Description
Technical field
The present invention relates to trunking communicating technology, refer to a kind of method that realizes that group call merges especially.
Background technology
The group call that defines in the agreement is meant by all user's voice to belonging to certain group in the selection area of authorized user initiation and calls out that described user selected area is called the group call zone, and this calling can make group user realize joint communication.Because the group user in certain group may be distributed in a plurality of sub-districts of trunking communication, so the group call zone can comprise a plurality of sub-districts.All users that belong to same group are discerned by the group identification (ID) of this group, and the ID of group is stored in the portable terminal SIM card of each user's use.Group call comprises group calling (VGCS, Voice Group Call Service) and these two kinds of communication patterns of multicast (VBS, Voice Broadcast Service).The agreement regulation: a plurality of authorized users can be talked simultaneously during group calling; And when carrying out multicast, only allow a group user speech in the same time.
It is that example illustrates that group call of the prior art sets up process that Fig. 1 initiates group call with certain group user to the A of group, and described process specifically comprises:
Step 101, certain group user that belongs to the A of group are sent the group call request to the A of group.
In this step, group user is initiated the group call request to the A of group by dialing " group call prefix+group call reference ".Described group call prefix is used for showing that to network side the call request of this initiation is a group call that it is group calling or multicast that network side also can further be distinguished this group call according to the group call prefix.Described group call shows that with reference to comprising group A sign and group a-quadrant ID group user is that the group party A-subscriber in the group a-quadrant ID institute corresponding region is initiated group call request.
After step 102, mobile switching centre (MSC) received the group call request of this group user, (GCR, group call register) sent the request of group call attribute data to Group Call Register.
The request of described group call attribute data comprises group user sign, group A ID and group a-quadrant ID.Wherein, group user sign is the MSISDN/ISDN number of the group user that makes a call.
After step 103, GCR receive the request of MSC, judge according to the group user sign whether this group user is the authorized user that group A calls out, if then reply the response of group call attribute data, otherwise remove the calling connection that the described group user of step 101 is initiated.The user who supposes to send in this flow process group call request is an authorized user, and then execution in step 104～105.
Described authorized user is meant in group call can take dedicated channel with dispatcher's identity, and the user with full duplex mode participation group call does not need storage sets ID just can initiate group call in this type of user's the terminal SIM card.Have only the authorized user of appointment to initiate group call with dispatcher's identity, all authorized users signs that GCR will organize the A calling all are kept in dispatcher's tabulation of group A.After receiving the request of MSC, GCR searches whether there is the group user sign that makes a call in dispatcher's tabulation, be authorized user if there is this group user of explanation, otherwise this group user is a unauthorized user, so the call failure of its initiation.
Comprise contents such as group a-quadrant information in the described group call attribute data response.Wherein, group a-quadrant information refers to organize all cell ids that comprise in the a-quadrant.GCR finds group a-quadrant information according to the group a-quadrant ID that receives.
Step 104～105, MSC send to base station sub-system (BSS) and call out control connection foundation request, set up one for each base station controller (BSC) in the group a-quadrant and call out control connection.After connecting foundation, BSS answering call control connection is set up and is finished message.
Owing to record the corresponding relation of all cell ids and BSC among the MSC, MSC can determine the BSC of needs foundation calling control connection according to all cell ids that comprise in the group a-quadrant.
Step 106～107, MSC send the foundation of group call passage to BSS and ask, and BSS sets up a group call passage for each sub-district in the group a-quadrant, and message is finished in the foundation of answer group call passage after passage foundation is finished.
Described group call passage is set up and is comprised group A sign and group a-quadrant information in the request.
Notification channel (NCH, NotificationChannel) the group call notification message of last periodic broadcasting group A of step 108, BSS each sub-district in the group a-quadrant.
Described group call notification message comprises the group call passage descriptor that group A identifies and this sub-district is set up.
After the user terminal that contains group A sign in step 109, each sub-district receives the group call notification message of group A, insert according to group call passage descriptor configuration relevant parameter and to intercept the group call passage, participate in the group call communication of group A.
For the user who does not contain group A sign in the user terminal, this terminal can't respond this group call to group A.
Above-mentioned calling procedure all is suitable for group calling and multicast, and the group call prefix that group user can pass through to be dialed informs that network side carries out the group calling or the calling of multicast.Because the described method of the application does not relate to the difference in concrete calling procedure of group calling and multicast, so the two difference is no longer encyclopaedized.
Along with group call is universal day by day in the application of cluster private network and public network, the user also proposes more requirements to the actual application ability of group call, and the user of ID can participate in same group call communication etc. for example to require to have not on the same group when emergency cooperative.Described emergency cooperative is meant: the personnel such as government and fire department adhered to different groups originally separately, so have different group ID, when emergencies such as fire occur needed government and fire department to work in concert, the user of these two groups of temporary needs participated in and realizes the associating voice communication in the same group call.Yet existing cluster calling method can't satisfy the demand, thereby makes the application of group call have limitation.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method that realizes that group call merges, and makes to have not on the same group the user of ID and can participate in same group call and carry out joint communication.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
Among the present invention, network side is set up the merging group for having not ID on the same group but need carry out the associating speech communication in same group call user in advance, and what Fig. 2 showed is the flow chart that network side is set up the merging group in advance, may further comprise the steps:
Step 201, attended operation platform send combination and data setting request to GCR.This request comprises: all son group ID that comprise in the merging group and the authorized user sign that allows to initiate this merging cohort group calls in several.Described authorized user sign can be the MSISDN/ISDN number of authorized user.
Wherein, the attended operation platform is the common equipment that the management maintenance personnel carry out parameter setting and maintenance to network equipments such as MSC, GCR in the prior art.
In the practical application,,, combination that the attended operation platform sends and data setting request pass to GCR so passing by MSC because GCR generally is embedded among the MSC.
Step 202～203, GCR generate according to the request that receives and merge cohort group calls in several attribute data, and reply combination and data setting response to the attended operation platform.
Described merging cohort group calls in several attribute data comprises: merging group ID, belong to this merging group child group ID, comprise dispatcher's tabulation that all authorized users sign is organized in this merging.
Described merging cohort group calls in several attribute data also comprises: the merging group area I D that the merging group area information of this merging group is corresponding with each zone.
Described merging group area information is meant all cell ids that comprise in this merging group zone.For example: the total cell id in whole trunking communication zone is six sub-districts of 1～6.When merging group area I D is 001, this merging group zone is set comprises sub-district 1～4; When merging group area I D is 002, this merging group zone is set comprises sub-district 2～6.GCR can be provided with the merging group zone of merging group area I D correspondence according to actual needs.
Described merging cohort group calls in several attribute data further comprises: each height group area information corresponding with each merging group area I D, and the child group area I D corresponding with each son group zone.Such as: merging group area I D is that 001 merging group zone comprises sub-district 1～4, and child group zone of each the son group that comprises in the merging group can further be set in the zone is organized in merging.Comprise son group A and sub-group B in this merging group, so can comprise sub-district 1～3 such as the child group zone that son group A is set for son group A and son group B establish the stator pack zone from sub-district 1～4, the child group zone of sub-group B comprises sub-district 2～4.
Through combination shown in Figure 2 and data setting operation, GCR is set up a upright merging group that adopts merging group ID identification for the different sons that need carry out the associating voice communication.Described merging group ID is by the network side record, and the group user of wanting to initiate to merge the cohort group calls in several need be known this merging group ID, and the child group user terminal in the merging group needn't be preserved this merging group ID, just can participate in answering the group call of this merging group.
After setting up the merging group, the merging cohort group calls in several that group user is initiated is set up process as shown in Figure 3, specifically may further comprise the steps:
Step 301, group user initiate to merge the cohort group call request.
Step 101 among this step and Fig. 1 is similar, and group user is dialed " group call prefix+merging cohort group calls in several reference " and initiated to merge the cohort group calls in several.This group call can be group calling or multicast.
Described merging cohort group calls in several is with reference to comprising merging group ID and merging group area I D.Omit merging group area I D in the reference of cohort group calls in several if merge, show that this merging group calls in several need contain whole trunking communication zone.Suppose that the merging group area I D that group user is dialed is 001 in this calling.
After step 302, MSC receive the merging cohort group call request of group user, send the request of merging cohort group calls in several attribute data to GCR.
The request of described merging cohort group calls in several attribute data comprises group user sign, merging group ID and merging group area I D.
After step 303, GCR receive the request of MSC, searching the dispatcher tabulates and judges that whether group user is the authorized user that merges the cohort group calls in several, merge the response of cohort group calls in several attribute data if then reply, otherwise the calling that the described group user of dismounting step 301 is initiated connects.Suppose that sending the user who merges the cohort group call request in the present embodiment is authorized user, then continues execution in step 304～305.
In this step, GCR finds the relevant information of this merging cohort group calls in several according to merging group ID and merging group area I D, and carries merging group area information in the response of replying.Described merging group area information is all cell ids that comprise in the merging group zone.If be provided with son group area information among the GCR, then further comprise each son group ID and son group area information in the response of Hui Fuing.Described son group area information is meant all cell ids that belong to this child group in the merging group zone.
Step 304～305, MSC send the control connection foundation request of calling out to BSS, call out control connection for each BSC in the merging group zone sets up one.After connecting foundation, BSS answering call control connection is set up and is finished message.
Owing to record the corresponding relation of all cell ids and BSC among the MSC, MSC can organize the BSC that all cell ids that comprise in the zone are determined needs foundation calling control connection according to merging.
Step 306～307, MSC send the group call passage to BSS and set up request, and BSS is that a group call passage is all set up in all sub-districts in the merging group zone, and reply the foundation of group call passage and finish message after passage foundation is finished.
Step 308, MSC send each height group information to BSS on the group call passage of setting up.Owing to may comprise a plurality of son groups in the merging group, need issue a strip group information for each son group so dot MSC in this step.
Described child group of information comprises son group ID.When preserving son group area information on the GCR, the child group information that issues in this step further comprises son group area information.
Because the merging group area I D of this calling is 001, the child group zone of representing this merging to organize regional neutron group A comprises sub-district 1～3, the child group zone of son group B comprises sub-district 2～4, and then the child group information that sends for group A of MSC is group A sign and corresponding district numbers 1,2 and 3; The child group information that sends for group B is group B sign and corresponding district numbers 2,3 and 4.
Step 309, BSS are according to the child group information group call notification message that each son of periodic broadcasting is organized on the NCH of each sub-district channel.Similarly, also dot BSS in this step and need issue a group call notification message for each son group.
Because the user of existing son group A has son to organize the user of B again in the sub-district 2, BSS needs to be respectively son group A and sub-group B broadcasting group call notification message in sub-district 2.The group A call notification message of being broadcasted for child group A comprises son group A sign and group call passage descriptor, the group B call notification message of being broadcasted for child group B comprises son group B sign and group call passage descriptor, comprises identical group call passage descriptor in two group call notification messages.
After the user terminal that contains sub-group id in step 310, each sub-district receives the group call notification message of son group, the group call passage is intercepted in access according to group call passage descriptor configuration relevant parameter, participates in the group call communication of merging group.For system, the merging group is exactly a normal call service group, so the group call communication of group A or group B is identical in the group call communication of merging group and the prior art, repeats no more herein.
Because the group call passage descriptor that the group call notification message of different son groups comprises is identical, can realize the associating group call communication by intercepting same group call passage so have the user terminal of different sub-group ids.
By the above embodiments as seen, the method that this realization group call of the present invention merges is by being to have not on the same group that the user of ID sets up the merging group at network side, make to have not on the same group that the user of ID can carry out voice communication in same merging cohort group calls in several, convenient, flexible in realization.
