Document Type and Number:
Japanese Patent JP2008507875
Kind Code:
A
Abstract:
A system for handing off a mobile node includes a mobile node and a target agent. The mobile node can communicate with an anchor agent, and can also be handed off from the anchor agent. The mobile node can establish a physical-layer connection between the mobile node and a target base station associated with the target agent. Also, the target agent can establish a tunnel between the target agent and the anchor agent. Thereafter, the mobile node can establish a link-layer connection between the mobile node and the target agent via the anchor agent and the tunnel. Then, the mobile node can register with the target agent to thereby bind the mobile node to the target agent such that data packet(s) pass through the target agent, across the link-layer connection and the physical-layer connection, and independent of the anchor agent and the tunnel.
