Description
Technical field
The present invention relates to the trunking communicating technology field, particularly a kind of implementation method of terminating group call.
Background technology
Trunking communication (Trunk Communication) claims cluster wireless communication (Trunked Radio) again, be that professional user with the various classification sparse capacity of some puts together, utilize the wireless channel of same bus, carry out the multipurpose based on command scheduling, high-effect private radio communication.For the private radio communication that talkback system disperses to move like this, the level of resources utilization is not high, trunking communication has the advantages that dynamic channel allocation, channel shared by multiple users resource etc. make full use of limited radio channel resource, makes the member who participates in trunking communication can share abundant specific function and business.
Voice group call service (Voice Group Call Service, VGCS) and Voice Broadcast Service (VoiceBroadcast Service VBS) belongs to cluster communication service, or is referred to as group-calling service.The member who comprises two kinds of identity in the VGCS business, i.e. dispatcher and service-user.The dispatcher can be that the fixed network user also can be the mobile subscriber, by being the Speech Communication of the dedicated channel participation group calling of its foundation, existing GSM 800M digital cluster system (GSM Trunk 800M, GT800) in the standard, the VGCS business can not have dispatcher or maximum five dispatchers; Service-user has referred to subscribe the mobile subscriber of VGCS business, and quantity is not limit, and participates in the Speech Communication of group calling by the group-calling channel in the group call region.VBS has the business function similar with VGCS, and main difference is in the VBS business, have only the promoter of broadcasting that the right of speech is arranged, and promoter's identity can only be the dispatcher; Other members, the dispatcher who comprises domestic consumer and non-promoter does not have the right of speech.Particularly point out as nothing, the group calling of this specification the following stated is an example with the VGCS business all, and the correlation circumstance of VBS can be according to the simple analogy of the explanation of VGCS business is drawn.
The VGCS business only permits a service-user at any time and maximum five dispatchers talk simultaneously, and the service-user or the dispatcher of speech are called the talker, and other are not in the service-user of saying speech phase and are called the group calling hearer.The group calling hearer can be by pressing PoC (the Push ToTalk on the portable terminal, PTT) key, realize robbing the operation of reverse link traffic channel according to the principle of " First come first served ", successfully can obtain speaking right participation speech if rob reverse link traffic channel, other group callings hearer has only the operation that just can continue to rob reverse link traffic channel when reverse link traffic channel is idle.The dispatcher has the designated lane of oneself, can participate in speech at any time.
(Group ID G-ID) determines with group call region is unique a specific group calling communication by the group calling sign.G-ID and group call region are called group call reference altogether, i.e. the unique definite group calling communication of group call reference.G-ID identifies the function of this group, and promptly the member by which identity participates in; A mobile subscriber a plurality of G-ID that can contract simultaneously, and different priority is set to them.Group call region is meant the scope that group calling communication covers, and is base unit with the wireless area, can be made up of one or more sub-districts that belongs to identical mobile switching centre (MSC) or different MS C, and the sub-district of forming group call region is called group call cell.When group-calling service carried out, each group call cell had a group calling passage, and the talker is operated in the group emission mode, by reverse link traffic channel transmission dialog context wherein; All group calling hearers are operated in group receive mode, receive dialog context by downlink traffic channel.(Notification Channel NCH) goes up broadcasting to the notification message of relevant group calling at notification channel.
Can trigger the process ends of calling talk in the prior art by following arbitrary condition: service-user is initiated terminating group; Dispatching desk is initiated terminating group; The non-Active Timer of group calling is overtime.Here we only consider that service-user initiates the situation of terminating group, in general, have only the service-user of initiating group calling can terminating group, and other service-users are had no right terminating group.To account for the right that could obtain speech after the up channel the same robbing with service-user, service-user also need rob account for up channel after, could be to the request of network example initiation terminating group business, thus the realization terminating group call.In the prior art, the service-user of initiating group calling can comprise the steps: by Signalling exchange flow process terminating group call as shown in Figure 1
Step 101: when the up channel of group calling is idle, the base station sub-system of network side (Base StationSystem, BSS) issue (UPLINK FREE) message of up free time at the group calling down channel, comprise that all service-users of this group-calling service of participation of the service-user (being designated hereinafter simply as user A) of initiating group calling and other service-users all can be received up idle message;
Step 102: user A sends up access (UPLINK ACCESS) message to BSS, comprises sign and the group call reference of user A in this message;
After step 103:BSS receives up access message, generate upstream request (UPLINK REQUEST) and the upstream request that is generated is sent to MSC according to wherein service-user sign and group call reference;
After step 104:MSC receives upstream request, sign and the group call reference of user A are verified that checking is returned upstream request by the back to BSS and responded (UPLINK REQ ACK);
After step 105～106:BSS receives that upstream request is responded, send permission up access (UPLINK GRANT) message to user A, and return upstream request to MSC and confirm (UPLINK REQCONF) message;
Step 107:BSS sends up busy (UPLINK BUSY) message at group calling down channel all service-users in group calling;
Step 108: user A sends Asynchronous Balanced Mode (Set AsynchronousBalanced Mode, request SABM) of setting up to BSS;
After step 109:BSS sets up Asynchronous Balanced Mode, return the response message of finishing SABM to user A;
Step 110: user A by the uplink group cal channel to MSC send ending request (TERMINATIONAL REQUEST, TR);
After step 111:MSC receives ending request, the sign of user A is verified judge whether it has the right to finish this group calling, checking is returned end (TERMINATION) message by rear line A;
Step 112:MSC to the BSS of relevant this group calling send clear command (CLEARCOMMAND);
Step 113: each BSS related with this group calling discharges (CHANNEL RELEASE) by descending group-calling channel transmitting channel, and message is to all service-users, and multicall channel releasing, finishes this group calling.
In the above-mentioned flow process, step 101～109 take the process of up channel for user A, and step 110～113 are only the process that user A initiates terminating group.From above flow process as can be seen, must be when the group call uplink channel not be taken by other service-users, when promptly up channel was in idle condition, user A could initiate the flow process of terminating group, and when up channel was taken by other service-users, user A can't terminating group.
If group Call system is supported the up channel preemption function, it is the shared up channel of talker that the group-calling service user of high priority can seize low priority, the service-user of desiring terminating group so also can take up channel by the uplink rob function, and then according to the step 110 among Fig. 1 to 113 terminating groups, but following precondition arranged:
1, system must support the uplink rob function;
2, the speech priority of the service-user of desire terminating group is than current talker's height.
If do not satisfy any one of above-mentioned precondition, then service-user still can not be under the occupied situation of up channel terminating group.
Summary of the invention
In view of this, the objective of the invention is to, propose a kind of implementation method of terminating group call, can under the occupied situation of up channel, initiate terminating group by service-user.This method comprises the steps:
A, when the group call uplink channel is taken by other service-users, first service-user is initiated immediately assignment process and is obtained new channel to network side;
B, first service-user send the terminating group request by described new channel to network side;
C, network side judge whether terminating group after receiving the terminating group request, if then initiate the process of terminating group.
The described initiation of steps A assignment process immediately comprises:
A1, first service-user leave group receive mode, to base station sub-system BSS channel request;
After A2, BSS receive channel request, be that first service-user distributes a channel, send the immediate assignment message of the descriptor that comprises the channel that is distributed to first service-user;
A3, first service-user send the Asynchronous Balanced Mode SABM request of setting up according to the immediate assignment message of being received to described BSS;
After A4, BSS set up Asynchronous Balanced Mode, return the response message of finishing SABM to first service-user.
Preferably, steps A 1 described channel request is: by Random Access Channel RACH channel request.
The request of the described transmission terminating group of step B is: transmission comprises the mobile terminal identification of first service-user and the ending request TR of group call reference;
Then step C is described is judged as: the mobile terminal identification among the TR is authenticated, judge whether this portable terminal has the right to finish the pairing group calling of described group call reference.
The process of the described terminating group of step C comprises:
C11, MSC send end by described new channel to first service-user, and BSS transmitting channel release message discharges this newly assigned channel, and first service-user is got back to idle condition;
C12, MSC send clear command to all BSS related with this group calling;
After C13, BSS receive clear command, issue channel release message, and finish the release of group-calling channel at each group calling down channel.
The described judged result of step C is not, then further comprises:
C21, MSC send to first service-user by described new channel and finish refuse information;
The BSS that C22, first service-user belong to sends the channel release message that comprises the group-calling channel descriptor by described new channel to first service-user;
C23, first service-user are got back on the group-calling channel according to the channel descriptor in the channel release message of being received and are continued with group receive mode work.
The new channel that described first service-user obtains is bypass Dedicated Control Channel SDCCH.
Described first service-user perhaps is the service-user that has the authority of terminating group for initiating the service-user of group calling.
Described group calling is group calling or the group calling of Voice Broadcast Service VBS or the group calling of Voice Broadcast Service VBS of voice group call service VGCS.
As can be seen from the above technical solutions, first service-user is by the other channel of channel assignment process application, and first service-user sends ending request by the channel of new application to network side, and then realizes terminating group; So just realized under the occupied situation of uplink group cal channel, service-user needn't be waited for the uplink group cal channel idle and directly initiate terminating group, thereby can make unnecessary group-calling service in time obtain discharging, save system resource and saved the service-user use required time of group calling.And the inventive method need not system and supports the uplink rob function, and the priority of the service-user of terminating group is not required the application of convenient this method.
