Background technology
In development of internet technology, multi-party communication becomes a kind of business of widespread usage gradually, such as PTT (PoC, Push to Talk over Cellular) system, meeting (Conference) system and group system etc.In multi-party communication system, need unique control point to come multi-party communication is carried out unified management, to guarantee consistency and real-time to the control of each communication user in the multi-party communication.Here said management specifically is meant medium sending right (Floor) processing, be that request is initiated as speaking request in the control point that communication user in certain group need be in system, after the control point was adjudicated above-mentioned request and permitted, this communication user could send media stream datas by other communication users in this group.
At present, in multi-party communication system such as POC system or group system, realized voice-based single medium data medium transmission route processing.Fig. 1 is the flow chart that the prior art medium sending right is handled, and in PoC system or group system, only exists the medium sending right of sound-type is handled; Suppose that the user in certain group asks speech, existing concrete the processing may further comprise the steps:
Step 100: the speech user sends medium sending right request (Floor Request) message by user terminal 1 (UE1) to the control point server.
Because the medium sending right type in the multi-party communication only has single sound-type, therefore, after server receives Floor Request message, promptly begins decision process.
Step 101: whether server is agreed to authorize UE1 medium sending right according to preset strategy judgement, if agree, and execution in step 102b then; Otherwise, execution in step 102a.
Described strategy can be whether medium sending right is current occupied, this UE1 medium sending right etc. of whether having the right to apply for.Such as: if the current media transmission route by other CUs, is then disagreed with; Otherwise agree.
Step 102a: server sends the medium sending right application that refusal medium sending right (Floor Reject) message is refused UE1, process ends afterwards to UE1.
Step 102b~step 103b: server sends the medium sending right application that permission medium sending right (Floor Grant) message is permitted UE1 to UE1, and other UE transmission medium sending rights notice (Floor Taken) message in the group of UE1 place have been authorized UE1 to notify the current medium sending right of described other UE.
Step 104b:UE1 sends Media Stream (Media Burst) data to other UE of place group.
Development along with broadband network, communication system no longer only is confined to traditional Speech Communication, multimedia service in conjunction with multiple medium types such as audio frequency, video, picture and texts is carried out gradually, by with present combining of data services such as (presence) business, short message, webpage (WEB) are browsed, locating information, propelling movement (PUSH) business, file-sharing, satisfy user's multiple demand.Under the promotion of multiple application, third generation partner program (3GPP) normal structure has been released IP-based IP multimedia subsystem, IMS (IMS) framework, purpose is to use a kind of structure of standardized opening to realize diversified multimedia application in communication network, offers the user and more selects to satisfy user's multiple demand.
POC2.0 is the POC business of the more highest version formulated of present OMA, it is professional expansion and the upgrading of definition among the POC1.0, he allows the user to set up the Multimedia session of communicating by letter immediately with other one or more users by specific keys, allow the user in session, to transmit multiple medium type, as still picture, live video stream, file transfer and text text.The backward compatible POC1.0 of POC2.0 also supports the half-duplex voice business among the POC1.0.
Multimedia service provides various types of media transmission route request for multi-party communication, but, from existing media sending authority processing method, server is only controlled one type medium sending right, can not realize the control to multiple medium sending right.In the existing group system and PoC system that relates to multiple medium, continue to use voice-based single medium and consult control strategy, the complete independent process of the negotiation of each medium type.Because POC2.0 allows to transmit multiple medium type simultaneously in same session, in session, need multiple media stream control signaling is controlled, and these different media flows control signalings are separate and it doesn't matter.Fig. 2 is the processing method schematic diagram of multiple media stream control signaling in the existing POC system.This processing method tangible drawback occurred in the multimedia communications system that multiple medium occur, this drawback is embodied in and mainly shows as following two kinds of situations on the user terminal:
If 1, the audio frequency and video session is arranged when voice conversation carries out, a terminal may obtain two voice transmission routes simultaneously, this moment is because transmission route is separate between the different medium, the control of two voice is separate, and terminal sends a plurality of voice simultaneously can cause confusion in the POC session and very poor user experience.
2, obtain the transmission route of common POC voice conversation at a certain POC user A, when carrying out voice conversation, if another POC user B obtains the transmission route of audio frequency and video session, perhaps obtain the transmission route of audio frequency and video session at a certain POC user D, when carrying out video session, if another POC user E obtains the transmission route of common POC voice conversation, if this moment, A/B or two terminals of D/E all obtained the relevant transmission route of voice, when two terminals send voice simultaneously, other users in the session can hear simultaneously from two user's voice, the user experience of POC session is bad, and for these two terminals (AB or DE), can also hear the another one user's voice in its speech, this has just brought the experience of similar full duplex, and is inconsistent with the characteristic of POC.
Both of these case all causes occurring two voice simultaneously in the POC session, can cause the user experience of POC session bad, does not also meet the semiduplex characteristic of POC session simultaneously.
