Method and system for realizing broadband trunking service

Abstract

The invention discloses a broadband trunking service realizing method and a broadband trunking service realizing system. The method comprises the following steps: when the service type of an established trunked call service is transformed from a first type to a second type, a trunked scheduling subsystem modifies a T1 bearer of a trunked call service corresponding to a base station to which group member terminals belongs according to QoS parameters corresponding to the trunked call service of the second type, and notifies the base station to reestablish a downlink shared bearer for the group member terminals managed by the base station; and the trunked scheduling subsystem notifies the group member terminals that the service type of the trunked call service is changed after reestablishment of the downlink shared bearer is finished. With the broadband trunking service realizing method and the broadband trunking service realizing system, diversification and real-time transmission of broadband services can be realized.

Description

technical field [0001] The invention relates to the field of trunking communication systems, in particular to a method and system for realizing broadband trunking services. Background technique [0002] The trunking communication system is a dedicated wireless communication system for specific industry applications developed to meet the command and dispatch needs of industry users. In the system, a large number of wireless users share a small number of wireless channels, and the command and dispatch is the main application. It is a multi-purpose, high-efficiency wireless communication system. [0003] The trunking communication system has experienced a development process similar to that of the cellular mobile communication system: [0004] The first generation trunking system is an analog trunking communication system, which mainly supports voice communication. For example, Actionet system (using MPT-1327 signaling, applied in the 450MHz frequency band), Smartnet system, ...
