METHOD, SYSTEM AND EQUIPMENT FOR REALIZING CLUSTER GROUP CALL SESSION IN LONG TERM EVOLUTION

摘要

Disclosed in an embodiment of the present invention is a method for realizing a cluster group call session in LTE (Long Term Evolution), the method comprises: EPC (Evolved Packet Core) establishing uplink and downlink radio bearers of the cluster group call session between calling UE (User Equipment) and the EPC through a first eNB (evolved node B) where the calling UE is located; and EPC establishing the downlink radio bearer of the cluster group call session between called UE and the EPC through a second eNB where the called UE is located. Simultaneously, also disclosed in an embodiment of the present invention is a system and equipment for realizing a cluster group call session in LTE; by adopting the method, system and equipment for realizing a cluster group call session in LTE disclosed in the present invention, the cluster group call session service can be realized in an LTE network, and unified commanding, scheduling and management of a calling user on called users can be realized.
