Abstract
An embodiment of the invention provides a method for supporting handover. That is, inform a target base station which bear in bearers to be handed over is a Local Internet Protocol (IP) Access (LIPA) bearer, by a source base station. Regarding the LIPA bearer, the target base station sends a message to a corresponding Local Gateway (L-GW), to request the L-GW to update downlink user plane transmission. By adopting the method for supporting handover, provided by an embodiment of the invention, a correct user plane transmission may be established for a User Equipment (UE), to enable a user plane to be correctly established during handover process. Thus, continuity of LIPA service may be guaranteed, and successful handover may be achieved.
