Patent ID: 7916721

Claim:
A method comprising: a mobile internet protocol (“mobile-IP”) device obtaining a care-of address; the mobile-IP device receiving bootstrap parameters, wherein the bootstrap parameters include a home address subnet prefix, wherein the home address subnet prefix defines a range of home addresses, and wherein the home address subnet prefix has been assigned to the mobile-IP device by a home agent; the mobile-IP device sending to the home agent a first binding update, wherein the first binding update (i) includes the home address subnet prefix and the care-of address of the mobile-IP device, and (ii) causes the home agent to associate the range of home addresses defined by the home address subnet prefix with the care-of address of the mobile-IP device; and the mobile-IP device broadcasting to an internet protocol version 6 (“IPv6”) node a router advertisement message, wherein the router advertisement message includes the home address subnet prefix, and wherein the router advertisement message causes the IPv6 node to obtain a mobile-IP address based on the home address subnet prefix, wherein the mobile-IP address is a home address of the IPv6 node.
