Abstract

A method for maintaining connectivity between a mobile node and a corresponding node when the mobile node connects to a foreign network, where the foreign network and the home network are Internet protocol version 6 (IPv6) networks but the corresponding node is an Internet protocol version 4 (IPv4) node. The method includes receiving at the home agent node an IPv6 care-of address, determining that the IPv6 care-of address belongs to the foreign network and that the foreign NAT64 node has a prefix to generate virtual IPv6 addresses and sending a prefix binding request message to a home NAT64 node to bind the prefix to the home address of the mobile node for translation between IPv6 and IPv4.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from the earlier filing date of co-pending US Provisional Patent Application No. 61 / 308,660, filed February 26, 2010. technical field [0003] Embodiments of the invention relate to the ability of mobile devices to move between networks. In particular, embodiments of the present invention relate to methods and systems for enabling IPv6 native mobile devices to migrate to foreign IPv6 networks and maintain connectivity with IPv4 corresponding nodes. Background technique [0004] Mobile Internet Protocol Version 6 (MIPv6) allows a mobile device to maintain a persistent connection with another device that supports Internet Protocol Version 6. Two independent communication modes are supported: bidirectional tunneling (bidirectional tunneling, BT) mode and routing optimization (RO) mode. The RO mode dynamically updates the routing of traffic between a mobile device or "Mobile Node" (MN) an...
