FIG. 3 is a diagram illustrating a display unit when the installation position of the access point device 12 is displayed.

  First, an outline of the relay device system 1 will be described. As illustrated in FIG. 1, the relay device system 1 includes a plurality of access point devices (relay devices) 12 and a management server 16 that manages the access point device 12. Although only three access point devices 12 are shown in FIG. 1, it is assumed that the relay device system 1 is actually composed of more access point devices 12. Since the plurality of access point apparatuses 12 have substantially the same configuration except for set information, only one access point apparatus 12 will be described below as a representative.

  Hereinafter, the access point device 12 will be described.

  The access point device 12 is installed by a provider (hereinafter, a line provider) that provides a service that provides Internet connection. The line provider arranges the access point device 12 at, for example, a station or a restaurant. A person (user) in a station or a restaurant can connect his / her communication terminal 11 such as a smartphone or a notebook computer to the Internet 14 via the access point device 12. Note that the installation location of the access point device 12 is not limited to a building, and the access point device 12 may be installed on a moving body such as an automobile. For example, the line provider can provide a service to users around the car during the sale of the product by installing the access point device 12 in the car that performs mobile sales.

  As illustrated in FIG. 1, the access point device 12 includes a device ID storage unit 21, a GNSS receiver 22, a height detection unit 23, a connection relay unit 24, and a location information communication unit 25.

  The connection relay unit 24 performs processing for connecting the communication terminal 11 to the Internet 14 (processing for relaying communication of the communication terminal 11). As shown in FIG. 1, the connection relay unit 24 includes a terminal side communication unit 24a and a WAN side communication unit 24b.

  The terminal-side communication unit 24a performs processing for connecting the communication terminal 11 to the access point device 12 wirelessly. Specifically, an SSID and a password are set in the access point device 12. The line provider may change the SSID and password for each access point device 12 or may set the same SSID and password for some of the access point devices 12. Further, the user can obtain the SSID and password set by the line provider by making a contract with the line provider. Thus, the user can connect the communication terminal 11 to the access point device 12 by operating the communication terminal 11 and inputting the SSID and password obtained from the line provider.

  The WAN side communication unit 24b is connected to the Internet 14 via a router (not shown). Note that the Internet 14 can use not only a wired type but also a wireless type (such as a mobile phone network, WiMAX (registered trademark)). With the above configuration, the connection relay unit 24 can connect the communication terminal 11 to the Internet 14. Accordingly, the user can obtain predetermined information by accessing, for example, the Web server 15 via the access point device 12.

  The device ID storage unit 21 stores the device ID of the access point device 12. The device ID is uniquely determined for each access point device 12. The management server 16 can identify the access point device 12 by this device ID.

  The GNSS receiver 22 receives the positioning signal from the GNSS satellite by the GNSS antenna and performs calculation, thereby calculating the longitude and latitude of the access point device 12 (specifically, the longitude and latitude of the GNSS antenna, hereinafter referred to as longitude / latitude information). ) The GNSS receiver 22 can obtain not only longitude / latitude information but also altitude. In addition, as GNSS, specifically, GPS, GALILEO, GLONASS, and the like can be used.

  The height detector 23 is configured to be able to measure the ambient atmospheric pressure. The height detector 23 obtains height information indicating the altitude of the access point device 12 based on the measured atmospheric pressure and the altitude detected by the GNSS receiver 22. In the following description, the longitude / latitude information detected by the GNSS receiver 22 and the altitude information detected by the height detection unit 23 may be collectively referred to as “position information”.

  The location information communication unit 25 transmits the location information to the management server 16 together with the device ID stored in the device ID storage unit 21.

  Next, the management server 16 will be described. As illustrated in FIG. 1, the management server 16 includes a communication unit (reception unit) 31, a storage unit 32, a control unit 33, and a display unit 34.

  The communication unit 31 is configured to be able to transmit / receive predetermined data to / from the access point device 12. For example, the communication unit 31 receives position information from the access point device 12 or transmits an SSID and password to be set to the access point device 12.

  The storage unit 32 stores a management database 32 a that includes information related to the access point device 12. As shown in FIG. 2, the management database 32a describes items of device ID, last update time, location information, SSID, and password. The device ID is a device ID stored in the device ID storage unit 21 of each access point device 12. The last update time indicates the time when the location information, SSID, etc. of each access point device 12 was last updated. The position information is detected by the GNSS receiver 22 and the height detection unit 23 of each access point device 12, and the position information transmitted by the position information communication unit 25 is described. In the SSID and password, the SSID and password set in the access point device 12 are described.

  The control unit 33 performs overall control of the management server 16. In addition, the control unit 33 of the present embodiment performs position related control that is control based on the position information of the management database 32a. As position-related control, a video (see FIG. 3) that displays the position of the access point device 12 on a map is created and displayed, or notification is made when the positions of the access point devices 12 are close to each other. The control to be performed can be considered (details will be described later).

  The display unit 34 displays, for example, the contents of the management database 32a, or displays the video created by the control unit 33 (video displaying the position of the access point device 12 on the map) (see FIG. 3). . In FIG. 3, the position of the access point device 12 is represented by device position display marks 51 a to 51 d. By displaying the access point device 12 on the map in this way, it is possible to easily find out the deviation of the installation position of the access point device 12 or the like. Therefore, when the access point apparatus 12 is newly installed, the access point apparatus 12 can be installed at an ideal position.

  Next, the flow of processing performed by the access point device 12 and the management server 16 will be described with reference to FIGS. FIG. 4 is a sequence diagram showing a flow of processing performed by the relay apparatus system.

  First, the flow when the position information of the management database 32a is updated will be described. The GNSS receiver 22 and the height detection unit 23 of the access point device 12 detect position information at a predetermined timing (for example, every few seconds). The access point device 12 transmits the latest position information detected by the GNSS receiver 22 and the height detection unit 23 together with the device ID to the management server 16 (sequence number 1). As a timing at which the access point device 12 transmits the position information, for example, immediately after the access point device 12 is activated, there is a notification from the management server 16 every predetermined time.

  The management server 16 that has received the location information from the access point device 12 updates the management database 32a by replacing the location information corresponding to the received device ID with the latest location information (sequence number 2).

  Next, a flow when the SSID and password set in the access point device 12 are changed will be described. When the setting is changed by the line provider (sequence number 3), the management server 16 transmits the changed SSID and password to the access point device 12 and instructs to change the SSID and password (sequence number 4). .

  The access point device 12 that has received the SSID and password change instruction changes the SSID and password settings based on the content transmitted from the management server 16 (sequence number 5). Then, the access point device 12 transmits information indicating that the change has been completed to the management server 16 (sequence number 6).

  Receiving completion of the change of the SSID and password, the management server 16 updates the management database 32a with the changed SSID and password (sequence number 7).

  Next, the flow of processing performed when the positions of the access point devices 12 are close to each other will be described.

  The control unit 33 of the management server 16 can grasp the position of each access point device 12 based on the management database 32a. Therefore, the control unit 33 can detect that the positions of the access point devices 12 are closer than a predetermined threshold. In the present embodiment, since the height information is included in the position information, the latitude / longitude information is the same but the height information is different (when a plurality of access point devices 12 are arranged in a building or the like). Even so, the actual distance between the relay devices can be grasped based on the height information.

  Hereinafter, as shown in FIG. 3, it is assumed that the access point device 12 indicated by the device position display mark 51b moves and approaches the access point device 12 indicated by the device position display mark 51c. In this case, the management server 16 receives the position information from the access point device 12 indicated by the device position display mark 51c, and updates the management database 32a (sequence number 8). Thereby, the control part 33 detects that the distance between the access point apparatuses 12 became near the predetermined threshold value (sequence number 9).

  As a result, the control unit 33 notifies the line provider or the like that the position of the access point device 12 is close (sequence number 10, position related control). This notification may be performed by e-mail, notification sound, or the like, or may be performed by changing the display form of the display unit 34. As a specific example of changing the display form, as shown in FIG. 3B, a configuration in which the access point device 12 with a close position is highlighted is conceivable.

  Then, for example, after a predetermined time has passed since the notification, the control unit 33 instructs the two access point devices 12 that are close to each other to adjust the radio waves for connecting to the communication terminal 11 (sequence number 11, position related). control).

  Receiving this instruction, the access point device 12 adjusts the radio wave (sequence number 12). Specifically, the radio wave adjustment performed by the access point device 12 includes changing the occupied band (for example, changing from 40 MHz to 20 MHz), reducing the output (intensity) of the radio wave, and changing the channel of the radio wave. It can be mentioned as an example. By performing the above processing, it is possible to prevent radio wave interference between the access point devices 12, and thus it is possible to prevent a decrease in communication speed and unstable connection.

  Next, a modification of the above embodiment will be described. In the following description of the modified examples, the same or similar configurations as those of the above embodiment are denoted by the same reference numerals as those of the above embodiment, and description thereof is omitted. FIG. 5 is a block diagram showing a relay device system 1a according to a modification.

  In the above embodiment, the relay device system 1 including the management server 16 has been described. However, the relay device system 1a according to the present modification has a configuration that does not include the management server 16. Therefore, in this modification, the location information communication unit 25 of the access point device 12 exchanges location information as necessary. Therefore, the position information communication unit 25 according to the present modification not only transmits the position information but also performs a process of receiving the position information.

  Further, the access point device 12 of this modification includes a control unit 26 and a display unit 27 in addition to the configuration of the access point device 12 of the above embodiment. The control unit 26 performs position related control similarly to the control unit 33. Similar to the display unit 34, the display unit 27 displays the video created by the control unit 26.

  In addition, in this modification, when the position information of another access point apparatus 12 is needed without creating a database, the position information is received from the access point apparatus 12. Therefore, in the above embodiment, the relay device system 1 cannot be used only when a failure occurs in the management server 16, whereas in this modification, even if a failure occurs in a certain access point device 12, The relay device system 1 can be maintained by another access point device 12. Therefore, the relay apparatus system 1a according to the present modification realizes a configuration that is resistant to failures.

  As described above, the relay device system 1 includes a plurality of access point devices 12, and includes a connection relay unit 24, a GNSS receiver 22, a position information communication unit 25, and a control unit 33. . The connection relay unit 24 connects the communication terminal 11 to the Internet. The GNSS receiver 22 obtains position information of the access point device 12 based on a signal from a GNSS satellite. The position information communication unit 25 transmits the position information obtained by the GNSS receiver 22. Based on the position information received from the position information communication unit 25, the control unit 33 performs position-related control that is control based on the position information of the plurality of access point devices 12. In the present embodiment, the connection relay unit 24, the GNSS receiver 22, and the location information communication unit 25 are provided in the access point device 12, and the control unit 33 is provided in the management server 16.

  Thereby, based on the position information of the plurality of access point devices 12, the position of each access point device 12 is displayed on the map, or when the distance between the access point devices 12 is close, notification to that effect Can do. Therefore, a provider who provides Internet connection can install a new relay device while considering the position of the installed access point device 12. In addition, since the access point device 12 includes the GNSS receiver 22, it is not necessary to manually set position information even when the installation location of the access point device 12 is changed. Can do.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  A storage unit having a database of position information, a control unit that performs position-related control, and a display unit that displays the position of the access point device 12 may be arranged on the access point device 12 side or arranged on the management server 16 side. May be. Moreover, the combination is also arbitrary.

  In the above embodiment, when the management server 16 determines that the distance between the two access point devices 12 is short, control is performed to adjust the radio wave. However, the radio wave adjustment can be performed based on appropriate conditions as well as when the distance between the two access point devices 12 is short.

  The information for detecting the height information is not limited to the example described in the above embodiment. For example, the GNSS receiver 22 or the height detection unit 23 may be configured to obtain height information independently. Moreover, the structure which the GNSS receiver 22 calculates | requires height information based on the height which the height detection part 23 detected may be sufficient.

  The position related control is not limited to the above example as long as it is based on the position information.

  In the above-described embodiment and modification, an example in which an access point device is used as a relay device has been described. However, a wireless or wired router may be used as the relay device. Further, the number of relay devices constituting the relay device system 1 is also arbitrary.
