A-3. Schematic configuration of terminal:
FIG. 3 is a block diagram functionally showing the configuration of the terminal 30. The terminal 30 includes a CPU 310, a ROM 320, a RAM 330, a wireless communication interface (I / F) 340, a mobile communication network communication interface (I / F) 350, a touch panel 360, and a voice communication unit 370. Each component is mutually connected by a bus.

  The CPU 310 controls the terminal 30 by developing a computer program stored in the ROM 320 on the RAM 330 and executing it. Further, the CPU 310 realizes the functions of the WEB browser 311 and the STA side connection control unit 312.

  The WEB browser 311 is a computer program used for browsing content acquired from the WWW (World Wide Web) based on, for example, a data transfer protocol such as HTTP (HyperText Transfer Protocol). As the data transfer protocol, any protocol may be used as long as it is a client server type protocol that can transmit and receive information by using a loopback address in a communication protocol such as TCP / IP. For example, HTTP, HTTPS (Secure HyperText Transfer Protocol), etc. can be used. Moreover, HTTP and HTTPS are merely examples, and are not limited to these protocols. The WEB browser 311 is used for displaying guidance received by the terminal 30 from the AP 10 in the duplication processing.

  The STA side connection control unit 312 controls connection of wireless communication based on IEEE 802.11 via the wireless communication interface 340. The STA side connection control unit 312 establishes the first wireless communication C1 (FIG. 1) by connecting a wireless connection device such as the AP 10 to the terminal 30 as a wireless communication access point. In this case, the terminal 30 operates as a client of the first wireless communication C1. The STA side connection control unit 312 functions as a “slave device connection control unit”.

  The wireless communication interface 340 includes a transmission / reception circuit (not shown), and has a function of demodulating a radio wave received via an antenna and generating data, and generating and modulating a radio wave transmitted via the antenna. The mobile communication network communication interface 350 includes an antenna and a transmission / reception circuit (not shown). For example, the mobile communication network communication interface 350 performs data communication and voice communication with a communication carrier by a mobile communication system compliant with WiMAX / 3G / LTE. .

  The touch panel 360 has a structure in which a display device such as a liquid crystal screen and an input information acquisition device such as a colorless and transparent touch pad are stacked. When the user of the terminal 30 presses a graphical user interface (GUI) such as an icon displayed on the liquid crystal screen with a finger, the touchpad detects an input (for example, a press) to a position where the icon is displayed. Then, an electrical signal representing the detected position is transmitted to the CPU 310. In the present embodiment, the touch panel 360 functions as a “display unit”.

  Audio communication unit 370 includes a speaker for outputting audio, a microphone for inputting audio, a circuit for driving these, and the like. The terminal 30 also operates as a telephone by including the mobile communication network communication interface 350 and the voice communication unit 370.

A-4. Replication process:
Hereinafter, a procedure of replication processing using the AP 10 of this embodiment will be described. There are the following two types of replication processing that can be executed by the AP 10 of the present embodiment.
-Duplication processing using AOSS-Duplication processing using WPS Which duplication processing is executed is determined by the configuration of the existing AP 20. When the AP 20 supports both AOSS and WPS, in other words, when the AP 20 includes both the AP-side AOSS processing unit 212 and the AP-side WPS processing unit 213, replication processing using AOSS Is executed with priority. On the other hand, when the AP 20 supports only WPS, in other words, when the AP 20 includes only the AP-side WPS processing unit 213, replication processing using WPS is executed. Even when the AP 20 includes both the AP-side AOSS processing unit 212 and the AP-side WPS processing unit 213, the content of the security setting of the AP 20, such as the presence / absence of an authentication / encryption method in wireless communication, Depending on the type, a replication process using WPS may be executed instead of the replication process using AOSS. Specifically, for example, when there is no authentication / encryption method in wireless communication, in other words, when the authentication / encryption method is OPEN setting, a replication process using WPS may be executed. Further, when the authentication / encryption method in wireless communication is WPA2-EAP (Wi-Fi Protected Access 2 Extensible Authentication Protocol) setting, a replication process using AOSS may be executed.

A-4-1. Duplication processing using AOSS:
FIG. 4 is a sequence diagram showing the procedure of the replication process using AOSS. In step S102, the user presses the setting button 120 of the new AP 10.

  In step S104, the AP 10 that has detected that the setting button 120 has been pressed for a time exceeding a predetermined threshold value is activated as an AP (Access Point), and induces a connection from the terminal 30 to the AP 10. Specifically, the AP 10 activates the AP 10 in the AP mode by activating the AP-side connection control unit 114x. Thereafter, the AP side connection control unit 114x transmits a special beacon. In the present embodiment, based on the setting information stored in the preset setting information 161, a beacon including an SSID prefixed with the character “!” Is used as a special beacon. On the wireless network connection screen of the terminal 30, a list of APs that transmitted beacons received by the terminal 30 is displayed. This list is usually displayed in ascending order of SSID (in order of increasing SSID character code). Therefore, if the top of the SSID is “!”, The AP can be expected to be displayed at or near the top of the list of SSIDs displayed on the wireless network connection screen of the terminal 30. For this reason, the user of the terminal 30 can easily find the AP 10 on the wireless network connection screen. As a result, the AP side connection control unit 114x can guide the connection from the terminal 30 to the AP 10.

  In step S106, the terminal 30 discovers and connects to the AP 10 that emits a special beacon. Specifically, the terminal 30 generates the above-described wireless network connection screen based on the beacon received by the terminal 30 and causes the touch panel 360 to display the wireless network connection screen. The user selects the AP 10 displayed at or near the top of the wireless network connection screen. The STA side connection control unit 312 of the terminal 30 transmits a connection request specifying the SSID (special SSID starting with “!”) Selected by the user to the AP 10. The AP-side connection control unit 114x of the AP 10 that has received the connection request from the terminal 30 makes a “first” with the terminal 30 based on the special SSID setting information starting from “!” Preset in the AP 10. Wireless communication ".

  In this manner, the AP side connection control unit 114x (first connection control unit) of the AP 10 guides the connection to the first wireless communication by the terminal 30 (wireless terminal). For this reason, establishment of the 1st wireless communication between AP10 (wireless connection apparatus) and the terminal 30 can be made easy.

  In step S <b> 108, the user accesses an arbitrary WEB page using the WEB browser 311 of the terminal 30. In step S110, the WEB browser 311 of the terminal 30 transmits an Internet connection request to the AP 10 in order to acquire the WEB page received from the user.

  In step S112, the guide unit 116 of the AP 10 replaces the address of the Internet connection request received from the terminal 30. Specifically, the guide unit 116 responds to the inquiry of the DNS (Domain Name System) address of the Internet connection request with the address of the WEB page in order to display the guide by the guide unit 116.

  In step S <b> 114, the guide unit 116 of the AP 10 transmits the content of the WEB page for displaying the guide 1 to the terminal 30. Here, the guide 1 is a guide for confirming with the user whether or not to start copying of setting information regarding wireless communication from the AP 20 to the AP 10. In step S116, the WEB browser 311 of the terminal 30 displays the received guidance 1 on the touch panel 360.

  FIG. 5 is an example of a guide 1 screen. On the screen W1 of the guidance 1, a message MG1 asking whether or not to start copying of setting information related to wireless communication, a No button B11, and a Yes button B12 are arranged.

  In step S118 of FIG. 4, the user presses the yes button B12 on the screen W1. In step S120, the WEB browser 311 of the terminal 30 that has detected the pressing of the Yes button B12 transmits a copy start request to the AP 10. Note that when the pressing of the No button B11 is detected, the WEB browser 311 of the terminal 30 transmits an end request for the replication process (FIG. 4) to the AP 10. The AP 10 that has received the termination request terminates the processing of FIG.

  In step S122, the AP 10 starts operating as an AOSS client. Specifically, the AP 10 activates the STA side connection control unit 114y to activate the AP 10 in the STA (Station) mode. In addition, the AP 10 can realize the AOSS function by activating the STA side AOSS processing unit 112. Thereafter, the STA-side connection control unit 114y of the AP 10 performs an AP (Access Point) scan. AP scan is the name of an operation for detecting an access point existing within the radio wave reachable range. Note that the number of AP scan executions in the present embodiment may be one or more.

  In step S <b> 124, the guide unit 116 of the AP 10 transmits the content of the WEB page for displaying the guide 2 to the terminal 30. Here, the guidance 2 is guidance for prompting the user to press the setting button 220 of the AP 20 in order to start the AOSS function of the existing AP 20. In step S <b> 126, the WEB browser 311 of the terminal 30 displays the received guidance 2 on the touch panel 360.

  FIG. 6 is an example of a guide 2 screen. A message MG2 that prompts the user to press the setting button 220 of the AP 20 is disposed on the screen W2 of the guidance 2.

  In step S128 of FIG. 4, the user presses the setting button 220 of the AP 20 in accordance with the message MG2 on the screen W2.

  In step S130, the AP 20 that has detected the pressing of the setting button 220 starts an operation as an AOSS access point. Specifically, the AP 20 activates the AP side connection control unit 214 to activate the AP 20 in the AP mode. Further, the AP 20 enables the AOSS function by activating the AP-side AOSS processing unit 212.

  In step S132, the STA side connection control unit 114y of the AP 10 repeatedly performs the AP scan and detects the AP 20 activated in the AP mode. Thereafter, the STA side connection control unit 114y performs AOSS connection to the detected AP 20 using an arbitrary frequency band. As a result, the “second wireless communication” that is the temporary communication described in the above-described process a1 is established between the AP 10 and the AP 20.

  In step S <b> 134, the guidance unit 116 of the AP 10 transmits the content of the WEB page for displaying the guidance 3 to the terminal 30. Here, the guide 3 is a guide for notifying that setting information relating to wireless communication from the existing AP 20 to the new AP 10 is being copied (that is, moving from the AP 20 to the AP 10). In step S136, the WEB browser 311 of the terminal 30 displays the received guidance 3 on the touch panel 360.

  FIG. 7 is an example of a guide 3 screen. On the screen W3 of the guidance 3, a message MG31 indicating that setting information relating to wireless communication from the AP 20 to the AP 10 is being copied, and a progress bar MG32 indicating the progress of copying the setting information are arranged.

  In step S138 of FIG. 4, the AP-side AOSS processing unit 212 of the AP 20 transmits setting information related to wireless communication in all frequency bands supported by the AP 20 to the AP 10. The transmission of information in step S138 is performed using the AOSS function described in the above process a2.

  In step S140, the STA-side AOSS processing unit 112 of the AP 10 acquires setting information related to wireless communication from the AP 20. The STA side AOSS processing unit 112 stores the acquired setting information related to wireless communication in the setting information storage area 162. The STA side AOSS processing unit 112 causes the STA side connection control unit 114y to disconnect the temporary communication (second wireless communication) established with the AP 20, and then ends the process.

  In step S142, the AP-side AOSS processing unit 212 of the AP 20 causes the AP-side connection control unit 214 to disconnect the temporary communication (second wireless communication) established with the AP 10, and then ends the processing.

  In step S144, the guide unit 116 of the AP 10 transmits the content of the WEB page for displaying the guide 4 to the terminal 30. Here, the guide 4 is a guide for notifying that the copying of the setting information regarding the wireless communication from the existing AP 20 to the new AP 10 has ended (that is, the moving from the AP 20 to the AP 10 has ended). In step S146, the WEB browser 311 of the terminal 30 displays the received guidance 4 on the touch panel 360.

  FIG. 8 is an example of a screen for the guide 4. On the screen W4 of the guidance 4, there are a message MG4 indicating that copying of setting information related to wireless communication from the AP 20 to the AP 10 has ended, items L41 and L42 indicating the contents of the copied setting information, and an end button B4. Has been placed. In the example of FIG. 8, the message MG4 includes guidance for instructing the user to turn off the power of the existing AP 20 (old AP), along with guidance on the end of copying. In addition, in the item L41, setting information of the first frequency band among the setting information related to wireless communication copied from the AP 20 to the AP 10 is displayed. Similarly, in the item L42, setting information of the second frequency band among the setting information related to wireless communication copied from the AP 20 to the AP 10 is displayed.

  In step S148 of FIG. 4, the user presses the end button B4 on the screen W4. In step S150, the terminal 30 that has detected the pressing of the end button B4 transmits a copy processing end request to the AP 10. In step S152, the user turns off the existing AP 20 according to the message MG4 on the screen W4. Thereby, the 2nd radio | wireless communication between AP10 and AP20 is cut | disconnected.

  In step S154, the AP 10 terminates the STA mode of the AP 10 by terminating the processing of the STA side connection control unit 114y. Similarly, the AP 10 ends the AP mode of the AP 10 by terminating the process of the AP side connection control unit 114x. Thereby, the first wireless communication between the AP 10 and the terminal 30 is disconnected.

  In step S156, the AP 10 starts up in the AP mode to which the setting information in the setting information storage area 162 is applied. Specifically, the AP 10 activates the AP 10 in the AP mode by activating the AP-side connection control unit 114x. Also, as the information used for the processing of the AP side connection control unit 114x, the setting information stored in the setting information storage area 162, that is, the setting information related to wireless communication in all frequency bands supported by the AP 20 is applied. To do.

  As described above, in the replication processing using AOSS, the STA side AOSS processing unit 112 (acquisition unit) of the new AP 10 relates to wireless communication in all frequency bands supported by the existing AP 20 (other wireless connection devices). Since the setting information is acquired at a time, the setting information set in the AP 20 can be acquired quickly.

  In the duplication processing using AOSS, the guide unit 116 may guide the user to that effect when the duplication processing fails. The failure in executing the duplication processing occurs due to, for example, a failure in connection from the AP 10 to the AP 20 (step S132), a failure in obtaining setting information regarding wireless communication from the AP 20 (step S138), or the like. Guidance on the failure to execute the replication process can be performed using the guidance 5.

  FIG. 9 is an example of a screen for the guide 5. On the screen W5 of the guidance 5, a message MG5 indicating that the duplication processing has failed, a retry button B51, a detail button B52, and an end button B53 are arranged. Upon detecting that the retry button B51 is pressed, the AP 10 starts the process of FIG. 4 from the beginning (or step S104). Upon detection of pressing of the detail button B52, the AP 10 transmits a WEB page for displaying detailed information regarding the processing in FIG. The detailed information is, for example, contents of the AP 10 system log, error log, and the like. Upon detection of pressing of the end button B53, the AP 10 ends the process of FIG.

A-4-2. Copy processing using WPS:
FIG. 10 is a sequence diagram showing a procedure of a replication process using WPS. The difference from the replication processing using AOSS shown in FIG. 4 is that steps S202 to S236 are provided instead of steps S122, S130, S132, S138, S140, and S142. Hereinafter, processes having the same step numbers as in FIG. 4 will be described with the contents omitted, but the details are the same as those in FIG. Note that the example shown in FIG. 10 is a processing flow when only setting information corresponding to one frequency band can be transmitted in the processing a2 of the WPS function.

  In step S102, the user presses the setting button 120 of the new AP 10 for a time exceeding a predetermined threshold. In step S104, the AP 10 starts up as an AP and induces a connection from the terminal 30 to the AP 10. In step S106, the terminal 30 connects to the AP 10. In step S108, the user accesses an arbitrary WEB page. In step S110, the WEB browser 311 of the terminal 30 transmits an Internet connection request to the AP 10. In steps S112 to S116, the guidance unit 116 of the AP 10 replaces the address of the Internet connection request received from the terminal 30, and displays guidance 1 (FIG. 5) on the terminal 30. In step S118, the user presses the Yes button B12 on the screen W1. In step S120, the WEB browser 311 of the terminal 30 that has detected the pressing of the Yes button B12 transmits a copy start request to the AP 10.

  In step S202, the AP 10 starts operating as a WPS client. Specifically, the AP 10 activates the STA side connection control unit 114y to activate the AP 10 in the STA mode. Further, the AP 10 enables the WPS function by activating the STA side WPS processing unit 113. Thereafter, the STA side connection control unit 114y performs an AP scan. In steps S124 and S126, the guidance unit 116 of the AP 10 displays guidance 2 (FIG. 6) on the terminal 30. In step S128, the user presses the setting button 220 of the AP 20.

  In step S204, the AP 20 that has detected the pressing of the setting button 220 starts operation as a WPS access point and registrar. Specifically, the AP 20 activates the AP side connection control unit 214 to activate the AP 20 in the AP mode. In addition, the AP 20 enables the WPS function by activating the AP-side WPS processing unit 213.

  In step S206, the STA side connection control unit 114y of the AP 10 repeatedly performs the AP scan, and detects the AP 20 activated in the AP mode. Thereafter, the detection unit 115 of the AP 10 starts detecting the frequency band to which the detected AP 20 corresponds.

  FIG. 11 is an explanatory diagram for describing a method of detecting a corresponding frequency band of the AP 20. FIG. 11A shows AP10 and AP20 at time t1 after the start of detection of the corresponding frequency band of AP20. At time t1, the detection unit 115 of the AP 10 attempts to receive a beacon transmitted from the AP 20 using the first frequency band (for example, 2.4 GHz) supported by the wireless communication interface 140 of the AP 10. (FIG. 11 (A)). When detecting the beacon in the first frequency band, the detection unit 115 acquires a UUID (Universally Unique IDentifier) included in the beacon and stores the acquired UUID in the flash ROM 160. The UUID is a unique identifier used for specifying that the beacon transmission source is the AP 20.

  On the other hand, when the detection unit 115 cannot receive the beacon in the first frequency band, the detection process in FIG. 11 is terminated, and the process proceeds to step S154 in the duplication process in FIG.

  FIG. 11B shows AP10 and AP20 at time t2 after time t1. At time t2, the detection unit 115 of the AP 10 is transmitted from the AP 20 using a second frequency band (for example, 5 GHz) different from the first frequency band supported by the wireless communication interface 140 of the AP 10. Trying to receive a beacon (FIG. 11B). When detecting the beacon in the second frequency band, the detection unit 115 acquires the UUID included in the beacon. The detection unit 115 compares the acquired UUID with the UUID stored in the flash ROM 160 at time t1, and determines whether the UUID matches. When the UUIDs match, the detection unit 115 corresponds to the first frequency band (2.4 GHz) detected at time t1 and the second frequency band (5 GHz) detected at time t2. Is identified.

  On the other hand, when the detection unit 115 cannot receive the beacon of the second frequency band or the UUID does not match, the detection unit 115 sets the corresponding frequency band of the AP 20 to the first frequency band (2 .4 GHz).

  When the wireless communication interface 140 of the AP 10 supports three or more frequency bands, the detection unit 115 of the AP 10 repeatedly executes the same processing at time t2 for all the corresponding frequency bands, The corresponding frequency band of the AP 20 is detected.

  Thus, the detection unit 115 of the AP 10 can detect the frequency band supported by the AP 20 based on the beacon transmitted from the AP 20 (other wireless connection device). As a result, in the subsequent duplication processing, the STA side WPS processing unit 113 can sequentially try to obtain setting information related to wireless communication for the frequency band detected by the detection unit 115.

  In step S208 of FIG. 10, the STA side connection control unit 114y performs WPS connection to the AP 20 using the first frequency band detected in step S206. As a result, using the first frequency band between the AP 10 and the AP 20, “second wireless communication”, which is temporary communication similar to the above-described process a1, is established. In steps S134 and S136, the guide unit 116 of the AP 10 displays the guidance 3 (FIG. 7) on the terminal 30.

  In step S210, the AP-side WPS processing unit 213 of the AP 20 transmits setting information related to radio communication in the frequency band used for temporary communication, that is, the first frequency band, to the AP 10. The information transmission in step S210 is performed using the same WPS function as in the above-described process a2.

  In step S212, the STA side WPS processing unit 113 of the AP 10 acquires setting information related to wireless communication from the AP 20. The STA side WPS processing unit 113 stores the acquired setting information related to wireless communication in the setting information storage area 162. The STA side WPS processing unit 113 terminates the processing after causing the STA side connection control unit 114y to disconnect the temporary communication (second wireless communication) established with the AP 20.

  In step S214, the AP side WPS processing unit 213 of the AP 20 causes the AP side connection control unit 214 to disconnect the temporary communication (second wireless communication) established with the AP 10, and then ends the processing.

  Note that, in the process a2 of the WPS function, when the AP 20 can transmit setting information corresponding to all frequency bands, in step S212, the STA side WPS processing unit 113 sets setting information related to wireless communication corresponding to all frequency bands. Can be acquired. In this case, the STA side WPS processing unit 113 saves the acquired setting information related to wireless communication in the setting information storage area 162, and then shifts the process to step S144. As a result, after the guidance 4 is displayed, the STA mode of the AP 10 ends, and the AP 10 starts up in the AP mode to which the setting information in the setting information storage area 162 is applied.

  In step S216, the STA side WPS processing unit 113 of the AP 10 starts the WPS function again. Thereafter, the STA side connection control unit 114y performs an AP scan.

  In step S218, the guide unit 116 of the AP 10 transmits the content of the WEB page for displaying the guide 6 to the terminal 30. Here, the guidance 6 is guidance for prompting the user to press the setting button 220 of the AP 20 again in order to restart the WPS of the existing AP 20. In step S220, the WEB browser 311 of the terminal 30 displays the received guidance 6 on the touch panel 360.

  FIG. 12 is an example of a screen for the guide 6. On the screen W6 of the guidance 6, a message MG61 indicating that replication of setting information related to wireless communication from the AP 20 to the AP 10 has been completed, an item L61 indicating the content of the copied setting information, and a pressing of the setting button 220 of the AP 20 A message MG62 for prompting is placed. In the example of FIG. 12, the setting information of the first frequency band among the setting information related to wireless communication copied from the AP 20 to the AP 10 is displayed in the item L61. By confirming the item L61, the user can know that only a part of the setting information related to the wireless communication of the AP 10 has been copied.

  In step S222 of FIG. 10, the user presses the setting button 220 of the AP 20 according to the message MG62 on the screen W6.

  In step S224, the AP 20 that has detected the pressing of the setting button 220 starts operation as a WPS access point and registrar. Details are the same as in step S204.

  In step S226, the STA side connection control unit 114y of the AP 10 repeatedly performs the AP scan, and detects the AP 20 activated in the AP mode. Thereafter, the STA-side connection control unit 114y determines, for the AP 20, a frequency band different from the frequency band used for the WPS connection in step S208 among the corresponding frequency bands of the AP 20 detected in step S206 (that is, the second frequency band). The WPS connection is performed using the frequency band. As a result, the temporary communication (second wireless communication) similar to the above-described process a1 is established between the AP 10 and the AP 20 using the second frequency band. In steps S228 and S230, the guidance unit 116 of the AP 10 displays guidance 3 (FIG. 7) on the terminal 30.

  In step S232, the AP-side WPS processing unit 213 of the AP 20 transmits setting information related to radio communication in the frequency band used for temporary communication, that is, the second frequency band, to the AP 10. The information transmission in step S232 is performed using the same WPS function as in the above-described process a2.

  In step S234, the STA side WPS processing unit 113 of the AP 10 acquires setting information related to wireless communication from the AP 20. The STA side WPS processing unit 113 stores the acquired setting information related to wireless communication in the setting information storage area 162 separately from the setting information of the first frequency band acquired in step S212. The STA side WPS processing unit 113 terminates the processing after causing the STA side connection control unit 114y to disconnect the temporary communication (second wireless communication) established with the AP 20.

  When there are three or more corresponding frequency bands of the AP 20 detected in step S206, the above-described steps S216 to S234 are repeatedly executed until the AP 10 acquires setting information related to wireless communication in all frequency bands. As a result, if there are N corresponding frequency bands of the AP 20 detected in step S206, the processes in steps S216 to S234 are repeated (N-1) times.

  After acquiring the setting information of all frequency bands, the AP-side WPS processing unit 213 of the AP 20 in step S236 sends the temporary communication established with the AP 10 to the AP-side connection control unit 214 (second wireless communication). After cutting, the process is terminated.

  In steps S144 and S146, the guide unit 116 of the AP 10 displays the guide 4 (FIG. 8) on the terminal 30. In steps S148 and S150, the terminal 30 transmits a copy processing end request to the AP 10. In step S152, the user turns off the existing AP 20 according to the message MG4 on the screen W4. In step S154, the AP 10 ends the STA mode of the AP 10 and the AP mode of the AP 10. Thereby, the first wireless communication between the AP 10 and the terminal 30 is disconnected. In step S156, the AP 10 starts up in the AP mode to which the setting information in the setting information storage area 162 is applied.

  As described above, in the replication processing using WPS, the STA side WPS processing unit 113 (acquisition unit) of the new AP 10 relates to wireless communication in a plurality of frequency bands supported by the existing AP 20 (other wireless connection devices). The setting information is sequentially acquired, such as setting information of the first frequency band, setting information of the second frequency band. For this reason, the setting information set in the AP 20 can be obtained by being divided for each corresponding frequency band of the AP 20.

  Further, according to steps S208 and S226 of the replication process using WPS, the STA side connection control unit 114y (connection control unit) determines that the new AP 10 (wireless connection device) is compared with the existing AP 20 (other wireless connection devices). When the WPS connection is established, the STA side WPS processing unit 113 (acquisition unit) connects using the frequency band for which setting information related to wireless communication is to be acquired. For this reason, the STA side WPS processing unit 113 can easily acquire setting information related to wireless communication using a method (WPS function) provided by the AP 20.

  Further, according to steps S218 and S220 (guidance 6) of replication processing using WPS, the guide unit 116 of the new AP 10 is set for wireless communication in one frequency band (the first frequency band in the example of FIG. 10). After the acquisition of information is completed, if there is setting information that has not yet been acquired among the setting information related to wireless communication in a plurality of frequency bands supported by the existing AP 20 (another wireless connection device). Can be guided to the user. As a result, usability for the user can be improved. Also, the configuration information that sequentially acquires setting information related to wireless communication for a plurality of frequency bands supported by the AP 20, in other words, the configuration that realizes replication processing using WPS, suppresses occurrence of setting information acquisition omissions. can do.

  As described above, after the replication process using AOSS (FIG. 4) or the replication process using WPS (FIG. 10) is completed, the configuration of the network system 1 is changed to the configuration shown in FIG. Thus, wireless communication between the terminal 30 used by the user and the new AP 10 becomes possible.

  Note that, after the replication process using AOSS (FIG. 4) or the replication process using WPS (FIG. 10) is completed, at least one of the new AP 10 and the existing AP 20 will be described below. Any one of b1 to b8 may be executed. Note that the processes b1 to b7 may be executed in combination.

(B1) The AP is automatically turned off.
(B2) The beacon transmission is stopped until the power of the AP is turned off.
(B3) Until the power of the AP is turned off, processing based on an inquiry (probe request or the like) from another AP or wireless terminal is stopped.
(B4) Until the power of the AP is turned off, processing based on connection requests (association requests, authentication requests) from other APs and wireless terminals is stopped.
(B5) On the touch panel 360 of the terminal 30, a warning that there are a plurality of APs operating based on the same setting related to wireless communication is displayed.
(B6) Using a display device such as an AP indicator or a liquid crystal screen, a warning that there are a plurality of APs operating based on the same wireless communication setting is displayed.
(B7) A warning message to the effect that there are a plurality of APs operating based on the same wireless communication settings is sent to a mail address registered in advance for the AP.
(B8) When an AP scan is performed and another AP transmitting a beacon having the same SSID as itself is detected, one of the above-described processes b1 to b7 is executed.

  As described above, according to the processing b1 to b8, the occurrence of a problem due to the presence of two access points (specifically, AP10 and AP20) having setting information related to the same wireless communication in the network system 1. Can be avoided.

Further, after the replication process using AOSS (FIG. 4) or the replication process using WPS (FIG. 10) is completed, any one of the processes c1 to c3 described below is performed on the new AP 10. It may be executed.
(C1) When the AP 10 determines that the content of the security setting of the existing AP 20 (for example, the presence / absence or type of an authentication / encryption method in wireless communication) is lower than a certain security level, the setting information storage area 162 The setting information related to wireless communication stored in is not validated until an instruction is received from the user. The instruction from the user may be given through the setting screen of the AP 10 provided by means such as HTTP (HyperText Transfer Protocol). In this way, the user of the AP 10 can validate the setting information after confirming the security level of the setting information regarding the wireless communication copied from the existing AP 20.
(C2) Even if it is determined that the content of the security setting of the existing AP 20 (for example, the presence / absence or type of authentication / encryption method in wireless communication) is lower than a certain security level, the network system 1 If the type of authentication / encryption scheme that can be handled by the wireless terminal to which the terminal belongs (for example, the terminal 30) does not reach the above-mentioned “certain security level”, the AP 10 can set the setting information storage area without depending on an instruction from the user The setting information related to wireless communication stored in 162 may be immediately effective.
(C3) In step S140 of FIG. 4 or steps S212 and S234 of FIG. 10, the AP 10 stores the contents of the security settings of the existing AP 20 (for example, the presence / absence or type of authentication / encryption method in wireless communication). When it is determined that the security level is lower than a certain security level, saving the setting information related to the wireless communication in the setting information storage area 162 may be omitted.

  As described above, according to the processes c1 to c3, the AP 10 performs at least one of storage of the acquired setting information and activation using the acquired setting information according to the setting content related to the security of the AP 20. Either one can be omitted. For this reason, when the security of AP20 is low, it can suppress that the setting information of the said AP20 is applied to AP10 as it is.

  As described above, according to the first embodiment, the STA-side AOSS processing unit 112 or the STA-side WPS processing unit 113 (acquisition unit) of the AP 10 (wireless connection device) can connect the new AP 10 and the existing AP 20 (other wireless connection). The setting information regarding the wireless communication set in the AP 20 is acquired via the second wireless communication C2 with the device. In addition, the guide unit 116 of the AP 10 transmits guidance (guidance 1 to 6) to the terminal 30 via the first wireless communication C1 between the AP 10 and the terminal 30 (wireless terminal). The acquired setting information of the AP 20 is stored separately from the setting information related to wireless communication set in advance in the AP 10, that is, the setting information stored in the preset setting information 161. For this reason, the new AP 10 consistently sets the first wireless communication setting information (preset setting information) used for the guidance 1 to 6 for the terminal 30 before and after acquiring the setting information related to the wireless communication from the existing AP 20. 161) can be maintained. Therefore, guidance using the terminal 30 can be provided in the AP 10 that can duplicate the setting information related to wireless communication set in the AP 20.

  Furthermore, according to the first embodiment, the guide unit 116 of the AP 10 returns to the guides 1 to 6 by returning a response in which the address is replaced in response to an arbitrary Internet connection request received from the terminal 30 (wireless terminal). The series of guides shown, that is, guides related to the replication process are started. For this reason, guidance to the terminal 30 can be started by using a common operation for Internet connection as a trigger without requiring a special operation from the user of the terminal 30. As a result, the AP 10 (wireless connection device) can more reliably carry out guidance to the terminal 30 using the first wireless communication.

  Further, according to the first embodiment, the guide unit 116 of the AP 10 provides guidance 1 for starting the replication process and guidance 2 and 6 for connection (AOSS connection, WPS connection) at the point of the replication process. Then, a WEB page for displaying the guides 3, 4, and 6 for acquiring setting information related to wireless communication is transmitted to the terminal 30. As a result, the guide unit 116 can realize interactive guidance related to acquisition of setting information related to wireless communication from the existing AP 20 (another wireless connection device). As a result, usability for the user of the terminal 30 (wireless terminal) can be further improved. Furthermore, according to the first embodiment (step S102 in FIG. 4 and FIG. 10), the user can use the form in which the user touches the AP 10 (wireless connection device) directly to the existing AP 20 (other wireless connection device). ). Furthermore, according to the first embodiment (step S156 in FIGS. 4 and 10), the AP 10 (wireless connection apparatus) automatically uses the acquired setting information after the acquisition of setting information related to wireless communication is completed. Can be activated as an access point.

B. Second embodiment:
In the second embodiment of the present invention, in the duplication processing described in the first embodiment, that is, in the duplication processing for duplicating “setting information related to wireless communication” set in an existing AP to a new AP, A configuration capable of copying “other setting information” set in the AP to a new AP will be described. Below, only the part which has a different structure and operation | movement from 1st Embodiment is demonstrated. In the figure, the same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment described above, and detailed description thereof is omitted.

B-1. System outline:
FIG. 13 is an explanatory diagram showing a change in the schematic configuration of the network system in the second embodiment. The main difference from the first embodiment shown in FIG. 1 is that an AP 10a is provided instead of the AP 10. In the present embodiment, it is assumed that the existing AP 20 currently in operation is replaced with a new AP 10a.

  FIG. 13A shows a schematic configuration of the network system 1a before the existing AP 20 is replaced with a new AP 10a. The configuration of FIG. 13A is the same as that of the first embodiment described in FIG.

It can be replicated to the AP 10a. After the replication is completed, the existing AP 20 is replaced with a new AP 10a. FIG. 13B shows a schematic configuration of the network system 1a after the existing AP 20 is replaced with a new AP 10a. After completion of the replacement, the configuration of the network system 1a changes to the configuration shown in FIG. 13B, and the user terminal 30 performs wireless communication with the new AP 10a and communication with the Internet INT via the new AP 10a. It becomes possible.

B-2. AP schematic configuration:
FIG. 14 is a block diagram functionally showing the configuration of the AP 10a and the AP 20. As shown in FIG. 14A shows the configuration of the AP 10a, and FIG. 14B shows the configuration of the AP 20. The difference from the first embodiment shown in FIG. 2 is that the AP 10 a includes a CPU 110 a instead of the CPU 110 and a flash ROM 160 a instead of the flash ROM 160.

  The CPU 110 a includes a STA side AOSS processing unit 112 a instead of the STA side AOSS processing unit 112, a STA side WPS processing unit 113 a instead of the STA side WPS processing unit 113, and a guide unit 116 a instead of the guide unit 116. ing. The STA-side AOSS processing unit 112a differs from the first embodiment shown in FIG. 4 in the processing content of the replication processing using AOSS. The STA-side WPS processing unit 113a differs from the first embodiment shown in FIG. 10 in the processing content of the replication processing using WPS. The guidance unit 116a is partially different from the first embodiment shown in FIG. 4 or 10 in the content of guidance in the duplication processing using AOSS or the duplication processing using WPS.

  In addition to the preset setting information 161 and the setting information storage area 162, the flash ROM 160a further includes another setting information storage area 164. The other setting information storage area 164 is an area for storing other setting information acquired from the AP 20 in the duplication processing.

B-3. Schematic configuration of terminal:
The schematic configuration of the terminal 30 in the second embodiment is the same as that of the first embodiment shown in FIG.

B-4. Replication process:
B-4-1. Duplication processing using AOSS:
In the replication process using AOSS in the second embodiment, the AP 10a will be described below after the completion of “temporary communication disconnection” in step S140 of the replication process (FIG. 4) using AOSS in the first embodiment. Execute other setting information acquisition processing. After the other setting information acquisition process is completed, the AP 10a returns to step S144 in FIG. 4 and continues the process.

B-4-2. Copy processing using WPS:
In the duplication processing using WPS in the second embodiment, the AP 10a performs the following other explanations after “temporary communication” in step S234 of the duplication processing (FIG. 10) using WPS in the first embodiment. Execute the setting information acquisition process. After the other setting information acquisition process is completed, the AP 10a returns to step S144 in FIG. 10 and continues the process.

B-4-3. Acquisition of other setting information:
FIG. 15 is a sequence diagram illustrating a procedure of another setting information acquisition process. The procedure of other setting information acquisition processing is common to both replication processing using AOSS and replication processing using WPS. Therefore, hereinafter, a case where the present invention is applied to replication processing using AOSS will be described as an example. When this processing is applied in replication processing using WPS, the description of “STA side AOSS processing unit 112a” in the text is replaced with the description of “STA side WPS processing unit 113a”.

  In step S302, the STA side connection control unit 114y of the AP 10a connects to the AP 20 using the setting information regarding the wireless communication acquired in the duplication process. The STA side AOSS processing unit 112a of the AP 10a transmits a request for other setting information to the AP 20.

  In step S304, the authentication processing unit 215 of the AP 20 requests authentication information in order to authenticate the validity and authority of the AP 10a.

  In step S306, the guide unit 116a of the AP 10a transmits the content of the WEB page for displaying the guide 7 to the terminal 30. Here, the guide 7 is a guide for prompting the user to input authentication information for authentication by the existing AP 20. In step S <b> 308, the WEB browser 311 of the terminal 30 displays the received guidance 7 on the touch panel 360.

  FIG. 16 is an example of a guide 7 screen. On the screen W7 of the guidance 7, there are arranged a message MG7 for prompting input of authentication information, a user name input field T71, a password input field T72, a button B71 to continue without input, and a next button B72.

  In step S310 of FIG. 15, the user inputs the user name of the existing AP 20 in the user name input field T71 of the screen W7, inputs the password of the AP 20 in the password input field T72, and presses the next button B72. In step S312, the WEB browser 311 of the terminal 30 that detects the pressing of the next button B72 transmits the input contents of the user name input field T71 and the password input field T72 to the AP 10a as authentication information. If it is detected that the button B71 continues without being input, the WEB browser 311 of the terminal 30 transmits an end request for another setting information acquisition process (FIG. 15) to the AP 10a. The AP 10a that has received the termination request terminates the processing in FIG.

  In step S314, the STA-side AOSS processing unit 112a of the AP 10a transmits the acquired authentication information candidate to the AP 20.

  In step S316, the authentication processing unit 215 of the AP 20 executes authentication processing for the AP 10a using the received authentication information. Specifically, the authentication processing unit 215 performs authentication by determining whether or not the received authentication information matches the authentication information stored in the flash ROM 260 in advance. In step S318, the authentication processing unit 215 of the AP 20 transmits the result of authentication processing (success / failure) to the AP 10a.

  If the result of the authentication process is “success”, the STA side AOSS processing unit 112a of the AP 10a transmits a request for other setting information to the AP 20 in step S320. On the other hand, if the result of the authentication process is “failure”, the STA-side AOSS processing unit 112a of the AP 10a shifts the process to step S306 and requests the user to input authentication information again.

  In step S322, the authentication processing unit 215 transmits the contents of the other setting information 262 to the AP 10a.

  In step S324, the STA-side AOSS processing unit 112a of the AP 10a acquires other setting information from the AP 20. The STA side AOSS processing unit 112a stores the acquired other setting information in the other setting information storage area 164, and ends the process.

  In this embodiment, the setting information stored in the other setting information storage area 164 is immediately effective in step S156 of the replication process using AOSS (FIG. 4) or the replication process using WPS (FIG. 10). To be.

  As described above, according to the second embodiment, in addition to the effects of the first embodiment, the following effects are further achieved. The STA side AOSS processing unit 112a or the STA side WPS processing unit 113a (acquisition unit) uses the authentication information (a set of user ID and password) acquired from the terminal 30 (wireless terminal) via the first wireless communication, Other setting information other than the setting information related to wireless communication can be acquired from the AP 20 (another wireless connection device). As a result, it is possible to provide the AP 10a (wireless connection device) that can replicate not only the setting information related to wireless communication but also other setting information, and the usability for the user can be further improved.

C. Variations:

Image input / output devices, audio / TV and other AV devices, refrigerators, air conditioners, television and other home appliances, and other devices such as NAS (Network Attached Storage).

Modification 2
In the above embodiment, an example of the configuration of the wireless connection device, the other wireless connection device, and the wireless terminal is given. However, the structure in the said embodiment is an example to the last, and various changes are possible. For example, the deformation | transformation which abbreviate | omits a part of a component, adds a further component, or changes a part of a component is possible.

  For example, the setting buttons provided on the wireless connection device and other wireless connection devices are in a form in which the user directly touches, in a form of short-range communication from the vicinity of the wireless connection apparatus, or information provided by the wireless connection apparatus Various modes can be adopted as long as the code is photographed by a camera built in the client and configured as an input unit that can give an instruction to start processing to the wireless connection device. When the wireless connection device includes a display, the wireless connection device may be realized by a GUI (Graphical User Interface). It may be realized using a GUI of a mobile device (smartphone or the like) capable of wireless communication with the wireless connection device. You may implement | achieve using infrared communication and a contact-type or non-contact-type IC card. You may implement | achieve using information codes, such as QR code (trademark), a barcode, and a hologram. In this way, it is possible to prevent a malicious third party from giving a copy processing start instruction to the wireless connection device against the intention of the user, and leakage of communication information and encrypted information. Can be suppressed.

  For example, the frequency band supported by the wireless communication interface may be three or more. Although 2.4 GHz and 5 GHz have been exemplified as the corresponding frequency bands, the present invention is not limited to these. For example, the wireless communication interface may support other frequency bands such as 60 GHz.

  For example, a wireless connection device or another wireless connection device may not have a function as a router. For example, in another wireless connection device, either the AP side AOSS processing unit or the AP side WPS processing unit may be omitted. Further, for example, the wired communication interface may be omitted in the wireless connection device and other wireless connection devices.

  For example, the flash ROM may be composed of different storage media in the wireless connection device and other wireless connection devices. For example, the wireless connection device and the other wireless connection device may include a removable storage medium such as a USB memory or a USB hard disk instead of the flash ROM. For example, the information described as being stored in the flash ROM in the above embodiment may be distributed and stored in a plurality of storage media.

  For example, as an example of the display unit of the wireless terminal, a touch panel in which a display device such as a liquid crystal screen and an input information acquisition device such as a touch pad are stacked is given. However, the display unit of the wireless terminal may be provided with a display device and an input information acquisition device separately.

However, the processing procedure in the above embodiment is merely an example, and various modifications are possible. For example, some steps may be omitted, and other steps may be added. Further, the order of the steps to be executed may be changed.

  For example, any one of the guides 1 to 6 regarding the duplication processing may be omitted. Further, instead of the guides 1 to 6 regarding the duplication processing or together with the guides 1 to 6, guidance using a display device such as a liquid crystal screen provided in the wireless connection device, an indicator, voice, or the like may be performed.

  For example, in the above-described embodiment, a method provided by another wireless connection device, which transmits wireless communication setting information to a device connected as a wireless communication client, enables wireless communication to the client. AOSS and WPS are illustrated as examples of methods for performing the setting. However, methods other than AOSS and WPS can be used in the duplication processing performed by the wireless connection device.

  For example, the device that is the target of pressing the setting button to start the replication process may be either a wireless connection device or another wireless connection device. In this case, the device (one device) that detects the pressing of the setting button transmits a copy processing start request to the other device, so that the wireless connection device and the other wireless connection device Duplication processing can be started in both apparatuses. The replication processing start request may be included in a specific area of a connection request (association request or authentication request) transmitted from one device to the other device, or may be a single request.

-Modification 4:
In the said embodiment, an example of the acquisition process of other setting information was shown. However, the processing procedure in the above embodiment is merely an example, and various modifications are possible. For example, some steps may be omitted, and other steps may be added. Further, the order of the steps to be executed may be changed.

  For example, as authentication information, instead of a combination of a user ID and a password, a part or all of the PIN number described on the ID card attached at the time of sale of the wireless connection device (included or described in the product package) is used. May be used. The PIN number is a character string indicating a personal identification number used to determine that the user is a valid user of the wireless connection device. Further, as the authentication information, both a combination of a user ID and a password and a part or all of the PIN number may be used together. Further, when the access point transmits setting information related to wireless communication to the client device, the authentication information may be transferred in a manner in which the access point information is notified to the client device. In this case, a restriction that the authentication information is temporarily valid may be added.

-Modification 5:
In the above embodiment, an example of the guidance screen in the duplication processing (duplication processing using AOSS, duplication processing using WPS) and other setting information acquisition processing is shown. However, the screen in the above embodiment is merely an example, and various modifications can be made. For example, some items may be omitted, or item names and layouts may be changed. An item may be added.

  For example, in the guide 4 of the second embodiment (guidance for notifying that copying of setting information related to wireless communication from an existing wireless connection device to a new wireless connection device is completed), setting information related to the copied wireless communication In addition to the contents (items L41 and L42), the contents of other copied setting information may be guided. Then, the user can grasp all the information copied from the other wireless connection device to the new wireless connection device.
