Abstract

A method for realizing a cluster group call session in a Long Term Evolution (LTE) system is described. The method comprises that: an Evolved Packet Core (EPC) establishes uplink and downlink radio bearers of the cluster group call session between a calling User Equipment (UE) and the EPC through a first evolved Node B (eNB) where the calling UE is located; and the EPC establishes a downlink radio bearer of the cluster group call session between a called UE and the EPC through a second eNB where the called UE is located. Simultaneously, a system and an apparatus for realizing a cluster group call session in an LTE system are described. With the method, system and apparatus for realizing a cluster group call session in the LTE system provided in the disclosure, cluster group call session services can be realized in an LTE network, and unified commanding, scheduling and management of a calling user on called users can be realized.

Description

technical field [0001] The present invention relates to trunking communication technology, in particular to a method, system and equipment for realizing trunking group call sessions in Long Term Evolution (LTE). Background technique [0002] The trunking communication system is a mobile dispatching system, which represents the development direction of a dedicated mobile communication network, one of the communication systems. The trunking service provided by it has technical characteristics such as channel sharing and dynamic allocation, and can be used by multiple departments, units and other groups. Users provide communication services such as dedicated command and dispatch. At the end of the 20th century, with the popularization of digital communication systems, trunking communication systems based on digital communication technology have also been widely used. In recent years, with the rapid development of third-generation and even fourth-generation wireless communicati...
