Method for realizing roaming control in clustering system and roaming charging method

Abstract

The invention discloses a method for implementing roaming control and roaming charging in a cluster system, comprising the following steps: a base station receives a location update message sent by a terminal in a local area and transmits it to a dispatch server; the dispatch server according to the location update message The identification of the base station subsystem, find the corresponding dispatching server identification in the dispatching server identification list; the dispatching server sends the received location update message and the inquired dispatching server identification to the authentication server; the authentication server queries The cluster user database obtains the terminal's home scheduling server identifier; compares whether the terminal's home scheduling server identifier is the same as the current authentication server identifier, and determines whether the terminal is within the service area. The method of the invention realizes the functions of effectively controlling the roaming of cluster users and performing roaming charging, and on the basis of effectively reducing the operation cost of the operator, the manageability of the cluster system is highly guaranteed.

Description

technical field [0001] The invention relates to a roaming method of a trunking communication system, in particular to a method for controlling the roaming capability of a terminal and performing roaming charging in a digital trunking communication system. Background technique [0002] The prior art trunking communication system was born in the 1970s. The earliest trunking communication was an analog system. Digital trunking technology emerged around the world in the mid-1990s, and digital trunking networks appeared in China in the late 1990s. The most important feature of trunking technology is the ability to schedule and group calls. The dispatching function of the trunking service refers to calling a certain number of terminals at the same time, allowing these terminals to participate in a call at the same time; the group calling function of the trunking service refers to calling a group number on a communication terminal, and all terminals in the group can be called Inco...
