Abstract: A communication method is provided. The communication method includes receiving, by a Mobile Management Entity (MME), information accessed by a User Equipment (UE) through a Relay Node (RN), and sending, by the MME, a Tracing Region Identification (TAI) list of an RN cell where the UE is located to the UE. A network device and an access network device are further provided. By sending a TAI list of an RN cell to the UE, when TAI(s) of the cell are contained in the TAI list of the relatively stationary UE, the UE does not need to initiate an uplink TAU process, and thereby unnecessary signaling and network jamming can be reduced, and at the same time, paging efficiency and network performance can be improved.

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.

Abstract: A method of automatically adjusting a mobility parameter is disclosed. In the method, through sending the peer eNB the message containing different handover thresholds, the relative adjustment value corresponding to each threshold and/or the target frequency information to which the handover threshold is adjusted, the peer eNB can learn that which threshold is adjusted by the source eNB, so as to adjust the corresponding parameter. In this way, the accuracy and efficiency of automatic adjustment of the mobility parameter are improved, and the destination eNB can adjust the mobility parameters of all cells working on the same frequency, so as to guarantee that the adjustment of the mobility parameter for handing over from the source cell to the destination cell working on the same frequency has no negative influence. By the method of the present invention, the automatic adjustment of mobility parameter between different frequencies or different access systems becomes available and can be supported in the case of the self-optimization of mobile load balance and the self-optimization of mobile robustness, so as to improve the performance of mobile communication system.
