Description of drawings
Fig. 1 initiates to carry out the process that group call region is set for arbitrary user in the cluster user group.
Fig. 2 initiates to carry out the process that group call region is set for the colony dispatching platform.
Embodiment
Existing group call region is set when the cluster user group is opened an account and is determined, owing to can not dynamically revise, has limited the moving range of cluster user group.The present invention adjusts by cluster user group side reporting group call zone and asks to network side, and network side is redistributed group call region, and returns the group call region allocation result to cluster user group side, thereby has realized the dynamic setting of group call region.Be elaborated below in conjunction with accompanying drawing.
The calling of group service belongs to collective behavior, requires the cluster user in all groups all, just can effectively answer in advance in the group call region range of receiving of agreement in collective.Therefore, the zone of action of every group of cluster user generally all can be predicted.The scope of activities predictability of cluster user group becomes the true basis of setting group call region.
Referring to shown in Figure 1, Fig. 1 initiates to carry out the process that group call region is set for arbitrary user in the cluster user group.Detailed process is as follows:
When arbitrary user in the cluster user group has the group call region of adjustment demand, this user sends the group call region adjustment request that carries cluster user group group number in modes such as voice or short messages to the colony dispatching platform of this cluster user group, and the colony dispatching platform allows request carry the sector auxiliary information of base station distribution topological diagram correspondence and to be forwarded to cluster service center.Described base station distribution topological diagram and corresponding sector auxiliary information thereof are stored on the terminal of network side network management system usually, for wired colony dispatching platform, because wired colony dispatching platform can link to each other with the terminal of network management system, therefore can directly obtain the sector auxiliary information of base station distribution topological diagram correspondence; For the wireless colony dispatching desk, can the sector auxiliary information of base station distribution topological diagram correspondence be issued to wireless colony dispatching desk and storage by network side.
Then, because the variation that the variation of group call region may bring Resource Allocation in Networks, therefore whether cluster service center allows this request according to current resource allocation conditions and resource allocation algorithm decision, if allow, be the new group call region of cluster set of dispense then according to the demand of the group call region of dynamically adjusting and in conjunction with the sector auxiliary information of base station distribution topological diagram correspondence, revise list of sectors, and being kept at cluster service center, cluster service center is notified the result of cluster user group group call region adjustment in modes such as voice or short messages by the colony dispatching platform then; If do not allow this request, then this user resends group call region adjustment request, and list of sectors remains unchanged.
Above-mentioned group call region adjustment request is by arbitrary reporting of user in the cluster user group, if the user of cluster user group sends group call region adjustment request, then can bring bigger impact to Internet resources.Therefore, the present invention also can only for example adjust request in colony dispatching platform reporting group call zone by the middle-and-high-ranking other user of cluster user group.Embodiment is referring to shown in Figure 2.
Fig. 2 initiates the process that group call region is set for the colony dispatching platform.When the cluster user group had the group call region of adjustment demand, the colony dispatching platform sent group call region adjustment request in modes such as voice or short messages to cluster service center, and this request carries the sector auxiliary information of cluster user group group number and base station distribution topological diagram correspondence; Because the variation that the variation of group call region may bring Resource Allocation in Networks, therefore whether cluster service center allows this request according to current resource allocation conditions and resource allocation algorithm decision, if allow, be the new group call region of cluster user set of dispense then according to the demand of the group call region of dynamically adjusting and in conjunction with the sector auxiliary information of base station distribution topological diagram correspondence, revise list of sectors, and being kept at cluster service center, cluster service center is notified the result of colony dispatching platform cluster user group group call region adjustment in modes such as voice or short messages then; If do not allow this request, then resend group call region adjustment request, list of sectors remains unchanged.
The cluster user group that certain Changing Pattern is arranged for scope of activities, perhaps in time or the regular strong cluster user group of regional change, can draft out several restructuring plans according to the rule of the variation of group call region, when the group call region of adjustment demand is arranged, restructuring plan and group call region adjustment request are together sent to cluster service center, perhaps restructuring plan is stored in cluster service center in advance, after cluster service center is received group call region adjustment request, automatically the group call region tissue of restructuring plan appointment is become the temporary group calling zone list of cluster group, and define with list of sectors.The mode of this restructuring plan helps dealing with the instrument of disaster or critical event or provisional activity, and it makes trunked communication system can store the reorganization scheme that is used under the great situation, suitably adjusts call mode and zone, increases work efficiency.
The present invention also can combine with location technology for the new group call region of cluster user set of dispense.For example, the navigation system of network side detects cluster user group user or the current sector position of colony dispatching platform, cluster service center is the center with this sector just, with fixing on every side several sectors is radius, perhaps radius to come out by certain algorithm computation, dynamically determine some sectors, distribute different radius size to distribute group call region according to different user classs.
