Information processing device, server device, data communication system, data communication method, and computer-readable storage medium storing data communication program

A data communication system in which data is transmitted and received between a server device and an information processing device or devices via a relay device by wireless communication, wherein

• each of the information processing device or devices includes
• an identification information storage unit configured to store terminal identification information for identifying the each of the information processing device or devices;
• a signal receiver configured to receive a broadcast signal containing at least one piece of terminal identification information transmitted from the server device via the relay device;
• a determiner configured to determine whether or not any of the at least one piece of terminal identification information contained in the signal received by the signal receiver corresponds to the stored terminal identification information;
• a connection requester configured to, when the determiner determines that one of the at least one piece of terminal identification information corresponds to the stored terminal identification information, request a wireless connection to the relay device;
• and
• a data communicator configured to transmit or receive data to or from the server device via the relay device by wireless communication, and
• the server device includes
• an identification information storage unit configured to store additional terminal identification information for identifying the information processing device or devices;
• a signal transmitter configured to transmit, via the relay device, a broadcast signal including at least one piece of terminal identification information extracted from the additional terminal identification information;
• and
• a data communicator configured to transmit or receive data to or from the information processing device or devices via the relay device by wireless communication.

A data communication method for transmitting and receiving data between a server device and an information processing device or devices via a relay device by wireless communication, the method comprising:

• a signal transmission step of causing the server device to transmit a broadcast signal containing, at least, at least one piece of terminal identification information extracted from at least one piece of previously stored terminal identification information for identifying the information processing device or devices, via the relay device;
• a signal reception step of causing the information processing device or devices to receive the signal from the server device via the relay device;
• a determination step of causing each of the information processing device or devices to determine whether or not any of the at least one piece of terminal identification information contained in the signal received in the signal reception step corresponds to the previously stored terminal identification information for identifying the each of the information processing device or devices;
• a connection request step of causing each of the information processing device or devices to, when the determination step determines that one of the at least one piece of terminal identification information corresponds to the previously stored terminal identification information for identifying the each of the information processing device or devices, request a wireless connection to the relay device;
• and
• a data communication step of causing the information processing device or devices and the server device to transmit or receive data via the relay device by wireless communication.

A non-transitory computer-readable storage medium storing a data communication program for transmitting and receiving data to and from a server device via a relay device by wireless communication, the program causing a computer to execute:

• receiving a broadcast signal containing at least one piece of terminal identification information transmitted from the server device via the relay device;
• determining whether or not any of the at least one piece of terminal identification information contained in the received signal corresponds to previously stored terminal identification information for identifying an information processing device;
• requesting a wireless connection to the relay device when it is determined that one of the at least one piece of terminal identification information corresponds to the previously stored terminal identification information for identifying the information processing device;
• and
• transmitting or receiving data to or from the server device via the relay device by wireless communication.

An information processing device for transmitting and receiving data to and from a server device via a relay device by wireless communication, comprising:

• an identification information memory configured to store terminal identification information for identifying the information processing device;
• a signal receiver configured to receive a broadcast signal containing at least one piece of terminal identification information transmitted from the server device via the relay device;
• a processing system, including a processor, the processing system being at least configured to:
• determine whether or not any of the at least one piece of terminal identification information contained in the signal received by the signal receiver corresponds to the stored terminal identification information;
• and
• when the determination is made that one of the at least one piece of terminal identification information corresponds to the stored terminal identification information, request a wireless connection to the relay device;
• and
• a data interface configured to transmit or receive data to or from the server device via the relay device by wireless communication.
