Abstract: A method and a system for processing a Radio Link Failure (RLF) report, where when a User Equipment (UE) encounters an RLF in a first cell controlled by a first evolved base station and selects a second cell controlled by a second evolved base station to re-establish an Radio Resource Connection (RRC), are provided. The method includes sending, by the second evolved base station, the RLF report to every corresponding evolved base station according to the PCI of the first cell having been received from the UE, where the PCI of the first cell, the PCI of a second cell, the CRNTI of the UE in the first cell, and UE authentication information are carried in the RLF report, and authenticating, by every evolved base station the UE according to the UE authentication information. Another method for processing an RLF report, and two methods for adjusting a mobile parameter, are also provided.

Abstract: The present application discloses a method for data forwarding in a small cell system, comprising: sending by a master base station (MeNB) to a target secondary base station (SeNB) information of a source SeNB or a source SeNB cell where a user equipment (UE) is located; determining by the target SeNB whether a direct data forwarding is feasible; notifying, by the target SeNB, the MeNB whether the direct data forwarding is feasible; and determining by the MeNB whether it is a direct data forwarding or an indirect data forwarding. The method for data forwarding provided in the present application may support both the direct data forwarding and the indirect data forwarding based on actual situation of the network, reduce data loss and failure of data forwarding, and improve the efficiency of data forwarding.

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.
