Embodiment

For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.

In speech control procedure of the present invention, certain user terminal can add the additional information of self in the speech control messages, so that self information is sent to the webserver and/or other user terminal by the speech control messages, make the webserver and/or other user terminal that receive the speech control messages can resolve and obtain additional information, thereby the speech operation to the user terminal that initiates a message has further understanding, and the additional information that user terminal is sent is called user profile.Two user terminal A and B are arranged in the supposing the system, and for the purpose of distinguishing, the user profile that user terminal A can be sent is called first additional information, and the user profile that user terminal B sends is called the 4th additional information.

The webserver also can add the additional information of self in the speech control messages, so that self information is sent to all user terminals by the speech control messages, make all user terminals can resolve and obtain additional information, thereby the system operation of the webserver is had further understanding.In addition, the webserver can send to other user terminal as additional information according to the user profile that certain user terminal that conversation strategy receives self is sent, and perhaps according to preset strategy contents such as advertisement is sent to any or all user terminals.In the following description, the additional information that the webserver is sent is called system information.Similarly, two user terminal A and B are arranged in the supposing the system, for the purpose of distinguishing, the system information that the webserver can be issued user terminal A is called second additional information, and the system information that the webserver is issued user terminal B is called the 3rd additional information.

In the prior art, described speech control messages can adopt multiple mode to realize, such as speech control protocol (TBCP, Talk Burst Control Protocol) message and binary message etc.

A kind of preferable TBCP message format that carries additional information comprises existing TBCP content and these two parts of additional information as shown in Figure 2.Wherein, existing TBCP content is the part that the TBCP agreement provides.The additional information transmission of can encoding also can not treatedly directly be attached in the TBCP message and sends.Based on above consideration, additional information should comprise information type and these two parts of the information content.It is coding or noncoded information (NCI) that information type is used to indicate this information.

If information type is a coded message, just directly carry the content behind the coding.If information type is a noncoded information (NCI), also comprise segmentation indication, the indication of end section and Length Indication etc.Wherein, segmentation indication is used for the flag information content and is sent by segmentation in that additional information is long when needing segmentation to send; End section indication is the sign that is arranged on the end section when segmentation sends, and is used to indicate the additional information of this transmission to finish.Adopt the maximum length of which kind of coding and noncoded information (NCI) content to be provided with flexibly as required by operator.The additional information of carrying in the speech control messages can only comprise coded message and encoded content, perhaps only comprises noncoded information (NCI) and non-encoded content.Consider the problem of efficiency of transmission, the general mode of coding and non-coded combination that adopts is as shown in Figure 2 carried additional information.In the practical application, the additional information of being carried by TBCP message can be a text message, such as URL etc., so that the user reads.

Form and Fig. 2 of carrying additional information by binary message are similar, do not give unnecessary details herein.

To describe in detail below by the various speech control flows of execution, and in the speech control messages of flow process, carry additional information, realize the method that additional information is transmitted.Having a plurality of user terminals in actual communication systems, is that example is illustrated with two user terminals only in the following flow process.For the purpose of distinguishing, these two user terminals are called user terminal A and user terminal B, also are first user terminal and second user terminal.

Embodiment one,

What Fig. 3 showed is the processing procedure that user terminal A is sent speaking request and obtained the floor, and specifically may further comprise the steps:

Step 301, a PoC user use the user terminal A Edit Profile, and by speaking request message user profile are sent to the local access server A of PoC.

In this step, the user profile of carrying in the speaking request message comprises contents such as speech theme, speech reason.

After step 302, the local access server A of PoC receive speaking request message, user profile is wherein handled, and speaking request message is sent to PoC centralized control server according to result.

In this step, operator can generate strategy at the local access server A of PoC and handle the user profile of carrying in the speaking request message, such as user profile is deleted or revised, perhaps a part of content in the limited subscriber information sends to PoC centralized control server, or increases operator's information etc. in user profile.Through after the above-mentioned processing, the user profile that the local access server A of PoC sends to PoC centralized control server, the user profile that the user terminal A that receives with the local access server A of PoC is sent is different.

The local access server A of PoC also can not carry out any operation, the speaking request message of carrying user profile that direct transparent transmission receives.

After step 303, PoC centralized control server received speaking request message, whether judgement authorized user terminal A with right to speak, and according to the user profile in the strategy processing speaking request message of operator's setting.

In the practical application, user terminal A need not the local access server A through PoC, just can directly send speaking request message to PoC centralized control server, promptly need not execution in step 302.

Step 304, PoC centralized control server are given user terminal A with right to speak, and carry system information according to conversation strategy in the speech acknowledge message and send to user terminal A.

Described system information comprises contents such as speech holding time.PoC centralized control server can generate the system information that sends to user terminal A according to the strategy of conversation strategy or operator's setting.

Step 305, PoC centralized control server send the speech notification message by the local access server B of PoC to other user terminals such as user terminal B, carry user profile and system information, inform that user terminal B receives the Media Stream that user terminal A sends, user terminal B parses user profile from the speech notification message that receives and system information is shown to self user, and flow process finishes.

In this step, the user profile that PoC centralized control server can be sent user terminal A according to conversation strategy sends to other user terminals such as user terminal B as the part of additional information.

In addition, operator can generate strategy at the local access server B of PoC and handle the user profile and the system information of carrying in the speaking request message, and the described method of processing method and step 302 is similar, no longer encyclopaedizes herein.

When the right to speak of PoC system is in idle condition, adopt speech control protocol (TBCP, TalkBurst Control Protocol) to realize instantiation such as Fig. 4 of processing procedure shown in Figure 3, may further comprise the steps:

Step 401, a PoC user press the PoC button that is arranged on user terminal A, and user terminal A is sent the Talk Burst request (Talk Burst Request) of carrying user profile such as speech theme to the local access server A of PoC.After the local access server A of PoC receives Talk Burst request, user profile is wherein handled, and in Talk Burst request, carried user profile according to result and send to PoC centralized control server.

In this step, the method for the local access server A of PoC process user information is identical with step 302.

Step 402, because the current Idle state that is in of right to speak, PoC centralized control server sends Talk Burst affirmation response (Talk Burst Confirm Responce) by the local access server A of PoC and gives user terminal A, and right to speak is distributed to user terminal A.In addition, the strategy that PoC centralized control server also will be set according to operator is handled the user profile of carrying in the Talk Burst request.

System informations such as speech holding time are carried in described Talk Burst affirmation response, after user terminal A receives Talk Burst affirmation response, send speech process notice to a PoC user, inform that a PoC user obtains the floor on the one hand, the system information such as holding time of will making a speech on the other hand is shown to a PoC user, makes a PoC user can utilize the time of acquisition to carry out group's speech better.

Step 403, PoC centralized control server send message to user terminal B by the local access server B of PoC, inform that user terminal B receives the Talk Burst that user terminal A is sent, described message is carried system informations such as user profile such as speech theme and speech holding time.

In this step, the local access server B of PoC is after receiving the message that PoC centralized control server sends, and after can handling the additional information of carrying in the message, the additional information after will handling again sends to user terminal B by the control messages of making a speech.

After user terminal B receives above-mentioned speech control messages, send talker ID notice, and additional information is shown to the 2nd PoC user, make the 2nd PoC user can know the information such as body matter of this speech in advance to the 2nd PoC user.

Step 404, user terminal A are set up talking path, send medium step by step by the local access server A of PoC, PoC centralized control server and the local access server B of PoC and flow to user terminal B, and flow process finishes.

Embodiment two,

Fig. 5 shows is that user terminal A is sent speaking request but the processing procedure that do not obtain the floor, specifically may further comprise the steps:
