The control unit 106 includes an RF communication unit 101, a display unit 102, and a key input unit 103 of the mobile communication terminal 100. By exchanging data and control signals with each of the functional units such as the voice input / output unit 104, the camera unit 105, the control ID detection unit 107, the position information acquisition unit 108, the acceleration sensor 109, and the storage unit 110, the mobile unit Various functions of the communication terminal 100 are realized. In addition, the control unit 106 according to the present embodiment stores a control ID placed on a trigger signal transmitted in an area where the operation of the application program should be restricted, and the control ID detection unit 107 detects the control ID. In this case, the execution of the application program is restricted by an operation described later.

  The control ID detection unit 107 provides a function of detecting information of a control ID placed on a trigger signal added to the mobile communication terminal 100 and notifying the control unit 106 of the information. Here, the trigger signal is unique to each place where the functions of the mobile communication terminal 100 are to be partially restricted, such as near a priority seat in a train, near a medical device, and inside a theater / movie theater. This is a signal generated to notify the terminal of a correct control ID. In the present embodiment, a case where a weak high-frequency magnetic field is generated by an antenna provided in such a place and this is used as a trigger signal carrying a control ID is shown.

  FIG. 2 is a diagram showing a configuration example of the control ID detection unit 107 in more detail. As shown in FIG. 2, the control ID detection unit 107 includes an antenna unit 111 and a control ID extraction unit 112. The antenna unit 111 is a small three-axis induction coil, and generates a predetermined current signal by receiving electromagnetic induction from a trigger signal that is a high-frequency magnetic field. The control ID extraction unit 112 is a circuit that extracts a control ID from the current signal generated by the antenna unit 111. There is no limitation on the method of placing the control ID on the trigger signal and the method of extracting the control ID from the current signal generated by the antenna unit 111 based on the trigger signal, and ON-OFF Amplitude Keying may be used simply or otherwise. You may use this method. It is also possible to perform encryption in order to increase the security strength.

  The position information acquisition unit 108 receives a signal from a GPS (Global Positioning System) satellite under the control of the control unit 106, acquires the current position of the mobile communication terminal 100, and returns the coordinates to the control unit 106. have. The method for acquiring the position information is not limited to the one using GPS, and other position information systems supplementing GPS may be used together, or a position information system different from GPS is used. It does not matter.

  The acceleration sensor 109 is a sensor that detects the acceleration received by the mobile communication terminal 100 and outputs a corresponding signal to the control unit.

It is done.

The storage unit 110 is a readable / writable memory for storing predetermined information under the control of the control unit 106 and providing information stored in the control unit 106. Further, as described above, various types of programs are stored in the storage unit 110, and the control unit 106 is performed by executing the programs with a CPU (not shown).

  FIG. 3 is a software configuration diagram showing an outline of a program stored in the storage unit 110 and realizing various functions in the mobile communication terminal 100 by being executed by the control unit 106. As shown in FIG. 3, in this mobile communication terminal 100, an operating system is mounted on various device drivers / protocol stacks, and on the API provided by the operating system, the date of the day, time, radio wave intensity, battery remaining A system UI program and a clock display program that implement the user interface by displaying the amount and system state on the display unit 102 are implemented.

  In the above, while the system UI program and the clock display program cannot display information other than system information in principle, application programs such as a browser, a mailer, an electronic dictionary, a file viewer, a PIM, and a memo pad are used by the user. It can be freely input and saved, or has a function of displaying information other than system information according to the user's specification. The line call program is the same in that the input telephone number is displayed on the display unit 102. In the present invention, in order to prevent an application program having a function of displaying information other than the system information from being a cause of fraud during classes and tests, the control ID detection unit 107 controls the execution of the application program from the trigger signal. When the ID is detected, the control unit 106 automatically restricts the execution of these application programs.

  In order to achieve the above configuration, the control unit 106 is a target for restricting execution of preinstalled application programs other than the system UI and the clock program, and also restricts execution of application programs installed later by the user. To do. Although the execution of the system UI program is not limited here, when the system UI program can freely display the wallpaper specified by the user, the system UI program is used to prevent fraud using this wallpaper. You should also restrict execution.

  Restricting the execution of an application program refers to, for example, terminating a running application program and prohibiting the start of a new application program, but is not limited to this. What is necessary is just to perform in the range which can prevent the fraud using 100. For example, the display device 102, the key input unit 103, and the voice input / output unit 104 of the mobile communication terminal 100 may be configured to be unusable by an application program.

  Hereinafter, an operation of detecting a trigger signal in the mobile communication terminal 100 of the present embodiment and implementing the function restriction method of the mobile communication terminal according to the present invention will be described with reference to the flowchart of FIG.

  In this operation, after waiting for a predetermined time (ST101), the control unit 106 determines whether the control ID detection unit 107 has detected a control ID that restricts execution of the application program (ST102). Here, as a situation in which the control ID detection unit 107 detects the control ID, for example, if an antenna is previously placed in a classroom where a class or examination is performed and a high-frequency magnetic field signal on which the control ID is mounted is generated. A case where a user carrying the mobile communication terminal 100 enters the classroom in order to perform a class or an examination can be given. A case where a predetermined high-frequency magnetic field signal is generated in the classroom only during a class or examination with the same configuration can also be illustrated.

  If it is determined in ST102 that the control ID has been detected, it is then determined whether the control unit 106 is restricting execution of the application program (ST103). Here, if it is determined that the execution of the application program is already restricted, there is no need to change this, so the process returns to ST101 and the same processing is repeated. On the other hand, if it is not determined that the execution of the application program is being restricted, it is first determined whether there is an application program being executed (ST104), and if it is determined that there is an application program being executed. Terminates the application program being executed by the control unit 106 (ST105).

  Thereafter, control unit 106 starts execution restriction of the application program (ST106). That is, even if the control unit 106 receives an instruction to start the application program, the control unit 106 does not start the application program. If it is not determined in ST104 that there is an application program being executed, unlike the above, ST106 is directly executed without going through ST105. After starting execution control of the application program in ST106, the process returns to ST101 and the same processing is repeated.

  On the other hand, if it is not determined in ST102 that the control ID has been detected, it is determined whether execution of the application program is being restricted (ST107). If it is determined that the application program is being restricted, the application program execution restriction is canceled (ST108). Here, the situation in which the control ID detection unit 107 does not detect the control ID and the execution of the application program is restricted refers to leaving the classroom where a predetermined high-frequency magnetic field signal carrying the control ID is applied. In this case, the case where the predetermined high-frequency magnetic field signal is cut off after the lesson or the examination is finished can be cited. If it is not determined that the execution of the application program is restricted in ST107, the process returns to ST101 and the same process is repeated.

  By the operation as described above, when the mobile communication terminal 100 of the present embodiment detects a high-frequency magnetic field carrying a control ID, execution of the application program is restricted, and the high-frequency magnetic field goes out of range or the magnetic field is cut off. Thus, when the control ID is not detected, the restriction is released. Therefore, the mobile communication terminal 100 brought into the classroom is restricted by executing an application program by generating an RF magnetic field carrying a control ID in a classroom during a class or examination, etc. Can no longer be used. In addition, after the class or examination is completed, the application program execution restriction in the mobile communication terminal 100 is released by taking the mobile communication terminal 100 out of the classroom or by stopping the generation of the high-frequency magnetic field in the classroom. And can be used normally.

  In addition, although the case where the control unit 106 determines whether or not the control ID is periodically detected is shown here, the control ID detection unit 107 detects that the control ID for restricting the execution of the application program is detected. It is also possible to adopt an event-driven configuration in which an event is notified to the control unit 106 and the control unit 106 restricts execution of the application program in response to the event notification.

The embodiment of the present invention has been described above, but the present invention is not limited to this, and it is needless to say that various improvements and modifications can be made without departing from the spirit of the present invention. For example, in the mobile communication terminal 100 that detects the control ID for restricting the execution of the application program, not only the execution of the application program such as the browser and the mailer is restricted, but also a specific program such as a clock display program (class or The display unit 102 may be occupied by fixedly executing a program that is not available for fraud during the test.
