Method for establishing an interface and communication between a relay node and a core network

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