<p>Provided is a heterogeneous network interworking method for a mobile node having multiple network interfaces. When the mobile node moves from a first network to a second network, the method includes transmitting a packet via a first network interface at the first network, before moving to the second network, by setting up a simple IP address, which is a fixed address of the mobile node, as a sender's address in an inner header of the packet, and an IP address assigned actually to the first network interface as a sender's address in an external header; and transmitting a packet via a second network interface at the second network, after moving to the second network, by setting up said simple IP address as a sender's address in the inner header of the packet and an IP address assigned actually to the second network interface as a sender's address in the external header. In other embodiment, the method includes generating a virtual network interface; and adjusting a flow of packet in a link layer so as to make a packet passing through the multiple network interfaces to be transferred to a mobile IP layer through the virtual network interface.</p> |
