METHOD FOR IMPLEMENTING TRUNK SERVICE BASED ON LONG TERM EVOLUTION AND TRUNK USER TERMINAL

摘要

A method and trunk user terminal for implementing a trunk service based on LTE is disclosed. The trunk user terminal includes: a first monitoring unit, configured to monitor a trunk paging channel (TPCH); a group call request unit, configured to initiate a group call; a second monitoring unit, configured to: after the first monitoring unit monitors a group call message through the TPCH, monitor a trunk group control channel (TGCCH) on a network side to obtain configuration information of a trunk group traffic channel (TGTCH) issued on the TGCCH; and a third monitoring unit, configured to establish a local TGTCH bearer based on the configuration information to monitor the TGTCH. In the embodiments of the present invention, a logical channel is added at a trunk UE end, so as to implement a group call process of a trunk UE to other trunk UEs in a cell, implement a point-to-multipoint call, avoid establishment of a plurality of dedicated bearers, and meet the communication demands of an LTE trunk service.
