Method for obtaining hearing person movable station information from network in group calling/group playing procedure

Abstract

This invention discloses a method for obtaining listener mobile station information by a network side in the process of multi-call / multicast suitable for the cluster communication system based on the public network, in the multi-call / multicast region of the network side, a specialized control channel assigned by the local area is used in reporting information by the listener mobile stations in the group, which is shared by all mobile stations in the group, after setting up a multi-call / multicast, the time slot is used as the assigning unit in an assigned special control channel to distribute time slot sub-channels for it, the listener mobile stations in the group reports AB to the network side at different positions, which gets information of the mobile stations in the group based on the AB.

Description

technical field [0001] The present invention relates to a communication method of a trunking communication system based on a public communication network, in particular to a method for obtaining listener mobile station information on the network side during group calling or multicasting in the trunking communication system. Background technique [0002] The trunking communication system is a relatively economical and flexible command and dispatch communication system developed in recent years. It is widely used in government agencies, energy transportation, airport terminals, industrial and mining enterprises, fire police, water conservancy and military units to meet The need for internal communication within the unit. [0003] Initially, the trunking communication system adopts the cluster private network to build a network. However, since each group independently builds a cluster private network, the technology and production and testing among the groups are not unified, ...

AI Technical Summary

Problems solved by technology

[0007] Therefore, during the process of group call / multicast in GSM-R, the network side cannot obtain the information of the listener mobile station, whether the listener mobile station participates in the group call / multicast and the process of participating in the group call / multicast network side can not know

Furthermore, it is not convenient for the trunking department to schedule the communication of mobile stations in the group when performing group calls / multicasting, and it is also impossible to check the presence of mobile stations in each group. call / multicast service needs
