Abstract
The invention involves a method for achieving local anchoring of a mobile node (MN) in a wireless system comprising a plurality of radio access networks (RANs), a plurality of gateways (GWs), each capable of acting as a serving gateway, and a home server, with each RAN being connected to a GW, and a user profile relating to the MN being stored in the home server. According to the method, when the mobile node has a radio link with a first RAN which is connected to a first GW, the first GW is assigned as a local anchor for the MN, and the user profile relating to the MN in the home server is updated with an indication of the first GW. And when the mobile node moves to a second RAN which is also connected to the first GW, the indication of the first GW is retrieved from the user profile relating to the MN in the home server, and the first GW assigned is kept as a local anchor for the MN, based on the retrieved indication of the first GW.
