Description
Technical field
The present invention relates to the media resource distribution technique of multiway telecommunication service, particularly a kind of medium sending right of multiway telecommunication service is determined method and system.
Background technology
At present, realized the business that various personal users or the user of collective participate in communication system, concrete communication mode comprises: text, voice, video and multimedia combination etc.General communication service only has one or two subscriber equipment (UE) to communicate mainly towards the personal user usually.In the communication service that the user of collective participates in, usually there is the user of one or more groups to communicate simultaneously, that is to say that communication process is not usually a being seen calling part user and the intercommunication that callee user constitutes, what participate in communication has a plurality of calling part user and an a plurality of callee user, therefore, the business of the user of this type of collective participation is also referred to as multiway telecommunication service.
At present, the multiway telecommunication service of main flow comprises: PTT in the cellular system (PoC) business, meeting (Conference) business etc.In the multiway telecommunication service network, by focus on server come centralized control session signaling flow process, be responsible for authorizing each communication party medium sending right, carry out duplicating and distribution etc. in the media delivery, the described server that focuses on refers to: the Conference server (Conference Server) in the control PoC server in the PoC service network (Controlling PoC Server), the Conference business network etc.This paper will be that example is set forth problem and solution of the present invention that prior art occurs with the PoC service.
The PoC service communication system is a kind of semiduplex communication system, and system wants a plurality of users' of Control Allocation cluster conversation medium sending right, and the process of this Control Allocation medium sending right is called as right to speak control (Floor Control) in PoC service.Present PoC service is carried out the mechanism that each user seizes right to speak, the user is in speech forward direction system request floor power, system is user's floor grant of request floor power at first among the user of current participation session, and refuses the right to speak application that follow-up other user sends.Therefore, the PoC service system only transmits and enjoys right to speak user's voice stream, makes the user who participates in session can't hear other user's voice.
Wherein, each session subscriber can be own request floor power by sending the right to speak request, and the control PoC server of current sessions distributes right to speak for sending this requesting users.Session subscriber can be other user applies right to speak by sending the right to speak request also, and the information that the control PoC server of current sessions carries according to this right to speak request is for respective user is distributed right to speak.In addition, the PoC server also can initiatively distribute right to speak for each user by certain processing logic according to allocation strategy.
When the PoC server is authorized user's right to speak, the transmission right to speak is authorized (Floor granted) and is notified to UE, UE will directly send the media data of self to the PoC server then, by the PoC server media data that receives will be distributed to each UE of current sessions again.Such as: in the speech business of PoC, in case after UE received Floor granted notice, the microphone of this PoC terminal promptly was opened, thereby this PoC terminal begins the various speech datas that microphone receives are passed to the PoC server.
But, also have some problems in the present right to speak control.Especially for those by the PoC server initiatively floor grant the user or by other user for for the user of its request right to speak, might not accept current right to speak of authorizing after these users are awarded the right to speak, also might not carry out the preparation of media data.But at this moment, the media data from this user has been distributed to each session subscriber by the PoC server.These media datas are likely the data of some no practical significances, thereby will waste the system transmissions resource.Such as: when a certain UE user does not carry out the preparation of speech, this UE receives Floor granted notice suddenly, its microphone is opened automatically, this moment the voice that receive of microphone be likely noise that some are outside or from the user with the irrelevant voice of session speech.
Present this medium sending right controlling mechanism not only can cause transmission resource waste, also make troubles to the user probably, such as: in video session, when certain user do not carry out the preparation of video speech, when not properly dressed, but accident obtains right to speak, the camera of this UE will be activated, and the image of this user's negligence of dress will be delivered to each user of session, thereby cause how-do-you-do.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The medium sending right that the invention discloses a kind of multiway telecommunication service is determined method, its main design philosophy is: UE is receiving after medium sending right authorizes notice, judge whether to accept this medium sending right, if accept, the media data that just begins transmission user is given the server that focuses on of current business session; The current business session focus on server after authorizing the user media transmission route, judge whether UE accepts this medium sending right, if UE accepts, then begin from this UE receiving media data and be distributed to each other UE of current business session.
Here, focus on the method that server judges whether UE accepts medium sending right and have two kinds substantially: one, according to from UE be used to indicate whether that the notice of accepting medium sending right judges; This notice that is used to indicate whether to accept medium sending right comprises that indication accepts the notice of medium sending right and the notice that the indication refusal is accepted medium sending right; Two, whether control PoC server basis receives from the media data of UE in default timing cycle and judges.
Wherein, medium sending right is often referred to right to speak (Floor), in the future development stage of multiway telecommunication service, the medium sending right of other type also may occur, also all belongs to the category of medium sending right of the present invention.The present invention can be applicable in right to speak control (Floor Control) flow process of multiway telecommunication services such as PoC service and Conference business.In PoC service, focusing on server is exactly the control PoC server of current PoC session, and in the Conference business, focusing on server is exactly the Conference server of current C onference session.The present invention focuses on the server that server can be used to focus on the multiway telecommunication service session for any, development along with multiway telecommunication service, occur to remove control PoC server, the Conference server other probably and be used to focus on the server of service conversation, they also all belong to the present invention and focus on the server category.
Right to speak control flow with more typical PoC service is an example below, and the inventive method is elaborated.In PoC session, UE comes and control PoC server interaction session control signaling and media data by the participation PoC server under self, wherein participates in the outbreak that mainly runs up of PoC server and uses.And the inventive method relates to the improvement to control PoC server process, describe for simplifying, among the embodiment described herein, the relevant treatment that participates in the PoC server is omitted, also not shown participation PoC server in the accompanying drawing, processing entities only comprises: UE and control PoC server.
Fig. 1 is the inventive method one preferred embodiment handling process schematic diagram.In the present embodiment, control PoC server according to from UE be used to indicate whether that the notice of accepting right to speak judges whether UE accepts right to speak.As shown in Figure 1, set up after the PoC session between UE and the control PoC server, the concrete processing comprises:
Step 101: control PoC server is distributed to UE with right to speak, send right to speak to UE and authorize (Floor granted) notice, send right to speak to each other UE of current PoC session and take (Floor taken) notice, and beginning to receive the notice that is used to indicate whether to accept right to speak from UE, this is used to indicate whether that the notice of accepting right to speak can accept the notice of right to speak or the notice that the indication refusal is accepted right to speak for indication.
Step 102:UE judges whether to accept current right to speak of authorizing, if accept, then execution in step 103; Otherwise execution in step 103 '.
Here, will point out the user whether will accept this right to speak after authorizing notice from the right to speak of control PoC server, receive then, judge according to this operational order whether the user accepts this right to speak from user's operating command when UE receives.Mode that can man-machine interface such as: UE shows to the user and currently is awarded the right to speak that the user can indicate whether to accept this right to speak by this man-machine interface input operation order.
At this moment, UE is transmission of media data not, has only as the user and determines that will accept right to speak just understands transmission of media data, thereby avoid sending invalid media data under the offhand situation of user.
Step 103:UE transmission indication is accepted being notified to of right to speak and is controlled the PoC server, and the media datas such as audio/video that self receives are transferred to control PoC server.
Step 104: control PoC server receives after the described indication of step 103 accepts the notice of right to speak, judges that UE accepts current right to speak of authorizing, and begins from the UE receiving media data and is distributed to each other UE of current PoC session, finishes current handling process.
Step 103 ': UE transmission indication refusal is accepted being notified to of right to speak and is controlled the PoC server.
After the described indication refusal of step 104 ': control PoC server receive step 103 ' is accepted the notice of right to speak, judge the current right to speak of authorizing of UE refusal acceptance, release steps 101 is distributed to the right to speak of this UE, send right to speak free time (Floor free) notice to each UE of current PoC session then, finish current handling process.
Consider that UE may indicate whether that the notice of accepting right to speak successfully is sent to control PoC server with being used to, entire process flow process of the present invention can't be gone on, so also can further in control PoC server, timer be set, in step 101, control PoC server further starts this timer, when receiving when accepting the notice of right to speak from the indication of UE, this timer will restart.This control PoC server will judge whether to receive the notice of accepting right to speak from the indication of UE in the timing cycle of default timer, if judge that then UE accepts right to speak, execution in step 104; Otherwise promptly timer expiry judges that then UE refuses to accept right to speak, execution in step 104 '.
Fig. 2 is another preferred embodiment handling process schematic diagram of the inventive method.In the present embodiment, control PoC server will be provided with timer like this according to whether receiving from the media data of UE to judge whether UE accepts right to speak in default timing cycle in control PoC server.As shown in Figure 2, set up after the PoC session between UE and the control PoC server, the concrete processing comprises:
Step 201: control PoC server is distributed to UE with right to speak, sends right to speak to UE and authorizes notice, sends right to speak to each other UE of current PoC session and takies notice, and start set timer, begins to receive the media data from UE.Here, when the media data that receives from UE, this timer will restart.
Step 202:UE judges whether to accept current right to speak of authorizing, if accept, then execution in step 203; Otherwise execution in step 203 '.The judgement of this step is identical with the described determination methods of step 102, just no longer describes in detail here.
The media datas such as audio/video that step 203:UE begins that self is received are transferred to control PoC server.Control PoC server receives media data from UE in the timing cycle of default timer after, judge that UE accepts current right to speak of authorizing, begin to be distributed to from the media data of UE each other UE of current PoC session, finish current handling process.
Step 203 ': control PoC server does not receive the media data from UE all the time in the timing cycle of default timer, it is timer expiry, judge that then UE refuses to accept right to speak, release steps 201 is distributed to the right to speak of this UE, send the idle notice of right to speak to each UE of current PoC session then, finish current handling process.
Based on the inventive method, the medium sending right that the invention allows for a kind of multiway telecommunication service is determined system, and this system comprises: UE, service conversation focus on server and medium sending right is accepted the unit.
Wherein, UE is used for authorizing notice from focusing on the transmission route of server receiving media, and authorizes when notice and send medium sending right and authorize indication and accept the unit to medium sending right receiving this medium sending right; Judge that the user accepts the current medium sending right of authorizing when receiving when the medium sending right of accepting the unit from this medium sending right is accepted indication, and the beginning transmission of media data is given and is focused on server.Focus on server and be used to judge whether UE accepts the current medium sending right of authorizing, and when judgement is accepted, receive from the media data of UE and distribute this media data.Medium sending right is accepted the medium sending right that the unit is used to receive from UE and is authorized indication, receives from user's operating command, when medium sending right is accepted in judgement, sends medium sending right and accepts indication to UE.At this moment, focus on server and can judge whether UE accepts medium sending right according to whether receiving from the media data of UE.
In addition, also can accept notice that unit output is used to indicate whether to accept medium sending right by medium sending right notifies and focuses on server UE and whether accept medium sending right.Like this, system of the present invention further comprises the medium sending right determining unit.This medium sending right determining unit is used for accepting the unit from medium sending right and receives and to be used to indicate UE whether to accept the notice of medium sending right, sends medium sending right when the notice of medium sending right is accepted in indication and determines that indication is to focusing on server receiving.This focuses on server and judges when this medium sending right is determined indication that UE accepts the current medium sending right of authorizing receiving, and begins to receive from the media data of UE and distribute this media data.
By as can be known noted earlier, focus on server and can be control PoC server or Conference server, medium sending right is often referred to right to speak.Being example with control PoC server and right to speak is below elaborated the realization of system of the present invention.
Fig. 3 forms structural representation for system of the present invention one preferred embodiment.As shown in Figure 3, comprise in the present embodiment: UE, control PoC server and medium sending right are accepted the unit.Below in conjunction with Fig. 3 a deterministic process of right to speak is set forth, thereby system works principle of the present invention is described further.
At first, control PoC server is determined to authorize the UE right to speak, then sends right to speak and authorizes and be notified to UE.UE sends right to speak immediately and authorizes indication and accept the unit to medium sending right.
Then, medium sending right is accepted the unit will and receive user's operating command to user's display reminding information, judge according to this operational order whether the user accepts current right to speak of authorizing, and the output right to speak is accepted indication and given UE when judging that the user accepts right to speak.UE promptly begins user's media data is passed to control PoC server after receiving right to speak acceptance indication, such as: UE receives right to speak and accepts will open microphone after the indication, begins to receive user's voice and also transmits; And not receiving right to speak when accepting indication, microphone will keep cutting out always, thereby avoid invalid voice data transmission.
At last, control PoC server will be judged that UE has accepted right to speak, thereby will distribute between each UE of current PoC session from the media data of UE when the media data that receives from UE.
On the basis of the invention described above system, also can further comprise the medium sending right determining unit.At this moment, as shown in Figure 3, medium sending right is accepted the unit after judging whether the user accepts right to speak, also further send be used to indicate whether to accept right to speak be notified to the medium sending right determining unit.This is used to indicate whether that the notice of accepting right to speak can accept the notice of right to speak or the notice that right to speak is accepted in indication for the indication refusal.The medium sending right determining unit receives judges when indicating the notice of accepting right to speak that UE accepts current right to speak of authorizing, and the transmission right to speak determines to indicate the server to control PoC.This control PoC server determines that the indication back judges that UE accepts right to speak receiving this right to speak, thereby begins from the UE receiving media data and be distributed to each UE of current PoC session; Otherwise,, and send the unaccepted indication of right to speak to controlling the PoC server if the medium sending right determining unit is judged the current right to speak of authorizing of UE refusal when receiving the notice of indicating the refusal right to speak.This control PoC server is receiving the unaccepted indication of this right to speak back judgement UE refusal right to speak, thereby discharges the right to speak of distributing to this UE.Here, the medium sending right determining unit will can not send right to speak when indication refusal is accepted the notice of right to speak and determine indication receiving, thereby control PoC server will judge that UE does not accept right to speak and do not carry out media data to transmit.
In addition, system of the present invention also can further comprise timer.As shown in Figure 3, this timer is connected with control PoC server, whether whether control PoC server can according to receiving the overtime indication of self-timer to judge whether to exceed default timing cycle, thereby can judge to receive from the media data of UE in timing cycle or do not receive from the right to speak of medium sending right determining unit and determine indication.When system of the present invention does not comprise the medium sending right determining unit,, judge that then UE accepts current right to speak of authorizing if control PoC server receives from the media data of UE and do not receive overtime indication; Otherwise judge that UE refuses to accept this right to speak.When system of the present invention comprises the medium sending right determining unit, if control PoC server receives from the right to speak of medium sending right determining unit determine indication and do not receive overtime indication, judge that then UE accepts current right to speak of authorizing; Otherwise judge that UE refuses to accept this right to speak.
Among the above embodiment, medium sending right is accepted the unit and can or be integrated among its UE that connects for the independent entity that is provided with; The medium sending right determining unit also can be the independent entity that is provided with or is integrated in focusing in the server that it connects; Timer also can be the independent entity that is provided with or is integrated in focusing in the server that it connects.
In sum, use the inventive method and system, can solve the problem that exists in the present multiway telecommunication service medium sending right control technology, have only when the user who is awarded medium sending right determines to accept medium sending right, this user's media data just can be received by UE and be distributed to other UE via focusing on server, thereby avoided the transmission of inactive media data substantially, improved the system transmissions resource utilization, and brought more excellent business experience to the user.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all be included in protection scope of the present invention.
