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.
