  The stationary wireless device 2 has, for example, a print function of image data, and prints the image data transmitted from the portable wireless device 3 by the first wireless communication unit 4. The function possessed by the stationary radio apparatus 2 is not limited to the printing function. For example, the recording function to an optical disc such as CD-R or DVD-R may be provided, and the image data transmitted from the portable wireless device 3 by the first wireless communication unit 4 may be recorded on the optical disc. For example, stationary radio apparatus 2 may be installed in a store or the like, and a plurality of stationary radio apparatuses 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 mobile 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. And 25.

  When the authentication processing with the stationary radio apparatus 2 is successful, the third wireless communication unit 21 performs wireless communication with the stationary radio apparatus 2 by the first wireless method.

  The identification information generation unit 22 generates identification information that identifies 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 the identification information using unique information unique to the portable 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 the identification information generated by the identification information generation unit 22. It transmits to the stationary radio apparatus 2 by the second radio method.

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

  Although 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 below, as described above, the stationary wireless device 2 is A service for recording image data and the like transmitted from the device 3 on a recording medium such as an optical disk, and other various services such as displaying the transmitted image data on a large screen display may be performed.

  FIG. 2 is a flowchart of the wireless 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 a print service of image data provided by the stationary wireless device 2. It is assumed that application software for the print service (hereinafter, simply referred to as an application) is installed in the mobile wireless device 3 in advance.

  First, the user activates this application (step S1). FIG. 3 is a view showing an example of the initial screen of the application. In 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.

  The characteristic one of the selection buttons b1 to b3 is “Wi-Fi easy connection” selected by the selection button b1. In the following, the processing procedure when this selection button b1 is selected will be described in detail . 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. The “move to setting screen” selected by the selection button b3 is for selecting the identification information of the first wireless communication unit 4 in accordance with the message on the setting screen.

  In the flowchart of FIG. 2, it is determined whether or not the selection button b1 is selected (step S2). If it is selected, the process proceeds to step S3 and thereafter, and if another selection button b2 or b3 is selected, FIG. End the flowchart of.

  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 a password to the portable wireless device 3 by the second wireless method, The portable wireless device 3 transmits the 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 scheme. Since the wireless communication range in the second wireless method is sufficiently narrow, the identification information and the password may be exchanged only between the portable wireless device 3 held over the reader unit 6 of the stationary wireless device 2 and the stationary wireless device 2 Yes, and improve security.

  The identification information that the portable wireless device 3 transmits to the stationary wireless device 2 is generated by the identification information generation unit 22 in the portable wireless device 3. Since the identification information generation unit 22 generates identification information using unique information specific 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 in the first wireless method based on the received identification information, and can prevent spoofing of the portable wireless device 3.

  FIG. 5 is a diagram showing an example of a bit string of identification information. In the example of FIG. 5, the leading p bits of the identification information is information for identifying the type of the stationary wireless device 2 which is the communication destination, and the next q bits are the unique information of the portable wireless device 3 The r bits are random information. The information on the leading p-bit is not essential, but for example, it may be determined by determining in advance code information for requesting printing service, code information for requesting recording service on a recording medium, etc. The wireless device 2 is convenient because it can determine what kind of service the user desires by using only p-bit information.

  As shown in FIG. 5, by including the unique information of the portable wireless device 3 in the identification information, it is possible to generate uniquely identifiable unique identification information. Therefore, the stationary wireless device 2 can perform wireless communication with the specific mobile wireless device 3 in the first wireless scheme. The identification information in FIG. 5 is an example, and the order of the bit strings and the information contained 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 of 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 of FIG. 2 is completed, the stationary radio apparatus 2 performs connection establishment processing of a wireless communication line by the first wireless method using the acquired identification information and password (step S6). In this connection establishment process, the authentication unit 8 performs the 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 succeeds.

  When the connection establishment process is completed, the stationary radio apparatus 2 notifies the portable radio apparatus 3 that the connection establishment process is completed (step S7). Thereby, for example, a third screen shown in FIG. 6 is displayed on the mobile wireless device 3. On the third screen of FIG. 6, a message that "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 mobile wireless device 3 (step S8). FIG. 7 is a view showing an example of the fourth screen. On the fourth screen, thumbnail images of image data stored in the portable wireless device 3 are displayed, and it is possible to individually select arbitrary image data and the number of printed sheets from among them.

  When the user finishes selecting the desired image data and the number of printed sheets, and touches the selection end button b4 in the fourth screen, a fifth screen is displayed that displays a list of the selected image data and the total number of printed sheets ( Step S9). FIG. 8 is a view showing an example of the fifth screen. When the user touches the send button b5 in the fifth screen, the selected image data is sent to the stationary wireless device 2 by the first wireless method (step S10).

  The first wireless method is a high-speed wireless line such as a wireless LAN or Bluetooth, and therefore, even for large-volume data such as image data, data transmission can be performed in a relatively short time. Also, since wireless LAN has a wider wireless communication range than proximity wireless communication such as NFC and Bluetooth Low Energy (Bluetooth LE), once the identification information and password are exchanged by the second wireless method, the user Since the image data can be transmitted without holding the portable wireless device 3 to the stationary wireless device 2, the usability for the user is improved.

  Thereafter, the user operates a button to the effect that transmission of the image data has been completed according to the menu on the display screen of the stationary wireless device 2 (step S11). The user may instruct the end of the transmission of the 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, stationary radio apparatus 2 shuts down the connection of the wireless communication line by the first wireless method (step S12).

  After that, the sixth screen for selecting the print type is displayed on the display unit 12 of the stationary radio apparatus 2 (step S13). FIG. 9 is a diagram showing an example of the sixth screen. In the sixth screen, there are a button b6 for selecting printing individually for each image data, a button b7 for selecting index printing, and a button b8 for selecting division printing for printing two sheets of image data side by side. It is displayed. When the user selects one of the buttons, a seventh screen for selecting a print size is displayed on the display unit 12 (step S14). FIG. 10 is a diagram showing an example of the seventh screen. In the seventh screen, for example, a print size such as L or 2 L is selected. Steps S13 and S14 may be performed before and after selection of image data in step S8. Thereafter, an eighth screen for payment processing is displayed (step S15).

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

  When executing the flowchart of FIG. 2 described above, a plurality of portable wireless devices 3 may be held by 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 by the second wireless method first and transmits the identification information to the portable wireless device 3 other than the portable wireless device 3 that has 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 by the first wireless method on a common wireless communication line using this identification information. It is also good. As a result, the stationary wireless device 2 can perform wireless communication concurrently with the plurality of portable wireless devices 3 and does not have to make each portable wireless device 3 wait.

  Although FIG. 1 shows an example in which the password and the identification information are exchanged as they are 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 security is further enhanced. In order to do this, it is desirable to encrypt and transmit the password and the identification information. In this case, the encryption units 14 and 26 need to be provided in both the stationary wireless device 2 and the portable wireless device 3.

  FIG. 11 is a block diagram showing a schematic configuration of the wireless communication system 1 including the encryption units 14 and 26. As shown in FIG. 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 transmits the encrypted data via the second wireless method. And transmit 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 generation unit 22 using the above-described shared key, and transmits the encrypted password to the portable wireless device 3 via the second wireless method. Do.

  As described above, in the present embodiment, when the portable wireless device 3 is held over the stationary wireless device 2, the password necessary for wireless communication in the first wireless method is transferred from the stationary wireless device 2 to the portable wireless device using the second wireless method. While transmitting to the device 3, identification information for identifying a wireless communication channel between the first wireless communication unit 4 and the portable wireless device 3 is transmitted from the portable wireless device 3 to the stationary wireless device 2 by the second wireless method. As a result, both the mobile wireless device 3 and the stationary wireless device 2 can acquire the identification information and the password in a state where security is secured, and it is possible to prevent the possibility that other wireless devices freely acquire the identification information and the password. Even if another portable wireless device 3 near the portable wireless device 3 acquires a password from the stationary wireless device 2, the identification information that the original portable wireless device 3 transmits to the stationary wireless device 2 is the portable wireless device Since the information is generated using the unique information of the device 3, it is possible to prevent the possibility that the portable wireless device 3 other than the original portable wireless device 3 performs wireless communication with the stationary wireless device 2 in the first wireless method. Therefore, there is no risk that another wireless device acquires the image data transmitted by the portable wireless device 3 to the stationary wireless device 2, and secure wireless communication is possible.
