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 for expanding a connection area by using a relay device.

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

In order to deal with this problem, communication devices generally limit the connection from the terminal of a specific MAC (abbreviation of "Media Access Control") address, or make the wireless connection of the protected person's terminal time. In many cases, measures are taken such as restricting by band or setting communication restriction on a specific terminal in a specific area.

However, for example, when the wireless LAN connection area is expanded by using a wireless LAN (abbreviation of "Local Area Network") relay device, it is not protected by a wireless LAN base unit that is easy for parents to manage. The problem is the connection of mobile terminals to wireless LAN relay devices and the use of the Internet, which are difficult to monitor.

Regarding the portable wireless relay device, in the technique described in Patent Document 1, a connection / disconnection setting table including a priority for a connectable wireless LAN base unit and a wide area wireless communication service base station is stored in the wireless relay device. do. As a result, 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, when the wireless environment with the base station is good in the wireless relay system in the train, the wireless terminal unit connects to the base station and provides the wireless service to the mobile terminal. When the wireless environment is poor, a wireless line is connected to another adjacent wireless repeater, and wireless service is provided via the other wireless repeater. Therefore, even if the wireless environment of the repeater installed in the train differs for each vehicle, it is possible to efficiently provide high-quality wireless service.

Further, regarding the control of the wireless connection area, Patent Document 3 describes the security of the wireless LAN system by managing the area of the network using a waveguide (signal transmission device) capable of communicating with the personal computer by weak radio waves. Techniques for improving the above are described.

Further, regarding the MAC address filtering function, in the technique described in Patent Document 4, the process of updating the MAC address filter information of the wireless access point master unit is automatically performed, so that the input work by the operator operation becomes unnecessary. As a result, the filter information can be updated appropriately and promptly when the wireless LAN terminal is added to or replaced with the system.

The communication device 10 and the relay device 20 are connected by wire or wirelessly, and data can be exchanged 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). 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 the information of the communication device 10 or the relay device 20 (for example, display on a display screen). Further, the user who uses this system by using the terminal 30 is divided into a guardian and a protected person. Hereinafter, when it is necessary to particularly distinguish the terminal 30 used by the guardian, it is referred to as "guardian terminal 30", and when it is necessary to particularly distinguish the terminal 30 used by the protected person, "subject". It is called "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 protected terminal restriction release permission table 122, and an input / output unit 13.

The control unit 11 executes communication control processing with the relay device 20, connection control processing based on the terminal identification information assigned to the terminal 30, communication control processing at the time of connection with the terminal 30, and the like. The control unit 11 includes a storage device (not shown) for storing a program and a processor (not shown) for reading the program into a memory and executing an instruction.

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 for the user to input information to the communication device 10, an NFC (abbreviation of "Near Field Communication") reading device, and the communication device 10 to the user.

FIG. 2 is a diagram showing 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 the terminal identification information assigned to the guardian terminal 30 is registered in advance in advance.

For example, referring to the record in the first line of 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 showing an example of the protected terminal restriction release permission table 122 in the present embodiment.

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

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

FIG. 4 is a diagram showing an example of the terminal restriction state table 221 according to the present embodiment.

Referring to FIG. 4, the terminal restricted state table 221 includes a terminal identification column and a restricted state column. In the terminal identification field, the terminal identification information assigned to the protected terminal 30 is registered in advance in advance. In the restricted status column, information indicating the status of connection restriction of the terminal in the terminal identification column to the relay device 20 (for example, "restricted" when connection restriction is applied, connection restriction is not applied". In that case, "permitted") is registered.

For example, referring to the record in the first line of FIG. 4, "HH001" is registered in the terminal identification column, and "permitted" is registered in the restricted state column. 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. 5 and 6.

FIG. 5 is a flowchart showing the operation of the control unit 11 when registering the 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 the terminal identification information of the connected terminal 30 (step S101).

Next, the control unit 11 searches the terminal identification field of the guardian terminal table 121 based on the acquired terminal identification information (step S102), and determines whether or not the terminal identification information is registered (step S103). ).

When the terminal identification information is registered (when "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 notice to the guardian terminal 30 as to whether or not to restrict the connection of the protected terminal. When the guardian terminal 30 responds to the sent confirmation notification to the effect that the connection is restricted, the control unit 11 indicates that the connection of the protected terminal 30 to the relay device 20 is restricted. The 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 means that the connection of all the protected terminals 30 to the relay device 20 is restricted. Further, when the guardian terminal 30 replies that the connection restriction is not performed in response to the above confirmation notification, the control unit 11 does not transmit the connection restriction notification.

Further, when the terminal identification information is not registered in the guardian terminal table 121 (when "NO" in step S103), that is, when the connected terminal 30 is the protected terminal 30, the control unit 11 does nothing in particular. do not.

Here, apart from the processing of the flowchart shown in FIG. 5 described above, when the input means of the external input / output device 40 is a keyboard or the like, the user can display the setting Web screen of the communication device 10 from the keyboard or the like. It is possible to input an instruction to access and send 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 send the connection restriction notification and the terminal identification information of the protected terminal 30 are input by accessing the above setting Web screen using the guardian terminal 30 connected to the communication device 10. You may. Then, the control unit 11 transmits the input connection restriction notification including the terminal identification information of the protected terminal 30 to the relay device 20. In this case, it means that the connection to the relay device 20 is restricted only to the protected terminal 30 indicated by the terminal identification information included in the connection restriction notification.

FIG. 6 is a flowchart showing the operation of the relay device control unit 21 when registering the 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 the connection restriction notification from the communication device 10 (step S201).

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

When the connection restriction notification includes the terminal identification information (when "YES" in step S202), the relay device control unit 21 searches the terminal identification field of the terminal restriction status table 221 based on the terminal identification information. , Register "restricted" in the restricted status column of the record in which the same terminal identification information is registered (step S203). Further, at the time of registration, the relay device control unit 21 disconnects the protected person terminal 30 when the protected person terminal 30 indicated by the terminal identification information is connected to the relay device 20.

When the terminal identification information is not included in the connection restriction notification (when "NO" is set in step S202), the relay device control unit 21 puts "" in the restriction status column of all the records registered in the terminal restriction status table 221. "Restricted" is registered (step S205). Further, the relay device control unit 21 disconnects all the protected terminals 30 connected to the relay device 20.

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

After that, the relay device control unit 21 refers to the terminal restriction status table 221 and indicates the protected terminal indicated by the terminal identification information registered in the terminal identification column of the record in which "restricted" is registered in the restriction status column. The connection restriction process of 30 to the relay device 20 is executed. Since the method of restricting the connection to the device based on the terminal identification information is common (for example, MAC address filtering), detailed description thereof will be omitted.

By connecting the guardian terminal 30 to the communication device 10 in this way, it is possible to limit the connection of the protected terminal 30 to the relay device 20. As a result, the protected terminal 30 cannot be connected to the relay device 20, but can be connected only to the communication device 10. For example, a guardian who is in a place where he / she can communicate with the communication device 10 in his / her home can create an environment in which the protected person can be monitored. In addition, in order to prevent the protected person from connecting to the communication device 10 from outside the range that can be monitored by the guardian, the speed of communication between the communication device 10 and the protected person terminal 30 may be reduced, or the communication device 10 may be used. It is also possible to narrow the communication range by reducing the wireless transmission output of.

Next, regarding the operation of the control unit 11 of the communication device 10 and the relay device control unit 21 of the relay device 20 when the connection restriction of the protected terminal 30 whose connection to the relay device 20 is restricted is released. This will be described with reference to the flowcharts of FIGS. 7 to 9.

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

Referring to FIG. 7, first, the control unit 11 receives the 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 the 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 terminals 30 for which connection restrictions should 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 released. The restriction release notification includes a "release unit" indicating the range in which the restriction should be released for the protected terminal 30, and a "release terminal" indicating the terminal identification information of the terminal from which the connection restriction is released. For example, in the "release unit", "all" is set when the restrictions on all the protected terminals 30 are released, and "individual" is set when the restrictions on the specific protected terminals 30 are released. Will be done. When the "release unit" is "individual", the terminal identification information indicating one or more protected terminals 30 is set in the "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 field of the guardian terminal table 121 is searched, and it is determined 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 release unit included in the restriction release notification, and at the release terminal, one or a plurality of protected persons included in the restriction release notification transmission instruction received in step S301. The 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 protected terminal 30 (“NO” in step S302). In that case, the control unit 11 determines whether or not the 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 "permission" is registered in the restriction release permission status column of the record in which the same terminal identification information is registered.

When "permission" is registered in the restriction release permission status column in step S305, the control unit 11 determines that the 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 the 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).

If "permission" is not registered in the restriction release permission status column in step S305, the control unit 11 determines that the 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 connection restriction 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 more devices for the user to input information (for example, an NFC reader, a button, a keyboard, etc.). Here, the NFC reading device reads the information contained in the NFC-compatible IC chip (abbreviation of "Integrated Circuit") built in the terminal 30 and transmits the 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 protected person terminal 30 that has been read. Then, 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. Further, the input notification from the keyboard shall include information indicating that the source is the keyboard and one or more 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 source of the received input notification is an NFC reader (when "YES" in step S402), the control unit 11 sets "individual" as the release unit included in the restriction release notification, and sets the release terminal to the release terminal. , The 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).

If the source of the input notification received in step S401 is not an NFC reader (when "NO" in step S402) but a button (when "YES" in step S403), the control unit 11 is set to the release unit. “All” is set, and nothing is set in 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 source of the input notification is a keyboard (when "NO" is set in step S403), the control unit 11 sets "individual" as the release unit and receives it at the release 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 NFC reader, the button, or the keyboard is connected to the external input / output device 40, but the present invention is not limited to these, and some input notification is sent to the control unit 11. Any device that can transmit is sufficient.

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

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

Referring to FIG. 9, first, the relay device control unit 21 receives the 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" (when "YES" in step S502), the relay device control unit 21 puts "" in the restriction status column of all records in the terminal restriction status table 221. "Allowed" is registered (step S503). Then, the relay device control unit 21 transmits a restriction release response including information that the connection restriction release of the protected terminal 30 is completed to the communication device 10 (step S504).

When the release unit included in the received restriction release notification is "individual" (when "NO" in step S502), the relay device control unit 21 is a terminal set as the release terminal included in the restriction release notification. The terminal identification field of the terminal restriction status table 221 is searched based on the identification information, and "permitted" is registered in the restriction status 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 that the connection restriction release of the protected terminal 30 is completed to the communication device 10 (step S504).

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

In this embodiment, the case where the number of relay devices 20 connected to the communication device 10 is one has been described. However, the embodiment of the present invention is not limited to this, and a 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). (When connected to 10) may be. In such a case, the connection restriction notification and the restriction release notification transmitted from the communication device 10 have the same contents and are simultaneously transmitted to each relay device 20. Then, each relay device 20 executes the connection restriction setting process shown in FIG. 6 and the connection restriction release process shown in FIG.

As described above, in the present embodiment, when a protected person using a mobile terminal or the like uses an external network such as the Internet, the guardian can monitor the protected person (for example, around the guardian). , Or under the supervision of a guardian, etc.) has the effect of being able to be physically moved.

The reason is that the guardian terminal 30 connects to the communication device 10 to limit the connection of the protected terminal 30 to the relay device 20. This is because the protected terminal 30 cannot be connected to the relay device 20 and can be connected only to the communication device 10 (that is, a state in which the guardian can monitor).

Further, 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 input something to the device 10. This is because the protected person can be physically moved to the vicinity of the communication device 10 (that is, the environment in which the guardian can monitor).

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

FIG. 10 is a block diagram showing the present embodiment.

The configuration and operation of this embodiment will be described below. In the following, the description of the components and operations that overlap with the first embodiment will be omitted.

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

The communication device 10 and the relay device 60 are connected by wire or wirelessly, and data can be exchanged 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 the 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) for storing a program and a processor (not shown) for reading the program into a memory and executing an instruction.

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 motion sensor that detects a person's movement. The sensor 70 responds to the sensor status reply instruction signal of the relay device input unit 63, and when detecting a human movement, returns a signal indicating "reaction" to the relay device input unit 63, and the human operation. If is not detected, a signal indicating "no response" is returned. The sensor 70 may be included in the relay device 60.

Since the terminal restriction status table 621 has the same configuration as the terminal restriction status table 221 shown in FIG. 4, detailed description thereof will be omitted.

Next, the operation of the relay device control unit 61 when registering the 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 device 10 at this time is the same as the operation shown in the flowchart of FIG. 5, and thus the description thereof will be omitted.

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

Next, the relay device control unit 61 receives the signal from the sensor 70 via the relay device input unit 63. Then, when the signal received from the sensor 70 is a signal indicating "reactive" (when "YES" in step S602), the relay device control unit 61 receives the connection restriction notification received from the communication device 10. It is determined whether or not the terminal identification information of the guardian terminal is included (step S603). Since the subsequent operations of steps S604 and S606 are the same as the operations of steps S203 and S205 of the flowchart shown in FIG. 5, the description thereof will be omitted. Then, the relay device control unit 61 transmits a connection restriction response including information that the connection restriction setting of the protected terminal 30 is completed to the communication device 10 (step S605).

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

After that, the relay device control unit 61 refers to the terminal restriction status table 621, and the protected terminal indicated by the terminal identification information registered in the terminal identification column of the record in which "restricted" is registered in the restriction status column. The connection restriction process of 30 to the relay device 60 is executed.

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

Next, the operation of the relay device control unit 61 when the restriction on the connection of the protected terminal 30 to the relay device 60 is released will be described with reference to the flowchart of FIG. The operation of the communication device 10 at this time is the same as the operation shown in the flowcharts of FIGS. 7 and 8, and thus the description thereof will be omitted.

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

Next, the relay device control unit 61 receives the signal from the sensor 70 via the relay device input unit 63. Then, when the signal received from the sensor 70 is a signal indicating "no reaction" (when "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). Since the subsequent operations of steps S704 and S706 are the same as the operations of steps S503 and S505 of the flowchart shown in FIG. 9, the description thereof will be omitted. Then, the relay device control unit 61 transmits a restriction release response including information that the connection restriction release of the protected terminal 30 is completed to the communication device 10 (step S705).

On the other hand, if the signal received from the sensor 70 in step S702 is a signal indicating "reactive" (when "NO" in step S702), the relay device control unit 61 is set to release the connection restriction. No. Then, the relay device control unit 61 transmits a connection restriction response including information 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 if another person impersonating the protected person tries to release the connection restriction of the protected person terminal 30 in an environment where the communication device 10 is present (that is, an environment in which the guardian can monitor), the sensor 70 can be used. If the received signal is "responsive", the connection restriction is not released.

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

The reason is that even if another person impersonates the protected person and goes into the environment where the communication device 10 is located (that is, the environment where the guardian can monitor), if the signal received from the sensor 70 is "responsive". 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 set to release the connection restriction. Therefore, the protected person to be restricted can be physically moved to the environment where the communication device 10 is located.

You may.

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) in which 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. A connection restriction notification indicating the above is transmitted 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 "restricted" in the restriction status column of the record registered in the terminal restriction status storage unit 92.

As described above, in the present embodiment, as in the first embodiment, when the protected person who uses the second terminal uses an external network such as the Internet, the guardian who uses the first terminal The effect is that the protected person can be physically moved to a monitorable environment (eg, around the guardian or under the supervision of the guardian, etc.).

The reason is that the connection of the second terminal to the relay device 90 is restricted by connecting the first terminal 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 state in which the guardian can monitor).
