Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a connection management technique of radio network mobility procedures for releasing SIPTO@LN PDN connection when UE moves away from a coverage area of a local gateway (L-GW).

SOLUTION: An evolved packet core node (EPC node) receives notice of a mobility procedure to user equipment (UE) determines whether to release packet data network connection (PDN connection) by a local gateway (L-GW) of the UE transmits any of a detach request message or a session deletion request message in response to determination to release the PDN connection by the L-GW and thereby starts a process of releasing the PDN connection by the L-GW.
