Power control method for mobile phone {POWER CONTROL METHOD FOR CELLULAR PHONE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply control method for a mobile phone, and more particularly, to a mobile phone having a function such as an electronic notebook, the power supply of a mobile phone controlling power so that only a function such as an electronic notebook can be used while the mobile phone is turned off. It relates to a control method.

In recent years, mobile phones have developed into a multifunctional device capable of using not only a call function, which is its original purpose, but also a schedule management, a phone book, a calculator, a game, and a wireless Internet. However, the use of the mobile device is limited by the limitation of the power usage time of the portable device. Accordingly, a method for reducing power consumption of the mobile phone has been sought.

FIG. 1 is a circuit diagram of a power supply unit of a conventional cellular phone. As shown in FIG. 1, the power button 1 performs a switching operation to supply power to the battery 2 to the entire cellular phone.

The mobile phone including the power supply unit configured as described above has been developed as a multifunction device with electronic organizer functions such as schedule management, world clock, calculator, phone book, etc. Minimize the power consumption during the call, especially in the basement or outside the calling area, such as in the mobile phone mode by changing the mode of the power consumption of the mobile phone is being used as much as possible.

In such a conventional mobile phone, when using an electronic notebook, phone book, wireless Internet, etc., the user presses the provided power button 1 to supply power to the battery corresponding to the case where the mobile phone mode is normal.

Then, the user selects the menu or function button of the cellular phone to use the electronic organizer function, the phone book function, or to make a call.

As such, additional functions such as an electronic organizer function can be used only while the power supply of the cellular phone is normally supplied. When the power is supplied in an appropriate amount for the mode for reducing power consumption, other additional functions cannot be used.

As described above, since the electronic organizer function cannot be used when the cellular phone is turned off, its use efficiency is lowered, and power consumption is relatively increased, thereby reducing the usable time of the battery.

It is an object of the present invention to provide a method for controlling a power supply of a mobile phone that enables the use of other functions such as an electronic notebook while supplying the power of the mobile phone to a power saving mode state to a minimum.

10: battery 20: substrate

30: constant voltage supply

The above object is the power supply step of supplying power to the mobile phone by mounting a battery; An initial operation step of supplying the power to execute a boot sequence and executing an initial operation in a power saving mode or a normal mode depending on whether a call is available; This is achieved by configuring an operation mode determining step of freely operating the state of the mobile phone in a power saving mode or a normal mode by using a designated button according to a user's selection. The present invention will be described in detail with reference to the accompanying drawings. As follows.

FIG. 2 is a circuit diagram of a power supply unit for applying the present invention, in which only a constant voltage supply unit 30 that maintains a constant voltage between the battery 10 and the cellular phone substrate 20 is provided.

The characteristic of the above configuration is that when the battery 10 is mounted on the cellular phone main body, power is applied to the substrate 20 through the constant voltage supply unit 30 so that the cellular phone can be used.

When the battery 10 is mounted, power is always supplied to the mobile phone. In order to reduce the power consumption, power consumption can be controlled through software processing, that is, mode change.

In other words, in the past, the power is controlled using the power button as a switch, but in the present invention, the role of supplying and shutting off the power is switched to the detachment of the battery, and the hardware is always carried when the battery is installed. Power is being supplied to the phone, and power consumption can be reduced by freely changing between the deep sleep mode and the normal mode according to the user's choice.

Currently, mobile phones are designed to go into deep sleep in order to save power in areas where RF signal is weak. With current technology, the phone is in deep sleep. There is no function to switch to, and this is done automatically only if the RF signal is detected.

In the deep sleep mode, the power consumption of the mobile phone is extremely low, the battery life is increased, and the deep sleep mode is configured to be applied to the user's choice.

3 is a flowchart of a method for controlling a power supply of a mobile phone according to the present invention, and a power supply step of applying a power to a mobile phone by mounting a battery as shown therein; When the power is applied, executes a boot sequence, checks a reception state at a current position, and enters a deep sleep mode, which is a power saving mode when the RF signal is weak, and switches to a normal mode when the RF signal is not weak; ; By operating the power button according to the user's selection consists of a step of freely switching between the power saving mode deep sleep mode and normal mode.

Hereinafter, the power control method of the mobile phone of the present invention as described above will be described in more detail.

First, when the battery is connected to the main body of the cellular phone, power is applied to the cellular phone.

At this time, the power is directly applied without pressing the power button as in the prior art, and the subsequent control of the power is performed through software processing.

Then, by applying the power, the cellular phone executes its own boot sequence, and when the execution is completed, the mobile phone enters the deep sleep mode or the normal mode, which is a power saving mode, depending on the strength of the RF signal.

At this time, when the mobile phone operates in the deep sleep mode, it is impossible to make a call, and it is possible to use an electronic notebook function or a phone book as an additional function. In the normal mode, the call function can be used.

The usage of the additional functions in the normal mode and the deep sleep mode is the same as the usage and procedure, but the use in the deep sleep mode can consume less power.

Then, when the mode of the mobile phone that has executed the boot sequence as described above is a normal mode, if there is no place to call, or there is no call to perform a mode conversion function, a new function of the power button.

In other words, if you do not want to call, by pressing the power button forcibly enters the deep sleep mode of the mobile phone in the region where the RF signal is weak.

At this time, the power button is a function key that can be selectively switched to the deep sleep mode and the normal mode according to the number of times of pressing, which is possible by the conversion of the configuration of the power supply and the software processing according to the power key input.

If the current operation mode of the mobile phone is the normal mode, press the power key to change the operation mode to the deep sleep mode, in this way, in the deep sleep mode, the user can use additional functions such as electronic notebook, phone book.

When the power key is pressed again in the above state, it returns to the normal mode from the forced deep sleep mode, whereby the user can answer or make a call.

In this way, the user can change the mobile phone's status mode arbitrarily by using the power button, forcing the user to switch to the deep sleep mode with low power consumption so that the mobile phone can not be called, i.e., turned off. By setting and using additional functions such as an electronic notebook, power consumption can be further reduced.

As described above, the power control method of the mobile phone according to the present invention enables a software process to forcibly switch the state of the mobile phone to the deep sleep mode, thereby using a deep power consumption corresponding to a state in which the mobile phone is turned off. Additional functions can be used in the sleep mode, which reduces the power consumption and extends the battery life.
