Dynamic group management method for digital trunking communication system

Abstract

The disclosed method for managing dynamic groups in digital cluster system includes following steps: (1) appointing one or more members as administrators of the groups in user database of the cluster, and assigning authorization for managing groups to administrators; (2) through terminal, administrators send management request of groups to the cluster dispatch server (CDS), as well as appoint number of group going to take operation and number of the group member; (3) after determining the legal message, CDS forwards the management request to cluster home register (CHR); after successful authorization, CHR returns response of successful group management back to CDS; (4) sending the response of successful group management to terminal of administrators of the groups, CDS carries out dynamic groups management for relevant groups. Features are: simple implementation, easy of operation, high efficiency and real time.

Description

A Dynamic Group Management Method for Digital Trunking System technical field The invention relates to a digital trunking communication system, and introduces a dynamic group management method of the trunking system. Background technique The trunking communication system is an advanced mobile dispatching system, which represents the development direction of a dedicated mobile communication network, one of the communication systems. The trunking communication system has the function of sharing available channels for all users of the system and automatically selecting channels. It is a multi-purpose and high-efficiency wireless dispatching communication system for sharing resources, sharing costs, and sharing channel equipment and services. The basic network frame of the digital trunking communication system is shown in Figure 1, including the trunking terminal 1, the base station subsystem BSS2, the switching subsystem 3 and the trunking dispatching subsystem 4, wherein: ...

AI Technical Summary

Problems solved by technology

In some group call situations, unlike the trunking system in Figure 1, there is no special database system like the trunking home register 42, and the group information is stored on the terminal

Although the group management of the terminal has been realized, because the group information is not managed in a centralized manner, the administrator's scheduling ability is weak, the security is poor, and the supported functions are relatively simple, so it is not suitable for professional cluster occasions

In the case of a background database, the group management is generally performed by the database administrator, and the group members are added or removed to modify the related attributes of the group members. This method requires the participation of the database administrator, which is slow, inefficient, and poor in real-time

In some urgent occasions, it may be necessary to manage group members in real time, such as adding some temporary important users to the group, making secret calls, deleting some group members in real time when there are group members making trouble, and prohibiting group members Speaking, allowing group members to speak, adjusting the attributes of group members, etc., the background database management method is definitely not meeting the needs
