Description

The present invention claims the priority of a Chinese patent application filed on July 31, 2008 by the Chinese Patent Office, the application number is 200810144078.5, and the invention is entitled "a communication time control method and apparatus". The entire contents are incorporated herein by reference. Technical field

The present invention relates to the field of communication technologies, and in particular, to communication time control techniques. Background technique

With the development of IP and IMS technologies, there are more and more various telecommunication services, including a relatively fast-developing telecommunication service - PoC, Push to talk over Cellular service. .

PoC is a two-way, instant, multi-party communication method that uses half-duplex work, allowing users to communicate with one or more users. The types of media that can be sent by communication include voice, audio, video, and discrete media (including text, pictures, etc.). ).

The PoC service uses a client/server model. The entire PoC system is mainly composed of a PoC server and a PoC client. The PoC server is an application layer function entity of the PoC service, and provides a PoC service application function in the network. The PoC server can provide a PoC control function (CF, Controlling PoC Function) or provide a PoC participation function (PF, Participating PoC Function) or provide both Kind.

Only one user can speak at the same time in a PoC session. The user who wants to speak first requests to obtain the floor. After being allowed, the user can communicate with the user or send the media to be sent to the participant of the group session through the PoC server. . The PoC defines a Media Stream Control Protocol (MBCP) for controlling the media stream in the PoC service. When the PoC client requests the floor to the PoC server, the PoC client can send an MBCP request message to the PoC control function server. The PoC control server sends an MBCP permission message to the requesting client and reports the MBCP occupation message to other clients participating in the PoC session, if the request is reviewed and the conditions permit. At this point, the user who is allowed to speak can send media to other session participants.

In order to enable different levels of users to use differentiated PoC services, PoC services are also defined. The four priorities are:

I. Preemptive priority, which can interrupt the speech of other priority users and directly obtain the right to speak;

II. High priority, the right to speak can be given priority in the voting application queue after the release of the floor;

III. Ordinary priority. After the release of the floor, if there is no other priority request, the voice can be obtained in the floor of the floor.

IV. Receive-only level, only receive-level PoC users can only receive media.

The existing PoC control server controls the time when the user sends the media stream, and uses the PoC to control the pre-configured parameters on the server, such as configuring the highest priority parameter allowed for each user, and the fixed speaking time.

The parameter T2 of the stop talk timer is pre-configured on the PoC control server. When the PoC control server allocates the media floor for the requesting user, the duration T2 set by the stop talk timer is used each time. For example, the PoC client requests a floor using the MBCP request message as shown in Figure 1, and the request contains the priority parameter MB-priority that the user wishes to use.

The MBCP allowed message structure sent by the PoC control server to the requesting PoC client is as shown in the figure.

2, which includes the length of time that the PoC control server allocates to the requesting user for the current speech, the length of time is from the pre-configuration on the PoC control server, and the same speaking time is allocated for each request of the user. .

The length of the stop talking time value is equal to the length of the stop talk timer in the PoC control server, T2.

In the current PoC service, the mediator's voice is also controlled by the dispatcher Moderator. In the network where the dispatcher Moderator is deployed, the dispatcher Moderator sends the media flow control protocol MBCP permission message to the requesting PoC client. The Moderator allocates the speaking time also using the same length of time, regardless of the user's request to speak.

In the research and practice of the prior art, the inventors found that the prior art has the following problems:

In the prior art, the media stream floor control process lacks a flexible and effective management method for the control of the user's speaking time. For the user requests of different priorities, the same speaking time is allocated, and the network resources cannot be properly allocated. It is inconvenient for the user to use. Summary of the invention

The embodiment of the invention provides a communication time control method and device, which can make the control of the media stream floor in the PoC session and the allocation of the user's speaking time more flexible and effective, and achieve the purpose of better utilizing the session common resources.

A communication time control method provided by an embodiment of the present invention includes:

The embodiment of the invention provides a method for allocating the speaking time of the client while controlling the speaking right of the media stream.

In the embodiment of the present invention, each time the client requests the right to speak the media stream, the request message includes the speaking time that the client wishes to obtain this speech. In this way, the user can estimate the speaking time that he or she wishes to obtain before requesting the floor, and include the speaking time that the speech is desired to obtain in the speech request message. In addition, the spoofing time rule or policy corresponding to the user's various spoofing requests may be preset on the system side according to the operator policy, for example, the corresponding uttering request time is set based on the priority of the user's uttering request, and when the user equipment's uttering request is received, Assigning a speaking time to the user equipment according to the speaking time rule corresponding to the set of various speaking requests of the user; or setting a specific speaking policy, for example, using the speaking time length set in the policy: the first speaking request use policy The first time to speak, the second time to request the use of policy Slightly the second speaking time, and so on.

The present invention will be described below by taking a Poc communication service system as an example.

The PoC control server receives a speech request message sent by the user equipment, where the speech request message includes the speech time information of the current request;

When requesting to speak, firstly, according to the estimated speaking time, the time parameter for requesting the speech is set in the terminal device, and then the media flow control protocol MBCP request is sent to the PoC control server, which includes the speaking time requested by the user.

After receiving the request sent by the user, the PoC control server sends an MBCP permission message to the PoC client requesting the uttering according to the requesting time of the user, and then combines the operator policy, in the case that the MBCP allowed message structure remains unchanged. , expand the fields such as the timer and stop the talk time.

In the embodiment of the present invention, the extended media stream floor control protocol MBCP request message and the media stream floor control protocol MBCP allow messages. In the extended MBCP request message, the request speech time information is added, and the extended message format is as shown in FIG. 3:

The PoC control server may allocate a speaking time to the PoC user according to the request or the operation policy of the PoC user. If the speaking time requested by the user is less than the maximum long-serving request time allowed by the operator at _T2max , the PoC control server allocates the speaking time according to the user's request, and returns an MBCP permission message. If the speaking time requested by the user is greater than the carriers allow users maximum speaking time T2 _max, when the PoC server policy allows user request beyond the allotted time, otherwise the PoC control server according to user carriers allow the maximum speaking time allocation request, That is, the PoC control server returns an MBCP Allow message, and the MBCP allows the current talk timer in the message to use the value of T2 _max . If the user has set a request to reject the request when the longest talk time request is not met, the PoC control server may also reject the user's request for the request, and the reason for the failure is that the user request time is greater than the maximum allowed time.

It should be specially noted that in some cases, for example, the media type of the session is only voice. Or, if an implicit media speaking request has been negotiated, the PoC client can also use the INVITE request message to request to establish a session and request a floor during the session establishment process. At this time, the user may also include the speaking time obtained by the user request in the INVITE request, and the PoC control server allocates the speaking right to the user according to the speaking time requested by the user while completing the session establishment. The use of the MBCP request message is essentially the same as the use of the INVITE request message to implicitly request the floor. The following describes the control procedure in detail using the MBCP request message as an example.

Embodiment 1

Referring to FIG. 4, a communication time control method is provided in this embodiment. The specific process is as follows: Step 101: When the session is idle (no user is speaking), the client UE1 to be uttered sends an MBCP request to the home PoC server. The format of the message, as shown in Figure 3, includes the identifier of the client, the priority of the current use, and the time of the user to speak for the request.

Step 102: The home PoC server of the UE1 forwards the MBCP request message to the PoC control server that controls the allocation of the voice, and the content of the message is the same as the message content in step 101.

Step 103: The PoC control server allocates a floor for the client UE1 that requests to speak, and returns an MBCP permission message to the client UE1, allowing the user to speak. The message includes the PoC control server assigning the longest speech to the client for the current request. time. In this step, the PoC control server allocates the speaking time according to the speaking priority, the speaking request time, and the longest speaking time corresponding to the priority allowed by the server, if the speaking time requested by the user is within the allowable range of the server. The server allocates time according to the user request. If the speaking time requested by the user exceeds the allowed range of the server, the server allocates the speaking time to the user according to the policy on the server;

Step 104: The home CAC of the PoC client UE1 forwards the received MBCP permission message to the UE1, and the message content is the same as the message content in step 103.

Step 105: After the PoC control server sends the MBCP permission to the UE1 that requests to speak,

Other PoC clients in the PoC session UE2 sends an MBCP occupation message, indicating that the floor of the session has been allocated to the UE1, and the UE2 needs to wait to receive the media content sent by the UE1, where the message includes the identification information of the UE1;

Step 106: The home PoC server of UE2 forwards the received MBCP occupation message to UE2, the message content is the same as the message content in step 105;

Step 107: After obtaining the floor, the UE1 may send the media, where the media is first sent to the PoC server to which the UE1 belongs.

Step 108: The home PoC server of the UE1 forwards the media to the PoC control server. Step 109: The PoC control server forwards the media to the home PoC server of the UE2. Step 110: The home PoC server of the UE2 forwards the media to the UE2.

In this way, the floor can be assigned based on the priority of the user, and the time of the speech can be allocated according to the user's request.

Embodiment 2

The method provided by this embodiment is basically the same as that in the first embodiment. The difference is that the dispatcher Moderator is deployed in the PoC service system, and the voice and time of the user are allocated by the dispatcher Moderator. Referring to FIG. 5, the MBCP request message sent by the user equipment of the client is forwarded to the dispatcher Moderator, and the MBCP request message includes the speaking time that the current speech wants to obtain, and the Moderator can respond according to the priority of the user request and the requested speech. Time to assign the user's floor and speaking time.

The dispatcher Moderator can allocate the speaking time to the PoC user according to the request of the PoC user or the Moderator policy. If the user requests speaking time is less than the maximum allowed user speaking Moderator request time T2 _max, Moderator can assign the speaking time requested by the user, and allows the return MBCP message. If the user requests the speaking time to be longer than the maximum user speaking time T2 _max allowed by the Moderator, if the Moderator policy allows the exceeding, the time is allocated according to the user request. Otherwise, the Moderator allocates according to the maximum length of the allowed user request, that is, the Moderator returns MBCP. Allow message, MBCP allows the current talk timer in the message to use the value of T2 _max . If the user has set the request to reject the request when the longest talk time request is not met, the Moderator can also reject the user's request for the request. The reason for the failure is that the user request time is greater than the maximum allowed time.

Steps 201 and 202 are the same as steps 101 and 102 in the first embodiment;

Step 203: The Moderator is configured to manage the media stream control in the network. Therefore, the PoC control server forwards the MBCP request message of the UE1 to the PoC participating server to which the Moderator belongs. The content of the message is the same as the content of the message in step 101. Step 204: The home PoC server of the Moderator forwards the MBCP request message to the Moderator for processing, and the content of the message is the same as the message content in step 201.

Step 205: The Moderator allocates a floor for the client UE1 requesting the floor according to the priority of the request and the requesting time of the UE1, and returns an MBCP permission message to the client UE1 to allow the user to speak. The message includes the Moderator for the client UE1 to allocate the longest talk time for the current request, and first sends it to the PoC participating server to which the Moderator belongs. In this step, the Moderator allocates the speaking time according to the speaking priority, the speaking request time, and the longest speaking time corresponding to the priority allowed by the Moderator, and if the length of the speaking time requested by the user is within the allowable range, The Moderator allocates time according to the user request. If the speaking time requested by the user exceeds the allowed range, the Moderator allocates the speaking time to the user according to the policy. For example, the user equipment may be allocated the longest speaking time allowed by the system according to the user's request. Or assigning a speaking time to the user equipment according to the speaking time information requested by the user equipment according to a predetermined policy.

Step 206: The PoC participating server that the Moderator belongs to forwards the MBCP permission message to the PoC control server, and the content of the message is the same as the message content in step 205.

Step 207: The PoC control server forwards the MBCP permission message to the PoC participating server to which the UE1 belongs, and the content of the message is the same as the message content in step 205.

Step 208: The home PoC server of the PoC client UE1 forwards the received MBCP permission message to the UE1.

Step 209: After the PoC control server sends the MBCP permission to the UE1 that requests to speak,

Other PoC clients in the PoC session UE2 sends an MBCP occupation message, indicating that the floor of the session has been allocated to UE1, and UE2 needs to wait to receive the media content sent by UE1, and the message includes the identification information of UE1;

Step 210: The home PoC server of UE2 forwards the received MBCP occupation message to UE2, and the message content is the same as the message content in step 209.

In addition, in the case that the PoC control server or the Moderator policy allows, the PoC user can also request the maximum time to exceed the T2 _max . For example, the authorized PoC user can use the emergency speech when the preemption priority is used, and the speech exceeding T2 _max is obtained. Time, the time of speaking can be determined according to the request of the PoC user. By completing the above steps, the client UE1 obtains the media stream floor and can send the media stream to other participants in the session. In this way, the floor can be assigned based on the priority of the user, and the time of the speech can be allocated according to the user's request.

Embodiment 3

In this embodiment, a SIP request message is used, for example, a PUBLISH request message is used, and an Extensible Markup Language (XML) multi-purpose Internet Mail Extensions message body is included in the request message. The content of the speaking time (such as the speaking request time corresponding to each priority speaking request) is sent to the PoC control server by using the content contained therein. After the user requests the media floor again after each setting, the request message only needs to include the speaking priority request, and does not include the speaking time. At this time, the PoC control server allocates the speech according to the already set speaking request time rule or policy. time. With this method, you can flexibly set the management request time. The speaking time setting request is sent before the floor is requested, and then each of the speaking requests implicitly uses the set speaking request time until the new speaking request time is requested again.

The flow of the communication time control method provided by the implementation of the present invention is as shown in FIG. 6, and the specific process includes the following steps:

Step 301: After establishing or joining a PoC session, the client UE1 first sends a set speaking time rule to the PoC control server, such as a request for the speaking time information corresponding to the speaking request in various priority situations. The UE1 may send the configured SIP request message to the home PoC server, where the message destination is a PoC control server address, and the message includes a speech time request corresponding to each of the speech requests that the user may use;

Step 302: The PoC server to which the UE1 belongs forwards the setting request of the UE1 to the PoC control server, and the content of the message is the same as the content of the message in step 301.

Step 303: After the PoC control server records the time setting data of UE1, it returns 200 to UE1.

OK response, the message is sent to the home PoC server of UE1. If the speaking time requested by the user is configured within the allowable range of the server, the server completes the setting according to the user request, and sets the speaking request time for the user, which may be beyond the longest speaking time according to the user's request or set to the user according to the longest speaking time. The 200 OK message contains the settings set by the PoC control server for the UE1 user. Request time

Step 304: The home PoC server of the UE1 forwards the received 200 OK response to the UE1, and the content of the 200 OK message is the same as the content of the message in step 303.

Step 305: The UE1 sends an MBCP request message to the home PoC control server, where the message includes the identifier of the client, the priority of the current use, and the like.

Step 306: The home PoC server of UE1 forwards the MBCP request message to the PoC control server that controls the distribution of the voice, and the content of the message is the same as the message content in step 305.

Step 307: The PoC control server allocates a floor for the client UE1 that requests to speak, and returns an MBCP permission message to the client UE1, allowing the user to speak. The message includes the PoC control server assigning the longest speech to the client for the current request. The length of time and time are determined by the pre-set talk time configuration of UE1 recorded on the PoC control server;

Step 308: The home PoC server of the UE1 forwards the received MBCP permission message to the UE1, and the message content is the same as the message content in step 307.

Step 309, after the PoC control server sends the MBCP permission to the UE1 that requests to speak,

Step 310: The home PoC server of the UE2 forwards the received MBCP occupation message to the UE2, and the message content is the same as the message content in step 309.

Step 311: After obtaining the floor, the UE1 may send the media, where the media is first sent to the PoC server to which the UE1 belongs.

Step 312: The home PoC server of the UE1 forwards the media to the PoC control server. Step 313: The PoC control server forwards the media to the home PoC server of the UE2. Step 314: The home PoC server of the UE2 forwards the media to the UE2.

In the method provided by the embodiment of the present invention, the user can set the speaking time request after each session is established, and can perform setting multiple times in one session. After each setting, the user implicitly uses the pre-set request speech time in multiple speech requests, and the PoC server can complete multiple floor allocation and speech time allocation according to the user's setting. Embodiment 4

As another method for the user to request the speaking time setting, the user can also use the SIP PUBLISH request to set the speaking request time for each priority speaking request on the home PoC server before establishing or joining the session. After the user establishes or joins the session, the PoC home server can automatically add the speaking time request information to the MBCP request message sent by the user.

The flow of the communication time control method provided by the implementation of the present invention is as shown in FIG. 7, and the specific process includes the following steps:

Step 401: The client UE1 first sends a request for setting the speaking time information corresponding to the speaking request in various priority situations to the home PoC server, and the request may be used before the session is established or after the session is established. Multiple PoC sessions until the PoC user requests to set up the update again. The UE1 may send the configured SIP request message to the home PoC server, where the message includes a speech time request corresponding to various speech requests that the user may use;

Step 402: After the PoC home server records the time setting data of UE1, it returns 200 to UE1.

OK response. If the speaking time requested by the user is configured within the allowable range of the server, the server completes the setting according to the user request, and sets the speaking request time for the user, which may be set to the user according to the user's request to exceed the maximum speaking time or according to the longest speaking time. The 200 OK message includes the speech request time set by the PoC home server for the UE 1 user;

Step 403: If no user speaks, UE1 sends the message to the home PoC server.

The MBCP request message includes the identifier of the client, the priority used by the current session, and the like. Step 404: The home PoC server of the UE1 forwards the MBCP request message to the PoC control server that controls the voice distribution, and adds the user to the message. The request request time information, according to the time set by the user in advance in the home server and the priority used by the floor request;

Step 405: The PoC control server allocates a floor for the client UE1 that requests to speak, and returns an MBCP permission message to the client UE1, allowing the user to speak. The message includes the PoC control server assigning the longest speech to the client for the current request. Time, the length of time is determined according to the speaking time of the request contained in the MBCP request message;

Step 406: The home PoC server of UE1 forwards the received MBCP permission message to

UE1, the message content is the same as the message content in step 405; Step 407: After sending the MBCP permission to the UE1 that requests to speak, the PoC control server sends an MBCP occupation message to the other PoC client UE2 in the PoC session, indicating that the floor right of the session has been allocated to the UE1, and the UE2 needs to wait to receive the media sent by the UE1. Content, the message contains the identification information of UE1;

Step 408: The home PoC server of UE2 forwards the received MBCP occupation message to

UE2, the message content is the same as the message content in step 407;

Step 409: After obtaining the floor, the UE1 may send the media, where the media is first sent to the PoC server to which the UE1 belongs.

Step 410: The home PoC server of the UE1 forwards the media to the PoC control server. Step 411: The PoC control server forwards the media to the home PoC server of the UE2. Step 412: The home PoC server of the UE2 forwards the media to the UE2.

In the solution provided by the embodiment of the present invention, the user can set the speaking time request before the session is established, and can be set multiple times at any time. After each setting, the user implicitly uses the pre-set speech request time in multiple speech requests, and the PoC home server inserts the speech request time into the speech request, and the PoC control server can also complete the speech distribution and the speech time allocation.

Embodiment 5

In this embodiment, a method for performing data management and maintenance is accessed by using an Extensible Markup Language XML Configuration Access Protocol (XCAP). The PoC user sets the time for the user to speak on the XML Document Management Server (XDMS, XML Document Management Server). When the PoC user establishes or joins the PoC session, or the PoC user updates the settings on the XDMS, the PoC control server obtains the XDM data and policies set by the PoC user from the XDMS, and processes the session process of the PoC user in the PoC session. . Therefore, as long as the user completes the setting on the XDMS in advance, each time the user requests the media floor again, the request message may not include the speaking time. At this time, the PoC control server according to the statement that the user has set on the XDMS server. The request time is allocated to the speaking time. Using such a method, the user can flexibly set and manage his own speaking time, and send a speaking time setting request before requesting the speaking right, and each subsequent speaking request implicitly requests the set speaking requesting time until the user Request again to set a new speaking request time. The media flow control process in this embodiment is as shown in FIG. 8. The specific process is as follows: Step 501: The client UE1 sends a request for setting the speaking time corresponding to the speaking request in the case of various priorities to the home XDMS server. The UE1 may send a configured XCAP (XML Configuration Access Protocol) PUT request message to the XDMS server, where the message includes a request time for the various speech requests that the user may use.

Step 502: After completing the time setting data of the UE1, the XDMS server returns a 200 OK response to the UE1. If the speaking time requested by the user is configured within the allowable range of the XDMS server, the XDMS server completes the setting according to the user request. If the speaking time configuration requested by the user exceeds the allowable range of the XDMS server, the XDMS server follows the policy and the maximum allowed value on the XDMS server. Complete the user speaking time setting. The 200 OK message includes the speaking request time set by the XDMS server for the UE1 user;

Step 503: After the UE1 establishes a PoC session with other PoC users, the PoC control server first obtains the XDM data and policy of the UE1 from the XDMS, and saves the data in the PoC control server.

Step 504: In the case that no other user is speaking, the UE1 sends an MBCP request message to the home PoC server, where the message includes the identifier of the UE1, the priority of the current session, and the like. Step 505: The home PoC server of the UE1 will MBCP. The request message is forwarded to the PoC control server that controls the allocation of the floor, and the content of the message is the same as the message content in step 504;

Step 506: The PoC control server allocates a floor for the client UE1 that requests to speak, and returns an MBCP permission message to the client UE1, allowing the user to speak. The message includes the PoC control server assigning the longest speech to the client for the current request. The length of time and the length of time are determined by the pre-set speech request time configuration of the UE1 in the XDM data saved on the PoC control server;

Step 507: The home PoC server of the UE1 forwards the received MBCP permission message to the UE1, and the message content is the same as the message content in step 506.

Step 508: After the PoC control server sends the MBCP permission to the UE1 that requests to speak,
