A Realization Method of Temporary Group Call in Digital Trunking System

Abstract

The invention provides a temporary group calling implementation method in a digital trunk system. The temporary group calling implementation method in the digital trunk system comprises the followingsteps: a trunk core network receives group calling establishment request information sent by a calling terminal, wherein the group calling establishment request comprises a specific number; the trunkcore network judges the requested group calling as temporary group calling according to the specific number, sends temporary group user list request information to a location information server and receives the temporary group user list sent by the location information server; the trunk core network creates a temporary group according to the temporary group user list and assigns a temporary groupnumber to the temporary group; the trunk core network pushes the temporary group information to the members in the group; and the trunk core network assigns calling identifiers, establishes the groupcontext, and sends group calling establishment response information to the calling terminal, wherein the group calling establishment response information comprises the temporary group user list. According to the temporary group calling implementation method in the digital trunk system, the calling process does not require a dispatching desk to participate, and does not write to the database, therefore, multiple dynamic regrouping operations in the temporary group calling implementation method in the prior art are avoided, and the process is simplified.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing a temporary group call in a digital trunking system. Background technique [0002] The trunking communication system is a dedicated wireless communication system developed to meet the command and dispatch needs of industry users. It has a wide range of application markets in public safety, transportation, petrochemical, public utilities, and airports and ports. With the continuous development of mobile communication systems in the direction of broadband, at present, B-TrunC (a broadband digital trunking communication system based on LTE technology) has become the main technical system of the next generation trunking system and the national standard of our country. In LTE point-to-point communication On the basis of , in order to provide multimedia cluster scheduling function, the network architecture and interface control protocol are enhanced. With ...
