Description

Method and system for determining media sending right of multi-party communication service

technical field

The invention relates to media resource allocation technology for multi-party communication services, in particular to a method and system for determining media transmission rights for multi-party communication services.

Background technique

At present, in the communication system, various services participated by individual users or collective users have been realized, and the specific communication methods include: text, voice, video, and multimedia combination, etc. General communication services are mainly oriented to individual users, and usually only one or two user equipments (UEs) perform communication. In the communication service in which collective users participate, there are usually one or more groups of users communicating at the same time, that is to say, the communication process is not a two-party communication consisting of a calling party user and a called party user as is usually seen. There may be multiple calling party users and multiple called party users communicating. Therefore, the services in which such collective users participate are also called multi-party communication services.

Currently, mainstream multi-party communication services include: push-to-talk (PoC) services and conference (Conference) services in cellular systems. In the multi-party communication service network, the centralized processing server is used to centrally control the session signaling process, and is responsible for granting each communication party the right to send media, and perform copying and distribution in media transmission, etc. The centralized processing server refers to: in the PoC service network The Controlling PoC Server (Controlling PoC Server), the Conference Server (Conference Server) in the Conference business network, etc. This article will take the PoC service as an example to illustrate the problems in the prior art and the solution of the present invention.

The PoC service communication system is a half-duplex communication system. The system needs to control the distribution of the media transmission rights of multiple users of the group conversation. Control). The current PoC service implements a mechanism for each user to seize the right to speak. Users apply for the right to speak to the system before speaking, and the system grants the right to speak to the user who first applies for the right to speak among the users currently participating in the session, and rejects subsequent speeches sent by other users. right to apply. Therefore, the PoC service system only transmits the voice stream of the user who has the right to speak, so that the users participating in the conversation cannot hear the voices of other users.

Wherein, each session user may apply for the speaking right for himself by sending a request for the speaking right, and the controlling PoC server of the current session assigns the speaking right to the user who sends the request. The session user can also apply for the speaking right for other users by sending a speaking right request, and the controlling PoC server of the current session allocates the speaking right to the corresponding user according to the information carried in the speaking right request. In addition, the PoC server can also actively allocate the right to speak to each user according to a certain processing logic according to the allocation policy.

When the PoC server grants the user the right to speak, it will send a floor granted notification to the UE, and then the UE will directly transmit its own media data to the PoC server, and then the PoC server will distribute the received media data to each user in the current session. UE. For example: in the voice service of PoC, once the UE receives the Floor granted notification, the microphone of the PoC terminal is turned on, so that the PoC terminal starts to transmit various voice data received by the microphone to the PoC server.

However, there are still some problems in the current floor control. Especially for those users who are actively granted the right to speak by the PoC server, or users who request the right to speak for them by other users, these users will not necessarily accept the currently granted right to speak after being granted the right to speak, nor will they necessarily have Prepare to transfer media data. But at this time, the media data from the user has been distributed to each session user by the PoC server. These media data are likely to be some meaningless data, which will waste system transmission resources. For example: when a certain UE user is not ready to speak, the UE suddenly receives a Floor granted notification, causing its microphone to automatically turn on. At this time, the voice received by the microphone is likely to be some external noise, or from the user's communication with the user. Conversation speaks irrelevant speech.

The current control mechanism for media transmission rights will not only waste transmission resources, but may also cause inconvenience to users. Say, the UE's camera will be activated, and the disheveled image of the user will be passed on to the various users of the session, thus creating an awkward situation.

Contents of the invention

Detailed ways

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

The invention discloses a method for determining the media transmission right of a multi-party communication service. The main design idea is: after receiving the notification of granting the media transmission right, the UE judges whether to accept the media transmission right, and if it accepts, it starts to transmit the user's media The data is sent to the centralized processing server of the current business session; after the centralized processing server of the current business session grants the user the media transmission right, it judges whether the UE accepts the media transmission right, and if the UE accepts it, it starts to receive media data from the UE and distributes it to the current Each other UE of the traffic session.

Here, there are basically two methods for the centralized processing server to determine whether the UE accepts the media transmission right: 1. Judging according to the notification from the UE indicating whether to accept the media transmission right; the notification for indicating whether to accept the media transmission right includes: A notification indicating acceptance of the media transmission right and a notification indicating rejection of the media transmission right; 2. Controlling the PoC server to make a judgment according to whether the media data from the UE is received within a preset timing period.

Among them, the right to send media generally refers to the right to speak (Floor). In the future development stage of the multi-party communication service, other types of right to send media may also appear, which also belong to the scope of the right to send media in the present invention. The present invention can be applied in the floor control flow of multi-party communication services such as PoC service and conference service. In the PoC service, the centralized processing server is the controlling PoC server of the current PoC session, and in the Conference service, the centralized processing server is the Conference server of the current Conference session. The centralized processing server of the present invention can be any server for centralized processing of multi-party communication business sessions. With the development of multi-party communication services, other servers for centralized processing of business sessions other than control PoC servers and Conference servers may appear , they also all belong to the centralized processing server category of the present invention.

The method of the present invention will be described in detail below by taking the speaking right control flow of a typical PoC service as an example. In a PoC session, the UE exchanges session control signaling and media data with the controlling PoC server through its own participating PoC server, where the participating PoC server mainly plays a role of forwarding. However, the method of the present invention relates to the improvement of the processing of the control PoC server. In order to simplify the description, in the embodiments described herein, the relevant processing of the participating PoC server is omitted, and the participating PoC server is not shown in the accompanying drawings, and the processing entities only include: UE and control PoC server.

Fig. 1 is a schematic diagram of the processing flow of a preferred embodiment of the method of the present invention. In this embodiment, the PoC control server judges whether the UE accepts the right to speak according to the notification from the UE indicating whether to accept the right to speak. As shown in Figure 1, after the PoC session is established between the UE and the controlling PoC server, the specific processing includes:

Step 101: Control the PoC server to assign the right to speak to the UE, send a floor granted notification to the UE, send a floor taken notification to each other UE in the current PoC session, and start receiving user requests from the UE. For the notification indicating whether to accept the right to speak, the notification indicating whether to accept the right to speak may be a notification indicating acceptance of the right to speak or a notification indicating rejection of the right to speak.

Step 102: The UE judges whether to accept the currently granted right to speak, and if so, executes step 103; otherwise, executes step 103'.

Here, when the UE receives the right-to-speak grant notification from the controlling PoC server, it will prompt the user whether to accept the right to speak, then receive an operation command from the user, and judge whether the user accepts the right to speak according to the operation command. For example, the UE may display to the user that the right to speak is currently granted in the form of a man-machine interface, and the user may input an operation command through the man-machine interface to indicate whether to accept the right to speak.

At this time, the UE does not transmit media data, and only transmits media data when the user is sure to accept the right to speak, so as to avoid sending invalid media data when the user is not prepared.

Step 103: The UE sends a notification indicating acceptance of the right to speak to the controlling PoC server, and transmits media data such as audio/video received by itself to the controlling PoC server.

Step 104: After the control PoC server receives the notification indicating acceptance of the right to speak as described in step 103, it determines that the UE accepts the right to speak currently granted, starts to receive media data from the UE and distributes it to each other UE in the current PoC session, and ends the current processing flow .

Step 103': The UE sends a notification indicating that the right to speak is rejected to the controlling PoC server.

Step 104': After receiving the notification indicating that the right to speak is rejected as described in step 103', the control PoC server determines that the UE refuses to accept the right to speak currently granted, releases the right to speak assigned to the UE in step 101, and then reports to the current PoC session Each UE sends a floor free notification to end the current processing flow.

Considering that the UE may not be able to successfully send the notification indicating whether to accept the right to speak to the control PoC server, which will make the entire processing flow of the present invention unable to go on, so the timer can be further set in the control PoC server, in step In 101, the PoC server is controlled to further start the timer, and the timer will be restarted when receiving a notification from the UE indicating acceptance of the right to speak. The control PoC server will judge whether a notification from the UE indicating acceptance of the right to speak is received within the timing period of the preset timer, if yes, then judge that the UE accepts the right to speak, and perform step 104; otherwise, the timer expires, Then it is judged that the UE refuses to accept the right to speak, and step 104' is executed.

Fig. 2 is a schematic diagram of the processing flow of another preferred embodiment of the method of the present invention. In this embodiment, the control PoC server judges whether the UE accepts the right to speak according to whether it receives media data from the UE within a preset timing period, so a timer should be set in the control PoC server. As shown in Figure 2, after the PoC session is established between the UE and the controlling PoC server, the specific processing includes:

Step 201: Control the PoC server to assign the right to speak to the UE, send a right-to-speak notification to the UE, send a right-to-speak occupancy notification to each other UE in the current PoC session, start the set timer, and start receiving media data from the UE . Here, the timer will be restarted when media data is received from the UE.

Step 202: The UE judges whether to accept the currently granted right to speak, and if so, executes step 203; otherwise, executes step 203'. The judgment in this step is the same as the judgment method described in step 102, and will not be described in detail here.

Step 203: the UE starts to transmit the received media data such as audio/video to the controlling PoC server. After the control PoC server receives the media data from the UE within the preset timer period, it judges that the UE accepts the currently granted right to speak, starts to distribute the media data from the UE to other UEs in the current PoC session, and ends the current PoC session. processing flow.

Step 203': Control the PoC server to never receive media data from the UE within the preset timer period, that is, the timer expires, then judge that the UE refuses to accept the right to speak, and release the right to speak assigned to the UE in step 201 , and then send a floor idle notification to each UE in the current PoC session, and end the current processing flow.

Based on the method of the present invention, the present invention also proposes a system for determining the media transmission right of a multi-party communication service. The system includes: a UE, a centralized processing server for service sessions, and a media transmission right accepting unit.

Wherein, the UE is used to receive the media sending right grant notification from the centralized processing server, and send the media sending right grant indication to the media sending right accepting unit when receiving the media sending right granting notification; when receiving the media sending right accepting unit When receiving the media transmission right acceptance instruction, it is judged that the user accepts the currently granted media transmission right, and starts to transmit media data to the centralized processing server. The centralized processing server is used for judging whether the UE accepts the currently granted media sending right, and receiving media data from the UE and distributing the media data when judging acceptance. The media sending right accepting unit is used to receive the media sending right grant indication from the UE, receive the operation command from the user, and send the media sending right acceptance indication to the UE when it is judged to accept the media sending right. At this time, the centralized processing server may determine whether the UE accepts the media transmission right according to whether the media data from the UE is received.

In addition, the media sending right accepting unit may also output a notification indicating whether to accept the media sending right to notify the centralized processing server whether the UE accepts the media sending right. In this way, the system of the present invention further includes a media sending right determining unit. The media sending right determining unit is configured to receive a notification indicating whether the UE accepts the media sending right from the media sending right accepting unit, and send a media sending right determining instruction to the centralized processing server when receiving the notification indicating acceptance of the media sending right. The centralized processing server judges that the UE accepts the currently granted media transmission right when receiving the media transmission right determination indication, and starts to receive media data from the UE and distribute the media data.

It can be known from the foregoing that the centralized processing server may be a control PoC server or a conference server, and the right to send media generally refers to the right to speak. The implementation of the system of the present invention will be described in detail below by taking control of the PoC server and the right to speak as an example.

Fig. 3 is a schematic diagram of the composition and structure of a preferred embodiment of the system of the present invention. As shown in FIG. 3 , this embodiment includes: a UE, a control PoC server, and a media sending right accepting unit. The process of determining the right to speak will be described below in conjunction with FIG. 3 , so as to further illustrate the working principle of the system of the present invention.

First, the controlling PoC server determines that the UE is to be granted the right to speak, and then sends a notification of granting the right to speak to the UE. The UE then sends the indication of granting the speaking right to the media sending right accepting unit.

Then, the media transmission right accepting unit will display prompt information to the user and receive the user's operation command, judge whether the user accepts the currently granted right to speak according to the operation command, and output a right to speak acceptance indication to the UE when judging that the user accepts the right to speak. After receiving the right-to-speak acceptance instruction, the UE starts to transmit the user's media data to the controlling PoC server. For example, after receiving the right-to-speak acceptance instruction, the UE will turn on the microphone, start receiving the user's voice and transmit it; When instructed, the microphone will remain off to avoid invalid voice data transmission.

Finally, when the control PoC server receives the media data from the UE, it will judge that the UE has accepted the right to speak, so as to distribute the media data from the UE among the UEs in the current PoC session.

On the basis of the above-mentioned system of the present invention, it may further include a media sending right determining unit. At this time, as shown in FIG. 3 , after judging whether the user accepts the speaking right, the media sending right accepting unit further sends a notification indicating whether to accept the speaking right to the media sending right determining unit. The notification indicating whether to accept the right to speak may be a notification indicating rejection of the right to speak or a notification indicating acceptance of the right to speak. When the media sending right determining unit receives the notification indicating acceptance of the speaking right, it judges that the UE accepts the currently granted speaking right, and sends the speaking right determination instruction to the controlling PoC server. The control PoC server judges that the UE accepts the right to speak after receiving the right-to-speak determination instruction, thereby starting to receive media data from the UE and distribute it to each UE of the current PoC session; When the notification is made, it is judged that the UE rejects the currently granted right to speak, and sends an indication that the right to speak is denied to the controlling PoC server. After receiving the indication that the right to speak is denied, the controlling PoC server judges that the UE refuses the right to speak, thereby releasing the right to speak allocated to the UE. Here, the media transmission right determining unit will not send the right to speak confirmation instruction when receiving the notification indicating that the right to speak is rejected, so that the control PoC server will judge that the UE does not accept the right to speak and not perform media data transmission.

In addition, the system of the present invention may further include a timer. As shown in Figure 3, the timer is connected to the control PoC server, and the control PoC server can judge whether it exceeds the preset timing period according to whether it receives the timeout indication from the timer, so as to determine whether to receive Whether to receive the media data from the UE, or whether to receive the right-to-speak determination instruction from the media transmission right determination unit. When the system of the present invention does not include a media transmission right determination unit, if the control PoC server receives media data from the UE and does not receive a timeout indication, it judges that the UE accepts the currently granted right to speak; otherwise, it judges that the UE refuses to accept the right to speak . When the system of the present invention includes a media transmission right determination unit, if the control PoC server receives the right-to-speak determination indication from the media transmission right determination unit and does not receive a timeout indication, it judges that the UE accepts the currently granted right to speak; otherwise it judges that the UE Declined to accept the floor.

In the above embodiments, the media sending right accepting unit may be an independently set entity or integrated in the UE connected to it; the media sending right determining unit may also be an independently set entity or integrated in the centralized processing server connected to it; The timer can also be an independently set entity or integrated in a centralized processing server connected to it.

To sum up, the application of the method and system of the present invention can well solve the problems existing in the current multi-party communication service media transmission right control technology. The data will be received by the UE and distributed to other UEs through the centralized processing server, thereby basically avoiding the transmission of invalid media data, improving the utilization rate of system transmission resources, and bringing better service experience to users.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
