Gateway device and control method for communication with IP and IPV6 protocols
A non-IP device holds an interface ID defined by Ipv6. A gateway generates and holds an Ipv6 address for the non-IP device. The gateway serves to convert the protocol of a packet destined to the non-IP device from a portable telephone or a personal computer coupled to an internet into the protocol for a network connected to the non-IP device and transmit the packet to the non-IP device.
