ABSTRACT:
A system and method of providing mobility between Internet Protocol (IP) based packet networks is disclosed. The disclosed system and method permits user equipment to roam from one IP based packet network to a second IP based packet network, without any interruption in data communications. Wide area network mobility is achieved through the modification of existing protocols to include additional network gateway addressing information.
