Abstract

A system for providing redundant home agents comprises a plurality of home agents, the home agents create mobility binding registrations with outside PDSNs. The system also includes a redundant home agent, the redundant home agent is coupled to said plurality of home agents. A home agent control node is coupled to the plurality of home agents and sends registration requests to the home agents. The home agent control node contains a detector for determining a failure in any of the plurality of home agents. The home agent control node also contains a mobility binding registration and downloads the mobility binding registration to the redundant home agent upon the detection of a failure in one of the plurality of home agents.
