Abstract

The embodiment of the invention provides a cluster communication method, a cluster communication device, a dispatcher, a terminal and a system. The method comprises the following steps: a group establishment notification message is sent according to a group establishment request message, the group establishment notification message comprises a group identifier of the group to be established and atemporary mobile group identifier TMGI of a multicast channel of the group to be established, and the TMGI is allocated to the dispatcher and sends group data in a multicast mode on the multicast channel corresponding to the TMGI. According to the method provided by the embodiment of the invention, the TBCP connection message is not sent to the group user in a unicast manner during group establishment, so that the group establishment time delay is reduced, the signaling storm is avoided, dispatching system resources are saved, and the reliability of cluster communication is improved.

Description

technical field [0001] Embodiments of the present invention relate to trunking communication technology, and in particular, to a trunking communication method, device, dispatcher, terminal and system. Background technique [0002] The trunking communication service refers to the trunking communication network composed of the trunking communication system with technical characteristics such as channel sharing and dynamic allocation, and provides dedicated command and dispatching and other communication services for group users such as multiple departments and units. The trunking communication system is a multi-purpose, high-efficiency wireless dispatching communication system that shares resources, shares costs, and shares channel equipment and services. It is an advanced mobile dispatching system and represents the development direction of a dedicated mobile communication network, one of the communication systems. [0003] With the continuous development of communication tec...
