DHCP based home address management of mobile IP clients

摘要

Methods and apparatuses for allowing mobile nodes to have access to mobility functions after being attached to their home networks. 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.
