Patent ID: 8139538

Claim:
In a Mobile Router supporting Mobile IP, the Mobile Router having one or more networks associated therewith, a method of establishing a route between one or more nodes associated with one of the networks of the Mobile Router and a Correspondent Node, the method comprising: composing a Home Test Init (HOTI) message on behalf of at least one of the nodes, the HOTI message including a care-of address field identifying a care-of address of the Mobile Router and a Home Address field identifying a Home Address of the one of the nodes, wherein the one of the nodes is a node that does not support Mobile IP; sending the HOTI message from the Mobile Router to a Correspondent Node via a Home Agent supporting the Mobile Router; sending a Care-of Test Init (COTI) message to the Correspondent Node on behalf of the at least one of the nodes, the COTI message including a care-of address field identifying the care-of address of the Mobile Router and a Home Address field identifying the Home Address of the one of the nodes; receiving a Home Test (HOT) message from the Correspondent Node; receiving a Care-of Test (COT) message from the Correspondent Node; automatically sending a binding update message to the Correspondent Node, wherein the binding update message identifies a home address of the one of the nodes; and receiving a binding acknowledgement message from the Correspondent Node, thereby enabling a binding between the one of the nodes and the Correspondent Node to be generated such that data packets transmitted between the one of the nodes and the Correspondent Node can be routed between the one of the nodes and the Correspondent Node without being routed via the Home Agent.
