However, even if a child has a portable terminal equipped with a current location notification function, when the child is kidnapped, the kidnapper turns off the power of the portable terminal and the current location is another communication device. It is easily assumed not to be notified. Alternatively, the kidnapper may remove the battery of the portable terminal.
Accordingly, an object of the present invention is to provide a portable terminal and a location information transmission method capable of transmitting the current location of the own device to another communication device even when the power of the own device is turned off by the kidnapper. To do. A second object of the present invention is to provide a portable terminal and a location information transmission method capable of transmitting the current location of the own device to another communication device even when the battery of the own device is removed by the kidnapper.

  In order to achieve the above object, a portable terminal according to the present invention includes a receiving unit that receives a power-off instruction to turn off the power of the own device, an acquiring unit that acquires position information indicating the current location of the own device, and a communication And a control unit that causes the communication unit to transmit the position information to another communication device via a network after the receiving unit receives the power-off instruction, and causes the acquisition unit to acquire the position information. It is characterized by providing.

  In order to achieve the above object, a location information transmission method according to the present invention is a location information transmission method used for a portable terminal, and receives a power-off instruction to turn off the power of the device. Including a step of acquiring position information indicating the current location of the own device, and a step of transmitting position information to another communication device via a network after receiving the position information when receiving a power-off instruction. Features.

  Here, “turning off the power” is the same as an electronic device having a general power on / off function, and does not stop the power supply to all the functional units, but the power to the main functional units. It means to stop the supply. Generally, even when the power of the electronic device is turned off, the control unit that controls each functional unit of the electronic device or a part thereof, the part of the operation unit that receives an instruction to turn on the power, and the time are counted. The power supply to the timekeeping unit to be performed is not stopped.

  When the portable terminal according to the present invention receives a power-off instruction or detects the removal of the battery or the battery lid, the portable terminal transmits the position information to another communication device due to this, for example, the portable terminal If the child holding the kidnapper is kidnapped, and the kidnapper performs an operation to turn off the power or intends to remove the battery, the current location of the kidnapper may become another communication device. Will be informed to the parents and police of the kidnapped children sent to and helped to resolve the case early.

  Here, the portable terminal further includes a timing unit that counts time, and the control unit causes the communication unit to transmit the position information to another communication device, and then, based on the power-off instruction, Control is performed to stop power supply to a part of the own machine including the acquisition unit and the communication unit, and the time measuring unit counts a predetermined time after the power supply is stopped, and when a predetermined time has elapsed. This is notified to the control means, and the control means further performs control to resume power supply to a part of its own device including the acquisition means and the communication means by receiving the notification from the time measuring means. Thereafter, the acquisition unit may acquire position information, and the communication unit may transmit the position information to another communication device via a network.

As a result, even if the location information transmitted before the power is turned off does not reach another communication device for some reason such as a communication failure, the power supply is resumed and the location information is Since the position information is acquired and transmitted to the other communication apparatus via the network, the position information can be reliably transmitted to the other communication apparatus.
In addition, the portable terminal further includes a timing unit that counts time, and the control unit stops power supply to a part of the own unit including the acquisition unit and the communication unit based on the power-off instruction. The timing means counts a predetermined time after the power supply is stopped, and notifies the control means when the predetermined time has elapsed, and the control means further includes the timing Control to resume power supply to a part of the own machine including the acquisition unit and the communication unit by receiving the notification from the unit, and then cause the acquisition unit to acquire position information and cause the communication unit to acquire the position. Information may be transmitted to another communication device via a network.

  Since it is generally assumed that it takes time to acquire location information, if a power-off instruction is received, the power is immediately turned off, and then the location information is acquired after the supply of power is resumed. By transmitting the position information to another communication device via the network, for example, when a kidnapper tries to turn off the mobile terminal by pressing the power button, Since the power is cut off as if it were a street time, the kidnapper would not be suspicious.

  Here, the receiving means further receives an emergency mode setting instruction for switching the own mode from the normal mode to the emergency mode, and the control means further sets the own apparatus to the emergency mode based on the emergency mode setting instruction. The time counting means counts a predetermined time after the power supply is stopped only when the self-machine is set to the emergency mode, and notifies the control means when the predetermined time has passed. The control means further performs control to resume power supply to a part of the own machine including the acquisition means and the communication means by receiving the notification from the time measuring means, and then to the acquisition means. Position information may be acquired, and the communication unit may transmit the position information to another communication device via a network.

With this configuration, the user can switch the mode of the user device to either the normal mode or the emergency mode, and the portable terminal performs the above-described operation only when the user device is set to the emergency mode. Therefore, it is possible to prevent the location information from being inadvertently transmitted to another communication device.

<Operation>
The mobile phone 1 with a GPS function has an emergency mode setting function as described above.

FIG. 3 is a flowchart used to explain emergency mode setting processing.
First, when the mobile phone with GPS function 1 receives an instruction to display an emergency mode setting screen from the user via the operation unit 2, the control unit 14 stores an emergency mode setting program stored in the storage unit 15. The emergency mode setting screen is displayed on the display unit 3 (step S1).

Next, when an instruction to turn on the emergency mode is received by a user operation on the operation unit 2 (step S2: YES), the control unit 14 stores flag information indicating that the emergency mode is on in the storage unit 15 To remember. That is, the mode of the mobile phone with GPS function 1 is set as an emergency mode (step S3).
Subsequently, the setting of the destination mail address for notifying the current location in the emergency mode is received and set from the user (step S4), and the process is terminated.

If the instruction to turn on the emergency mode is not accepted in step S2 (step S2: NO), the flag information is not stored in the storage unit 15 and is not in the emergency mode, that is, in the normal mode (step S5). ) To finish the process.
Next, position information transmission processing performed when the emergency mode is set will be described.

FIG. 4 is a flowchart used for explaining the position information transmission process in the emergency mode of the cellular phone 1 with a GPS function.
First, when the mobile phone 1 with GPS function is turned on, if the user presses the power button, that is, receives an instruction to turn off the power from the user (step S11: YES), the control unit 14 stores the information. It is checked whether flag information indicating that the emergency mode is on is stored in the unit 15, that is, whether or not the own device is set to the emergency mode (step S12).

  If the own device is set to the emergency mode (step S12: YES), the control unit 14 causes the GPS processing unit 7 to perform GPS positioning and obtains position information indicating the current location of the own device (step S13). . Subsequently, the control unit 14 creates an e-mail addressed to a preset e-mail address describing the position information, and transmits the e-mail via the wireless communication unit 5 (step S14).

Thereafter, the control unit 14 includes functional units other than the power supply circuit 11, the time measuring unit 12, and the control unit 14 illustrated in FIG. 2, that is, the operation unit 2, the display unit 3, the wireless communication unit 5, the GPS processing unit 7, and the speaker unit 8. Then, a power-off process for stopping the power supply to the microphone unit 9 and the storage unit 15 is performed (step S15).
The timing unit 12 starts timing after the power-off process is performed (step S16), and when a predetermined time (for example, 10 minutes) has elapsed (step S17: YES), the timing unit 12 notifies the control unit 14 to that effect. Notice.

The control unit 14 that has received the notification from the time measuring unit 12 performs a partial power-on process for resuming the power supply to some functional units of the own device (step S18).
Here, some of the functional units whose power supply is resumed are the wireless communication unit 5 and the GPS processing unit 7, and power supply to the operation unit 2, the display unit 3, the speaker unit 8, and the microphone unit 9 is performed. It will not resume. In this partial power-on process, the standby screen or the like is not displayed on the display unit 2 and no sound effect is generated at the time of startup. Therefore, it is easy for the kidnapper to resume power supply. Never noticed.

When the power supply is resumed, the control unit 14 returns to step S13 and repeats the operations of steps S13 to S18 shown in FIG.
In step S12, when the flag information is not stored in the storage unit 15, that is, when the emergency mode is not set (step S12: NO), the power-off process is performed as usual (step S19).

  As described above, if the mobile phone 1 with GPS function is set in the emergency mode in advance, the position information of the own device is acquired based on the power-off instruction, and the position information is set in advance. Since the e-mail addressed to the e-mail address is created and transmitted, if the child has the GPS function mobile phone 1 set in the emergency mode, the child is kidnapped by the kidnapper and the kidnapper Even if the mobile phone 1 with GPS function is turned off, the current location of its own device is transmitted to a preset mail address, for example, the mail address of the parent mobile phone. Useful for early resolution of incidents.

In addition, since the power supply to some functional units is resumed every predetermined time after the power-off process is performed, the position information is acquired again, and the position information is transmitted by e-mail repeatedly. If a child is kidnapped, he can grab his gait without being aware of the kidnapper.
<Modification>
As the position information transmission process performed when the mobile phone 1 with the GPS function is set to the emergency mode, the following modifications may be considered.

FIG. 5 is a flowchart used to describe a modification of the position information transmission process in the emergency mode of the cellular phone 1 with a GPS function.
First, when the mobile phone with GPS function 1 is turned on, if the user presses the power button, that is, receives an instruction to turn off the power from the user (step S21: YES), the control unit 14 stores the storage unit. It is checked whether flag information indicating that the emergency mode is on is stored in FIG. 15, that is, whether the emergency mode is set (step S22).

If the emergency mode is set (step S22: YES), the control unit 14 performs a power-off process for stopping the power supply to the functional units other than the power supply circuit 11, the time measuring unit 12, and the control unit 14 illustrated in FIG. (Step S23).
The timing unit 12 starts timing after the power-off process is performed (step S24), and when a predetermined time (for example, 10 minutes) has elapsed (step S25: YES), the timing unit 12 notifies the control unit 14 to that effect. Notice.

The control unit 14 that has received the notification from the time measuring unit 12 performs a partial power-on process for resuming the power supply to some of the functional units of the own device (step S26).
After resuming power supply to some of the functional units, the control unit 14 causes the GPS processing unit 7 to perform GPS positioning, and acquires position information indicating the current location of the own device (step S27). Subsequently, the control unit 14 creates an e-mail addressed to a preset e-mail address describing the position information, and transmits the e-mail via the wireless communication unit 5 (step S28).

The control unit 14 returns to step S23 and repeats the operations of step S23 to step S28 shown in FIG.
In step S22, when the flag information is not stored in the storage unit 15, that is, when the emergency mode is not set (step S22: NO), the power-off process is performed as usual (step S29).

The mobile phone 1 with GPS function of this modified example performs the power-off process without acquiring and transmitting the position information when the power button is pressed, and after a predetermined time has elapsed, The process is resumed, and a series of processes of acquiring position information and transmitting an e-mail including the position information is repeated.
The process of this modification takes into account that it takes time for the GPS processing unit 7 to acquire position information. If the time from when the kidnapper presses the power button until the mobile phone 1 with GPS function is turned off becomes longer, it is assumed that the kidnapper is suspicious. The power-off process is performed without acquiring the position information, and then the position information is acquired and transmitted after the partial power-on process for restarting the power supply.
