Problems solved by technology

[0006] The technical problem solved by the present invention is to provide a method for triggering group information synchronization on the network side in real time in the trunking communication system. When the group information is changed on the network side, the trigger will actively initiate a real-time group information update operation to the terminal side. In this way, the corresponding group information can be obtained in real time on the terminal, which overcomes the problem that the group information on the network side and the terminal side cannot be synchronized in real time in the prior art

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The basic network architecture of the digital trunking communication system is as follows: figure 1 As shown, it includes logical function modules such as trunking terminal, base station subsystem BSS, switching subsystem MSS, and trunking dispatching subsystem DSS.

[0026] The trunking terminal is connected with the base station subsystem (BSS) through the air interface, and provides users with various services of the trunking system, and also provides users with traditional ordinary telephone services, short message services and data services.

[0027] The base station subsystem BSS (BASE STATION SUBSYTEM) mainly completes the wireless access functions of various trunking services, data services and ordinary telephone services. The BSS is composed of a base transceiver station BTS (Base Transceiver System), a base station controller BSC (Base Station Contr...

Abstract

This invention relates to a method for triggering cluster information synchronization by network side in the cluster communication system, first of all, the customer end of a schedule station manages clusters to transmit said user information and cluster information to a cluster schedule server, which asks for a call ID to a cluster authentication server, and the server sends a call ID to it and transmits call to the terminal by the call ID, then the schedule server asks for clusters and user information needing to be updated to the authentication server, which sends said message to the cluster schedule server to update it to the terminal, finally, the schedule server judges if it is the cluster member adition operation and processes it relatively.

Description

technical field [0001] The invention relates to the field of cluster communication, in particular to a method for triggering group information synchronization in real time at the network side in a cluster communication system. Background technique [0002] The trunking communication system was born in the 1970s. The earliest trunking communication system was an analog system. The digital trunking technology emerged around the world in the mid-1990s, and a digital trunking network appeared in China in the late 1990s. Digital trunking communication technology has the advantages of high communication channel utilization rate and large system capacity, so it has been widely used. [0003] The two most important services of trunking technology are dispatching and group calling. The dispatching function of the trunking service refers to initiating calls to a certain number of terminals at the same time, allowing these terminals to participate in a call at the same time; the group...
