The CPU 300 is executed according to a program stored in the ROM 301.

  The radio terminal 100 receives a notification signal (normal mode) periodically transmitted by the base station 103 and the base station 105 (S700, S701). Here, the user of the wireless terminal 100 desires to connect the wireless terminal 100 to the base station 103 and perform data communication. Therefore, the user of the wireless terminal 100 wants to set the wireless parameter of the base station 103 managed by the management apparatus 102 in the wireless terminal 100.

  The user of the wireless terminal 100 puts the management device 102 that manages the wireless parameters of the base station 103 into the setting mode, and uses the management device 102 to perform the wireless parameter automatic setting of the wireless terminal 100, so that the setting button 304 of the management device 102 is used. Is pressed (S702, 900). When the management apparatus 102 detects that the setting button 304 is pressed, it changes the operation mode corresponding to the own apparatus in the management apparatus information unit 305 to “1”, transitions from the normal mode to the setting mode, and the base station 103 to be managed. Is notified of the start of the setting mode (S703, 901). At this time, it is assumed that the setting button 304 of the management apparatus 106 is also pressed by another user (S704, 900). When detecting that the setting button 304 is pressed, the management apparatus 106 notifies the base station 105 of the start of the setting mode (S705, 901). When entering the setting mode, the management apparatuses 102 and 106 monitor whether a duplicate notification and a setting request from a wireless terminal, which will be described later, are received.

  The base station 103 and the base station 105 that are notified of the start of the setting mode set the mode area 400 in the broadcast signal reservation area to “1”, and transmit the broadcast signal (setting mode).

  The user of the wireless terminal 100 presses the setting button 203 in order to set the wireless terminal 100 to the setting mode (S706, 800). When detecting that the setting button 203 is pressed, the wireless terminal 100 is a base station connected to the management apparatus 102, and starts scanning for a predetermined time in order to search for the base station 103 operating in the setting mode (801). ). When the radio terminal 100 receives the broadcast signal (setting mode) transmitted from the base stations 103 and 105 after starting the scan (S707, S708, 802), the base station information unit 205 informs the base station information unit 205 of the base station that can be identified from the received broadcast signal. Information is stored (803).

  FIG. 5 shows the state of the base station information unit 205 when the notification signals of the base stations 103 and 105 are received as in the example of FIG. As can be seen from FIG. 5, the base station 103 and the base station 105 are the same except for the MAC address 501.

  When the scanning is completed (YES in 804), the wireless terminal 100 determines the number of base stations in the setting mode (805).

  Here, if there is one base station in the setting mode (“1” in 805), the wireless terminal 100 connects to that base station using a packet that can be communicated regardless of the wireless parameters set in the base station. To send a setting request to the management device. The base station that has received this setting request transfers it to a management device that manages its own radio parameters. When the management device detects the setting request, the management device notifies the wireless terminal that transmitted the request of the managed wireless parameter, and performs wireless parameter setting processing between the wireless terminal and the management device (811, 906). When the setting of the radio parameters is completed, the management apparatus notifies the base station of the setting mode end. When receiving the setting mode end notification from the management apparatus, the base station switches to the normal mode. The wireless terminal 100 sets the wireless communication parameters provided from the management apparatus 102 and is connected to the base station 103 that operates in the normal mode to enable data communication. In the above description, communication is performed with the management apparatus using a packet that can be communicated regardless of the radio parameters set in the base station. However, when the setting mode is entered, the base station and the wireless terminal are switched to predetermined wireless parameters for setting so that communication between the wireless terminal and the base station can be performed, and communication between the wireless terminal and the management apparatus can be performed. May be. Also in the following description, the communication at the time of setting the wireless parameter is performed by the same method.

  If there is no base station in the setting mode and it is 0 (“0” in 805), the setting mode of itself is terminated (812).

  In the example of FIG. 5, since both the base station 103 and the base station 105 operate in the setting mode, the wireless terminal 100 determines that there are a plurality of base stations in the setting mode (“plural” in 805). In this case, the radio terminal 100 notifies the setting mode duplication notification to the base station 103 and the base station 104 operating in the setting mode (S709, S710, 806). When duplicate notification is sent to all base stations operating in the setting mode (YES in 807), the wireless terminal 100 starts the timer 206 (S711, 808).

  When the setting mode duplication notification received by the base station 103 in S709 is transferred from the base station 100 (YES in 902), the management apparatus 102 searches for a management apparatus (903). Then, the information of the searched management device is stored in the management device information unit 305. As a search method, there is a method of making a search request to all the devices connected on the wired LAN 107.

  In response to the search request transmitted in S712, the management apparatus 102 receives a search response from the management apparatus 106 (S713). Then, the management apparatus 102 and the management apparatus 106 mutually confirm the managed wireless parameters (S714, 904), and store the confirmed wireless parameters in the management apparatus information unit 305. Then, the management apparatus 102 compares and confirms whether the wireless parameter of the management apparatus 106 stored in the management apparatus information unit 305 is the same as the wireless parameter managed by the management apparatus 106 (905).

  FIG. 6 shows the state of the management apparatus information unit 305 at that time. According to FIG. 6, it can be seen that the wireless parameter managed by the own device (that is, the management device 102) and the wireless parameter managed by the management device 106 are the same (YES in 905). By the way, even if there are a plurality of base stations operating in the setting mode, it is obvious that the radio terminal 100 may receive the radio parameter from any management device as long as the radio parameters are the same. That is, even when the base stations 103 and 105 are operating in the setting mode, the management apparatus 102 that manages the radio parameters of the base station 103 and the management apparatus 106 that manages the radio parameters of the base station 105 manage the same radio parameters. If the wireless terminal 100 receives the wireless parameter from any management device, the same wireless parameter is set. Accordingly, in such a case, the base station 103 and the base station 105 continue to periodically transmit the notification signal of the setting mode without ending the setting mode (S715, S716).

  When the wireless parameter of the searched management device 106 is the same as the wireless parameter managed by the management device 102 (YES in 905), the management device 102 waits for a setting request from the wireless terminal, and when a setting request is detected, A wireless parameter setting process is performed with the wireless terminal (906).

  The wireless terminal 100 determines whether the base station 103 and the base station 105 end the setting mode before the timer 206 activated in 808 times out. In the example of FIG. 7, the base station 103 and the base station 105 regularly transmit a setting mode notification signal (S715, S716), so that the radio terminal 100 detects the end of the base station setting mode. (NO in 809), the timer 206 times out (S717, 810). Then, the wireless terminal 100 connects to the base station operating in the setting mode, transmits a setting request to the management apparatus, and performs wireless parameter setting processing with the management apparatus (811, 906). In the example of FIG. 7, the wireless terminal 100 is connected to the base station 103 (S718), and sets wireless communication parameters with the management apparatus 102 (S720, 811, 906). When the setting of the radio parameters is completed, the management apparatus notifies the base station of the setting mode end. When receiving the setting mode end notification from the management apparatus, the base station switches to the normal mode. The wireless terminal 100 sets the wireless communication parameters provided from the management apparatus 102 and is connected to the base station 103 that operates in the normal mode to enable data communication.

  Here, FIG. 10 shows a sequence when the radio parameters managed by the management apparatus 102 and the management apparatus 106 are different.

  If the management device 102 and the management device 106 determine that the wireless parameters are not the same (NO in 905), they notify the base station 103 and the base station 105, respectively, of the setting mode (S1000, S1001, 908). Then, the management device 102 and the management device 106 end their own setting mode (909). Upon receiving the setting mode end notification (S1000, S1001), the base station 103 and the base station 105 periodically transmit a normal mode notification signal in which the mode area 400 of the notification signal is set to “0” (S1002, S1003). .

  The wireless terminal 100 receives the normal mode notification signal before the timer 206 times out (S1002, S1003), detects that the base station 103 and the base station 105 have ended the setting mode (YES in 809), and sets The mode is terminated (S1004, 812).

  As described above, in the present embodiment, when a plurality of base stations operating in the setting mode are detected, the wireless terminal notifies the base station of duplication, and the setting mode is sent to the management apparatus via the base station. Added duplicate notification. Thereby, the management apparatus and the base station can finish the setting mode at an early stage.

  Further, when there are a plurality of management devices in the setting mode, the management device confirms whether the wireless parameters managed by each device match or not. Thereby, when the wireless parameters managed by the management device in the setting mode match and the same wireless parameter is set in the wireless terminal no matter which management device is set, the setting mode is continued, Wireless parameter setting can be performed.

  In the present embodiment, the wireless terminal 100 ends the setting mode when it detects the end of the setting mode of the base station between the start and the end of the timer 206. However, the management device may transmit a wireless parameter match notification or a mismatch notification to the wireless terminal via the base station. In this case, the wireless terminal ends the setting mode when receiving the mismatch notification, and continues the setting mode when receiving the matching notification.

(Second Embodiment)
In the present embodiment, the radio parameters managed by the management apparatus are grouped in advance, and the base station broadcasts identification information of the group of radio parameters managed by the management apparatus. The wireless terminal analogizes parameter matching / mismatching from the group identification information.

  Hereinafter, the present embodiment will be described with reference to the drawings. In addition, about the part already demonstrated, description is abbreviate | omitted by attaching | subjecting the same code | symbol. The configurations of the wireless terminals 100 and 104 and the management devices 102 and 106 are the same as those in the first embodiment.

  FIG. 11 shows a reserved area for a broadcast signal transmitted by the base station in the present embodiment. In this embodiment, a part of the reserved area is used to indicate the group to which the base station belongs. In the present embodiment, it is assumed that the same radio parameter is set for base stations in the same group.

  FIG. 12 shows the configuration of the base station information unit 205 of the wireless terminal in this embodiment. The base station information unit 205 stores identification information 1200 of a group to which each base station belongs.

  FIG. 13 is a flowchart showing the operation of the wireless terminal according to the present embodiment. The CPU 200 is executed according to a program stored in the ROM 201. FIG. 14 is a flowchart showing the operation of the management apparatus according to the present embodiment. The CPU 300 is executed according to a program stored in the ROM 301.

  Also in this embodiment, the user of the wireless terminal 100 desires to connect the wireless terminal 100 to the base station 103 and perform data communication. Therefore, the user of the wireless terminal 100 wants to set the wireless parameter of the base station 103 managed by the management apparatus 102 in the wireless terminal 100.

  The user of the wireless terminal 100 puts the management device 102 that manages the wireless parameters of the base station 103 into the setting mode, and uses the management device 102 to perform the wireless parameter automatic setting of the wireless terminal 100, so that the setting button 304 of the management device 102 is used. Is pressed (900).

  When the management apparatus 102 detects that the setting button 304 is pressed, it changes the operation mode corresponding to the own apparatus in the management apparatus information unit 305 to “1”, transitions from the normal mode to the setting mode, and the base station 103 to be managed. Is notified of the start of the setting mode (901). In addition, the management apparatus 102 notifies the base station 103 of the group number of the wireless parameter to be managed (1400). Here, it is assumed that the management apparatus 102 notifies the base station 103 of the group number “1”. The base station 103 indicates the setting mode and starts to transmit a notification signal indicating the group number “1” periodically. At this time, it is assumed that the setting button 304 of the management apparatus 106 is also pressed by another user. When the management apparatus 106 detects that the setting button 304 is pressed (900), it notifies the base station 105 of the start of the setting mode (901). In addition, the management apparatus 106 notifies the base station 105 of the group number of the wireless parameter to be managed (1400). Here, it is assumed that the management apparatus 106 also notifies the base station 105 of the group number “1”. The base station 105 indicates the setting mode and starts to transmit a notification signal indicating the group number “1” periodically. In addition, when entering the setting mode, the management apparatuses 102 and 106 monitor whether a duplicate notification and a setting request from the wireless terminal are received.

  The user of the wireless terminal 100 presses the setting button 203 to set the wireless terminal 100 to the setting mode (800). When detecting that the setting button 203 is pressed, the wireless terminal 100 is a base station connected to the management apparatus 102, and starts scanning for a predetermined time in order to search for the base station 103 operating in the setting mode (801). ). When the radio terminal 100 receives the broadcast signal (setting mode) transmitted from the base stations 103 and 105 after the start of scanning (802), the base station information unit 205 informs the base station information section 205 of the base stations 103 and 105 that are known from the received broadcast signal. Is stored (803). FIG. 12 shows the state of the base station information unit 205 when the broadcast signals of the base station 103 and the base station 105 are received. As can be seen from FIG. 12, there are two base stations in the set group, and the base station 103 and the base station 105 transmit the broadcast signal having the same group number.

  When the scanning is completed (YES in 804), the wireless terminal 100 determines the number of base stations in the setting mode (805). Referring to the base station information unit 205 in FIG. 12, since there are two base stations in the setting mode (“plural” in 805), the radio terminal 100 uses the base station group stored in the base station information unit 205. Is confirmed (1300).

  When the number of base stations in the setting mode is 1 or 0, the same processing as in FIG. 8 is performed.

  In the example of FIG. 12, since the group (1200) of the base station 103 and the base station 105 is both “1”, the wireless terminal 100 determines that they are the same group (YES in 1301). When the group numbers indicated by the broadcast signals transmitted by the base stations in the setting mode all match, the radio parameters managed by the management apparatus that manages the radio parameters of these base stations are the same. Therefore, the same wireless parameter is set regardless of which management apparatus receives the wireless parameter. In such a case, the wireless terminal 100 continues the setting mode, connects to the base station in the setting mode, and performs wireless parameter setting processing with the management apparatus (811). When the setting of the radio parameters is completed, the management apparatus notifies the base station of the setting mode end. When receiving the setting mode end notification from the management apparatus, the base station switches to the normal mode. The wireless terminal 100 sets the wireless communication parameters provided from the management apparatus 102 and is connected to the base station 103 that operates in the normal mode to enable data communication.

  Also, if the group 1200 of the base station information unit 205 stored in 803 is different, the wireless terminal 100 performs a setting mode duplication notification to all base stations stored in the base station index number 500 (806). The setting mode is terminated (812). Here, duplicate notification is sent to the base station 103 and the base station 105.

  When the duplication notification is transferred from the base station 103 and the base station 105 (YES in 902), the management device 102 and the management device 106 send a setting mode end notification to the base station 103 and the base station 105 (908). ), The setting mode is terminated (909).

  As described above, in the present embodiment, when the wireless terminal detects a mismatch of the group numbers included in the notification signal, the wireless terminal transmits a duplicate notification. Also, the management apparatus ends the setting mode when receiving a duplicate notification. This makes it possible to omit the processing of the search request (S712), search response (S713), and wireless communication parameter confirmation (S714) in FIG. 10 (sequence of the first embodiment). It is possible to end the station setting mode. Similarly to the first embodiment, even when there are a plurality of management devices in the setting mode, if the wireless parameters managed by them match, the setting mode is continued so that the wireless parameter can be set. can do.

(Third embodiment)
In this embodiment, the wireless terminal displays a message for prompting the display unit 207 to press the setting button 304 of the management apparatus again for a certain period of time before the wireless terminal finishes its setting mode in FIGS. To do.

  FIG. 15 is a sequence diagram of this embodiment. FIG. 16 is a flowchart showing the operation of the wireless terminal according to the present embodiment. The CPU 200 is executed according to a program stored in the ROM 201. In addition, about the part already demonstrated, description is abbreviate | omitted by attaching | subjecting the same code | symbol. The configurations of the wireless terminals 100 and 104 and the management devices 102 and 106 are the same as those in the first embodiment.

  In S1002 and S1003, when the wireless terminal 100 detects that the base station 103 and the base station 105 have ended the setting mode (YES in 809), the wireless terminal 100 displays a display prompting the user to press the setting button 304 of the management apparatus again. This is performed for a certain time (S1500, 1600). Also, in the case where no base station in the setting mode is detected in step 805, the wireless terminal 100 displays on the display unit 207 a prompt to press the setting button 304 of the management device again (1600).

  It is assumed that the user of the wireless terminal 100 presses the setting button 304 of the management apparatus 102 again according to the display (S1501). When the setting button 304 is pressed again after completing the setting mode (909 in FIG. 9), the management apparatus 102 returns to step 900 and notifies the base station 103 of the start of the setting mode (901, S1502).

  The base station 103 transmits a notification signal indicating that it is in the setting mode (S1503). At this time, if the setting button 304 is not pressed in the management apparatus 106, the base station 105 transmits a normal mode notification signal.

  The wireless terminal 100 receives the notification signal in S1503, and detects the base station 103 that is in the setting mode (1601). The wireless terminal 100 connects to the base station in the setting mode detected first after displaying the setting button re-pressed, and executes the setting of wireless communication parameters with the management apparatus (811). In the example of FIG. 15, since a notification signal (setting mode) from the base station 103 is detected (S1601), the wireless communication parameter is set with the management apparatus 102 by connecting to the base station 103 (S1506, 811). When the setting of the radio parameters is completed, the management apparatus notifies the base station of the setting mode end. When receiving the setting mode end notification from the management apparatus, the base station switches to the normal mode. The wireless terminal 100 sets the wireless communication parameters provided from the management apparatus 102 and is connected to the base station 103 that operates in the normal mode to enable data communication. If the wireless terminal 100 cannot detect the base station in the setting mode even after a predetermined time has elapsed after the setting button is pressed again, the wireless terminal 100 ends the setting mode (812).

  In the above description, when the end of the setting mode of the base station is detected in FIG. 16, a display prompting the user to press the setting button 304 of the management apparatus again is displayed on the display unit 207. However, the above display may be performed after the duplicate notification (806) to the base station shown in FIG. Also in this case, after displaying the setting button re-pressed, the wireless terminal 100 connects to the base station in the setting mode detected first, and executes the setting of wireless communication parameters with the management apparatus.

  As described above, in this embodiment, when the wireless terminal detects that the base station has finished the setting mode, the wireless terminal displays on the display unit a prompt to press the setting button of the management apparatus again. Then, wireless parameters are set with the management apparatus via the base station in the setting mode detected first. As a result, in addition to the effects of the first embodiment and the second embodiment, it is easy to receive wireless parameters from a desired management apparatus.

(Fourth embodiment)
Also in the present embodiment, the wireless terminal performs a display for urging the display unit 207 to press the setting button 304 of the management apparatus again for a certain period of time before the wireless terminal ends its setting mode in FIGS. To do. Then, when the setting button 304 of the management device is pressed again, the management device requests the base station to change the content of the notification signal, and changes the content of the notification signal.

  FIG. 17 is a flowchart showing the operation of the wireless terminal according to the present embodiment. The CPU 200 is executed according to a program stored in the ROM 201. FIG. 18 is a flowchart showing the operation of the management apparatus according to the present embodiment. The CPU 300 is executed according to a program stored in the ROM 301. In addition, about the part already demonstrated, description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  In S1002 and S1003, when the wireless terminal 100 detects that the base station 103 and the base station 105 have ended the setting mode (YES in 809), the wireless terminal 100 displays a display prompting the user to press the setting button 304 of the management apparatus again. This is performed for a certain time (S1500, 1600). Also, in the case where no base station in the setting mode is detected in step 805, the wireless terminal 100 displays on the display unit 207 a prompt to press the setting button 304 of the management device again (1600).

  It is assumed that the user of the wireless terminal 100 presses the setting button 304 of the management apparatus 102 again according to the display.

  When the setting button 304 is pressed again after completing the setting mode (909 in FIG. 9) (1800), the management apparatus 102 requests the base station to change the content of the notification signal (1801) and notifies the base station. The information of the reserved area of the signal is changed. When the base station receives a change in the content of the notification signal from the management device, the base station transmits the notification signal with the changed content. For changing the information of the reserved area of the notification signal, for example, there is a method of storing a random value in a specific area of the reserved area and changing it.

  When the radio terminal 100 detects a change in the broadcast signal (YES in 1700), the radio terminal 100 connects to the base station that first detected the change in the broadcast signal, and executes radio parameter setting with the management apparatus (811, 906). ). When the setting of the radio parameters is completed, the management apparatus notifies the base station of the setting mode end. When receiving the setting mode end notification from the management apparatus, the base station switches to the normal mode. The wireless terminal 100 sets the wireless communication parameters provided from the management apparatus 102 and is connected to the base station 103 that operates in the normal mode to enable data communication. If the wireless terminal 100 cannot detect the base station in the setting mode even after a predetermined time has elapsed after the setting button is pressed again, the wireless terminal 100 ends the setting mode (812).

  In the above description, when the end of the setting mode of the base station is detected in FIG. 17, a display prompting the user to press the setting button 304 of the management apparatus again is displayed on the display unit 207. However, the above display may be performed after the duplicate notification (806) to the base station shown in FIG. Also in this case, after displaying the setting button re-pressed, the wireless terminal 100 connects to the base station that first detected the change in the notification signal, and executes the setting of wireless communication parameters with the management apparatus.

  As described above, when the setting button is pressed again, the management device changes the content of the notification signal transmitted by the base station. The wireless terminal is connected to the first base station whose notification signal has been changed, and performs wireless parameter setting with the management apparatus. As a result, in addition to the effects of the first embodiment and the second embodiment, it is easy to receive wireless parameters from a desired management apparatus.

(Fifth embodiment)
In the present embodiment, when there are a plurality of setting mode management apparatuses, the SN ratio (Signal / Noise ratio) of the notification signal transmitted by the base station is compared, and the base station to be connected is selected. This is effective when the distance between the base station and the management apparatus is short, for example, when the base station and the management apparatus are in the same casing. That is, when the distance between the base station and the management apparatus is close, if the user holds the wireless terminal and presses the setting button 304 of the management apparatus, the distance between the wireless terminal and the base station also decreases.

  The configuration of the management apparatuses 102 and 106 is the same as that of the first embodiment, but the management apparatus 102 is installed at a position close to the base station 103, or the management apparatus 102 and the base station 103 are configured in the same casing. . Further, the management apparatus 106 is installed at a position close to the base station 105, or the management apparatus 106 and the base station 105 are configured in the same casing. The configuration of the wireless terminals 100 and 104 is different from that of the RAM, but the other configuration of the wireless terminal is the same as that of the first embodiment.

  FIG. 19 shows the configuration of the RAM 202 of the wireless terminal in this embodiment. In the RAM 202, an SN difference storage unit 1900 exists.

  FIG. 20 shows the configuration of the SN difference storage unit 1900. The SN difference storage unit 1900 is used when the wireless terminal 100 compares the SN ratios of the notification signals transmitted by the two base stations and determines whether or not the connection destination can be determined. The SN ratio column 2000 corresponds to the larger value of the SN ratios to be compared, and is divided into certain ranges. The difference minimum value column 2001 shows the minimum value of the difference between the value with the larger SN ratio and the value with the smaller SN ratio.

  For example, when the SN ratio of the notification signal of the base station 103 received by the wireless terminal 100 is 0x19 and the SN ratio of the notification signal of the base station 105 is 0x16, the difference is 0x03. According to FIG. 20, if the SN ratio is 0x20-0x17 (the SN ratio of the broadcast signal of the base station 103 corresponds to this), the minimum difference that can be determined as the connection destination is 0x05. The SN difference between the base station 103 and the base station 105 is 0x03, which does not meet this condition. Therefore, it is determined that the connection destination cannot be determined. The difference in the minimum value for each SN column 2000 is due to the propagation characteristics of radio waves.

  FIG. 21 shows the base station information unit 205 of the wireless terminal 100 in the present embodiment. In this embodiment, the SN ratio 2100 of the signal transmitted by the base station is added to the base station information section shown in FIG.

  FIG. 22 is a flowchart showing the operation of the wireless terminal according to the present embodiment. The CPU 200 is executed according to a program stored in the ROM 201. The operation of the wireless terminal 100 will be described below using FIGS. 19 to 22. Since the operation of the management apparatus is the same as that of the first embodiment, the description thereof is omitted.

  Also in this embodiment, the user of the wireless terminal 100 desires to connect the wireless terminal 100 to the base station 103 and perform data communication. Therefore, the user of the wireless terminal 100 wants to set the wireless parameter of the base station 103 managed by the management apparatus 102 in the wireless terminal 100.

  In FIG. 22, when the setting button 203 is pressed (800), the wireless terminal 100 starts scanning for a certain period of time in order to search for the base station 103 (801). After starting the scan, when the radio terminal 100 receives the broadcast signal (setting mode) transmitted from the base stations 103 and 105 (802), the base station information unit 205 stores the base station information known from the received broadcast signal. (803).

  When the scanning is completed (YES in 804), the wireless terminal 100 determines the number of base stations in the setting mode (805).

  If there is one base station in the setting mode (“1” in 805), the wireless terminal 100 connects to the corresponding base station and performs wireless parameter setting processing with the management apparatus (811). If the base station in the setting mode is 0 (“0” in 805), the own setting mode is terminated (812).

  When determining that there are a plurality of base stations in the setting mode (“plural” in 805), the wireless terminal 100 compares the SN ratios of the notification signals transmitted by the base stations (2200). In the example of FIG. 21, the radio terminal 100 compares the SN ratios of the notification signals transmitted by the base station 103 and the base station 105 (2200). According to FIG. 21, the SN ratio of radio waves received from the base station 103 received by the wireless terminal 100 is 0x16, and the SN ratio of radio waves received from the base station 105 is 0x0f. The difference is 0x07.

  Here, in FIG. 20, when the SN ratio is 0x16, the minimum value of the difference from which the connection destination can be determined is 0x04. Accordingly, the wireless terminal 100 determines that the connection destination can be selected (YES in 2201), and determines the base station 103 having the larger SN ratio as the connection destination (2202). The wireless terminal 100 then connects to the base station 103 and performs wireless parameter setting processing with the management apparatus 102 (811). When the setting of the radio parameters is completed, the management apparatus notifies the base station of the setting mode end. When receiving the setting mode end notification from the management apparatus, the base station switches to the normal mode. The wireless terminal 100 sets the wireless communication parameters provided from the management apparatus 102 and is connected to the base station 103 that operates in the normal mode to enable data communication.

  In step 2201, if the difference in the S / N ratio between the notification signals of the base station 103 and the base station 105 is smaller than the minimum difference 2001 in FIG. 20, the radio terminal 100 determines that the connection destination cannot be selected ( NO in 2201). Then, a duplicate notification is transmitted to the base station 103 and the base station 105 (806). Subsequent processing is the same as in the first embodiment. Moreover, you may perform the process of 3rd Embodiment and 4th Embodiment.

  In the above description, the SN ratios are compared when a plurality of setting mode base stations are detected. However, in FIG. 13, when a plurality of base stations in the setting mode are detected (“plural” in 805), the SN ratios may be compared to select a base station.

  Further, in the present embodiment, the SN ratio is described as representing radio wave quality. However, the received electric field strength (RSSI) and other information are the same as long as they represent radio wave quality. An effect is obtained.

  As described above, according to the present embodiment, when there are a plurality of connection destination candidates, the wireless terminal determines the connection destination using the received radio wave state. Furthermore, since it is determined whether or not the connection destination can be determined based on the difference in the radio wave state, the risk of connecting to an undesired connection destination can be reduced.

This embodiment is particularly effective in the following cases.
1. The base station and the management device are installed close together or in the same housing.
2. With the user wearing the wireless terminal, the user presses the setting button on the management device and the setting button on the wireless terminal.

  In the state as described above, the signal-to-noise ratio of the signal of the base station to which connection is desired is large, and the signal-to-noise ratio of other base stations is expected to be relatively small. Therefore, the radio parameter for connecting to the base station desired by the user Is likely to be set.

(Sixth embodiment)
In the present embodiment, in the fifth embodiment, when the connection destination is determined using the SN ratio, the user is made to confirm the connection destination using the blinking pattern of the LED of the wireless terminal and the management device. .

  In the wireless terminal and the management device in the present embodiment, an LED as a display unit is added to the configuration shown in FIGS.

  FIG. 23 is a flowchart showing the operation of the wireless terminal according to the present embodiment. The CPU 200 is executed according to a program stored in the ROM 201. FIG. 24 is a flowchart showing the operation of the management apparatus according to the present embodiment. The CPU 300 is executed according to a program stored in the ROM 301. In addition, about the part already demonstrated, description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  As described in FIG. 22, when the wireless terminal 100 selects a connection destination using the SN ratio in 2202, the wireless terminal 100 transmits an LED blinking pattern to the connection destination base station (2300). Also, its own LED is caused to blink with the same blinking pattern as that transmitted to the base station (2301).

  The base station that has received the LED blinking pattern transfers the LED blinking pattern to a management device that manages its own wireless parameters. When the base station 103 receives the blinking pattern of the LED, the received blinking pattern is transferred to the management apparatus 102.

  Upon receiving the LED blinking pattern from the base station 103 (2400), the management apparatus 102 causes its own LED to blink with the received blinking pattern (2401).

  The wireless terminal 100 blinks the LED in 2301, and then displays on the display unit 207 that the user confirms the blinking pattern of the LED of the desired connection destination (in this case, the management apparatus 102). Then, the wireless terminal 100 performs display for allowing the user to select connection or disconnection (2302).

  When “connection” is selected by the user who confirmed the display in 2302 (YES in 2303), the wireless terminal 100 connects to the base station (base station 103) selected using the SN ratio, and the management apparatus 102 And wireless parameter setting processing (811, 906). When the setting of the radio parameters is completed, the management apparatus notifies the base station of the setting mode end. When receiving the setting mode end notification from the management apparatus, the base station switches to the normal mode. The wireless terminal 100 sets the wireless communication parameters provided from the management apparatus 102 and is connected to the base station 103 that operates in the normal mode to enable data communication.

  When “end” is selected by the user who confirmed the display in 2302, the radio terminal 100 performs duplication notification to all the base stations (806). Subsequent processing is the same as in the first embodiment. Moreover, you may perform the process of 3rd Embodiment and 4th Embodiment.

  In the above description, the SN ratios are compared when a plurality of setting mode base stations are detected. However, as in the fifth embodiment, when a plurality of base stations in the setting mode are detected in FIG. 13 (“plurality” in 805), the base station is selected using the SN ratio, and the selected base station is selected. The processing after 2300 may be performed.

  Further, instead of the S / N ratio, other information indicating the quality of radio waves such as received electric field strength (RSSI) may be used.

  As described above, in this embodiment, after the wireless terminal determines the connection destination, the wireless terminal performs display that allows the user to select connection / disconnection based on the blinking pattern of the LED. As a result, the user of the wireless terminal can visually check the connection destination, and the risk of erroneously setting wireless parameters with an undesired management device can be reduced. In addition, when there are a plurality of setting mode base stations, the LED is used for confirmation. Therefore, when there is only one setting mode base station, it is not necessary to check the LEDs, and the radio parameters can be set at an early stage. Can be processed.

  In the present embodiment, the user can visually confirm the blinking pattern of the LED, but this may be visible other than the LED or may be a sound.

(Seventh embodiment)
In the first to sixth embodiments, the wireless terminal detects the base station that is in the setting mode (for example, 801 to 804 in FIG. 8). In the present embodiment, the management apparatus searches for a base station in the setting mode and performs duplicate notification.

  FIG. 25 is a system configuration diagram of this embodiment. The management apparatus 102 is connected to the base station 103 by a wireless 2500. The management device 106 is connected to the base station 105 by a radio 2501. In the first to sixth embodiments, the base station has the base station information unit 205 (FIG. 5) in the RAM 202. In the present embodiment, the management devices 102 and 106 have the same base station information unit in the RAM 302.

  FIG. 26 is a flowchart showing the operation of the wireless terminal according to the present embodiment. The CPU 200 is executed according to a program stored in the ROM 201. FIG. 27 is a flowchart showing the operation of the management apparatus according to the present embodiment. The CPU 300 is executed according to a program stored in the ROM 301. In addition, about the part already demonstrated, description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  When the setting button 304 is pressed (900), the management apparatus 102 notifies the base station 103 of the start of the setting mode (901), and starts scanning for a certain time in order to search for the base station in the setting mode (2700). ). Upon receiving the setting mode start notification, the base station 103 transmits a setting mode notification signal. When the setting button 304 is also pressed in the management apparatus 106, the base station 105 is notified of the start of the setting mode, and the base station 105 transmits a notification signal of the setting mode.

  When the management apparatus 102 detects the notification signal in the setting mode (YES in 2704), the management apparatus 102 stores the detected base station information in the base station information section of the RAM 302 (2702). When the scan ends (YES in 2703), the management apparatus 102 determines the number of base stations in the setting mode (2704).

  If there is one base station in the setting mode (“1” in 2704), the management apparatus 102 waits for a setting request from the wireless terminal, and when receiving the setting request, notifies the wireless parameter of the base station 103. Wireless parameter setting processing is performed (906). When the setting of the radio parameters is completed, the management apparatus notifies the base station of the setting mode end. When receiving the setting mode end notification from the management apparatus, the base station switches to the normal mode. The wireless terminal 100 sets the wireless communication parameters provided from the management apparatus 102 and is connected to the base station 103 that operates in the normal mode to enable data communication. If the base station in the setting mode is 0 (“0” in 2704), it is determined that the setting mode start notification to the base station 103 has not arrived, and the base station 103 is notified again of the setting mode start. (901).

  Also, when a plurality of base stations in the setting mode are detected (2704 “multiple”), the management apparatus 102 broadcasts a duplicate notification via the base station 103. The duplicate notification transmitted from the base station 103 is also sent to the wireless terminal 100. The data is also sent to the base station 105 via the wired LAN, and is also sent from the base station 105 to the management device 106 and the wireless terminal 104.

  When the management apparatus 102 makes a duplicate notification, the management apparatus 102 searches for a management apparatus (903). Then, the information of the searched management device is stored in the management device information unit 305. When the search is completed, the management apparatus 102 checks whether the wireless parameters of the other management apparatuses stored in the management apparatus information unit 305 are the same as the wireless parameters managed by the management apparatus 102 (904). When the wireless parameter of the other management device searched for is the same as the wireless parameter managed by the management device 102 (YES in 905), the management device 102 waits for a setting request from the wireless terminal and detects the setting request. Then, the wireless parameter setting process is performed with the wireless terminal (906). In this case, it is not necessary to end the setting mode because the same wireless parameter is set regardless of which management device the wireless terminal manages.

  When the wireless parameter of the other management device searched for is different from the wireless parameter managed by the management device 102 (NO in 905), the management device 102 issues a setting mode end notification to the base station 103 (908). Then, the management apparatus 102 ends its own setting mode (909). Upon receiving the setting mode end notification, the base station 103 periodically transmits a normal mode notification signal in which the mode area 400 of the notification signal is set to “0”.

  When the setting button 203 is pressed (800), the wireless terminal 100 starts a timer 206 (2600) and monitors whether a duplicate notification is received. The timer 206 is a timer for ensuring a time until the management apparatus 102 scans a base station in the setting mode and transmits a duplication notification in the setting mode.

  Then, the wireless terminal 100 starts scanning for a certain time in order to search for a base station operating in the setting mode (801). After starting the scan, the wireless terminal 100 receives the broadcast signal (setting mode) transmitted from the base station (802), and stores the base station 103 information known from the received broadcast signal in the base station information unit 205 (803). ). When the scanning is completed (YES in 804), the wireless terminal 100 determines whether a duplicate notification has been received (2601).

  When the timer started in 2600 times out without receiving a duplicate notification (NO in 2601, YES in 2602), the wireless terminal 100 refers to the base station information unit 205 stored in 803. And it connects with the base station of setting mode, and sets a wireless communication parameter between management apparatuses (811). When the setting of the radio parameters is completed, the management apparatus notifies the base station of the setting mode end. When receiving the setting mode end notification from the management apparatus, the base station switches to the normal mode. The wireless terminal 100 sets the wireless communication parameters provided from the management apparatus 102 and is connected to the base station 103 that operates in the normal mode to enable data communication.

  If the wireless terminal 100 receives a duplicate notification before the timer 206 activated in 2600 times out (YES in 2601), the wireless terminal 100 resets the timer 206 and activates the timer 206 again (808). The wireless terminal 100 determines whether or not the base station ends the setting mode before the timer 206 started in 808 times out. The end of the setting mode of the base station is not detected (NO in 809), and the timer 206 times out (YES in 810). The wireless terminal 100 connects to the base station operating in the setting mode, transmits a setting request to the management apparatus, and performs wireless parameter setting processing with the management apparatus (811).

  Further, when the wireless terminal 100 detects that the base station that has transmitted the notification signal in the setting mode has transmitted the notification signal in the normal mode before the timer 206 times out (YES in 809), the wireless terminal 100 Is finished (812). The wireless terminal 100 refers to the base station information storage unit 205 to determine that the base station in the setting mode has been switched to the normal mode and the setting mode has ended.

  As described above, according to the present embodiment, it is possible to determine the duplication of the setting mode on the management apparatus side without receiving the duplication notification from the wireless terminal. Therefore, the process of searching for another management apparatus (903) can be started quickly, and the time until the setting mode is completed can be shortened.

  Note that the management apparatus 102 may perform a setting mode start notification (901) when it is determined that there is no base station in the setting mode after scanning (2700 to 2703). In this case, since the base station 103 is operating in the normal mode at the start of scanning, if there is at least one base station in the setting mode as a result of scanning, the setting terminal duplication notification is sent to the wireless terminal 100. (2705). In addition, when the wireless terminal receives the duplicate notification, the wireless terminal ends its own setting mode.

  In this way, when ending the setting mode, the base station does not needlessly transmit the setting mode notification signal.

  Also, the wireless terminal side determines whether or not there are a plurality of setting mode base stations, and when there is a plurality of setting mode base stations and the timer times out while receiving a duplicate notification (2602), The duplicate notification may be performed from the wireless terminal as in the first embodiment.

  By doing in this way, the management apparatus and the base station can end the setting mode more reliably.

  In the above description of each embodiment, a wireless LAN conforming to IEEE 802.11 has been described as an example. However, the present invention is implemented in other wireless media such as wireless USB, MBOA (Multi Band OFDM Alliance), and Bluetooth (registered trademark). May be.

  In the description of the above embodiment, the network identifier, the encryption method, and the encryption key are exemplified as the wireless parameter. However, other information such as the authentication method and the authentication key may be included in the wireless parameter.

  As described above, according to the first to seventh embodiments described above, the management device and the base station can end the setting mode at an early stage.

  Further, even when there are a plurality of setting mode management devices, if the wireless parameters managed by the setting mode management device match, wireless parameter setting can be performed.

  Therefore, it is possible to reduce the occurrence of a situation where an incorrect wireless parameter is set in the wireless terminal.
