Abstract: Provided are a cross-Master eNB (MeNB) switching method and apparatus, and a base station. The method comprises: a target MeNB determines that a UE has already established a selected internet protocol traffic offload (SIPTO)/local internet protocol access (LIPA) service on a secondary eNB (SeNB) before the switching; and the target MeNB retains or releases the SIPTO/LIPA service, wherein the user equipment (UE) is accessed to a source MeNB and the SeNB through dual links before the switching, and the UE is accessed to the target MeNB and the SeNB through the dual links after the switching, and a combined local gateway (L-GW) supporting the SIPTO/LIPA service is configured on the SeNB. By means of the present invention, the problem in the related art of not considering the processing of the SIPTO/LIPA service in the cross MeNB switching process is solved, thereby providing an SIPTO/LIPA service processing method in the cross MeNB switching process.

Abstract: A method and a base station for processing an SIPTO (Selected IP Traffic Offload) connection, the method includes: when a terminal is handed over from a source SeNB (Secondary eNB) to a destination SeNB, receiving, by an MeNB (Master eNB), an interface message from the destination SeNB (11), herein the source SeNB supports a collocated L-GW (Local Gateway); and when a handover success acknowledgement message sent by the destination SeNB is received, triggering, by the MeNB, the source SeNB to notify the L-GW to release an SIPTO@LN (Selected IP Traffic Offload at Local Network) connection (12). Through the embodiments of the present document, the release of the SIPTO@LN connection in a collocated L-GW scenario under a small base station environment can be effectively implemented.

Abstract: The present document discloses a method and apparatus for updating a local gateway (LGW) address. The method may include a destination donor NodeB receiving local gateway address assignment information and, according to the local gateway address assignment information, if the destination donor NodeB determines that an IP address is required to be assigned to a local gateway co-located in a mobile relay node, then assigning an IP address to the local gateway, and sending the IP address of the local gateway to a service gateway. An apparatus, located in the destination donor NodeB, may include a receiving module, an assigning module, and a sending module. Another apparatus, located in the mobile relay node, may include a judgment module and a storage module. Another apparatus, located in the service gateway servicing a UE, may include a receiving module and an updating module.
