It is possible to connect.

[Outline of the mobile phone terminal of this embodiment]
In the present embodiment, the mobile phone terminal 8 is not only a terminal dedicated to the manager but also a person under the management of the manager, that is, a child when the parent is a manager (guardian), for example. Conversely, a terminal used by an elderly parent or the like when the child is an administrator, or a terminal mounted as a security component in a car owned by the administrator. In the present embodiment, description will be given by taking as an example a case where the user of the mobile phone terminal 8 is different from the administrator.

  In the present embodiment, the mobile phone terminal 8 has a positioning function using, for example, GPS, and the administrator can search for the position of the terminal 8 using the personal computer 1.

  In addition, the cellular phone terminal 8 of the present embodiment is completely powered unless the predetermined authentication information registered in advance is inputted when the power OFF button is pressed and the power is turned off (the power is turned off). Has a function that cannot be turned off. That is, in the mobile phone terminal 8 of the present embodiment, when the power OFF button is pressed without inputting predetermined authentication information, for example, display display, key illumination, lighting of an incoming lamp, key operation sound, ringtone All functions that can recognize that the terminal 8 is operating from the outside (ie, that the power is on) such as the output of the vibrator and the vibration of the vibrator are turned off, while viewed from the outside. Functions that do not know whether they are operating, especially GPS positioning functions required for position search, communication functions required for information communication for sending and receiving telephones and e-mails, and web access, the above communication functions and GPS positioning functions A time measurement function for performing a timer operation to turn ON / OFF at regular intervals as needed, sent from the administrator side via the Internet 2 etc. When control information is received via the communication function, a control function for controlling each function of the mobile phone terminal 8 (in this case, a function that cannot recognize the operation state from the outside) according to the control information, The ON state is maintained. In addition, for example, a Brew (Binary runtime environment for wireless) function, a Java (registered trademark) function, and the like can be operated without knowing whether they are operating from the outside. In the following description, as described above, when the power OFF button is pressed to turn off the power, predetermined authentication information is not input, and all that can recognize that the terminal 8 is operating from the outside. On the other hand, the state where the GPS positioning function, the communication function, the time measurement function, the control function, etc. are kept in the ON state will be referred to as “apparent power OFF state”. .

[Control when pressing the power OFF button]
FIG. 3 shows a flowchart of processing and control of the control unit 10 when the power OFF button is operated to instruct power OFF.

  In FIG. 3, the control unit 10 checks whether or not the power OFF button has been pressed as the process of step S1, and maintains the normal standby mode in step S2 when the power OFF button has not been pressed. To do. On the other hand, when the power OFF button is pressed, the control unit 10 advances the process to step S3.

  When the process proceeds to step S3, the control unit 10 performs a predetermined number of times by the input of the above-described password or authentication using a biometric authentication device before or after the power-off button is pressed. It is determined whether authentication information has been input. When authentication information has been input, the power is completely turned off in step S10. On the other hand, when the authentication information is not input, the control unit 10 advances the processing to step S4.

  In step S4, the control unit 10 shifts the operation mode of the terminal (hereinafter referred to as “apparent power-off mode”) to “apparent power-off state” and from the outside. To the operation mode (hereinafter referred to as “secret operation mode”) that performs positioning of the current position and transmission of its position information, for example, if necessary, without knowing whether the terminal is operating. Transition the operation mode.

  At this time, the control unit 10 determines whether or not the timer operation is set as the process of step S5. When the timer operation is set, the operation mode of the terminal is set to the timer in step S6. Transition to operation mode. That is, in this case, in the “secret operation mode”, the position search and position information transmission functions are normally turned off, and the position search and position information transmission functions are performed at regular intervals set by a timer. Is turned on to execute position search and transmit position information. On the other hand, when the timer operation is not set in step S5, the control unit 10 advances the process to step S7.

  In step S7, the control unit 10 acquires the remaining capacity information of the battery 18 from the power management IC 17, determines whether or not the remaining capacity of the battery 18 is equal to or less than a predetermined threshold, and the remaining battery capacity is predetermined. If there is a possibility that the threshold value is not reached, the process proceeds to step S6, and the operation mode of the terminal is changed to the timer operation mode. On the other hand, if the remaining battery level is sufficient, the control unit 10 advances the process to step S8.

  Proceeding to the process of step S8, when the communication circuit 11 is in the operation state in the “secret operation mode”, the control unit 10 receives the notification from the administrator or the administrator by e-mail or the like via the Internet 2, for example. It is determined whether or not control information from a legitimate person such as the person who received the request has been received, and when the control information has not been received, the process returns to step S3. In this case, it is determined No in step S3, and the previous operation mode is maintained in step S4, and the same processing as described above is performed in steps S5 to S7.

  On the other hand, if it determines with control information having been received in step S8 and advances a process to step S9, the control part 9 will perform the setting and control corresponding to the said control information.

  Here, in the case where the process proceeds from step S8 to step S9, if the control information is control information for instructing setting of a timer operation, change of a set time, or the like, the control unit 10 responds to the instruction. After setting the timer operation, the process returns to step S3. In this case, the control unit 10 determines No in step S3, maintains the previous operation mode in step S4, and proceeds to step S6 assuming that the timer operation is set in step S5. Become.

  Further, for example, when the process proceeds from step S8 to step S9, if the control information is control information for instructing the release of the setting of the timer operation, the control unit 10 determines the timer according to the instruction of the control information. After canceling the operation setting, the process returns to step S3. In this case, the control unit 10 determines No in step S3, further maintains the previous operation mode in step S4, and further proceeds to step S7 assuming that the timer operation is not set in step S5. become.

  Further, for example, when the process proceeds from step S8 to step S9, if the control information includes authentication information from an administrator or the like and is control information instructing cancellation of the “apparent power OFF state”, The control unit 10 returns the process to step S3, performs a Yes determination in step S3, and further transitions the terminal to a complete power-off state in step S10.

  Further, for example, when the process proceeds from step S8 to step S9, if the control information is control information for requesting position search and transmission of position information, the control unit 10 follows the instruction of the control information. 27 causes the position measurement to be performed and the communication circuit 11 to transmit the position information, and then returns the process to step S3.

  Further, for example, when the process proceeds from step S8 to step S9, if the control information is control information for requesting acquisition of audio or camera image and transmission of information transmission, the control unit 10 After the voice is acquired by the microphone 21 or the image is taken by the camera unit 26 and the information of the voice and the image is transmitted from the communication circuit 11, the process returns to step S3.

  Thus, when the control information is received, the control unit 10 performs various control operations according to the instruction of the control information in step S9. Description of other operation examples is omitted.

[Control when pressing the power ON button]
FIG. 4 shows a flowchart of processing and control by the control unit 10 when the power ON button is pressed when the operation mode of the mobile phone terminal is “apparent power OFF mode”, for example.

  In FIG. 4, the control unit 10 checks whether or not the power ON button is pressed in the “apparent power OFF mode” as the process of step S <b> 21, and when the power ON button is not pressed, FIG. Returning to the flowchart of FIG. 3, when the power ON button is pressed, the process proceeds to step S22.

  When the processing proceeds to step S22, the control unit 10 cancels the “apparent power OFF mode” and turns on the power, and then proceeds to step S23.

  When the processing proceeds to step S23, the control unit 10 performs predetermined authentication, for example, by inputting the personal identification number or authentication using the biometric authentication device within a predetermined time after the power ON button is pressed. It is determined whether or not information has been input. If authentication information has been input, the process proceeds to step S26. If authentication information has not been input, the process proceeds to step S24.

  When the process proceeds to step S26, the control unit 10 cancels the “secret operation mode” and cancels the “timer operation mode”, and then sets the operation mode of the terminal in step S27. Transition to normal standby mode.

  On the other hand, when the process proceeds to step S24, the control unit 10 maintains the “secret operation mode” even when the power is on, and also maintains the operation mode when the “timer operation mode” is set, Thereafter, the process proceeds to step S25.

  When the processing proceeds to step S25, the control unit 10 sets the battery remaining amount display on the display to an empty display (battery exhaust warning display) even if the remaining amount of the battery is sufficient.

[Relationship between secret operation mode and timer operation mode]
The operation of the mobile phone terminal of the present embodiment is “secret operation mode”, and the operation differs depending on whether it is “timer operation mode”.

  FIG. 5 shows a flowchart of processing and control by the control unit 10 in accordance with the relationship between the “secret operation mode” and the “timer operation mode”. In the flowchart of FIG. 5, the “secret operation mode” is applied regardless of whether the terminal is in the “apparent power OFF mode” or the power ON state.

  In FIG. 5, when the operation mode of the terminal is “secret operation mode”, the control unit 10 determines whether or not the current operation mode is “timer operation mode” as processing in step S <b> 31. When it is not “operation mode”, the process proceeds to step S35, and when it is “timer operation mode”, the process proceeds to step S32.

  When the process proceeds to step S32, the control unit 10 determines whether or not the timer set time has been reached based on the time information from the clock unit 16, and returns to the timer set time when the timer set time is not reached. If YES, the process proceeds to step S33.

  When the process proceeds to step S33, the control unit 10 causes the GPS unit 27 to perform positioning, and then causes the position information to be transmitted from the communication circuit 11 in step S34, and an e-mail addressed to the terminal or the like. If there is any information, the information is received.

  On the other hand, when the process proceeds to step S35, the control unit 10 performs, for example, a communication operation for performing location registration with the base station, a communication operation for sending and receiving e-mails, and a communication operation for outgoing and incoming calls. It is determined whether any communication operation occurs. When the communication operation occurs, the process proceeds to step S33, and when the communication operation does not occur, the process returns to step S31.

  If it is determined in step S35 that a communication operation occurs and the process proceeds to step S33, the control unit 10 performs positioning in the same manner as described above, and then, in step S34, simultaneously with the communication operation generated in step S35. The location information is transmitted, and when there is information such as an electronic mail addressed to the terminal, the information is received.

[Summary]
As described above, according to the embodiment of the present invention, when a mobile phone terminal is in the hands of a third party against the intention of the administrator or user, the third party is not informed. A clue for specifying the current position of the mobile phone terminal can be obtained. In particular, according to the present embodiment, since the third party does not know that authentication information is required when the power OFF button is operated, the third party operates the power OFF button to Even if the terminal is intended to be turned off, the current position can be specified and the terminal can be controlled.

  In addition, according to the present embodiment, the position search of the mobile phone terminal by the administrator or the like is performed without being known by a third party, regardless of the state of the terminal. On the contrary, according to the mobile phone terminal of the present embodiment, when a position search request is made from a person other than an authorized person such as an administrator, the vibrator is vibrated or a warning sound is generated. Unauthorized access can be prevented.

  In addition, according to the mobile phone terminal of the present embodiment, since the timer operation can be set, for example, it can be operated only once a day, and recharging cannot be performed. Even if it is placed, the decrease in the remaining amount of the battery can be reduced, and the period during which information communication is possible can be extended. Furthermore, according to the mobile phone terminal of this embodiment, for example, when the power is turned on without authentication from the “apparent power-off state”, the remaining battery level is displayed on the display even if the remaining battery level is sufficient. By displaying the empty display, it is possible to prompt the third party to turn off the power by giving a psychological pressure to the third party that the battery cannot be used, and this also reduces the remaining battery level. It becomes possible to suppress.

  In addition, when the battery is attached after the battery is removed, the mobile phone terminal of the present embodiment returns to the normal operation. Even in such a case, for example, the control information from the administrator side By transmitting, the operation of the terminal can be controlled without being known by a third party.

  Furthermore, according to the mobile phone system of this embodiment, when the mobile phone terminal of this embodiment is in the “apparent power OFF state”, only transmission of control information by e-mail or the like from an administrator or the like is permitted. Thus, it is possible to prevent other incoming e-mails from being received.

  Further, according to the mobile phone system of the present embodiment, when the mobile phone terminal of the present embodiment is in the “apparent power OFF state”, the answering machine service for the call to the mobile phone terminal is started up. Has been made. For this reason, for example, even when the third party makes a call to the mobile phone terminal and tries to check whether the terminal is really turned off, it is connected to the answering service. It is possible to make a third party think that the terminal is in a power-off state.

  In addition, according to the mobile phone terminal of the present embodiment, remote control such as power ON / OFF is enabled by the control information from the administrator side. For example, a missing person intentionally or mistakenly turns off the power. Even when the button is operated, the power can be forcibly turned on.

  The above description of the embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made according to the design or the like as long as the technical idea according to the present invention is not deviated.

  The present invention is not limited to a mobile phone terminal, and can be applied to various mobile communication terminals such as a PDA (Personal Digital Assistant), a car navigation device, and a portable video game device having a communication function.
