[First Embodiment]
The first embodiment of the present invention will be described below.
FIG. 1 is a diagram showing an overview of a control system 1 according to the present embodiment.

  The control system 1 includes a parent terminal 10 and a child terminal 20 as portable communication terminals such as a smartphone, a mobile phone, a tablet terminal, or a game machine.

  The parent terminal 10 and the child terminal 20 mutually transmit and receive data by direct wireless communication. Specifically, for example, in accordance with the BLE (Bluetooth (registered trademark) Low Energy) protocol, the parent terminal 10 as the master device intermittently searches for scanning (Advertising) from the child terminal 20 as the slave device (Scanning). ) Then, in the communicable radio wave state (reception sensitivity), communication settings are established in both the parent terminal 10 and the child terminal 20, and communication connection is established.

  The parent terminal 10 receives application information regarding an application installed in the child terminal 20 by direct wireless communication and presents it to the user. The application information includes the application name, icon data, and the like, and these are displayed in a list on the parent terminal 10.

The parent terminal 10 receives designation input for use restriction or restriction release from the user individually or collectively for each of the applications displayed in a list. Further, the content of usage restriction or restriction release may be automatically set according to the conditions input in advance to the parent terminal 10.
The display of the parent terminal 10 includes, for example, a switch for switching prohibition or permission of use for each application, a threshold value of distance from the child terminal 20 or time information (permission period) as a condition for permitting or prohibiting use of the application. Etc. are provided.

  The parent terminal 10 transmits setting information for restricting or releasing the use of the application to the child terminal 20 by direct wireless communication. As a result, the child terminal 20 controls restriction or release of at least a part of functions related to use of the installed application. At this time, the child terminal 20 may hide the icon of the application that has been disabled.

FIG. 2 is a diagram illustrating a functional configuration of the parent terminal 10 and the child terminal 20 according to the present embodiment.
The parent terminal 10 includes a storage unit 11, a communication control unit 12, a reception processing unit 13 (first reception processing unit), a display control unit 14, a limit setting unit 15, and a transmission processing unit 16 (first processing unit). A transmission processing unit).
The child terminal 20 includes a display control unit 21, a storage unit 22, a communication control unit 23, a transmission processing unit 24 (second transmission processing unit), a reception processing unit 25 (second reception processing unit), A distance measuring unit 26 and a restriction processing unit 27 are provided.

  The storage unit 11 is a storage area for various programs and various data for causing the hardware group to function as the parent terminal 10. Specifically, the storage unit 11 stores a program to be executed by each unit in order to realize the functions of the present embodiment. In addition, the storage unit 11 stores setting information regarding usage restrictions on the application of the child terminal 20 input from the user of the parent terminal 10.

  The communication control unit 12 controls direct wireless communication with other terminals. Specifically, the communication control unit 12 conforms to the BLE protocol and operates as a master device. That is, the communication control unit 12 intermittently searches for identifiers and provided services transmitted from peripheral devices, determines the child terminal 20 to be connected, and transmits a connection request. The communication control unit 12 may determine the child terminal 20 to be connected by collating with the ID of the child terminal 20 registered in advance.

  When the child terminal 20 responds to the connection request, the communication control unit 12 performs communication settings and establishes a communication connection with the child terminal 20. The communication control unit 12 maintains the communication connection state with the child terminal 20 while the radio wave state is at a communicable level.

  The reception processing unit 13 receives application information related to applications installed in the child terminal 20 from the child terminal 20 by the communication control unit 12.

  The display control unit 14 performs control to display on the display a screen for accepting data input from the user, a screen for processing results by the parent terminal 10, or the like. In the present embodiment, the display control unit 14 presents application information such as application names and icons received from the child terminal 20 to the user of the parent terminal 10 by displaying the application information in a list format, for example.

  The restriction setting unit 15 sets setting information for restricting or releasing the use of the application according to the distance between the parent terminal 10 and the child terminal 20 regarding the application selected by the user among the displayed applications. Generated and stored in the storage unit 11.

The transmission processing unit 16 transmits the generated setting information to the child terminal 20 by the communication control unit 12.
The setting information may include, in addition to the information on whether or not the application can be used, time information as a trigger for switching the availability, and the time zone serving as a reference for the time information, the presence or absence of daylight saving time, and the like.

The display control unit 21 performs control to display a screen for accepting data input from the user or a processing result screen by the child terminal 20 on the display. The display control unit 21 displays the icon of the application installed on the child terminal 20 on the home screen, for example, but the application icon whose use is restricted by the setting information received from the parent terminal 10 may be deleted. .
For example, when the use of the application is restricted or released depending on the distance between the parent terminal 10 and the child terminal 20, the display control unit 21 displays an icon according to the control of the restriction processing unit 27 in accordance with the switching of the restriction. Or switch the non-display.

  The storage unit 22 is a storage area for various programs and various data for causing the hardware group to function as the child terminal 20. Specifically, the storage unit 22 stores a program to be executed by each unit for realizing the functions of the present embodiment. In addition, the setting information received from the parent terminal 10 is stored in the storage unit 22 and is referred to by the restriction processing unit 27.

The communication control unit 23 controls direct wireless communication with other terminals. Specifically, the communication control unit 23 conforms to the BLE protocol and operates as a slave device. That is, the communication control unit 23 intermittently broadcasts its own terminal identifier and provided service, and waits for a connection request from another terminal. When the communication control unit 23 receives a connection request from the parent terminal 10, it returns a response to perform communication settings and establishes a communication connection with the parent terminal 10.
At this time, the communication control unit 23 responds only to a connection request from the parent terminal 10 that matches the ID registered in advance. For example, in the case of a child terminal, it is assumed that the telephone number of the guardian (parent) is registered in the first or higher speed dial of the child terminal 20. Therefore, the communication control unit 23 may respond only to a connection request from the parent terminal 10 registered in the first or higher order of the speed dial.

  The transmission processing unit 24 transmits application information related to the application installed in the child terminal 20 to the parent terminal 10 with which communication connection is established by the communication control unit 23.

  The reception processing unit 25 receives setting information for performing application use restriction or restriction release from the parent terminal 10 by the communication control unit 23.

  The distance measuring unit 26 measures the distance between the child terminal 20 and the parent terminal 10 based on the strength of reception sensitivity (for example, RSSI (Received Signal Strength Indicator)) in the communication control unit 23.

The restriction processing unit 27 performs application use restriction or restriction release based on the measured distance according to the setting information received from the parent terminal 10.
Specifically, the restriction processing unit 27 permits or restricts the use of the selected application if the distance measured by the distance measuring unit 26 is within the designated distance based on the designated distance included in the setting information. . On the contrary, when the measured distance is longer than the specified distance or the distance cannot be measured by the distance measuring unit 26, the restriction processing unit 27 restricts the use of the permitted application or permits the use of the restricted application. To do.

At this time, the restriction processing unit 27 restricts or cancels the use of the application by blocking the user's access to the restricted application according to the setting information.
For example, the restriction processing unit 27 controls the display control unit 21 to switch between display and non-display of an icon that is originally displayed on the home screen, the application list, the usage history list, and the like for instructing the user to start the application. . That is, the restriction processing unit 27 displays an icon of this application on the condition that the use of the application is released, and when the use of the application is restricted, the restriction processing unit 27 does not display the icon so that the application of the application by the user is not displayed. Restrict startup.

Further, when restricting the use of an application, the restriction processing unit 27 may restrict the activation by invalidating the activation instruction of the application.
Furthermore, the restriction processing unit 27 may more reliably suppress activation by the user by invalidating various drivers that can accept an application activation instruction (for example, command input).

Further, when restricting the use of an application, the restriction processing unit 27 may terminate the application being executed and stop all functions of the application operable in the background.
Alternatively, when restricting the use of an application, the restriction processing unit 27 may continue the operation of the application being executed and restrict the use by blocking a user interface (input / output) in the application. For example, in the case of an application or the like for exchanging messages with other terminals, the restriction processing unit 27 may control the display so that the message can be received in the background and the message can be displayed when the application use restriction is removed. Good.

  The restriction processing unit 27 performs initial setting for restricting the use of the application when a new application is installed in the child terminal 20 before receiving the setting information regarding the necessity of use restriction. In addition, activation of this application may be suppressed.

FIG. 3 is a sequence diagram showing a setting process of application use restriction or restriction release in the control system 1 according to the present embodiment.
In this process, the child terminal 20 is actively controlled by the parent terminal 10 as an opportunity.

  In step S1, the child terminal 20 intermittently broadcasts its own terminal identifier and provided service as a slave device of the BLE protocol. Further, the parent terminal 10 searches for an identifier and a provided service that are intermittently transmitted from the child terminal 20 as a master device of the BLE protocol.

  In step S2, the parent terminal 10 collates the received identifier and the provided service with information of a specific child terminal 20 registered in advance, and determines whether or not it is a connection target. If this determination is YES, the process moves to step S3, and the communication connection procedure proceeds.

  In step S <b> 3, when the parent terminal 10 finds the identifier of the specific child terminal 20 to be controlled and the provided service, the parent terminal 10 transmits a connection request to the child terminal 20.

  In step S4, the child terminal 20 collates the identifier of the parent terminal 10 included in the connection request with the information of the specific parent terminal 10 registered in advance, and determines whether or not it is a connection target. If this determination is YES, the process moves to step S5, and the communication connection procedure proceeds.

  In step S <b> 5, the child terminal 20 responds to the connection request from the parent terminal 10. The parent terminal 10 and the child terminal 20 perform communication settings on both sides, thereby establishing a BLE communication connection.

  In step S6, the parent terminal 10 requests the child terminal 20 to transmit application information.

  In step S <b> 7, the child terminal 20 transmits application information related to the application installed in the own terminal to the parent terminal 10.

  In step S <b> 8, the parent terminal 10 displays the application information received from the child terminal 20. At this time, the parent terminal 10 accepts only the information to be changed from the current state by displaying the already set usage restriction or restriction release information together.

  In step S9, the parent terminal 10 generates and stores setting information for use restriction or execution restriction release according to the contents received in step S8.

  In step S10, the parent terminal 10 transmits the setting information generated in step S9 to the child terminal 20.

  In step S <b> 11, the child terminal 20 stores the setting information received from the parent terminal 10. The child terminal 20 performs application use restriction or restriction release processing according to the setting information.

FIG. 4 is a flowchart illustrating an example of a processing procedure of application use restriction or restriction release in the child terminal 20 according to the present embodiment.
This example shows a case where the application usage restriction is canceled only within a specified distance, and a series of steps are repeatedly executed.

  In step S <b> 21, the restriction processing unit 27 determines whether communication between the parent terminal 10 and the BLE is established and mutual communication is possible. If this determination is YES, the process proceeds to step S22, and if the determination is NO, the process proceeds to step S25.

  In step S22, the distance measuring unit 26 measures the distance from the parent terminal 10 based on the reception sensitivity of the BLE radio wave.

  In step S23, the restriction processing unit 27 determines whether or not the distance measured in step S22 is within the distance specified by the setting information. If this determination is YES, the process proceeds to step S24, and if the determination is NO, the process proceeds to step S25.

  In step S24, the restriction processing unit 27 releases the use restriction and permits the use of the restricted application because the parent terminal 10 is nearby.

  In step S25, the restriction processing unit 27 restricts the use of the application because the distance from the parent terminal 10 is long or the distance cannot be measured.

  According to the present embodiment, the control system 1 transmits and receives application information and setting information between the parent terminal 10 and the child terminal 20 using direct wireless communication, and restricts or cancels the use of the application in the child terminal 20. I do. Furthermore, in the child terminal 20, it is possible to realize usage restriction or restriction release control according to the distance from the parent terminal 10 measured based on the reception sensitivity in wireless communication. Therefore, the control system 1 can perform application use restriction or restriction release with high accuracy according to the distance between terminals by direct wireless communication without using an external network.

At this time, the child terminal 20 can easily limit or cancel the application using the distance designated from the parent terminal 10 as a threshold.
Further, in a situation where the reception sensitivity of direct wireless communication is reduced and communication is not possible, the actual distance cannot be measured, so the application usage control is set to an initial state, for example, a usage restricted state. Thereby, when the distance between terminals is unknown, the control system 1 can suppress unintended use restriction cancellation or use restriction.

  Since the child terminal 20 performs control so that the icon of the application whose use is restricted is not displayed according to the instruction from the parent terminal 10, it is possible to suppress the activation of the application whose use is restricted by the user, and the user can easily You can see that it is in a restricted state.

  Since the child terminal 20 invalidates the activation instruction of the application whose use is restricted by the instruction from the parent terminal 10, even when the activation instruction is given by the user by some means, the application of the application is more reliably used. Can be limited.

When the use of the application is restricted, the child terminal 20 can more reliably restrict the use of the target application by terminating the already-executed target application.
Alternatively, the child terminal 20 can permit the execution of the background process by continuing the operation of the target application and blocking the user interface when restricting the use of the application. Thereby, when the use restriction of the application is released, the user can immediately access the processing result in the background, so that convenience is improved.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described.
In the first embodiment, the child terminal 20 is actively controlled in response to the parent terminal 10, but in the present embodiment, the child terminal 20 is triggered in response to the child terminal 20 passively. 20 control is performed. Specifically, the parent terminal 10 performs restriction release setting as a response to the application from the child terminal 20.
In addition, although the functional block with which the control system 1 which concerns on this embodiment is provided is the same as that of 1st Embodiment (FIG. 2), the following functions are added, respectively.

  The transmission processing unit 24, together with application information related to a specific application whose use is restricted among the applications installed in the child terminal 20, the application data for releasing the restriction on the use of the specific application, 23 to the parent terminal 10.

  The reception processing unit 25 receives permission data from the parent terminal 10 by the communication control unit 23, that is, setting information for releasing the restriction on the use of a specific application.

The restriction processing unit 27 releases the restriction on the use of a specific application according to the setting information.
At this time, the restriction processing unit 27 may temporarily remove the restriction on the use of a specific application based on the specified period information included in the setting information. Alternatively, the restriction processing unit 27 may continuously release the restriction on the use of a specific application until the next use restriction.

  In addition, when the child terminal 20 satisfies the condition for releasing the restriction based on the distance in the first embodiment (for example, when the parent terminal 10 and the child terminal 20 are close to each other within the specified distance), the user applies for restriction release. A configuration in which an input is received and permission for actually releasing the restriction is obtained from the parent terminal 10 may be employed.

  FIG. 5 is a sequence diagram showing a setting process for canceling the application use restriction in the control system 1 according to the present embodiment.

  In steps S <b> 1 to S <b> 5, the parent terminal 10 and the child terminal 20 establish a direct wireless communication connection, similarly to the process (FIG. 3) in the first embodiment.

  In step S <b> 7 a, the child terminal 20 transmits, to the parent terminal 10, application information related to applications whose use is restricted among the applications installed in the terminal as a restriction release application.

  In step S8a, the parent terminal 10 displays the application information received from the child terminal 20.

  In step S9a, based on the display information in step S8a, the parent terminal 10 accepts an input as to whether or not to permit (restrict restriction) the application, and generates and stores restriction release setting information when permitted. .

  In step S10a, the parent terminal 10 transmits the restriction release permission setting information generated in step S9a to the child terminal 20.

  In step S11a, the child terminal 20 stores the setting information received from the parent terminal 10. The child terminal 20 performs application use restriction or restriction release processing according to the setting information.

According to the present embodiment, the child terminal 20 can cancel the restriction by receiving a permission notice from the parent terminal 10 by making an application for restriction release to the parent terminal 10 regarding the application whose use is restricted. Thereby, the control system 1 is based on an explicit application from the child terminal 20 on the condition that the parent terminal 10 is in a nearby communicable place or within a specified distance (the parent is near). The parent terminal 10 can release the restriction.
At this time, the parent terminal 10 can temporarily release the restriction on the use of a specific application in the child terminal 20 based on the specified period information.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. Further, the effects described in the present embodiment are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the present embodiment.

The ID of the connection target terminal held in the parent terminal 10 and the child terminal 20 may be data encrypted with key information. This improves safety.
Further, the IDs of these connection target terminals may be registered according to an explicit approval operation by both the parent terminal 10 and the child terminal 20 users.

In the above-described embodiment, the case where the parent terminal 10 and the child terminal 20 have a one-to-one relationship has been described as an example, but the present invention is not limited to this. For example, the parent terminal 10 may control a plurality of child terminals 20.
In addition, the child terminal 20 may be controlled by the plurality of parent terminals 10, and the application use restriction may be released by all of the plurality of parent terminals 10 according to a predetermined number or any permission setting. For example, the child terminal 20 may be selectively connected to the parent terminal 10 located at the closest distance.

  In the above-described embodiment, the parent terminal 10 is described as a master device and the child terminal 20 is a slave device. Conversely, the child terminal 20 may operate as a master device and the parent terminal 10 may operate as a slave device.

  The restriction processing unit 27 performs initial setting for restricting the use of the application when a new application is installed in the child terminal 20, and before receiving the setting information regarding the necessity of use restriction, You may suppress starting this application.

When the parent terminal 10 acquires application information from the child terminal 20, the restriction setting unit 15 may generate setting information based on a predetermined condition stored in advance. For example, the restriction setting unit 15 may set a use restriction for a new application, and may perform a temporary restriction release setting with a limited time for a restriction release application.
As described above, the setting information is automatically generated and provided to the child terminal 20, so that the trouble of the user of the parent terminal 10 is reduced and the convenience is improved.

  Further, the child terminal 20 may control application restriction or restriction release according to a composite condition based on distance from the parent terminal 10 and time information. That is, for example, the restriction processing unit 27 may release the use restriction when the distance from the parent terminal 10 is within a specified range and within a specified time.

At this time, the restriction processing unit 27 forcibly acquires the current time information of the designated time zone included in the setting information. Thereby, the child terminal 20 suppresses the use restriction or restriction release of the application from being performed at a time different from the intention when the parent terminal 10 is set with reference to a different time zone.
In addition, the restriction processing unit 27 may prohibit setting changes of time information such as a time zone or daylight saving time. Thereby, the child terminal 20 suppresses that time information different from the intention when set by the parent terminal 10 is used for control.
Further, the child terminal 20 may receive the reference time information as setting information from the parent terminal 10, and may count the current time from the reference time information as a starting point. Thereby, even if the user can falsify the time held by the child terminal 20, the child terminal 20 can perform control based on the correct time information.

  The control method by the control system 1 is realized by software. When implemented by software, a program constituting the software is installed in the information processing apparatus (parent terminal 10 and child terminal 20). These programs may be recorded on a removable medium such as a CD-ROM and distributed to users, or may be distributed by downloading to a computer via a network. Furthermore, these programs may be provided to a computer as a Web service via a network without being downloaded.
