  As shown in FIG. 7, the caller terminal 8 first attempts to make a call to the child communication terminal 3 through the mobile communication network 6 (step S201). At this time, the network connection device 4 detects a call transmission to the child communication terminal 3.

  Next, after detecting the outgoing call to the child communication terminal 3, the network connection device 4 notifies the communication control server 1 and also holds the incoming call of the child communication terminal 3 (step S202). Here, during suspension, the network connection device 4 enters a standby state for connection with the child communication terminal 3.

  Next, the communication control server 1 reads the communication control policy of the child communication terminal 3 stored in the database 13 in response to the notification from the network connection device 4, and determines whether or not to allow the child communication terminal 3 to receive a call. Is determined (step S203).

  When the incoming call from the child communication terminal 3 is not permitted (step S204), the communication control unit 111 notifies the network connection device 4 to reject the incoming call from the child communication terminal 3 via the communication interface 10 (step S205). .

  Next, the network connection device 4 rejects the incoming call from the caller terminal 8 of the child communication terminal 3, and issues a call incoming call rejection notice to the caller terminal 8 (step S206). The incoming call rejection notification may be in the form of a voice message or a message service. The issuer of the incoming call rejection notification is not limited to the network connection device 4 but may be the communication control server 1, for example. Further, the incoming call rejection notification may not be issued depending on the communication control policy of the child communication terminal 3 stored in the database 13.

  When permitting the incoming call of the child communication terminal 3 in step S204, the communication control unit 111 notifies the network connection device 4 via the communication interface 10 to allow the incoming call of the child communication terminal 3 (step S207).

  Next, in response to the notification of permission, the network connection device 4 cancels the call reception hold of the child communication terminal 3, and executes the call reception operation (step S208).

  As described above, the communication control system 1000 ends the incoming call operation from the caller terminal 8 of the child communication terminal 3.

  FIG. 8 is a flowchart showing an outline of an operation for making a call to the callee terminal 9 of the child communication terminal 3 in the communication control system 1000 according to the first embodiment. Note that the processing according to this flowchart may be executed based on the above-described program control by the CPU.

  As shown in FIG. 8, first, the child communication terminal 3 tries to make a call to the callee terminal 9 through the mobile communication network 6 (step S301). At this time, the network connection device 4 detects the outgoing call from the child communication terminal 3.

  Next, after detecting the call transmission from the child communication terminal 3, the network connection device 4 notifies the communication control server 1 and puts the call transmission from the child communication terminal 3 together (step S302).

  Next, the communication control server 1 reads the communication control policy of the child communication terminal 3 stored in the database 13 in response to the notification from the network connection device 4 and permits the call transmission from the child communication terminal 3. Judgment is made (step S303).

  When the call transmission from the child communication terminal 3 is not permitted (step S304), the communication control unit 111 notifies the network connection device 4 to reject the call call from the child communication terminal 3 via the communication interface 10 (step S304). S305).

  Next, the network connection device 4 rejects the call transmission from the child communication terminal 3 to the callee terminal 9, and issues a call call rejection notification to the child communication terminal 3 (step S306). The call origination rejection notification may be in the form of a voice message or a message service. The issuer of the call origination rejection notification is not limited to the network connection device 4, but may be the communication control server 1, for example. Further, the call origination rejection notification may not be issued depending on the communication control policy of the child communication terminal 3 stored in the database 13.

  When permitting a call transmission from the child communication terminal 3 in step S304, the communication control unit 111 notifies the network connection device 4 via the communication interface 10 to allow a call transmission from the child communication terminal 3 (step S307). ).

  Next, the network connection device 4 responds to the permission notice, cancels the hold of the outgoing call from the child communication terminal 3, and executes the outgoing call operation (step S308).

  As described above, the communication control system 1000 ends the call transmission operation of the child communication terminal 3 to the callee terminal 9.

  FIG. 9 is a flowchart showing an overview of the operation of temporarily releasing the communication control policy of the child communication terminal 3 in the communication control system 1000 according to the first embodiment. This operation is the same as when the notification of blocking access to the site 7 of the child communication terminal 3 is received (step S106) or when the notification of call origination rejection to the callee terminal 9 from the child communication terminal 3 is received (step S306). When the communication is rejected due to the communication control policy, the communication rejection of the child communication terminal 3 is temporarily canceled with the consent of the parent communication terminal 2, but the timing of performing this operation is not limited to these. . Note that the processing according to this flowchart may be executed based on the above-described program control by the CPU.

  As shown in FIG. 9, first, the child communication terminal 3 accesses and logs in to the communication control server 1 through the mobile communication network 6 and the network 5 (step S401). When the communication control server 1 accepts the login, the user authentication unit 110 reads the user information from the user authentication information storage unit 130 and authenticates the child communication terminal 3. In addition, the control circuit 11 of the communication control server 1 notifies access blocking to the site 7 of the child communication terminal 3 (step S106) and notification of call rejection from the child communication terminal 3 to the callee terminal 9 (step S306). ), The communication communication policy temporary release processing may be instructed and guided to the child communication terminal 3. In this case, the user authentication unit 110 does not have to authenticate the child communication terminal 3.

  When the login (authentication) fails (step S402), the communication control server 1 returns a notification that the login is impossible to the child communication terminal 3, and ends the process (step S403).

  When the login (authentication) is successful (step S402), the control circuit 11 of the communication control server 1 instructs the child communication terminal 3 to temporarily cancel the communication control policy via the network connection device 4, and temporarily The guide data for the release process is transmitted to the child communication terminal 3. Thereby, the child communication terminal 3 displays the guidance of the temporary release processing of the communication control policy of the child communication terminal 3 on a display unit (not shown). Then, the child communication terminal 3 operates a non-illustrated operation input unit based on the displayed guidance, inputs a temporary release application, and transmits temporary release application data to the communication control server 1. The communication control server 1 accepts the temporary release application data and stores it in the memory 12 (step S404).

  Next, when the slave communication terminal 3 recognizes the application for temporary release of its communication control policy, the control circuit 11 of the communication control server 1 sends a notification that the application for temporary release has been made via the network connection device 4. To the parent communication terminal 2 (step S405).

  Next, the parent communication terminal 2 accesses the communication control server 1 through the mobile communication network 6 and the network 5 and logs in (step S406). When logging in, the user authentication unit 110 reads the user information from the user authentication information storage unit 130 and authenticates the parent communication terminal 2.

  If the login (authentication) fails (step S407), the communication control server 1 returns a notification that the login is impossible to the parent communication terminal 2 via the network connection device 4, and ends the process (step S408).

  When the login (authentication) is successful (step S407), the control circuit 11 of the communication control server 1 reads the temporary release application data from the memory 12. Then, the control circuit 11 transfers the temporary release application data to the communication interface 10, and the communication interface 10 transmits the temporary release application data to the parent communication terminal 2 via the network connection device 4. Thereby, the display part (not shown) of the parent communication terminal 2 displays the content that the child communication terminal 3 has applied for temporary cancellation. Then, the parent communication terminal 2 operates an operation input unit (not shown) based on the displayed guidance, and inputs whether to cancel the communication control policy temporarily. Based on this input, the parent communication terminal 2 transmits data indicating whether or not to temporarily cancel to the communication control server 1. The communication control server 1 accepts data indicating whether to cancel temporarily (step S409). At this time, the parent communication terminal 2 may determine the period of temporary release effect.

  The control circuit 11 of the communication control server 1 analyzes data indicating whether or not to temporarily cancel. When the parent communication terminal 2 recognizes that the temporary release of the communication control policy of the child communication terminal 3 has been rejected (NO in step S410), the communication control server 1 rejects the temporary release of the communication control policy of the child communication terminal 3. Is issued to the child communication terminal 3 (step S411).

  On the other hand, when the parent communication terminal 2 recognizes that the temporary release of the communication control policy of the child communication terminal 3 is permitted (step S410), the communication control server 1 controls the communication control of the child communication terminal 3 stored in the database 13. The fact that temporary release is permitted is added to the policy (step S412).

  As described above, the communication control system 1000 ends the operation of temporarily releasing the communication control policy of the child communication terminal 3.

  Next, effects of the first exemplary embodiment of the present invention will be described.

  The communication control system 1000 according to the present embodiment described above can block unintended access to the child communication terminal 3 for a user who wants to control the communication of the child communication terminal 3.

  This is because the following configuration is included. That is, firstly, the communication control server 1 determines whether to cancel the access blocking / call hold based on the communication control policy of the child communication terminal 3 stored in the database 13 and notifies the network connection device 4 of the result. . Secondly, the network connection device 4 executes access blocking and release / continuation of outgoing / incoming call hold based on the determination result of the communication control server 1. Thirdly, unless the parent communication terminal 2 has permission, the child communication terminal 3 cannot temporarily cancel its own communication control policy. Thereby, the communication of the child communication terminal 3 is controlled according to the communication control policy of the child communication terminal 3 intended by the parent communication terminal 2, so that it is not intended for the user who wants to control the communication of the child communication terminal 3. 3 can be blocked.
