Patent ID: 8582534

Claim:
A method for registration of a mobile node on a foreign network comprising the steps of: receiving a registration request message at a local mobility anchor relating to the mobile node connected to said foreign network, said registration request message including a mobile node identifier, an access type identifier that indicates that communication access type used to connect to the mobile node, a handover indicator that specifies whether the new registration request is associated with a handover to a new access interface on said foreign network or a handover to a new foreign network, and an interface identifier that indicates the specific access interface being used to connect to the mobile node; correlating the information received in the first registration request against information on a cache entry table associated with the local mobility anchor; creating an appropriate entry on the cache entry table depending on whether a handover to a new foreign network is detected or a handover to a new access interface on the previously connected foreign network is detected; and transmitting a registration response from the local mobility anchor with an appropriate network prefix depending on whether said handover to a new foreign network is detected or said handover to a new access interface on said foreign network is detected.
