Description

  The present invention relates to a portable communication terminal, and more particularly to a portable communication terminal capable of remote operation.

  2. Description of the Related Art In recent years, mobile phones that are widely used can store telephone directory data including a destination telephone number and name, transmitted and received e-mail data, image data captured by a camera, and the like.

  In order to protect these data, the mobile phone has a lock function that permits access to data on the condition that authentication is performed using a password.

For this reason, even if the owner loses the mobile phone and the mobile phone is in the hands of a third party, the third party who does not know the password cannot view the data.
However, if the mobile phone is passed to a third party without the lock function being set on the mobile phone, the third party can view the data.
For this reason, a technique is known in which a lock function is effectively set even when a call is made from another telephone to the mobile telephone and the mobile telephone does not respond to the call (for example, Patent Document 1).

  Japanese Patent Laid-Open No. 2003-70063 (Patent Document 2) discloses that a data erasure command is transmitted from a center device to a mobile phone in order to protect the data stored in the mobile phone, thereby causing the mobile phone to erase the data. Technology is known.

  However, a data deletion command must be transmitted from the center device on the telephone network side, and data stored in the mobile phone cannot be easily deleted.

  The present invention has been made to solve the above-described problems, and one of the objects of the present invention is to provide a portable communication terminal capable of executing processing by remote control after being switched to the lock mode. It is.

  In order to achieve the above-described object, according to an aspect of the present invention, the mobile communication terminal includes an operation receiving unit that receives an input of an operation by a user, and a control unit that executes a process corresponding to the received operation The control means receives a mode switching means for switching to the lock mode by remote operation, and an operation input for causing the operation accepting means to execute a first process predetermined in the lock mode. A prohibiting means for prohibiting the execution of the first processing, an automatic response means for responding to the incoming call in response to an incoming call from a telephone assigned a predetermined telephone number in the lock mode, and a response And a second process executing means for executing the second process in response to receiving an instruction for executing the predetermined second process from the telephone set.

  According to this aspect, when the operation is switched to the lock mode by remote operation and an operation input for executing a predetermined first process is accepted in the lock mode, the execution of the first process is performed. In response to an incoming call from a predetermined telephone number, in response to the incoming call and receiving an instruction to execute a predetermined second process from the telephone that responded, The second process is executed.

  For this reason, when the lock mode is switched by remote operation, the first process is not executed even when an input of an operation for executing the predetermined first process is accepted, but from the telephone having the predetermined telephone number. When there is an instruction, the second process is executed.

  Therefore, it is possible to provide a mobile communication terminal that can execute processing by remote operation after being switched to the lock mode.

  Preferably, it further comprises an incoming call notification means for notifying an incoming call in response to an incoming call, and the control means is configured to notify an incoming call when an incoming call from a telephone assigned with a predetermined telephone number is detected in the lock mode. It further includes prohibition means for prohibiting notification by the means.

  According to this aspect, in the lock mode, since it is prohibited to notify an incoming call in response to an incoming call from a predetermined telephone number, the mobile communication terminal can be remotely connected without being noticed by a person who owns the mobile communication terminal. Can be operated.

  Preferably, when the control unit is in a state in which a call can be made by a response by the automatic response unit in the lock mode, an operation for ending the call ready state by the operation accepting unit or an operation for turning off the power supply Further included is a restricting means for maintaining a state in which a call can be made even if an input is received.

  According to this aspect, in the lock mode, when it is possible to talk, it is possible to talk even if an input of an operation for ending the talkable state or an operation for turning off the power is accepted. To maintain.

  For this reason, since the person who possesses the mobile communication terminal cannot end the call, the remote operation can be reliably executed.

  Preferably, in the lock mode, the control means may receive an operation input for turning off the power by the operation accepting means until the automatic answering means responds at least once and the call based on the response is terminated. Further included is a power-off limiting unit that does not turn off the power.

  According to this aspect, in the lock mode, the power is not turned off even if an input of an operation for turning off the power is accepted until the telephone call based on the response is completed at least once.

  Therefore, at least one remote operation is possible after switching to the lock mode.

  Preferably, a destination information storage unit that stores destination information is further provided, and the second process includes a process of erasing the destination information stored in the destination information storage unit.

  According to this aspect, the destination information can be erased by remote operation, so the destination information can be protected.

FIG. 1 is a perspective view showing an appearance of a mobile phone according to one embodiment of the present invention.
FIG. 1A shows the appearance of an open-style mobile phone, and FIG. 1B shows the appearance of a closed-style mobile phone.

  With reference to FIG. 1A and FIG. 1B, mobile phone 1 includes an operation side portion 3 and a display side portion 2. The operation side unit 3 includes an operation key 14 including a power key 14A, a numeric keypad, a call key, and the like, and a microphone 13 on the inner side surface, and a microphone terminal 16 and an earphone terminal 17 on the right side surface. In the display side section 2, a liquid crystal display (LCD) 15, a first speaker 11 constituting a receiver, and a camera 24 are arranged on the inner surface, and a camera 24A, a small LCD 15A, and a second speaker 12 are arranged outside. Located on the side. Although an example in which the mobile phone 1 includes the LCD 15 is shown here, an organic EL (ElectroLuminescence) display may be used instead of the LCD 15.

  The operation side unit 3 and the display side unit 2 are rotatably connected by a hinge mechanism, and the operation side unit 3 and the display side unit 2 can be opened and closed. When the mobile phone 1 is folded and the operation side portion 3 and the display side portion 2 are in the closed state, the state of the mobile phone 1 is the closed style, and the mobile phone 1 is opened to open the operation side portion 3 and the display side portion. The state of the mobile phone 1 when 2 is in the open state is the open style.

FIG. 2 is a functional block diagram illustrating an example of functions of the mobile phone according to the present embodiment.
Referring to FIG. 2, a mobile phone 1 includes a control unit 21 for controlling the entire mobile phone 1, a radio circuit 22 connected to an antenna 22A, a codec unit 28 for processing audio data, A switching unit 29 for switching input / output of the codec unit 28; a microphone 13, a first speaker 11, a second speaker 12, a microphone terminal 16 and an earphone terminal 17, which are connected to the switching unit 29; a camera 24; Controls the display of the global positioning system (GPS) 23 for measuring the position of the mobile phone 1, the operation keys 14 for accepting input of user operations, the attitude detection switch 19, the vibration unit 26, and the LCD 16. Display control unit 30 and a ROM (Read Only Memory) for storing a program to be executed by the control unit 21 ) Containing 31, a RAM (Random Access Memory) 32 used as a work area of the control unit 21, address book data, and EEPROM (Electronically Erasable and Programmable ROM) 33 in a non-volatile storage of e-mail or the like.

  The posture detection switch 19 detects a relative position between the operation side unit 3 and the display side unit 2 and outputs it to the control unit. Based on the output of the posture detection switch 19, the control unit 21 detects whether the posture of the mobile phone 1 is in the closed style or the open style.

  The radio circuit 22 receives the radio signal received by the antenna 22 </ b> A and outputs an audio signal obtained by demodulating the radio signal to the codec unit 28. The radio circuit 22 receives the audio signal from the codec unit 28 and outputs a radio signal obtained by modulating the audio signal to the antenna 22A. The codec unit 28 decodes the audio signal input from the radio circuit 22, converts the decoded digital audio signal to analog, amplifies it, and outputs it to the switching unit 29.

  The codec unit 28 receives an analog audio signal from the microphone 13 or the microphone terminal 16 via the switching unit 29, converts the audio signal to digital, encodes it, and sends the encoded audio signal to the radio circuit 22. Output.

  The switching unit 29 is controlled by the control unit 21 and switches input / output of audio signals to the codec unit 28. The switching unit 29 outputs the audio signal received from the codec unit 28 to any one of the earphone terminal 17, the first speaker 11, and the second speaker 12.

  When the earphone is connected to the earphone terminal 17, the audio signal received from the codec unit 28 is output to the earphone terminal 17. When the earphone is not connected to the earphone terminal 17, if the mobile phone 1 is in the hands-free mode, the audio signal received from the codec unit 28 is output to the second speaker 12, and the mobile phone 1 is not in the hands-free mode. The audio signal received from the codec unit 28 is output to the first speaker 11.

  When the user operates the operation key 14, the mobile phone 1 is set to the hands-free mode. Further, even when the mobile phone 1 is in the open style and is not in the hands-free mode, when the mobile phone 1 changes to the closed style, the control unit 21 sets the hands-free mode.

  For this reason, the switching unit 29 outputs the audio signal received from the codec unit 28 to the first speaker 11 if the mobile phone 1 is not set to the hands-free mode when the mobile phone 1 is in an open style and is in a talking state. When the state changes to the closed style, the audio signal received from the codec unit 28 is output to the second speaker 12.

  The switching unit 29 outputs an audio signal output from either the microphone 13 or the microphone terminal 16 to the codec unit 28. The switching unit 29 outputs the audio signal received from the microphone terminal 16 to the codec unit 28 when the microphone is connected to the microphone terminal 16, and from the microphone 13 when the microphone is not connected to the microphone terminal 16. The received audio signal is output to the codec unit 28.

  The display control unit 30 is controlled by the control unit 21 and controls the LCD 15 according to an instruction input from the control unit 21 to display an image on the LCD 15. The image displayed on the LCD 15 includes a moving image and a still image.

A removable flash memory 27A is attached to the card I / F 27. The control unit 21 can access the flash memory 27A via the card I / F 27. Although an example in which a program to be executed by the control unit 21 is stored in the ROM 31 will be described here, the program is stored in the flash memory 27A, the program is read from the flash memory 27A, and the control unit 21 You may make it perform. The recording medium for storing the program is not limited to the flash memory 27A, but is a flexible disk, a cassette tape, an optical disk (CD-ROM (Compact Disc-ROM) / MO (Magnetic Optical Disc) / MD (Mini Disc) / DVD (Digital). Versatile Disc)), an IC card, an optical card, a semiconductor memory such as a mask ROM, EPROM, or EEPROM. Alternatively, the mobile phone 1 may be connected to the Internet via the wireless circuit 22 and a program may be downloaded from a computer connected to the Internet and executed by the control unit 21.
The program here includes not only a program directly executable by the control unit 21 but also a source program, a compressed program, an encrypted program, and the like.

  The camera 24 includes a lens and a photoelectric conversion element such as a CMOS (Complementary Metal Oxide Semiconductor) sensor, and focuses light collected by the lens on the CMOS sensor. The CMOS sensor photoelectrically converts the received light to convert image data. Output to the control unit 21.

  The camera 24 is controlled by the control unit 21, starts imaging in response to an instruction from the control unit 21, and outputs the obtained still image data or moving image data to the control unit 21. The camera 24 includes an image processing circuit that executes image processing for improving the image quality of image data, and an A / D conversion circuit that converts image data from analog to digital. The control unit 21 outputs still image data or moving image data output from the camera 24 to the display control unit 30 and displays it on the LCD 16 or encodes the still image data or moving image data using a compression encoding method, The data is stored in the flash memory 27A attached to the card I / F 27. The camera 24 images the user of the mobile phone 1 when the mobile phone 1 functions as a video phone.

  The EEPROM 33 stores at least a password and a telephone number for setting a lock mode. The password and the telephone number for setting the lock mode are stored in the EEPROM 33 when the user operates the operation unit 14 and inputs them in advance. At least one telephone number for setting the lock mode is stored, and a plurality of telephone numbers may be stored. The EEPROM 33 may store telephone directory data, e-mail data, and an image captured by the camera 24.

  Control unit 21 includes a mode switching unit 51. The mode switching unit 51 switches the mobile phone 1 to either the normal mode or the lock mode. When the lock mode instruction is input, the mode switching unit 51 switches the mobile phone 1 from the normal mode to the lock mode, and sets the mobile phone 1 to the lock mode. When the user presses a predetermined key among the operation keys 14, the control unit 21 receives an input of a lock mode instruction.

  Further, when the radio circuit 22 detects a predetermined number of calls from a telephone assigned with a lock mode setting telephone number within a predetermined time, the control unit 21 inputs a lock mode instruction. Accept. The number of calls, the time for detecting a predetermined number of calls, and the number of calls for a predetermined number of calls can be preset by the user and stored in the EEPROM 33.

  While the mobile phone 1 is set to the lock mode, the control unit 21 inputs an operation instruction from the operation key 14 except when a response key for responding to an incoming call is pressed among the operation keys 14. Even if accepted, the processing corresponding to the operation instruction is not executed.

  For example, even if an operation instruction corresponding to a process for browsing telephone book data or e-mail data is input from the operation key 14, a screen for requesting input of a password without reading the telephone book data or e-mail data from the EEPROM 33. Is displayed on the LCD 15.

  Further, even if a telephone number for calling is input, a screen requesting input of a password is displayed on the LCD 15 without accepting input of the telephone number.

When the control unit 21 switches to the lock mode and the mobile phone 1 is set to the lock mode, when the cancel operation is accepted, the control unit 21 cancels the lock mode and switches to the normal mode.
The canceling operation is an operation in which the user inputs a password stored in advance in the EEPROM 33 to the operation key 14.

  When the password is input while the screen for requesting the password is displayed on the LCD 15, the control unit 21 accepts the release operation, releases the lock mode, and switches to the normal mode.

Although an example in which the password is authenticated and the lock mode is released will be described here, authentication may be performed using biometric information instead of the password.
The biometric information can be a fingerprint, a voiceprint, an iris, a vein pattern, or the like.

  FIG. 3 is a flowchart illustrating an example of the flow of the lock mode process. The lock mode process is a process executed by the control unit 21 when the control unit 21 executes a lock mode processing program. Referring to FIG. 3, control unit 21 determines whether a lock mode instruction has been received (step S01).

  The process waits until a lock mode instruction is accepted (NO in step S01). If a lock mode instruction is accepted, the process proceeds to step S02. That is, the lock mode process is a process executed on condition that a lock mode instruction is received.

  In step S02, the mode of the mobile phone 1 is switched from the normal mode to the lock mode, and the mobile phone 1 is set to the lock mode (step S02).

  In step S03, it is determined whether an incoming call is detected (step S03). If an incoming call is detected, the process proceeds to step S04; otherwise, the process proceeds to step S08. In step S04, it is determined whether or not the incoming call is from a telephone assigned with a lock mode setting telephone number.

  More specifically, it is determined whether or not the telephone number received together with the detected incoming call is stored in the EEPROM 22 as a lock mode setting telephone number. If the incoming call is from a telephone assigned with a lock mode setting telephone number, the process proceeds to step S05; otherwise, the process proceeds to step S10.

In step S10, an incoming call is notified to notify the user that an incoming call has been received. The incoming call notification outputs a ringtone from the second speaker 12. Moreover, you may make it vibrate the vibration part 26. FIG. You may make it vibrate the vibration part 26 while outputting a ringtone.
In step S11, it is determined whether a response instruction has been accepted.

  If it is detected that the user depresses the call button of operation key 14, the process proceeds to step S12. If not detected, the process proceeds to step S14. In step S12, the line is connected in response to the incoming call. As a result, the mobile phone 1 becomes ready for a call. When responding to the incoming call, the incoming call notification started in step S10 is terminated.

  As described above, if the incoming call is not received from the telephone assigned with the lock mode setting telephone number, the incoming call is notified and the user presses the call button so that the line is connected and the mobile telephone 1 can make a call. It becomes a state. In step S13, it is determined whether an instruction to end the call has been accepted.

  If the user detects an operation of pressing the call end button of the operation key 14, the process returns to step S03, and if not detected, the process enters a standby state and the call is continued. On the other hand, in step S14, it is determined whether or not the incoming call is finished. If the incoming call is finished, the process returns to step S03, and if the incoming call is not finished, the process returns to step S10.

  In step S05, the incoming call is automatically answered. As a result, a line is connected to the telephone set to which the telephone number for setting the lock mode is assigned, and a telephone conversation is possible. When the process proceeds to step S05, no incoming call notification is given. For this reason, the user who has the mobile phone 1 does not notice the incoming call.

  In step S06, remote operation processing is executed. The remote operation process will be described later. When the remote operation process ends, the line is disconnected (step S07), and the process proceeds to step S08. In step S08, it is determined whether a lock mode release operation has been accepted. If a release operation is accepted, the process proceeds to step S09; otherwise, the process returns to step S03. In step S09, the mode of the mobile phone 1 is switched from the lock mode to the normal mode, and the mobile phone 1 is set to the normal mode.

  FIG. 4 is a flowchart illustrating an example of the flow of remote operation processing. The remote operation process is a process executed by the control unit 21 in step S06 shown in FIG. The control unit 21 determines whether or not an erasure instruction has been received (step S21).

  If an erasure instruction is received, the process proceeds to step S22. If no erasure instruction is received, the process proceeds to step S23. The erasure instruction is a command for causing the control unit 21 to execute processing for erasing data stored in the EEPROM 33, here, telephone directory data.

  Here, a case where the phone book data is deleted will be described as an example, but e-mail data or image data captured by a camera may be deleted. The erasure instruction is received as a tone signal, for example.

An erase instruction is associated with the tone signal in advance, and when a tone signal corresponding to the erase instruction is received, the telephone directory data is erased from the EEPROM 33 according to the erase instruction.
As a result, even if the cellular phone 1 is released from the lock mode, the phone book data is not browsed because the phone book data is erased.

  The control unit 21 outputs voice guidance for inputting the erasure instruction from the radio circuit 22 in order to make it easier for the user of the telephone set assigned with the lock mode setting telephone number to input the erasure instruction. As a result, the user of the telephone set to which the telephone number for setting the lock mode is assigned simply performs a simple operation of pressing the dial button of the telephone in accordance with the voice guidance, and an erasure instruction is transmitted to the mobile phone 1.

  In step S23, it is determined whether a sound generation instruction has been received. If a sound generation instruction is received, the process proceeds to step S24. If a sound generation instruction is not received, the process proceeds to step S25.

The sound generation instruction is a command for causing the control unit 21 to execute a process of outputting a predetermined sound from the second speaker 12. The predetermined sound is, for example, a ring tone.
In step S24, the second speaker 12 is caused to generate sound.
The control unit 21 causes the second speaker to output a sound even when the mobile phone 1 is set to a silent mode that does not output a ringtone that is output in response to an incoming call.

  Thus, when the user cannot know the location of the mobile phone 1, the user can find the mobile phone 1 if the mobile phone 1 is near the mobile phone 1 by generating a sound.

  The sound output instruction is received as a tone signal in the same manner as the erasure instruction, and the user can easily input the sound output instruction by outputting voice guidance.

  In step S25, it is determined whether a position information transmission instruction has been received. If a position information transmission instruction is received, the process proceeds to step S26. If a position information transmission instruction is not received, the process proceeds to step S28. The position information transmission instruction is a command for causing the control unit 21 to execute processing for transmitting the current position of the mobile phone 1.

  The control unit 21 causes the GPS 23 to measure position information (step S26), and transmits the measured position information to a transmission destination stored in advance in the EEPROM 33 (step S27). The transmission destination may be a telephone network operator's computer or an e-mail address.

  Accordingly, when the user cannot know the location of the mobile phone 1, the user can know the location of the mobile phone 1 by causing the mobile phone 1 to transmit position information.

  The position information transmission instruction is received as a tone signal in the same manner as the erasure instruction, and the user can easily input a sound output instruction by outputting voice guidance.

  In step S28, it is determined whether an unusable setting instruction has been received. If an unusable setting instruction is received, the process proceeds to step S29. If an unusable setting instruction is not received, the process proceeds to step S30. The unusable setting instruction is a command for causing the control unit 21 to execute processing for setting the mobile phone 1 to an unusable state.

When the control unit 21 receives the unusable setting instruction, the control unit 21 sets the mobile phone 1 to an unusable state (step S30). For example, the flag may be stored in the EEPROM 33, and if the flag is stored, the control unit 21 may not be turned on.
When an operation to turn on the power is input, the control unit 21 determines whether or not a flag is stored in the EEPROM 33, and if the flag is stored, the power is not turned on.

  This flag may be rewritten only from an external device connected to the mobile phone 1 once it is rewritten by the control unit 21. Since the mobile phone 1 is set in an unusable state, the data stored in the EEPROM 33 is not viewed by others.

  In addition, since an operation for making an arbitrary call to another telephone is not accepted, a communication fee is not charged.

  In step S30, it is determined whether a destruction instruction has been received. If a destruction instruction is received, the process proceeds to step S31. If a destruction instruction is not received, the process ends. The destruction instruction is a command for causing the control unit 21 to execute processing for destroying the mobile phone 1. When receiving the destruction instruction, the control unit 21 destroys the mobile phone 1 (step S31).

  For example, the control unit 21 destroys the mobile phone 1 by short-circuiting a part of the circuit of the mobile phone 1. Since the cellular phone 1 is destroyed, the data stored in the EEPROM 33 is not viewed by others. In addition, since an operation for making an arbitrary call to another telephone is not accepted, a communication fee is not charged.

  FIG. 5 is a flowchart showing an exemplary flow of a call end operation acceptance process. The call end operation acceptance process is a process executed by the control unit 21 when the mobile phone 1 is in a call-capable state with a line connected to another phone.

  The control unit 21 determines whether a call end operation has been accepted (step S41). The process waits until a call end operation is accepted (NO in step S41). If a call end operation is accepted, the process proceeds to step S42.

  When the user presses a predetermined key corresponding to the operation for ending the call among the operation keys 14, the control unit 21 receives the call end operation.

  In step S42, it is determined whether or not the mobile phone 1 is set to the lock mode. If the lock mode is set, the process proceeds to step S43. If the lock mode is set to the normal mode, the process proceeds to step S44.

  In step S43, the process is on standby until the other party's telephone disconnects the line (NO in step S43). If the other party's telephone disconnects the line, the process ends. On the other hand, in step S44, the line is disconnected and the process ends.

  As described above, when the mobile phone 1 is set to the lock mode, the line is not disconnected even if the user performs a call end operation. For this reason, when the line is connected to the telephone set to which the telephone number for setting the lock mode is assigned when the lock mode is set, the mobile phone 1 does not disconnect the line. For this reason, since the line is connected unless the telephone to which the telephone number for setting the lock mode is assigned disconnects the line, the user surely causes the mobile phone 1 to execute the remote operation processing by remote operation. Can do.

  FIG. 6 is a flowchart illustrating an example of the flow of power-off operation reception processing. The power-off operation acceptance process is a process executed by the control unit 21 when the mobile phone 1 is in a power-on state. The control unit 21 determines whether or not a power-off operation has been received (step S51).

  The process waits until a power-off operation is accepted (NO in step S51). If a power-off operation is accepted, the process proceeds to step S52. When the user presses the power key A of the operation key 14, the control unit 21 receives a power off operation.

  In step S52, it is determined whether or not the mobile phone 1 is set to the lock mode. If the lock mode is set, the process proceeds to step S53. If the lock mode is set to the normal mode, the process proceeds to step S54. In step S53, it is determined whether or not the execution of the remote operation process is completed. The process waits until the execution of the remote operation process is completed (NO in step S53). When the execution of the remote operation process is completed, the process proceeds to step S54.

  When the remote operation process shown in step S06 in FIG. 3 is completed, the control unit 21 stores history information indicating that the remote operation process has been executed in the EEPROM 33, and switches to the normal mode in step S09 in FIG. At this time, the history information stored in the EEPROM 33 is erased.

  In step S53, the history information is read from the EEPROM 33, and it is determined whether or not the remote operation process has been executed.

  If no history information is stored, the process enters a standby state. When the history information is stored in the EEPROM 33, the process proceeds to step S54. In step S54, the power is turned off and the process is terminated.

  In this way, even if a power-off operation is accepted while the mobile phone 1 is set to the lock mode, if the remote operation process has not been executed and the process has not been completed, the power is not turned off. The power is kept on. For this reason, after the mobile phone 1 is set to the lock mode, the mobile phone 1 can execute the remote operation process at least once.

  Note that the number of times the remote operation process has been executed is stored in the EEPROM 33 as history information so that the power is not turned off even if a power-off operation is accepted until a predetermined number of times of remote operation process is executed. good.
