Abstract
Methods and apparatuses for allowing mobile nodes to have access to mobility functions after being attached to their home networks are disclosed. The invention allows a home agent to authenticate a registration request and validate a DHCP-acquired home address even if no mobile bindings currently exist. Typically, a home agent will not create mobility bindings if a mobile node attaches itself to a home agent network segment. By using either cached information or DHCP resources, the home agent can approve a registration request.
