Method of anonymously reporting minimization of drive test measurements

摘要

The present invention provides a method of anonymously reporting minimization of drive test (MDT) measurements. According to the method, a mobility management entity (MME) obtains MDT data anonymity configuration which indicates whether MDT measurements are to be reported anonymously at a type allocation code (TAC) level; sends a TAC of a UE to a trace collection entity (TCE) if the MDT data anonymity configuration indicates MDT measurements are to be reported anonymously at the TAC level; sends an international mobile subscriber identification (IMSI) or an international mobile equipment identity and software version (IMEISV) of the UE to the TCE if the MDT data anonymity configuration indicates other information, e.g. Trace, is adopted for anonymously reporting MDT measurements. The present invention enables an MME to send different identities of a UE to the TCE according to different requirements for anonymity to implement anonymous reporting of MDT measurements.

1. A method for anonymously reporting minimization of drive test (MDT) measurements by a mobility management entity (MME), the method comprising:
receiving a cell traffic trace message from an evolved node b (eNB); identifying information related to anonymization of MDT data based on the cell traffic trace message; transmitting a type allocation code (TAC) of a user equipment (UE) to a trace collection entity (TCE) if the information related to the anonymization of the MDT data indicates that the TAC is required; and transmitting an international mobile subscriber identification (IMSI) or an international mobile equipment identity and software version (IMEISV) of the UE to the TCE if the information related to the anonymization of the MDT data indicates that the TAC is not required.
