<p>PROBLEM TO BE SOLVED: To transmit a message used in IPv6 from an IPv4 network and to continuously hold network connection using IPv6, which is established before movement by permitting an IPv4/v6 moving terminal to add an IPv4 header to the message used in IPv6, so as to transmit it. SOLUTION: When an IPv4/v6 moving terminal 106 moves from an IPv4/v6 network to the IPv4 network, it registers movements to an IPv6 movement- supporting device 107. Thus, the terminal 106 sets the IPv4 address of the supporting device 107 in the message used in the IPv6 as a transmission destination address. The moving terminal 106 adds the IPv4 header where the IPv4 address of the moving terminal 106 that can be used in the IPv4 network being the moving destination is set as the address of a transmission source, so as to transmit it. Thus, communication using IPv6 can executed anew be.</p> |
