Abstract

In a Proxy Mobile IPv6 (PMIP) network, a mobile node can roam between different access networks while maintaining a consistent IP address for session continuity. To provide access to a user's home LAN resources, even when the user's mobile node is not directly attached to the home LAN, a local mobility anchor and mobility access gateway are configured to authenticate the mobile node credentials and if authorized, to provide access to the user's LAN resources by via data tunnels and routing table reconfigurations.
