Abstract
A method and apparatus for processing mobile-IP registration messages. Upon receipt of a mobile-IP registration request (RRQ) message that designates a care-of address matching the mobile-IP home agent's IP address, the RRQ would be dropped. Alternatively, before deciding to drop such an RRQ, the invention may further involve determining whether the home agent is currently functioning as a foreign agent for the requesting mobile node, which would justify the care-of address matching the home agent's IP address. If the home agent is not currently functioning as a foreign agent for the mobile node, then the RRQ would be dropped. On the other hand, if the home agent is currently functioning as a foreign agent for the mobile node, then RRQ processing would proceed as normal.
