FIG. 3 is a second flowchart of the terminal dialing into the conference in the present invention. The best way to implement the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

In order to achieve the object of the invention, two special service numbers should be preset in the method proposed by the present invention: initiating a conference special service number and joining a conference special service number, both of which are used as terminal dialing prefixes for notification Point server dialing purpose. The method proposed by the present invention includes two steps of a terminal dialing initiation conference process and a terminal dialing joining conference process. The process of the terminal dialing initiation conference is as shown in FIG. 1:

Step 110: The calling terminal prefixes the parameter number of the meeting capacity and the conference password with the prefix of the “initiating conference special service number”, initiates a dialing operation, and sends a request to create a conference to the registration server. The dialing string starts with the "Initiation of the conference service number". It includes the parameters such as the capacity, password, duration, quality of service, and the terminal that is invited to join the conference. The conference capacity and password in the parameter information are mandatory. Others are Optional; the parameter string is a string identifier that conforms to the e.164 specification.

Step 120: The registration server performs a fund inquiry to the billing system, and if the calling terminal account has sufficient funds, the meeting is allowed, otherwise the party refuses.

Step 130: The registration server authenticates the calling terminal to confirm whether the terminal has the right to convene the conference. After the authentication is passed, the conference request is forwarded to the multipoint control unit, otherwise the conference request is rejected.

Step 140: After receiving the request, the multipoint control unit locally creates a conference, reserves a corresponding resource according to the conference capacity, allocates a conference number for the conference, and registers the conference number with the registration server. The assigned conference number can be in the form of "join conference service number + calling terminal number". Step 150: The multipoint control unit sends feedback to the calling terminal, returns the conference number, confirms that the conference is successfully called, and initiates a call to the calling terminal and other participating terminals, and the conference is called.

The process of dialing a terminal to join a conference is shown in Figure 2:

Step 210: The calling terminal prefixes the parameter number of the conference terminal and the conference password with a prefix of “joining the conference service number”, initiates a dialing operation, and sends a call request to the registration server.

Step 220: The registration server authenticates the calling terminal, confirms whether the terminal has the right to join the conference, determines whether the joined conference has been registered after the authentication is passed, and returns a multipoint server address to the calling terminal if the registration is already performed, otherwise rejects the call. request.

Step 230: The calling terminal initiates a call to the multipoint server according to the address fed back by the registration server, where the call information includes the joined conference number and the conference password.

Step 240: The multipoint server performs joint authentication on the conference number and the conference password, and allows the calling terminal to join the conference after the authentication is passed, otherwise refuses to join the conference.

Further, step 240 may further include step 250: after the authentication is passed, the multipoint server determines whether the conference capacity is full, directly responds to the call if there is idle, and allows the calling terminal to join the conference; if the capacity is full, apply for a new resource, If the system still has idle resources to allow the application, the call is allowed to join the conference in response to the call; otherwise the call request is rejected.

The process of dialing a terminal to join a conference is shown in Figure 3:

Step 310: Join the conference terminal dialing call "Join the conference service number" to place a call request to the registration server. In this case, the multipoint control unit has already registered the terminal in the already held conference. Therefore, when joining the terminal to make a call request, only the "joining special service number" is required. The registration method may be that the multipoint conference unit completes the conference configuration and the number configuration of the joining terminal in advance, or the terminal that initiates the conference invites the terminal when calling.

Step 320: The registration server performs authentication authentication on the calling terminal. After the authentication is passed, it is determined that the number of the terminal call is “joining the conference special service number”, and then directly returns the address of the multi-point control unit, otherwise the access is refused.

Step 330: The calling terminal initiates a call to the multipoint control unit according to the address fed back by the registration server. Step 340: The multipoint control unit checks whether the terminal number has been registered in the currently held conference, and if yes, joins the terminal directly to the conference, otherwise refuses to join the conference.

The terminal dialing initiation conference process described above can be used independently. Terminal dialing to join the meeting process needs To be used on the basis of the terminal dialing initiation meeting. The process of dialing a terminal to join a conference includes but is not limited to the above two.

The following is specifically described in conjunction with a specific application example.

First, the terminal dials to initiate a meeting

(1) Set "Initiate Conference Special Service Number" to 980;

(2) Set the "Terminal Dialing Initiating Conference" dialing rule: "Initiate the conference special service number + conference template number * called number, called number n** capacity * password * duration;

A) "Initiating a conference special service number" means that this call wishes to call a conference;

B) "Meeting Template Number" refers to the conference attribute that you want to hold. This is a set of conference templates preset by the system, which contains some basic requirements of the conference, such as conference quality settings, etc., which are used to provide users with quick choices;

0 multiple "called numbers" indicate other terminals that need to be invited to join the conference; the content is optional. After entering the called number, it is hoped that the conference will actively invite the called number after the conference is held; the user can also after the conference is held. Through the implementation of the "terminal dialing number to join the conference" to actively dial into the conference; D) "capacity" indicates how many people are allowed to participate in the conference, the parameter is optional, if you select this parameter when dialing, the system will reserve enough The resource ensures that the terminal within the capacity range can join the conference; if the capacity parameter is not selected, it means that there is no need to reserve resources, and the system will try to have enough resources as long as there are idle resources;

E) "Password" is information that needs to be input by the user. This password is used to authenticate the participating terminals, ensuring that unrelated personnel cannot join the meeting at will;

F) "Time" is in minutes, optional parameters. If selected, the system will ensure that the system is available within the selected time. If not selected, the system provides the default time period for the conference. The timeout can be extended, as long as the system resources are idle. The system will try to satisfy;

G) "#" is the terminator for the end of the terminal device without the "Dial" button. (3) The specific implementation process of the "terminal dialing initiation conference" function based on the H.323 protocol:

A) the terminal that initiates the dialing, loads the dialing information in the destination address parameter of the call request message, and sends it to the registration server;

B) The registration server first queries the billing server for user funds, and if the funds are sufficient, transfers the dial information to the multipoint processing unit.

C) The multi-point processing unit parses the information of the called number field, and finds that it is "initiating the conference special service number" At the beginning, the conference creation work is performed, and the number of the conference is made in the form of "980 + Initiating Conference Terminal Number", and the number is registered with the registration server;

D) After the multi-point processing unit conference is successfully created, the success information is fed back to the registration server, and the registration server feeds back the call confirmation message to the terminal that initiated the dialing, and simultaneously informs the address of the multi-point processing unit of the terminal that initiated the dialing, and the terminal that initiates the dialing will continue to follow. The call flow actively joins the conference; the multi-point processing unit actively initiates the process of calling the terminal according to the information of the called number included in the dialing information. The above process is a standard H.323 call flow.

"Terminal Dial-Initiation Conference" Dialing Example:

980*0755001*0755002**6*888888*120#

Create a conference. After the conference is created, invite the terminal 0755001, 0755002 to join the conference. Use the default conference template, capacity 6, password 888888, and the duration is 120 minutes.

980101**4*123456*60#

- Create a conference, use conference template 101, duration 60 minutes, password 123456, capacity 4. 2. The terminal dials the calling number to join the conference.

(1) Set the "Join Meeting Special Service Number" to 990;

(2) Set the "Terminal dialing number to join the conference" dialing rules: "Join the conference service number + calling number * conference password #";

A) "Join the conference special service number" means that the dialing is to join a conference;

B) "Calling number" refers to the number of the terminal that initiated the meeting, and the call joins the meeting initiated by the terminal;

C) "Meeting Password" is the password that was set when the meeting was created.

(3) The specific implementation process of the function of "terminal dialing the calling number to join the conference" based on the H.323 protocol: A) the terminal that initiates the dialing, loads the dialing information in the destination address parameter of the call request message, and sends it to the registration server;

B) The registration server determines whether the "980+calling number" information has been registered, if not registered, rejects the current call; if it has already been registered, notifies the dialing terminal of the address of the multipoint processing unit;

C) if the dialing terminal receives the address of the multipoint processing unit, initiates a call to the multipoint processing unit, and loads the dialing information in the destination address parameter of the call setup message;

D) The multi-point processing unit receives the call setup message, parses the content of the destination address parameter of the message, determines the conference that the call wishes to join, and then determines whether the password in the dialing information is correct, if the password is authenticated If yes, the callback port L|establishment success message is sent back, otherwise the call setup rejection message is sent back. The above process is a standard H323 call flow.

"Terminal dialing master 3 M number joins the conference" dialing example:

9900755001 t=888888#

—— Join the conference initiated by the terminal 0755001, the conference password is 888888;

Third, the terminal dials the calling number to join the conference.

(1) Set the "Join Meeting Special Service Number" to 990;

(2) Set the static address resolution relationship on the registration server: Resolve 990 to the address of the multipoint control unit.

(3) The specific implementation process of the function of "terminal dialing the calling number to join the conference" based on the H.323 protocol:

A) The terminal dialing call "990" is sent to the registration server;

B) The registration server first searches for a "990" in the static address resolution table, and if so, returns the address of the multipoint control unit directly to the terminal according to the static address resolution table; if not, rejects the current call;

C) the dialing terminal, if the address of the multipoint processing unit is received, the call is initiated to the multipoint processing unit;

D) The multipoint control unit checks whether the terminal number has been registered in the currently held conference, and if so, joins the terminal directly to the conference, otherwise refuses to join the conference.

"Terminal dialing the calling number to join the conference" dialing example:

990#

- The terminal directly calls 990# to join the conference;
