Patent ID: 10149147

Abstract:
[Problem] To provide a communication system for simplifying terminal device configuration.[Solution] A communication system comprises a server and a terminal device. The server stores first information in order for the terminal device to communicate, and stores second information in order for the terminal device to connect to a network of the other bases. When the power is turned on in a normal operation, the terminal device connects to the network by using network information in a non-volatile memory unit, obtains the first information from the server, and writes the same in a volatile memory unit. Thus, the terminal device starts operation. When the power is turned on by using a particular operation, the terminal device connects to the network by using the network information in the non-volatile memory unit, obtains network information of the other bases from the server, and stores the same in the non-volatile memory unit. Thus, it is possible to connect to the network of the other bases.
