Abstract: The present specification proposes a method of displaying a terminal involved in public disaster safety communication in a single base station that has a constraint on a normal backhaul connection. Even when the backhaul connection is disconnected, it is possible for a terminal to communicate by using an X2 connection between base stations, but there is a limitation in that it is difficult for a terminal to find the position of another terminal because a connection between the base station and an evolved packet core (EPC) is disconnected. Thus, there is a need for a method to solve this limitation. Whether there is a backhaul connection between a first base station and the EPC is detected, and when a backhaul connection is not detected, a first ID is allocated to a terminal in the service area of the first base station and the first ID allocated is transmitted to a second base station. When there is a backhaul connection between the first base station and the EPC, a globally unique temporary identifier (GUTI) of the terminal in the service area of the first base station is received from a mobility management entity (MME). Then, whether there is a backhaul connection between the first base station and the EPC is detected, and when a backhaul connection is not detected, the GUTI of the terminal in the service area of the first base station is transmitted to the second base station.

Abstract: A method and apparatus for performing trace recording in a wireless communication system is provided. It is assumed that an evolved NodeB (eNB) is shared by a first operator and a second operator. The UE receives an indication, which allows collecting minimization of drive tests (MDT) logs of a user equipment (UE) of the second operator, from a mobility management entity (MME) of the second operator. Upon collecting the MDT logs, the UE transmits a trace record based on the collected MDT logs to a trace collection entity (TCE) of the first operator.
