摘要
A systern for handing off a mobile node includes a mobile node and a target foreign agent. To effectuate a handoff of the mobile node from an anchor foreign agent to the target foreign agent, a tunnel can be established therebetween such that data packet(s) sent between the mobile node and a correspondent node pass between the target foreign agent and the anchor foreign agent through the tunnel. After the tunnel is established, the mobile node can register with the target foreign agent to thereby bind the mobile node to the target foreign agent such that data packet(s) sent between the mobile node and the correspondent node pass through the target foreign agent to the correspondent node independent of the anchor foreign agent and the tunnel. Thereafter, the target foreign agent can close the tunnel between the target foreign agent and the anchor foreign agent.
