<p>The invention relates to mobility management in a mobile Internet protocol network. The network comprises a local mobility domain access router and a wireless access point operationally connected to the local mobility domain router, where the wireless access point is proxying a mobile node. Data packets destined to the mobile node and entering the local mobility domain router hold a proxy care-of address assigned to the mobile node as a routing address. The proxy care-of address is replaced with a local address assigned to the wireless access point, where the local address is invisible to the mobile node. With the procedure of the invention, the local mobility domain router acts as a wireless attachment point for the mobile node, thus decreasing signalling over the air interface when the mobile node moves in the network.</p> |
