Description

Son conference implementation method, secret meeting implementation method, device and terminal equipment

Technical field

The present invention relates to the network communications technology field, be specifically related to son conference implementation method, son conference implement device, secret meeting implementation method, secret meeting implement device and terminal equipment.

Background technology

(IP Multimedia Subsystem, (Session Initiated Protocol SIP) realizes calling out and the signaling controlled function IP Multimedia System IMS) to use initial session protocol.Attending a meeting between user and the multimedia conferencing server of attending multimedia conference realized the interactive function of multimedia conferencing by SIP, other agreement of cooperating with SIP.

The application scenarios that can occur the coexistence of main meeting and son conference in the multimedia conferencing, as the user that attends a meeting wishes to carry out meeting privately (Sidebar or Sub-Conference) with designated user when active conference is carried out.The meeting of carrying out is called son conference privately, and active conference is called main meeting, and designated user can be that the user that attends a meeting in the main meeting also can be the user that attends a meeting in the non-main meeting.

During son conference carried out, master's meeting user that attends a meeting in son conference Central Plains can receive the session content of main meeting.In order to protect the privacy of son conference, the user that attends a meeting who does not allow not add in the main meeting son conference usually obtains the session content of son conference.

At present, realize that the technical scheme of son conference is: Conference server receives the son conference request to create of certain user that attends a meeting in the main meeting, and Conference server Resources allocation, establishment son conference example also return the son conference sign.Carry out afterwards that son conference conversation media type is consulted, son conference such as user's invitations of attending a meeting in the son conference activates and moves.Conference server selects to be realized respectively by relatively independent two conference control center (Conference Focus) of resource allocation the establishment and the conference session control of main meeting, son conference on the management of meeting example, main conference control center (Main Conference Focus) in the corresponding Conference server of promptly main meeting example, the son conference control centre (Sidebar Focus) in the corresponding Conference server of son conference example.Main Conference Focus carries out main conference session content exchange by main conference session and the main meeting user that attends a meeting, and Sidebar Focus attends a meeting by son conference session and sub-session, and to carry out the son conference session content mutual for the user.Main conference session, son conference session are two separate conference sessions.

When son conference activates, Conference server invites main conference control center to add son conference, like this, Sidebar Focus is after receiving the next main conference session content of MainConference Focus transmission, with main conference session content and son conference session content audio mixing, and to the son conference session content of user after sending audio mixing of attending a meeting, the user can either receive main conference session content thereby son conference is attended a meeting, and also can receive the son conference session content.

In realizing process of the present invention, the inventor finds: though technique scheme has realized son conference, but, because main conference session content is merely able to be received by the main meeting user that attends a meeting, thus only when the user that attends a meeting in the son conference be that main meeting just allows the output of main conference session to son conference when attending a meeting the user simultaneously; Otherwise Sidebar Focus can't carry out the distribution of session content.That is to say, when a non-main meeting is attended a meeting the user when participating in son conference, can't realize of the output of main conference session content to son conference, perhaps when Sidebar Focus has received main conference session input (being that each current son conference is attended a meeting with being the main meeting user that attends a meeting per family simultaneously), can't admit the new non-main meeting user that attends a meeting to add son conference.And, technique scheme do not consider yet son conference create finish after the control problem of boss's conference session, for example when the user that attends a meeting in the son conference be main meeting when attending a meeting the user simultaneously, can not realize that main conference session content is whether to the control of this user's output of attending a meeting.In addition, this technical scheme does not have to consider to attend a meeting the user from how continuing to receive the problems such as release of son conference session and the preceding son conference session of main meeting termination after son conference switches back main meeting yet.

On the other hand, because existing son conference is realized leading in the technical scheme, son conference control centre is separate, therefore, participate in the employed terminal equipment of the user that attends a meeting main, son conference simultaneously and must set up and keep separate conference session respectively with master, son conference control centre.And in actual applications, be not that all terminal equipments all possess the parallel session ability, thereby cause some user that attends a meeting to participate in boss's meeting simultaneously.

Embodiment

The present invention can realize son conference by two kinds of different embodiment, wherein a kind of embodiment of son conference that realizes is: create independently son conference control centre, and on the basis that utilizes parallel each other main conference session, son conference session, adopt that main conference status information will be led, son conference associates, with carry out the distribution control of main conference session content in son conference, and son conference is followed, and main meeting adjourned and related control such as termination; The another kind of embodiment of son conference that realizes is: reuse main conference control center, utilize main conference session for simultaneously for main meeting user's the son conference user that attends a meeting that attends a meeting provides sidebar, perhaps utilize main conference session for user's son conference is attended a meeting the user, the user that attends a meeting that only participates in son conference provides sidebar for main meeting is attended a meeting simultaneously; Promptly utilize unique main conference control center to come main conference session, son conference session are controlled simultaneously.

Below above-mentioned two kinds of embodiment that realize son conference are described respectively.

Embodiment one, on the basis that utilizes parallel each other main conference session, son conference session, the main conference status information of passing through to obtain has in advance realized the association of main meeting, son conference; Like this, in follow-up son conference implementation procedure,, therefore, can realize the son conference session control easily because main meeting, son conference are interrelated.

In embodiment one, son conference control centre need obtain main conference status information.Son conference control centre can adopt the mode of subscription to obtain main conference status information, certainly, main conference control center also can be initiatively with the regular or irregular son conference control centre that transfers to of main conference status information, transmission etc. when irregular transmission here such as main conference status information change.Main conference status information can comprise: the main meeting user list of attending a meeting.Main conference status information can also further comprise on the basis of user list comprising that main meeting is attended a meeting: in the information such as main conference session medium type, main meeting control strategy a certain or two.The content that main conference status information comprises can be content that existing at present main conference status information comprises.The content that main conference status information comprises can be determined according to practical application.Above-mentioned main meeting control strategy can comprise: main meeting whether locked promptly main meeting whether allow again new user attend a meeting, and the user's that attends a meeting information such as speech duration in one or multinomial.The content that main meeting control strategy comprises can be the present content that comprises of existing main meeting control strategy equally.And the content that main meeting control strategy comprises can be determined according to practical application.Main conference status information can be subscribed to by son conference control centre in creating the son conference process, also can subscribe to main conference status information after successfully creating son conference.Embodiment of the present invention do not limit particular content that main conference status information and main meeting control strategy comprise, also not the siding stopping conference control center obtain main conference status information specific implementation, and subscribe to opportunity etc. of main conference status information.

For son conference control centre, main conference status information can be used for judging respectively attend a meeting user's the state of attending a meeting of son conference, and whether the user that attends a meeting that promptly can utilize main conference status information to judge in the son conference has also participated in main meeting when participating in son conference.That is to say that the user that attends a meeting who utilizes main conference status information can help son conference control centre to judge in the son conference has only participated in son conference, has still participated in boss's meeting simultaneously.

Son conference among the embodiment one can be the son conference of setting up according to the meeting control strategy.The process of setting up son conference according to the meeting control strategy can receive the main meeting son conference request to create that the user sends of attending a meeting for: Conference server.The user that attends a meeting can pass through the conferencing resource access mechanism that Conference server supports the son conference request to create is committed to Conference server in main meeting; For example, the main meeting user that attends a meeting inserts inlet (Portal) by meeting the son conference request to create is committed to Conference server; Again for example, the main meeting user that attends a meeting passes through the long-range assistant (Remote Assistance) that auxiliary conference applications parameter is provided with the son conference request to create is committed to Conference server.Embodiment of the present invention does not limit the main meeting user that attends a meeting and sends the specific implementation process of son conference request to create.

Can carry main meeting identification, son conference subject information, son conference attend a meeting user list information, son conference conversation media type and son conference control strategy in the son conference request to create.The son conference control strategy can comprise: whether whether son conference receives main conference session content, son conference allows the non-main meeting user that attends a meeting to participate in son conference or the like.The information of carrying in the above-mentioned son conference request to create also can transfer to Conference server by multiple messages.Embodiment of the present invention is not carried the particular content of information, particular content and above-mentioned each transmission of Information mode of son conference control strategy in the request of siding stopping conference creation.

Conference server obtains the meeting control strategy after receiving the son conference request to create, the meeting control strategy here is different from above-mentioned son conference control strategy, and the meeting control strategy here is used to judge whether allow to create son conference.The meeting control strategy can be main meeting control strategy, for example, Conference server obtains main meeting control strategy from Main Conference Focus, and certainly, Conference server also can obtain the meeting control strategy that is used to judge whether to allow to create son conference from other network equipment.

Conference server is carried out the follow-up creation operation of son conference, to create son conference after utilizing meeting control strategy (as main meeting control strategy) to determine permission establishment son conference.The creation operation here can comprise: distribute to realize that main meeting that the required resource of sidebar, notice send the son conference request to create user's son conference of attending a meeting creates successfully or the like.Distribute and realize that the required resource of sidebar can comprise: media transmission channel of the son conference session between the user or the like that Sidebar Focus, the Sidebar Focus of establishment son conference example correspondence sets up and each son conference is attended a meeting.The creation operation here can adopt existing various son conference creation operation, and embodiment of the present invention does not limit the processing procedure that creation operation specifically comprises.

Through above-mentioned each operate successfully set up son conference after, son conference session and main conference session are two parallel conference sessions, the corresponding Main Conference of promptly main meeting example Focus, the corresponding Sidebar Focus of son conference example, Main Conference Focus carries out the mutual of main conference session content by main conference session and the main meeting user that attends a meeting, Sidebar Focus by son conference session and son conference attend a meeting the user carry out the son conference session content alternately.Can be the user that attends a meeting who only participates in main meeting with the main meeting of the mutual main conference session content of the Main Conference Focus user that attends a meeting; Also can be the user and participate in the user that attends a meeting of main meeting, son conference simultaneously of attending a meeting that only participates in main meeting.Can be the user that attends a meeting that only participates in son conference with the sub main meeting of the mutual son conference session content of the Sidebar Focus user that attends a meeting; Also can be the user that attends a meeting who attends a meeting the user and participate in main meeting, son conference simultaneously that only participates in son conference.

In embodiment one, main meeting is attended a meeting, and can to pass through that Main Conference Focus, SidebarFocus transfer in the son conference be main meeting user's the son conference user that attends a meeting that attends a meeting simultaneously for main conference session content that the user sends, is that main meeting attend a meeting the main conference session content that the user sends of user's son conference of attending a meeting can be passed through Sidebar Focus, Main Conference Focus and transfers to main meeting in the main meeting user that attends a meeting simultaneously in the son conference.

When being that attend a meeting user's son conference of main meeting is attended a meeting the user need receive main conference session content the time simultaneously in the son conference, Sidebar Focus can invite Main Conference Focus to add son conference.Sidebar Focus can be that main meeting is attended a meeting user's son conference when attending a meeting the main conference session request of reception that the user sends receiving in the son conference first simultaneously, invites Main Conference Focus to add son conference.Certainly, Sidebar Focus also can invite Main Conference Focus to add son conference in other cases, for example, when the son conference control strategy comprises when allowing son conference to receive main conference session content, after son conference was successfully created, Sidebar Focus invited Main ConferenceFocus to add son conference.

After Main Conference Focus adds son conference, Main Conference Focus can be to the main conference session content after Sidebar Focus sends audio mixing, but do not receive the son conference session content, be that Main Conference Focus participates in son conference as only sending out the virtual user of attending a meeting who does not receive (Send only), that is to say that Main Conference Focus can be half-duplex channel to the main conference session passage (being media transmission channel) of Sidebar Focus.

After Sidebar Focus receives main conference session content, be responsible for the distribution of the main conference session content of control in son conference, to guarantee that only having the user that attends a meeting who receives authority in the son conference can receive main conference session content.Sidebar Focus can be that main meeting user's the son conference user that attends a meeting that attends a meeting sends main conference session content in son conference according to the user list information of attending a meeting of the main meeting in the main conference status information simultaneously, Sidebar Focus also can be according to the main meeting user list information of attending a meeting, receive main conference session request and be simultaneously main meeting user's the son conference user that attends a meeting that attends a meeting and send main conference session content in son conference, Sidebar Focus also can be according to the main meeting user list information of attending a meeting, stop to receive main conference session request and be simultaneously main meeting user's the son conference user that attends a meeting that attends a meeting and send main conference session content in son conference.Sidebar Focus can also according to main meeting attend a meeting user list information, to receive main conference session request, stop to receive main conference session request be that main meeting user's the son conference user that attends a meeting that attends a meeting sends main conference session content simultaneously in son conference.

Can carry main meeting identification in the main conference session request of reception in the embodiment of the present invention, be that main meeting user's the son conference user that attends a meeting that attends a meeting need receive main conference session content to show in the son conference simultaneously.Sidebar Focus is that main meeting user's the son conference situation that the user sends main conference session content of attending a meeting of attending a meeting can comprise the following mode that exemplifies simultaneously in son conference:

To allow in the son conference be that main meeting user's the son conference user that attends a meeting that attends a meeting receives main conference session content simultaneously if example 1 Sidebar Focus determines according to the son conference control strategy, then can be directly to determine in the son conference according to the user list information of attending a meeting from the main meeting of Main Conference Focus acquisition be main meeting user's the son conference user that attends a meeting that attends a meeting to Sidebar Focus simultaneously, and the main conference session content that will receive to send in the son conference be main meeting user's the son conference user that attends a meeting that attends a meeting all the time.

Example 2, determine to forbid in the son conference being that main meeting user's the son conference user that attends a meeting that attends a meeting receives under the situation of main conference session content simultaneously according to the son conference control strategy at Sidebar Focus, if Sidebar Focus receives the son conference main conference session request of reception that the user sends of attending a meeting, then Sidebar Focus can determine son conference that needs the receive main conference session user that attends a meeting according to receiving main conference session request.If it is the main meeting user that attends a meeting simultaneously that Sidebar Focus determines son conference that needs the receive main conference session content user that attends a meeting according to the user list information of attending a meeting from the main meeting of Main Conference Focus acquisition, then Sidebar Focus can send main conference session content to the son conference that the needs of determining the receive main conference session user that attends a meeting, otherwise Sidebar Focus does not send main conference session content to the above-mentioned son conference that need the to receive main conference session content user that attends a meeting.The user that attends a meeting that the needs here receive main conference session content sends the user that attends a meeting who receives main conference session request, also can be to receive the user that attends a meeting that the needs of indicating in the main conference session request receive main conference session.That is to say,, can oneself send the main conference session request that receives when being that attend a meeting user's son conference of main meeting is attended a meeting the user need receive main conference session content the time simultaneously in the son conference; Also can attend a meeting the user on behalf of sending the main conference session request that receives by other son conference, and on behalf of at least one son conference that carries appointment in the main conference session request of reception that sends user that attends a meeting, the user that attends a meeting can comprise the son conference of this appointment: be main meeting user's the son conference user that attends a meeting that attends a meeting simultaneously in the son conference.

Example 3, determine according to the son conference control strategy at Sidebar Focus that to allow in the son conference be that main meeting user's the son conference user that attends a meeting that attends a meeting receives under the situation of main conference session content simultaneously, if Sidebar Focus receives that son conference attends a meeting that the user sends stops to receive main conference session request, then Sidebar Focus can determine son conference that needs stop the to receive main conference session user that attends a meeting according to stopping to receive main conference session request; The son conference that Sidebar Focus no longer stops to receive main conference session content to the needs user that attends a meeting sends main conference session content, and Sidebar Focus is that main meeting user's the son conference user that attends a meeting that attends a meeting sends main conference session content according to user list information other except that needs stop to receive the user that attends a meeting of main conference session content in son conference of attending a meeting from the main meeting of Main Conference Focus acquisition simultaneously.The son conference that the needs here stop the to receive main conference session user that attends a meeting sends the son conference that stops the to receive main conference session request user that attends a meeting, and also can be to stop to receive son conference that the needs of indicating in the main conference session request stop the to receive main conference session user that attends a meeting.That is to say,, can oneself send to stop to receive main conference session request when being that attend a meeting user's son conference of main meeting is attended a meeting the user need stop to receive main conference session content the time simultaneously in the son conference; Also can stop to receive main conference session request on behalf of transmission by other son conference user that attends a meeting, stop to receive at least one son conference that carries appointment in main conference session request user that attends a meeting this moment, the user that attends a meeting can comprise the son conference of this appointment: be main meeting user's the son conference user that attends a meeting that attends a meeting simultaneously in the son conference.

Sidebar Focus receive stop to receive main conference session request after, can judge that whether the son conference that needs to stop the to receive main conference session content user that attends a meeting is the main meeting user that attends a meeting simultaneously, judging this son conference user that attends a meeting is that main meeting is attended a meeting behind the user simultaneously, stops sending main conference session content to this user that attends a meeting again.Certainly, Sidebar Focus also can not carry out this deterministic process, no matter promptly this son conference attends a meeting whether receive main conference session content before the user, does not send main conference session content to this son conference user that attends a meeting without exception; SidebarFocus directly attends a meeting user list information to being that main meeting user's the son conference son conference that stops to receive main conference session except that needs other son conference the user user that attends a meeting that attends a meeting that attends a meeting among the user that attends a meeting sends main conference session content simultaneously according to main meeting.That is to say, here do not send the implication that main conference session content comprises two aspects to this son conference user that attends a meeting: one receives under the situation of main conference session content for the user that attends a meeting at this son conference, stop to send main conference session content to this user that attends a meeting, two for the user that attends a meeting at this son conference does not receive under the situation of main conference session content, still do not send main conference session content to this user that attends a meeting.

Sidebar Focus receive stop to receive main conference session request after, can make the following judgment: whether all son conferences that receive main conference session content in son conference user that attends a meeting all stops to receive main conference session content, all stop to receive main conference session content if judge all son conferences that in son conference, receive main conference session user that attends a meeting, then Sidebar Focus sends request to Main Conference Focus, withdraw from son conference with request Main Conference Focus, Main Conference Focus discharges the main conference session between Main Conference Focus and the Sidebar Focus after receiving this request.

In embodiment one, be that main meeting user's the son conference user that attends a meeting that attends a meeting can select to switch back main meeting as required simultaneously in the son conference.Be that main meeting user's the son conference user that attends a meeting that attends a meeting can send handoff request to Sidebar Focus simultaneously, to switch back main meeting.When being that attend a meeting user's son conference of main meeting is attended a meeting after the user switches back main meeting simultaneously in the son conference, this main meeting user that attends a meeting still can require to receive the son conference session content, at this moment, the son conference session content need transfer to Main Conference Focus from Sidebar Focus, transfers to this main meeting user that attends a meeting from Main Conference Focus again.Be to set up the son conference session from Sidebar Focus to Main Conference Focus, Main Conference Focus can invite Sidebar Focus to add to become owner of meeting.Embodiment of the present invention can be updated to two-way conference session passage with the unidirectional main conference session passage from Main Conference Focus to Sidebar Focus, also can rebulid list/two-way son conference session channel, as rebulid unidirectional son conference session channel from SidebarFocus to Main Conference Focus from Sidebar Focus to Main Conference Focus.

Sidebar Focus add become owner of meeting after, Sidebar Focus can be to the son conference session content after Main Conference Focus sends audio mixing, and Sidebar Focus can receive main conference session content, also can not receive main conference session content.After Main ConferenceFocus receives the son conference session content, be responsible for the distribution of control son conference session content in the user is attended a meeting in main meeting, can receive the son conference session content to guarantee only to have in the main meeting the main meeting that the receives authority user that attends a meeting.Having the main meeting that the receives authority user that attends a meeting can comprise: the main meeting of switching back main meeting attend a meeting the user, do not switch but ask the main meeting of the reception son conference session content user that attends a meeting.

Main Conference Focus can send the son conference session content according to the son conference state information of obtaining (as the son conference user list information of attending a meeting) needs to receive the son conference session content in main meeting the main meeting user that attends a meeting, and sends the son conference session content as the user that attends a meeting to the main meeting of switching back main meeting.Main Conference Focus can according to son conference attend a meeting user list information, receive the son conference conversation request and send the son conference session content to the main meeting of switching the back main meeting user that attends a meeting, Main Conference Focus also can according to son conference attend a meeting user list information, reception son conference conversation request, stop to receive the son conference conversation request and send the son conference session content to the main meeting of switching the back main meeting user that attends a meeting.Above-mentioned Main Conference Focus attends a meeting to the main meeting of switching back main meeting, and to send the mode that specifically exemplifies that the situation of son conference session content comprises and above-mentioned Sidebar Focus be that attend a meeting user's son conference of main meeting attends a meeting that to send the situation of main conference session content similar for the user in son conference to the user simultaneously, its difference comprises: receive and to carry the son conference sign in the son conference conversation request, stop to receive and also carry the son conference sign in the son conference conversation request.Main Conference Focus no longer describes in detail at this to the main meeting of switching the back main meeting mode that specifically exemplifies that the user sends the son conference session content of attending a meeting.

The main meeting user that attends a meeting can ask to withdraw from main meeting.Main Conference Focus attends a meeting after the main request for conference of withdrawing from of user receiving main meeting, discharges and attend a meeting main conference session between the user of main meeting, discharges main conference session and comprises: discharge main conference session passage.MainConference Focus can also attend a meeting after the main request for conference of withdrawing from of user receiving main meeting, no longer sends main conference session content to this main meeting user that attends a meeting, and only sends the son conference session content to it.And, Main Conference Focus can also attend a meeting after the main request for conference of withdrawing from of user receiving main meeting, the main meeting user that attends a meeting is withdrawed from the information notice Sidebar Focus of main meeting, and promptly MainConference Focus sends main conference status information change notice to Sidebar Focus.Like this, receive in son conference under the situation of son conference session this main meeting user that attends a meeting, Sidebar Focus can only send the son conference session content to this user that attends a meeting according to this notice.

Need to prove, in above-mentioned flow process at Fig. 5 is described, the sequencing that on behalf of operation, number of steps carry out, for example, the step 7 among Fig. 5, step 9, step 11 can be carried out simultaneously, also can reversed order; Again for example, step 13, step 15, step 17 can be carried out simultaneously, also can reversed order; Also have, step 23, step 25, step 27 can be carried out simultaneously, also can reversed order or the like.

Embodiment two, reuse the conference control center of main meeting.

Utilize the conference control center of existing main meeting to realize main meeting, be that the user that attends a meeting who only participates in son conference realizes son conference for the user that attends a meeting who only participates in main meeting, for the user that attends a meeting who participates in boss's meeting simultaneously realizes main meeting and son conference, promptly utilize the conference control center of main meeting that main conference session, son conference session are controlled simultaneously, on SIP session aspect, main meeting and son conference have been reused conference session.

In embodiment two, son conference can have the son conference sign, but the son conference sign is an another name of main meeting identification.The son conference sign is as Sub-conference URI.Attend a meeting after the user participates in son conference in main meeting, the conference session between the conference control center of this attend a meeting user and main meeting (being called conference control center in following description) can also can be used as the son conference session with the conference session of deciding.

Son conference constructive process among the embodiment two can receive the main meeting son conference request to create that the user sends of attending a meeting for: Conference server.The user that attends a meeting can pass through the conferencing resource access mechanism that Conference server supports the son conference request to create is committed to Conference server in main meeting, for example, the user that attends a meeting inserts Portal by meeting the son conference request to create is committed to Conference server in main meeting, again for example, the main meeting long-range assistant that the user passes through auxiliary conference applications parameter setting that attends a meeting is committed to Conference server with the son conference request to create.Embodiment of the present invention does not limit the main meeting user that attends a meeting and sends the specific implementation process of son conference request to create.

Can carry main meeting identification, son conference subject information, son conference attend a meeting user list information and son conference conversation media type etc. in the son conference request to create.Can also optionally carry the son conference control strategy in the son conference request to create, certainly, the son conference control strategy also can set in advance at the Conference server place.The son conference control strategy can comprise: whether the user that attends a meeting who whether allows to participate in main meeting son conference simultaneously receives main conference session content, allow the non-main meeting user that attends a meeting to participate in son conference or the like.The information of carrying in the above-mentioned son conference request to create also can transfer to Conference server by multiple messages.Embodiment of the present invention is not carried the particular content of information, particular content and above-mentioned each transmission of Information mode of son conference control strategy in the request of siding stopping conference creation.

Conference server can directly be carried out the son conference creation operation after receiving the son conference request to create, also can determine whether carrying out the son conference creation operation according to the meeting control strategy.The meeting control strategy here is different from above-mentioned son conference control strategy, and the meeting control strategy here is used to judge whether allow to create son conference, and the meeting control strategy can be main meeting control strategy.Under the situation that adopts the meeting control strategy, Conference server at first obtains the meeting control strategy, for example, Conference server obtains main meeting control strategy from conference control center (Conference Focus), certainly, Conference server also can obtain the meeting control strategy that is used to judge whether to allow to create son conference from other network equipment.Conference server is set up son conference by reusing conference control center after utilizing the meeting control strategy to determine permission establishment son conference, promptly do not need to create the independently Conference Focus of son conference example correspondence.Main conference session passage and son conference session channel can be reused existing conference session passage (promptly main conference session passage and son conference session channel are shared same conference session passage), and main conference session passage and son conference session channel also can be separate conference session passage.Under the identical situation of boss's conference session medium type, main conference session passage and son conference session channel can adopt the mode of reusing the conference session passage, also can adopt the mode of separate conference session passage; Under boss's conference session medium type situation inequality, main conference session passage and son conference session channel need adopt the mode of separate conference session passage.

After successfully creating son conference, for the user that attends a meeting who participates in master, son conference simultaneously, the son conference session only is session in logic, son conference session and main conference session are not two parallel sessions, but the conference session of reusing, promptly main meeting example corresponding ConferenceFocus, the also corresponding Conference Focus of son conference example.Conference Focus carries out the mutual of main conference session content, son conference session content by the conference session of reusing and main meeting user, the son conference user that attends a meeting that attends a meeting.

Conference Focus can by main conference session and main meeting attend a meeting mutual and Conference Focus that the user carries out main conference session content and/or son conference session content can pass through son conference session and son conference attend a meeting the user carry out son conference session content and/or main conference session content alternately.That is to say, Conference Focus utilizes the user interactions conference session content of attending a meeting with respectively attend a meeting conference session and the main meeting of participation, son conference between the user, conference session with the conference session of deciding, is used as the son conference session when the user that attends a meeting participates in son conference when the user that attends a meeting participates in main meeting.When conference session when deciding conference session, do not represent the user that attends a meeting only can receive main conference session content by main conference session, the user that attends a meeting in actual applications can receive main conference session content or receives the son conference session content or receive main conference session content and son conference session content by main conference session.Equally, when conference session is used as the son conference session, do not represent the user that attends a meeting only can receive the son conference session content, the user that attends a meeting can receive the son conference session content or receives main conference session content or receive main conference session content and son conference session content by the son conference session.

Carry out under the mutual situation of main conference session content, son conference session content the main conference session content that can adopt the control means of signaling to distinguish the user that attends a meeting to send, son conference session content or the like by the conference session of reusing and main meeting user, the son conference user that attends a meeting that attends a meeting at Conference Focus.For example, when the user that attends a meeting need send main conference session content, can send the transmission conference session request that carries main meeting identification earlier, with notice Conference Focus: the conference session content of this follow-up transmission of user of attending a meeting is main conference session content.Then, this user that attends a meeting sends main conference session content to Conference Focus again.When the user that attends a meeting need send main conference session content, the user that attends a meeting also can increase the main meeting identification that is different from the son conference sign in the main conference session content that sends, Conference Focus can resolve the meeting identification information in the main conference session content earlier, determine that according to the meeting identification information that parses the conference session content that receives is main conference session content, or the son conference session content.Undertaken under the mutual situation of session content by separate main conference session passage, son conference session channel and main meeting user, the son conference user that attends a meeting that attends a meeting at Conference Focus, it is main conference session content, still son conference session content that the difference of the passage that Conference Focus can be by identification transmitting conference session content is determined conference session content that the user that attends a meeting sends.Thereby no matter adopt and reuse the conference session channel mode, still adopt independently conference session channel mode, ConferenceFocus all can realize to the user that attends a meeting who only participates in main meeting, only participating in the user that attends a meeting of son conference, participate in the accurate reception of the session content that the user that attends a meeting of main meeting son conference sends simultaneously.

Conference Focus can send the conference session content to son conference user or the main meeting user that attends a meeting that attends a meeting by the conference session passage shared after identifying the conference session content that receives; Perhaps send the conference session content to son conference user or the main meeting user that attends a meeting that attends a meeting by separate main conference session passage, son conference session channel.

Conference Focus can be sent to the main conference session content that identifies the user that attends a meeting who needs to receive main conference session content; The user that attends a meeting who need to receive main conference session content can comprise: the user and participate in son conference and require to receive main conference session content and the granted son conference user that attends a meeting of attending a meeting who participates in main meeting.Conference Focus can be sent to the son conference session content that identifies the user that attends a meeting who needs to receive the son conference session content, the user that attends a meeting who need to receive the son conference session content can comprise: participate in the user that attends a meeting of son conference, and participate in main meeting and require to receive the son conference session content and the granted main meeting user that attends a meeting.For example, be that main meeting user's the son conference customer requirements of attending a meeting of attending a meeting receives main conference session content simultaneously in the son conference, Conference Focus is that main meeting is attended a meeting behind the user definite this son conference user that attends a meeting simultaneously, can will send to this son conference user that attends a meeting behind the conference session content audio mixing that receive.The conference session content that the Conference Focus here receives can be main conference session content and/or son conference session content.

The user that attends a meeting who participates in main meeting son conference simultaneously can select whether to receive main conference session content, son conference session content, and the user that attends a meeting who participates in main meeting, son conference simultaneously also can select to withdraw from main meeting or withdraw from son conference, Conference Focus can send the conference session content of mating with the user's that attends a meeting selection to the user that attends a meeting, thereby make the user that attends a meeting can selectivity receive the conference session content, the user that realized attending a meeting receives the control of conference session content.

Though the foregoing description one also can realize sending, receiving the control of conference session content,, the technological means that both adopt is different.For example, in embodiment one, Sidebar Focus need subscribe to main conference status information, so that boss's meeting is associated, thereby son conference is carried out the control related with main meeting, and in embodiment two, Conference Focus can pass through alone processing fully to be operated association control is carried out in boss's meeting, thereby do not need the cooperation of Sidebar Focus, promptly do not need to carry out subscription and wait operation; Again for example, in embodiment one, need receive main conference session content if participate in the user that attends a meeting of boss's meeting simultaneously, then Sidebar Focus need invite Main Conference Focus to add son conference, sets up main conference session passage between Sidebar Focus and Main Conference Focus; And in embodiment two, Conference Focus can pass through to handle alone the boss's conference session content after the user that attends a meeting who participates in main meeting, son conference simultaneously sends audio mixing fully, thereby do not need the cooperation of Sidebar Focus, promptly do not need execution to invite, set up operations such as main conference session passage.Again for example, in embodiment one, need switch back main meeting if participate in the user that attends a meeting of boss's meeting simultaneously, and in main meeting, receive the son conference session content, then Main Conference Focus need invite Sidebar Focus to add to become owner of meeting, between Sidebar Focus and Main Conference Focus, set up the son conference session channel or utilize two-way conference session passage between the two, and in embodiment two, because Conference Focus can handle alone to the user that attends a meeting fully and send corresponding conference session content, therefore, do not need to carry out this invitation, set up operations such as son conference session channel.The control that it still is the son conference session content that the user that attends a meeting that switching among the embodiment two can be used for participating in simultaneously boss's meeting sends main conference session content; Also have, in embodiment one, when the user that attends a meeting who participates in boss's meeting simultaneously need withdraw from main meeting, Main Conference Focus need be according to attend a meeting user's the situation of attending a meeting of main meeting, whether decision notifies the meeting of Sidebar Focus terminator, and in embodiment two, Conference Focus can pass through to operate alone the termination of controlling boss's meeting fully, thereby do not need the cooperation of Sidebar Focus, do not need operations such as exercise notice.Many differences of embodiment two and embodiment one adopt the conference control center of reusing main meeting by implementing two, promptly reuse the conference session of main meeting and produce.Conference session content to embodiment two sends control below, reception is controlled, withdrawed from meeting, termination meeting etc. and describes.

Conference Focus can be known the user's that respectively attends a meeting in boss's meeting the state of attending a meeting, that is to say, Conference Focus can know the user that attends a meeting in boss's meeting be only participated in main meeting, or only participated in son conference, XOR is to have participated in main meeting and son conference simultaneously.Conference Focus can be known the user's that respectively attends a meeting in boss's meeting the state of attending a meeting according to main meeting user list information, the son conference user list information of attending a meeting of attending a meeting.

Conference Focus can send main conference session content according to the son conference control strategy judges whether to participate in simultaneously main meeting in son conference the son conference user that attends a meeting.The son conference control strategy can be set to: allow to send main conference session content and son conference session content to the user that attends a meeting who participates in boss's meeting simultaneously, promptly under default situations, Conference Focus sends main conference session content and son conference session content to the user that attends a meeting who participates in boss's meeting simultaneously; At this moment, the user that attends a meeting who participates in boss's meeting simultaneously can stop to receive main conference session request or stop to receive the son conference conversation request controlling it and only receiving the conference session content that needs by sending.Stop to receive in the main conference session request and can carry main meeting identification, can also optionally carry at least one user profile of attending a meeting of appointment; Stop to receive in the son conference conversation request and can carry main meeting identification, can also optionally carry at least one user profile of attending a meeting of appointment.

What participate in boss's meeting simultaneously attends a meeting the user after stopping to receive main conference session content, can also continue to receive main conference session content again by send the main conference session request of reception to Conference Focus.What participate in boss's meeting simultaneously attends a meeting the user after stopping to receive the son conference session content, can also continue to receive the son conference session content again by send reception son conference conversation request to Conference Focus.

The son conference control strategy also can be set to: forbid sending main conference session content to the user that attends a meeting who participates in boss's meeting simultaneously, promptly under default situations, Conference Focus only sends the son conference session content to the user that attends a meeting who participates in boss's meeting simultaneously.At this moment, the user that attends a meeting who participates in boss's meeting simultaneously can pass through to send and receives main conference session request and control it and receive boss's conference session content.Be that ConferenceFocus can only send the son conference session content according to son conference user list information all in son conference users that attends a meeting that attends a meeting, ConferenceFocus also can according to boss's meeting attend a meeting user list information, to receive main conference session request be that main meeting user's the son conference user that attends a meeting that attends a meeting sends boss's conference session content simultaneously in son conference.

In embodiment two, the user that attends a meeting that can receive boss's conference session content can be by stopping to receive main conference session request, stopping to receive the son conference conversation request and control it and only receive the son conference session content or only receive main conference session content.The user that attends a meeting who participates in boss's meeting at the same time only can receive under the situation of main conference session content, and the user that attends a meeting can receive boss's conference session content by send reception son conference conversation request to Conference Focus.The user that attends a meeting who participates in boss's meeting at the same time only can receive under the situation of son conference session content, and the user that attends a meeting can receive boss's conference session content by send the main conference session request of reception to Conference Focus.That is to say, Conference Focus can according to boss's meeting attend a meeting user list information, receive main conference session request, receive the son conference conversation request, stop to receive main conference session request, stop to receive the son conference conversation request and send corresponding conference session content to the user that attends a meeting.

In embodiment two, receive main conference session request and can carry at least one son conference of appointment user profile of attending a meeting, at least one son conference that also can not carry appointment user profile of attending a meeting.Under the son conference that does not carry appointment is attended a meeting the situation of user profile, can represent to send the user that attends a meeting who receives main conference session request and need receive main conference session content.Under the son conference that carries appointment was attended a meeting the situation of user profile, the son conference that can the represent appointment user that attends a meeting need receive main conference session content.That is to say,, can oneself send the main conference session request that receives when being that attend a meeting user's son conference of main meeting is attended a meeting the user need receive main conference session content the time simultaneously in the son conference; Also can be by other user that attends a meeting on behalf of sending the main conference session request that receives.

In embodiment two, stop to receive son conference that main conference session request can the carry appointment user profile of attending a meeting, at least one son conference that also can not carry appointment user profile of attending a meeting.Under the son conference that does not carry appointment is attended a meeting the situation of user profile, can represent to send the user that attends a meeting who stops to receive main conference session request and need stop to receive main conference session content.Under the son conference that carries appointment was attended a meeting the situation of user profile, the son conference that can the represent appointment user that attends a meeting need stop to receive main conference session content.That is to say,, can ownly initiatively send stop to receive main conference session request when being that attend a meeting user's son conference of main meeting is attended a meeting the user need stop to receive main conference session content the time simultaneously in the son conference; Also can stop to receive main conference session request on behalf of transmission by other user that attends a meeting.

In embodiment two, stop to receive at least one the main meeting that to carry appointment in son conference conversation request user profile of attending a meeting, at least one the main meeting that also can not carry appointment user profile of attending a meeting.Under the situation of user profile was attended a meeting in the main meeting of not carrying appointment, expression sends the user that attends a meeting who stops to receive the son conference conversation request need stop to receive the son conference session content.Under the situation of user profile was attended a meeting in the main meeting of carrying appointment, the main meeting of the expression appointment user that attends a meeting need stop to receive the son conference session content.That is to say,, can oneself send to stop to receive the son conference conversation request when main meeting is attended a meeting the user need stop to receive the son conference session content time; Also can stop to receive the son conference conversation request on behalf of transmission by other user that attends a meeting.

It is similar that Conference Focus among the embodiment two sends the mode of describing in the mode that specifically exemplifies that corresponding conference session content comprises and the foregoing description one that specifically exemplifies to the user that attends a meeting accordingly, no longer describes in detail at this.

In embodiment two, be that main meeting user's the son conference user that attends a meeting that attends a meeting can select to switch to main meeting as required or switch to son conference simultaneously in the son conference, switching among switching here and the embodiment one is inequality, the switching here represents to participate in simultaneously the user notification Conference Focus that attends a meeting of boss's meeting: the session content that this user that attends a meeting sends is that main conference session content still is the son conference session content, the switching here can realize that by the transmission conference session request that transmission carries meeting identification the meeting identification that sends in the conference session request can be main meeting identification, also can identify for son conference.Main meeting identification represents that the conference session content of the follow-up Conference of the being sent to Focus of this user that attends a meeting is main conference session content; The conference session content of the follow-up Conference of the being sent to Focus of son conference sign this user that attends a meeting of expression is the son conference session content.For example, be that main meeting user's the son conference user that attends a meeting that attends a meeting can send to son conference session handoff request (promptly carrying the transmission conference session request of son conference sign) to Conference Focus simultaneously in the son conference, with notice Conference Focus: the conference session content of this follow-up transmission of user of attending a meeting is the son conference session content.Again for example, be that main meeting user's the son conference user that attends a meeting that attends a meeting can send to main conference session handoff request (promptly carrying the transmission conference session request of main meeting identification) to Conference Focus simultaneously in the son conference, with notice Conference Focus: the conference session content of this follow-up transmission of user of attending a meeting is main conference session content.

The user that attends a meeting in the main meeting can ask to withdraw from main meeting.Can carry the main request for conference of withdrawing from of main meeting identification to Conference Focus transmission as the user that attends a meeting in the main meeting, withdraw from main meeting to represent this user's request of attending a meeting.Conference Focus attends a meeting after the main request for conference of withdrawing from of user receiving main meeting, need receive under the situation of son conference session content for conference session passage and this user that attends a meeting who shares at main conference session passage and son conference session channel, Conference Focus can not discharge and ask to withdraw from the operation of the conference session passage between the user of attending a meeting of main meeting; Do not need to receive under the situation of son conference session content for conference session passage and this user that attends a meeting who shares at main conference session passage and son conference session channel, Conference Focus can discharge and ask to withdraw from the operation of the conference session passage between the user of attending a meeting of main meeting; At main conference session passage and son conference session channel is under the situation of separate conference session passage, and Conference Focus can discharge the main conference session passage between the user of attending a meeting that main meeting is withdrawed from itself and request.ConferenceFocus receives and withdraws from after the main request for conference, and Conference Focus can upgrade attend a meeting user list and no longer send main conference session content to this user that attends a meeting of main meeting; The user still is the son conference user that attends a meeting if this is attended a meeting, and then Conference Focus can continue to send the son conference session content to this user that attends a meeting.

Conference Focus can also receive withdraw from main request for conference after, judge that whether all main meetings user that attends a meeting has withdrawed from main meeting, the user has withdrawed from main meeting if all main meetings are attended a meeting, then Conference Focus can carry out the operation of terminator meeting earlier, and then stops the operation of main meeting.When main conference session passage and son conference session channel were two separate conference session passages, the operation of terminator meeting can comprise: the son conference session channel that Conference Focus discharges and each son conference is attended a meeting between the user.

The user that attends a meeting in the son conference can ask to withdraw from son conference, can send the son conference request of withdrawing from that carries the son conference sign to Conference Focus as the user that attends a meeting in the son conference, withdraws from son conference to represent this user's request of attending a meeting.Conference Focus receive withdraw from the son conference request after, need receive under the situation of main conference session content for conference session passage and this user that attends a meeting who shares at main conference session passage and son conference session channel, Conference Focus can not discharge the operation of conference session passage.Do not need to receive under the situation of main conference session content for conference session passage and this user that attends a meeting who shares at main conference session passage and son conference session channel, Conference Focus can discharge the operation of conference session passage.At main conference session passage and son conference session channel is under the situation of separate conference session passage, and Conference Focus can discharge itself and this attend a meeting operation of the son conference session channel between the user.Conference Focus receive withdraw from the son conference request after, can upgrade attend a meeting user list and no longer send the son conference session content of son conference to this user that attends a meeting.The user still is the main meeting user that attends a meeting if this is attended a meeting, and then Conference Focus can continue to send main conference session content to this user that attends a meeting.

In addition, need to prove, above-mentionedly withdraw from main request for conference, withdraw from least one user profile of attending a meeting that also can carry appointment in the son conference request, need withdraw from main meeting or son conference with the user that attends a meeting of expression appointment.

Be elaborated to realizing son conference embodiment two below in conjunction with accompanying drawing.

Accompanying drawing 6 is the schematic diagram of the realization son conference of embodiment two.

Among Fig. 6, use the user that respectively attends a meeting of terminal 1, terminal 2, terminal 3 carrying out main meeting, use the user that attends a meeting of terminal 4 not participate in main meeting, but participated in son conference.Attend a meeting arbitrary attending a meeting among user 1, the user 2 that attends a meeting, the user 3 that attends a meeting with creating son conference by the terminal request of using per family, Conference server can judge whether to allow to create son conference according to main meeting control strategy, allow to create, and successfully created son conference after, attend a meeting user 1, the user 2 that attends a meeting, the user 3 that attends a meeting utilizes terminal, proceeds main meeting by main conference session, and the user 1 that attends a meeting, attend a meeting user 3 and the user 4 that attends a meeting utilize terminal, carry out son conference by the son conference session.Main conference session herein, son conference session are the conference session of reusing, promptly same conference session when the user that attends a meeting participates in main meeting with the conference session of deciding, when the user that attends a meeting participates in son conference as the son conference session.Main IMS conference medium transmission channel can be shared as the son conference media transmission channel, and perhaps main IMS conference medium transmission channel can be separate with the son conference media transmission channel.Because main meeting and son conference are reused same session, therefore main meeting and son conference are to be mutually related, and the Conference Focus of main meeting can carry out the conference session control related with main meeting to son conference.

Accompanying drawing 7 is the son conference visioning procedure figure of embodiment two.

Among Fig. 7, UE1, UE2, UE3, the UE4 terminal that the user uses of representing respectively respectively to attend a meeting, wherein: use the user that attends a meeting of UE1, UE2, UE3 to be the main meeting user that attends a meeting, promptly use the user that attends a meeting of UE1, UE2, UE3 to participate in the Main Conference Focus in the Conference server and preside over multimedia conferencing in many ways down, the media transmission channel of attending a meeting between user and the Main Conference Focus of use UE1, UE2, UE3 is respectively Dialog1, Dialog2, Dialog3; Use the user that attends a meeting of UE4 to be the non-main meeting user that attends a meeting, use the user that attends a meeting of UE4 to participate in the son conference of multimedia in many ways under the Main Conference Focus in the Conference server presides over the user that attends a meeting who uses UE1, UE3.

Of particular note, the Main Conference Focus among Fig. 7,8,9,10 is the ConferenceFocus that describes in the foregoing description two.In addition, for describing for purpose of brevity, in following description at accompanying drawing, the user that will attend a meeting sends by terminal equipment that information simply is described as UE1, UE2, UE3, UE4 send information.

Among Fig. 7, step 1, carry out in the process in main meeting, UE1 sends the son conference request to create to Conference server.The son conference request to create can be committed to Conference server by the conferencing resource access mechanism of Conference server support, and for example, the son conference request to create inserts or assist the long-range assistant of conference applications parameter setting etc. to be committed to Conference server by meeting.Can carry main meeting identification, son conference theme, son conference attend a meeting user list, son conference conversation media type and son conference control strategy or the like in the son conference request to create.Whether the son conference control strategy receives main conference session content, allows the non-main meeting user that attends a meeting to participate in son conference etc. as whether allowing the son conference user that attends a meeting.

Step 4, Conference server judge whether to accept the son conference request to create according to main meeting control strategy, if accept the son conference request to create, then Conference server utilizes the main meeting existing conference session of attending a meeting between user and the Conference server to realize the son conference session, therefore, Conference server is actually having the adjustment of main meeting example now at the resource deployment of son conference.Conference server equally need be for son conference distributes the son conference sign, to step 5; If Conference server is not accepted the son conference request to create, then this son conference constructive process finishes, and Conference server can return the response message that stops to create son conference to UE1.

Step 8, UE1 send son conference to Main Conference Focus and activate request after receiving the successful response message of son conference establishment.

Step 9, Main Conference Focus return response message to UE1 after receiving son conference activation request.

Step 10, UE1 return confirmation to Main Conference Focus after receiving response message, thus the success setting up son conference session Dialog1 ' on the existing main conference session Dialog1 between UE1 and the Main Conference Focus.That is to say that UE1 and the existing conference session of Main Conference Focus promptly can be used as main conference session, can be used as the son conference session again.

Step 11, Main Conference Focus attend a meeting user list information to the request of UE3 transmission invitation adding son conference according to son conference.

Step 12, UE3 return response message to Main Conference Focus after the request of receiving.

Step 13, Main Conference Focus return confirmation to UE3 after receiving response message, thus the success setting up son conference session Dialog3 ' on the existing main conference session Dialog3 between UE3 and the Main Conference Focus.

Step 14, Main Conference Focus attend a meeting user list to the request of UE4 transmission invitation adding son conference according to son conference.

Step 15, UE4 return response message to Main Conference Focus after the request of receiving.

Step 16, Main Conference Focus return confirmation to UE4 after receiving response message, thereby successfully set up the son conference session Dialog4 between UE4 and the Main Conference Focus.

In the process of above-mentioned establishment son conference, can adopt two kinds of different media transmission channel to set up mode.

Same media transmission channel is shared in mode one, main conference session and son conference session, and main IMS conference medium transmission channel is the son conference media transmission channel.That is to say that main conference session channels share is the son conference session channel.

Mode two, set up new media transmission channel for son conference separately in main conference session, main IMS conference medium transmission channel and son conference media transmission channel are separate, and promptly main conference session passage and son conference session channel are separate.

When main conference session medium type, when son conference conversation media type is identical, can adopt in aforesaid way one, the mode two any to set up the son conference media transmission channel.When main conference session medium type, when son conference conversation media type is inequality, need employing mode two to set up the son conference media transmission channel.

When employing mode one is set up the son conference media transmission channel, can adopt the transmission of signaling control conference session content, the reception of main conference session content, son conference session content is controlled by signaling as MainConference Focus, the user that attends a meeting controls the transmission of main conference session content, son conference session content by signaling.By signaling the reception of main conference session content, son conference session content is controlled and can be asked to realize to Main Conference Focus transmission SIP re-INVITE by the user that attends a meeting, wherein, Request URI in the SIPre-INVITE request is main meeting identification or son conference sign, and the session content that need receive with expression Main Conference Focus is main conference session content or son conference session content; The conversation media type specification can be carried in the MIME SDP message body of SIP re-INVITE request; Main Conference Focus can be set to " a=active " or " a=inactive " with activation attribute in corresponding IMS conference medium transmitting channel description " m " row according to the difference that begins to receive or stop to receive.

When employing mode two is set up the son conference media transmission channel, independently media transmission channel is used in the speech of user in different meetings owing to attend a meeting, therefore, Main Conference Focus can correctly to distinguish conference session content that the user that attends a meeting sends be main conference session content or from the conference session content by distinguishing media transmission channel.

Need to prove, in above-mentioned flow process at Fig. 7 is described, the sequencing that on behalf of operation, number of steps carry out, for example, the step 5 among Fig. 7, step 6 can be carried out simultaneously, also can reversed order; Again for example, step 11, step 14 can be carried out simultaneously, also can reversed order etc.

Be described in detail in main conference session, son conference session below for reusing conference session and sharing with under the same media transmission channel situation, the reception of main conference session content, son conference session content sends the implementation procedure of control.

Accompanying drawing 8 is that main conference session, the son conference session of embodiment two sends control flow chart.

The user that attends a meeting of use UE1, UE2 among Fig. 8, UE3 is the main meeting of the multimedia conferencing in many ways that participates at first Main Conference Focus together and the preside over user that attends a meeting, in main meeting is carried out, use the user that attends a meeting of UE1, UE3 to carry out son conference with the user that attends a meeting who uses UE4 again.As using the user that attends a meeting of UE2, that uses UE1, UE3 attends a meeting the user still in main meeting for other users that attend a meeting in the main meeting.The user that attends a meeting who uses UE4 is the son conference user that attends a meeting, and uses the user that attends a meeting of UE4 to have no right to receive main conference session content.Use the main conference session of respectively attending a meeting between user and the Main Conference Focus of UE1, UE2, UE3 to be respectively Dialog1, Dialog2, Dialog3, use the son conference session of respectively attending a meeting between user and the Main Conference Focus of UE1, UE3, UE4 to be respectively Dialog1 ', Dialog3 ', Dialog4.

Among Fig. 8, step 1, UE1 send to son conference session handoff request to Main Conference Focus, temporarily as the media transmission channel of son conference session Dialog1 ', promptly the media transmission channel between UE1 and the Main Conference Focus temporarily is the son conference special use with the media transmission channel of main conference session Dialog1 between UE1 and the MainConference Focus in request.UE1 send in son conference session handoff request, Request URI can be set to son conference sign " sub_conference@example.com ", can carry current session identification Dialog1 in " Replace " header field, parameter " conference-only " shows the main meeting identification main_conference@example.com that takies media transmission channel before the switching.This boss's conference session handoff request can be following form:

Step 2, Main Conference Focus receive that UE1 sends after son conference session handoff request, return the response message of handover success to UE1.

Step 3, UE1 pass through Dialog1 ' and send the conference session content to Main Conference Focus, and this conference session content is the son conference session content.

Step 4, Main Conference Focus return response message to UE1 after receiving the son conference session content of UE1 transmission.Because as the son conference media transmission channel, therefore, Main Conference Focus can know clearly that its session content that receives is the son conference session content to the media transmission channel of this moment temporarily.

Step 5, Main Conference Focus according to son conference attend a meeting user list information, pass through Dialog3 ' and send the son conference session content to UE3.

After step 6, UE3 receive the son conference session content, return response message to Main Conference Focus.

Step 7, Main Conference Focus according to son conference attend a meeting user list information, send the son conference session content by Dialog4 to UE4.

After step 8, UE4 receive the son conference session content, return response message to Main Conference Focus.

Step 9, UE1 are after the son conference speech, wish to return again main conference session state, UE1 sends to main conference session handoff request to Main Conference Focus, the media transmission channel of the son conference session Dialog1 ' between UE1 and the Main Conference Focus is used again the media transmission channel of the conference session Dialog1 that decides with request.

Step 10, Main Conference Focus receive that UE1 sends after main conference session handoff request, return the response message of handover success to UE1.

Step 11, UE1 send the conference session content by Dialog1 to Main Conference Focus, and this conference session content is main conference session content.

Step 12, Main Conference Focus return response message to UE1 after receiving the main conference session content of UE1 transmission.Because the media transmission channel between UE1 and the Main Conference Focus is taken by main meeting at this moment, therefore, Main Conference Focus can know clearly that its conference session content that receives is main conference session content.

Step 13, Main Conference Focus according to main meeting attend a meeting user list, pass through Dialog2 and send main conference session content to UE2.

After step 14, UE2 receive main conference session content, return response message to Main Conference Focus.

Step 15, Main Conference Focus according to main meeting attend a meeting user list, pass through Dialog3 and send main conference session content to UE3.

After step 16, UE3 receive main conference session content, return response message to Main Conference Focus.

Need to prove, in above-mentioned flow process at Fig. 8 is described, the sequencing that on behalf of operation, number of steps carry out, for example, the step 5 among Fig. 8, step 7 can be carried out simultaneously, also can reversed order; Again for example, step 13, step 15 can be carried out simultaneously, also can reversed order.

Accompanying drawing 9 is that main conference session, the son conference session of embodiment two receives control flow chart.

Among Fig. 9, step 1, UE2 send main conference session content by the media transmission channel of Dialog2 to Main Conference Focus.

Step 2, Main Conference Focus return response message to UE2 after receiving the main conference session content of UE2 transmission.

Step 3, UE4 send the son conference session content by the media transmission channel of Dialog4 to Main Conference Focus.

Step 4, Main Conference Focus return response message to UE4 after receiving the son conference session content of UE4 transmission.

Step 5, Main Conference Focus according to main meeting attend a meeting user list information, son conference attend a meeting user list information, pass through the conference session content of Dialog1 after UE1 sends main conference session content, son conference session content audio mixing.

Step 6, UE1 return response message to Main Conference Focus after receiving conference session content behind the audio mixing.

Step 7, Main Conference Focus according to main meeting attend a meeting user list information, son conference attend a meeting user list information, pass through Dialog2 and send main conference session content to UE2.Need to prove, for convenience of description, only show attend a meeting user and use the user that attends a meeting of UE1, UE2 and UE3 to be the main meeting user that attends a meeting of four of using UE1, UE2, UE3, UE4 among Fig. 9, in fact in actual applications, also there is other main meeting user that attends a meeting, therefore, the main conference session content that Main Conference Focus sends to UE2 in step 7 is not the main conference session content that Main Conference Focus receives in step 2 UE2 sends.If three users that attend a meeting that use UE1, UE2, UE3 are only arranged in the main meeting, then step 7 is omissible.

After step 8, UE2 receive main conference session content, return response message to Main Conference Focus.

Step 9, Main Conference Focus according to main meeting attend a meeting user list information, son conference attend a meeting user list information, pass through the conference session content of Dialog3 ' (promptly passing through Dialog3) after UE3 sends main conference session content, son conference session content audio mixing.

Step 10, UE3 return response message to Main Conference Focus after receiving session content behind the audio mixing.

The secret conference session implementation method that the embodiment of the invention is provided describes below.

Attend a meeting and to carry out the transmission of secret conference session content between the user.The secret meeting also can be called " private chat ".The secret meeting is meant in active conference (as main meeting, son conference) to be carried out in the process, some specific meeting privately of attending a meeting between the user.In realizing the secret conference process, do not need to set up conference control center, can not need to distribute new meeting identification yet for the secret meeting; In addition, the secret meeting has the crypticity requirement, and is attached to ongoing meeting, and meeting is attached to main meeting as secret.The user that attends a meeting who carries out the secret meeting can be the main meeting user that attends a meeting, and also can be the son conference user that attends a meeting, can also both comprise main meeting attend a meeting the user, also comprise the son conference user that attends a meeting.

The difference of secret meeting and son conference comprises: son conference can allow the non-main meeting user that attends a meeting to add, and still, usually the secret meeting is defined as the temporary meeting of attending a meeting between the user.

The embodiment of the invention provides following two kinds of modes that realize the secret meeting:

Mode one, utilize the secret conference session to take the user that attends a meeting that the conference session channel request determines need to receive secret conference session content, then, after receiving secret conference session content, the user that attends a meeting who receives secret conference session content to the above-mentioned needs of determining sends secret conference session content.

In mode one, determine the user that attends a meeting that needs receive secret conference session content owing to can take the conference session channel request according to the secret conference session, therefore, attend a meeting the user when follow-up transmission secret conference session content, can no longer carry the user that attends a meeting who needs to receive secret conference session content.Send above-mentioned request the user that attends a meeting and attend a meeting to this during user request switches to main meeting or son conference, the conference control center conference session content that the user sends of this can being attended a meeting all is defined as secret conference session content.

Mode one utilizes existing conference session passage to realize the transmission of secret conference session content, promptly attends a meeting the user after sending above-mentioned request, and the secret conference session takies this existing conference session passage between user and the conference control center of attending a meeting temporarily.

Secret conference session in the mode one takies can carry secret session indication in the conference session channel request, send secret conference session user ID, receive secret conference session user ID.What secret session indication was used to represent to take the conference session passage is the secret conference session.

The specific implementation process of mode one can for: attend a meeting the user before sending secret conference session content, send the secret conference session to conference control center earlier and take existing conference session channel request.This conference control center can be main conference control center or the son conference control centre of describing in the foregoing description one, also can be the conference control center of describing in the foregoing description two of reusing.After conference control center receives this request, represent clearly to know that according to indication of the secret session in this request and transmission secret conference session user the user that attends a meeting of this request of transmission is a secret conference session content in the conference session content of follow-up transmission.Conference control center can clearly be known according to the reception secret conference session user ID of carrying in this request: the user that attends a meeting who needs to receive secret conference session content.The user profile of attending a meeting of the reception secret conference session here can be the user's that attends a meeting information, also can be a plurality of users' that attend a meeting information.Be that secret conference session content can be attended a meeting at two and transmitted between the user, also can between the three or more users of attending a meeting, transmit.Conference control center is after the conference session content that the user that attends a meeting who receives this request of transmission sends, and the user that attends a meeting who receives the secret conference session to the above-mentioned needs of determining sends this secret conference session content.Can not carry the user profile of attending a meeting that needs to receive secret conference session content in the secret conference session content that the user that attends a meeting sends.Certainly, embodiment of the present invention is not got rid of the possibility of the user profile of attending a meeting that carries needs reception secret conference session content in the secret conference session content yet, but, even carry the user profile of attending a meeting that needs to receive secret conference session content in the secret conference session content, conference control center also is to transmit secret conference session content according to the user profile of attending a meeting of carrying in the above-mentioned request.

In mode one, that carries out the secret meeting attends a meeting the user in needs send main conference session perhaps during the son conference session content, the technical scheme that can adopt the foregoing description one or embodiment two to describe realizes, for example, the user that attends a meeting sends the transmission of description in the foregoing description two to son conference session handoff request or to main conference session handoff request to conference control center, then, this user that attends a meeting sends master session conference content or son conference session content to conference control center again.The specific implementation process is not described in detail at this.

Mode two, utilize existing conference session to set up new conference session passage, utilize newly-established conference session passage to realize the transmission of secret conference session content for the secret meeting.

Under secret conference session medium type and existing conference session medium type situation identical or inequality, all can adopt mode two to realize the secret meeting.

Above-mentioned secret conference session passage can be set up by conference control center attending a meeting the user first after conference control center sends information notification of meetings control centre and need carry out the secret meeting.The process of setting up of secret conference session passage can for: when the user that attends a meeting need carry out the secret meeting, the user that attends a meeting can send the request of secret conference session to conference control center, this secret conference session request shows need carry out the secret meeting, can carry the user profile of attending a meeting of participating in the secret meeting in this request, thereby make conference control center can know clearly which user that attends a meeting need carry out the secret meeting, promptly need attend a meeting and set up secret conference session passage between the user itself and which, and secret conference session content need be attended a meeting at which and transmitted between the user.Conference control center is at it and need carry out respectively attending a meeting of secret meeting and set up secret conference session passage between the user respectively.Here need the user that attends a meeting who carries out the secret conference session to be two or more.

After secret conference session passage is successfully set up, because the conference session passage of secret meeting correspondence is the conference session passage of secret conference session special use, therefore, need the user that attends a meeting who sends secret conference session content before sending secret conference session content, not send the secret conference session and to take existing conference session channel request.Conference control center can judge whether the conference session content that receives is secret conference session content by the transmission channel of its conference session content that receives.Conference control center is after judging the conference session content that receives and being secret conference session content, and the user that attends a meeting of other in the secret meeting sends secret conference session content.Here other user that attends a meeting is the user that attends a meeting except that the user that attends a meeting who sends this conference session content in the secret meeting.

The user that attends a meeting can ask to withdraw from the secret conference session.After the secret conference session was withdrawed from the user that attends a meeting request, conference control center can discharge itself and this attend a meeting secret conference session passage between the user.

The 4th control module in first interactive module sends the son conference session content or sends main conference session content and son conference session content to each son conference user that attends a meeting according to the notice of canned data, judge module in second memory module.The 4th control module can send the conference session content to son conference user or the main meeting user that attends a meeting that attends a meeting by the conference session passage shared; The 4th control module also can be passed through independently main conference session passage and send main conference session content and pass through independently that the son conference session channel sends the son conference session content to the user that attends a meeting who participates in son conference to the user that attends a meeting who participates in main meeting.The user that attends a meeting who participates in main meeting, son conference at the same time need receive under the situation of main conference session content and son conference session content, the 4th control module can be with behind the main conference session content that receives, the son conference session content audio mixing, and the user that attends a meeting who receives main conference session content and son conference session content to needs sends.

The user that attends a meeting who participates in main meeting son conference simultaneously can select whether to receive main conference session content, son conference session content, and the user that attends a meeting who participates in main meeting, son conference simultaneously also can select to withdraw from main meeting or withdraw from son conference, at this moment, the 4th control module can send the conference session content of mating with the user's that attends a meeting selection to the user that attends a meeting, thereby makes the user that attends a meeting selectivity receive the conference session content.

In the 4th control module the 3rd receives request module and is used to receive main meeting user, the son conference multiple request that the user sends of attending a meeting of attending a meeting.The 5th control module in the four module can receive the request that request module receives according to the second memory module canned data, the 3rd, send with the user that attends a meeting to the user that attends a meeting and to select the conference session content of mating, exemplify the specific implementation process that several the 5th control modules send the conference session contents below:

Example 1, the 3rd receives request module and receives the son conference main conference session request of reception that the user sends of attending a meeting, and this receives at least one user profile of attending a meeting that carries main meeting identification in the main conference session request or carry main meeting identification and appointment.

In receiving main conference session request, carry main meeting identification, do not carry under the situation of at least one user profile of attending a meeting of appointment, respectively attend a meeting in can the main meeting according to second memory module storage user's the state information of attending a meeting (as the main meeting user list information of attending a meeting) of the 5th control module judges that whether the son conference of the request of the transmission user that attends a meeting is the main meeting user that attends a meeting simultaneously, if be the main meeting user that attends a meeting simultaneously, then send main conference session content to sending this son conference that receives main conference session request user that attends a meeting; If be not the main meeting user that attends a meeting simultaneously, then do not send main conference session content to sending this son conference that receives main conference session request user that attends a meeting.

In receiving main conference session request, carry under the situation of at least one user profile of attending a meeting of main meeting identification and appointment, respectively attend a meeting in can the main meeting according to second memory module storage user's the state information of attending a meeting (as the main meeting user list information of attending a meeting) of the 5th control module judges that whether the meeting of the appointment user that attends a meeting is the main meeting user that attends a meeting simultaneously, if be the main meeting user that attends a meeting simultaneously, then the user that attends a meeting to this appointment sends main conference session content; If be not the main meeting user that attends a meeting simultaneously, then do not send main conference session content to the user that attends a meeting of this appointment.Here need to prove, the user that attends a meeting in appointment is under a plurality of situations, the user is that attend a meeting user, other user that attends a meeting of main meeting is not the main meeting user that attends a meeting if certain of appointment is attended a meeting, then certain user that attends a meeting sends main conference session content to this, and does not send main conference session content to other user that attends a meeting of appointment.

Example 2, the 3rd receives that request module receives that son conference attends a meeting that the user sends stops to receive main conference session request, and this stops to receive at least one user profile of attending a meeting that carries main meeting identification in the main conference session request or carry main meeting identification and appointment.

Carry main meeting identification in the main conference session request, do not carry under the situation of at least one user profile of attending a meeting of appointment stopping to receive, the 5th control module can directly be determined not the user that attends a meeting who stops to receive main conference session request to transmission and send main conference session content, respectively attend a meeting in also can the main meeting according to second memory module storage user's the state information of attending a meeting (as the main meeting user list information of attending a meeting) of the 5th control module is judged the user that attends a meeting, and then is determined to operate.Concrete as the description in the above-mentioned method execution mode.

Stopping to receive under the situation of at least one user profile of attending a meeting that carries main meeting identification and appointment in the main conference session request, the user that attends a meeting that the 5th control module can directly be determined not to appointment sends main conference session content; Respectively attend a meeting in also can the main meeting according to second memory module storage user's the state information of attending a meeting (as the main meeting user list information of attending a meeting) of the 5th control module is judged the user that attends a meeting, and then is determined to operate.Concrete as the description in the above-mentioned method execution mode.

Example 3, the 3rd receives request module and receives the main meeting reception son conference conversation request that the user sends of attending a meeting, and this receives at least one user profile of attending a meeting that carries the son conference sign in the main conference session request or carry son conference sign and appointment.

In receiving the son conference conversation request, carry the son conference sign, do not carry under the situation of at least one user profile of attending a meeting of appointment, respectively attend a meeting in can the son conference according to second memory module storage user's the state information of attending a meeting (as the son conference user list information of attending a meeting) of the 5th control module judges that whether the main meeting of the request of the transmission user that attends a meeting is the son conference user that attends a meeting simultaneously, if be the son conference user that attends a meeting simultaneously, then send the son conference session content to the main meeting that sends this reception son conference conversation request user that attends a meeting; If be not the son conference user that attends a meeting simultaneously, then do not send the son conference session content to the main meeting that sends this reception son conference conversation request user that attends a meeting.

In receiving the son conference conversation request, carry under the situation of at least one user profile of attending a meeting of son conference sign and appointment, respectively attend a meeting in can the son conference according to second memory module storage user's the state information of attending a meeting (as the son conference user list information of attending a meeting) of the 5th control module judges that whether the meeting of the appointment user that attends a meeting is the son conference user that attends a meeting simultaneously, if be the son conference user that attends a meeting simultaneously, then the user that attends a meeting to this appointment sends the son conference session content; If be not the son conference user that attends a meeting simultaneously, then do not send the son conference session content to the user that attends a meeting of this appointment.Here need to prove, the user that attends a meeting in appointment is under a plurality of situations, the user is not the son conference user that attends a meeting for attend a meeting user, other user that attends a meeting of son conference if certain of appointment is attended a meeting, then certain user that attends a meeting sends the son conference session content to this, and does not send the son conference session content to other user that attends a meeting of appointment.

Example 4, the 3rd receives that request module receives that main meeting attends a meeting that the user sends stops to receive the son conference conversation request, and this stops to receive at least one user profile of attending a meeting that carries the son conference sign in the son conference conversation request or carry son conference sign and appointment.

Carry main meeting identification in the son conference conversation request, do not carry under the situation of at least one user profile of attending a meeting of appointment stopping to receive, the 5th control module can directly be determined not the user that attends a meeting who stops to receive the son conference conversation request to transmission and send the son conference session content, respectively attend a meeting in also can the son conference according to second memory module storage user's the state information of attending a meeting (as the son conference user list information of attending a meeting) of the 5th control module is judged the user that attends a meeting, and then is determined to operate.Concrete as the description in the above-mentioned method execution mode.

Under the situation that stops to receive at least one user profile of attending a meeting that carries son conference sign and appointment in the son conference conversation request, the user that attends a meeting that the 5th control module can directly be determined not to appointment sends the son conference session content; Respectively attend a meeting in also can the son conference according to second memory module storage user's the state information of attending a meeting (as the son conference user list information of attending a meeting) of the 5th control module is judged the user that attends a meeting, and then is determined to operate.Concrete as the description in the above-mentioned method execution mode.

Example 5, the 3rd receives request module and receives the main meeting main request for conference that withdraws from that the user sends of attending a meeting, and this withdraws from and carries main meeting identification in the main request for conference.The 5th control module is according to the main meeting identification that carries in the request, and no longer the user that attends a meeting who withdraws from main request for conference to transmission sends main conference session content.The 5th control module can also be upgraded canned data in second memory module according to withdrawing from main request for conference, for example, upgrades the user's that attends a meeting in the main meeting the state of attending a meeting (comprise main meeting attend a meeting user list information).The 5th control module can receive the concrete condition of conference session according to the concrete condition of boss's conference session passage, the user that attends a meeting, judge whether need to discharge to send the conference session between user and the conference control center of attending a meeting that withdraws from main request for conference, and carry out corresponding releasing operation according to judged result, the description in the concrete as above-mentioned method execution mode.

Example 6, the 3rd receives request module and receives the son conference son conference request of withdrawing from that the user sends of attending a meeting, and this withdraws from and carries the son conference sign in the son conference request.The 5th control module is according to the son conference sign of carrying in the request, and no longer the user that attends a meeting who withdraws from the son conference request to transmission sends the son conference session content.The 5th control module can also be upgraded canned data in second memory module according to withdrawing from the son conference request, for example, upgrades the user's that attends a meeting in the son conference the state of attending a meeting (comprise son conference attend a meeting user list information).The 5th control module can receive the concrete condition of conference session according to the concrete condition of boss's conference session passage, the user that attends a meeting, judge whether need to discharge to send the conference session between user and the conference control center of attending a meeting that withdraws from the son conference request, and carry out corresponding releasing operation according to judged result, the description in the concrete as above-mentioned method execution mode.

After having briefly introduced judge module differentiation conference session content to exemplify mode, reaching the mutual specific implementation process of first interactive module realization session content, describe below second and stop the module and second release module.

Second stops module is arranged in the Conference server, after the conference control center of successfully setting up main meeting, belongs to this conference control center side.Second stops module after judging the main meeting of needs termination, notifies second release module, and stop main meeting after second release module discharges each conference session.Second stop module can the 3rd receive request module receive withdraw from main request for conference after, judging whether needs to stop main meeting, as judges whether also have the main meeting user that attends a meeting in the main meeting, the description in the concrete as above-mentioned method execution mode.

Second release module is arranged in the Conference server, after the conference control center of successfully setting up main meeting, belongs to this conference control center side.Second release module receive second stop the notice of module after, send the son conference request of withdrawing from respectively to each son conference user that attends a meeting, discharge attend a meeting conference session between the user of conference control center and boss's meeting.Second release module notifies second to stop module after successfully discharging conference session.

The terminal equipment that embodiment of the present invention is provided describes below.

The terminal equipment that embodiment of the present invention provides comprises that session sets up the module and second interactive module.Second interactive module can comprise: any one in the first transmission control module, the second transmission control module and the reception control module or a plurality of arbitrarily.

The conference session between module foundation and the conference control center is set up in session.For example, when the user need participate in main meeting, the session in the terminal equipment set up module by and Conference server between information interaction set up conference session between this user and the conference control center.Again for example, when the user does not participate in that request participates in son conference under the situation of main meeting, the session in the terminal equipment set up module by and Conference server between information interaction set up conference session between this user and the conference control center.

Second interactive module utilizes session to set up the conference control center that module sets up and attend a meeting conference session and conference control center interactive conference session content between the user.Second interactive module can be controlled the state of this conference session, for example, and when the user that attends a meeting participates in main meeting, second interactive module is controlled this conference session with the conference session of deciding, again for example, when the user that attends a meeting participated in son conference, second interactive module was controlled this conference session as the son conference session.

The aforesaid operations of second interactive module can be realized: do not possess at terminal equipment under the situation of parallel session ability, use the user that attends a meeting of terminal equipment can participate in main meeting and son conference simultaneously.

Terminal equipment can send main conference session content, son conference session content to conference control center by following dual mode.

Mode one, first sends control module and sends the transmission conference session request that carries meeting identification to conference control center, then, sends the conference session content corresponding with this meeting identification to conference control center again.For example, first sends control module sends the conference session request to the conference control center transmission, carry main meeting identification in this request, first sends control module after terminal equipment receives the response message that conference control center returns, and sends main conference session content to conference control center.The process and the said process of the first transmission control module transmission son conference session content are similar, no longer illustrate at this.

Mode two, second sends control module and sends the conference session content that carries meeting identification to conference control center.For example, second sends control module sends the main conference session content that carries main meeting identification to conference control center, perhaps second sends control module carries son conference session content from the son conference sign to the conference control center transmission.

Receive control module and can send multiple request, so that terminal equipment receives the conference session content that it needs to conference control center.For example, receive control module and can send any one or a plurality of request in the following request: receive main conference session request, receive the son conference conversation request, stop to receive main conference session request, stop to receive the son conference conversation request, withdraw from main request for conference, withdraw from the son conference request to conference control center.Can carry meeting identification in above-mentioned each request, also can carry at least one user that attends a meeting of meeting identification and appointment.Concrete as the description in the above-mentioned method execution mode.

Two kinds of secret meeting implement devices that embodiment of the present invention is provided describe below.

Wherein a kind of secret meeting implement device comprises that the 4th receives request module and the 6th control module, and this secret meeting implement device can be arranged in the Conference server.

The 4th receives request module receives the secret conference session that the user that attends a meeting sends and takies the conference session channel request.The secret conference session takies can carry secret session indication in the conference session channel request, send secret conference session user ID, receive secret conference session user ID.What secret session indication was used to represent to take the conference session passage is the secret conference session.The 4th receives request module after receiving above-mentioned request, and the secret conference session takies this existing conference session passage between user and the conference control center of attending a meeting temporarily.

The 6th control module can take information that the conference session channel request carries according to the secret conference session and determine the user that attends a meeting that needs send secret conference session content, the user that attends a meeting that needs receive secret conference session content.The conference session content of the follow-up transmission of user of attending a meeting that the 6th control module can be represented transmission secret conference session user ID is defined as secret conference session content, and the user that attends a meeting who represents up to transmission secret conference session user ID switches to main meeting or son conference.In this embodiment, can not carry the user profile of attending a meeting that receives secret conference session content in the secret conference session content that the user that attends a meeting sends, concrete as the description in the above-mentioned method execution mode.

Another kind of secret meeting implement device comprises the 5th reception request module, sets up session channel module and the 6th control module.This secret meeting implement device can be arranged in the Conference server.This secret meeting implement device utilizes existing conference session to set up new conference session passage for the secret meeting, utilizes newly-established conference session passage to realize the transmission of secret conference session content.

The 5th receives request module receives the secret conference session request that the user that attends a meeting sends.The request of secret conference session shows need carry out the secret meeting, and this request can be carried the user profile of attending a meeting of participating in the secret meeting.

Set up the session channel module and can know clearly that according to the request of secret conference session which user's needs of attending a meeting carries out the secret meeting, promptly need attend a meeting and set up secret conference session passage between the user itself and which.Set up the session channel module in conference control center and need carry out respectively attending a meeting of secret meeting and set up secret conference session passage between the user respectively.

The transmission channel of the conference session content that the 7th control module can receive by conference control center judges whether the conference session content that conference control center receives is secret conference session content, the 7th control module is after judging the conference session content that receives and being secret conference session content, and the user that attends a meeting of other in the secret meeting sends secret conference session content.Here other user that attends a meeting is the user that attends a meeting except that the user that attends a meeting who sends this conference session content in the secret meeting.
