Abstract
A gateway device which mutually converts communication protocols among a subscriber network including a base station wirelessly housing a mobile terminal and an Internet Protocol processor to bring an interface from the base station into an Internet Protocol process, a public switched telephone network and a packet communication network, includes a synchronized network terminating unit which terminates the public switched telephone network to generate the in-device signal, a packet network terminating unit which terminates the packet communication network to generate the in-device signal, a subscriber network terminating unit which houses the base station via the interface to which the Internet Protocol process is applied and terminates the subscriber network to generate the in-device signal, and an exchange unit which exchanges in-device signals each generated from the synchronized network terminating unit, the packet network terminating unit and the subscriber network terminating unit.
