Description

  The present invention relates to a portable mobile communication device.

  In recent years, mobile communication devices such as mobile phones have become widespread. Along with this, the age of users has decreased and has spread to children. For example, there is a usage in which a child who goes out for safety has a mobile phone so that he can always be in contact with his / her home.

  When a child has a mobile phone as described above, a function (referred to as a junior mode or a kids mode) for restricting (locking) each operation is generally used. Using this function, incoming calls can be unlimited and outgoing calls can be made only to specific phone numbers. As a result, when the child is given it, it is not possible to make a mischief call by setting it so that the call can be made only at home. In addition, if it is given to an employee, it cannot be used for private use by setting it so that it can only be sent to the company.

In addition, mobile phones are likely to be stolen or lost due to the nature of being used outdoors. If it is used by a theft, the usage fee will be charged by the operator. Therefore, Patent Document 1 discloses a security system for a portable communication device and a portable communication device capable of performing various operations such as dial lock and telephone directory lock by remote operation from other communication devices. . Thereby, even if a device that is not key-locked is stolen, it can be key-locked by remote operation from another telephone.
Japanese Patent Laid-Open No. 11-32369

  Generally, a password is used to set / cancel the function for restricting the above operations and the function disclosed in Patent Document 1. For example, if a four-digit number is used as the password, the password can be known by inputting 10,000 times at the maximum. Therefore, once the child or employee knows the password, this function is meaningless unless the password is changed. This is because the child or the employee needs to release the lock at the time of use and to lock again when returning to the owner of the parent or the company.

  Therefore, an object of the present invention is to provide a mobile communication device that allows an owner to check that the operation restriction lock has been released.

  The present invention includes a display unit and an operation unit that receives an input operation, and can restrict or release a specific operation based on the operation from the operation unit. When a specific operation is restricted based on the operation, an operation of displaying the first mark on the display unit and releasing the restriction from the operation unit in a state where the first mark is displayed on the display unit. If there is, the restriction is released, and when the restriction is applied again in the released state, a predetermined second mark different from the first mark is displayed on the display unit. To do.

The present invention displays the first mark on the display unit when a specific function is locked, and displays the second mark on the display unit when the specific function is unlocked and the specific function is locked again. Is. For this reason, even if the parent gives the mobile communication device to the child, the parent can know that the child has released the lock without permission. is there.
Also, whether or not it has been released is not displayed in characters, but is displayed as a mark, so that the child may be informed that the child has been unlocked, It is possible to avoid destruction or disposal.

  Hereinafter, a mobile phone will be described as an example of the mobile communication device. FIG. 1 is a block diagram showing the configuration of the mobile phone 10.

  In FIG. 1, a communication unit 11 transmits a signal from a baseband unit 13 (to be described later) for a voice call to a base station (not shown) via an antenna 12, and transmits a radio wave from the base station via an antenna 12. To receive. In addition, it connects to the Internet network (not shown) to connect to a home page and exchanges e-mails.

  The baseband unit 13 includes a CDMA (Code Division Multiple Access) processing circuit 13a and an audio codec processing circuit 13b. The CDMA processing circuit 13a performs code division multiple access, scrambling, error control, timing detection, and the like. On the other hand, the audio codec processing circuit 13b compresses (encodes) and expands (decodes) audio, converts analog signals and digital signals, and receives an incoming sound volume and a microphone by an internal amplifier circuit (not shown). Change the sensitivity.

  The speaker 14 used for a call converts the electrical signal from the switching circuit 20 amplified by the amplifier 15 into an audio signal. The microphone 16 used for a call converts an audio signal into an electric signal and outputs it to the amplifier 17. The electrical signal amplified by the amplifier 17 is output to the switching circuit 20. Further, the speaker 18 outputs a ringing tone or a melody amplified by the amplifier 19.

  The switching circuit 20 turns on / off the connection between the three amplifiers 15, 17, 19 and the baseband unit 13 under the control of the control circuit 21 described later. Note that these amplifier circuits have a fixed gain, and cannot change the reception volume, key click volume, and microphone sensitivity. The voice codec 13 a of the baseband unit 13 changes the reception volume, key click volume, and microphone sensitivity under the control of the control circuit 21.

  A control circuit 21 composed of a microprocessor controls each unit based on a system program stored in a first storage unit 22 composed of, for example, a ROM (Read Only Memory).

  The second storage unit 23 is composed of, for example, an SRAM (Static Random Access Memory), phone book data combining the other party's telephone number and name, e-mail address book data combining the other party's e-mail address and name, and transmission.・ Communication history data that keeps a predetermined number or number of days of URL (Uniform Resource Locator) history of incoming or browsed, URL data registered in favorites, PIN code for lock or unlock to restrict the operation of a specific function Etc. are stored.

  The display unit 24 displays a telephone number, a name of the other party, an e-mail address, an e-mail content, a homepage image, a counter value to be described later, an image representing various functions, and the like.

  The operation unit 25 includes various keys such as a call key, an off key, a numeric keypad, a power key, a function key, an e-mail start key, and an Internet connection key.

  The counter 26 counts the number of times of locking or releasing for operation limitation. Note that the numerical value of the counter 26 may be reset or may not be reset.

  Next, a function for restricting each operation, that is, a function for locking a specific function (hereinafter referred to as a kids mode) will be described. FIG. 2 is a flowchart showing the operation of the mobile phone 10 relating to the kids mode. First, when the operation unit 25 is operated in step S10 and a password for setting the kids mode is input, the process proceeds to step S11 and the input password and the password registered in the second storage unit 23 are equal. It is determined whether or not it is done. If the passwords do not match in step S11, the process returns to step S10 and waits for the passwords to be input again. On the other hand, if the passwords match in step S11, the process proceeds to step S12 and the control circuit 21 sets the kids mode.

  In kids mode, incoming calls are unlimited and outgoing calls are only allowed to a specific (eg home) phone number. Furthermore, a terminal that can use the Internet may be accessible only to a specific URL (for example, a URL registered as a favorite). It may also be possible to send only to a specific e-mail address.

  In step S13, it is determined whether or not the counter value is zero. Note that the counter (owner) resets the counter value before setting the kids mode. The counter can be reset by inputting a password for resetting the counter.

  When the value of the counter is 0 in step S13, the process proceeds to step S14 and the first mark is displayed on the display unit 24. Thereby, the user can visually recognize that it is in the kids mode. FIG. 3 shows a screen when the kids mode is set and the counter is zero. A first mark 31 is displayed at the bottom of the screen 30.

  Next, the process proceeds from step S14 to step S16, and when the password for canceling the kids mode is input by the child or the like (the borrower), the process proceeds to step S17 and is registered in the second storage unit 23. It is determined whether or not the passwords match. The password for setting and canceling the kids mode may be the same or different. If the passwords do not match at step S17, the process returns to step S16 and waits for the password to be input again. On the other hand, if the passwords match in step S17, the process proceeds to step S18, and the control circuit 21 cancels the kids mode.

  In step S19, 1 is added to the counter 26. In step S20, the displayed mark is erased. Then, it returns to step S10. Returning to step S10, when a password is input by a child or the like, the kids mode is set again in step S12, and the process proceeds to step S13 to determine the value of the counter 26. Since 1 is added to the counter in step S19, the value of the counter 26 is 1 or more. In this case, the process proceeds from step S13 to step S15, and the second mark is displayed on the display unit 24. Thereby, the user can visually recognize that the kids mode is set again after the kids mode is once canceled. FIG. 4 shows a screen when the kids mode is set and the counter is not zero. A second mark 32 is displayed at the bottom of the screen 30. The second mark 32 and the first mark 31 are distinguished by changing the design or changing the position.

  Note that three or more marks such as the third mark may be displayed according to the value of the counter 26.

  For example, if you want to bring the mobile phone 10 to a child who goes out, set it to Kids mode. If your child should unlock the Kids mode by decrypting the PIN and use it freely, set it to Kids mode again. Even so, the parent can know that the child has once canceled the kids mode since the second mark 32 is displayed. In this case, it is possible to change the personal identification number or prevent the child from holding the mobile phone 10.

  Next, another embodiment of the kids mode will be described. FIG. 5 is a flowchart showing the operation of the mobile phone 10 relating to another kids mode. In the above embodiment, the value of the counter 26 can be reset. When the parent or the like sets the kids mode, it is necessary to reset the counter 26 in advance, but in this embodiment, the value of the counter 26 cannot be reset. To do.

  First, when the operation unit 25 is operated in step S30 and the password for setting the kids mode is input, the process proceeds to step S31 and the input password and the password registered in the second storage unit 23 are equal. It is determined whether or not it is done. If the passwords do not match in step S31, the process returns to step S30 and waits for the password to be input again. On the other hand, if the passwords match in step S31, the process proceeds to step S32 and the control circuit 21 sets the kids mode.

  In step S33, 1 is added to the value of the counter 26. In step S34, the counter value is displayed on the display unit 24. Thereby, the user can visually recognize that the mode is the kids mode and the current value of the counter 26.

  Next, the process proceeds from step S34 to step S35, and when a password for canceling the kids mode is input by a child or the like, the process proceeds to step S36 and the input password and the password registered in the second storage unit 23 are obtained. It is determined whether or not they match. The password for setting and canceling the kids mode may be the same or different. If the passwords do not match in step S36, the process returns to step S35 and waits for the passwords to be input again. On the other hand, if the passwords match in step S36, the process proceeds to step S37, and the control circuit 21 cancels the kids mode.

  In step S38, the displayed mark is erased. Then, it returns to step S30. When returning to step S30 and proceeding to step S34, 1 is added to the value of the counter 26 in step S33, so 1 is added to the value of the counter 26 displayed. In this way, by increasing the value of the displayed counter 26, the user can visually recognize that the kids mode is set again after the kids mode is canceled. Further, since the value of the counter 26 cannot be reset, there is no worry that the child changes the value of the counter 26 without permission.

  For example, if you want to bring the mobile phone 10 to a child who goes out, set it to Kids mode. If your child should unlock the Kids mode by decrypting the PIN and use it freely, set it to Kids mode again. Even so, the parent can know how many times the child has canceled the kids mode because the value of the counter 26 has increased. In this case, it is possible to change the personal identification number or prevent the child from holding the mobile phone 10.

  What is displayed in steps S14, S15, and S34 of the above two embodiments is not particularly limited in the display image as long as it can be visually confirmed that the kids mode is set and the kids mode is once released. You may change the background color, design, etc. The value of the counter 26 may be separately confirmed on a counter display screen.

  In this way, the present invention provides the mobile communication device with the counter 26 for counting the setting or release of the kids mode, so that the owner refers to the value of the counter 26 and the display that changes based on the value of the counter 26 without permission. You can check that the kids mode has been canceled.

  The mobile communication device of the present invention can be used for mobile terminals such as mobile phones, PHS, car phones, PDAs (Personal Digital Assistants).
