  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of a network to which a wireless LAN setting method of the present invention is applied. Here, a wireless terminal MN as a set terminal (wireless LAN terminal) is a wireless LAN access point (wireless AP). An example in which wireless LAN setting for wireless LAN connection is performed from a setting terminal (wireless LAN setting terminal) provided on the network to the wireless terminal MN will be described.

  The wireless terminal MN includes a plurality of wired and / or wireless communication interfaces including a wireless LAN interface compliant with the IEEE 802.11 standard.

The control unit 104 controls main operations of the wireless AP.

  FIG. 3 is a functional block diagram showing the configuration of the main part of the radio terminal MN, and again, the configuration unnecessary for the description of the present invention is omitted.

  The wireless LAN interface 201 transmits and receives wireless signals. The communication control unit 202 encrypts the wireless signal transmitted from the wireless LAN interface 201 and decrypts the wireless signal received by the wireless LAN interface 201. The UI unit 203 includes a touch switch (SW) 203a that accepts a user's operation and a display panel 203b. In the present embodiment, when an icon or switch displayed on the display panel 203b is touched, this is detected by the touch SW 203a. It is configured to be.

  The communication interface 205 transmits and receives wireless signals such as EV-DO and LTE. The communication control unit 206 encrypts the radio signal transmitted from the communication interface 205 and decrypts the radio signal received by the communication interface 205. The digital camera function unit 207 generates a camera image based on sensor information (here, an image signal) detected by an image sensor (not shown). Various programs and control data are stored in the ROM 208 in advance. The RAM 209 provides a work area to the control unit 204.

  FIG. 4 is a functional block diagram showing the configuration of the main part of the setting terminal, and again, the configuration unnecessary for the description of the present invention is omitted.

  The communication interface 301 transmits / receives data via a network. In the control unit 302, the character string recognition unit 302a recognizes the SSID and KEY character strings from the camera image received from the wireless terminal MN via the network. The profile generation unit 302b creates a file and software (hereinafter collectively referred to as “profile”) for setting the SSID and KEY in the wireless terminal MN. The profile response unit 302c responds to the generated profile to the wireless terminal MN that has transmitted the camera image.

  FIG. 5 is a sequence flow showing the operation of the first embodiment of the present invention. At time t1, the digital camera function unit 207 of the wireless terminal MN is activated in response to the operation of the terminal user. At time t2, a camera image is displayed on the display panel 203b. At times t3 and t4, wireless LAN setting information affixed to the housing of the wireless AP is taken and temporarily stored by the operation of the terminal user.

  At time t5, when the terminal user designates the address of the setting terminal and instructs transmission of the camera image, at time t6, the camera image is transmitted to the setting terminal. The wireless LAN setting information may be displayed as SSID and KEY character strings, or may be displayed by encoding these character strings into a one-dimensional code or a two-dimensional code.

At time t8, the profile generation unit 302b creates a profile for setting the recognized or decoded SSID and KEY in the wireless terminal MN. At time t9, the profile response unit 302c returns the created profile to the radio terminal MN.

  At time t10, the profile is received and installed by the wireless terminal MN, and wireless LAN setting information including the SSID and KEY is registered in a predetermined area of the RAM 209. Thereby, the wireless LAN setting is completed, and at time t11, a message indicating that the wireless LAN setting is completed is displayed on the display panel 203b to notify the user.

  In the above embodiment, the wireless LAN setting information has been described as image information such as SSID and KEY character strings, or code information obtained by encoding them, but the present invention is not limited to this. Rather, if the wireless AP or its installation environment is configured so that the SSID and KEY of the wireless AP can be modulated and output to a specific acoustic signal, the acoustic signal is detected and recorded by the wireless terminal MN with a microphone. While the sensor information is transmitted as wireless LAN setting information, the setting terminal may generate a profile by demodulating the SSID and KEY from the acquired sensor information (here, an acoustic signal).

  In this way, if wireless LAN setting information can be acquired as an acoustic signal, for example, even when a specific wireless LAN setting is required for each company conference room or school classroom, the wireless LAN setting information can be obtained wirelessly in the conference room or classroom. If an acoustic signal specific to the SSID and KEY of the AP is output each time and each wireless terminal transmits the acoustic signal to the setting terminal, the wireless LAN setting can be easily performed. At this time, if an acoustic signal outside the audible frequency band is used, the wireless LAN can be set while maintaining a substantially quiet environment.

  Similarly, if the wireless AP or its installation environment is configured so that the SSID and KEY of the wireless AP can be modulated and output to a specific optical signal (for example, infrared), this optical signal is detected by the wireless terminal MN as an optical sensor. Detecting and recording with, and transmitting this sensor information as wireless LAN setting information, while the setting terminal demodulates SSID and KEY from the acquired sensor information (here, optical signal) to generate a profile Also good.

  Further, in the case where the wireless LAN setting information is acquired as image information, in the above-described embodiment, the image information including the SSID and the KEY has been described. However, the present invention is not limited to this. If the wireless AP is a public wireless base station such as a Wi-Fi spot, shoot and send images that do not include SSID or KEY, such as scenery images and landmark images around the wireless AP installation location. You may do it.

  In this case, the correspondence between SSID and KEY and scenery images or landmark images (buildings, sculptures, paintings, etc.) around the location where the wireless AP is installed is registered in advance in the setting terminal. When the image is captured and transmitted to the setting terminal, the SSID and the KEY associated with the image or the image feature amount are searched, and a profile is generated and responded.

  In this way, for example, if you want to connect to a Wi-Fi spot near Tokyo Tower, take a picture of Tokyo Tower and send the camera image to the setting terminal. And KEY are searched and a profile is generated and responded.

  Furthermore, in the above embodiment, the wireless LAN setting information has been described as a set of SSID and KEY. However, there are different SSID and KEY pairs for each communication method (for example, the communication band is 2.4 GHz / 5.0 GHz). If acquired, all of them are transmitted as wireless LAN setting information. In the setting terminal, based on the model information of the wireless terminal MN received together with the plurality of SSID and KEY pairs, the wireless terminal MN Identify abilities.

  And if the wireless terminal MN supports only 2.4GHz wireless LAN channel, for example, it will generate a profile based on the 2.4GHz compatible SSID and KEY pair, while supporting both 2.4GHz and 5.0GHz If so, a profile may be generated based on a pair of SSID and KEY corresponding to 5.0 GHz. Alternatively, the setting terminal may generate profiles for 2.4 GHz and 5.0 GHz and respond both, and the wireless terminal MN may select one.

  In this way, if one of a plurality of SSID and KEY pairs is selected based on the model information of the wireless terminal MN and its profile is generated, the access point corresponding to 2.4 GHz is more mainstream. Radio interference is more likely to occur. On the other hand, 5GHz is a sidestream, so there is less radio interference. ”By responding with priority to the 5GHz profile, the wireless terminal MN that supports 5GHz A unique effect that interference can be avoided can be expected.

  According to the present embodiment, a wireless terminal MN as a set terminal is a general mobile phone such as a digital camera function, a function of transmitting a camera image, and a function of receiving a profile of wireless LAN setting information and installing it in itself. Wireless LAN settings can be easily and accurately set for the wireless terminal MN without requiring complicated operations for the terminal user, as long as it has the standard functions provided for phones, smartphones, and notebook PCs. Become.

  In addition, according to this embodiment, even if wireless LAN setting information unique to each wireless AP cannot be captured, wireless LAN settings can be performed by capturing and transmitting surrounding scenery images and landmark images. Therefore, the wireless LAN connection to the Wi-Fi spot where the display location of the wireless LAN setting information cannot be specified becomes easy.

[Second Embodiment]
In the first embodiment, the camera image of the wireless LAN setting information is transmitted from the wireless terminal MN to the setting terminal, and the character string of SSID and KEY is recognized in the setting terminal.

At time t1, the digital camera function unit 207 of the wireless terminal MN is activated in response to the operation of the terminal user. At time t2, a camera image is displayed on the display panel 203b. At times t3 and t4, the wireless LAN setting information affixed to the wireless AP casing or the like is photographed by the terminal user.

The

  At time t7, the correct SSID and KEY are selected by the user's operation from the SSID character string candidates and the KEY character string candidates. At time t8, the character string of the selected SSID and KEY is transmitted to the setting terminal by the character string transmission unit 204d as wireless LAN setting information.

  At time t9, a profile for setting the SSID and KEY in the wireless terminal MN is created in the setting terminal that has received the character string of the wireless LAN setting information. At time t10, the profile is returned to the wireless terminal MN.

When the wireless LAN setting is completed, at time t12, a message indicating that the wireless LAN setting is completed is displayed on the display panel 203b to notify the user.

  In the second embodiment described above, the character string candidates listed for each SSID and KEY have been described as being selected from the upper character strings based on the likelihood at the time of character recognition. The invention is not limited to this, and a character pair (for example, the number “9” and the alphabet “q”) that are likely to be misrecognized by experience is learned in advance and is irrelevant to the likelihood or the likelihood. In consideration of the degree, a plurality of character string candidates that are likely to be erroneously recognized as the most likely character string candidates in character recognition may be created based on the character pairs, and these may be displayed in a list.

  Furthermore, in the second embodiment described above, the SSID and KEY recognition are described as being performed in the wireless terminal MN. However, the present invention is not limited to this, and as in the first embodiment, the setting is performed. It may be performed on the terminal side. In this case, the setting terminal generates a profile including a plurality of character string candidates for each SSID and KEY and responds to the wireless terminal MN. The wireless terminal MN determines the character string candidates for the SSID and KEY included in the received profile. A list may be displayed to allow the user to select.

  According to the present embodiment, the processing for recognizing the SSID and KEY character strings from the camera image obtained by capturing the wireless LAN setting information is executed in each wireless terminal MN, so that the load related to character recognition is concentrated on the setting terminal. Instead, it is distributed to each wireless terminal MN. Therefore, even in a situation where it is necessary to perform wireless LAN setting intensively for a large number of wireless terminals MN, the setting terminal is not congested and each wireless LAN setting can be performed in a short time.
