There are a plurality of standards such as IEEE 802.11ac and Bluetooth (registered trademark) as standards of wireless communication means (wireless communication interface) for performing wireless communication. Generally, a wireless relay device or the like is often used for large-capacity communication, so a standard such as IEEE 802.11ac having a high communication speed is often used. While standards such as IEEE 802.11ac often provide only the function as a handset in a smartphone, standards such as Bluetooth (registered trademark) 5.0 provide the functions of a master and a handset. There are many cases. When permitting the connection of a wireless LAN such as a wireless relay device to another person's portable terminal, connection information such as an SSID (Service Set Identifier) of the wireless LAN and an encryption key is disclosed. However, when wireless LAN SSID and encryption key are disclosed without restriction, connection of many handsets is possible as long as connection setting (connection information) of the wireless relay device connected to the mobile terminal (child unit) is not changed. It is difficult for the administrator to manage connectable slaves.

  There is a method of permitting wireless connection only to a specific slave unit and managing the slave units by setting the MAC (Media Access Control) address of the slave unit permitting the connection to the wireless relay device. However, this method is not easy because the administrator needs to make settings for permitting or disallowing the child device. In addition, when setting permission or non-permission of multiple slave units to multiple wireless relay devices, it is necessary to set permission or non-permission of each slave unit, and the number of administrator must It is not easy because the burden increases and human error increases with it.

  Patent Document 1 discloses a wireless LAN communication that includes an information acquisition unit that acquires a plurality of connection information that can be used to connect to a wireless LAN relay device from the wireless LAN relay device, and a plurality of connection information. Communication including: an information selection unit that selects first connection information that can be used to execute a function; and a communication unit that sets the selected first connection information and performs wireless LAN communication with a wireless LAN relay device A terminal is disclosed. However, Patent Document 1 does not disclose how to limit the communication terminal to which the first connection information is set when the communication terminal performs wireless communication. Therefore, in Patent Document 1, there is a problem that it is not easy because the administrator needs to limit the communication terminal.

The operation of the wireless communication system according to the first embodiment will be described.
FIG. 2 is a sequence diagram illustrating the operation of the wireless communication system according to the first embodiment.
FIG. 2 shows the process until the terminal 14 establishes a connection with the relay apparatus 11 using the first communication interface IF1.

  In this example, it is assumed that the relay device 11, the relay device 12, and the management terminal 13 have already configured the mesh network using the second communication interface IF2.

  As shown in FIG. 2, the terminal 14 acquires the information of the management terminal second communication unit 132 from the QR code (registered trademark), and transmits the terminal second communication to the management terminal second communication unit 132 of the management terminal 13.

  The terminal identification information 14 d is information for identifying the terminal 14, and is information including current position information of the terminal 14. For example, when the user of the terminal 14 is in a hotel, the terminal identification information 14 d is a room number or the like of the hotel.

  The management terminal second communication unit 132 of the management terminal 13 receives the terminal identification information 14d from the terminal 14 using the second communication interface IF2. The management unit 133 of the management terminal 13 permits the connection using the second communication interface IF2 between the terminal 14 and the management terminal 13 when the terminal specification information 14 d matches the terminal specification information registered in advance. The connection between the management terminal 13 and the terminal 14 is established as the management terminal 13 permits the connection with the terminal 14.

  At this time, the management terminal second communication unit 132 of the management terminal 13 may receive the terminal first communication unit identification information 141 d and the use time 14 t in addition to the terminal identification information 14 d. The terminal first communication unit identification information 141 d is information for identifying the terminal first communication unit 141 of the terminal 14. The use time 14t of the terminal 14 is the time when the terminal 14 uses the second communication interface IF2.

  Since the connection using the second communication interface IF2 between the management terminal 13 and the terminal 14 is established, the terminal 14 completes the connection with the management terminal 13 via the second communication interface IF2. Thus, the terminal 14 can participate in the mesh network configured (formed) by the relay device 11, the relay device 12, and the management terminal 13. The terminal 14 is not directly connected to the relay device 11 and the relay device 12, but can communicate with each other using a mesh network.

  The terminal 14 broadcasts the terminal first communication unit identification information 141d for identifying the terminal first communication unit 141 to the relay device 11, the relay device 12, and the management terminal 13 using the second communication interface IF2. (Send.

  The terminal first communication unit identification information 141 d is, for example, information including a MAC (Media Access Control) address of the terminal first communication unit 141 of the terminal 14.

  The management unit 133 of the management terminal 13 stores the received MAC address of the terminal first communication unit 141 (terminal first communication unit identification information 141 d), the terminal identification information 14 d, and the usage time 14 t as the terminal information 14 m. The terminal identification information 14d is information transmitted from the terminal 14 when a connection request using the second communication interface IF2 is made.

  The control unit 113 of the relay device 11 registers the received MAC address of the terminal first communication unit 141 as a MAC address for permitting connection with the relay device first communication unit 111.

  After registration of the MAC address of the terminal first communication unit 141, the relay device second communication unit 112 of the relay device 11 performs connection information IF1d necessary for connection using the first communication interface IF1 with the relay device first communication unit 111. Is transmitted to the terminal 14. That is, the relay apparatus second communication unit 112 transmits the connection information IF 1 d using the mesh network (second communication interface IF 2). The connection information IF 1 d is, for example, information including at least one of an SSID (Service Set Identifier) and an encryption key.

  The control unit 123 of the relay device 12 registers the received MAC address of the terminal first communication unit 141 as a MAC address for permitting connection with the relay device first communication unit 121.

  The terminal 14 uses the connection information IF 1 d necessary for connection with the relay apparatus first communication unit 111, and makes a connection request to the relay apparatus first communication unit 111 of the relay apparatus 11. The terminal 14 transmits the MAC address (terminal first communication unit identification information 141 d) of the terminal first communication unit 141 together at the time of connection request.

  The control unit 113 of the relay device 11 confirms that the MAC address of the terminal first communication unit 141 is permitted to be connected by the first communication interface IF1. That is, the control unit 113 confirms that the MAC address of the terminal first communication unit 141 is registered as the MAC address for permitting connection with the relay device first communication unit 111.

  The control unit 113 permits the connection with the terminal 14 when the received MAC address of the terminal first communication unit 141 matches the MAC address registered as the one for permitting the connection.

  The terminal 14 completes the connection with the relay apparatus 11 using the first communication interface IF1.

  After that, even when the terminal 14 is not connected to the management terminal 13 using the second communication interface IF2, the terminal 14 can be connected to the relay apparatus 11 using the first communication interface IF1.

FIG. 3 is a sequence diagram illustrating the operation of the wireless communication system according to the first embodiment.
FIG. 3 shows the process until the connection using the first communication interface IF1 between the terminal 14 and the relay apparatus 11 becomes impossible by the management terminal 13.

  In this example, it is assumed that the connection between the terminal 14 and the relay device 11 has already been completed using the first communication interface IF1.

  As shown in FIG. 3, the management unit 133 of the management terminal 13 deletes the terminal information 14m of the terminal 14 when the terminal 14 is not connected using the second communication interface IF2 after the predetermined use time 14th has passed. Do. The terminal information 14m includes registered terminal first communication unit identification information 141d, terminal identification information 14d, and use time 14t.

  The management terminal 13 does not permit connection using the second communication interface IF2 with the terminal 14. That is, by deleting the terminal information 14 m of the terminal 14, the management unit 133 of the management terminal 13 deletes the connection permission with the terminal second communication unit 142 of the management terminal second communication unit 132.

  As a result, the terminal 14 can not connect to the management terminal 13 using the second communication interface IF2.

  The management unit 133 of the management terminal 13 broadcasts that the terminal information 14m including the MAC address of the terminal first communication unit 141 has been deleted, to the relay apparatus 11 and the relay apparatus 12 using the second communication interface IF2. . Then, the management unit 133 of the management terminal 13 notifies that the terminal information 14m including the MAC address of the terminal first communication unit 141 is deleted.

  When the management terminal 13 does not permit the connection using the second communication interface IF2, the control unit 113 of the relay device 11 deletes the registered terminal first communication unit identification information 141d. That is, the control unit 113 of the relay device 11 deletes the received MAC address of the terminal first communication unit 141 from the MAC address that permits connection with the relay device first communication unit 111.

  The control unit 123 of the relay device 12 deletes the received MAC address of the terminal first communication unit 141 from the MAC address that permits connection with the relay device first communication unit 121.

  When the terminal 14 is connected, the relay device 11 is no longer a MAC address that permits the terminal first communication unit 141 to connect to the relay device first communication unit 111, so the terminal using the first communication interface IF1 The connection with the first communication unit 141 is disconnected.

  As a result, the terminal 14 can not connect to the relay device 11 using the first communication interface IF1.

FIG. 4 is a sequence diagram illustrating the operation of the wireless communication system according to the first embodiment.
FIG. 4 shows the case where the terminal 14 does not perform control to disable connection after the use is completed.

  In this example, it is assumed that the connection between the terminal 14 and the relay device 11 has already been completed using the first communication interface IF1.

  As shown in FIG. 4, the management unit 133 of the management terminal 13 compares the usage time 14t of the terminal information 14m with the predetermined usage time 14th. The management unit 133 of the management terminal 13 checks whether the terminal 14 is connected to the management terminal 13 using the second communication interface IF2 after the predetermined use time 14th has elapsed.

  The management unit 133 of the management terminal 13 deletes the terminal information 14m of the terminal 14 when the terminal 14 is not connected to the terminal 14 using the second communication interface IF2 after the predetermined use time 14th has elapsed.

  Along with the deletion of the terminal information 14m of the terminal 14, the management unit 133 of the management terminal 13 deletes the connection permission between the management terminal second communication unit 132 and the terminal second communication unit 142.

  The management unit 133 of the management terminal 13 broadcasts that the terminal information 14m including the MAC address of the terminal first communication unit 141 has been deleted, using the relay device 11, the relay device 12, and the second communication interface IF2. Also, the management unit 133 of the management terminal 13 notifies that the terminal information 14m including the MAC address of the terminal first communication unit 141 is deleted.

  The control unit 113 of the relay device 11 deletes the received MAC address of the terminal first communication unit 141 from the MAC address that permits connection with the relay device first communication unit 111.

  The control unit 123 of the relay device 12 deletes the received MAC address of the terminal first communication unit 141 from the MAC address that permits connection with the relay device first communication unit 121.

  As a result, the terminal 14 can not connect to the relay device 11 using the first communication interface IF1.

  In the wireless communication system 10 according to the first embodiment, when the terminal 14 connects with the management terminal 13 using the second communication interface IF2, mutual communication with the relay device 11 becomes possible, and mutual communication with the relay device 12 Communication is possible. Then, the MAC address of the terminal first communication unit 141 received from the terminal 14 using the second communication interface IF2 is a MAC for which the control unit 113 of the relay device 11 permits connection with the relay device first communication unit 111. Set as an address. As a result, there is no need for the administrator to set, in the relay apparatus 11, a MAC address for permitting connection with the relay apparatus first communication unit 111. Similarly to the relay device 11, it is not necessary for the administrator to set, in the relay device 12, a MAC address for permitting connection with the relay device first communication unit 121 for the relay device 12.

  As a result, there is no need for the administrator to set the MAC address (of the terminal) for permitting connection to each of the relay apparatus 11 and the relay apparatus 12.

  Further, in the radio communication system 10 according to the first embodiment, the management unit 133 of the management terminal 13 deletes the terminal information 14m of the terminal 14 intentionally or by use time. The control unit 113 of the relay device 11 acquires a notification that the terminal information 14m has been deleted, and deletes the MAC address of the terminal first communication unit 141 from the MAC address that permits connection with the relay device first communication unit 111. . The relay device 12 is also similar to the relay device 11.

  As a result, there is no need for the administrator to delete the MAC address (of the terminal) from the MAC addresses for which connection is permitted for each of the relay device 11 and the relay device 12.

  As a result, when the terminal performs wireless communication, it is possible to provide a wireless communication system and method capable of easily setting wireless connection permission for wireless communication and connection information used in wireless communication for wireless communication.

  Further, in the radio communication system 10 according to the first embodiment, even when a relay apparatus is newly added instead of the terminal 14, the relay apparatus is added in the same manner as the management terminal 13 adds the terminal 14. be able to. Also, the existing relay device 11 or 12 may have the function of the management terminal 13. By doing this, when newly adding a relay device, the relay device can be easily added by connecting to any of the relay device 11, the relay device 12 and the management terminal 13.

  In addition, by using a relay terminal that relays the management terminal 13, a relay device can be easily added even outside the detection range of the second communication interface IF2 of the management terminal 13.

  In addition, since the relay terminal, the management terminal 13 and the terminal 14 do not need to have the function as the master of the first communication interface IF1, cost reduction can be realized.

  Further, communication between the relay device 11, the relay device 12, the management terminal 13 and the terminal 14 is performed in a local network called a mesh network formed by the second communication interface IF 2. Therefore, the relay apparatus 11, the relay apparatus 12, the management terminal 13, and the terminal 14 can be easily installed as compared with the case of using a global address.

The features of the present disclosure will now be described.
The wireless communication system 10 according to the first embodiment includes a relay device 11, a relay device 12, a terminal 14 (child device terminal), and a management terminal 13, for example, a mesh network (network 15) using Bluetooth (registered trademark). Form. The relay device 11, the relay device 12, or the management terminal 13 permits connection to the wireless LAN (the first communication interface IF1) only to the terminal newly connected to the mesh network. Thus, the relay device and the terminal connected to the wireless LAN can be easily managed.

  The wireless communication system 10 according to the first embodiment uses the second communication interface IF2 to form a mesh network. Thus, the management terminal 13 having the management terminal first communication unit 131 that does not have the function of the slave unit can be disposed in the middle of the network. Since the management terminal 13 does not have the function of a slave, low cost can be realized.

  The management terminal 13 can disconnect the connection of the terminal 14 to the mesh network. When the connection of the terminal 14 to the mesh network is disconnected, the relay device 11 connects from the management terminal 13 to the relay device 11 by deleting the connection permission with the relay device first communication unit 111 from the terminal 14. It can manage the terminal. The same applies to the relay device 12. Thus, it is possible to easily manage relay devices and terminals.

By deleting the terminal information 14m of the terminal 14 from the management unit 133 of the management terminal 13, the connection between the management terminal 13 and the second communication interface IF2 of the terminal 14 is released.

The management unit 133 of the management terminal 13 permits the MAC address of the terminal first communication unit 141 stored in the management terminal 13 to the wireless LAN connection to the relay device 11 and the relay device 12 in the mesh network. Broadcast to remove from the address. The wireless LAN is, for example, the first communication interface IF1 in the first embodiment. As a result, the terminal 14 can not connect to the relay device 11 and the relay device 12. It is possible to easily manage relay devices and terminals.

  When the wireless communication system 10 according to the first embodiment adds a relay device newly, the wireless communication system 10 is connected to any of the relay device 11, the relay device 12 or the management terminal 13 using the second communication interface IF2. Then, the management terminal 13 can manage the relay apparatus. At this time, the relay device to be newly added does not have to be directly connected to the management terminal 13. A relay device disposed at a distance not directly reached by the second communication interface IF2 of the management terminal 13 by arranging a terminal for relaying these between the relay device to be newly added and the management terminal 13 Can manage.

  In the first embodiment, Bluetooth (registered trademark) having a low communication speed and low power consumption has been exemplified as the second communication interface constituting the mesh network, but the present invention is not limited to this. Also, as the first communication interface, a wireless LAN such as the IEEE 802.11ac standard, which has a high communication speed and a large power consumption, has been exemplified, but the present invention is not limited thereto.

That is, the relay device second communication unit 112, the relay device second communication unit 122, and the management terminal second communication unit 132 form a mesh network using the second communication interface IF2.

  The terminal 14 obtains permission of connection using the first communication interface IF1 with the relay device 11 by connecting to the mesh network using the relay device 11 and the second communication interface IF2.

The operation of the radio communication system according to the second embodiment will be described.
FIG. 6 is a sequence diagram illustrating the operation of the wireless communication system according to the second embodiment.
