Abstract
An object of the present invention is to provide a technique capable of promptly and efficiently starting a communication processing when a demand is generated, in a communication system including a terminal for a non-continuous connection. A communication terminal and a device can be connected through a relay device, and when the communication terminal transmits a UDP packet to the device, the relay device receives the UDP packet and transmits a control signal to the device. The device makes a dial-up connection to establish a PPP session, and establishes a TCP connection with the relay device. By using this TCP connection, the communication terminal transmits an inspection instruction file to the device. The device conducts an inspection in accordance with the inspection instruction file, prepares an inspection result file, and returns it to the communication terminal. Then, the device disconnects the TCP connection, the PPP session, and the dial-up line network.
