(Third embodiment)
FIG. 8 is a flowchart showing an example of the operation of the wireless communication system 1 according to the embodiment of the present invention.
The wireless communication system 1 of the present embodiment includes the same information processing apparatus 300 as that of the above embodiment of FIG. 5 and the same mobile terminal 200 as that of FIG. Note that the wireless communication system 1 of the present embodiment can be configured as the information processing apparatus 100 and the mobile terminal 200 of the above-described embodiment of FIG. Hereinafter, description will be made with reference to FIGS. 1 to 3, 5, 6, and 8.

The wireless communication system 1 (FIG. 5) of the present embodiment operates generally as follows.
In the wireless communication system 1 of the present embodiment, the wireless communication unit 102 (FIG. 5) of the information processing device 300 generates a QR code after the generation unit 104 (FIG. 5) of the information processing device 300 generates (Step S305 in FIG. 8). ), An access point search is started (step S309 in FIG. 8). Then, the wireless communication unit 102 of the information processing apparatus 300 establishes wireless communication with the mobile terminal 200 (FIG. 5) in which a function as an access point is constructed (step S313 in FIG. 8). The wireless communication unit 102 of the information processing device 300 causes the generation unit 104 of the information processing device 300 to generate a new password every time wireless communication with the mobile terminal 200 is disconnected (YES in step S317 in FIG. 8), A new QR code is generated in the information to be recorded in the code (step S305 in FIG. 8), and the access point search is started again (step S309 in FIG. 8). Then, the wireless communication unit 102 of the information processing device 300 establishes wireless communication with the mobile terminal 200 in which a function as an access point is constructed (step S313 in FIG. 8).

  More specifically, first, in the information processing apparatus 300, a program according to the embodiment of the present invention is started (step S301 in FIG. 8). Then, the reception unit 302 (FIG. 5) of the information processing device 300 displays the setting screen 400 (FIG. 6) on the display device 152 (FIG. 2) of the information processing device 300, prompts the user to operate, The setting is accepted and stored in the setting file (step S303 in FIG. 8). As described above, a preset connection condition can also be used. If a setting file is determined in advance, step S301 in FIG. 8 can be omitted. Further, the process of step S303 in FIG. 8 may be executed in response to a user setting change request.

  Then, the generation unit 104 (FIG. 5) of the information processing apparatus 300 generates a QR code according to the setting file set in step S303 in FIG. 8 (step S305 in FIG. 8). Then, the presentation unit 106 (FIG. 5) of the information processing device 300 displays the QR code on the display device 152 (FIG. 2) (step S307 in FIG. 8).

  On the other hand, it is assumed that the mobile terminal 200 is initially in a standby state (step S321 in FIG. 8). And a user operates the operation part 232 (FIG. 3) of the portable terminal 200, and starts the camera of the imaging part 240 (FIG. 3) of the portable terminal 200 (YES of step S323 of FIG. 8).

When the user releases the shutter and photographs the QR code displayed on the display device 152 by the information processing apparatus 300, the code reading unit 204 (FIG. 5) of the portable terminal 200 reads the photographed QR code (step S325 in FIG. 8). ).
And the acquisition part 206 (FIG. 5) of the portable terminal 200 analyzes a QR code, and acquires the information of a connection condition (step S327 of FIG. 8).

  During this time, in the information processing apparatus 300, the wireless communication unit 102 (FIG. 5) searches for an access point accessible by the own apparatus (step S309 in FIG. 8). For example, on the display device 152 of the information processing device 300, a message or icon for notifying the user that “access point is being searched” may be displayed on the screen.

  The communication control unit 208 (FIG. 5) of the mobile terminal 200 constructs a function as an access point of the information processing device 300 based on the connection condition information acquired by the acquisition unit 206 of the mobile terminal 200 (step of FIG. 8). S329).

  Then, the wireless communication unit 102 of the information processing apparatus 300 searching for the access point finds the mobile terminal 200 (YES in step S311 in FIG. 8), accesses the mobile terminal 200, and connects to the network 3 (FIG. 1). A connection is requested (step S313 in FIG. 8). The communication control unit 208 (FIG. 5) of the portable terminal 200 establishes a connection with the information processing apparatus 300, and further establishes a connection to the network 3 (step S331 in FIG. 8).

  Then, wireless communication between the wireless communication unit 102 of the information processing device 300 and the wireless communication unit 202 (FIG. 5) of the mobile terminal 200, and wireless communication between the wireless communication unit 202 of the mobile terminal 200 and the network 3. Are respectively performed (step S315 in FIG. 8 and step S333 in FIG. 8).

  If the wireless communication between the information processing apparatus 300 and the portable terminal 200 is disconnected (YES in step S317 in FIG. 8), the information processing apparatus 300 returns to step S305 in FIG. In step S305 in FIG. 8, the generation unit 104 of the information processing device 300 generates a new password, generates a QR code including the generated new password information again, and receives it by the presentation unit 106 of the information processing device 300. hand over.

  On the other hand, in the portable terminal 200, when the wireless communication between the information processing apparatus 300 and the portable terminal 200 is disconnected (YES in step S335 in FIG. 8), the process returns to step S321 in FIG. . Then, the camera of the imaging unit 240 is awaited for activation (step S323 in FIG. 8), and the QR code presented by the information processing apparatus 300 is newly read.

  That is, in the wireless communication system 1 of the present embodiment, when the wireless communication between the information processing apparatus 300 and the mobile terminal 200 is established and then disconnected, the generation unit 104 of the information processing apparatus 300 is again configured. Generates a new password, generates a QR code including the generated password information, presents it by the presenting unit 106, reads the QR code by the code reading unit 204 of the mobile terminal 200, and re-enters the communication control unit 208. Try to connect.

  As described above, according to the wireless communication system 1 of the present embodiment, the same effects as those of the above-described embodiment can be obtained. Further, when wireless communication is disconnected, a new password is generated for each connection and wirelessly generated. Since communication is resumed, safety is improved.
