Group call channel access method, system and equipment

Abstract

This invention discloses an access method, a system and a device for accessing multicall channels, which can access UE in point call to multicall channels quickly and accurately. In this invention, when a network side initiates multicall to a UE having point call, it transmits a message of releasing said point call to the UE and takes the channel description information of multicall, after the UE receives the message, it releases the channel occupied by the point call to access the multicall channel based on the channel description in the message, in which, before the network side sends said message to said UE, it judges if the PRI of the call is greater than the preset threshold to send said message to said UE if so.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to group call access technology. Background technique [0002] The trunking communication system is a mobile communication system used for group dispatching and command communication, and is mainly used in the field of professional mobile communication. The available channels of the system can be shared by all users of the system. It is a multi-purpose and high-efficiency wireless dispatching communication system for sharing resources, sharing costs, and sharing channel equipment and services. [0003] As an advanced mobile command and dispatch system, trunking communication works in half-duplex mode with shared channels, and the number of users in the group is not limited. Trunking communication provides a wealth of service types, including single call, group call, function number addressing, dynamic reorganization, multiple priorities, remote kill / activation, environment mon...

AI Technical Summary

Problems solved by technology

If the decision is to exit the ongoing point call and join the group call, the UE needs to perform a point call channel release process first, and then a group call access process, so the response speed of the UE is relatively slow

[0007] On the other hand, if the mobile phone does not set the priority of automatic answering, you can choose whether to answer group calls with any priority, so that the advantages of group calls in command and dispatch cannot be reflected, and it is also impossible to completely avoid human-made calls. Misoperation, ignoring group calls with high priority
