Patent number: 7929556Abstract: A method is disclosed, by which a local mobility anchor (LMA) In a proxy mobile IP network can perform address assignment for a mobile node in cooperation with network address translation, so that the mobile node can be configured with a private HoA. In one embodiment, the LMA obtains the NAI of a mobile node (MN) that is: (i) operating as an IPv4 host and (ii) seeking entry to the network as its home network. The LMA identifies a DHCP server located in the network and serving at least one NAT, and sends it a request message in which the ClientId is set equal to the NAI of the mobile node. The LMA receives a private HoA from the DHCP server, which it forwards in a PBA message to a mobile access gateway (MAG) connected to the MN.Type: GrantFiled: April 29, 2009Date of Patent: April 19, 2011Assignee: Alcatel LucentInventors: Telemaco Melia, Bruno Mongazon-Cazavet
