Group call establishment method based on digital trunked communication system, network side equipment

Abstract

The invention discloses a group call establishment method based on a digital trunked communication system, a network side equipment. The method comprises steps that a network side receives a group call request message which is from a calling terminal and aims at a special group; uplink resources are distributed to the calling terminal, wireless uplink special bearing is established, downlink resources are distributed to all the trunked terminals in the group on an origination evolution base station (eNodeB), wireless downlink sharing bearing is established, T1 bearing is established for all the trunked terminals in the group of the origination eNodeB, regional gathering is realized according to present positions of the members in the group, paging is initiated to the members in the group, downlink resources are distributed to all the trunked terminals having paging responses in the group of the origination eNodeB, wireless downlink sharing bearing is established, T1 bearing is established for all the trunked terminals having the paging responses in the group of the origination eNodeB; the calling terminal is granted with a word right, the called trunked terminals are notified, and calling establishment is accomplished. The group call establishment method realizes resource establishment according to a present position of a user and carries out group call.

Description

technical field [0001] The invention relates to the technical field of trunking communication, in particular to a group call establishment method and network side equipment based on a digital trunking communication system. Background technique [0002] The trunking communication system is a dedicated wireless communication system for specific industry applications developed to meet the command and dispatch needs of industry users; in the trunking communication system, a large number of wireless users share a small number of wireless channels, and the command and dispatch is the main application; the trunking communication system is a A multi-purpose, high-performance wireless communication system. [0003] The trunking communication system has experienced a development process similar to that of the cellular mobile communication system: [0004] The first generation trunking communication system is an analog trunking communication system, which mainly supports voice communi...

AI Technical Summary

Problems solved by technology

In terms of data transmission capability and multimedia service support capability, the current narrowband digital trunking communication system is still relatively backward; the current narrowband digital trunking communication system has not reached the data transmission rate of the order of Mbps, nor can it be very good in terms of spectrum utilization and coverage. good to meet needs
