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.
