Description

  The present invention relates to a wireless communication apparatus, a wireless setting method, and a wireless setting system, and more particularly, for a wireless terminal in which a wireless setting procedure is restricted to use setting information acquired from a specific wireless communication apparatus. The present invention relates to a wireless communication apparatus, a wireless setting method, and a system that can perform wireless setting with a simplified procedure.

  In recent years, wireless terminals represented by smartphones, portable game machines, digital photo frames, and the like are rapidly spreading. When using short-distance wireless communication such as wireless LAN with these wireless terminals, it is necessary to perform connection settings with a wireless access point (wireless AP) prepared in advance by the user. This connection setting is called wireless setting, and if it is wireless LAN setting, the following setting information is registered in the wireless LAN terminal.

(1) SSID (Service Set Identifier: ID that uniquely identifies an access point) held by a wireless AP
(2) Encryption method
(3) Encryption key / password (KEY)

  However, in order to set the setting information in the wireless terminal, wireless expertise is required, so that it is not an easy operation for an unfamiliar user.

  In response to such a technical problem, Non-Patent Document 1 discloses a technique for reducing the burden on the user by automating the setting operation. In Non-Patent Document 1, the wireless AP shifts to a mode (setting mode) that allows the wireless AP to establish a communication path with the wireless LAN terminal with temporary setting information by operating a button provided in the wireless AP. The wireless LAN terminal temporarily connects to the wireless AP using temporary setting information, and acquires normal setting information from the wireless AP using the wireless LAN communication path. Thereafter, the wireless LAN can be used (communication) by reconnecting to the wireless AP using the acquired normal setting information.

  FIG. 13 is a sequence flow showing the procedure of wireless LAN setting according to Non-Patent Document 1, and the first setting information for establishing a setting communication path for a set terminal (wireless LAN terminal) such as a smartphone. SSID1, KEY1, and encryption method common to all terminals are registered in advance. In a setting terminal such as a wireless AP, SSID2, KEY2, and an encryption method unique to each terminal are registered in advance as second setting information for establishing a normal communication path together with SSID1, KEY1, and an encryption method.

  In step S1, when the user presses a button provided in the setting terminal, the setting terminal is requested to start setting. Note that screen display or the like may be used instead of button operations. In the setting terminal where the button is operated, the operation mode is changed from “normal mode” to “setting mode”.

  In step S2, the user requests to start setting by operating the set terminal. For this request operation, a physical button, a software button, or the like can be used. In steps S3 and S4, SSID1 and KEY1 held in advance are set and registered in the terminal to be set. KEY1 is composed of a character string common to all setting terminals. In step S5, a temporary communication path for setting is established by the connected terminal temporarily connecting to the setting terminal using the SSID1 and KEY1.

  In step S6, a setting start instruction is transmitted from the set terminal to the setting terminal using the temporary communication path. In step S7, the setting terminal reads the MAC address of the terminal to be set in response to receiving the setting start instruction. In step S8, the setting information of SSID2 and KEY2 used in the normal mode is transmitted from the setting terminal to the set terminal. In step S9, reception confirmation data for notifying normal reception of the setting information is transmitted from the set terminal to the setting terminal.

  In step S10, in response to reception of reception confirmation data from the set terminal, the setting terminal registers the MAC address of the set terminal in the setting terminal itself. In step S11, terminal MAC address registration completion data for notifying the set terminal that the MAC address registration has been completed is transmitted from the setting terminal to the set terminal. In steps S12 and S13, in response to the reception of the terminal MAC address registration completion data in the set terminal, the settings of SSID2 and KEY2 acquired in step S8 are executed.

  On the other hand, Non-Patent Document 2 discloses a technique for setting restrictions on a wireless LAN setting method by a developer of a terminal to be set. In Non-Patent Document 2, setting information such as SSID and KEY required for wireless LAN settings is stored in a dedicated server on the network as a file (hereinafter referred to as a profile) described in a format uniquely defined by the developer. Has been. A user of the set terminal accesses the dedicated server from a Web browser and acquires a profile. In addition, a program for automatically installing the profile is installed in advance in the set terminal, and when the profile is acquired, the setting information is registered by starting the program and installing the profile. Is done.

  FIG. 14 is a sequence flow showing the procedure of wireless LAN setting according to Non-Patent Document 2, and wireless LAN setting information (SSID, KEY, and encryption method) is described in a setting terminal composed of a server and the like. A profile is held in advance.

  In step U1, setting information can be obtained by using a method such as notification by e-mail from a third party on the set terminal such as a smartphone or browsing the home page on which the user is connected to the Web server. URL, IP address, or link (hereinafter represented by URL) to the setting terminal that manages the profile including the URL is acquired.

  In step U2, a connection request is transmitted to the URL of the setting terminal in response to the user's operation at the set terminal. In step U3, the web page of the requested URL is returned from the setting terminal to the set terminal.

  In step U4, the set terminal receives the web page returned from the requested URL. At this time, the user can confirm that the web page is from a reliable setting terminal by confirming the content of the received web page. Therefore, it is possible to prevent the setting information of the setting terminal not intended by the user from being received, and security can be ensured.

  In step U5, connect to the URL where the profile containing the setting information of the wireless LAN access point is held by accessing the link destination for acquiring the setting information displayed on the display of the terminal to be set To do. In step U6, the setting terminal responds with the profile described in the wireless LAN setting information held in the requested URL. In step U7, the setting information of the wireless LAN is registered in the set terminal by installing the profile received from the setting terminal in the set terminal.

  Note that the difficulty of such wireless settings is due to the difficulty of inputting unique information such as IDs and passwords. Therefore, if the wireless connection requires input of unique information during wireless setting, the above wireless connection is not possible. The configuration is not limited to the LAN setting, and the same applies to the Bluetooth (registered trademark) setting, for example.

AOSS (Air Station One-Touch Secure System); (http://www.buffalotech.com/files/AOSS_WP_Final.pdf) iPhone configuration profile; (http://developer.apple.com/devcenter/ios/library/documentation/FA_iPhone_Configuration_Utility.pdf)

  If the technique disclosed in Non-Patent Document 1 is used, the operation of wireless LAN setting can be simplified, but it is not sufficient. In addition, for a set terminal in which the wireless LAN setting method is restricted by the technique of Non-Patent Document 2, the technique disclosed in Non-Patent Document 1 is applied to simplify the operation of the wireless LAN setting.

  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 the present invention is applied. Here, a wireless terminal MN as a set terminal is a wireless for wireless LAN connection to a wireless LAN access point (wireless AP). The LAN setting will be described as an example, but the present invention can be similarly applied to the case where Bluetooth (registered trademark) setting is performed on a Bluetooth (registered trademark) wireless terminal.

  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 wireless AP stores wireless LAN setting information including a network name (SSID) and an encryption key (KEY) for wireless LAN connection, and a sticker on which the wireless LAN setting information is printed is a housing of the wireless AP, It is affixed to an appropriate place such as an instruction manual, warranty card or a wall in the living room where the wireless AP is installed.

[First embodiment]
FIG. 2 is a functional block diagram showing the configuration of the main part of the wireless AP. In general, a wireless AP establishes a wireless connection with a wireless terminal and functions as a wireless communication apparatus for performing wireless communication, and also functions for relaying communication between wireless terminals, and for connecting wireless terminals to other networks. Various functions such as a function of connecting to a wireless communication device are described here, but here, description will be given focusing on the function as a wireless communication device necessary for the description of the present invention.

  The wireless LAN interface 101 transmits and receives wireless signals. The communication control unit 102 encrypts the wireless signal transmitted from the wireless LAN interface 101 and decrypts the wireless signal received by the wireless LAN interface 101. In the memory area 103, the wireless LAN setting information holding unit 103a holds a network name SSID, an encryption key KEY, and an encryption method specific to the wireless AP as wireless LAN setting information in advance. 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 illustrations of components unnecessary for the description of the present invention are 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. Here, the configuration unnecessary for the description of the present invention is also omitted.

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

  When the terminal user instructs transmission of the camera image at time t5, the camera image is transmitted to the setting terminal at time t6. 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 t7, the character string recognition unit 302a of the setting terminal recognizes or decodes the character strings of SSID and KEY from the camera image of the wireless LAN setting information received from the wireless terminal MN. At time t8, the setting file generating unit 302b generates a setting file for setting the recognized or decrypted SSID and KEY in the wireless terminal MN. At time t9, the created setting file is returned to the wireless terminal MN by the setting file response unit 302c.

  At time t10, the setting file is received 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. After that, as in the general wireless connection procedure, the setting information is authenticated and responded between the wireless terminal MN and the wireless AP, and a completion notification is output when the wireless LAN setting is completed. For example, in the case of the wireless terminal MN, at time t11, a message indicating that the wireless LAN setting is completed is displayed on the display panel 203b and notified to 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 the setting file by demodulating the SSID and KEY from the acquired sensor information (in this case, 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, the wireless AP modulates the SSID and KEY into a signal corresponding to the content, for example, a time-series signal, and converts this to an optical signal that can be detected by the optical sensor of the wireless terminal MN at the start timing of the wireless setting. And may be configured to output. The wireless terminal MN detects and records this optical signal with an optical sensor, and transmits this sensor information as wireless LAN setting information. On the setting terminal, the SSID and the SSID and the acquired sensor information (here, the optical signal) are transmitted. The configuration file may be generated by demodulating the KEY.

  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 taken and transmitted to the setting terminal, the setting file is generated and responded by searching for the SSID and KEY associated with the image or the image feature amount.

  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 configuration file 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.

  If the wireless terminal MN supports only 2.4 GHz wireless LAN channels, for example, it generates a configuration file based on the SSID and KEY pair that supports 2.4 GHz, while both 2.4 GHz and 5.0 GHz If it is compatible, the configuration file may be generated based on an SSID / KEY pair compatible with 5.0 GHz. Alternatively, the setting terminal may generate a setting file for 2.4 GHz and 5.0 GHz and respond both, and the wireless terminal MN may select one of them.

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

  According to the present embodiment, a general mobile phone such as a wireless terminal MN as a set terminal has a digital camera function, a function of transmitting a camera image, and a function of receiving wireless LAN setting information and performing wireless settings. If a smartphone or notebook PC is equipped with the standard functions, wireless LAN settings can be easily and accurately set for the wireless terminal MN without requiring complicated operations from the terminal user. .

  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. However, these processes may be performed on the wireless terminal MN side.

  FIG. 6 is a functional block diagram showing the configuration of the main part of the radio terminal MN according to the second embodiment of the present invention. The same reference numerals as those described above represent the same or equivalent parts, and the description thereof is omitted. To do.

  In the control unit 204, the character string recognition unit 204a recognizes the SSID and KEY character strings from the camera image of the wireless LAN setting information photographed by the digital camera function unit 207. As shown in an example in FIG. 7, the character string candidate output unit 204b displays a list of the top N best vests of the SSID and KEY recognition results on the display panel 203b as character string candidates.

  The character string determination unit 204c determines one SSID and KEY designated by the user's input operation as a character string of the wireless LAN setting information. Here, “abcde” is selected as the SSID, and “1234” is selected as the KEY. The character string transmission unit 204d transmits the selected character string to the setting device.

  FIG. 8 is a sequence flow showing the operation of the second 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, the wireless LAN setting information affixed to the wireless AP casing or the like is photographed by the terminal user.

  At time t5, the character string recognition unit 204a recognizes the SSID and KEY character strings from the camera image of the wireless LAN setting information. At time t6, as shown in FIG. 7, the character string candidate output unit 204b outputs the top N best with the highest likelihood among the SSID and KEY recognition results to the display panel 203b as character string candidates. 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 setting file 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 setting file is returned to the wireless terminal MN.

  At time t11, the setting file is received 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. 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 setting file including a plurality of character string candidates for each SSID and KEY and responds to the wireless terminal MN. In the wireless terminal MN, the SSID and KEY character strings included in the received setting file A list of candidates 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.

[Third embodiment]
