Group callback method and device in broadband trunking system and broadband trunking system

Abstract

The invention discloses a group callback method in a broadband trunking system. The method comprises the steps that a sending end sends a first group callback request to a trunking core network; the trunking core network selects a callback receiving end according to the first group callback request; the trunking core network sends a second group callback request to the callback receiving end; andthe callback receiving end receives and stores the second group callback request and calls back a session group in which the sending end is located in response to the second group callback request when a preset condition is satisfied. In the mode, according to the method, the device and the system, the communication efficiency can be improved, demands of related application scenes can be satisfied, and the user experience can be improved.

Description

technical field [0001] The invention relates to the field of trunking communication, in particular to a method, system and device for group callback in a broadband trunking system. Background technique [0002] There are two types of group calls in the existing Mission-Critical Push To Talk (MCPTT) standard: preset group calls and chat group calls. [0003] Among them, after the caller initiates a group call, the preset group call will initiate a call to each called point-to-point, which requires the participation of relevant personnel, and these personnel are not in the group session (the user is in other calls, and the user actively calls from the group before). When withdrawing from the group, etc.), the system will not be able to effectively communicate with these people. [0004] Chat group calls can only be actively joined by the user. When relevant personnel are required to participate, but these personnel are not in the group conversation (the user has not actively ...
