Group calling authentication method for cluster system

Abstract

The present invention relates to a method for group call authentication in a trunking system, comprising: a scheduling server receives a group call request; the scheduling server takes out the attributes of the calling end and the called group, processes them into a group call authentication request message, and sends it to Authentication server; the authentication server reads the group call authentication request message, and judges whether the calling terminal and the called group are legal; the authentication server queries the calling terminal information and the called group according to the group call authentication request message. information, process it into group call authentication response information and send it to the dispatching server; the dispatching server reads the group call authentication response information, and judges whether the group is in a calling state, and if so, adds the caller to the group call, and the authentication ends ; If not, the scheduling server initiates paging to all members in the group according to the called group information, and the scheduling server interacts with the authentication server to obtain the information of each member in the group. The invention can effectively increase the speed of group call initiation, and speed up the speed of users joining calls after a delay.

Description

technical field [0001] The invention relates to a group call authentication method, in particular to a group call authentication method in a digital trunking communication system. Background technique [0002] The trunking communication system was born in the 1970s. The earliest trunking communication 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. One of the most important features of trunking technology is the ability to make group calls. The group call function of the trunking service refers to calling a group number on a communication terminal or a dispatching console, and all terminals in the group can be called into one call at the same time, so as to achieve the effect of multiple people talking at the same time. Obviously, when a group call is initiated, the speed at which users in the group join the group call is a very critical and important factor ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an efficient group call authentication method in the trunking communication system, so as to solve the slow speed of group call initiation and the late joining of users in the existing trunking system. Problem with slow calls
