TRUNKING COMMUNICATION SYSTEM, TRUNKING SERVER, ACCESS NETWORK AND TRUNKING COMMUNICATION METHOD

摘要

A trunking communication system, a server, an access network and a trunking communication method are disclosed. The system includes a trunking management server and an access network, the trunking management server includes a trunking call service control module and a connected trunking call media gateway module, where: the trunking call media gateway module is configured to receive service data sent through the access network by a trunking UE, and forward the service data according to a communication type of the service data for implementing user plane communication of the trunking UE; and the trunking call service control module is configured to receive a communication request sent through the access network by a trunking UE, and perform call control and bearer management on the trunking UE according to a communication type of the communication request for implementing control plane communication of the trunking UE.

主权项

1. A trunking communication system, comprising:
a trunking management server comprising a trunking call service control module and a connected trunking call media gateway module; an access network comprising a mobile management entity (MME), an access network gateway and a base station (eNodeB) which communicate with each other, the access network gateway comprising a multimedia broadcast multicast service (MBMS) gateway and a public data network (PDN) gateway that communicate with the trunking call media gateway module, wherein the trunking call media gateway module communicates with the access network gateway; wherein the trunking call media gateway module is configured to receive service data sent through the access network by a first user equipment (UE) among at least one trunking UE, and forward the service data according to a communication type of the service data for implementing user plane communication of the at least one trunking UE; and wherein the trunking call service control module is configured to receive a communication request sent through the access network by a second UE among the at least one trunking UE, and perform call control and bearer management on the at least one trunking UE according to a communication type of the communication request for implementing control plane communication of the at least one trunking UE.
