JPH1023530A - Mobile terminal equipment - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a terminal equipment from being used by another party even when a key is missed by locking dial automatically when no key input is inputted with in a prescribed time even when dial lock release is left unlocked or the key is missed. SOLUTION: When dial lock is locked, a key input of an input section 14 sets a dial lock setting state. Then the dial lock setting is activated by key input and a password being a dial lock number is inputted to a rewritable read only memory EP-ROM. Furthermore, when an automatic lock timer value of a prescribed time is set by key entry, dial lock is locked. When the setting is activated and a dial lock number is inputted, a new password is set to change the automatic lock timer value. If the dial lock release is left unlocked or the terminal equipment is missed, the dial lock is automatically locked when no key input is received for a prescribed time. Thus, even when the terminal equipment is missed, the terminal equipment is not used by other party.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile terminal having a function of locking a dial to prevent use by others.

[0002]

2. Description of the Related Art Conventionally, in order to prevent a mobile terminal from being used by another person by applying a dial lock, a transition is made to a dial lock setting state by a key input with a function key or the like, and a key input with a specific key or the like is performed there. Enter the dial lock number (PIN) or turn on the dial lock setting state to apply the dial lock. When the dial lock is released, the state is shifted to the dial lock release state by key input with a function key or the like. When the dial lock release number (password) is input by key input and the password matches, the dial lock is released. Unlock it so that others can use it. If you want to lock the dial again, you can enter the key lock to enter the dial lock setting state.If you enter the dial lock number, this number becomes the latest security code and the dial lock is applied. , Locked with the previous PIN. Conventionally, when the dial lock is released, the lock is not performed unless the dial lock is applied again.

[0003]

As described above, in the conventional example, there is a problem that after unlocking the dial, if the lock is forgotten or lost, it is used by another person.

[0004]

SUMMARY OF THE INVENTION The terminal of the present invention is intended to solve the above-mentioned problem of the prior art in that the dial lock is released and the lock is used by another person when the lock is forgotten or lost. If there is no key input for a certain period of time after releasing the dial lock as shown in FIG.
It has a function to automatically lock the dial.

[0005]

FIG. 1 is a block diagram showing an example of a mobile terminal to which the present invention is applied. In FIG. 1, 1
9 is an antenna, 18 is a high-frequency circuit that amplifies transmission and reception signals, 11 is a control unit that performs switching between transmission and reception, and 12 is a speaker that connects electric signals to audio and audio to electric signals.
3 is a display unit, 14 is a key input unit, 15 is a push dial, 16 is a memory, and 17 is a rewritable read-only memory EP-ROM.

[0006] In such a mobile terminal, when the dial lock is to be applied, as shown in FIG.
When the key is pressed, the state shifts to the dial lock setting state, where the dial lock setting is turned on by key input, a dial lock number (password) is input, and a certain period of time is set by key input, that is, an auto lock timer value is set. Then, the dial lock is activated. Also, if the dial lock number is entered while the setting is on, the password becomes a new password,
The auto lock timer value can be changed. When the dial lock is released, the dial lock is released by key input, and the dial lock release number (personal identification number) is input with the key to release the dial lock.

If the user forgets or loses the dial lock while unlocking it, there is a risk that the dial lock will be used by others. However, according to the present invention, if there is no key input for a certain time after the dial lock is unlocked, If you forget or lose the lock while the dial lock is released, the dial lock will be performed automatically after a certain period of time. That is, when the dial lock is released as shown in FIG. 2 (B), the auto lock timer value is set, and the auto lock timer is started. It will not be used by others. For example, it is impossible to make a call by push dial or memory dial, call memory dial, register, and the like.

[0008]

As described above, according to the present invention, even if the user forgets or loses the dial lock in the unlocked state, it is not used by others. Further, the dial lock setting can be performed without operating the keys in the dial lock released state.
