COMMUNICATION METHOD BETWEEN IPV6 MOBILE NODE AND IPV4-BASED NODE USING DSTM IN MOBILE IPV6 ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide a communication method between an IPv6 mobile node and an IPv4-based node using DSTM in a mobile IPv6 environment.;SOLUTION: The present invention is a communication method which can keep direct communication between a mobile node located on an IPv6-based network where mobility is supported, and a node located on IPv4-based network where mobility is not supported, by maintaining a state of communication with the node located on the IPv4-based network although the mobile node, which communicates with the node in the IPv4-based network, moves to an external network. In order to support mobility between the both networks, a DSTM gateway (or DSTM TEP) corresponding to a DSTM border router processes a binding update request received from an IPv6 mobile node (S34-S36).;COPYRIGHT: (C)2007,JPO&INPIT
