Abstract: 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.

Abstract: The present invention provides a method for correctly establishing a local IP access (LIPA or SIPTO@LN) service. The method includes: obtains a subscribed service type and a device capabilities type of a UE, judging whether the subscribed service type is consistent with the device capabilities type, and establishing a LIPA or SIPTO@LN service for the UE in response to a determination that the subscribed service type is consistent with the device capabilities type, or rejecting establishing the service in response to a determination that the subscribed service type is consistent with the device capabilities type. The present invention guarantees a LIPA or SIPTO@LN service be established correctly, thereby can better satisfy service requirements of users and implement optimal network resources allocation.

Abstract: A method for supporting indication of a failure event to a source access system is provided. The method includes notifying, by the source access system, information of a source cell to a target access system, routing, by the target access system, a message to the base station or the base station controller of the source access through a core network by use of the information of the source cell received from the source access system when the target access system needs to transmit a message to the source access system. By use of the method provided by the present disclosure, a problem of mobility robustness optimization (MRO) among different radio access technology (RAT) may be notified to the source access system, so as to avoid impact for a terminal, reduce operator configuration.
