Step S304, it is InActive (non-use attitude) that the CONF module continues to send out the IMS conference medium that request is provided with A to the RM module;
Step S306, the CONF module continues to send out request to the RM module, the IMS conference medium of application B; The IMS conference medium that B is set is RecvOnly (receiving only attitude); After receiving the IMS conference medium of B, send out message informing B switching media to the meeting medium to B;
Step S308, the CONF module continues to send out request to the RM module, puts stand by tone to meeting; Each user can hear the meeting stand by tone in meeting this moment;
Step S310, the CONF module is put dialing tone to the party A-subscriber and is continued to collect the digits;
Step S312, the party A-subscriber listens dialing tone, dials the number of user C.A and C enter conversation state;
Step S314, party A-subscriber in user C communication process, hooking, the CONF module continues to send out request to the RM module, the IMS conference medium of application user C;
Step S316, the party A-subscriber listens dialing tone, and the party A-subscriber can continue to add the user in meeting; Repeating step S312 is to step S314;
Step S314 has a meeting if desired, and the party A-subscriber dials the meeting access code, and number analysis is a meeting.
The CONF module is sent out message successively and is stopped stand by tone for the RM module; The CONF module is sent out message successively and is given the RM module, and the IMS conference medium connection attribute of revising each called subscriber is SendRecv (a transmitting-receiving attitude), and the distant end media of change conference initiator A is meeting, and this IMS conference medium pattern is revised as SendRecv (transmitting-receiving attitude) equally; Enter meeting this moment.
Fig. 4 shows the treatment step that continues to add the access customer meeting according to the embodiment of the invention.
As shown in Figure 4, comprise step S320, will add other users in the meeting, then A hooking, execution in step S304, step S308, step S310 at this moment.The party A-subscriber listens dialing tone, and other users listen the meeting stand by tone; A dials new user's number, enters conversation; Execution in step S318 then will have a meeting.
Fig. 5 shows the treatment step according to deletion user D in the meeting of the embodiment of the invention.
As shown in Figure 5, comprise step S312, will delete certain user X in the meeting, then A hooking, execution in step S304, step S308, step S310 at this moment.The party A-subscriber listens dialing tone, and other users listen the meeting stand by tone; A dials deletion user access code+Subscriber Number X, and CONF module notice RM module discharges the IMS conference medium of user X; Send out release message for user X; The CONF module puts busy tone for user A; Wait for that user A hooking recovers meeting.Fig. 6 shows the treatment step of conversing separately with user D according in the meeting of the embodiment of the invention.
As shown in Figure 6, step S324 will converse separately with certain user X in the meeting, then A hooking, execution in step S304, step S308, step S310 at this moment.The party A-subscriber listens dialing tone, and other users listen the meeting stand by tone; A dials independent conversation access code+Subscriber Number X, and the IMS conference medium that CONF module notice RM module is revised user X is InActive; It is party A-subscriber's medium that the CONF module switches called medium for user X; It is the X user media that the CONF module switches called medium for user A; A and X enter conversation; If withdraw from conversation, and the A hooking, the IMS conference medium that CONF module notice RM module is revised user X is RecvOnly (receiving only attitude); Execution in step S310.
Fig. 7 shows the treatment step that discharges flow process according to the meeting of the embodiment of the invention.
As shown in Figure 7, comprise step S326, chairman's on-hook discharges, and then CONF module notice RM module discharges each called IMS conference medium, chairman's IMS conference medium successively.Call release.
Fig. 8 shows the process chart according to the resource management module of the embodiment of the invention.
Step S802, the RM module is received the request of application IMS conference medium, the type of difference media server sends out the request of application IMS conference medium for the medium adaptation layer of MCS for respectively the inside story of different-format; If the SIP media server will be sent out INFO and add processes such as meeting and modification meeting for media server message through an INVITE to media server request IMS conference medium; If type of media server H.248, the message of then sending out ADD adds IMS conference medium, the meeting of MODIFY message modification to the media server request;
Step S804, the RM module is received the request of deletion IMS conference medium, the type of difference media server sends out the request of deletion IMS conference medium for the medium adaptation layer of MCS for respectively the inside story of different-format; If the SIP media server then will be deleted IMS conference medium to media server through sending BYTE; If type of media server is H.248 then sent out SUB message and is deleted IMS conference medium to media server.
In the present invention, the special flow process of dissimilar IMS conference medium servers can be separated with the processing of conference flow, and by the terminal use being disposed specific media server, the media server of available employing various protocols is realized professional; Improved the MCS in the enterprise network (multimedia communications system) and can use dissimilar media servers according to user's actual disposition demand, increased the compatibility of MCS realization conference system, reduced the MCS system for the requirement of convention business to media server is provided, also can realize simultaneously the Hot Spare of special-shaped media server, can switch to fast on the other types media server in case certain media server breaks down, realize that function continues the purpose of using.
In sum, the present invention mainly is on the basis of MCS equipment, directly utilize the existing processing of BCM basic call subsystem, by increasing CONF meeting processing module and in the RM Resource Manager Subsystem, increasing IMS conference medium resource management software process, realize a kind of MCS convention business of compliant with various protocols IMS conference medium server on the function.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
