- A method is provided for managing a tunnel when a mobile node moves from an existing visiting network to a visiting network which supports a mobile IP. A mobile node may detect a movement of the mobile node, configure a care-of address (CoA) and thereafter transmit a location registration (Binding Update) message to a home agent. The mobile node may create a second tunnel in the visiting network and set the second tunnel as a receiving-only tunnel while maintaining a first tunnel which is already used in the existing visiting network. The mobile node may receive a location registration completion (Binding Acknowledgement) message from the home agent, change the second tunnel to the tunnel capable of transmitting/receiving by modifying a routing table, and cancel the first tunnel.
