Abstract
The present invention discloses a method for group users to confirm the initiation of a group call and release the group call, which comprises the steps: a. a group system network side receives group call establishment requests in the same time, wherein the call establishment requests are sent be a plurality of group users in the same group of the same group call zone and carry the priority information of the group users in the group; B. the group system network side determines the group call establishment request of the group user who has the highest priority in the group, and thus, the group user is the initiating group user of the current group call. Because the priorities of the group users in the group are led in by the method in the procedures of group call establishment and group call release, the users with different priorities thoroughly embody the priorities of the users in the group in the procedures of the group call establishment and the group call release, which make the dispatch in the whole group very effective.
Description
Technical field
The present invention relates to the technology that group calling is set up and discharged, particularly determine the cluster user method that group calling is initiated and discharged group calling.
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, and leading the interior user of (NCH) group of notifications by the notice letter of each sub-district has group calling to initiate, 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.
Introduce the cluster in-group priority in group system, realize having cluster user in the cluster group of high priority in the cluster group and seize process that the uplink group cal channel talks 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.
Though the described method of Fig. 2 has been quoted the preemption mechanism of cluster in-group priority notion and corresponding uplink group cal channel.But the preemption mechanism of this uplink group cal channel has only been considered situation about having set up in the group calling of cluster group, promptly set up the priority that back broadcasting takies uplink group cal channel cluster user in group calling, thereby make the cluster user that will initiate preemption mechanism compare the cluster in-group priority of self and the height of the cluster in-group priority of broadcasting, whether decision initiates preemption mechanism.Therefore, the preemption mechanism of this uplink group cal channel is not considered the situation when the group calling of cluster group is set up, promptly the group system network side can't be known the cluster in-group priority that will take uplink group cal channel cluster user when group calling is set up, in-group priority that can't more a plurality of group calling request senders, thus the cluster user that can't realize limit priority in the choice set group is initiated cluster user as current group calling.This may cause the low cluster user of cluster in-group priority to become current group calling initiation cluster user.
Further, the cluster user that discharges this group calling at present can only be initiated cluster user for current group calling, and other high priority cluster users in this cluster group can't discharge this group calling, when this finally caused the interior lower priority cluster user of cluster group to initiate this group calling, the higher priority cluster user also had no right to discharge this group calling in the cluster group.
Summary of the invention
In view of this, main purpose of the present invention is to provide the cluster user method of a kind of definite group calling initiation and release group calling, this method makes the interior high priority cluster user of cluster group can initiate or discharge group calling at the cluster in-group priority of group call establishment process and group calling dispose procedure introducing cluster user.
According to above-mentioned purpose, technical scheme of the present invention is achieved in that
The cluster user method that a kind of definite group calling is initiated, this method comprises:
Request is set up in the group calling that A, group system network side receive that a plurality of cluster users of the same cluster group of identical group call region send at one time carries self cluster in-group priority, and self cluster in-group priority that this group calling request of setting up is carried obtains from cluster user self Subscriber Identity Module;
The cluster in-group priority that the group calling that B, the comparison of group system network side the are received request of setting up is carried is determined to send the group calling of carrying priority in the maximum set group and is set up the cluster user of request, and this cluster user is that cluster user is initiated in current group calling.
Before steps A, this method also comprises: the cluster user in group call region is initiated the group calling request of setting up of this cluster group to the group system network side.
After step B, this method also comprises: the group calling foundation request that other cluster users the cluster user of asking are initiated is set up in the group calling of group system network side refusal priority in carrying maximum set group.Described set up the group calling request for the layer three message.
Described self cluster in-group priority is to write when cluster user is opened an account or be written in the Subscriber Identity Module by air interface by the group system network side; Or when revising or revise the cluster in-group priority by the group system network side by air interface, cluster user is written in the Subscriber Identity Module again.
After step B, this method also comprises: the group system network side is broadcasted in this group call region and is carried the uplink group cal channel busy message that precedence of grouped user in group is initiated in current group calling.
A kind of cluster user method of definite release group calling, the priority of cluster user is initiated in the current group calling of group system network side storing, and this method comprises:
After A, group system network side are received the current group calling request of the release that carries this precedence of grouped user in group of cluster user transmission, judge and send whether the cluster user that discharges current group calling request is that cluster user is initiated in current group calling, if, it is the cluster user that discharges current group calling that the group system network side determines to send the cluster user that discharges current group calling request, discharges current group calling; Otherwise, execution in step B;
This precedence of grouped user in group that B, group system network side carry according to this request, judge whether the priority that sends the cluster user that discharges current group calling request is higher than current group calling and initiates cluster user, if, it is the cluster user that discharges current group calling that the group system network side determines to send the cluster user that discharges current group calling request, discharges current group calling; Otherwise,, finish this processing that begs off from doing.
Described group system network side storing has current group calling to initiate the network identity of cluster user;
The current group calling request of the described release of steps A carries the network identity of the cluster user of this request of transmission; Whether the described judgement of steps A sends the cluster user that discharges current group calling request is that the process that cluster user is initiated in current group calling is: to initiate user's network identity identical with the current group calling of group system network side storing relatively to discharge network identity that current group calling request carries, if, sending the cluster user that discharges current group calling request is that cluster user is initiated in current group calling, otherwise sending the cluster user that discharges current group calling request is not that cluster user is initiated in current group calling.
Cluster user writes self cluster in-group priority or is written in the Subscriber Identity Module by air interface or is written in the Subscriber Identity Module again when cluster user is revised or revised the cluster in-group priority by the group system network side by air interface by the group system network side when cluster user is opened an account; This precedence of grouped user in group that the current group calling request of described release is carried is that cluster user obtains from the Subscriber Identity Module of self.
From such scheme as can be seen, the present invention introduces the cluster in-group priority in group call establishment process, judge that at the group system network side a plurality of initiations set up the cluster in-group priority height of the cluster user of group calling request, finally accept the group calling request of setting up of limit priority cluster user in the cluster group, and refuse the group calling request of setting up of other cluster users.Same, the present invention introduces the cluster in-group priority in the group calling dispose procedure, judge at the group system network side whether the cluster user of initiating the current group calling request of release is that cluster user is initiated in current group calling or the cluster in-group priority is higher than current group calling initiation cluster user, if one of them, then the group system network side discharges current group calling, otherwise, refuse this and discharge current group calling request.Therefore, the present invention is by being incorporated into the priority in the cluster group in group calling foundation and the dispose procedure, make the interior high priority level group user of cluster group can initiate or discharge group calling, thereby make different cluster in-group priority users in group calling foundation and dispose procedure, demonstrate fully cluster in-group priority separately, make that the scheduling in the whole cluster group is more effective.

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 described in more detail with reference to accompanying drawing.
The present invention is provided with different cluster in-group priorities in the cluster group in advance different users.Method to set up is: the cluster in-group priority of schooling group internal user and cluster group are write for ID number in the SIM card of access customer in advance together; Perhaps the dispatcher of cluster group is by the air interface setting or revise the cluster in-group priority of this schooling group internal user, and the cluster in-group priority of cluster user writes in the SIM card of relative users in this cluster group that will be provided with or revise then.
The process that the cluster of introducing priority is set up upright group calling as shown in Figure 3, its concrete steps are:
Cluster user in step 300, the cluster group is pressed press-and-talk (PTT) key, initiate the group calling request of setting up of this cluster group, this request sends to the group system network side by layer 3 (CM SERVICE) message, and this CM SERVICE message is carried this cluster in-group priority of this cluster user;
The CM SERVICE message that step 301, group system network side receive at one time that a plurality of cluster users of the same cluster group of identical group call region ID initiate carries self this cluster in-group priority, this cluster in-group priority that these CM SERVICE message of group system network side comparison are carried determines to carry the initiation cluster user of the CM SERVICE message of the highest cluster in-group priority;
The cluster user that step 302, group system network side make initiation carry the CMSERVICE message of the highest cluster in-group priority takies the uplink group cal channel, refuses to initiate in other this cluster groups the cluster user of CM SERVICE message simultaneously;
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, and this preemption processes is identical with the preemption mechanism process described in the background technology.
When a cluster group will discharge current group calling, the present invention can provide a kind of method, not only make current group calling initiate cluster user and can discharge current group calling, and make the current cluster user that takies in other high this cluster groups of uplink group cal channel cluster user of priority ratio also can discharge current group calling.
Fig. 4 discharges the flow chart of current group-calling process for the present invention, and its concrete steps are:
When step 400, cluster user are initiated the release group calling, send termination (Terminate) message request to the group system network side and discharge current group calling, this message is carried the cluster in-group priority of cluster user;
After step 401, 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 402; Otherwise, execution in step 403;
Because when sending Terminate message, also 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;
The present invention introduces precedence of grouped user in group in the process that the group calling of cluster group is set up, promptly the group system network side can be known the cluster in-group priority that will take uplink group cal channel cluster user when group calling is set up, thereby relatively will take the cluster in-group priority height of uplink group cal channel cluster user in the end side of group system, the group calling request of setting up that the highest cluster user of cluster in-group priority is initiated is accepted in final decision.
Further, the present invention introduces precedence of grouped user in group in the cluster group discharges the process of current group calling, makes other high-priority users in this cluster group can discharge this group calling.
Therefore, the invention enables the interior high priority cluster user of cluster group in group calling foundation and group calling dispose procedure, to have bigger administration authority, improved the dispatching of group system communication network.
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.
