Description

  The present invention relates to a communication system, a connection control method, and a connection control program, and more particularly to a communication system, a connection control method, and a connection control program that expand a connection area using a relay device.

  With the rapid spread of mobile terminals such as smartphones in recent years, there is a problem that parents cannot sufficiently manage the use of the Internet from mobile terminals by minors (protected persons).

  In order to cope with this problem, a communication apparatus generally restricts connection from a terminal having a specific MAC (abbreviation of “Media Access Control”) address, or restricts wireless connection of a terminal of a guardian to a time. In many cases, measures are taken such as limiting by band or setting a communication limit to a specific terminal in a specific area.

  However, for example, when a wireless LAN (abbreviation of “Local Area Network”) relay device is used to widen the connection area of the wireless LAN, it is not a wireless LAN parent device that can be easily managed by a guardian. The connection of the portable terminal to the wireless LAN relay device and the use of the Internet become problems.

  With regard to the portable wireless relay device, the technique described in Patent Document 1 stores a connection / disconnection setting table including priorities for connectable wireless LAN base units and wide area wireless communication service base stations in the wireless relay device. To do. Thereby, even if the user of the portable wireless relay device is moving, the wireless LAN terminal can be smoothly reconnected to the wireless LAN base unit desired by the user.

  In the technique described in Patent Document 2, in a radio relay system in a train, when the radio environment with the base station is good, the radio terminal unit connects to the base station and provides a radio service to the mobile terminal. When the wireless environment is bad, a wireless line is connected to another adjacent wireless repeater and a wireless service is provided via the other wireless repeater. For this reason, even if the radio environment of the repeater installed in the train is different for each vehicle, it is possible to efficiently provide a high-quality radio service.

  Regarding control of wireless connection areas, Patent Document 3 discloses security of wireless LAN systems by performing network area management using a waveguide sheet (signal transmission device) that can communicate with a personal computer with weak radio waves. Techniques for improving are described.

  Regarding the MAC address filtering function, the technique described in Patent Document 4 automatically performs a process of updating the MAC address filter information of the wireless access point base unit, thereby eliminating the need for an input operation by an operator. Thereby, the filter information can be updated appropriately and promptly when a wireless LAN terminal is added to or exchanged with the system.

  Referring to FIG. 1, this system includes a communication device 10, a relay device 20 connected to the communication device 10, and at least one terminal 30 to which unique terminal identification information (for example, a MAC address) is assigned. And one or a plurality of external input / output devices 40 connected to the communication apparatus 10.

  The communication device 10 and the relay device 20 are connected by wire or wireless, and can exchange data with each other.

  The terminal 30 is an information processing device that can be connected to either the communication device 10 or the relay device 20 (for example, a mobile terminal such as a smartphone, a personal computer, or the like). Note that the connection between the terminal 30 and the communication device 10 or the relay device 20 may be either a wireless connection or a wired connection. The terminal 30 can input information to the communication device 10 or the relay device 20 and output information of the communication device 10 or the relay device 20 (for example, display on a display screen). Moreover, the user who uses this system using the terminal 30 is classified into a guardian and a person to be protected. Hereinafter, when it is necessary to particularly distinguish and indicate the terminal 30 used by the guardian, it is referred to as “guardian terminal 30”, and when it is necessary to particularly distinguish and indicate the terminal 30 used by the guardian, This will be referred to as “guardian terminal 30”. In the following description, it is assumed that the protected terminal 30 can communicate only with the communication device 10 or the relay device 20.

  The communication device 10 includes a control unit 11, a storage unit 12 including a guardian terminal table 121 and a guardian terminal restriction release permission table 122, and an input / output unit 13.

  The control unit 11 executes a communication control process with the relay device 20, a connection control process based on the terminal identification information assigned to the terminal 30, a communication control process at the time of connection with the terminal 30, and the like. The control unit 11 includes a storage device (not shown) that stores a program, and a processor (not shown) that reads the program into the memory and executes instructions.

  The input / output unit 13 exchanges data with the external input / output device 40. Here, the external input / output device 40 includes a keyboard, a mouse, a button, an NFC (abbreviation of “Near Field Communication”) reading device, and the like for the user to input information to the communication device 10, and the communication device 10 to the user.

The relay device control unit 21 includes a storage device (not shown) that stores a program, and a processor (not shown) that reads the program into the memory and executes instructions.

  FIG. 2 is a diagram illustrating an example of the guardian terminal table 121 in the present embodiment.

  Referring to FIG. 2, the guardian terminal table 121 includes a guardian terminal identification field in which terminal identification information assigned to the guardian terminal 30 is registered in advance.

  For example, referring to the record in the first row in FIG. 2, it can be seen that one of the terminal identification information assigned to the guardian terminal 30 is “T001”.

  FIG. 3 is a diagram illustrating an example of the protected terminal restriction release permission table 122 according to the present embodiment.

  Referring to FIG. 3, protected terminal restriction release permission table 122 includes a protected terminal identification column and a restriction release permission state column. In the protected terminal identification column, terminal identification information assigned to the protected terminal 30 is registered in advance. In the restriction release permission status field, information indicating whether or not the restriction release operation by the protected person using the terminal in the protected terminal identification field is permitted (for example, when the restriction release operation is permitted) "Permit", blank if not permitted) is registered in advance.

  For example, referring to the record in the first line in FIG. 3, “HH001” is registered in the protected terminal identification field, and “permitted” is registered in the restriction release permission state field. That is, it can be seen that the restriction release operation using the protected terminal 30 to which the terminal identification information of HH001 is assigned is permitted.

  FIG. 4 is a diagram illustrating an example of the terminal restriction state table 221 in the present embodiment.

  Referring to FIG. 4, the terminal restriction state table 221 includes a terminal identification field and a restriction state field. In the terminal identification column, terminal identification information assigned to the guardian's terminal 30 is registered in advance. In the restriction status column, information indicating the connection restriction status of the terminal in the terminal identification column to the relay device 20 (for example, “if connection is restricted,“ restricted ”, no connection restriction is applied). In this case, “permitted”) is registered.

  For example, referring to the record in the first line in FIG. 4, “HH001” is registered in the terminal identification field, and “permitted” is registered in the restriction state field. That is, it can be seen that the protected terminal 30 to which the terminal identification information HH001 is assigned is permitted to connect to the relay device 20.

  Next, when registering the information of the protected terminal 30 whose connection to the relay device 20 is restricted to the relay device 20, the control unit 11 of the communication device 10 and the relay device control unit 21 of the relay device 20 The operation will be described with reference to the flowcharts of FIGS.

  FIG. 5 is a flowchart showing the operation of the control unit 11 when registering information of the protected terminal 30 whose connection to the relay device 20 is restricted in the relay device 20.

  Referring to FIG. 5, first, when the terminal 30 is connected to the communication device 10, the control unit 11 acquires terminal identification information of the connected terminal 30 (step S <b> 101).

  Next, the control unit 11 searches the terminal identification column of the guardian terminal table 121 based on the acquired terminal identification information (step S102), and determines whether the terminal identification information is registered (step S103). ).

  When the terminal identification information is registered (in the case of “YES” in step S103), the control unit 11 determines that the terminal is the guardian terminal 30. Then, the control unit 11 sends a confirmation notification as to whether or not to restrict the connection of the protected terminal to the guardian terminal 30. In response to the sent confirmation notification, when there is a reply from the guardian terminal 30 that the connection is restricted, the control unit 11 indicates that the guardian terminal 30 is restricted from connecting to the relay device 20. A restriction notification is transmitted to the relay device 20 (step S104). At this time, the connection restriction notification does not include the terminal identification information of the specific protected terminal 30. Therefore, it represents that the connection to the relay apparatus 20 of all the guardian's terminals 30 is restrict | limited. In addition, in response to the confirmation notification described above, when there is a reply from the guardian terminal 30 that the connection restriction is not performed, the control unit 11 does not transmit the connection restriction notification.

  When the terminal identification information is not registered in the guardian terminal table 121 (in the case of “NO” in step S103), that is, when the connected terminal 30 is the guardian terminal 30, the control unit 11 does nothing particularly. do not do.

  Here, in addition to the processing of the flowchart shown in FIG. 5 described above, when the input unit of the external input / output device 40 is a keyboard or the like, the user can access the setting Web screen of the communication apparatus 10 from the keyboard or the like. It is possible to input an instruction to access and transmit a connection restriction notification and terminal identification information of at least one protected terminal 30 to be included in the connection restriction notification. The instruction to transmit the connection restriction notification and the terminal identification information of the guardian terminal 30 are input by accessing the above setting Web screen using the guardian terminal 30 connected to the communication device 10. May be. Then, the control unit 11 transmits a connection restriction notification including the input terminal identification information of the protected terminal 30 to the relay device 20. In this case, only the protected terminal 30 indicated by the terminal identification information included in the connection restriction notification is restricted from being connected to the relay device 20.

  FIG. 6 is a flowchart illustrating an operation of the relay device control unit 21 when registering information of the protected terminal 30 whose connection to the relay device 20 is restricted in the relay device 20.

  Referring to FIG. 6, first, the relay device control unit 21 receives a connection restriction notification from the communication device 10 (step S201).

  Next, the communication device control unit 21 determines whether or not the terminal identification information of the protected terminal 30 is included in the received connection restriction notification (step S202).

  If the terminal identification information is included in the connection restriction notification (“YES” in step S202), the relay device control unit 21 searches the terminal identification column of the terminal restriction state table 221 based on the terminal identification information. Then, “being restricted” is registered in the restriction status column of the record in which the same terminal identification information is registered (step S203). At the time of registration, when the protected terminal 30 indicated by the terminal identification information is connected to the relay apparatus 20, the relay apparatus control unit 21 disconnects the protected terminal 30.

  When the terminal identification information is not included in the connection restriction notification (in the case of “NO” in step S202), the relay device control unit 21 sets “in the restriction state column of all records registered in the terminal restriction state table 221 to“ "Limiting" is registered (step S205). Further, the relay device control unit 21 disconnects all the protected terminal 30 connected to the relay device 20.

  Next, the relay device control unit 21 transmits to the communication device 10 a connection restriction response including information indicating that the connection restriction setting of the protected terminal 30 has been completed (step S204).

  Thereafter, the relay device control unit 21 refers to the terminal restriction state table 221, and the protected terminal indicated by the terminal identification information registered in the terminal identification field of the record in which “restricted” is registered in the restriction state field 30 is executed to limit connection to the relay device 20. Since a method for restricting connection to a device based on terminal identification information is common (for example, MAC address filtering), detailed description thereof is omitted.

  In this way, when the guardian terminal 30 connects to the communication device 10, it is possible to limit the connection of the guardian terminal 30 to the relay device 20. As a result, the guardian's terminal 30 cannot be connected to the relay device 20 and can be connected only to the communication device 10. For example, it is possible to create an environment in which a guardian who can communicate with the communication device 10 at home can monitor the guardian. In order to prevent the guardian from connecting to the communication device 10 from outside the range that can be monitored by the guardian, the communication speed between the communication device 10 and the guardian terminal 30 is reduced, or the communication device 10 It is also possible to reduce the wireless transmission output to narrow the communication range.

  Next, regarding the operations of the control unit 11 of the communication device 10 and the relay device control unit 21 of the relay device 20 when releasing the connection restriction of the protected terminal 30 whose connection to the relay device 20 is restricted, This will be described with reference to the flowcharts of FIGS.

  FIG. 7 is a flowchart illustrating the operation of the control unit 11 when the user uses the terminal 30 connected to the communication device 10 to release the restriction on the connection of the protected terminal 30 to the relay device 20. It is.

  Referring to FIG. 7, first, the control unit 11 receives a restriction release notification transmission instruction input from the terminal 30 by the user of the terminal 30 connected to the communication device 10 (step S301). Here, the restriction release notification transmission instruction is an instruction for transmitting a restriction release notification from the control unit 11 to the relay device 20. The restriction release notification transmission instruction includes terminal identification information indicating one or more protected terminal 30 whose connection restriction is to be released.

  The restriction release notification transmitted from the control unit 11 to the relay device 20 is a notification indicating that the connection restriction of the protected terminal 30 is to be released. The restriction release notification includes a “release unit” indicating a range in which the restriction should be released on the protected terminal 30 and a “release terminal” indicating terminal identification information of the terminal whose connection restriction is to be released. For example, “Unlock” is set to “All” when the restriction of all the protected terminal 30 is released, and “Individual” when the restriction of the specific protected terminal 30 is released. Is done. When the “release unit” is “individual”, the terminal identification information indicating one or a plurality of protected terminal 30 is set to “release terminal”.

  Next, the control unit 11 determines whether or not the terminal 30 that has transmitted the received restriction release notification transmission instruction is the guardian terminal 30 (step S302). That is, based on the terminal identification information of the terminal 30, the terminal identification column of the guardian terminal table 121 is searched to determine whether or not the terminal identification information is registered.

  When the terminal identification information is registered in the guardian terminal table 121, the control unit 11 determines that the terminal is the guardian terminal 30 ("YES" in step S302). In that case, the control unit 11 sets “individual” as the cancellation unit included in the restriction cancellation notification, and at the cancellation terminal, one or more protected persons included in the limitation cancellation notification transmission instruction received in step S301. Terminal identification information indicating the terminal 30 is set (step S303). Then, the control unit 11 transmits a restriction release notification to the relay device 20 (step S304).

  On the other hand, if the terminal identification information is not registered in the guardian terminal table 121 in step S302, the control unit 11 determines that the terminal is the guardian terminal 30 ("NO" in step S302). In that case, the control unit 11 determines whether or not restriction release by the protected terminal 30 is permitted (step S305). That is, the control unit 11 searches the protected terminal identification column of the protected terminal restriction release permission table 122 based on the terminal identification information indicating the protected terminal 30. Then, it is determined whether or not “permitted” is registered in the restriction release permission state column of the record in which the same terminal identification information is registered.

  If “permitted” is registered in the restriction release permission state column in step S305, the control unit 11 determines that restriction release by the protected terminal 30 is permitted (“YES” in step S305). . In that case, the control unit 11 sets “individual” as the release unit included in the restriction release notification, and sets terminal identification information indicating the protected terminal 30 in the release terminal (step S306). Then, the control unit 11 transmits a restriction release notification to the relay device 20 (step S304).

  When “permitted” is not registered in the restriction release permission state column in step S305, the control unit 11 determines that restriction release by the protected terminal 30 is not permitted (“NO” in step S305). ). In that case, the control unit 11 does nothing in particular.

  FIG. 8 shows the operation of the control unit 11 when the user uses the external input / output device 40 connected to the communication device 10 to release the restriction on the connection of the protected terminal 30 to the relay device 20. It is a flowchart which shows.

  The external input / output device 40 includes one or a plurality of devices for the user to input information (for example, an NFC reading device, a button, a keyboard, etc.). Here, the NFC reading device reads information included in an NFC-compatible IC chip (abbreviation of “Integrated Circuit”) built in the terminal 30 and transmits an input notification to the control unit 11. Here, it is assumed that the input notification from the NFC reading device includes information indicating that the transmission source is the NFC reading device and the terminal identification information of the read protected terminal 30. It is assumed that the circuit is configured so that the input notification when the button is pressed includes information indicating that the transmission source is the button. Furthermore, the input notification from the keyboard includes information indicating that the transmission source is a keyboard and one or a plurality of terminal identification information input from the keyboard.

  Referring to FIG. 8, first, the control unit 11 receives an input notification from the external input / output device 40 (step S401). When the transmission source of the received input notification is an NFC reading device (in the case of “YES” in step S402), the control unit 11 sets “individual” as the cancellation unit included in the limitation cancellation notification and sets it to the cancellation terminal. Then, terminal identification information indicating the protected terminal 30 included in the input notification received in step S401 is set (step S407). Then, the control unit 11 transmits a restriction release notification to the relay device 20 (step S405).

  When the transmission source of the input notification received in step S401 is not an NFC reading device (in the case of “NO” in step S402) and is a button (in the case of “YES” in step S403), the control unit 11 performs the release unit. “All” is set, and nothing is set for the release terminal (step S406). Then, the control unit 11 transmits a restriction release notification to the relay device 20 (step S405).

  Next, when the transmission source of the input notification is a keyboard (in the case of “NO” in step S403), the control unit 11 sets “individual” as the cancellation unit and receives it in the cancellation terminal in step S401. One or a plurality of terminal identification information indicating the protected terminal 30 included in the input notification is set (step S404). Then, the control unit 11 transmits a restriction release notification to the relay device 20 (step S405).

  In the description of FIG. 8, it is assumed that the external input / output device 40 is connected to the NFC reader, button, or keyboard. However, the present invention is not limited to this, and some input notification is sent to the control unit 11. Any device capable of transmitting may be used.

  As described above, as illustrated in FIG. 7 and FIG. 8, the control unit 11 sends the restriction release notification for releasing the connection restriction of the protected terminal 30 whose connection to the relay apparatus 20 is restricted. Send to.

  Next, the operation of the relay device control unit 21 when releasing the restriction on the connection of the protected terminal 30 to the relay device 20 will be described with reference to the flowchart of FIG.

  Referring to FIG. 9, first, the relay device control unit 21 receives a restriction release notification from the communication device 10 (step S501).

  Next, the relay device control unit 21 determines whether or not the release unit included in the received restriction release notification is “all” (step S502). When the release unit included in the received restriction release notification is “all” (in the case of “YES” in step S502), the relay device control unit 21 sets “in the restriction state column of all records in the terminal restriction state table 221 to“ “Allowed” is registered (step S503). Then, the relay device control unit 21 transmits a restriction release response including information indicating that the connection restriction release of the protected terminal 30 has been completed to the communication device 10 (step S504).

  When the cancellation unit included in the received restriction cancellation notification is “individual” (in the case of “NO” in step S502), the relay device control unit 21 is a terminal set as a cancellation terminal included in the limitation cancellation notification The terminal identification column of the terminal restriction state table 221 is searched based on the identification information, and “permitted” is registered in the restriction state column of the record in which the same terminal identification information is registered (step S505). Then, the relay device control unit 21 transmits a restriction release response including information indicating that the connection restriction release of the protected terminal 30 has been completed to the communication device 10 (step S504).

  In this way, in order to cancel the connection restriction of the protected terminal 30 whose connection with the relay apparatus 20 is restricted, the terminal 30 connected to the communication apparatus 10 or the external input / output device 40 It is necessary to perform some input operation on the communication device 10. That is, the person to be protected can be physically moved to an environment where the communication device 10 is located (that is, an environment where the guardian can monitor).

  In the present embodiment, the case where there is one relay device 20 connected to the communication device 10 has been described. However, the embodiment of the present invention is not limited to this, and the plurality of relay devices 20 are connected in series from the communication device 10 or connected in parallel (that is, each relay device 20 is individually connected to the communication device). 10). In such a case, the same connection restriction notification and restriction release notification transmitted from the communication device 10 are transmitted to the relay devices 20 all at once. Then, in each relay device 20, the connection restriction setting process shown in FIG. 6 and the connection restriction releasing process shown in FIG. 9 are executed.

  As described above, in the present embodiment, when a guardian using a mobile terminal or the like uses an external network such as the Internet, the guardian can monitor the guardian (for example, surroundings of the guardian). Or under the supervision of a guardian, etc.).

  The reason is that when the guardian terminal 30 is connected to the communication device 10, the connection of the guardian terminal 30 to the relay device 20 is restricted. This is because the guardian's terminal 30 cannot be connected to the relay device 20 and can be connected only to the communication device 10 (that is, the guardian can monitor).

  In addition, in order for the protected terminal 30 whose connection with the relay device 20 is restricted to release the connection restriction, communication is performed from the terminal 30 connected to the communication device 10 or the external input / output device 40. It is necessary to make some input to the device 10. This is because the person to be protected can be physically moved to the vicinity of the communication device 10 (that is, the environment where the guardian can monitor).

[Second Embodiment]
Next, a second embodiment of the present invention will be described.

  FIG. 10 is a block diagram showing this embodiment.

  The configuration and operation of this embodiment will be described below. In the following, the description of the same components and operations as those in the first embodiment will be omitted.

  Referring to FIG. 10, this system includes a communication device 10, a relay device 60 connected to the communication device 10, and at least one terminal 30 to which unique terminal identification information (for example, a MAC address) is assigned. And one or a plurality of external input / output devices 40 connected to the communication apparatus 10 and at least one sensor 70 connected to the relay apparatus 60.

  The communication device 10 and the relay device 60 are connected by wire or wireless, and can exchange data with each other.

  The relay device 60 includes a relay device control unit 61, a relay device storage unit 62 including a terminal restriction state table 621, and a relay device input unit 63.

  The relay device control unit 61 executes communication control processing with the communication device 10, connection control processing based on terminal identification information assigned to the terminal 30, communication control processing at the time of connection with the terminal 30, and the like. The relay device control unit 61 includes a storage device (not shown) that stores a program, and a processor (not shown) that reads the program into the memory and executes instructions.

  The relay device input unit 63 acquires a signal from the sensor 70 connected by wire or wirelessly. Here, the sensor 70 is, for example, a human sensor that detects a human motion. In response to the sensor state return instruction signal from the relay device input unit 63, the sensor 70 returns a signal indicating “reaction” to the relay device input unit 63 in response to detecting a human operation. If no signal is detected, a signal indicating “no response” is returned. The sensor 70 may be included in the relay device 60.

  The terminal restriction state table 621 has the same configuration as the terminal restriction state table 221 shown in FIG.

  Next, the operation of the relay device control unit 61 when registering information of the protected terminal 30 whose connection to the relay device 60 is restricted to the relay device 60 will be described with reference to the flowchart of FIG. The operation of the communication apparatus 10 at this time is the same as the operation shown in the flowchart of FIG.

  Referring to FIG. 11, first, the relay device control unit 61 receives a connection restriction notification from the communication device 10 (step S601).

  Next, the relay device control unit 61 receives a signal from the sensor 70 via the relay device input unit 63. If the signal received from the sensor 70 is a signal indicating “response” (“YES” in step S602), the relay device control unit 61 receives the connection restriction notification received from the communication device 10 in response to the connection restriction notification. It is determined whether or not the terminal identification information of the guardian terminal is included (step S603). The subsequent operations in steps S604 and S606 are the same as the operations in steps S203 and S205 in the flowchart shown in FIG. Then, the relay device control unit 61 transmits a connection restriction response including information indicating that the connection restriction setting of the protected terminal 30 has been completed to the communication device 10 (step S605).

  On the other hand, when the signal received from the sensor 70 is a signal indicating “no response” in step S602 (in the case of “NO” in step S602), the relay device control unit 61 does not perform the setting for restricting the connection. . Then, the relay apparatus control unit 61 transmits a connection restriction response including information indicating that the connection restriction of the protected terminal 30 has not been set to the communication apparatus 10 (step S605).

  Thereafter, the relay apparatus control unit 61 refers to the terminal restriction state table 621, and shows the protected terminal indicated by the terminal identification information registered in the terminal identification field of the record in which “restricted” is registered in the restriction state field. 30 is executed to limit the connection to the relay device 60.

  In this way, when the signal received from the sensor 70 is a signal indicating “no response”, the relay device control unit 61 determines that there is no protected person to be restricted, and the setting for restricting the connection is performed. Not performed.

  Next, the operation of the relay device control unit 61 when releasing the restriction on the connection of the protected terminal 30 to the relay device 60 will be described with reference to the flowchart of FIG. The operation of the communication apparatus 10 at this time is the same as the operation shown in the flowcharts of FIGS.

  Referring to FIG. 12, first, the relay device control unit 61 receives a restriction release notification from the communication device 10 (step S701).

  Next, the relay device control unit 61 receives a signal from the sensor 70 via the relay device input unit 63. When the signal received from the sensor 70 is a signal indicating “no response” (“YES” in step S702), the relay device control unit 61 is included in the restriction release notification received from the communication device 10. It is determined whether or not the release unit is “all” (step S703). The subsequent operations in step S704 and step S706 are the same as the operations in step S503 and step S505 in the flowchart shown in FIG. Then, the relay device control unit 61 transmits a restriction release response including information indicating that the connection restriction release of the protected terminal 30 has been completed to the communication device 10 (step S705).

  On the other hand, when the signal received from the sensor 70 is a signal indicating “reaction” in step S702 (in the case of “NO” in step S702), the relay device control unit 61 performs setting for releasing the connection restriction. Absent. Then, the relay device control unit 61 transmits a connection restriction response including information indicating that the connection restriction release setting of the protected terminal 30 has not been performed to the communication device 10 (step S705).

  In this way, when the signal received from the sensor 70 is “reactive”, the relay device control unit 61 determines that the protected person to be restricted is in the vicinity of the relay device 60 and releases the connection restriction. Do not set. For example, even when another person who impersonates the person to be protected enters the environment where the communication device 10 is located (that is, the environment in which the person can be monitored) and tries to release the connection restriction of the terminal 30 to be protected, the sensor 70 If the received signal is “Reactive”, the connection restriction is not released.

  In the present embodiment, as in the first embodiment, when a guardian using a mobile terminal or the like uses an external network such as the Internet, the guardian can monitor the guardian. It can be physically moved to a different environment (for example, around the guardian or under the supervision of the guardian).

  The reason for this is that even if another person impersonates a person to be protected and enters the environment where the communication device 10 is present (that is, an environment where the guardian can monitor), the signal received from the sensor 70 is “reactive”. The relay device control unit 61 determines that the protected person to be restricted is in the vicinity of the relay device 60 and does not perform the setting for releasing the connection restriction. For this reason, it is possible to physically move the protected person to be restricted to an environment where the communication device 10 is located.

[Third Embodiment]
Next, a third embodiment including the basic configuration of the first and second embodiments of the present invention will be described.

  FIG. 13 is a block diagram showing this embodiment.

  The configuration and operation of this embodiment will be described below. In the following description, the description of the same components and operations as those in the first and second embodiments is omitted.

  Referring to FIG. 13, the present system includes a communication device 80 and a relay device 90 connected to the communication device 80.

  The communication device 80 and the relay device 90 are connected by wire or wireless, and can exchange data with each other.

  The communication device 80 includes a control unit 81 and a terminal information storage unit 82.

  The control unit 81 executes communication control processing with the relay device 90, connection control processing based on terminal identification information assigned to a terminal (not shown), communication control processing at the time of connection with a terminal (not shown), and the like. Also good.

  The terminal information storage unit 82 may have the same configuration as the guardian terminal table 121 shown in FIG.

  The relay device 90 includes a relay device control unit 91 and a terminal restriction state storage unit 92.

  The relay device control unit 91 executes communication control processing with the communication device 80, connection control processing based on terminal identification information assigned to a terminal (not shown), communication control processing at the time of connection with a terminal (not shown), and the like. May be.

  The terminal restriction state storage unit 92 may have the same configuration as the terminal restriction state table 221 shown in FIG.

  Next, the operation of this system will be described.

  When a first terminal (not shown) whose terminal identification information is registered in the terminal information storage unit 82 is connected to the communication device 80, the control unit 81 restricts the connection of the second terminal to the relay device 90. Is sent to the relay device 90.

  When the relay device control unit 91 receives the connection restriction notification from the communication device 80, the relay device control unit 91 registers “under restriction” in the restriction state column of the record registered in the terminal restriction state storage unit 92.

  As described above, in this embodiment, similarly to the first embodiment, when a guardian who uses the second terminal uses an external network such as the Internet, a guardian who uses the first terminal There is an effect that the protected person can be physically moved to a monitoring environment (for example, around the guardian or under the supervision of the guardian).

  The reason is that the connection of the second terminal to the relay device 90 is restricted when the first terminal is connected to the communication device 80. This is because the second terminal cannot be connected to the relay device 90 and can be connected only to the communication device 80 (that is, a guardian can monitor).
