<Embodiment 1>
A first embodiment according to the present invention will be described. FIG. 1 is a block diagram of a portable terminal 1 according to the present embodiment. The mobile terminal 1 includes a wireless communication unit 11, an operation unit 12, a communication determination unit 13, and an execution unit 14. The mobile terminal 1 is, for example, a mobile phone, a mobile music player, a mobile game machine, a tablet PC (Personal Computer), or the like.

  The wireless communication unit 11 communicates with a base station and other terminals via close proximity wireless communication such as Bluetooth (registered trademark) or WiFi, or a public communication network. For example, the wireless communication unit 11 performs transmission / reception of audio signals, transmission / reception of mails, and the like.

  The operation unit 12 is an interface such as a button, a cross key, or a touch panel. The user inputs information to the mobile terminal 1 by operating the operation unit 12.

  The communication determination unit 13 determines whether or not the wireless communication unit 11 is communicating with the base station via the public communication network. The communication determination unit 13 determines that communication with the base station is not performed, for example, when the mobile terminal 1 is turned off or out of the communication range. The communication determination unit 13 notifies the execution unit 14 of the determination result.

  The execution unit 14 is a control unit including, for example, a CPU (Central Processing Unit), and controls the operation of the mobile terminal 1 according to a control program stored in a memory (not shown). When the communication determination unit 13 determines that communication between the mobile phone 1 and the base station has not been performed for a predetermined time, the execution unit 14 executes the lost mode. The predetermined time is, for example, several hours, half a day (12 hours), one day (24 hours), or the like, and can be set as appropriate by the user.

  Here, the lost mode is a mode for causing the mobile terminal 1 to execute a preset operation regardless of the operation of the operation unit 12. In the lost mode, the execution unit 14 transfers the memory data of the mobile terminal 1 to an external device, deletes the memory data, or stores the location information of the mobile terminal 1 regardless of the operation of the operation unit 12. Acquire and send the location information to an external device or respond to an incoming call from an external telephone. By executing the lost mode, the portable terminal 1 automatically executes the above operation by the execution unit 14 even when the operation unit 12 is not operated.

  Subsequently, an operation example of the mobile terminal 1 according to the present embodiment will be described. First, it is assumed that the mobile terminal 1 is lost or stolen. At this time, the communication determination unit 13 periodically checks the communication status of the mobile terminal 1. When communication between the mobile terminal 1 and the base station is not performed due to a power-off of the mobile terminal 1 or the like, the communication determination unit 13 determines that communication is not performed, and executes the determination result. 14 is notified.

  The execution unit 14 executes the lost mode when the communication determination unit 13 determines that the mobile terminal 1 is not continuously communicating for a preset time. Thereby, the portable terminal 1 can automatically execute a preset operation regardless of the operation of the operation unit 12.

  As described above, according to the configuration of the mobile terminal 1 according to the present embodiment, the communication determination unit 13 determines the presence / absence of communication between the mobile terminal 1 and the base station. And when communication with the portable terminal 1 and a base station is not performed, the execution part 14 performs loss mode. Thereby, the portable terminal 1 can automatically perform a preset operation. Therefore, after the mobile terminal 1 is lost, even if the user does not give any instruction to the mobile terminal 1, the mobile terminal 1 can be automatically used for protecting user data such as a telephone directory or searching for the mobile terminal 1. Operations such as data transmission can be performed. As a result, it is possible to quickly cope with loss or theft.

<Embodiment 2>
Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, a mobile phone 2 will be described as an example of a mobile terminal. First, the configuration of the entire system including the mobile phone 2 according to the present embodiment will be described. FIG. 2 is a diagram showing the overall configuration of the system. The mobile phone 2 communicates with a base station 91 and a GPS (Global Positioning System) satellite 92, and can acquire position information. The mobile phone 2 can communicate with other preset telephones 93 and an external PC 94, and can transmit and receive image data and audio data.

  The detailed configuration of the mobile phone 2 will be described with reference to FIG. FIG. 3 is a block diagram of the mobile phone 2. In addition to the wireless communication unit 11 and the operation unit 12, the mobile phone 2 includes a GPS processing unit 21, a camera 22, a timer 23, a lost mode control unit (corresponding to the communication determination unit 13 and the execution unit 14) 24, User data 25 and lost mode control data 26 are provided. Note that the configurations of the wireless communication unit 11 and the operation unit 12 are the same as those of the mobile terminal 1, and thus description thereof will be omitted as appropriate.

  The wireless communication unit 11 has an antenna (not shown) and performs normal mobile phone communication (telephone communication, videophone communication, mail transmission / reception, etc.). Further, it communicates with the base station 91 to acquire the position information of the mobile phone 2.

  The GPS processing unit 21 acquires position information of the mobile phone 2 from the GPS satellite 92. As described above, the location information of the mobile phone 2 can also be acquired from the base station 91. Therefore, the mobile phone 2 does not necessarily have to include the GPS processing unit 21.

  The camera 22 (imaging means) shoots a user at the time of a videophone call and shoots a still image or a moving image. The timer 23 measures time. Note that the time counted by the timer 23 may be reset by a user operation.

  The lost mode control unit 24 includes, for example, a CPU, and controls the operation of the mobile phone 2 in the lost mode. In other words, the lost mode control unit 24 controls the operation of the mobile phone 2 in the lost mode based on the lost mode execution process and preset information.

  The user data 25 and the lost mode control data 26 are stored in, for example, a RAM (Random Access Memory) or a ROM (Read Only Memory). The user data 25 is data such as user personal information, a phone book, a call history, and sent / received mail. On the other hand, the lost mode control data 26 is data that the lost mode control unit 24 refers to during the lost mode, and is information regarding a control program for controlling the operation of the mobile phone 2 in the lost mode. .

  Note that the user data 25 and the lost mode control data 26 are preferably managed separately, for example, by dividing the storage memory. This is because, from the viewpoint of security and personal information protection, only the user data of the mobile phone 2 can be easily transferred and deleted when lost.

  Next, the operation of the mobile phone 2 according to the present embodiment will be described. A sequence diagram showing the operation of the mobile phone 2 is shown in FIG. First, the user loses or steals the mobile phone 2 (step S11).

  The lost mode control unit 24 determines whether or not the wireless communication unit 11 is communicating with the base station 91 (step S12). Note that the communication determination process by the lost mode control unit 24 is not performed for the first time after the mobile phone 2 is lost, but before the loss or the like.

  The lost mode control unit 24 determines whether or not the wireless communication unit 11 and the base station 91 are continuously communicating for a predetermined time or more (step S13). Whether or not communication is regularly performed is determined by, for example, determining whether or not communication is performed at predetermined time intervals, and when there is no communication continuously for a predetermined number of times, communication is not continuously performed. Is determined. When communication between the wireless communication unit 11 and the base station 91 is performed periodically (step S13: No), the lost mode control unit 24 again checks whether there is communication between the wireless communication unit 11 and the base station 91. A determination process is performed (step S12).

  When the communication with the base station 91 by the wireless communication unit 11 is not continuously performed for a predetermined time (step S13: Yes), the lost mode control unit 24 executes the lost mode (step S14). Thereby, the cellular phone 2 is automatically operated by the lost mode control unit 24 regardless of the user's operation.

  After shifting to the lost mode, the lost mode control unit 24 performs a backup process of the user data 25 (step S15). Specifically, the lost mode control unit 24 transmits the user data 25 of the mobile phone 2 to a preset external device (for example, the home PC 94 in FIG. 2). Thereby, even if the lost mobile phone 1 is not found, the user can use the user data 25 stored in the mobile phone 1. When the backup process in step S15 is completed, the lost mode control unit 24 deletes the user data 25 (step S16).

  The transfer process (step S15) and the erasure process (step S16) are automatically executed by the lost mode control unit 24. Therefore, the transfer process and the erasure process are executed without operating the operation unit 12 of the mobile phone 2.

  As described above, according to the configuration of the mobile phone 2 according to the present embodiment, when the mobile phone 2 and the base station 91 are not communicating for a predetermined time or longer, the lost mode control unit 24 Performs the lost mode. Then, after shifting to the lost mode, the lost mode control unit 24 transfers the user data 25 and then deletes the user data 25 from the mobile phone 2. Thereby, since it becomes impossible to refer to user data from the mobile phone 2, it is possible to prevent user data from being misused. Of course, since the process of the lost mode control unit 24 is executed without waiting for an instruction such as a remote operation from the user, it is possible to quickly deal with the lost or stolen mobile phone 2.

  Further, the lost mode control unit 24 may not accept an input from the operation unit 12 in the lost mode. This can prevent the transfer process and the erasure process from being hindered. Therefore, the user data 25 can be reliably protected.

  In addition, the lost mode control unit 24 may control the mobile phone 2 so that a call can be made only to a preset telephone number in the lost mode. For example, deletion of telephone extension data other than a preset telephone number is performed. The preset telephone number is the user's home phone number or the user's family mobile phone number. Thereby, the third party who acquired the lost mobile phone 2 can contact only the user. Therefore, a third party can inform the user of the location of the mobile phone 2. In addition, since a telephone number other than a preset telephone number cannot be transmitted, misuse of a third party can be prevented.

(Modification 1)
A modification 1 of the mobile phone 2 according to the present embodiment will be described. FIG. 5 shows a sequence diagram illustrating the operation of the mobile phone 2 according to the first modification. The processing operation up to the execution of the lost mode (step S14) is the same as the operation described with reference to FIG.

  During execution of the lost mode, the user notices that the mobile phone 2 has been lost, and makes a call to the mobile phone 2 from a preset telephone number. Then, the mobile phone 2 receives an incoming call from a preset telephone number (step S21). The preset telephone number is, for example, the telephone number of the telephone 93 at home, the mobile phone number of the user's family, etc., which is set in advance by the user.

  When the lost mode control unit 24 receives an incoming call from a preset telephone number, the lost mode control unit 24 responds to the incoming call regardless of the operation of the operation unit 12. Thereby, the mobile phone 2 shifts to a call state with the user (step S22). That is, when the lost mode control unit 24 receives an incoming call from a preset telephone number, the lost mode control unit 24 automatically starts a call with the user even if the operation start operation is not performed in the operation unit 12. Thereby, a user and the mobile telephone 2 will be in a telephone call state (step S23).

  The call with the user may be a voice call or a TV phone. In the case of a videophone, the lost mode control unit 24 activates the camera 22 in addition to the incoming call response process, and transmits the video acquired by the camera 22 to the user.

Note that the preset mail address is, for example, the mail address of the home PC 94 or the mail address of the user's family mobile phone, which is set in advance by the user. Further, the content of the email transmitted by the user may be a blank email, or a predetermined title or text may be input.

  When the lost mode control unit 24 receives a mail from a preset mail address, the lost mode control unit 24 activates the camera 22 and images the surroundings of the mobile phone 2. At the same time, the lost mode control unit 24 causes the GPS processing unit 21 to acquire the current location information of the mobile phone 2 (step S32). The imaging process and the position information acquisition process are automatically executed by the lost mode control unit 24 regardless of the operation of the operation unit 12. Accordingly, the lost mode control unit 24 acquires image data around the mobile phone 2 and position information of the mobile phone 2.

  When the lost mode control unit 24 acquires the image data and the position information, the lost mode control unit 24 sends the mail with the image data and the position information attached to a preset mail address (step S33). The destination at this time may be the same mail address as the sender of the received mail in step S31, or may be a different mail address from the sender.

  As described above, according to the configuration of the modification 2 according to the present embodiment, when the lost mode control unit 24 receives a mail from a preset mail address, the information around the mobile phone 2 is automatically set. And the location information of the mobile phone 2 is acquired, and the information is transmitted to a preset mail address. Therefore, the user can acquire real-time information at any time. Thereby, the user can specify the position of the mobile phone 2 based on the image data and the position information sent from the mobile phone 2.

(Modification 3)

FIG. 7 is a sequence diagram showing the operation of the mobile phone 2 according to the third modification. The processing operation up to the execution of the lost mode (step S14) is the same as the operation described with reference to FIG.

  When the lost mode is executed, the lost mode control unit 24 causes the timer 23 to start measuring time (step S41). Thereafter, the lost mode control unit 24 causes the camera 22 to execute an imaging process and causes the GPS processing unit 21 to acquire position information (step S42).

  When the lost mode control unit 24 acquires the image data and the position information, the lost mode control unit 24 sends the mail with the image data and the position information attached to a preset mail address (step S33).

  Thereafter, when the timer 23 measures a preset time, the timer 23 stops counting (step S44). Here, the predetermined time is, for example, one hour and can be arbitrarily set by the user.

  Then, the lost mode control unit 24 causes the timer 23 to start counting again (step S41). Then, the lost mode control unit 24 acquires the image data and the position information again (step S42), and transmits it to a preset mail address (step S43).

  As described above, according to the configuration of the third modification according to the present embodiment, the lost mode control unit 24 automatically acquires the image data captured by the camera 22 and the GPS processing unit 21 at predetermined time intervals. The set position information is transmitted to a preset mail address. Thereby, the user can periodically acquire information around the mobile phone 2 and position information of the mobile phone 2. Therefore, the user can determine whether or not the mobile phone 2 is in a moving state by comparing information transmitted from the mobile phone 2. Moreover, since information is sent regularly, the user can always acquire the latest information.

(Modification 4)
A modification 4 of the mobile phone 2 according to the present embodiment will be described. FIG. 8 shows a sequence diagram illustrating the operation of the mobile phone 2 according to the fourth modification. The processing operation up to the execution of the lost mode (step S14) is the same as the operation described with reference to FIG.

  When the loss mode is executed, the loss mode control unit 24 causes the camera 22 to execute an imaging process at regular time intervals and causes the GPS processing unit 21 to acquire position information (step S51). Note that the processing in step S51 may be realized by the method shown in FIG.

  Next, the lost mode control unit 24 determines whether or not the position of the mobile phone 2 has moved by a certain distance or more based on the acquired position information (step S52). Here, the predetermined distance is 1 km, for example, and can be set as appropriate by the user. Whether or not it has moved over a certain distance is determined, for example, by storing position information in a memory (not shown) and comparing the position information acquired at the next timing with the position information stored in the memory. it can.

  When the position of the mobile phone 2 has not moved more than a certain distance (step S52: No), the lost mode control unit 24 obtains position information at regular intervals again (step S51).

  On the other hand, when the mobile phone 2 has moved beyond a certain distance (step S52: Yes), the lost mode control unit 24 transmits the acquired image data and position information to a preset mail address (step S53). Then, the lost mode control unit 24 acquires the position information again at regular intervals (step S51).

  As described above, according to the configuration of the modification 3 according to the present embodiment, the lost mode control unit 24 performs the image data captured by the camera 22 and the GPS processing when the mobile phone 2 moves more than a certain distance. The position information acquired by the unit 21 is transmitted to a preset mail address. Thereby, only when the position of the mobile phone 2 is moved, the surrounding information and the position information are notified to the user. As a result, the user can efficiently acquire information on the mobile phone 2.

<Embodiment 3>

  The lost mode control unit 24 determines whether or not a predetermined time has elapsed (step S73). Here, the predetermined time is, for example, half a day (12 hours), one day (24 hours), or the like, and can be set as appropriate by the user. If the time measured by the timer 23 has not passed the predetermined time (step S73: No), the lost mode control unit 24 obtains the time measured by the timer 23 again (step S72).

  On the other hand, if the time measured by the timer 23 has passed the predetermined time (step S73: Yes), in other words, if the user has not reset the time measured by the predetermined time timer 23, the lost mode control unit 24 The lost mode is executed (step S74). Thereby, the cellular phone 3 is automatically operated by the lost mode control unit 24 regardless of the user's operation.

  As described above, according to the configuration of the mobile phone 4 according to the present embodiment, the lost mode control unit 24 executes the lost mode when the time count of the timer 23 is not reset for a predetermined time by the user. That is, when the time measured by the timer 23 is not reset, the lost mode is automatically executed without waiting for an instruction from the user such as a remote operation. Therefore, it is possible to quickly respond to the lost or stolen mobile phone 4.

  Of course, as for the operation of the mobile phone 4 after execution of the lost mode, various processes described in the second embodiment can be appropriately selected or combined. Therefore, the description of the operation after executing the lost mode is omitted.
