Abstract
Systems and methods for providing fast handoff support by transferring information are provided. Additionally, a generic protocol message format is presented which allows the transfer of information used in the handoff. The generic protocol allows a gateway to request contexts or session information and send information that allows tunnel setup and mapping to other connections. The session, tunnel, and mapping information allow the gateways to switch packet processing operations without causing disruption to the packet flow. Further, in inter-gateway handoffs or inter-access network handoffs, fast and seamless handoffs are provided so the mobile station keeps the same IP address and the session continues.
