Embodiment

In order to solve the problem of trunked communication system diversification, implementation column of the present invention provides a kind of cluster right of speech method for pre-emptively, device and system, in group, the high user of cluster priority can initiate right of speech and seize flow process in the time that other user talks, and obtain right of speech and become user, or seizing the right of speech that user initiates new business seizes, the multiple business while also deposits, every kind of corresponding right of speech user of business.Make the application of cluster communication system more flexible, diversification.

Hereinafter in connection with accompanying drawing, embodiments of the invention are elaborated.It should be noted that, in the situation that not conflicting, the combination in any mutually of the feature in embodiment and embodiment in the application.

First by reference to the accompanying drawings, embodiments of the invention one are described.

The embodiment of the present invention provides a kind of cluster right of speech method for pre-emptively, make group system based on broadband network of future generation in group-calling process, in realization group, the high user of User Priority can seize active user's right of speech function, meets cluster client multiple demands.

Use embodiments of the invention to complete flow process that cluster right of speech seizes as shown in Figure 1, comprising:

Step 101, cluster listen user to initiate RRC connection process of establishing, send right of speech seize request message to cluster core net, and right of speech is seized in application;

In this step, cluster listens user to initiate RRC connection process of establishing, and application right of speech is seized.

Preferred described cluster listens user to be specially subscriber equipment (UE), UE described in this step sends right of speech by Non-Access Stratum (NAS) message to described cluster core net and seizes request message, carries the global unique temporary identity (GUTI) of group identification (Group ID) and described UE in described NAS message.For convenience of describing, be hereinafter called and seize UE listen user concurrent to play UE that right of speech seizes as cluster, will be called and be preempted UE as the current user's of saying UE.

This step idiographic flow as shown in Figure 2, seize UE and first set up RRC connection to eNB (evolved Node B) request, eNB sets up after RRC successful connection for seizing UE, seize UE and seize request message by NAS message to cluster core net transmission right of speech, in message, carry group identification G roup I D, the mark GUTI (mobile ident ity) of UE.

Preferably, the right of speech relating in this step is seized request message and is specially request and seizes the right of speech of right of speech of the business different from current business and seize request message.

Step 102, cluster core net receive cluster and listen the right of speech that user sends to seize request message;

In this step, cluster core net receives seizes the NAS message that UE sends, and obtains this and seize Group ID and the GUTI of UE.

Step 103, described cluster core net judge that described cluster listens user's priority;

This step is specifically related to two kinds of scenes: 1, seize UE and ask the business seized identical with the current user's of saying business; 2, seize the business that business that UE asks is different from the current user of saying.

Scene 1 specifically comprises again two kinds of situations:

Situation 1a, in synchronization or a preset time span, only receive one seize UE send right of speech seize request message;

Cluster core net directly more described cluster is listened user and the current user's of saying the interior User Priority of group, for example, after cluster core net receives that right of speech is seized request message, User Priority in the group of UE is seized in judgement, and which is higher with being preempted in the group of UE User Priority.

Situation 1b, in synchronization or a preset time span, received the right of speech that the multiple UE of seizing send and seized request message;

In the time that described cluster core net receives multiple clusters simultaneously and listens right of speech that user sends to seize request message, listen user and select the cluster that priority is the highest to listen user from described multiple clusters, then the highest cluster of more described priority is listened user and the current user's of saying priority.

In addition, seize the highest cluster of request message medium priority and listen after user selecting the current right of speech of sending, other clusters are listened according to priority height queuing of user, listen after user's release speech right until the highest cluster of described priority, select the cluster that comes head of the queue to listen user to carry out right of speech mandate.

Taking UE as example, when exist multiple UE of seizing to initiate situation about seizing simultaneously, what User Priority was the highest in selection group seizes UE, this is seized to the priority of UE and the current user's of saying (being preempted UE) priority compares.Other the UE that seizes queues up by User Priority height in group, seizes UE carry out right of speech mandate until other that select to come head of the queue as seizing of the current user of saying after UE release speech right; Or only set up dedicated bearer for the highest UE that seizes of priority, initiate for other UE that seizes seizing simultaneously, cluster core net is given and is seized UE and return to right of speech and seize refusal by NAS message.

For scene 2, also comprise two kinds of concrete conditions, be respectively:

Situation 2a, in synchronization or a preset time span, only receive one seize UE send right of speech seize request message;

The first more described cluster of cluster core net is listened user and the current user's of saying service priority, if cluster is listened customer service, priority is higher, thinks that cluster listens User Priority higher, otherwise has just thought that cluster listens User Priority lower.When the service priority of business of listening user to ask at cluster is identical with the current user's of saying service priority, further relatively cluster is listened user and the current user's of saying the interior concrete manner of comparison reference case of the User Priority 1a of group, is not repeated.

Situation 2b, in synchronization or a preset time span, received the right of speech that the multiple UE of seizing send and seized request message;

In the time that described cluster core net receives multiple clusters simultaneously and listens right of speech that user sends to seize request message, listen user and select the cluster that service priority is the highest to listen user from described multiple clusters, or select the identical cluster of service priority to listen the interior the highest cluster of User Priority of group in user to listen user to listen user as the highest cluster of priority.

Then the highest cluster of more described priority is listened user and the current user's of saying priority, concrete comparative approach.

Taking UE as example, when exist multiple UE of seizing to initiate situation about seizing simultaneously, select priority the highest seize UE, this is seized to the priority of UE and the current user's of saying (being preempted UE) priority compares.Other seize UE according to priority height queue up, seize UE until other that select to come head of the queue as seizing of the current user of saying after UE release speech right and carry out right of speech mandate; Or only set up dedicated bearer for the highest UE that seizes of priority, initiate for other UE that seizes seizing simultaneously, cluster core net is given and is seized UE and return to right of speech and seize refusal by NAS message.

After the judgement of this step, there will be two kinds of results.When the priority of seizing UE is when being preempted UE, proceed to step 104; When the priority of seizing UE is when being preempted UE, proceed to step 107.

Step 104, the priority during higher than the current user of saying of listening user at described cluster, discharge the current user's of saying right of speech;

In this step, the priority of listening user at described cluster is during higher than the current user of saying, described cluster core net sends right of speech releasing request message by NAS message to the current user of saying who is preempted right of speech, the described current user of saying receives after described right of speech releasing request message, return to right of speech by NAS message to described cluster core net and discharge response message, point out user to pipe down simultaneously, then described cluster core net is initiated the described current user's context releasing request of saying, reshuffle RRC, be preempted the current user's of saying of right of speech dedicated bearer described in release.

Preferably, can not be that the right of speech that new business is initiated seizes or do not allow the right of speech user of multiple business to coexist, cluster core net be initiated right of speech releasing request to the current user of saying, and discharges the dedicated signaling carrying of saying user, the current user of saying rings off, release speech right.

Taking UE as example, as shown in Figure 4, eNB reshuffles flow process to being preempted UE initiation RRC connection, by NAS message, right of speech releasing request is passed through and is preempted UE, is preempted UE and returns to right of speech release response by NAS message; Cluster core net is initiated context and is discharged flow process, discharges the dedicated bearer that is preempted UE.

Step 105, listen user to send right of speech authorization messages to described cluster;

In this step, described cluster core net listens user to initiate context Establishing process to described cluster, reshuffling described cluster listens user's RRC to connect, listen user for described cluster and set up dedicated bearer, described cluster core net, by described dedicated bearer, listens user to send right of speech authorization messages to described cluster.

Specifically as shown in Figure 3, initiate UE context Establishing process to seizing UE, reshuffle the RRC link of UE, set up dedicated bearer for seizing UE.

With step 104 simultaneously, the priority of listening user at described cluster is during higher than the current user of saying, described cluster core net listens all users of listening in the group of the current place of user to send right of speech prompting message to described cluster, notifies in described group cluster described in all users of listening to listen user to become the new current user's of saying information.For example, in cluster core net notice cluster, except other UE that seize UE, the current user of saying is transformed to and seizes UE by being preempted UE.

It should be noted that, step 104 and step 105 there is no strict time sequencing, can be according to real needs flexible configuration.In the embodiment of the present invention, only taking first completing steps 104 again completing steps 105 as example describes, concrete sequential relationship is not limited.

Step 106, described cluster core net listen all users of listening in the group of the current place of user to send right of speech prompting message to described cluster;

Step 107, the priority during lower than the described current user's of saying priority of listening user at described cluster, described cluster core net is listened user to return to right of speech to described cluster by NAS message and is seized refuse information, and discharges the RRC connection of having listened user to set up to described cluster;

In this step, if it is lower than the current user's of saying (being preempted UE) priority to seize in the group of UE User Priority, cluster core net is given and is seized UE and return to right of speech and seize refuse information by NAS message, and discharges to seizing the RRC that UE sets up and connect.

It should be noted that, corresponding with situation in step 103 2, seize if UE and set up dedicated bearer when failure, can discharge whole group calling, also can from talking right queuing queue, get the UE ranking the first, for it is set up dedicated bearer and authorizes right of speech.

A, receive that the right of speech of seizing UE seizes after message, need to carry out priority decisions judgement, if seize User Priority higher than being preempted user, initiate to seize flow process, seize UE and return to right of speech and seize refuse information otherwise give;

B, seize UE for right of speech and set up and say user's dedicated bearer, and seize successful UE to right of speech and send right of speech authorization messages;

C, release are preempted the right of speech of UE, and discharge the dedicated bearer that is preempted UE, are preempted UE and listen user from saying that user becomes;

D, listen users by sending broadcast to all in group, in group of notifications, the new user that says of user speaks.

Below in conjunction with accompanying drawing, embodiments of the invention four are described.

The flow process of a kind of cluster right of speech method for pre-emptively that as shown in figure 11, the embodiment of the present invention provides comprises:

Step 1101, cluster listen user to initiate RRC connection request, and seize to the cluster core network requests business right of speech different from current business by NAS message;

In this step, seize UE and first set up RRC connection to eNB request, eNB sets up after RRC successful connection for seizing UE, seize UE and seize request by NAS message to cluster core net transmission right of speech, the business that request right of speech is seized is different from current business, in message, carry group identification Group ID, the mark GUTI of UE, and the service identification seized of right of speech.

After step 1102, cluster core net receive that right of speech is seized request message, user's service priority is seized in judgement, if it is higher than the current user's of saying service priority to seize user's service priority, if it is high to seize the current user of saying of user's priority ratio, initiate UE context Establishing process to seizing user, reshuffle user's RRC link, set up dedicated bearer for seizing user;

If it is identical with the current user's of saying service priority to seize user's service priority, continue judgement and seize User Priority in user and the current user's of saying group, if it is high to seize user's priority, initiate UE context Establishing process to seizing user, reshuffle user's RRC link, set up dedicated bearer for seizing user;

If it is lower than the current user's of saying service priority to seize the service priority of UE, or service priority is identical, but in group, User Priority says that than current user's priority is low, cluster core net is given and is seized UE and return to right of speech and seize refusal by NAS message, and discharges to seizing the RRC that UE sets up and connect;

If exist multiple UE to initiate the situation that multi-service is seized simultaneously, select that service priority is the highest or service priority is identical but UE that User Priority is the highest, if the service priority of this UE says that than current customer service priority is high, initiate UE context Establishing process to seizing UE, reshuffle the RRC link of UE, set up dedicated bearer for seizing UE;

The UE that simultaneously initiates to seize for other ranks according to service priority and User Priority height, selects the UE that comes head of the queue to carry out right of speech mandate after the current UE release speech right of seizing; Or only set up dedicated bearer for the highest UE of priority, initiate for other UE seizing simultaneously, cluster core net is given and is seized UE and return to right of speech and seize refusal by NAS message;

Step 1103, cluster core net, for the interior all users that listen of group, comprise that the current user of saying sets up the dedicated bearer of seizing new business, for transmitting media and the signaling flow of new business.If there are multiple business to seize simultaneously, listening with setting up separately per family dedicated bearer for each business;

Step 1104, cluster core net are initiated right of speech releasing request by NAS message to current speaker, and current speaker is returned after right of speech discharges and reply, and cluster core net is initiated UE context and discharged flow process, reshuffles RRC, discharges the dedicated bearer of speaker;

Step 1102,1103 and 1104 sequencing can flexible combination, if first discharge the current user's of saying dedicated bearer, then set up dedicated bearer for seizing UE, are also the concrete embodiments of one of the present invention; Seize if when UE sets up dedicated bearer failure and can discharge whole group calling, also can from talking right queuing queue, get the UE ranking the first, for it is set up dedicated bearer and authorizes right of speech.

Step 1105, cluster core net are carried to seizing user and are sent right of speech authorization messages by dedicated signaling, and prompting is seized user's speech privilege and seized successfully, and seizing user becomes the new user that says.Cluster core net sends right of speech prompting message to all users of listening in group in the carrying of new business, the current information of saying user of user in group of notifications.

Below in conjunction with accompanying drawing, embodiments of the invention five are described.

The flow process of a kind of cluster right of speech method for pre-emptively that as shown in figure 12, the embodiment of the present invention provides comprises:

Step 1201, cluster listen user to initiate RRC connection request, and seize to the cluster core network requests business right of speech different from current business by NAS message;

After step 1202, cluster core net receive that right of speech is seized request message, user's service priority is seized in judgement, if it is higher than the current user's of saying service priority to seize user's service priority, if it is high to seize the current user of saying of user's priority ratio, initiate UE context Establishing process to seizing user, reshuffle user's RRC link, set up dedicated bearer for seizing user;

The UE that simultaneously initiates to seize for other ranks according to service priority height, selects the UE that comes head of the queue to carry out right of speech mandate after the current UE release speech right of seizing; Or the business number that allows multiple business simultaneously and deposit in the configurable group calling of cluster core net, for multiple users of seizing carry out right of speech mandate, multiple business is seized successfully simultaneously; Or only set up dedicated bearer for the highest UE of priority, initiate for other UE seizing simultaneously, cluster core net is given and is seized UE and return to right of speech and seize refusal by NAS message;

Step 1203, cluster core net, for the interior all users that listen of group, comprise that the current user of saying sets up the dedicated bearer of seizing new business, for transmitting media and the signaling flow of new business.If there are multiple business to seize simultaneously, listening with setting up separately per family dedicated bearer for each business;

The sequencing of step 1202 and step 1203 can flexible combination, if the first carrying for listening user to set up new business, then set up dedicated bearer for seizing UE, be also the concrete embodiment of one of the present invention;

Step 1204, cluster core net are carried to seizing user and are sent right of speech authorization messages by dedicated signaling, and prompting is seized user's speech privilege and seized successfully, and seizing user becomes the user that says of new business.Cluster core net sends right of speech prompting message to all users of listening in group in the carrying of new business, and the current information of saying user of user in group of notifications have multidigit right of speech user, but every kind of business only has a right of speech user in group simultaneously.

Embodiments of the invention provide a kind of cluster right of speech method for pre-emptively, device and system, cluster listens user to initiate RRC connection process of establishing, send right of speech to cluster core net and seize request message, right of speech is seized in application, cluster core net receives cluster and listens the right of speech that user sends to seize request message, described cluster core net judges that described cluster listens user's priority, the priority of listening user at described cluster is during higher than the current user of saying, listen user to send right of speech authorization messages to described cluster, described cluster listens user to receive the right of speech authorization messages that described cluster core net sends, realize business and the user of high priority in organizing and carried out the demand that right of speech is seized on the trunked communication system of broadband, solve the problem of trunked communication system diversification, make the application of cluster communication system more flexible, diversification.
