Description
Technical Field
The embodiment of the disclosure relates to the technical field of mobile communication, in particular to a group management method, a device, a communication device and a storage medium of a cluster system.
Background
The dynamic reorganization function in the broadband cluster system refers to that a dispatching Desk (DC) creates, modifies and deletes groups in the system, and adds and deletes members and modifies group attributes to a certain group. The dynamic reorganization should operate the terminal through the air interface, and the terminal receiving the instruction should immediately reply to the confirmation. After receiving the reply from the terminal, the network side shall report the result to the dispatching desk.
In the private network broadband cluster system standard (B-trunk) protocol, after a certain dispatching desk initiates dynamic reorganization operation to a certain group in the broadband cluster system (newly added group/modified group/deleted group), firstly G-TCF (Group Trunking Control Function, group control cluster control function) and eHSS (Enhanced Home Subscriber Server ) store the successful result of dynamic reorganization operation (recorded as dynamic reorganization configuration information), defaulting all terminals to be dynamic reorganization successful, and then G-TCF notifies the terminals to perform dynamic reorganization through group information update. In the case where some terminals fail to respond, the hss and the G-TCF have already stored the dynamic reorganization operation results of all terminals as successful, but the terminal that fails to respond does not actually succeed in dynamic reorganization. Finally, the actual dynamic reorganization result of the terminal is notified to the H-TCF and the dispatching desk to which the dispatching desk belongs, so that the dynamic reorganization result stored by the eHSS and the G-TCF is asynchronous with the dispatching desk and the terminal side. For example: when the dynamic reorganization fails due to the fullness of the terminal belonging group, the failed terminal always exists in the group information of the eHSS and the G-TCF, the failed terminal does not actually join the group, and the intra-group call initiated by other terminals cannot be received by the terminal. In view of this problem, a method is needed to solve the problem of data asynchronization of dynamic reorganization.

The broadband cluster system consists of a broadband cluster terminal (UE), a broadband cluster base station, a broadband cluster core network and a dispatching Desk (DC). The broadband cluster terminal accesses the broadband cluster base station through the Uu-T air interface to realize broadband data and cluster service. The broadband cluster base station is connected with a broadband cluster core network through an S1 interface, and the broadband cluster core network is a network for providing broadband cluster service. The dispatching desk is connected to the broadband cluster core network in a wired or wireless mode, and can initiate a special terminal of cluster dispatching service, wherein the service authority is higher than that of a common terminal.

The cluster core network G-TCF and the eHSS reject the failed terminal out of the group, so that the problem that the members of the group between the dispatching desk and the cluster core network are not synchronous when the dynamic reorganization of the prior art and the increase of the terminal fail is avoided.
Fig. 1 is a flow chart of a group management method of a cluster system according to an embodiment of the present disclosure, where the group management method of the cluster system is applied to a home cluster control function H-TCF (Home Trunking Control Function) of a dispatching desk in the cluster system. As shown in fig. 1, after the dispatcher initiates the dynamic reorganization of the group, the group management method of the cluster system may include, but is not limited to, the following steps 101 and 102:
in step 101, after the H-TCF acquires the dynamic reorganization result, the updated group member information result is determined based on the dynamic reorganization result, and the dynamic reorganization result is sent to the dispatcher station.
In this embodiment, the dynamic reorganization result obtained by the H-TCF is specifically: the H-TCF receives a dynamic reorganization result sent by a home cluster control function of a terminal in the cluster system, wherein the dynamic reorganization result is a dynamic reorganization result generated by the home cluster control function of the terminal based on a group information update result, and the group information update result is a group information update result sent by a mobility management entity MME (Mobility Management Entity) in the cluster system to the home cluster control function of the terminal.

In some embodiments, the elements included in the group member information update result are shown in the following table:
in step 102, after receiving the acknowledgement receipt message sent by the dispatcher station, the H-TCF sends a group member information update result to the group control cluster control function G-TCF in the cluster system, where the group member information update result is used by the G-TCF to initiate a group member update request to the enhanced home subscriber server hss in the cluster system.
In this embodiment, the acknowledgement receiving message sent by the dispatcher is, for example, a successful status code (200 OK). After the H-TCF receives the 200OK sent by the dispatching desk, the H-TCF sends the updated result of the group member information to the G-TCF. The G-TCF initiates a group member update request to an enhanced home subscriber server eHSS (enhanced Home Subscriber Server) in the clustered system.
