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 supporting group handover, which is applied to a User Equipment (UE) in communication with a network via a Relay Node (RN), is provided. The method includes a base station (e.g., an S-DeNB) hands over an RN to a base station (e.g., a T-DeNB) and the S-DeNB hands over the UE served by the RN to the T-DeNB, wherein the handovers are performed simultaneously or separately. The various embodiments of the present disclosure provide a base station supporting group handover. The technical scheme set forth in the present disclosure can reduce an unnecessary signaling procedure, the possibility of network congestion, and can reduce the signaling procedure of handover when group handover occurs, so as to reduce the failure of the handover process and enhance the continuity of service.

Abstract: The present invention discloses a method for proximity discovery among user equipments (UEs). The method includes: a UE registers with a device to device (DTD) server and obtains DTD default resources from a received registration response. When the UE is a user to be discovered and is not in coverage, it sends a discovery message on the DTD default resources. When the UE is a discovering user, it receives the discovery message on the DTD default resources. The present invention also discloses a device. With the technical solution of the present invention, it is not only possible to support a discovering service and a to-be-discovered service when the UE is in coverage, but also to support the same services when the UE is not in coverage.
Abstract translation: 本发明公开了一种在用户设备（UE）之间进行邻近发现的方法。 该方法包括：UE向设备（DTD）服务器注册，并从接收到的注册响应获取DTD默认资源。 当UE是被发现并且没有覆盖的用户时，它会在DTD默认资源上发送一个发现消息。 当UE是发现用户时，它会在DTD默认资源上收到发现消息。 本发明还公开了一种装置。 利用本发明的技术方案，当UE处于覆盖状态时，不仅可以支持发现服务和待发现的业务，还可以在UE不在覆盖范围内时支持相同的业务。
