Abstract: The present invention provides a method for establishing an interface and communication between a relay node (RN) and a core network. The method may include: a base station sends an IP address of a control plane node of the core network to an RN; the RN initiates a process for establishing an interface with the control plane node corresponding to the IP address. Alternatively, the method may include: a base station sends an IP address and an identification of a control plane node of the core network to an RN; the base station sends an IP address and an identification of the RN to the control plane node of the core network; the RN and the node communicate with each other by using information of each other received from the base station. The method for establishing an interface and communication between an RN and a core network according to the present invention realizes transparent transmission of access layer signaling between a relay node and a core network via a base station, which reduces complexity of the process when the RN is in movements, makes it easier to support multiple access techniques, and reduces the complexity in network configurations.

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.
