Abstract: 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.

Abstract: A method for detecting a cause of radio link failure (RLF) or handover failure, in which the first base station triggers a handover process for the UE, and the mobility or handover information of the UE in the source cell is sent to a second base station. After the second base station receives the RLF report of the UE, the second base station can determine cause of a failure according to the RLF report of the UE and the mobility or handover information of the UE in the source cell. Other methods detect a cause of radio link failure (RLF) or handover failure. Application of the methods can improve the accuracy of determining the cause of the RLF or handover failure, improve efficiency of MRO and improve system performance.
