Description

  The present invention relates to a mobile terminal.

  In general, mobile terminals such as mobile phones, PHS, and PDAs are important data for the owner, such as data specifying the owner, relatives, friends, etc. such as address, telephone number, date of birth, etc. A lot of data etc. are recorded. In addition, in the case of a mobile terminal having a mobile communication function such as a mobile phone or a PHS, it is possible to make and receive calls at any location as long as radio waves can reach from the base station.

  However, since the mobile terminal is carried by the owner when going out, there is a high possibility that the mobile terminal will be misplaced or stolen while going out. There was a problem that some important data was stolen or called without permission.

  Further, in order to partially solve these problems, a device that requires the user to input a password when the portable terminal is turned on has been put into practical use to confirm that the user is the owner.

  However, with this password method, it is necessary to input a password every time the mobile terminal is turned on, which is not practical for owners who frequently use the mobile terminal on a daily basis. In addition, if the device is misplaced or stolen while the power is on, it could not be prevented from being used inappropriately.

  In addition, there has been proposed a method for confirming an owner by pressing a power-on key and a predetermined key multiple times when the mobile terminal is turned on.

(See Patent Document 1).
JP 2000-197141 A

  However, this multi-push method has the advantage that the method of checking the owner when the mobile terminal is turned on is relatively simple. However, as with the password method described above, it can be left with the power turned on. If it is stolen, it cannot be prevented from being used improperly.

  Therefore, there is a need for a portable terminal that does not require a complicated confirmation operation from the owner and can prevent unauthorized use even if the owner is left misplaced or stolen while the power is on.

  The portable terminal of the present invention has a first mode in which a plurality of functions can be respectively executed and a second mode in which execution of a specific function among the plurality of functions is restricted, and according to an instruction operation by an operator A mobile terminal capable of executing each of a plurality of functions, the detection means for detecting the instruction operation, the setting means for setting an arbitrary function from the plurality of functions as a predetermined function, and the detection means, And a mode setting means for setting to the second mode when an instruction operation for executing the predetermined function among a plurality of functions is detected.

  Preferably, the mode setting means switches to the first mode when detecting that a correct password is input by the password function for detecting input of a password in the second mode. .

  Preferably, the specific function is the telephone call function.

  Preferably, a predetermined notification is given when the mode is switched to the second mode.

  According to the portable terminal of the present invention, there is an effect that it is possible to prevent unfair use even when the owner is not required to perform a complicated confirmation operation and is left misplaced or stolen while the power is turned on.

The present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of an embodiment of the present invention, where 1 is an antenna, 2 is a radio unit, 3 is a control unit, and 4 is a storage unit. Reference numeral 5 denotes a display unit, 6 denotes an operation unit (detection means), 8 denotes an audio processing unit, and the control unit 3 stores the radio unit 2, the audio processing unit 8, the display unit 5, and the operation unit 6 in the storage unit 4. Control is performed based on stored control software and application software.

  A microphone 9 and a speaker 10 are connected to the voice processing unit 8, and a voice call can be made via a communication line in cooperation with the antenna 1 and the radio unit 2 described above.

  In addition to the control software and application software, the storage unit 4 stores address book data, telephone number book data, memo data, schedule data, personal data, and the like input by operating the operation unit 6. .

  Reference numeral 11 denotes an alarm unit for outputting an alarm sound in order to notify when it is detected that the mobile terminal 7 is being used by a third party.

  Further, the portable terminal 7 stores the address book data, telephone number book data, memo data, schedule data, and personal data stored in the storage unit 4 by application software stored in the storage unit 4. Used address book display function, telephone number display function, registered data search function, calendar function, memo function, schedule function, various setting functions, music playback function, image data display function, telephone call function, telephone call function, mail function A plurality of functions such as an Internet search function can be executed.

  FIG. 2 is a flowchart showing a first operation according to the embodiment of the present invention.

  When the mobile terminal 7 is turned on, first, the first mode is set in step S100. The first mode means a mode on the premise that the owner uses a portable terminal. For example, a state where a plurality of functions as described above can be executed, or only a part of the functions is protected by a password method. In the case where the portable terminal has a function to be performed, it means that the function that is not protected by the password can be executed.

  In step S101, it is detected whether or not the operation key of the operation unit 6 has been operated.

  If no key operation is detected, the detection in step S101 is repeated, and if a key operation is detected, the process proceeds to step S102.

  In step S102, it is detected whether or not the previous key operation selects a predetermined function from a plurality of functions of the portable terminal 7 and instructs execution thereof.

  The predetermined function is preferably a function that the owner does not need to execute frequently or a function that does not need to be executed at all, such as a display of the phone number of the mobile terminal 7 (the owner of the mobile terminal 7). Since the owner does not need to execute the telephone number display function provided in the portable terminal 7 by storing his / her own telephone number), it is determined in advance when the portable terminal 7 is shipped from the factory. Alternatively, the owner may be able to set the operation unit 6 in advance. Further, this setting means may be protected by a password input so as not to be freely set as a predetermined function by operating the operation unit 6 of a third party. Further, one function may be set, and setting of an arbitrary number of functions is also included.

  If the predetermined function is not selected as the function to be executed in step S102, the process proceeds to step S103, where the actually selected function such as a memo function is executed, and the process returns to step S101.

  If the predetermined function is selected as the function to be executed in step S102, the process proceeds to step S104, and execution of the telephone number display of the actually selected mobile terminal 7, for example, is prohibited. Then, the process proceeds to step S105 to automatically shift to the second mode.

  The second mode in step S105 is based on the premise that the mobile terminal 7 is used by a third party who is not the owner, and in other words, means a mode in which the mobile terminal 7 may be used illegally. That is, the second mode is a mode premised on the use of the mobile terminal by a third party other than the owner, and means a mode different from the first mode described above. Note that the second mode includes restricting execution of a specific function of the mobile terminal, restricting all functions, and notifying that an operation has been performed by a third party.

  This specific function is a function that is frequently executed by the owner, and is a function that displays data that a third party does not want to be known or a telephone that is charged, for example, an individual of the mobile terminal 7 A data display function, a telephone directory display function, an address book display function, a telephone call function, and an Internet search function, etc., which may be predetermined at the time of factory shipment of the mobile terminal 7, The owner may be able to set by operating the operation unit 6 in advance.

  Further, the specific function may be one of a plurality of functions provided in the mobile terminal 7, or a combination of a plurality of functions such as a telephone directory display function and a telephone call function. To do.

  Subsequent to step S105, a notification operation in step S106 is performed. The notification operation in step S106 is a subroutine, and the actual notification operation is notified by a flowchart shown in FIG. 3 to be described later.

  When the notification operation in step S106 described later is completed, the process proceeds to step S107, and it is detected whether or not the operation key of the operation unit 6 has been operated.

  If no key operation is detected, the detection in step S107 is repeated, and if a key operation is detected, the process proceeds to step S108.

  In step S108, it is detected whether the previous key operation selects a specific function from a plurality of functions of the portable terminal 7 and instructs execution.

  When a specific function is selected as a function to be executed in step S108 (here, for example, a call transmission function is selected), the process proceeds to step S109, and the execution of the selected function is prohibited. The operation returns to step S107.

  On the other hand, as a function other than the specific function in step S108, for example, there is no possibility of seeing confidential data or the like even if executed by a third party such as a memo pad function or a risk of paying a telephone charge. If a function is selected, the process proceeds to step S111.

  In step S111, the selected function is executed, and the process returns to step S107.

  Further, if no function is selected in step S110, the process proceeds to step S112. In step S112, it is detected whether or not the key operation detected in step S107 is a password input.

  If it is detected in step S112 that the password has been correctly input, the process proceeds to the subsequent step S113 to automatically return to the first mode and return to the process in step S101.

  If it is detected in step S112 that the key operation is not a correct password input, the process returns to step S107 while maintaining the second mode, and processing for waiting for an operation key input is performed.

  Next, the notification operation in step S106 will be described based on FIG.

  When the notification operation is executed in step S106, the process proceeds to step S200, the owner's telephone number is searched from personal data or address book data stored in the storage unit 4 of the portable terminal 7, and the telephone number is transmitted. To do.

  In step S201, it is detected whether or not the previous call is actually received, and the operation of repeating step S201 is performed until the call is received.

  If it is detected in step S201 that an incoming call has been made, the process proceeds to step S202, and a voice synthesizing unit (not shown in FIG. 1) informs by voice that the mobile terminal 7 is being used by a third party. (Predetermined notification) and alert the owner.

  Furthermore, it progresses to step S203 and searches the telephone number of the communication enterprise which the owner subscribes and has registered the portable terminal 7 from the memory | storage part 4, and transmits to the telephone number.

  In subsequent step S204, processing similar to that in step S201 is performed. When an incoming call is actually made, the process proceeds to step S205.

  In step S205, the telecommunications carrier is informed that there is a possibility that it is illegally used by a third party by speech synthesis in the same manner as in step S202, and the restriction of outgoing and incoming calls of the mobile terminal 7 by the telecommunications carrier. Prompt.

  In the subsequent step S206, the alarm unit 11 shown in FIG. 1 reports a beep sound for a predetermined time (performs a predetermined notification) and gives a warning to a third party.

  When this step S206 is executed, the process proceeds to step S107 in FIG. 2, and the subsequent processing is executed.

  Further, the notification operation of the present invention is the above-described voice telephone notification, but the present invention is not limited to this, and may be notified by e-mail transmission, for example.

  As described above, it is possible to prevent unfair use without requiring a complicated confirmation operation from the owner as compared with a conventional method in which a password must be input every time the power is turned on or an operation is performed.

  In addition, when the mobile terminal 7 is lost after entering the password, the conventional mobile terminal cannot prevent unauthorized use by a third party. Even so, it is possible to effectively prevent the use of a third party.

  In addition, since the owner can set and register functions that are not desired to be executed by a third party in advance, unauthorized use by a third party can be prevented more flexibly.

  In addition, even if the owner does not require complicated confirmation operations and the device is misplaced or stolen while the power is turned on, unauthorized use by other people can be suppressed, or the owner or carrier can be informed. You can do it.

  Furthermore, if the owner remembers the phone number of his / her mobile terminal, he / she does not need to execute the phone number display function of his / her mobile terminal, and when misusing the mobile terminal acquired by a third party, Paying attention to the prediction that the third party will first look up the phone number of the mobile terminal that will be needed first, and if the predetermined function is set as the display of the phone number of the mobile terminal, the owner will Depending on the operation of the phone number display function of the mobile terminal that the owner does not operate first, even if it is misplaced or stolen with the power on, while complicated confirmation operations are unnecessary Since an operation by a third party is detected, it is possible to provide a mobile terminal that can detect with higher accuracy and can more reliably prevent unauthorized use.

  Further, in this embodiment, when the specific function described above is a telephone call function, even if the execution of the telephone call function is selected in the second mode, the execution is restricted, which is complicated for the owner. Even when a confirmation operation is not requested and the user is left misplaced or stolen while the power is turned on, it is possible to suitably prevent a telephone call by another person.

  Next, another embodiment of the present invention will be described based on an external view of the mobile terminal 7 in FIG. 4 and a flowchart of the second operation in FIG.

  FIG. 4 shows an example of the appearance of the mobile terminal 7, and the same reference numerals as those in FIG. In FIG. 4, reference numeral 12 denotes a cross direction key, which is used for selecting a menu displayed on the display unit 5. Reference numeral 13 denotes a menu key. When this menu key is operated when the display unit 5 is in the standby screen, the standby screen immediately switches to the menu selection screen.

  In the example of the present invention, after the display on the display unit 5 is switched to the menu screen by the operation of the menu key, the operation is performed four times in the downward direction of the cross direction key 12 (displayed by the up and down operation of the cross direction key). The various functions that can be selected with the enter key, which will be described later, displayed on the unit 5 are scrolled), and the enter key arranged in the middle of the cross direction key 12 is operated as the function for executing the telephone number display function. Shall.

  Arranged substantially below the cross direction key 12 are various operation keys including a numeric keypad, and these keys collectively correspond to the operation unit 6.

  In the portable terminal 7 shown in FIG. 4, when the left direction of the cross direction key 12 is operated while the display unit 5 is in the standby screen state, the screen is switched to the shortcut key operation screen. When an operation using the numeric keypad is performed after the operation, a telephone number display function and other functions are selected and executed in accordance with an operation of “0” to “9” or “*” and “#” of the numeric keypad.

  In the example of the present invention, it is assumed that the telephone number display function is automatically selected by the operation of the “0” key of the numeric keypad after the left operation of the cross direction key 12.

  In FIG. 5, when the power is turned on, first, the first mode is set in step S300. The first mode means a mode that assumes use of the portable terminal by the owner.

  In step S301, it is detected whether the operation key of the operation unit 6 has been operated.

  If no key operation is detected, the detection in step S301 is repeated, and if a key operation is detected, the process proceeds to step S302.

  In step S302, the left key operation of the cross direction key 12 and the ten-key “0” which are the above-described shortened key operation (second combination instruction operation) among the plurality of functions of the portable terminal 7 as the previous key operation. It is detected whether or not the phone number display function is selected by operating the "" key and the execution is instructed.

  In step S302, when the telephone number display function is selected as a function to be executed by the shortcut key operation, the process proceeds to step S303, the telephone number display function is actually executed, and the process returns to step S301 to repeat the process.

  If it is determined in step S302 that the instruction operation (first combination instruction operation) is not an instruction operation of the telephone number display function by a shortened key operation, the process proceeds to step 304, and the telephone is selected by a menu selection operation in step S304. It is detected whether the number display function is selected and execution is instructed.

  If it is determined that the instruction is not an instruction to execute the telephone number display function by the menu selection operation, the process proceeds to step S305, and the function actually selected for execution, such as the memo function, is executed, and step S301 is executed. Return to and processing will continue.

  If it is determined in step S304 that the instruction is to execute the telephone number display function by the menu selection operation, the process proceeds to step S306, where it is detected that the operation is performed by a third party, and the third party The mode automatically shifts to the second mode that may be used illegally.

  Here, abbreviated key operations can generally be used only after familiarizing with the operation method of the mobile terminal 7, and are first used in the case of mobile terminals that the user owns daily and does not use frequently. Presumed not to be possible.

  For owners who are familiar with the operation method, it is easier to select a function by operating the abbreviated key, so it is common not to perform a selection operation from a menu screen that is bothersome and troublesome. It is also.

  Furthermore, when the portable terminal 7 is illegally acquired by a third party who does not know the operation method, it is presumed that the shortcut key operation is not performed first, and various functions are selected from the menu screen and attempted to be executed. .

  Therefore, in view of the above points, the present invention determines that the owner is performing an instruction operation when a shortened key operation is performed, while the instruction operation for selecting a function from the menu screen is performed. It is determined that a third party is operating.

  After the process in step S307, the notification operation in step S308 is performed. This step S308 is a subroutine similar to the notification operation of step S106 in the flowchart of FIG. 2 described above, and the actual notification operation is notified according to the flowchart shown in FIG.

  When the notification operation in step S308 ends, the process proceeds to step S309, and it is detected whether or not the operation key of the operation unit 6 has been operated.

  If no key operation is detected, the detection in step S309 is repeated, and if a key operation is detected, the process proceeds to step S310.

In step S310, whether the previous key operation is a specific function that is not desired to be executed by a third party among a plurality of functions of the mobile terminal 7, for example, is a telephone call function being selected and instructed to be executed. If the telephone call function is selected as the function to be executed in step S310, the process proceeds to step S311 to prohibit the execution of the telephone call function and return to step S309.

  On the other hand, as a function other than the function of making a call in step S310, for example, a function such as a memo pad function that does not have a possibility of seeing confidential data even if executed by a third party, or a possibility of paying a telephone charge. If no function is selected, the process proceeds to step S313, the function is executed, and the process returns to step S309.

  If it is determined in step S312 that execution of the function has not been instructed, the process proceeds to step S314. In step S314, it is detected whether or not the key operation detected in step S309 is a password input.

  If it is detected in step S314 that the password has been correctly input, the process proceeds to the subsequent step S315 to automatically return to the first mode and return to the process in step S301.

  If it is detected in step S314 that the key operation is not a correct password input, the process returns to step S309 while maintaining the second mode, and processing for waiting for an operation key input is performed.

  Further, according to the operation of the flowchart shown in FIG. 5, the function that is not desired to be executed by a third party is only the telephone call. However, the present invention is not limited to this, and the owner has a large number of functions in advance. It may be possible to set and register functions.

  Furthermore, according to the operation of the flowchart shown in FIG. 5, in order to detect the use of a third party, the telephone number display function is adopted as there are two instruction operation methods for selecting the same function. However, the present invention is not limited to this, and any other function having two instruction operation methods can be adopted as appropriate. In addition, not only one function is targeted, but, for example, if the telephone number display function, the address book display function, and the phone book display function each have two instruction operation methods, If the function is selected by other than the shortcut key operation, the mode may be immediately shifted to the second mode.

  Further, in the above example, the example in which the shortcut key operation is designated as the owner's instruction operation is shown. However, when there are two types of instruction operations other than the shortcut key operation, either one of the instruction operations is performed. The instruction operation of the owner may be determined and the other instruction operation may be determined as the instruction operation of the third party.

  As described above, it is possible to prevent unfair use without requiring a complicated confirmation operation from the owner as compared with a conventional method in which a password must be input every time the power is turned on or an operation is performed.

  In addition, when the mobile terminal 7 is lost after entering the password, the conventional mobile terminal cannot prevent unauthorized use by a third party. Even so, it is possible to effectively prevent the use of a third party.

  Although the embodiment of the present invention has been described above, the mobile terminal of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention. Of course.
