  The stationary wireless device 2 has, for example, a printing function for image data, and prints image data transmitted from the portable wireless device 3 by the first wireless communication unit 4. The function possessed by the stationary wireless device 2 is not limited to the printing function. For example, a recording function for an optical disk such as a CD-R or a DVD-R may be provided, and image data transmitted from the portable wireless device 3 by the first wireless communication unit 4 may be recorded on the optical disk. For example, the stationary wireless device 2 may be installed in a store or the like, and a plurality of stationary wireless devices 2 may be installed in one store. In addition, there may be a plurality of stores where the stationary wireless device 2 is installed.

  The portable wireless device 3 includes a third wireless communication unit (first wireless communication unit) 21, an identification information generation unit 22, a fourth wireless communication unit (second wireless communication unit) 23, a display unit 24, and display control. Part 25.

  The third wireless communication unit 21 performs wireless communication with the stationary wireless device 2 using the first wireless method when the authentication process with the stationary wireless device 2 is successful.

  The identification information generation unit 22 generates identification information for identifying the first wireless communication unit 4 of the stationary wireless device 2 that performs wireless communication in the third wireless communication unit 21. The identification information generation unit 22 generates this identification information using unique information unique to the mobile wireless device 3.

  The fourth wireless communication unit 23 receives the password necessary for the authentication process in the third wireless communication unit 21 from the stationary wireless device 2 by the second wireless method, and receives the identification information generated by the identification information generation unit 22. It transmits to the stationary radio apparatus 2 by the second radio system.

  The portable wireless device 3 is a portable electronic device such as a mobile phone, a smartphone, a tablet terminal, a portable PC, a digital camera, etc. possessed by the user.

  In the following, an example in which image data is transmitted from the portable wireless device 3 to the stationary wireless device 2 and each image data is printed by the stationary wireless device 2 will be described. As described above, the stationary wireless device 2 is a portable wireless device. Other services such as recording the image data transmitted from the apparatus 3 on a recording medium such as an optical disk, and displaying the transmitted image data on a large screen display may be performed.

  FIG. 2 is a flowchart of the radio communication system 1 according to the present embodiment. This flowchart is a processing procedure when the user of the portable wireless device 3 visits a store where the stationary wireless device 2 is installed and uses the image data printing service provided by the stationary wireless device 2. It is assumed that application software (hereinafter simply referred to as an application) for the printing service is installed in the portable wireless device 3 in advance.

  First, the user activates this application (step S1). FIG. 3 is a diagram showing an example of the initial screen of the application. On the initial screen of FIG. 3, a selection button b1 of “Wi-Fi easy connection”, a selection button b2 of “password input method”, and a selection button b3 of “move to setting screen” are displayed.

  Among the selection buttons b1 to b3, a characteristic one is “Wi-Fi easy connection” selected by the selection button b1, and the processing procedure when the selection button b1 is selected will be described in detail below. . Note that the “password input method” selected by the selection button b2 allows the user to input a password and performs authentication for wireless communication between the first wireless communication unit 4 and the third wireless communication unit 21. It is. “Move to setting screen” selected by the selection button b3 is for selecting identification information of the first wireless communication unit 4 in accordance with a message on the setting screen.

  In the flowchart of FIG. 2, it is determined whether or not the selection button b1 has been selected (step S2). When the selection button b1 is selected, the process proceeds to step S3 and subsequent steps, and when another selection button b2 or b3 is selected, FIG. This flowchart is terminated.

  When the selection button b1 is selected, for example, a second screen as shown in FIG. 4 is displayed (step S3). In the second screen, a message “Please hold the device over NFC” is described. According to this message, when the user holds the portable wireless device 3 over the reader unit 6 of the stationary wireless device 2 (step S4), the stationary wireless device 2 transmits the password to the portable wireless device 3 in the second wireless method. The portable wireless device 3 transmits identification information to the stationary wireless device 2 (step S5).

  Thereby, both the stationary wireless device 2 and the portable wireless device 3 can possess identification information and a password necessary for wireless communication in the first wireless system. Since the wireless communication range in the second wireless system is sufficiently narrow, the identification information and the password can be exchanged only between the portable wireless device 3 and the stationary wireless device 2 held over the reader unit 6 of the stationary wireless device 2. Yes, security can be improved.

  The identification information that the portable wireless device 3 transmits to the stationary wireless device 2 is generated by the identification information generating unit 22 in the portable wireless device 3. Since the identification information generation unit 22 generates identification information using unique information unique to the portable wireless device 3, even if another portable wireless device 3 exists near the original portable wireless device 3. The stationary wireless device 2 can perform wireless communication with the original portable wireless device 3 by the first wireless method based on the received identification information, and can prevent the portable wireless device 3 from being spoofed.

  FIG. 5 is a diagram illustrating an example of a bit string of identification information. In the example of FIG. 5, the leading p bit of the identification information is information specifying the type of the stationary wireless device 2 that is the communication destination, and the next q bit is unique information of the portable wireless device 3, The r bits are random information. The p-bit information on the leading side is not essential, but for example, the code information when requesting the printing service, the code information when requesting the recording service to the recording medium, and the like are determined in advance. The wireless device 2 is convenient because it can determine what service the user wants from only p-bit information.

  As shown in FIG. 5, by including the unique information of the portable wireless device 3 in the identification information, unique identification information that can be uniquely identified can be generated. Therefore, the stationary wireless device 2 can perform wireless communication only with the specific portable wireless device 3 by the first wireless method. Note that the identification information in FIG. 5 is an example, and the order of the bit strings and the information included in the bit strings may be arbitrarily changed.

  On the other hand, the password generation unit 7 in the stationary wireless device 2 generates an arbitrary password having a predetermined number of characters. Since the password is authenticated in combination with the identification information, the password itself may be duplicate information.

  When step S5 in FIG. 2 is completed, the stationary wireless device 2 performs a wireless communication line connection establishment process by the first wireless method using the acquired identification information and password (step S6). In this connection establishment process, the authentication unit 8 performs an authentication process using the identification information and the password, and the connection establishment unit 9 does not complete the connection establishment process unless the authentication process is successful.

  When the connection establishment process is completed, the stationary wireless apparatus 2 notifies the portable wireless apparatus 3 that the connection establishment process has been completed (step S7). Thereby, for example, a third screen shown in FIG. 6 is displayed on the portable wireless device 3. On the third screen in FIG. 6, a message “Wi-Fi connection has been completed” is displayed.

  Thereafter, a fourth screen for selecting image data is automatically displayed on the display unit 24 of the portable wireless device 3 (step S8). FIG. 7 is a diagram showing an example of the fourth screen. On the fourth screen, thumbnail images of the image data stored in the portable wireless device 3 are displayed, and arbitrary image data and the number of prints can be individually selected from the thumbnail images.

  When the user finishes selecting arbitrary image data and the number of prints and touches the selection end button b4 in the fourth screen, a fifth screen displaying a list of the selected image data and the total number of prints is displayed ( Step S9). FIG. 8 is a diagram showing an example of the fifth screen. When the user touches the transmission button b5 in the fifth screen, the selected image data is transmitted to the stationary wireless device 2 by the first wireless method (step S10).

  Since the first wireless system is a high-speed wireless line such as a wireless LAN or Bluetooth, even large-capacity data such as image data can be transmitted in a relatively short time. Also, wireless LAN has a wider wireless communication range than close proximity wireless communication such as NFC or Bluetooth Low Energy (Bluetooth LE), so once the identification information and password are exchanged using the second wireless method, Since the image data can be transmitted without holding the portable wireless device 3 over the stationary wireless device 2, user convenience is improved.

  Thereafter, the user operates a button indicating that the transmission of the image data has been completed according to the menu on the display screen of the stationary wireless device 2 (step S11). Note that the user may instruct the end of transmission of image data on the screen of the portable wireless device 3 instead of instructing on the screen of the stationary wireless device 2.

  When instructed by the user to end image data transmission, the stationary wireless device 2 cuts off the connection of the wireless communication line by the first wireless method (step S12).

  Thereafter, a sixth screen for selecting a print type is displayed on the display unit 12 of the stationary wireless device 2 (step S13). FIG. 9 is a diagram showing an example of the sixth screen. On the sixth screen, there are a button b6 for selecting printing individually for each image data, a button b7 for selecting an index print, and a button b8 for selecting a divided print for printing two pieces of image data side by side. It is displayed. When the user selects any button, the display unit 12 displays a seventh screen for selecting a print size (step S14). FIG. 10 is a diagram showing an example of the seventh screen. On the seventh screen, for example, a print size such as L plate or 2L plate is selected. Note that steps S13 and S14 may be performed before and after selecting image data in step S8. Thereafter, an eighth screen for payment processing is displayed (step S15).

  The print type and print size may be selected on the display unit 24 of the portable wireless device 2.

  When the above-described flowchart of FIG. 2 is executed, a plurality of portable wireless devices 3 may be held over the reader unit 6 of one stationary wireless device 2 almost simultaneously. In this case, the stationary wireless device 2 adopts the identification information received first by the second wireless method, and this identification information is sent to the portable wireless device 3 other than the portable wireless device 3 that transmitted the identification information. It is transmitted from the stationary wireless device 2 via the second wireless method, and each portable wireless device 3 performs wireless communication using the first wireless method over the common wireless communication line using this identification information. Also good. Accordingly, the stationary wireless device 2 can perform wireless communication with a plurality of portable wireless devices 3 in parallel, and does not have to wait for each portable wireless device 3.

  In FIG. 1, when the password and the identification information are exchanged between the stationary wireless device 2 and the portable wireless device 3 by the second wireless method, the password and the identification information are transmitted and received as they are, but the security is further enhanced. For this purpose, it is desirable to encrypt and transmit the password and identification information. In this case, it is necessary to provide the encryption units 14 and 26 in both the stationary wireless device 2 and the portable wireless device 3.

  FIG. 11 is a block diagram illustrating a schematic configuration of the wireless communication system 1 including the encryption units 14 and 26. The encryption unit 14 in the stationary wireless device 2 encrypts the password generated by the password generation unit 7 using, for example, a shared key shared with the portable wireless device 3 and passes the second wireless method. To the portable wireless device 3. Similarly, the encryption unit 26 in the portable wireless device 3 encrypts the password generated by the identification information generating unit 22 using the shared key described above, and transmits it to the portable wireless device 3 via the second wireless method. To do.

  Thus, in this embodiment, when the portable wireless device 3 is held over the stationary wireless device 2, the password required for wireless communication in the first wireless method is transferred from the stationary wireless device 2 to the portable wireless device in the second wireless method. While transmitting to the apparatus 3, the identification information which identifies the radio | wireless communication line of the 1st radio | wireless communication part 4 and the portable radio | wireless apparatus 3 is transmitted from the portable radio | wireless apparatus 3 to the stationary radio | wireless apparatus 2 by a 2nd radio system. As a result, both the portable wireless device 3 and the stationary wireless device 2 can acquire the identification information and the password in a state in which security is ensured, and it is possible to prevent the risk of other wireless devices acquiring the identification information and the password without permission. Even if another portable wireless device 3 located near the portable wireless device 3 acquires the password from the stationary wireless device 2, the identification information transmitted from the original portable wireless device 3 to the stationary wireless device 2 is the portable wireless device. Since it is generated using the unique information of the device 3, it is possible to prevent the portable wireless device 3 other than the original portable wireless device 3 from performing wireless communication with the stationary wireless device 2 by the first wireless method. Therefore, there is no possibility that another wireless device arbitrarily acquires the image data transmitted from the portable wireless device 3 to the stationary wireless device 2, and secure wireless communication is possible.

  Further, according to the present embodiment, it is not necessary for the user himself / herself to manually input identification information and a password, thereby saving the user's trouble.
