Abstract
In data communication utilizing amateur radio, communication via Internet can be performed. A radio terminal belonging to an internal network can communicate with a radio terminal belonging to another internal network via the Internet. Each radio terminal has a callsign, and a gateway has a global IP address and a table which associates each radio terminal with the global IP address of a corresponding gateway. When receiving from a radio terminal, information addressed to a radio terminal in another internal network, the gateway sends the received information to the Internet by addressing it to the global IP address of the gateway of the internal network to which the destination radio terminal 33 belongs with reference to the table. When receiving information from the Internet, the gateway sends the received information to a radio terminal specified by the callsign of a receiver.
