Description

A kind of polymorphic type medium sending right medium priority processing method and device

Technical field

The present invention relates to multi-party communication, refer to polymorphic type medium sending right medium priority processing method and device in multi-party communication especially.

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 is adjudicated above-mentioned request and is permitted, this communication user could send media stream data by other communication users in this group, and the control point can be server such as PoC server, Conference server etc.

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 has the processing to the medium sending right of sound-type; Suppose that certain group comprises that two users are user 1 and user 2, user's 1 request speech, existing concrete the processing may further comprise the steps:

Step 100: user 1 sends medium sending right request (Floor Request) message by user terminal 1 (UE1) to 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 of permission medium sending right (Floor Grant) message permission UE1 to UE1, and the UE of other users in the group of UE1 place sends and accepts medium sending right (Floor Taken) message and authorized UE1 to notify the current medium sending right of described other users.

Here suppose that UE1 place group only comprises user 1 and user 2, the UE of other users in the group of then described UE1 place is exactly user 2 user terminal UE2.

Step 104b:UE1 sends Media Stream (Media Burst) data to UE2.

Step 105b～step 106b: the priority-level of supposing user 2 is higher than user's 1, if at UE1 when UE2 sends media stream data, user 2 by UE2 to server send FloorRequest message rob for the time being server through judgement after, agree to authorize UE2 medium sending right.

Step 107b～step 108b: server sends to UE1 and recalls medium sending right (FloorRevoke) message, requires the user 1 who is making a speech that medium sending right is discharged, and UE1 sends medium sending right to server and discharges (Floor Release) message.

Step 109b～step 110b: server sends the medium sending right application that Floor Grant message is permitted UE2 to UE2, and has authorized UE2 to UE1 transmission Floor Taken message with the current medium sending right of notice UE1; UE2 sends media stream data to UE1.

In the existing media sending authority processing method, server is only controlled one type medium sending right according to preset strategy, robbing temporary, mainly control the authorisation process problem of medium sending right at user's User Priority by definition, promptly receive the medium sending right request of the user A that user priority levels is high when server, even the current user of having B makes a speech, but if the user priority levels of user B is lower than user A's, server also will interrupt the speech of user B and authorize user priority levels high user B medium sending right.

Development along with broadband network, mobile communication 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.

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 control to multiple medium sending right, and the processing method that prior art is carried out the medium sending right mandate according to User Priority simply can not satisfy professional demand.One piece of the applicant has provided polymorphic type media sending authority processing method and device in first to file, but at this in first to file, the mandate to the dissimilar medium sending right that has priority does not provide detailed protocol.

Concentrated granted unit can receive that also one is authorized indication just to handle one, if promptly authorize, then sends and agrees that the Authorization result of authorizing is to sending module or insert formation; If refusal, the Authorization result that then sends the refusal mandate is to sending module.

Polymorphic type medium sending right medium priority processing unit of the present invention can be arranged on the control point that is used for multi-party communication is carried out unified management.

Fig. 2 d is polymorphic type medium sending right medium priority process flow figure of the present invention, and in the multi-party communication system, the inventive method mainly may further comprise the steps:

Step 200: be used for that the control point that multi-party communication carries out unified management is set in advance medium sending right type and the corresponding relation of authorizing priority-level.

Step 201～step 203: after the control point receives medium sending right request from user terminal, judge whether the mandate priority-level of the medium sending right that carries in this medium sending right request is higher than the mandate priority-level of the medium sending right of the same type of having authorized in the current system, if be higher than, then recall current similar medium sending right of having authorized and authorize the medium sending right that receives; Otherwise, continue to carry out current medium sending right of having authorized.

Need to prove that before step 201～step 203, this method also comprises: the medium sending right that whether has request in the medium sending right of having authorized in the system is judged at the control point, if exist, execution in step 201～step 203 then, otherwise, process ends behind the medium sending right of authorization requests.

Introduce the situation of priority-level of authorizing respectively below in conjunction with embodiment by User Priority or medium sending right type priority level or User Priority and media transmission priority decision.

First kind of situation authorizes priority-level to be determined by User Priority.

Because the present invention is based in the application of polymorphic type medium sending right the processing to priority, in a medium sending right request, carry the medium sending right of one or more types, therefore, the present invention said User Priority has comprised the User Priority of each medium sending right that this user has the right to apply for.The medium sending right of having the right to apply for such as user A comprises medium sending right a, medium sending right b and medium sending right c, and the user priority levels of each medium sending right is as shown in table 1:

Table 1

In each medium sending right that the user has the right to apply for, there is different user priority levels, so, can be with each medium sending right User Priority separately respectively as the mandate priority of each medium sending right in the medium sending right request that this user initiated; Also can adopt user priority levels is minimum in described each medium sending right User Priority mandate priority as each medium sending right in the medium sending right request that this user initiated; Can also adopt user priority levels is the highest in described each medium sending right User Priority mandate priority as each medium sending right in the medium sending right request that this user initiated;

Each medium sending right of having the right to apply for as the user has identical user priority levels, then can think the User Priority of arbitrary medium sending right in each medium sending right that the mandate priority of the medium sending right in the medium sending right request that this user initiated has the right to apply for for this user.

Such as: minimum rank is 3 grades in the user priority levels of several medium sending right types that user's first can be applied for; And minimum rank is 2 grades in the user priority levels of several medium sending right types that user's second can be applied for; If be provided with the control point according to the minimum rank of each medium sending right as User Priority, then carry out priority ratio than the time, User Priority that user's first is judged at the control point is lower than user's second, the medium sending right application of priority treatment user's first.

Fig. 3 is the flow chart of polymorphic type medium sending right medium priority Processing Example one of the present invention, adopts User Priority as authorizing priority among the embodiment one, supposes that in multi-party communication system user 1 and user 2 belong to together in the group; The medium sending right that user 1 has the right to apply for is medium sending right B; The medium sending right that user 2 has the right to apply for is medium sending right A and medium sending right B; And the user priority levels that sets in advance user 1 medium sending right B correspondence in server is 2 grades, and the user priority levels of user 2 medium sending right A correspondence is that 1 grade, the user priority levels of medium sending right B correspondence are 3 grades; Here suppose that the more little priority-level of numeral is high more, the user priority levels of promptly described user's 1 medium sending right B is higher than the user priority levels of user 2 medium sending right B.

Among Fig. 3, user 1 initiates medium sending right B request and obtains the authorization to server by UE1, shown in step 300～step 304 among Fig. 3, only exist the step 100～step 104b (not comprising step 102a) in one type the medium sending right application method in full accord among specific implementation and Fig. 1.Shown in step 305, suppose at UE1 that during UE2 sends Media Stream B data user 2 initiates medium sending right A and medium sending right B request (FloorA﹠amp by UE2 to server; When B Request) message obtained Media Stream A data and the transmission route of Media Stream B data with request, present embodiment may further comprise the steps the processing of priority:

Step 306: server is judged the FloorA﹠amp from UE2 according to the dissimilar medium sending rights of self presetting and the corresponding relation of user priority levels; The user priority levels of carrying medium sending right B in the B Request message is lower than the user priority levels of the medium sending right B of the current UE1 that has authorized; And there is not medium sending right A in the current medium sending right of having authorized.

Step 307～step 309: server is agreed the medium sending right A of authorized user 2 requests, and specific implementation and step 102b～104b are in full accord, no longer repeat here.

Need to prove, do not influence mutually between the medium sending right A of this moment and the medium sending right B and do not have a sequencing.

Step 310: server sends refusal medium sending right B (FloorB Reject) message to UE2 and authorizes with refusal.This step can be changed execution sequence with step 307～step 309; This step also can be omitted.

In the present embodiment, what describe is the situation that the user applies for a kind of medium sending right successively, when the user applies for simultaneously and require to obtain the mandate of multiple medium sending right simultaneously, when requiring to obtain the mandate of medium sending right A and medium sending right B simultaneously such as user 1, judgement wherein exists a kind of medium sending right such as medium sending right B not to be authorized to if the control point is according to User Priority, then to refuse all medium sending rights simultaneously be medium sending right A and medium sending right B or refusal medium sending right B at the control point, authorizes medium sending right A also to keep this mandate earlier.After medium sending right B is authorized to, sends to this user 1 at the same time and authorize medium sending right A and medium sending right B response.

In addition, in the present embodiment, adopt user priority levels is minimum in described each medium sending right User Priority mandate priority, then from the FloorA﹠amp of UE2 as each medium sending right in the medium sending right request that this user initiated if set in advance; Medium sending right A that carries in the B Request message and the user priority levels of medium sending right B are 3 grades, and so, user 2 medium sending right A is authorized to equally, and medium sending right B is rejected equally;

Adopt user priority levels is the highest in described each medium sending right User Priority mandate priority if set in advance, then from the FloorA﹠amp of UE2 as each medium sending right in the medium sending right request that this user initiated; Medium sending right A that carries in the B Request message and the user priority levels of medium sending right B are 1 grade, so, user 2 medium sending right A is authorized to equally, and this moment, because the user priority levels of user 2 medium sending right B is higher than the user priority levels of user 1 medium sending right B, therefore, user 2 medium sending right B is authorized to.

Here need to prove that non-formation and formation mode can be adopted to the processing of polymorphic type medium sending right in the control point, wherein, non-formation mode is meant after the medium sending right request is received at the control point and handles at once; And after the formation mode is meant that the medium sending right request is received at the control point, the medium sending right that carries in this medium sending right request can be deposited in the formation as waiting successively according to certain principle, afterwards by the control point according to preset strategy as regularly or be authorized medium sending right and discharge triggering etc. a collection of (specified quantity) medium sending right in the formation is dispatched processing.The medium sending right processing scheme of concrete formation mode can repeat no more here referring to being correlated with in first to file of the applicant.

Embodiment shown in Figure 3 is based on the User Priority processing method that adopts non-formation mode in the processing of polymorphic type medium sending right, adopts the User Priority of formation mode to handle in handling for the polymorphic type medium sending right, can be referring to shown in Figure 4.

Fig. 4 is the flow chart of polymorphic type medium sending right medium priority Processing Example two of the present invention, adopts User Priority as authorizing priority among the embodiment two, supposes that in multi-party communication system user 1 and user 2 belong to together in the group; The medium sending right that user 1 has the right to apply for comprises medium sending right A and medium sending right B; The medium sending right that user 2 has the right to apply for comprises medium sending right A and medium sending right B; And the user priority levels that sets in advance user 1 medium sending right correspondence in server is that 1 grade, the user priority levels of medium sending right B correspondence are 2 grades, and the user priority levels of user 2 medium sending right A correspondence is that 2 grades, the user priority levels of medium sending right B correspondence are 1 grade; Here suppose that the more little priority-level of numeral is high more, be the user priority levels that the user priority levels of described user's 1 medium sending right A is higher than user 2 medium sending right A, the user priority levels of described user's 1 medium sending right B is lower than the user priority levels of user 2 medium sending right B.Present embodiment may further comprise the steps the processing of priority:

Step 400～step 402: user 1 sends medium sending right A and medium sending right B request message by UE1 to server, user 2 sends medium sending right A and medium sending right B request message by UE2 to server, and server is dispatched processing to the medium sending right in the default formation.

In the present embodiment, suppose in server a default formation, server deposits medium sending right A and the medium sending right B that carries in this request in the formation in after receiving request from UE1; Server deposits medium sending right A and the medium sending right B that carries in this request in the formation in after receiving the request of initiating from UE2; And server is regularly dispatched processing to the specified quantity of storing in the formation as four medium sending rights.

Scheduling is handled and comprised: server is according to the default dissimilar medium sending rights and the corresponding relation of user priority levels, it is the medium sending right A corresponding priorities rank that user 1 medium sending right A corresponding priorities is superior to user 2, judge the medium sending right A that agrees authorized user 1, till user 1 discharges medium sending right A, agree the medium sending right A of authorized user 2 again; Server is according to the corresponding relation of default medium sending right and User Priority, it is the medium sending right B corresponding priorities rank that user 1 medium sending right B corresponding priorities rank is lower than user 2, judge the medium sending right B that agrees authorized user 2, till user 2 discharges medium sending right B, agree the medium sending right B of authorized user 1 again.

Step 403～step 405: server sends FloorA Grant message to UE1, sends FloorA Taken message to UE2, and UE1 sends Media Stream A data to UE2.

Step 406～step 408: server sends FloorB Grant message to UE2, sends FloorB Taken message to UE1, and UE2 sends Media Stream B data to UE1.

Step 409:UE1 sends medium sending right A to server and discharges (FloorA Release) message.

Step 410～step 412: server is agreed the medium sending right A of authorized user 2, sends FloorA Grant message to UE2, sends FloorA Taken message to UE1, and UE2 sends Media Stream A data to UE1.

Step 413:UE2 sends medium sending right B to server and discharges (FloorB Release) message.

Step 414～step 416: server is agreed the medium sending right B of authorized user 1, sends FloorB Grant message to UE1, sends FloorB Taken message to UE2, and UE1 sends Media Stream B data to UE2.

Need to prove, step 403～step 405, and can not have sequencing between step 406～step 408.

In the present embodiment, if the user applies for simultaneously and when requiring to obtain the mandate of multiple medium sending right simultaneously, if drawing after handle according to User Priority scheduling at the control point wherein exists a kind of medium sending right not to be authorized to, then all medium sending rights are refused at the control point simultaneously, only after each medium sending right that this user applies for simultaneously all is authorized to, just authorize this application; Perhaps, with the current medium sending right that has been authorized to medium sending right of the same type, authorize current medium sending right of being authorized and be not medium sending right of the same type in the medium sending right of rejecting; Perhaps, preserve carry in the described medium sending right request with the current medium sending right that has been authorized to medium sending right of the same type, authorize current medium sending right of being authorized and be not medium sending right of the same type, after described current medium sending right of having authorized discharges, further authorize carry in described this medium sending right request with the current medium sending right that has been authorized to medium sending right of the same type.

Second kind of situation authorizes priority-level to be determined by medium sending right type priority level.

Medium sending right type priority level is meant the priority of the medium sending right of variant type, and is irrelevant with the user.In multi-party communication system, server sets in advance the priority-level of self treatable all kinds medium sending right.Such as, the priority-level of supposing medium sending right A is 1 grade, the priority-level of medium sending right B is 2 grades, when medium sending right A is authorized to, the medium sending right B that is authorized to temporarily can be kept, and perhaps directly stops this medium sending right B; After medium sending right A discharged, the mandate with the medium sending right B that keeps sent to the user again;

The priority of medium sending right can be used for medium sending right is carried out sequential processes, perhaps interactional medium sending right is carried out sequential processes.Such as, the medium sending right that priority-level is high will preferentially be authorized; For interactional medium sending right, if a medium sending right is authorized to, receive another medium sending right request again, then can determine whether needs are recalled the current media transmission route, and authorize medium sending right in the back application according to medium sending right type priority level in the back application.The medium sending right type priority level rank of each medium sending right is as shown in table 2:

Medium sending right	Medium sending right type priority level rank
Medium sending right	Medium sending right type priority level rank	Medium sending right a	1 grade
Medium sending right b	3 grades	Medium sending right a	1 grade
Medium sending right b	3 grades	Medium sending right c	2 grades

Table 2

The medium sending right type priority level rank of dissimilar medium sending rights can be set to identical.In realization, do not influence mutually and do not have an order of mandate successively such as: two kinds of medium sending rights, be that the control point can be authorized two kinds of medium sending rights simultaneously, the user can receive two kinds of media stream datas simultaneously, so, it is identical the medium sending right type priority level rank of these two kinds of medium sending rights can be set.

Fig. 5 is the flow chart of polymorphic type medium sending right medium priority Processing Example three of the present invention, adopts medium sending right type priority level as authorizing priority among the embodiment three, supposes that in multi-party communication system user 1 and user 2 belong to together in the group; The medium sending right type priority level rank that sets in advance medium sending right A at server is 2 grades, the medium sending right type priority level rank of medium sending right B is 1 grade, and medium sending right A and medium sending right B can not be authorized to simultaneously, weigh and have the video power of voice such as voice; Here suppose that the more little priority-level of numeral is high more, the medium sending right type priority level of promptly described medium sending right B is superior to the medium sending right type priority level rank of medium sending right A.Present embodiment may further comprise the steps the processing of priority:

Step 500～step 504: user 1 sends FloorA Request message request application medium sending right A by UE1 to server, suppose that server judgement user 1 has the right to apply for medium sending right A and uncommitted other users that give user 1 place group of current media transmission route, then server authorizes user 1 obtains medium sending right A; Server sends FloorA Grant message to UE1, sends FloorA Taken message to UE2, and UE1 sends Media Stream A data to UE2.

Step 505: during UE2 sent Media Stream A data, user 2 sent FloorB Request message request application medium sending right B by UE2 to server at UE1.

Step 506～step 508: server is according to default dissimilar medium sending rights and other corresponding relation of medium sending right type priority level level, judge the medium sending right type priority level rank that is superior to the current medium sending right A that has authorized from the medium sending right type priority level of the medium sending right B of UE2, and medium sending right A and medium sending right B can not be authorized to simultaneously, server sends FloorA Revoke message to UE, and UE1 sends FloorA Release message to server and discharges medium sending right A.

Step 509～step 511: server sends FloorB Grant message to UE2, sends FloorB Taken message to UE1, and UE2 sends Media Stream B data to UE1.

Fig. 6 is the flow chart of polymorphic type medium sending right medium priority Processing Example four of the present invention, and the same medium sending right type priority level that adopts supposes that as authorizing priority user 1 and user 2 belong to together in the group in multi-party communication system among the embodiment four; The medium sending right type priority level rank that sets in advance medium sending right A at server is 1 grade, the medium sending right type priority level rank of medium sending right B is 2 grades, and medium sending right A and medium sending right B can not be authorized to simultaneously, and the medium sending right type priority level of medium sending right A is superior to the medium sending right type priority level rank of medium sending right B.Present embodiment may further comprise the steps the processing of priority:

Step 600～step 602: user 1 sends Floor[A﹠amp by UE1 to server; B] Request message request medium sending right A and medium sending right B; Server is according to medium sending right A and medium sending right B and other corresponding relation of medium sending right type priority level level of setting in advance, and medium sending right A and medium sending right B can not be authorized to simultaneously, judge and license to the high medium sending right A of medium sending right type priority level rank, server sends FloorA Grant message to UE1.

Step 603～step 604: server sends to UE2 and accepts medium sending right A and medium sending right B (Floor[A﹠amp; B] Taken) message, UE1 sends the data of Media Stream A to UE2.

In the present embodiment, server sends the response of permission medium sending right to UE1 successively, and still other UE in the group of UE1 place send and accept medium sending right A and medium sending right B response simultaneously.

Step 605～step 606: after server receives FloorA Release message from UE1, send FloorB Grant message to UE1.

Step 607:UE1 sends the data of Media Stream B to UE2.

Among the embodiment four, when the user applied for a plurality of dissimilar and medium sending right that can not authorize simultaneously simultaneously, server can utilize the medium sending right type priority level rank right that low order is authorized medium sending right from the rank height to rank that sets in advance.

Fig. 5 and embodiment shown in Figure 6 are based on the medium sending right type priority level processing method that adopts non-formation mode in the processing of polymorphic type medium sending right, for adopting the medium sending right type priority level of formation mode to handle in the processing of polymorphic type medium sending right, can be referring to Fig. 7 and shown in Figure 8.

Fig. 7 is the flow chart of polymorphic type medium sending right medium priority Processing Example five of the present invention, and the same medium sending right type priority level that adopts supposes that as authorizing priority user 1 and user 2 belong to together in the group in multi-party communication system among the embodiment five; The medium sending right type priority level rank that sets in advance medium sending right A at server is 2 grades, the medium sending right type priority level rank of medium sending right B is 1 grade, and medium sending right A and medium sending right B can not be authorized to simultaneously, and the medium sending right type priority level rank of medium sending right A is lower than the medium sending right type priority level rank of medium sending right B.Present embodiment may further comprise the steps the processing of priority:

Step 700～step 702: user 1 sends medium sending right B request message by UE1 to server, and user 2 sends medium sending right A request message by UE2 to server, and server is dispatched processing to the medium sending right in the default formation.

In the present embodiment, suppose in server a default formation, server deposits the medium sending right B that carries in this request in the formation in after receiving request from UE1; Server deposits the medium sending right A that carries in this request in the formation in after receiving the request of initiating from UE2; And server is regularly dispatched processing to the specified quantity of storing in the formation as two medium sending rights.

Scheduling is handled and comprised: server is according to default medium sending right and other corresponding relation of medium sending right type priority level level, it is the medium sending right type priority level rank that the medium sending right type priority level of user 1 medium sending right B correspondence is superior to user 2 medium sending right A correspondence, judge the medium sending right B that agrees authorized user 1, till user 1 is sent completely Streaming Media A data, agree the medium sending right A of authorized user 2 again.

Step 703～step 705: server sends FloorB Grant message to UE1, sends FloorB Taken message to UE2, and UE1 sends Media Stream B data to UE2.

Step 706～step 707:UE1 sends FloorB Release message to server, and server sends medium sending right B free time (FloorB Free) message to UE2.

Step 708～step 710: server sends FloorA Grant message to UE2, sends FloorA Taken message to UE1, and UE2 sends Media Stream A data to UE1.

Fig. 8 is the flow chart of polymorphic type medium sending right medium priority Processing Example six of the present invention, and the same medium sending right type priority level that adopts supposes that as authorizing priority user 1 and user 2 belong to together in the group in multi-party communication system among the embodiment six; The medium sending right type priority level rank that sets in advance medium sending right A at server is 2 grades, the medium sending right type priority level rank of medium sending right B is 1 grade, and medium sending right A and medium sending right B can not be authorized to simultaneously, and the medium sending right type priority level rank of medium sending right A is lower than the medium sending right type priority level rank of medium sending right B.Present embodiment may further comprise the steps the processing of priority:

Step 800～step 801: user 1 sends medium sending right A request message by UE1 to server, and server is dispatched processing to the medium sending right in the default formation.

In the present embodiment, suppose in server a default formation, after server received request from UE1, depositing in the medium sending right A that carries in this request in the formation and supposing only had a medium sending right at this moment in this formation; Server is regularly dispatched processing to the specified quantity of storing in the formation as two medium sending rights.

Scheduling is handled and is comprised: owing to only have a medium sending right in the described formation this moment, so server is judged the medium sending right A that agrees authorized user 1.

Step 802～step 804: server sends FloorA Grant message to UE1, sends FloorA Taken message to UE2, and UE1 sends Media Stream A data to UE2.

Step 805: during UE2 sent Media Stream A data, user 2 sent FloorB Request message request application medium sending right B by UE2 to server at UE1.

Step 806: server deposits the medium sending right B that carries in this request in the formation in after receiving request from UE2, and having two medium sending rights in described formation this moment is medium sending right A and medium sending right B; Server is regularly dispatched processing to the specified quantity of storing in the formation as two medium sending rights.

Scheduling is handled and comprised: server is according to default medium sending right and other corresponding relation of medium sending right type priority level level, be that medium sending right B corresponding priorities is superior to medium sending right A corresponding priorities rank, judge the medium sending right B that agrees authorized user 2 and recall the user 1 current medium sending right A that is authorized to.

Step 807～step 809: server sends to UE1 and recalls medium sending right A (FloorARevoke) message, and UE1 sends FloorA Release message to server; Server sends Floor Free message to UE2.

Step 810～step 812: server sends FloorB Grant message to UE2, sends FloorB Taken message to UE1, and UE2 sends Media Stream B data to UE1.

From embodiment six as seen, even medium sending right in the back application, as long as the medium sending right type priority level of this medium sending right is superior to the medium sending right that has been authorized to in first to file, server will be recalled current medium sending right of having authorized, and authorize the medium sending right in the back application.

More than two kinds of situations, iff considering that User Priority decides mandate priority, then think to have equal priority between the dissimilar medium sending right, in such cases, handle according to the sequencing that the user files an application; Iff considering medium sending right type priority level decision mandate priority, think that then the user has same subscriber priority, in such cases, handle according to the sequencing that the user files an application.

The third situation authorizes priority-level by User Priority and the decision of medium sending right type priority level.

At first need to be provided with priority treatment power, promptly pay the utmost attention to and adopt the User Priority decision to authorize priority, still adopt the decision of medium sending right type priority level to authorize priority.Priority treatment power can be provided with by operator, also can be provided with by the user.Such as, in the PoC system, the user can be provided with and revise by the interface with XML (extensible Markup Language) document management server (XDMS), and detailed process is same as the prior art.

If User Priority has priority treatment power, then mandate is judged according to User Priority in the control point after receiving the medium sending right application, and first kind of situation is in full accord in specific implementation and the literary composition; Only between the identical user applies of User Priority, further judge mandate according to medium sending right type priority level, second kind of situation is in full accord in specific implementation and the literary composition;

If medium sending right type priority level has priority treatment power, then mandate is judged according to medium sending right type priority level in the control point after receiving the medium sending right application, and second kind of situation is in full accord in specific implementation and the literary composition; Only when medium sending right type priority level is identical, further judge mandate according to User Priority, first kind of situation is in full accord in specific implementation and the literary composition.

In other words, when authorizing priority by User Priority and the decision of medium sending right type priority level, be according to the priority treatment power that sets in advance, adopt priority to judge earlier with priority treatment power, when this priority with priority treatment power can not be judged Authorization result, adopt the priority that does not have priority treatment power further to judge again.

The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
