1. A communication method of acquiring a binding ID when a mobile node performs handover to a second network without any network-based mobility control protocol after a binding ID of the mobile node to connect to a first network with a network-based mobility control protocol is set for a proxy node of the first network, the method comprising:

  • a step in which the mobile node transmits a binding ID allocation request message to the proxy node of the first network;

    a step in which the proxy node receives the binding ID allocation request message and transmits the binding ID allocation request message to a management node for managing the binding ID;

    a step in which the management node receives the binding ID allocation request message, generates and stores the binding ID, and transmits the binding ID to the proxy node;

    a step in which the proxy node receives the binding ID and transmits, to the mobile node, allocation information indicating that the binding ID is allocated;

    a step in which the mobile node transmits a request message for the binding ID to the management node based on the allocation information when the mobile node performs handover from the first network to the second network;

    a step in which the management node receives the request message for the binding ID from the mobile node; and

    a step in which the management node transmits the binding ID to the mobile node.
