Title: GATEWAY DEVICE AND COMMUNICATION SYSTEM
Abstract:
The present invention provides a communication network that stably maintains connection to a computer communication network. A gateway device 100A is provided with: a first communication unit 130A for communicating with an electronic device 10; a second communication unit 140A for communicating with a computer communication network INT; a third communication unit 135A for communicating with a gateway device 100B that is different from the gateway device 100A, the communication unit 135A having a communication mode that is different from that of the second communication unit 140A; and a processing unit 120A for controlling communication. The processing unit 120A performs a control so that the electronic device 10 and the computer communication network INT can communicate with each other via the second communication unit 140A when the second communication unit 140A is able to communicate with the computer communication network INT, and performs a control so that the third communication unit 135A is routed through the gateway device 100B, and the electronic device 10 and the computer communication network INT can communicate with each other, when the second communication unit 140A is unable to communicate with the computer communication network INT.
