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: Methods and apparatus are provided for path switching between an evolved Node B (eNB) and a Mobile Management Entity (MME). The eNB transmits a Path Switch Request message informing that a User Equipment (UE) has changed cells, to the MME. The Path Switch Request message includes an eNB UE S1AP ID, a Tracking Area Identifier (TAI), and cell Identifier (ID). The eNB UE S1AP ID uniquely identifies UE association over an S1 interface within the eNB. The eNB receives a Path Switch Request Acknowledge message including an MME UE S1AP ID and the eNB UE S1AP ID, from the MME. The MME UE S1AP ID uniquely identifies UE association over an S1 interface within the MME. The TAI corresponds to a cell in which the UE is located.
