Abstract:
1. A method of anonymously reporting minimization of drive test (MDT) measurements, comprising: obtaining, by a mobility management entity (MME), an MDT data anonymity configuration indicating whether a anonymization level of MDT data is a Type Allocation Code (TAC) level; sending, by the MME, a TAC of a user equipment (UE) to a trace collection entity (TCE) if the MDT data anonymity configuration indicates the anonymization level of the MDT data is the TAC level; and if the MDT data anonymity configuration indicates the anonymization level of the MDT data is not the TAC level, sending, by the MME, an international mobile subscriber identification (IMSI) or an international mobile equipment identity and software version (IMEISV) of the UE to the TCE.
