First, an example of the control at the time of the theft function operation of the portable telephone constructed as described above will be described with reference to the flowchart shown in FIG.

When the user operates the operation unit 6 to instruct the setting of the personal identification number and inputs the personal identification number in a state where the personal identification number is not registered, the input personal identification number is stored in the data storage part 7. Is done.

When the user operates the operation unit 6 to instruct the activation of the anti-theft function in a state where the personal identification number is registered (step F1), the main control unit 9 issues an instruction signal from the operation unit 6. (For example, a call start / end instruction, a telephone directory display instruction, and the like) are disabled so that some functions are disabled (step F2).
A message prompting the input of a personal identification number is issued (step F3).

Then, in this state, the user operates the operation unit 6 to input a password (step F4).
And the main control unit 9 compares the input personal identification number with the personal identification number stored in the data storage unit 7 (step F).
5) Only when there is a match, all the functions can be used by setting all the instruction signals from the operation unit 6 that have been partially invalidated to be valid (step F6), and the clock unit 8 is turned on. Control is performed to start timing (step F7).

Before the time measured by the clock unit 8 reaches the predetermined time (step F8),
When the user operates the operation unit 6 to instruct the anti-theft function to stop (step F9), the main control unit 9 ends the operation control of the anti-theft function, and the operation unit 6 stops the anti-theft function. Without being instructed (step F9), the clock unit 8
Is determined to have reached the predetermined time (step F8), the main control unit 9 disables some functions (step F10) at a timing when no call is being made (step F10). F2) Thereafter, the same operation control (steps F3 to F10) is repeated.

Therefore, according to the above operation control, all operations can be freely performed only until a predetermined time elapses after the password numbers match.

Next, another example of control at the time of the theft function operation in the portable telephone constructed as described above will be described with reference to the flowchart shown in FIG.

When the user operates the operation unit 6 and instructs activation of the anti-theft function (step F11) in a state where the personal identification number is registered, the main control unit 9 receives one of the instruction signals from the operation unit 6. (For example, a call start / end instruction, a telephone directory display instruction, etc.) by disabling some of the functions (step F12), and issuing a notification urging the input of a personal identification number (step F12).

In this state, when the user operates the operation unit 6 to instruct the anti-theft function to stop (step F18), the main control unit 9 ends the operation control of the anti-theft function and restarts the operation. When the start of a call is instructed based on the operation of the unit 6 and it is detected that a call with the other party has been started (step F17), the main control unit 9 controls the clock unit 8 to control the call. Time T is measured (step F1)
9) After that, when the call with the other party ends (step F20), the call time T measured by the clock unit 8
Is added to the total call time Tn stored in the data storage unit 7 and updated and stored (step F21), and it is determined whether the total call time Tn is longer than the predetermined call time Tx (step F22), and the total call time is determined. Only when it is determined that the time Tn is longer than the predetermined call time Tx, some functions are disabled (step F12), and the same operation control (steps F13 to F22) is repeated thereafter.

Therefore, according to the above-described operation control, all operations can be freely performed only during a period from the coincidence of the personal identification numbers until the total talk time reaches a predetermined time.

Next, still another example of the control at the time of the theft function operation in the portable telephone configured as described above will be described with reference to the flowchart shown in FIG.

When the user operates the operation unit 6 to instruct the activation of the anti-theft function in a state where the personal identification number is registered (step F31), the main control unit 9 receives one of the instruction signals from the operation unit 6. (For example, a call start / end instruction, a telephone directory display instruction, etc.) by disabling some of the functions (step F32) and issuing a notification prompting the input of a personal identification number (step F32). F33).

Then, in this state, the user operates the operation unit 6 to input a password (step F34).
And the main control unit 9 compares the input personal identification number with the personal identification number stored in the data storage unit 7 (step F).
35) Only when they match, all the functions can be used by setting all the instruction signals from the operation unit 6 that have been partially invalidated to be valid (step F36).

In this state, when the user operates the operation unit 6 to instruct the anti-theft function to stop (step F38), the main control unit 9 terminates the operation control of the anti-theft function, and operates again. When a start of a call is instructed based on an operation of the unit 6 and it is detected that a call with the other party has been started (step F37), the main control unit 9 is stored in the data storage unit 7. “1” is added to the number of communications Nn and updated and stored (step F39), and when the communication with the other party is terminated (step F40), it is determined whether the updated and stored number of communications Nn is equal to or more than a predetermined number Nx. Only when it is determined that the number of communications Nn is equal to or greater than the predetermined number of times Nx (step F41), some functions are disabled (step F32), and the same operation control (steps F33 to F33) is performed thereafter. Repeatedly performing the operations of 41).

Therefore, according to the above-described operation control, all operations can be freely performed only from the time when the passwords coincide with each other until the number of subsequent communications reaches the predetermined number.

F53).

Then, in this state, the user operates the operation unit 6 to input a password (step F54).
And the main control unit 9 compares the input personal identification number with the personal identification number stored in the data storage unit 7 (step F).
55) Only when they match, all the functions can be used by setting all the instruction signals from the operation unit 6 that have been partially invalidated to be valid (step F56).

In this state, when the user operates the operation unit 6 to instruct the anti-theft function to stop (step F58), the main control unit 9 terminates the operation control of the anti-theft function and restarts the operation. When the start of a call is instructed based on the operation of the unit 6 and it is detected that the call with the other party has been started (step F57), the main control unit 9 sets the call time and the telephone number of the other party. A call charge K for the call is calculated based on the call charge (step F59). When the call with the other party is terminated (step F60), the call charge K calculated by the main control unit 9 is stored in the data storage unit. 7 is updated and stored in addition to the call charge Kn stored in step 7 (step F61), and the updated and stored call charge K is added.
It is determined whether or not n is equal to or greater than a predetermined charge Kx (step F6).
2) Only when it is determined that the call charge Kn is equal to or higher than the predetermined charge Kx, some functions are disabled (step F).
52), and thereafter, the same operation control (steps F53 to F6)
The operation of 2) is repeated.

Therefore, according to the above-described operation control, all operations can be freely performed only during a period from the coincidence of the personal identification numbers to the subsequent total call charge reaching the predetermined call charge.

In the above-described embodiment, the operation control of the anti-theft function is ended by the stop instruction of the anti-theft function in the operation unit 6 in a state where all the functions can be used. Is not
For example, the user may be prompted to input a personal identification number again before terminating the operation control of the anti-theft function, and the operation control of the anti-theft function may be terminated only when the passwords match each other. Unauthorized use can be more reliably prevented.

In the above-described embodiment, the security code is registered in a state where the security code is not registered. However, the present invention is not limited to this. For example, when the security function is activated, The user may be prompted to input a personal identification number, and may register the input personal identification number. With this configuration, the personal identification number can be easily changed.

Further, even when various functions are disabled when the anti-theft function is activated, only the function of informing the base station of its own position based on a predetermined radio wave from the base station is enabled without being disabled. This makes it possible to easily find a stolen mobile phone.
