Embodiment Construction
[0025] The embodiment of the present invention provides a method for establishing a group call, which is used to reduce signaling interaction in the process of establishing a group call, thereby reducing the time delay of establishing a group call, and improving the efficiency of establishing a group call.
[0026] The network architecture of the TD-LTE broadband multimedia cluster provided by the embodiment of the present invention is as follows figure 1 As shown, the system includes user equipment (UE), evolved base station (eNB), trunk mobility session management entity (TMSE, TrunkingMobilitySessionEntity), home subscriber server (HomeSubscriberServer, HSS), scheduling server (Server), scheduling console and Operation and maintenance of several parts of the station.
[0027] Under the system architecture, the core network adopts the idea of centralization, and the functions of core network equipment are unified by TMSE. TMSE directly controls all TD-LTE base station equi...
