  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. Furthermore, the current position (latitude / longitude) is received using a GPS satellite by the operation of the current position detector 26 described later.

  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 made of, for example, an SRAM (Static Randum Access Memory), and can store communication history data, registration data, and transfer destination data. The communication history data is data obtained by leaving a predetermined number or number of days of outgoing / incoming history and browsing URL (Uniform Resource Locator) history. The registered data is data registered by the user, such as a telephone book, an e-mail address book, and a URL registered in favorites. Further, the transfer destination data can be an e-mail address of the other party when the data of the own device is automatically transferred.

  The display unit 24 displays a telephone number, the name of the other party, an e-mail address, the contents of the e-mail, a homepage image, 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 current position detection unit 26 includes a GPS (Global Positioning System) receiver that detects the current position.

  Next, the auto lock function will be described. FIG. 2 is a flowchart showing the operation of the mobile phone 10. First, in step S10, when the operation unit 25 is operated and there is a communication instruction such as a telephone call instruction or an internet connection instruction, the process proceeds to step S11 to determine whether the auto-lock function is ON or OFF. ON / OFF switching can be performed by a predetermined operation of the operation unit 25 such as input of a password.

  If the auto-lock function is OFF in step S11, the process proceeds to step S12 and normal communication processing is performed. On the other hand, if the auto lock function is ON in step S11, the process proceeds to step S13.

  In step S <b> 12, the control circuit 21 performs communication processing. If there is an on-hook operation on the partner side or an on-hook operation from the operation unit 25, the control circuit 21 ends the communication processing and shifts to a standby state.

  In step S13, it is determined whether or not the communication destination instructed for communication is in communication history data or registration data. If the communication destination is in the communication history data or registration data in step S13, the process proceeds to step S12 to perform normal communication processing. On the other hand, if the communication destination is not in the communication history data or the registration data in step S13, the process proceeds to step S14.

  In step S14, the communication instruction performed in step S10 is invalidated. That is, communication processing is not executed. Then, it progresses to step S15 and invalidates operation of the operation part 25 after that. That is, the operation unit 25 is locked. However, the password input for unlocking is accepted. Next, the process proceeds to step S16 to transfer the registration data to one or more predetermined destinations. The communication history data and the current position of the own device may be transferred together. Here, the predetermined destination can be an e-mail address preset by the user. Send data as an email attachment. One or more predetermined destinations can be set, and a personal computer or other mobile phone that is owned may be designated.

  Next, it progresses to step S17 and deletes communication history data and registration data. Thus, the automatic lock of the mobile phone 10 is completed. Note that this lock state is released by inputting the personal identification number.

  Further, after the process of step S17 is completed, the apparatus of the present embodiment shifts to a standby state.

In step S17, the data to be erased is communication history data and registration data, but personal data of both the communication history data and the registration data is not erased, but communication history data (incoming history, transmission history) is called. Only personal data may be deleted, or only registered data (for example, telephone book data such as a telephone number, name, and mail address, or personal data such as a personal telephone number may be deleted).

  Note that step 16 and / or step S17 are not necessarily required for the auto-lock function, and only the processing from step S10 to step S15 may be performed. Further, when the process of step S17 is performed, step S15 is not necessarily required. In that case, it is sufficient to invalidate the subsequent communication instruction.

  For example, when the mobile phone 10 is stolen and the theft person enters a telephone number to make a call and the auto-lock function is turned on in advance, the operation unit is locked without making a call. Then, the registration data, the current position, etc. are transferred, and the data in the mobile phone 10 is deleted. Therefore, even if the user does not readily notice that the mobile phone 10 has been stolen, there is no possibility of being misused during that time.

  Thus, even if the cellular phone 10 is stolen, the communication instruction to the communication destination not included in the communication history data or the registration data is invalidated, and the mobile phone 10 is not illegally transmitted. So security is high. Furthermore, by deleting the communication history data and registration data at the same time as auto-locking, personal information will not be leaked even if the lock is released. Furthermore, by transferring the registration data to one or more predetermined destinations, the registration data can be protected even when the data is erased or the mobile phone 10 does not return to the hand. In addition, by transferring the data of the current position to one or more predetermined destinations at the same time as auto-locking, the user can know the location of the mobile phone 10 and become a clue to search.

  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).
