1. a kind of trunked communication system characterized by comprising cluster management server and access network, the cluster managementServer includes trunked call service control module, and the trunked call media connecting with the trunked call service control moduleGateway module, the access network include mobile management entity MME, access network gateway and base station eNodeB, the MME, instituteIt states access network gateway and the eNodeB is in communication with each other, the access network gateway includes and the trunked call Media GatewayThe public data network PDN Gateway and multimedia broadcast multi-broadcasting business MBMS gateway that module is in communication with each other;

  • The trunked call Media Gateway Module is sent for receiving the UE in cluster user equipment UE by the access networkBusiness datum, the business datum is forwarded according to the communication type of the business datum, to realize the cluster UEUser face communication;

    The trunked call service control module is led to for receiving the UE in the cluster UE by what the access network was sentLetter request carries out Call- Control1 and bearer management to the cluster UE according to the communication type of the communication request, to realizeState the control plane communication of cluster UE;

    The trunked call Media Gateway Module is also used to when the communication type is point-to-multipoint delivery, by the clusterThe business datum that speaker UE in UE is sent is sent to the MBMS gateway;

    And when the communication type is point-to-point communicationWhen, the PDN Gateway is sent by the business datum sent of the speaker UE in the cluster UE;

    The MBMS gateway, the business datum for sending the speaker UE are sent to where the monitoring UE in the cluster UEENodeB so that the eNodeB service data group broadcast that sends the speaker UE monitored where UE is to the monitoringUE;

    The PDN Gateway, for the speaker UE business datum sent to be forwarded in the cluster UE by gatewayCalled UE where eNodeB so that the business datum that eNodeB where the called UE sends the speaker UE is sentTo the called UE.
