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

摘要

A method for realizing a cluster group call session in a Long Term Evolution (LTE) system is described. The method comprises that: an Evolved Packet Core (EPC) establishes uplink and downlink radio bearers of the cluster group call session between a calling User Equipment (UE) and the EPC through a first evolved Node B (eNB) where the calling UE is located; and the EPC establishes a downlink radio bearer of the cluster group call session between a called UE and the EPC through a second eNB where the called UE is located. Simultaneously, a system and an apparatus for realizing a cluster group call session in an LTE system are described. With the method, system and apparatus for realizing a cluster group call session in the LTE system provided in the disclosure, cluster group call session services can be realized in an LTE network, and unified commanding, scheduling and management of a calling user on called users can be realized.
