FIELD: radio engineering and communications.SUBSTANCE: invention relates to wireless communication and provides a method of anonymously reporting minimisation of drive test (MDT) measurements. According to 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 user equipment (UE) to a trace collection entity (TCE) if MDT data anonymity configuration indicates MDT measurements are to be reported anonymously at TAC level; sends an international mobile subscriber identification (IMSI) or an international mobile equipment identity and software version (IMEISV) of UE to TCE, if MDT data anonymity configuration indicates other information, for example, trace, is adopted for anonymously reporting MDT measurements.EFFECT: present invention enables an MME to send different identities of UE to TCE according to different requirements for anonymity to implement anonymous reporting of MDT measurements.20 cl, 1 tbl, 7 ex, 9 dwg |
