The identifier of the communication session is a general reference, which may be characteristic information of the call signaling, such as Cal l lD in the SIP message.

Since the communication session has been established between the terminal and the conference server before the HTTP request message is sent, the conference server can obtain the identification information of the terminal. According to an optional implementation form, the HTTP request message sent by the terminal to the conference server may carry the identifier information of the terminal, so that the conference server associates the HTTP session with the communication session according to the identifier information of the terminal. That is, the authority of the HTTP session is determined according to the authority of the communication session.

The identification information of the terminal includes but is not limited to the number of the terminal.

The invention is not limited to the identifier of the communication session or the identifier information of the terminal, and may carry other information, as long as the communication session established between the terminal and the conference server can be identified, so that the HTTP session and the communication session can be associated. There is no limit to this.

Step 150: The terminal accesses the conference control WEB interface according to the HTTP session, and performs a conference control operation.

According to the method provided by the embodiment of the present invention, the terminal not only establishes a communication session with the conference server, but also establishes an HTTP session based on the communication session.

Based on the embodiment of the present invention, the user does not need to define a series of complicated interfaces between the terminal and the conference server, so that the user can perform the conference control operation through the terminal.

There is no need to develop a conference control client on the terminal side. Therefore, there is no need to define any conference control interface between the terminal and the conference server. Only the terminal needs to follow the same mechanism and the conference server for authentication, and the conference control can be accessed. WEB interface. The conference control function does not require private extension of the signaling protocol.

Moreover, in the method provided by the embodiment of the present invention, the user can participate in the conference through the terminal, and can control the conference without adding another device (such as a PC computer) to perform the conference control operation. The embodiment of the invention further provides a method for implementing conference control. The following is described in detail with reference to FIG. 1B: Step 101: Establish a communication session between the conference server and the terminal.

The communication session includes, but is not limited to, a SIP session or an H.323 session.

Step 102: Receive a request message in a session sent by the terminal based on the communication session, where the request message is used to request, by the conference server, access information of a conference control WEB interface.

Optionally, the request message in the session includes but is not limited to an intra-session SIP request message or an intra-session H.323 request message.

Step 103: Send a response message to the terminal, where the response message carries the access information of the conference control WEB interface, so that the terminal sends an HTTP request to the conference server according to the access information of the conference control WEB interface. Message

Specifically, the conference controls access information of the WEB interface, and may include, for example, an HTTP URL.

Optionally, the authentication information may include information such as a conference identifier (ID), a conference password, a token, and the like. Of course, the authentication information can also be different according to the specific implementation of the other party's conference system. For example, some conference systems use the conference ID as a number that can be dialed directly. The authentication information at this time only needs to include the conference password.

Optionally, the response message may further carry an identifier of the communication session, where the identifier of the communication session is used to identify a communication session established between the conference server and the terminal.

Step 104: The conference server receives an HTTP request message sent by the terminal, and establishes an HTTP session with the terminal.

Optionally, if the response message in the foregoing step further carries the authentication information of the conference control WEB interface, the HTTP request message in the step may also carry the authentication information of the conference control WEB interface, so that the terminal according to the conference The authentication information of the WEB interface is controlled, and the authentication of the conference server is requested. The conference server controls the authentication information of the WEB interface according to the conference, authenticates the HTTP request message, and passes the authentication. An HTTP request message, establishing an HTTP session with the terminal.

Optionally, if the response message carries the identifier of the communication session, the HTTP request message may further carry the identifier of the communication session, and the conference server sends the HTTP session according to the identifier of the communication session. Associated with the communication session.

The identifier of the communication session is a general term, which may be characteristic information of call signaling, such as in a SIP message.

Cal l lD and so on.

Since the communication session has been established between the conference server and the terminal before the HTTP request message is sent, the conference server can learn the identification information of the terminal. According to an optional implementation manner, the HTTP request message sent by the terminal to the conference server may carry the identifier information of the terminal, and the conference server associates the HTTP session with the communication session according to the identifier information of the terminal.

According to the method provided by the embodiment of the present invention, the conference server not only establishes a communication session with the terminal, but also establishes an HTTP session based on the communication session. The terminal accesses the conference control WEB interface according to the established HTTP session, and performs conference control operations. The embodiment of the present invention adopts a technology similar to B/S (Browser/Server) and is a thin client solution. Based on the embodiment of the present invention, the user does not need to define a series of complicated interfaces between the terminal and the conference server, so that the user can perform the conference control operation through the terminal.

There is no need to develop a conference control client on the terminal side. Therefore, there is no need to define any conference control interface between the terminal and the conference server. The terminal only needs to follow the same mechanism and the conference server for authentication, and can access the WEB interface controlled by the conference. The conference control function does not require private extension of the signaling protocol.

Moreover, in the method provided by the embodiment of the present invention, the user can participate in the conference through the terminal, and can also participate in the conference. Control, no need to add other devices (such as PC) for conference control operations. In the following, another embodiment of a method for implementing conference control by a terminal will be specifically described with reference to FIG.

Take the communication session as a SIP session as an example:

A typical enrollment process is as follows: The user dials the conference access number and connects to the phone. Enter the conference ID and conference password according to the voice prompt of the conference server. After the authentication succeeds, join the conference.

In another embodiment of the present invention, the conference server may also initiate a SIP call to the participant terminal. A typical business process is: The conference host invites a participant through the conference control interface. The conference system automatically initiates a SIP call to the participant. The participant can go to the conference by going off-hook.

204. The terminal initiates a communication session request to the conference server and establishes a communication session.

The terminal and the conference server exchange media streams, and the participant successfully joins the conference. Based on the password entered by the participant (meeting moderator password or meeting guest password), the meeting server can confirm the role of the participant (meeting moderator or meeting guest).

At this point, a communication session is established between the terminal and the conference server.

206. The terminal sends an intra-session SIP request message to the conference server according to the communication session, requesting to obtain access information of the conference control WEB interface. Intra-session SIP request messages, such as INFO messages, MESSAGE messages, are of course not limited to this, and other intra-session SIP request messages are also possible. The SIP request message is used to indicate to the conference server that the terminal needs to access the conference control WEB interface.

208. The conference server sends a SIP response message to the terminal, where the SIP response message carries the conference control.

Access information of the WEB interface.

210. After receiving the SIP response message, the terminal parses and obtains the access information of the conference control WEB interface. The HTTP request message is sent to the conference server according to the obtained access control information of the conference control WEB interface.

212. After receiving the HTTP request message of the terminal, the conference server authenticates the HTTP request message, and after the authentication is passed, establishes an HTTP session with the terminal.

And the HTTP session is associated with the communication session that has been created, that is, the authority of the HTTP session is determined according to the permission of the communication session (the conference host or the conference guest).

214. The terminal requests to access the conference control WEB interface according to the established HTTP session.

In another embodiment, steps 210 and 214 may also be performed in combination. That is, the terminal sends an HTTP request message to the conference server according to the obtained access control information of the conference control WEB interface, and requests access to the conference control WEB interface. 216. The conference server returns a conference control WEB interface to the terminal.

The participant is the conference host and returns to the conference host operation interface. The participant is the conference guest and returns to the conference guest operation interface.

If the authority of the communication session is the conference chairperson authority, the authority of the HTTP session is also the conference chairperson authority, and the conference server returns to the terminal a conference control WEB interface capable of controlling the entire conference; if the communication session permission is the conference guest authority, the HTTP session The privilege is also the conference guest privilege, and the conference server returns to the terminal a conference control WEB interface capable of controlling the communication session.

218. The terminal presents the conference control WEB interface to the user (for example, opens a browser window), and the user can perform related operations of the conference control based on the WEB interface.

Through the above process, the terminal not only establishes a communication session with the conference server, but also establishes an HTTP session based on the communication session. The terminal accesses the conference control WEB interface according to the established HTTP session, and performs conference control operations. The embodiment of the present invention adopts a technology similar to B/S (Browser/Server) and is a thin client solution. Based on the embodiment of the present invention, a series of complicated interfaces are not required between the terminal and the conference server, so that the user can perform conference control operations through the terminal.

Moreover, the conference control function is implemented and provided by the conference server, and is loosely coupled with the terminal. When the conference system adds and modifies the conference control function, the participant can access the latest conference control function through the browser of the terminal. The terminal does not need to be developed synchronously, and does not need to upgrade the version or install the patch, which greatly improves the conference system. Maintainability.

Further, since the conference control function is independent of the specific implementation of the terminal, the terminals of different vendors and the conference server can be connected to each other and implement the conference control function.

The conference server provides the conference host operation page and the conference guest operation page according to the rights of the participants. The conference host can control the entire conference. Because the conference call and the HTTP session are associated, the conference guest can also control the conference call. , implement the application to speak, mute/unmute yourself, select the participant's video, apply for the host's permission, etc.

After the terminal sends an HTTP request message to the conference server, the conference server authenticates the HTTP request message, and after the authentication is passed, establishes an HTTP session with the terminal. Equivalent to the terminal has been "WEB login". Therefore the HTTP operation request of step 404 is trusted. In a specific embodiment, for example, the conference server creates an HTTP session after the authentication is passed.

(Session), a unique session ID is generated and returned to the user's browser (such as SARAFI). This session ID is not visible to the user. The user's browser carries the session identifier in each HTTP operation request (for example, the user performs a conference control operation) in the HTTP session, and the conference server determines whether the HTTP operation request is trusted according to the session identifier.

If the user logs out or the access timeout occurs, the conference server clears the session (delete the session ID). The user can not get the trust of the conference server through the HTTP operation request sent by the browser. The conference server usually goes to the login page and asks the user to log in again.

406. The conference server acquires an associated communication session according to the HTTP session.

408. The conference server processes the communication session, participates in the communication session of the participant, and the other participants can hear the voice of the participant.

410. The conference server returns the result of the successful operation to the terminal and refreshes the interface ( refreshing the status of the participant). 412.
