  Next, a procedure for setting the formal wireless setting information set in the wireless access point 1 in the wireless IP phone 2 in the first embodiment will be described. FIG. 4 is a sequence diagram illustrating a procedure for setting a wireless LAN in the wireless LAN system according to the first embodiment.

  First, in step S <b> 10, a setting opportunity input for starting simple setting is performed on the wireless access point 1 by the user. Here, after a user inputs a number such as “*** 55” as a special number for simple setting to the telephone 3 connected to the wireless access point 1, an arbitrary number of digits is used as a temporary password. Is entered.

  Next, in step S <b> 20, the telephone 3 transmits the input temporary password to the wireless access point 1.

  Next, in step S30, the control unit 18 of the wireless access point 1 causes the wireless setting information generation unit 12 to generate wireless setting information for simple setting based on the temporary password transmitted from the telephone 3, and is generated. Wireless setting information for simple setting is set in the wireless communication unit 11. Here, the wireless setting information generation unit 12 generates wireless setting information uniquely determined from the temporary password.

  The wireless setting information includes an SSID that is a name for identifying a specific wireless LAN and a WEP key that is an encryption key when WEP (Wired Equivalent Privacy) is used as an encryption technique.

  In step S40, a setting opportunity input for starting simple setting is performed on the wireless IP phone 2 by the user. The user inputs, for example, “55” as a special number for simple setting from the menu screen in the GUI displayed on the display unit 25 of the wireless IP phone 2, and then inputs “*” to the telephone 3 in step S 10. The same value as the numeric string input after “** 55” is input to the input unit 24 as a temporary password. A number (for example, “55”) for simple setting is set in advance and stored in the storage unit 23.

  Next, in step S50, the control unit 26 of the wireless IP phone 2 causes the wireless setting information generation unit 22 to generate wireless setting information for simple setting based on the temporary password input to the input unit 24. The wireless setting information for simple setting is set in the wireless communication unit 21. Here, the wireless setting information generation unit 22 generates wireless setting information by the same algorithm as the wireless setting information generation unit 12 of the wireless access point 1 and is input to the telephone 3 as a temporary password. When the same value is input, the same wireless setting information is generated.

  When the wireless setting information for simple setting is generated and set in the wireless access point 1 and the wireless IP phone 2, a temporary wireless connection using the wireless setting information for simple setting is established in step S60.

  Thereafter, in step S 70, the wireless IP phone 2 transmits a DHCP request to the wireless access point 1.

Formal wireless setting information is stored in the storage unit 13 in advance. Note that when the wireless setting information transmission request is not transmitted within a predetermined time after the wireless setting information for simple setting is generated (step S30), the control unit 18 forcibly disconnects the wireless connection.

  When the transmission of the formal wireless setting information is completed, in step S110, the control unit 18 of the wireless access point 1 and the control unit 26 of the wireless IP phone 2 disconnect the temporary wireless connection.

  Next, in step S <b> 120, the control unit 26 of the wireless IP phone 2 sets formal wireless setting information in the wireless communication unit 21. In step S <b> 130, the control unit 18 of the wireless access point 1 sets formal wireless setting information in the wireless communication unit 11. Thereby, in step S140, a wireless connection using formal wireless setting information is established.

  As described above, according to the first embodiment, the same wireless setting information for simple setting determined from the same temporary password input to the wireless access point 1 and the wireless IP phone 2 is used as the wireless access point 1 and the wireless IP phone. 2 is used, a temporary wireless connection is established between the wireless access point 1 and the wireless IP phone 2 using the wireless setting information for simple setting, and the formal wireless setting information is set in the temporary wireless connection. Since transmission is performed from the wireless access point 1 to the wireless IP phone 2, wireless setting can be performed with a simple operation, and leakage of wireless setting information due to unauthorized access during wireless setting can be prevented.

  The temporary password does not need to be registered in advance, and the user can use an arbitrary value at the time of wireless setting. Therefore, the trouble that the user forgets the value to be entered can be avoided.

  In the above description, the telephone 3 is used as a temporary password input means for the wireless access point 1, but the input unit 14 such as a numeric keypad provided in the wireless access point 1 may be used instead of the telephone 3.

  In the above description, when the wireless setting is performed, the temporary password is input to both the wireless access point 1 and the wireless IP phone 2, but the wireless access point 1 first inputs the password. You may make it memorize the password.

  In this case, in the subsequent wireless setting, a special number (for example, “*** 55”) for performing simple setting is input to the wireless access point 1 via the telephone 3, thereby generating a wireless setting information generation unit. 12, wireless setting information for simple setting uniquely determined from the password is generated. Then, a number for simple setting (for example, “55”) is input to the wireless IP phone 2 and the same password stored in the wireless access point 1 is input. Based on the password, the wireless setting information generating unit 22 generates the same wireless setting information for simple setting as that generated by the wireless access point 1, and temporarily uses the generated wireless setting information for simple setting. Wireless connection is made.

(Second Embodiment)
Next, a second embodiment will be described. In the first embodiment, the setting trigger input is performed using the telephone 3 connected to the wireless access point 1, but in the second embodiment, the wireless LAN card is inserted and removed as the setting trigger input.

  FIG. 5 is a schematic diagram showing a wireless LAN system according to the second embodiment of the present invention. 5, the wireless LAN system of the second embodiment includes a wireless access point 31, a wireless IP phone 32, and PCs 4 and 5. The wireless access point 31 can be connected to the wireless IP phone 32 and the PC 4 by wireless communication. The wireless access point 31 is connected to the PC 5 via a LAN cable 7 in a wired manner. The wireless LAN system shown in FIG. 5 has a configuration in which a telephone is not connected to the wireless access point 31 with respect to the wireless LAN system shown in FIG.

  FIG. 6 is a block diagram showing a configuration of a wireless access point according to the second embodiment of the present invention. The wireless access point 31 shown in FIG. 6 has a configuration in which the wireless setting information generation unit 12 and the analog telephone port 17 are omitted from the wireless access point 1 of the first embodiment shown in FIG. A wireless LAN card 19 is inserted into the wireless communication unit 11.

  FIG. 7 is a block diagram showing a configuration of a wireless IP phone according to the second embodiment of the present invention. The wireless IP phone 32 shown in FIG. 7 has a configuration in which the wireless setting information generation unit 22 is omitted from the wireless IP phone 2 of the first embodiment shown in FIG. In the constituent elements of the second embodiment shown in FIG. 6 and FIG. 7, the same constituent elements as those in FIG. 2 and FIG.

  Next, a procedure for setting the formal wireless setting information set in the wireless access point 31 in the wireless IP phone 32 in the second embodiment will be described. FIG. 8 is a sequence diagram illustrating a procedure for setting a wireless LAN in the wireless LAN system according to the second embodiment.

  First, in step S210, a setting opportunity input for starting simple setting is performed on the wireless IP phone 32 by the user. The user inputs, for example, “55” as a special number for performing simple setting from the menu screen in the GUI displayed on the display unit 25 of the wireless IP phone 32.

  Next, in step S <b> 220, the control unit 26 of the wireless IP phone 32 sets wireless setting information for simple setting in the wireless communication unit 21. Here, the wireless setting information for simple setting includes an SSID and a WEP key, and is stored in the storage unit 23 in advance.

  Thereafter, in step S230, the wireless IP phone 32 continuously transmits wireless connection requests to the wireless access point 31.

  In step S240, the user inputs a setting opportunity to the wireless access point 31. In the second embodiment, the user inserts and removes the wireless LAN card 19 as a setting opportunity input. When the control unit 18 detects that the wireless LAN card 19 inserted in the wireless communication unit 11 has been removed and is inserted after a predetermined time, the control unit 18 determines that a setting trigger input has been made. Alternatively, it may be determined that a setting opportunity input has been performed by detecting that the wireless LAN card 19 has been inserted.

  Next, in step S250, the control unit 18 controls the wireless communication unit 11 and the wired LAN port 16, so that the wireless IP phone 32 can communicate only with the wireless access point 31, and the wireless access point 31 can be wirelessly or wired. Guards to prevent communication with other devices connected with. For example, the guard is applied by invalidating the communication via the wireless communication unit 11 other than the wireless IP phone 32 and invalidating all the communication via the wired LAN port 16.

  Next, in step S260, the control unit 18 of the wireless access point 31 sets wireless setting information for simple setting in the wireless communication unit 11. Here, the same wireless setting information as the wireless setting information for simple setting stored in the wireless IP phone 32 is stored in the storage unit 13 of the wireless access point 31 in advance.

  In step S270, a temporary wireless connection using the wireless setting information for simple setting is established. Further, when the wireless setting information for simple setting is set in the wireless communication unit 11 and a temporary wireless connection is established, transmission of a continuous wireless connection request from the wireless IP phone 32 ends. Thereafter, Steps S280 to S320 are the same as Steps S70 to S110 of FIG. 4 described in the first embodiment.

  Here, the temporary wireless connection for the simple setting could not be established because the simple setting start operation is not performed on the wireless access point 31 side after the setting trigger for the simple setting is input from the wireless IP phone 32 side. In this case, the wireless IP phone 32 ends the simple setting after a predetermined time has elapsed.

  After the temporary wireless connection is disconnected (step S320), in step S330, the control unit 18 invalidates the guard of communication between the wireless IP phone 32 and the other device connected to the wireless access point 31. Hereinafter, steps S340 to S360 are the same as steps S120 to S140 of FIG. 4 described in the first embodiment.

  As described above, according to the second embodiment, since insertion / extraction of the wireless LAN card 19 is used as an input for setting the simple setting, the wireless access point 31 can perform wireless access even when there is no input means that can be assigned to the simple setting. It is possible to perform a simple setting input for the point 31.

  Also, in the second embodiment, unlike the first embodiment, the temporary password is not input, and the wireless setting information for simple setting uses a preset fixed value. Therefore, when the wireless setting information for simple setting is leaked to an unauthorized user, there is a possibility that the wireless connection is performed illegally immediately after the user gives a simple setting start operation to the wireless access point 31. is there. Therefore, a simple setting start operation is performed from the wireless IP phone 32 side, and wireless connection requests are continuously transmitted. As a result, a temporary wireless connection can be established immediately after the simple setting start operation is performed at the wireless access point 31, so that the time during which the wireless access point 31 is switched to the wireless setting for simple setting is minimized. The possibility of unauthorized connection can be minimized.

  In addition, since communication between the wireless IP phone 32 and other devices connected to the wireless access point 31 is guarded during temporary wireless connection for simple setting, connection by an unauthorized third party during the simple setting Even in the case where the communication is performed, it is possible to suppress a decrease in security by preventing connection to another device.

  In the present embodiment, an example in which a continuous wireless connection request from the wireless IP phone 32 is transmitted until a temporary wireless connection is established has been described, but the present invention is not limited to this. If the wireless access point 31 detects a wireless connection request from the wireless IP phone 32 and notifies the wireless IP phone 32 of the detection, the wireless access point 31 can perform any step after the simple setting start operation (step S240). The transmission of the wireless connection request may be terminated.

(Third embodiment)
Next, a third embodiment will be described. In the third embodiment, wireless connection using the wireless setting information for simple setting is always available. In order to prevent an unauthorized third party wireless terminal from connecting and obtaining formal wireless setting information at the moment when the wireless access point 31 permits the connection of the wireless IP telephone 32, the wireless IP telephone 32 When the connection is established, the temporary issue information is first transmitted from the wireless access point 31 to the wireless IP phone 32. After a certain time, the wireless IP phone 32 transmits the temporary issue information to the wireless access point 31, so that the wireless access point 31 31 is configured to transmit formal wireless setting information to the wireless IP phone 32.

  The configuration of the wireless LAN system of the third embodiment is the same as the configuration of the wireless LAN system of the second embodiment shown in FIG. The configurations of the wireless access point 31 and the wireless IP phone 32 are the same as the configurations of the wireless access point 31 and the wireless IP phone 32 of the second embodiment shown in FIGS.

  Next, a procedure for setting formal wireless setting information set in the wireless access point 31 in the wireless IP phone 32 in the third embodiment will be described. FIG. 9 is a sequence diagram illustrating a procedure for setting a wireless LAN in the wireless LAN system according to the third embodiment.

  First, in step S410, a setting opportunity input for starting simple setting is performed on the wireless access point 31 by the user. Here, when the user presses the button of the input unit 14 provided in the wireless access point 31, the control unit 18 determines that a setting opportunity input has been performed.

  Thereafter, in steps S420 and S430, as in the case of steps S210 and S220 of FIG. 8 described in the second embodiment, setting trigger input of the wireless IP phone 32 and setting of wireless setting information for simple setting are performed.

  In step S440, a temporary wireless connection using the wireless setting information for simple setting is established. In the third embodiment, formal wireless setting information and simple setting wireless setting information are stored in the storage unit 13 in advance. A wireless connection using formal wireless setting information and a wireless connection using simple setting wireless setting information are always available. Here, a device connected through wireless connection using the wireless setting information for simple setting is guarded at the wireless access point 31 so that it cannot be connected to other than the wireless access point 31.

  Thereafter, steps S450 and S460 are the same as steps S280 and S290 of FIG. 8 described in the second embodiment.

  In step S 470, the wireless IP phone 32 transmits a wireless setting information provisional issue request to the wireless access point 31. Next, in step S480, the control unit 18 generates temporary issue information and causes the wireless communication unit 11 to transmit the temporary issue information to the wireless IP phone 32. The provisional issue information is generated as different information each time it is transmitted in order to be used as temporary key information when transmitting formal wireless setting information. Here, if the simple setting start operation (step S410) of the wireless access point 31 is not performed, the wireless access point 31 does not transmit provisional issue information.

  Next, in steps S490 and S500, the wireless IP phone 32 and the wireless access point 31 wait for a certain time. If the wireless access point 31 receives another temporary issue request during this standby, the wireless access point 31 invalidates the previously issued temporary issue information and ends the simple setting process.

  Thereafter, in step S510, the wireless IP phone 32 transmits a transmission request for wireless setting information including provisional issue information received from the wireless access point 31.

  In step S520, the control unit 18 of the wireless access point 31 determines whether or not the temporary issue information included in the wireless setting information transmission request transmitted from the wireless IP telephone 32 matches the temporary issue information transmitted by itself. Judging. If they match, in step S520, the control unit 18 controls to transmit formal wireless setting information. If they do not match, the control unit 18 ends the simple setting process.

  It should be noted that encryption using HTTPS (Hypertext Transfer Protocol Security) or the like is performed when transmitting formal wireless setting information or provisional issue information. The same applies to the transmission of formal wireless setting information in other embodiments.

  When the transmission of the formal wireless setting information is completed, in step S540, the control unit 18 of the wireless access point 31 and the control unit 26 of the wireless IP phone 32 disconnect the temporary wireless connection.

  Next, in step S550, the control unit 26 of the wireless IP phone 32 sets formal wireless setting information in the wireless communication unit 21. Thereby, in step S560, a wireless connection using formal wireless setting information is established.

  As described above, according to the third embodiment, since wireless connection using the wireless setting information for simple setting is always available in the wireless access point 31, the wireless setting is used for simple setting when performing simple setting. There is no need to switch to a specific one, and the setting can be easily performed without temporarily interrupting the formal wireless setting.

  Further, when the wireless access point 31 receives another temporary issue request during a certain period after transmitting the temporary issue information, the wireless access point 31 invalidates the previously issued temporary issue information and ends the simple setting process. Therefore, when multiple users request transmission of wireless settings, transmission of wireless settings can be canceled, and unauthorized third parties formally aim at the moment when authorized users make simple settings. It is possible to prevent acquisition of wireless setting information.

  Here, as a method of preventing connection by an unauthorized third party, in addition to the method of presenting provisional issue information as described above, the wireless access point 31 is wirelessly set a certain time before a simple setting start operation is performed. When a transmission request for setting information is transmitted, a method of invalidating the simple setting start operation can be used. In addition, when the wireless access point 31 confirms that a new connection request such as a wireless connection request or a DHCP request, a transmission request for wireless setting information, etc. is transmitted before the temporary wireless connection is started, The wireless setting information may not be transmitted. These methods need not be used simultaneously with the method of presenting provisional issue information, and may be used alone.

  In the third embodiment, the input unit 14 provided in the wireless access point 31 is used for setting trigger input to the wireless access point 31, but setting is performed by inserting / removing the wireless LAN card as in the second embodiment. An opportunity input may be performed.

  In the description of each embodiment, it is assumed that the formal wireless setting information is stored in advance in the storage unit 13 of the wireless access point 1, but a temporary wireless connection is established and a request for transmission of the wireless setting information is made. The wireless access point 1 may dynamically generate formal wireless setting information after reception.

  In each embodiment, the case where the wireless terminal is wirelessly set as a wireless terminal has been described. However, the wireless terminal is not limited to this, and may be a PC or the like. Further, although WEP is used as the encryption technique, other encryption techniques other than WEP may be used.
