The present invention relates to a mobile communication terminal having a driveable time display function and a control method thereof.

Since the mobile communication terminal receives the driving power through the battery, the usage time is determined by the battery capacity. Therefore, the user should check the battery level and charge the battery at an appropriate time. When charging is not easy, the user should adjust the amount of usage to use necessary functions.

Thus, the current mobile communication terminal detects the battery level through a predetermined voltage check circuit and displays the battery level in the form of an icon in three to four steps so that the user can check the battery level. Thus, in the fully charged state, all of the bars of the battery icon are displayed in a filled state, and the remaining amount of battery information is provided in a form in which the bars of the battery icon are reduced by one as the use time elapses. In addition, the remaining capacity of the battery is displayed as a percentage of the total capacity to provide more accurate remaining information than the icon form. Thus, the user can check the approximate amount of battery remaining, and the user can determine by empirically guessing how much time can be actually driven.

On the other hand, the current mobile communication terminal is diversified in its use area by providing various additional functions such as a TV function, a game function, a camera function, as well as a telephone call function which is a unique function. These additional functions vary in power consumption depending on the amount of processor being processed and the hardware used. Therefore, there is a big difference in the available time depending on which function is used.

However, the conventional mobile communication terminal provides only approximate battery level information, and thus, there is a problem in that it is not possible to accurately grasp the actual usable time. In addition, there is a big difference in power consumption depending on the function being executed, and thus the battery power consumption decreases differently. Therefore, a uniform method or algorithm cannot calculate the exact usage time and it is not easy for the user to determine the available time. There is a problem.

The present invention has been made to solve the above-described problems, by real-time detecting the power reduction trend according to the use state of the mobile communication terminal to calculate the drive time for the remaining battery power, providing a reliable drive available time to the user's power An object of the present invention is to provide a mobile communication terminal having a driveable time display function for facilitating management and a control method thereof.

Hereinafter, a mobile communication terminal having a driveable time display function and a control method thereof according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

1 is a control block diagram of a mobile communication terminal having a driveable time display function according to the present invention. As shown in FIG. 1, the mobile communication terminal includes a system unit 10 for providing a communication function and an additional function, a battery 1 for supplying driving power to the system unit 10, and a battery 1. Detects the amount of current input from the system unit 10 to the control unit 12 of the system unit 10 and detects the voltage of the current sensing unit 3 and the battery 1 to control the control unit of the system unit 10 ( 12), wherein the control unit 12 is capable of driving according to the current mobile communication terminal based on the detection result through the voltage sensing unit 5 and the current sensing unit 3. The driving time is displayed on the display unit 16 by calculating the time.

The system unit 10 controls the RF module 14 for wireless transmission and reception of voice and data signals, a user input unit 18 for selecting a user, a display unit 16, and each of these components to make a phone call function. And a controller 12 providing other additional functions.

Here, the control unit 12 executes a telephone call function by controlling the RF module 14 or the like, and executes various application functions according to the user's selection through the user input unit 18 to execute various additional functions and the mobile communication terminal. And the data processing result and the like are displayed on the display unit 16. The control unit 12 may apply a mobile station modem (MSM) that performs a communication function and a control function.

The current sensing unit 3 is provided in the form of a variable resistor Rs interposed in a supply line of the system power inputted from the battery 1 to the system unit 10 so as to receive a resistance value according to the current supplied thereto. ) To the control unit 12.

The voltage detector 5 detects the voltage of the power supplied from the battery 1 and provides a detection value to the controller 12 of the system unit 10.

Accordingly, the control unit 12 calculates the current consumption through the resistance value Rs provided by the current sensing unit 3 and the voltage values V1-V2 provided by the voltage sensing unit 5. Here, the equation for calculating the current consumption may be set as follows.

<Calculation of Current Consumption>

The current sensed value and the voltage sensed value used in calculating the consumption current may use an average value within the corresponding time in units of a predetermined reference time, and the average value of the consumed current at the corresponding time is reflected by reflecting this in the <consumption current calculation formula>. Can be calculated. Accordingly, the controller 12 calculates the driving time for the current remaining amount of the battery 1 according to the calculated current consumption and displays the driving time on the display unit 16.

Here, the current consumption may vary depending on the currently running application, and even in the standby state, the current consumption may change according to the change in the wireless environment. Accordingly, the controller 12 calculates the amount of current consumption in each use state to calculate the drive time for the current remaining amount of the battery 1 so as to provide accurate drive time information.

2 is a flowchart illustrating a method for displaying a driveable time of a mobile communication terminal according to the present invention, which illustrates a case in which a driveable time is displayed when an application for providing an additional function is executed.

When the application is executed to provide additional functions such as a TV function or a game function (S10), the control unit 12 measures the voltage of the battery 1 through the voltage sensing unit 5 and the current sensing unit 3 and averages them. The current consumption value is calculated (S12). Here, the average current consumption value may be calculated through the above <consumption current calculation formula>, and if a separate current detection sensor is provided, it is also possible to use the detected value of the sensor as it is without a separate calculation process.

The controller 12 calculates the remaining amount of battery 1 according to the voltage of the battery 1 detected through the voltage sensing unit 5 (S14), and calculates an average current consumption value with respect to the calculated remaining amount of the battery 1. In operation S16, the driveable time of the currently running application is calculated. Since the average current consumption and the driving time that can be changed may vary from time to time depending on the amount of process being processed and the hardware in use, even if one application is running, the volume may be adjusted or the screen may be adjusted. The current consumption can vary. Therefore, when the calculation period of the driveable time is set short, the change in the current consumption is sensitively reflected, thereby increasing the accuracy of the driveable time information. On the other hand, in order to reduce the system load according to the calculation of the driveable time information, it is also possible to recalculate and display the driveable time only when a current amount variation occurs.

The control unit 12 displays the calculated application driving time in a predetermined area of the display unit 16 (S18), and determines whether the execution of the application continues (S20).

Accordingly, when the application is terminated, the display unit 16 switches to the idle state (S22), and if it is still running, calculates the driving time through the process of calculating the battery 1 voltage and the average current consumption value in step S12. The drive available time is displayed on the screen.

Here, even when the application is terminated and enters the idle state, the controller 12 may calculate and display the driving time of the mobile communication terminal by measuring the battery 1 voltage and the average current consumption. In this case, the user may recognize a change such as a rapid increase in current consumption due to a deterioration of the wireless environment so that the user can cope with it appropriately.

In addition, the driveable time may be always displayed in a predetermined region of the display unit 16, but a hotkey or a predetermined menu for confirming the driveable time may be provided to be selectively displayed only when the user wants to display the driveable time. It is possible.

3 is a diagram illustrating a driving time display state of a mobile communication terminal according to an exemplary embodiment of the present invention, and illustrates a case in which driving time information 100 is provided when viewing an image such as a TV through the mobile communication terminal.

As shown in FIG. 3, when the user selects a TV viewing function such as satellite broadcasting, the controller 12 executes the corresponding application to display a TV image on the display unit 16, while the current sensing unit 3 is displayed. And a current consumption and a voltage of the battery 1 through the voltage detector 5.

The controller 12 calculates a current consumption amount and current battery 1 remaining amount according to the execution of the TV viewing function by using the sensed voltage value and current value. The control unit 12 calculates and displays the driveable time 100 of the TV viewing function currently being driven on the display unit 16 using the calculated current remaining amount of the battery 1 and current consumption. Thus, the display unit 16 may display the driving time 100 in detail, such as "180min," so that the user may appropriately manage the power of the battery 1.

As described above, the present invention is to detect the change in the current consumption according to the execution of various functions of the mobile communication terminal to display the driveable time to execute the function for the remaining battery.
