The present invention discloses a method and apparatus for updating a local gateway (LGW) address, capable of solving the problem of updating an LGW address in a situation of mobile relay (MRN) PGW repositioning during an MRN handover process. The method comprises: a destination donor NodeB receiving local gateway address assignment information; according to the local gateway address assignment information, if the destination donor NodeB determines that an IP address is required to be assigned to a local gateway co-located in a mobile relay node, then assigning an IP address to the local gateway; and sending the IP address of the local gateway to a service gateway. An apparatus, located in the destination donor NodeB, comprises a receiving module, an assigning module, and a sending module. Another apparatus, located in the mobile relay node, comprises a judgment module and a storage module. Another apparatus, located in the service gateway servicing a UE, comprises a receiving module and an updating module. By adopting the method and apparatus of the embodiments of the present invention, it guarantees the continuity of an S5 connection, thus guaranteeing service continuity of a terminal. |
