Description

  The present invention relates to a communication system, a communication method, and a wireless communication device, and more particularly to a communication system, a communication method, and a wireless communication device that set setting information.

  In order for a slave unit such as a wireless communication device that performs wireless LAN (Local Area Network) communication to connect to a master unit such as a wireless access point to establish communication, it indicates information necessary for establishing a connection with the master unit. It is necessary to set the setting information in the slave unit. The setting information includes an identifier (SSID: Service Set IDentifier) of the wireless access point, an encryption key for decrypting the encrypted data, and the like. Using this setting information, the slave unit establishes communication with the master unit according to the wireless LAN standard defined by IEEE (The Institute of Electrical and Electronics Engineers) 802.11.

  A technique for easily setting setting information in a wireless communication terminal (child device) is disclosed in Patent Document 1. In the technique disclosed in Patent Document 1, the setting information is converted into a QR code (registered trademark) and displayed on the main body of the wireless communication device (access point). Then, the wireless portable terminal (child device) equipped with the QR code reader reads the displayed QR code with the QR code reader, and sets the setting information embedded in the QR code in its own terminal. As described above, the technique disclosed in Patent Document 1 can easily set the setting information in the slave unit. However, the technique disclosed in Patent Document 1 has a problem that the setting information can be easily stolen because the setting information can be acquired by reading the QR code displayed on the main body of the wireless communication device.

  A technique for solving this problem is disclosed in Patent Document 2. The technique disclosed in Patent Document 2 is to divide a two-dimensional code (corresponding to a QR code) into separate printed materials and manage these printed materials separately. For this reason, in order to acquire the contents (for example, setting information) of the two-dimensional code, it is necessary to read each two-dimensional code (printed material) that is divided and managed separately. For this reason, according to the technique disclosed in Patent Document 2, contents embedded in the two-dimensional code are not easily stolen, and confidentiality is improved compared to the technique disclosed in Patent Document 1.

  Similarly to the technique disclosed in Patent Document 2, the technique disclosed in Patent Document 3 also divides the QR code into two and prints them on separate papers. For this reason, in order to acquire the contents (for example, setting information) of the QR code, it is necessary to correctly align the two sheets. For this reason, when there is only one sheet of paper or when the paper cannot be correctly aligned, the QR code cannot be correctly recognized. For this reason, it is possible to avoid leakage of the contents of the QR code compared to the case where the QR code is printed on one sheet of paper.
