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.

1. A method for implementing a trunk service based on Long Term Evolution (LTE), comprising:
setting up a Trunk Paging CHannel (TPCH); after a first terminal initiates a group call, a network side correspondingly setting up a Trunk Group Control CHannel (TGCCH) and a Trunk Group Traffic CHannel (TGTCH), and issuing configuration information of the TGTCH through the TGCCH; a second terminal monitoring and finding a group call message of the first terminal through the TPCH, and monitoring the TGCCH to obtain the configuration information; and the second terminal setting up a local TGTCH bearer based on the configuration information to monitor the TGTCH; wherein, the first terminal and the second terminal are trunk user terminals; wherein, the second terminal is in a cell where the first terminal is located, and the second terminal obtains a scrambling code when the second terminal monitors and finding the group call message of the first terminal through the TPCH, to monitor the TGCCH so as to obtain the configuration information; or, the second terminal is in a cell outside a cell where the first terminal is located, and after the second terminal monitors and finds the group call message of the first terminal through the TPCH, the second terminal responds to the group call message to obtain a scrambling code, so as to monitor the TGCCH to obtain the configuration information.
