Estimating the term…
A mobile IP registration solution for mobile nodes (108-111) of a wireless communication system (100) eliminates the need for sending (208) solicitation messages or receiving (210) advertisement messages from foreign agents (118). A mobile node receives an IP address of a foreign agent from a control message upon roaming into a new site or zone and attempting (304) to acquire a channel. Substantially immediately upon acquiring (306) a channel, the mobile node determines (308) whether to send a proxy MIP advertisement. If not, the mobile node retrieves (310) the foreign agent IP address and forwards (312) the foreign agent IP address to a processing element (e.g., layer 3 processing element). If a proxy MIP advertisement will be sent, the mobile node retrieves (314) the foreign agent IP address and a static capabilities list associated with the foreign agent, constructs (316) a proxy MIP advertisement and forwards (318) the proxy MIP advertisement to a processing element (e.g., layer 3 processing element). Upon receiving the foreign agent IP address or proxy MIP advertisement, the processing element constructs (320) a mobile IP registration request using the foreign agent IP address. The registration request is sent (322) to a home agent (130), along with a care of address, such that the home agent may tunnel packets targeted to the mobile nodes via the care of address while they are at the visited site or network.
