In other words, it is possible to predict the discharge time of the battery in advance to prevent the inconvenience, such as work interruption accordingly.

In particular, portable communication devices such as mobile communication terminals are supplied with operating power through the use of batteries due to the property of performing a call over the air in a portable state. Therefore, how much time the battery can be used and how long it can be used is a major concern for users.

However, the conventional mobile communication terminal does not display the battery remaining amount and the use time in detail, which makes the user feel uncomfortable in many ways.

In the conventional battery level display method, the icons are divided into upper, middle, and lower positions, and the user is aware of the remaining battery level as the display state of the corresponding icon. This display method allows the user to know the exact remaining amount and the estimated usage time accurately. Could not.

In particular, when a relatively long call connection time is required such as data communication, the battery remaining amount and the estimated usage time need to be displayed more accurately.

When the mobile terminal is set to the ringer mode, if the battery level is low during a call, an alarm will sound to give you time to prepare for the other party or the caller yourself, but in the Vibrate / Silent / Manor mode, There is a problem that a sudden interruption of the call occurs without any warning other than the blinking of the battery icon.

The present invention is to solve the problem of the method of displaying and managing the remaining battery level of the conventional mobile communication terminal as described above, when the low battery is detected during the call using the mobile terminal mixing the sound pressure is adjusted to the warning tone It is an object of the present invention to provide a warning device and a method according to the battery state of the mobile communication terminal to prevent the sudden interruption of the call by outputting.

Here, the mode switching unit is characterized in that the switch to automatically switch to the ringtone output mode when the user needs to pay attention to the battery remaining in the state set in the vibration / silent / silent mode.

According to another aspect of the present invention, there is provided a warning method according to a battery state of a mobile communication terminal, when a low battery signal is detected while a user makes a call with another subscriber; If the output mode is not the ringtone output mode, switching to the ringtone output mode; Adjusting the sound pressure of the warning signal output from the ringtone output mode; Mixing the sound pressure-adjusted warning signal and the call voice to output to the user It is characterized by including.

Here, the sound pressure control is preferably adjusted to be lower than the sound pressure of the warning signal output in the normal ringtone output mode.

The sound pressure-adjusted warning signal is mixed with the call voice and output, and after the call is terminated, the terminal is powered off.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of the embodiments.

Referring to the accompanying drawings, a preferred embodiment of the warning device and method according to the battery state of the mobile communication terminal according to the present invention will be described in detail as follows.

1 is a block diagram of a mobile communication terminal according to the present invention.

The present invention improves the low battery warning during a call as a sound only in the ring tone setting state, and when the terminal is set to vibrate / silent / silent mode, the battery remaining is insufficient to pay attention to the user automatically. Switch to ring mode to give a beep.

The configuration includes an RF module 11 for performing RF signal processing, an analog baseband part 12 for processing a signal of an analog band received through the RF module, and outputting a call voice; A digital band processor 13 for checking a voltage of the battery 14 and processing and outputting a signal of a digital band, a sound source (MIDI; Musical Instrument Digital Interface) processor 16 and a digital band processor for processing sound sources such as ringtones. A mode switching unit 15 configured to switch an output signal of the digital band processor 13 in accordance with modes such as a vibration mode, a silent mode, a manner board, other silent modes, a ring tone output mode, and the like; Is set to vibrate / silent / silent mode to alert the user when the battery level is low. It is included for the resistor 17 and the analog-band processing unit 12, signal mixer 18 for output to the receiver (receiver) by mixing a voice call and the sound pressure level in the low control alarm that is output in the configuration.

According to the present invention, after the terminal is set to not make a ringtone during a call such as a vibration / silent / silent mode, the user automatically switches to a ringtone (which can make any sound) during the call until the battery level is low. Attention is given to the other party or the user to be prepared for the battery consumption.

At this time, if the warning sound is too loud to hear the other party's sound incorrectly during the call, and to prevent the sound that the other party hears the warning sound (Echo), a sound pressure control element is configured to sufficiently lower the warning sound and mix with the sound of the call. .

An example of a warning method according to a battery state of a mobile communication terminal according to the present invention having such a configuration is as follows.

2 is a flowchart illustrating a warning control according to a battery state of a mobile communication terminal according to the present invention.

The warning control method according to the battery condition according to the present invention automatically switches the current mode to the ringtone output mode and outputs a warning sound when a low voltage difficult to make a call in the silent / vibration / silent mode is detected. After the warning, the terminal power off.

First, as shown in FIG. 2, the user starts a call with another subscriber (S201), and continuously performs a step of detecting the remaining battery level, so that the remaining battery is insufficient to determine that it is difficult to make a normal call. If a signal is detected (S202), it is determined whether the current output mode is one of silent, vibration, and manner. (S203)

If the current output mode is not one of silent / vibration / manner, the warning sound is output in the normal ring tone output mode, and if the current output mode is one of silent / vibration / manner, Switch the output mode of the ring tone output mode. (S204)

Then, the sound pressure output is lowered through the sound pressure adjusting element of the output signal output from the sound source processor (S205).

In addition, the voice signal output from the analog band processor is mixed with the output signal of the sound source processor of which the sound pressure is lowered (S206).

In this way, after mixing the output signal of the sound source processor of which the sound pressure is lowered to the call voice, the mixed signal is output through the receiver (S207).

As such, a call voice and a warning sound are output to allow the user and the other party to recognize the current battery state that it is difficult to continue the call, and then turn off the terminal when the call ends.

The warning control method according to the battery state according to the present invention, when a low voltage is difficult to make a call in silent / vibration / silent mode is detected, the current mode is automatically switched to the ringer output mode so that a warning sound is output along with the call voice. You can prevent the terminal from turning off suddenly during a call.

This gives users and counterparties time to efficiently cope with lack of battery power, thereby reducing discomfort during the call.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.

The warning device and method according to the battery state of the mobile communication terminal according to the present invention has the following effects.

First, when a low voltage that is difficult to make a call in silent / vibration / silent mode is detected, the current mode is automatically switched to a ringer output mode, and a warning sound is output along with the voice of the call so that the user can effectively cope with low battery. .

Second, in the silent / vibration / silent mode, the phone is suddenly disconnected due to low battery during the call and the terminal is turned off to minimize the inconvenience of the call.

Third, when the automatic switching to the ring mode, the sound pressure of the warning sound is adjusted and output, so that the user and the other party can receive a proper warning without any feeling of rejection.
