A paging method and related devices for trucking communication

Abstract

Embodiments of the present invention disclose a paging method and related device for trunking communication, which are used to shorten initial call latency in trunking communication and reduce air interface resource overheads of a cell, and are well compatible with the existing system architecture. A method provided by the embodiments of the present invention includes: sending, by a user equipment, an information update request to a mobility management entity MME; receiving, by the user equipment, request response information, where the request response information includes a group identifier of a group that the user equipment joins and a group specific discontinuous reception cycle preset by the trunking server; sending, by the user equipment, an information update complete message to the MME; and after the user equipment initiates a trunking service, using, by the user equipment, a minimum value of a default paging cycle broadcast by a cell where the user equipment is located and the group specific discontinuous reception cycle corresponding to the group identifier as a paging cycle, and receiving, according to the paging cycle, group paging sent by the base station.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a paging method and related equipment for trunking communication. Background technique [0002] Trunking communication service refers to a dedicated communication system in which multiple users share and dynamically use a group of wireless channels. Because trunking communication can provide dedicated command and dispatch for group users such as multiple departments and units, trunking communication has a great impact on delay and reliability. etc. Higher requirements. [0003] For trunking communication, the time for a user to initially initiate a trunking service and receive a call authorization instruction is called Initial PTT Latency. How to reduce the call initiation latency of trunking communication has become the focus of the industry. The Long Term Evolution (LTE, Long Term Evolution) technology introduces a discontinuous reception (DRX, Discontinue Recepti...

AI Technical Summary

Problems solved by technology

[0005] In order to save the calling delay of trunking communication to realize fast paging of trunking communication, there is a prior art: a new trunking paging channel is designed, and the trunking paging channel (TPCH, Trunking Paging Channel) passes system message The paging cycle and paging position of the cluster are issued, so that for cells with a large number of groups or a large number of cluster users, the air interface resource overhead is very significant, resulting in low utilization efficiency of wireless resources
