Abstract

IP mobility solution for mobile network(s) combines features of IP multicast and mobile IPv6. The mobile network defines a mobile router (106) attached to one or more mobile network hosts (102). Upon movement of this network from a home network to a foreign network, the router obtains a multicast care of address for the attached network hosts, creating a binding between the mobile subnet prefix and the multicast care of address. The router communicates the binding information to a home agent (150). A correspondent node sends packets to a mobile network nodes home address. They are intercepted by the home agent and tunneled to the router via the multicast care of address. The router receives the packet and forwards it to the targeted mobile network node. Optionally, the router may send a binding update to the correspondent node, therefore, future packets travel the shortest tree, avoiding the overhead of tunneling.
