Cluster communication system, user equipment thereof, control device and dynamic group calling method

Abstract

The invention discloses a cluster communication system, user equipment thereof, a control device and a dynamic group calling method. The method for performing dynamic group calling in the cluster communication system comprises the following steps: when calling user equipment establishes a group calling service, acquiring a calling user equipment identifier and set region range information, and sending a first request to the control device; and when called user equipment receives a group calling establishing request sent by the control device, acquiring position information of the called user equipment, judging whether a position of the called user equipment is within a region range or not, and participating into the group calling service and switching to a service channel when the position of the called user equipment is within the region range, wherein the group calling establishing request comprises the calling user equipment identifier, the region range information, an allocated group identifier and the service channel. Through implementation of the technical scheme of the invention, a group calling establishing process is relatively simple, and field real-time and rapid establishment of the group calling service is facilitated. Moreover, dynamic group establishing and calling fusion is realized; intermediate links are reduced; and the flow is simplified.

Description

technical field [0001] The present invention relates to the trunking field, in particular to a trunking communication system and user equipment, a control device, and a dynamic group call method. Background technique [0002] The method of initiating a group call in a trunking system is generally that the terminal initiates a call to a pre-assigned fixed group, or the dispatcher first initiates a dynamic reorganization. After the reorganization is successful, the terminal in the dynamic group can initiate a call to the dynamic group. When the initiator needs to initiate a group call in a specified area, for example: [0003] (1) Terminals or dispatching stations with dispatching function or dynamic reorganization function authorization need to perform dynamic reorganization according to the terminals in a specific geographical area, and make group calls to the dynamic group; [0004] (2) In the event of earthquakes, fires, production accidents, terrorist attacks, etc., such...
