Abstract: The present application discloses a method for supporting SIPTO. The method includes, when a target base station is in a local home network, the target base station sends an identity of the local home network to which the target base station belongs to an MME. The method also includes that the MME determines whether a UE has moved out of the local home network to which the source base station belongs according to the local home network id of the source base station and the local home network id of the target base station. By applying this application, the MME is capable of determining whether the UE has moved out of the local belongs network to which the source base station belongs accurately, therefore a bearer disconnection process can be correctly triggered, resources can be timely released or an SGW can be accurately selected.

Abstract: A communication method is provided. The communication method includes receiving, by a Mobile Management Entity (MME), information accessed by a User Equipment (UE) through a Relay Node (RN), and sending, by the MME, a Tracing Region Identification (TAI) list of an RN cell where the UE is located to the UE. A network device and an access network device are further provided. By sending a TAI list of an RN cell to the UE, when TAI(s) of the cell are contained in the TAI list of the relatively stationary UE, the UE does not need to initiate an uplink TAU process, and thereby unnecessary signaling and network jamming can be reduced, and at the same time, paging efficiency and network performance can be improved.

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.
