Abstract
A method and gateway node for routing IP traffic to and from a mobile terminal able to connect to the Internet via two or more gateway nodes. A multi-addressing multi-homing protocol is implemented at each gateway node on behalf of the mobile terminal. The gateway nodes share protocol state information to enable gateway nodes to update state information at the corresponding node when the mobile terminal changes gateway nodes.
