Abstract: A method for supporting fast recovery of a User Equipment (UE) includes performing, by a serving base station, UE context synchronization for one or more other base stations in a related small cell cluster when a UE accesses the serving base station, performing, by a base station that the UE performs a radio resource control (RRC) connection re-establishment, the RRC connection re-establishment for the UE according to UE context saved in a synchronization process. The present also discloses another method and system for supporting UE fast recovery. By applying the technical solution disclosed by the present disclosure, when the UE moves in a small cell scenario, the UE can be recovered quickly in the case of a failure, so as to avoid the UE returns to an idle mode, avoid data loss, guarantee business continuity, and improve UE experience.

Abstract: Methods and apparatus are provided for path switching between an evolved Node B (eNB) and a Mobile Management Entity (MME). The eNB transmits a Path Switch Request message informing that a User Equipment (UE) has changed cells, to the MME. The Path Switch Request message includes an eNB UE S1AP ID, a Tracking Area Identifier (TAI), and cell Identifier (ID). The eNB UE S1AP ID uniquely identifies UE association over an S1 interface within the eNB. The eNB receives a Path Switch Request Acknowledge message including an MME UE S1AP ID and the eNB UE S1AP ID, from the MME. The MME UE S1AP ID uniquely identifies UE association over an S1 interface within the MME. The TAI corresponds to a cell in which the UE is located.
