ABSTRACT:
Systems and methods to manage network access (e.g., IPv4 and IPv6) and layer 3 mobility are provided. This can allow mobility management to be moved from a mobile node's stack to the access gateway, simplifying the stack and providing fast handoffs. The mobility management at an access gateway further allows a mobile node to keep its dynamically assigned IP address for the duration of a call session and through handoffs. The placement of access gateways in a domain of trust allows security information to be passed between access gateways in a handoff so that the security associations do not need to be re-authenticated with the mobile node. One or more of the above mobility management features can be used to provide a fast and seamless handoff for a mobile node.
