Method for route optimization with dual mobile IPv4 node in IPv6-only network

摘要

A method for route optimization with a dual mobile IPv4 node (26) in an IPv6-only network (22) is provided. The method includes the operations of: receiving a visited IPv6 address from a router when the dual mobile node (26) is connected to the IPv6-only network (22); updating a home agent (12) with the IPv6 address; deregistering a binding update with a correspondent node (18) via the home agent (12); updating the correspondent node (18) with an IPv6 address; checking the reachability of packets directly to the correspondent node (18) using its IPv6 address; the mobile node (26) starting sending, to the CN, data packets tunneled in an IPv6 packet once the reachability is verified; and the correspondent node (18) sending tunneled data packets directly to an IPv6 address of the mobile node (26).
