Problems solved by technology

For the group call service, since the number of user terminals in the group under the sector can reach hundreds or even thousands, if the above-mentioned call establishment process is used to establish the call, it will result in a very long time for the establishment of the group call, which is impossible Meet the needs of fast response to cluster communication
[0018] The main feature of trunking communication is that it requires short call connection time and quick call establishment. The traditional cellular mobile communication system can realize the group call function of the trunking system, but it cannot meet the fast access requirements required by the trunking system.

Embodiment Construction

[0044] Group calls and private calls are important service features in the trunking system. A group call means that a single user can talk to all the people in the group at the same time when allowed. Except for the person who is speaking, other users in the group must listen, and once a user in the group presses the PTT button, if the priority of other users is the same as that of the person who is speaking, they cannot intercept and can only wait to speak people to complete the call. A private call is a one-to-one user call. In a group, you can also choose the person you want to talk to and make a call without being heard by other members of the group.

[0045] In the traditional trunking communication system, the group calling user directly calls the group number, and the base station forwards the calling message to the trunking dispatching server, and the trunking dispatching server analyzes the number, obtains the group ID, and transmits it to the base station, the base s...

Abstract

This invention relates to group system call method, which comprises the following steps: main call starting group calls; basic station forming relative address through mapping relationship according to main call number or group label and to directly call user in basic station; basic station establishing call business channel for main call and called users for business matching. This invention needs not group transfer codes analysis and conversion through relationship between call number and address to call users on basic station side.

Description

technical field [0001] The present invention relates to trunking communication system, such as the trunking system of CDMA (Code Division Multiple Access) 2000 standard, the trunking system of GSM (Global System for Mobile Communications) standard, the trunking system of TD-SCDMA (Time Division Synchronous CodeDivision Multiple Access Time Division Synchronous Code Division Multiple Access) standard trunking system. Background technique [0002] The trunking communication system based on mobile communication is a communication system that combines cellular communication technology with a dedicated dispatching communication system and adopts half-duplex communication mode, which can realize fast connection and support group calls (that is, one-to-many call mode) . Such a trunking communication system can be widely used in departments such as enterprises, public security, police, and the military that have high requirements for command and dispatch functions. [0003] Group ...
