Abstract

Provided are improved systems and methods for establishing dynamic Home Agent (HA) addresses and Home Addresses (HoA) for mobile stations operating on Foreign Networks according to the Mobile IPv6 standard, thereby providing the ability to dynamically assign IP addresses for mobile stations within a Home Network rather than using static or pre-provisioned IP addresses. The present invention provides new Type 7 Router Solicitation and Type 8 Router Advertisement messages to modify the existing Mobile IPv6 standard. The Type 7 and Type 8 messages enhance Mobile IPv6 to permit a mobile station in a Foreign Network to obtain through the Foreign Network a dynamically assigned Home Agent (HA) address and Home Address (HoA) from the Home Network for the mobile station.

Description

technical field [0001] The present invention relates generally to mobile Internet Protocol (IP) communications, and more particularly to methods for dynamically determining a Home Agent (HA) address and a Home Address for a mobile station in a foreign network operating in accordance with a Code Division Multiple Access (CDMA) architecture (HoAs). Background technique [0002] Internet Protocol (IP) addressing has previously been defined by a 32-bit standard commonly referred to as Internet Protocol Version 4 (IPv4 or IPv4 Protocol). More recently, with the proliferation of more and more Internet users and devices, the limitations of IPv4 have created the need for larger network spaces defined by the next generation of Internet protocols. The 128-bit IP addressing standard, version 6 of the Internet Protocol (IPv6 or IPv6 Protocol), has been developed to enable the increased demand for network space. Specifically, IPv6 defines a larger network space by exponentially increas...
