Abstract

The disclosed digital swarm communication system comprises: a user terminal, a wireless access network with RNC to create lower share channel as the control command in same subzone and copy the media flow from server to send to the called terminal, and a core network connected to the server of SGSN for calling control and copy or transmission for business media flow. This invention realizes the PTT and PTM business.

Description

technical field [0001] The invention relates to a dedicated mobile communication system in mobile communication, in particular to a digital trunking communication system based on the mobile communication system and a method for realizing trunking services in the mobile communication system. Background technique [0002] Mobile communication can be divided into public mobile communication and private mobile communication. The trunking communication system is a dedicated mobile communication system in which multiple users (departments, groups) share a group of radio channels and use these channels dynamically. The trunking user can talk with a preset person or group of people by pressing the button to talk, which is commonly called push-to-talk (PTT: Push-to-Talk). The trunking communication has the advantages of short call connection time, network High resource utilization and high efficiency are especially suitable for command and dispatch. [0003] Similar to the developme...
