Trunking communication system, and paging method, network side device and terminal of such system

Abstract

The invention relates to the communication field, and discloses a trunking communication system, and a paging method, a network side device and a terminal of such system. In the invention, during a period of time in a group paging period, the least amount of paging messages needed for carrying all the paging information in the group paging period are continuously transmitted, and in each group paging period, the terminal starts to monitor the paging messages from the time of starting to transmit the local cell paging messages; in the local group paging period, the terminal monitors the paging channel no more after monitoring the last paging message. Moreover, the paging information carrying the higher-priority group is transmitted preferentially, so that the terminal can immediately perform the related processing procedure of the higher-priority group without continuing to monitor the subsequent group paging messages in the local group paging period. Additionally, the transmitting time of the group paging messages of a co-channel cell or an adjacent-channel cell in the trunking communication system is configured in different periods of time in the group paging period.

Description

technical field [0001] The invention relates to the communication field, in particular to a cluster communication system in the communication field. Background technique [0002] In trunking communication, the speaker terminal initiates a point-to-multipoint group service establishment request by pressing the PTT key, and the network periodically sends paging messages on the paging channel after receiving the group establishment request, and other terminals in the group Periodically monitor the paging message on the paging channel. When the terminal receives the paging message of the group it belongs to, it will monitor the service information on a downlink channel allocated by the network according to the instruction of the paging message and the predefined channel configuration, and enter the Group business. In different trunking communication systems, the names of paging messages or paging channels can be different, but their common characteristics and functions are: the...

Problems solved by technology

[0007] Moreover, since the order of sending paging messages is not adjusted according to the priority of group services, it is not conducive to improving the connection speed of high-priority group services. Paging of low-priority group services is processed first and then switched back to the processing of high-priority group services, resulting in waste of channel resources and processing resources

[0008] In addition, in the prior art, group paging messages may be sent at the same time in cells of the same frequency or adjacent frequency cells, and interference between them may reduce the success rate of terminals receiving paging messages and affect group services. connection speed and success rate
