Abstract: Embodiments of the present invention provide a handover method performed by a source access network device, which includes: sending, a handover request or a WLAN offload request to a UE, so that the UE determines information about a target AP according to AP information corresponding to a target RAN and information about a currently accessed AP, and sends a WLAN offload binding request carrying the information about the target AP to a target access network device in the target RAN, so as to complete a RAN handover, where the handover request or the WLAN offload request includes the AP information corresponding to the target RAN, and the AP information corresponding to the target RAN is information about an AP in a WLAN that covers, together with the target RAN, a location of the UE; and receiving a handover response or a WLAN offload response returned by the UE.

Abstract: The present invention discloses a local network and a method for establishing a connection between a local gateway and a home base station therein. As regards a newly proposed home base station network architecture 1, a mobility management network element receives L-GW information sent by the home base station, selects an L-GW which is located in the same local network as the home base station at least according to the received L-GW information and then informs the L-GW, through an S-GW, of establishing a PDN connection and a tunnel bearer with the home base station, thereby providing a local IP access for a UE. As regards a newly proposed home base station network architecture 2, no direct interface is arranged between the L-GW and the S-GW, the mobility management network element directly selects a corresponding L-GW for establishing a PDN connection for the UE.
