Description

The method that a kind of group call cell inserts
Technical field
The present invention relates to the trunking communicating technology field, the method that particularly a kind of group call cell inserts.
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.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.
(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.The group-calling service that relates to a plurality of MSC, the management that one of them MSC is responsible for calling out, be called preside over MSC (Anchor MSC, A-MSC), other MSC be called relay MSC (Relay MSC, R-MSC).Storage and the management data relevant with group-calling service among the MSC are comprising the dispatcher's information in dynamic group attribute, the group, group call region information, R-MSC information etc.A-MSC is responsible for setting up all connections, is included in the connection of the designated cell of this MSC, relevant R-MSC and dispatching desk, and finishes the distribution of speech; R-MSC only need set up a link to A-MSC, and R-MSC is responsible for the distribution of the cell downlink speech of its management.
Fig. 1 shows the schematic network structure that realizes the group call cell access process, and for simplicity of exposition, the A-MSC 101 that only draws, a base station controller (BSC) of A-MSC management are that a group call cell below BSC 102 and the BSC 102 is a group call cell 103; If group calling also comprises the group call cell that belongs to other MSC, then also comprise R-MSC 104 in the network at least, and the BSC 105 and the group call cell 106 that belong to R-MSC 104.All not shown in Figure 1 with other network elements that the group call cell access process is irrelevant.
When group calling was set up, for the group call cell 103 that belongs to A-MSC 101, A-MSC 101 will send a VGCS assignment request (VGCS AssignmentRequest) message to the BSC 102 of group call cell 103 correspondences, is designated hereinafter simply as the assignment request; After BSC 102 receives the assignment request, for group call cell 103 distributes group-calling channel, be allocated successfully the back and return VGCS assignment result (VGCSAssignment Result) message to A-MSC 101, the sign that comprises group call cell 103 in this message, the sign of this group calling, and the sign of assignment success, be designated hereinafter simply as the assignment results messages; Distribute failure then to return VGCS Assignment Failure (VGCS Assignment Failure) message to A-MSC 101, comprise the sign of group call cell 103 in this message, the sign of this group calling, and the sign of Assignment Failure are designated hereinafter simply as Assignment Failure message; If A-MSC 101 receives the assignment results messages, then the group call cell with this message correspondence inserts in this group calling, if A-MSC 101 receives Assignment Failure message, then remove the connection of the group call cell 103 corresponding with this message, group call cell 103 can not be linked in this group calling.For the group call cell 106 that belongs to R-MSC 104, then after connecting between A-MSC 101 and the R-MSC 104, send the assignment request by R-MSC 104 to BSC 105, and be that group call cell 106 distributes the group calling passages by BSC 105 according to the assignment request, be allocated successfully the back and return the assignment results messages to R-MSC 104; Distribute failure then to return Assignment Failure message to R-MSC 104, whether R-MSC 104 adds group call cell 106 in this group calling according to assignment results messages of receiving or the decision of Assignment Failure message.
In actual applications, group call region may comprise a lot of group call cells, and in order to guarantee to set up fast group calling, MSC almost sends the assignment request of each group call cell simultaneously, this just probably causes the A interface between MSC and the BSC to occur link congestion abruptly, and then causes the assignment request of part sub-district to be lost; If BSC does not receive the assignment request, then can not return any message to MSC.The treating method that prior art is taked is: when MSC sends the assignment request, start a timer for each bar assignment request, be called timer T1, if up to the overtime response message of not receiving respective cell of timer T1, be assignment results messages or Assignment Failure message, then remove the connection of corresponding group call cell, this sub-district can not be linked in this group calling.
Therefore, the shortcoming of prior art existence is that if lose some of assignment requests when issuing the assignment request to BSC, the pairing group call cell of then losing of assignment request can't be linked in the middle of the group calling.
Summary of the invention
In view of this, the objective of the invention is to, propose the method that a kind of group call cell inserts, can guarantee as far as possible that group call cell is linked in the middle of the group calling.
This method comprises the steps:
A, moving exchanging center MSC send the assignment request first time of specific group call cell to base station controller BSC;
B, MSC judge whether the assignment first time request responding message of receiving that BSC returns, if then this flow process is handled and withdrawed to the handling process that inserts by existing group call cell; Otherwise execution in step C;
C, MSC send the assignment request second time of this group call cell to BSC;
If D, MSC receive the assignment results messages, then this group call cell is inserted this group calling; If receive Assignment Failure message or do not receive response message, then remove the connection of this group call cell.
The described judged result of step B judges further whether the response message of being received is the assignment results messages, if then this group call cell is inserted this group calling and withdraw from this flow process for after being; Otherwise execution in step C.
Steps A further comprises: start timer T2;
Step B is described to judge whether to receive that the request responding of assignment for the first time message is: judge whether that T2 receives the request responding of assignment for the first time message before overtime, if, then for receiving response message, otherwise for confiscating response message.
Described timer T2 duration is 1 second.
Step C further comprises: start timer T1;
The described assignment result/failed message of receiving of step D is: receive assignment result/failed message before timer T1 is overtime;
The described response message of not receiving of step D is: timer T1 is overtime and do not receive response message.
Wherein, described MSC is for presiding over the A-MSC of mobile switching centre or transmitting the R-MSC of mobile switching centre.
Be provided for preserving the assignment situation record to the assignment processing of request result who is received among the BSC, the handling process that described BSC returns assignment request responding message is:
The assignment request of MSC under A1, BSC receive, according to the assignment request retrieval assignment situation record of being received, if in assignment situation record, retrieve to identical assignment processing of request result, execution in step B1 then, otherwise go to step e 1;
Whether step B1:BSC judges in the assignment situation record this assignment processing of request result is success, if, execution in step C1 then; Otherwise go to step D1;
Step C1:BSC generates corresponding assignment results messages according to retrieve result from assignment situation record, and the assignment results messages that is generated is returned affiliated MSC and finished the BSC handling process;
Step D1:BSC is corresponding group call cell assignment group-calling channel according to receiving assignment request, and the assignment success is then returned the assignment results messages to affiliated MSC, and Assignment Failure then returns Assignment Failure message to affiliated MSC, and the BSC handling process is finished in the back that is finished;
Step e 1:BSC is according to receiving assignment request, be corresponding group call cell assignment group-calling channel, the assignment success is then returned the assignment results messages to affiliated MSC, Assignment Failure then returns Assignment Failure message to affiliated MSC, and result is stored in the assignment situation record of this locality, the BSC handling process is finished in the back that is finished.
Be provided for preserving the assignment situation record of being received among the MSC from the assignment result of BSC; Then described MSC receives after assignment results messages or the Assignment Failure message, further comprises:
Search the record whether identical group call cell sign with receiving message, identical group calling sign are arranged in the assignment situation record of having stored, if do not have, then generate the group call cell sign, group calling sign and the assignment result's that comprise the message of receiving an assignment situation record and carry out subsequent step; If have, then further judge the result in the assignment situation record, if the result in the assignment situation record is an Assignment Failure, what received is the assignment results messages, then group call cell sign corresponding district in the assignment results messages is added in this group calling, and it is successful to change the result in the assignment situation record into assignment, and carry out subsequent step; If other situations are then directly carried out subsequent step.
As can be seen from the above technical solutions, after MSC sends the request of assignment for the first time, judge whether to receive the corresponding request responding of assignment for the first time message, if do not receive, then send the request of assignment for the second time, so just can be so that the pairing group call cell of losing of the assignment request first time can also be received assignment request for the second time, and be linked in the middle of this group calling through subsequent treatment; In addition, return the group call cell of Assignment Failure message, also can send the request of assignment for the second time again, make these group call cells also can insert in the middle of this group calling as far as possible for the assignment request first time.Therefore,, can guarantee as far as possible that group call cell is linked in the middle of the group calling, overcome, improve the reliability of system owing to the crowded shortcoming that causes the part group call cell to insert of channel by the inventive method.

Step 208:A-MSC 101 is with group call cell 103 access group callings and process ends.
In the above-mentioned flow process, after sending the assignment request for the first time,, comprise group call cell that does not return response message and the group call cell that returns Assignment Failure message, all will send the request of assignment for the second time the group call cell except returning the assignment results messages; The present invention also can only send the request of assignment for the second time to the group call cell that does not return response message, as long as A-MSC in the step 203 101 is judged that what receive is the assignment failed message, corresponding process operations changes the connection of removing group call cell 103 into, stops timer T2 and withdraw from this flow process getting final product.
Embodiment two: the cut-in method that belongs to the group call cell of R-MSC.
Present embodiment is corresponding to the cut-in method of group call cell among Fig. 1 106.With network configuration shown in Figure 1 is example, and A-MSC 101 as long as set up with R-MSC 104 when beginning to set up group calling is connected, and independently finishes reciprocal process with the BSC 105 of its management by R-MSC then.
The handling process of R-MSC 104 comprises the steps: as shown in Figure 3
After step 301:R-MSC 104 connected with A-MSC 101, the assignment request to BSC 105 sends group call cell 106 started timer T2, and the assignment request of being received is stored in local working area;
Step 302:R-MSC 104 judges whether to receive the response message from BSC 105 before timer T2 is overtime, described response message is assignment results messages or Assignment Failure message, if then execution in step 303, otherwise goes to step 305;
Step 303:R-MSC 104 judges whether the response message of being received is the assignment results messages, if go to step 308, otherwise what receive is the assignment failed message, execution in step 304;
Step 304:R-MSC 104 stops timer T2;
Step 305:R-MSC 104 is sent to the assignment request in the working area BSC 105 and starts timer T1;
Step 306:R-MSC 104 judges whether to receive the assignment results messages before timer T1 is overtime, if then go to step 308, otherwise execution in step 307;
The connection that step 307:R-MSC 104 removes group call cell 106, if receive Assignment Failure message, R-MSC 104 also will stop timer T1, the back process ends is finished;
Step 308:R-MSC 104 is with group call cell 106 access group callings, and the back process ends is finished.
As can be seen, for the group call cell that belongs to R-MSC, the operation that group call cell inserts is given R-MSC fully and is finished from the handling process of above-mentioned present embodiment.
Handling process according to MSC among the invention described above embodiment, BSC may receive twice identical assignment request of content continuously in the very short time interval, and in fact only require BSC to carry out the operation of an assignment group-calling channel, rather than receive that whenever an assignment request just carries out the operation of assignment group-calling channel.Therefore BSC needs to have the assignment request of being received the memory function of short-term, the processing result information of the assignment request correspondence that is about to receive is kept in, described result is and assignment results messages or the relevant information of Assignment Failure message, comprise the group calling sign, the group call cell sign, the result sign, and can assemble out corresponding assignment results messages or Assignment Failure message according to the processing result information of being stored.Described result comprises assignment success and Assignment Failure.When the assignment request of receiving MSC, BSC judges whether identical assignment request to be handled according to the processing result information of storage, if, judge further that then described result is success or failure, if success, then assemble out corresponding assignment results messages, and the assignment results messages of being assembled out is returned MSC according to the processing result information of storage; If the operation of assignment group-calling channel is then carried out in failure, and return assignment results messages or Assignment Failure message to MSC according to the result of operation; If do not receive identical assignment request, then carry out the operation of assignment group-calling channel and to the result of MSC return, and this processing result information is kept in.
Therefore, the present invention program is provided with assignment situation record in BSC, is used to preserve the assignment processing of request result of BSC to being received, as shown in Figure 4, the handling process of BSC comprises the steps:
The assignment request of MSC under step 401:BSC receives, according to the assignment request retrieval assignment situation record of being received, if retrieve this assignment processing of request object information in assignment situation record, then execution in step 402, otherwise go to step 405;
Step 402:BSC judges whether the result corresponding with this assignment request is success in the assignment situation record, if then execution in step 403; Otherwise go to step 404;
Step 403:BSC assembles out corresponding assignment results messages according to the assignment request processing result information that retrieves from assignment situation record, the assignment results messages of being assembled out is returned affiliated MSC and finished this handling process;
Step 404:BSC is corresponding group call cell assignment group-calling channel according to receiving assignment request, and the assignment success is then returned the assignment results messages to affiliated MSC, and Assignment Failure then returns Assignment Failure message to affiliated MSC, and this handling process is finished in the back that is finished;
Step 405:BSC is according to receiving assignment request, be corresponding group call cell assignment group-calling channel, the assignment success is then returned the assignment results messages to affiliated MSC, Assignment Failure then returns Assignment Failure message to affiliated MSC, and assignment request and corresponding assignment results messages or Assignment Failure message be kept in the local assignment situation record, this handling process is finished in the back that is finished.
Content in the described assignment situation record can be set to regularly empty.
BSC adopts above-mentioned handling process, and then MSC can receive two secondary responses to same assignment request from BSC under some abnormal conditions.Therefore, assignment situation record also is set in MSC, be used to preserve assignment processing result information from BSC, when receiving assignment results messages or Assignment Failure message, at first search the record whether identical group call cell sign with receiving message, identical group calling sign are arranged in the assignment situation record of having stored, if do not have, then carry out respective handling, and generate the group call cell sign, group calling sign and the assignment result's that comprise the message of receiving an assignment situation record according to the message of being received; If have, then further judge the result in the assignment situation record, and do following processing according to the result who judges:
First kind of situation: the result in the assignment situation record is the assignment success, and what then no matter receive is assignment results messages or Assignment Failure message, then directly carries out subsequent step;
Second kind of situation: the result in the assignment situation record is an Assignment Failure, what received is the assignment results messages, then group call cell sign corresponding district in the assignment results messages is added in this group calling, and it is successful to change the result in the assignment situation record into assignment, and carry out subsequent step;
The third situation: the result in the assignment situation record is an Assignment Failure, and what received is the assignment failed message, then directly carries out subsequent step.
As can be seen, except second kind of situation, other situations all do not have extra treatment step and directly carry out subsequent step.
More than timer T1 described in two embodiment can be same timer or different timers with timer T2, if same timer, describedly stop timer T2 and start timer T1 being timer T1 resetted and restarting timing.
