Abstract: Embodiments of the present disclosure provide a method for maintaining service continuity in heterogeneous communication system, including: when a bearer is established on a SeNB/SeNB's cell for a UE or the UE tracking area is updated due to a bearer transfer, a MeNB sends a MME a serving identifier of a SeNB/SeNB's cell where the UE is located or a serving identifier of a eNB/cell which a user plane bearer of the UE is on; the MME determines a TA identifier/eNB identifier which the UE bearer is in, including a TA identifier/eNB identifier of the SeNB's cell where the UE is located, according to received serving identifier. On one hand, the MME may determine whether a UE moves out of the local home network according to the TA of the UE, and whether it is necessary to release the SIPTO@LN bearer. On the other hand, the MME may select the SGW according to the TA identifier/eNB identifier and the TA identifier/eNB identifier of a MeNB/MeNB's cell, or according to the TA identifier/eNB identifier where a user plane bearer of the UE is located, and notify the MeNB, so that the MeNB may, according to corresponding notification, establish or remain a UE bearer on the SeNB's cell, or transfer a UE bearer in or out of the SeNB's cell. By adopting above method, the continuity of user plane data may be maintained when a bearer is established on or moved to a small cell.

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.
