A method enabling an relay node (RN) to support multiple wireless access techniques is provided, which includes: a mobility management element (MME) requests a DeNB to establish evolved radio access bearers (ERAB) of EUTRAN and indicates access network information that will be transmitted by each of the ERABs; the DeNB requests an RN to establish radio bearers (RB) and indicates the access network information that will be transmitted by each of the RBs. The above method makes fewer modifications to conventional networks and techniques, guarantees service quality provided for a UE accessing an LTE system, and enables an RN to support access of UEs using multiple access techniques.
