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; and
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 configured to communicate with the trunking call media gateway module, wherein the trunking call media gateway module is configured to communicate 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;
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;
wherein the trunking call media gateway module is configured to:
communicate with the MBMS gateway through an SGmb-i interface, and
communicate with the PDN gateway through an SGi interface.
