With reference to figure 1, this figure is a kind of realization flow figure of call-establishing method in the prior art trunked communication system.
The user dials group number in the prior art, and the signaling of bearing cluster call request sends to trunked communication system (BSS/TMCS).BSS/TMCS initiates paging to the group member who sets in advance, and BSS/TMCS mails to the calling subscriber with the signaling of Bearer Channel assignment then; Behind group member's page response, BSS/TMCS mails to called group member with the signaling of Bearer Channel assignment, finishes call setup, and idiographic flow is as follows:
(s11) cluster user MS1 sends call request message to BSS/TMCS.
(s12) BSS/TMCS inquires the group data of preserving among the TMCS according to the group number in the call request message, learns members such as having preestablished cluster user MS2, MS3......MSn in the group.Initiate paging to cluster user group member MS2, MS3......MSn.Simultaneously cluster user MS1 is carried out channel assignment.
(s13) after cluster user MS2 receives the paging of BSS/TMCS, send page response to BSS/TMCS.
(s14) BSS/TMCS receives the page-response message of cluster user MS2, and cluster user MS2 is carried out channel assignment.
(s15) same, after users such as cluster user MS3......MSn receive the paging of BSS/TMCS, also send page response to BSS/TMCS.
(s16) same, BSS/TMCS receives users' such as cluster user MS3......MSn page-response message, and these users are carried out channel assignment.
There is following shortcoming in above-mentioned prior art:
When cluster user in the working region, then can carry out the colony dispatching activity, but at cluster user not behind the working region, then needn't participate in the schedule activities, but the cluster user outside the prior art working region also can be by system invites in group call, can not satisfy the demand of geographic area restriction in some colony dispatching work, carry out call proceeding for the described user that need not participate in colony dispatching simultaneously and also can cause taking of system resource.
Summary of the invention
The technical problem that the present invention solves provides call-establishing method in a kind of trunked communication system, to avoid the user outside the working region also can be in group call by system invites, satisfy the geographic area restriction demand of colony dispatching work, reduce taking of system resource.
For addressing the above problem, call-establishing method in the trunked communication system of the present invention comprises:
A, receive the setup requests of the group member that makes a call;
B, initiate paging to group member;
Receive the page response of called group member;
Obtain the positional information of this called group member in the described page response;
Judge that according to described positional information this called group member is whether in default call blocking zone, if judged result is for being, then determine this called group member in default call blocking zone, otherwise, determine that this called group member is not in default call blocking zone;
In default call blocking zone, this called group member that then continues to continue is realized call setup as if called group member, if called group member not in default call blocking zone, then refuses to continue this called group member.
Alternatively, described call blocking zone is unit with the sector.
Alternatively, described call blocking zone is the call blocking zone to these all group members of group.
Alternatively, described call blocking zone is the call blocking zone to the designated group member.
Compared with prior art, the present invention has following beneficial effect:
Among the present invention after reception makes a call the setup requests of group member, judge that at first each called group member is whether in default call blocking zone, if called group member is in default call blocking zone, this called group member realization call setup then continues to continue, if called group member is not in default call blocking zone, then refuse to continue this called group member, group user outside the working region that the present invention can avoid dispatching also can be by system invites in group call, satisfy the geographic area restriction demand of colony dispatching work, reduce taking of system resource.
Description of drawings
Fig. 1 is a kind of realization flow figure of call-establishing method in the prior art trunked communication system;
Fig. 2 is a kind of realization flow figure of middle call-establishing method in the trunked communication system of the present invention.
Embodiment
The present invention at first need revise the group data in the trunked communication system, preestablish the call blocking zone, described call blocking zone can be the dispatcher-controlled territory at a group, if exceeding the dispatcher-controlled territory of this group, this group user the service of this group is provided then for this group user, it also can be dispatcher-controlled territory at the designated group member, the dispatcher-controlled territory that surpasses this designated group member provides group service then for this designated group member, dispatcher-controlled territory described in the present invention can the sector or other zones be unit, repeat no more here.
During call setup, after receiving setup requests in the trunked communication system, find group data according to group's group number, with the call blocking zone is that dispatcher-controlled territory at group is an example, trunked communication system will be checked the group member whether in the call blocking zone of group, for those group members in the call blocking zone, and will continue this group member's calling of trunked communication system, otherwise, then continue this group member's calling of refusal.
Need explanation, the user is when Idle state, if the sector at its place changes, may not can initiate registration to trunked communication system, therefore, called group user may occur and leave dispatcher-controlled territory, but situation about also not registering to trunked communication system in new sector; Group user also may occur and enter dispatcher-controlled territory, but situation about also not registering in this sector.But called group user can be with the residing positional information of current reality when trunked communication system sends page response, therefore, trunked communication system can not judge before the paging called whether in the call blocking zone, but judge again after will receiving the page response of called group user by the time, positional information according to called group user in the page-response message, if this called group user not in the call blocking zone, then stops the call proceeding to this called group member.
Specify call-establishing method of the present invention below for example, in the present embodiment hypothesis G1 of group pre-defined cluster user MS1, MS2, three members of MS3, the call blocking zone is sector SECTOR1.MS1 is the calling subscriber, and MS2, MS3 are the called subscriber, and the current physical location of MS2 is at sector SECTOR1, and the current physical location of MS3 is at sector SECTOR2, and concrete call setup flow process is as follows:
(s21) MS1 sends call setup request message, call group G1 to trunked communication system (BSS/TMCS).
(s22) BSS/TMCS finds the group G1 data of preserving among the TMCS, initiates paging to group member MS2, MS3, simultaneously MS1 is carried out channel assignment.
(s23) after MS2 receives the paging of BSS/TMCS, send page response to BSS/TMCS.
(s24) BSS/TMCS receives the page-response message of MS2, obtains the MS3 current position information in page-response message, judges that MS2 in call blocking region S ECTOR1, carries out channel assignment to MS2.
(s25) same, after MS3 receives the paging of BSS/TMCS, also send page response to BSS/TMCS.
(s26) same, BSS/TMCS receives the page-response message of MS3, after TMCS receives page response, obtains the MS3 current position information in page-response message, learns that MS3 is in call blocking region S ECTOR1 SECTOR2 in addition, then discharges MS3.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
