Description
Technical field
The present invention relates in the group system treatment technology, particularly a kind of method of definite precedence of grouped user in group to precedence of grouped user in group.
Background technology
Along with development of wireless communication devices, wireless trunking communication system has appearred, be called for short group system.Group system is a kind of less expensive of growing up in recent years, command dispatching and communication system more flexibly, be widely used in units such as government bodies, energy traffic, airport harbour, industrial and mining enterprises, fire-fighting police, water conservancy and military affairs, to satisfy the needs of constituent parts intercommunication.
In the present group system, each group comprises a group id (ID) and group call region, and wherein group call region is defined as the gang sub-district.But these information all are some when opening an account in attaching position register (HLR) and Subscriber Identity Module (SIM) the card fix information of storage, and be unrealized to group calling user's mobile management.
Fig. 1 is group system core network architecture figure, in the drawings: have user profile among the HLR, comprise this user's international mobile subscriber identity (IMSI), affiliated group ID tabulation; Gateway mobile switch (GMSC) links to each other with external network, and GMSC also links to each other with anchor mobile switch (Anchor MSC); Anchor MSC is in charge of and safeguards a voice group call business (VGCS); Relay MSC, when group call region jumped a plurality of MSC, all MSC except that Anchor MSC were the tree-shaped relation of one-to-many between Anchor MSC and the relay MSC; Visited Location Registor (VLR) has user's IMSI, the ID tabulation of the affiliated group of this user, and when the user roamed, these information copied from HLR and come; Group ID and group call region have been comprised in the Group Call Register (GCR), group call region lumps together with group ID and is called group call reference, wherein with among the continuous GCR of Anchor MSC comprised the dispatcher tabulation relevant with this group call reference, relay MSC tabulation, the directly actuated cell list of Anchor MSC, the GCR that links to each other with relay MSC has then comprised the Anchor MSC address relevant with this group call reference, the cell list that this relay MSC is controlled.
Receive that Anchor MSC inquired about this group attribute to the GCR that is connected when request was initiated in group calling, thereby obtain the cell list under dispatcher's tabulation, relay MSC tabulation and this MSC control; And then call scheduling person, group-calling channel is set up in calling relay MSC and the sub-district under relay MSC control, has group calling to initiate by user in notification channel (NCH) group of notifications of each sub-district, and indicates its group-calling channel so that the interior user of group monitors.
After relay MSC is received the group calling request of Anchor MSC,, in these sub-districts, set up group-calling channel, have group calling to initiate by user in the NCH group of notifications, and indicate its group-calling channel so that the user monitors in the group to the GCR inquiry cell list that is connected.
It is other that cluster user in the common group system in each cluster group all has identical cluster in-group priority, do not have the difference of authority between them, can ask the uplink group cal channel to carry out voice call.If nobody's speech, then uplink group cal channel idle on a time period.Taking the right that cluster user that the uplink group cal channel carries out voice call can also discharge current group calling at any time, but other cluster user haves no right to discharge this group calling.
In same group call region, when a plurality of cluster users initiated simultaneously mutually that request is set up in the group calling of ID on the same group, the group system network side was only accepted the request that one of them group calling is set up, and refuses other group callings user's foundation request.
In some dedicated communications network, for example public security or fire-fighting etc., because the post division of labor is different separately, different cluster user authorities are different usually in the cluster group.As: in the special-purpose group system of public security, than policeconstable's cluster in-group priority height, when promptly the policeconstable talked, the police station can interrupt it police station usually, police station's speech, and the policeman becomes the hearer.Therefore introduced the notion of cluster in-group priority, made high cluster in-group priority cluster user needn't wait until that the low priority cluster user has been said and just have an opportunity to talk.
Below just seize the uplink group cal channel with the cluster user of realizing having high priority in the cluster group process be example, cluster user application to its cluster in-group priority in group system is described, as shown in Figure 2, its concrete steps are:
Step 200, different cluster in-group priorities is set to the cluster user in the cluster group;
The cluster in-group priority of cluster user can write for ID number in cluster user identification module (SIM) card in advance together with the cluster group in the cluster group, and the dispatcher of cluster group also can or revise the cluster in-group priority of cluster user in this cluster group by the air interface setting;
The cluster user of the current speech in step 202, the cluster group is by its cluster in-group priority of talker's indication (TalkerIndication) information reporting;
After step 203, group system network side receive the Talker Indication message of this cluster user transmission, in busy (UPLINK BUSY) message of up channel, issue the cluster in-group priority of this cluster user, other cluster users in the cluster group are monitored descending group-calling channel, promptly obedient user;
When the obedient user in step 204, the cluster group need talk, cluster in-group priority of self and the priority in the UPLINK BUSY message are compared, whether the cluster in-group priority of judging self is higher than the priority in the UPLINK BUSY message, if, execution in step 205; Otherwise, execution in step 208;
Step 205, this obedient user initiate to carry the seizing of uplink group cal channel of self cluster in-group priority to the group system network side;
The purpose that the group system network side is broadcasted this obedient user's cluster in-group priority is that higher cluster in-group priority cluster user can be initiated the preemption processes of uplink group cal channel in this cluster group;
By in the cluster group, introducing the cluster in-group priority, realized that the high cluster user of cluster in-group priority can have more speech chance, make that the traffic control in this cluster group is more orderly, efficient is higher.
Same, cluster in-group priority that also can the application cluster user in cluster group group call establishment process and in the cluster group group calling dispose procedure, be about to precedence of grouped user in group and be carried in the request message that sends to the group system network side, handle accordingly according to the precedence of grouped user in group that request message carries by the group system network side.
But the resulting precedence of grouped user in group of group system network side is that cluster user passes through air-interface information, as Talker Indication message or seize information reporting and give the group system network side.In order between group system network side and cluster user, to realize the mutual of precedence of grouped user in group, just must revise the air-interface information in the group system, even revise the group system group calling and initiate process, this modification to existing cluster user and group system network side is all very big, revise difficulty, limited the development of application cluster user cluster in-group priority in group system.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method of definite precedence of grouped user in group, this method does not need to revise the air-interface information in the group system, just can realize that the user with cluster in-group priority sets up group calling and/or uplink rob and/or discharges group-calling process.
According to above-mentioned purpose, technical scheme of the present invention is achieved in that
A kind of method of definite precedence of grouped user in group is provided with precedence of grouped user in group in the Visited Location Registor under cluster user, and this method also comprises:
After the group system network side is received the current group calling request of release of cluster user transmission, judge whether this cluster user is that cluster user is initiated in current group calling, if the group system network side determines that this cluster user for discharging the cluster user of current group calling, discharges current group calling;
If not, the group system network side is inquired about the Visited Location Registor under this cluster user, obtain the cluster in-group priority of this set in this Visited Location Registor cluster user, whether the cluster in-group priority of judging this cluster user is higher than current group calling initiation cluster user, if, the group system network side determines that this cluster user for discharging the cluster user of current group calling, discharges current group calling; Otherwise,, finish this processing that begs off from doing.
The process that precedence of grouped user in group is set in the Visited Location Registor under cluster user is:
A, the cluster in-group priority of cluster user is stored in the attaching position register;
B, when cluster user moves to Visited Location Registor administration regional, this Visited Location Registor copies this precedence of grouped user in group of home location register stores.
The described precedence of grouped user in group that is stored in attaching position register of step a is stored when cluster user is opened an account or when cluster user is revised.
A kind of method of definite precedence of grouped user in group is provided with precedence of grouped user in group in the Visited Location Registor under cluster user, and this method also comprises::
The group system network side is received the uplink rob request that cluster user sends, and the group system network side is inquired about the Visited Location Registor under this cluster user, obtains the cluster in-group priority of this set in this Visited Location Registor cluster user;
The group system network side judges that the current cluster user that takies the uplink group cal channel is whether than the cluster in-group priority height of the cluster user of initiating the uplink rob request, if not, the group system network side discharges the uplink group cal channel that current cluster user takies, set up the uplink group cal channel for the cluster user of initiating the uplink rob request, otherwise, to this processing that begs off from doing, finish.
From such scheme as can be seen, the present invention stores its cluster in-group priority respectively among SIM card and the HLR when cluster user is opened an account.When being carried out mobile management, cluster user will be kept at that priority copies among the VLR in administration cluster user current roaming zone in the cluster user cluster of HLR.Cluster group priority in the cluster user cluster that advances copies among the VLR in administration cluster user current roaming zone.The cluster group is when carrying out group calling foundation, uplink rob and group calling dispose procedure, the group system network side can be searched the precedence of grouped user in group that VLR obtains to initiate this process, and needn't transmit the message of carrying this precedence of grouped user in group by air interface.Therefore, method provided by the invention does not need to revise the air-interface information in the group system, just can realize that the user with cluster in-group priority sets up group calling and/or uplink rob and/or discharges group-calling process.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, below lift specific embodiment and, the present invention is further described in detail with reference to accompanying drawing.
In order to solve the message of carrying precedence of grouped user in group without the transmission of the air interface between cluster user and the group system network side, promptly do not change existing message, the present invention stores its cluster in-group priority respectively among SIM card and the HLR when cluster user is opened an account or revised.When cluster user was carried out mobile management, promptly cluster user copied among the current VLR that moves to the zone of administration cluster user being kept at priority in the cluster user cluster of HLR when start-up logging or roaming the time move to certain zone.The cluster group is when carrying out group calling foundation, uplink rob and group calling dispose procedure, the group system network side can be searched the precedence of grouped user in group that VLR obtains to initiate this process, and needn't transmit the message of carrying precedence of grouped user in group by air interface.
Even the procedure declaration the present invention who discharges with cluster group group calling foundation, cluster group uplink rob and group calling is respectively transmitted the message of carrying precedence of grouped user in group without the air interface between cluster user and the group system network side below, can realize that also the user with cluster in-group priority sets up group calling, uplink rob and release group calling.
Fig. 3 sets up group-calling process for the present invention realizes the user with cluster in-group priority, and its concrete steps are:
Cluster user in step 300, the cluster group is pressed press-and-talk (PTT) key, initiates the group calling request of setting up of this cluster group, and this request sends to the group system network side by layer 3 (CM SERVICE) message;
After the group calling of this cluster group was set up, other can initiate to seize the process of uplink group cal channel at any time than the current high cluster user of priority that takies uplink group cal channel cluster user, this preemption processes as shown in Figure 4:
Cluster user in step 400, the cluster group compares cluster in-group priority of self and the cluster in-group priority in the UPLINKBUSY message, whether the cluster in-group priority of judging self is higher than the cluster in-group priority in the UPLINK BUSY message, if, execution in step 401; Otherwise, execution in step 406;
Step 401, this cluster user are initiated the request of seizing (UPLINK ACCESS) of uplink group cal channel to the group system network side;
Step 402, the VLR of group system network side under this cluster user is current inquire about its cluster in-group priority, obtain the cluster in-group priority of this cluster user;
Step 403, group system network side are judged the current cluster user that takies the uplink group cal channel whether than the cluster in-group priority height of this cluster user, if not, and execution in step 404, otherwise, execution in step 406;
Step 404, group system network side are accepted this and are seized, and discharge the uplink group cal channel that current cluster user takies, and set up the uplink group cal channel for this cluster user of initiating UPLINK ACCESS, notify this cluster user to talk;
Step 405, group system network side are broadcasted the cluster in-group priority of this cluster user at descending group-calling channel;
Step 406, this cluster user do not allow to initiate UPLINK ACCESS, process ends.
The cluster user that Fig. 5 realizes having the cluster in-group priority for the present invention discharges the flow chart of current group-calling process, and its concrete steps are:
When step 500, cluster user are initiated the release group calling, send termination (Terminate) message request to the group system network side and discharge current group calling;
After step 501, group system network side are received this message, judge whether this message is that the cluster user transmission is initiated in current group calling, if, execution in step 502; Otherwise, execution in step 503;
Because when sending Terminate message, can carry the cluster user network identity in this Terminate message, the group system network side judges whether the cluster user network identity that carries in this Terminate message is identical with current group calling initiation cluster user network identity, if, this message is that the cluster user transmission is initiated in current group calling, otherwise this message is not that the cluster user transmission is initiated in current group calling;
Step 502, group system network side discharge current group calling according to prior art;
Step 503, the VLR of group system network side under this cluster user is current inquire about its cluster in-group priority, obtain the cluster in-group priority of this cluster user;
Step 504, group system network side judge whether the cluster in-group priority of this cluster user is higher than the cluster in-group priority that cluster user is initiated in current group calling, if, execution in step 505; Otherwise, execution in step 506;
Step 505, group system network side discharge current group calling, are about to current group calling and initiate the uplink group cal channel that cluster user takies and discharge;
Step 506, group system network side are refused this Terminate message, and promptly refusal discharges current group calling.
In said process, if the initiation cluster user of cluster group group calling foundation, uplink rob, group calling dispose procedure belongs to the Anchor MSC of group system network side, then send to the relay MSC of group system network side by Anchor MSC priority in the current affiliated VLR query set group of this group system, determine a highest cluster user of cluster in-group priority by the relay MSC of group system network side, carry out the request that the highest cluster user of cluster in-group priority is initiated.
Its cluster in-group priority of inquiry among the VLR of method provided by the invention under the cluster user, thereby need not make the air-interface information of transmitting between cluster user and the group system network side carry precedence of grouped user in group, and only the query script of group system network side has been carried out simple expansion, lower to the upgrade cost of group system network side.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
