The present invention relates to a portable terminal, and more particularly, to an apparatus and a method for controlling a battery remaining amount of a portable terminal.

As the industry develops and the area of human activity and activity increases, the means of mobile communication is revolutionizing to support the convenience of users. Innovative development has led to the invention of a portable terminal that is a portable and portable device, a representative device of mobile communication means, and the invention of such a portable terminal allows users to communicate with mobile phones anywhere and everywhere. .

The portable terminal can conveniently communicate with a user at any place while moving, and examples thereof include a cellular phone, a PCS, a PDA, a smart phone, and the like.

The portable terminal uses a rechargeable battery that stores and supplies energy to support mobility and portability as a power supply.

The rechargeable battery determines how much user convenience can be provided according to the remaining battery capacity. Of course, the main concern is how long the battery can be used and how long the battery can be used. . In the conventional method of displaying the remaining battery level, an icon similar to a conventional battery (primary cell) shape is displayed as the remaining battery level in use. The remaining battery indication of the conventional portable terminal is shown in FIG.

FIG. 1 is a view illustrating an external appearance of the portable terminal 100, which includes a liquid crystal display (LCD) 120, a battery level display 110, and a keypad 130. At this time, the remaining battery indication of the portable terminal 110 is displayed in the form of a battery (primary battery) as shown in (a), (b), (c) of FIG.

That is, area (a) of FIG. 1 represents battery remaining when there is a large amount of battery remaining, and area (b) of FIG. 1 represents battery remaining when half remaining of battery remains. In FIG. 1C, the battery remaining amount is expressed when the battery has almost no remaining amount.

Referring to FIG. 1, in the related art, the battery remaining amount represented by an icon resembling the shape of a battery (primary cell) is displayed by dividing the battery remaining into three to four spaces. However, the space is reduced, but the approximate amount of battery remaining, but it is difficult to determine the exact problem. Also, the longer you use it, the less time this cell shrinks, and the user needs to predict the remaining battery life by experience.

In addition, in the related art, the portable terminal is implemented such that various functions of the terminal can be used without any limitation when the power of the battery is higher than a certain level.

As a result, a battery may be depleted using one function and there may not be enough battery for other important functions.

That is, as an example, there is a disadvantage in that an uncomfortable case in which the battery is completely consumed while the game function of the portable terminal is fully consumed and the call waiting cannot be made.

The present invention is to indicate the remaining battery power of the portable terminal, by specifying a battery power level of a plurality of levels for each function to maintain the battery power to use the important functions of the terminal by terminating the warning and reaching the program when the level is reached Another object of the present invention is to provide an apparatus and method for controlling a battery level of a portable terminal, which provides a user's convenience by leaving extra batteries for important functions.

In order to achieve the above object, a method of controlling a battery remaining amount of a portable terminal according to an embodiment of the present invention includes a level (third and fourth level) value of a residual amount of battery basically required for a first function of the portable terminal. Stored; When the second function of the portable terminal is executed by the user's selection, storing the level (first and second level) values for the remaining battery level at which the limit of the execution of the second function is set in the memory; If it is detected that the remaining battery level reaches the first level during the execution of the second function, displaying a warning message for terminating the second function; And if it is detected that the second function is continuously executed to reach the second level, the second function is automatically terminated.

Here, the first function includes a call waiting or a call function as an important function of the portable terminal, and the second function includes a game or media play function as an additional function of the portable terminal.

The method may further include retrieving a battery remaining amount of the portable terminal in real time by the battery measuring unit.

The method may further include: displaying a warning message indicating that the first function is to be terminated when it is detected that the remaining battery level corresponds to a third level position during the execution of the first function; When the fourth level is reached, this means that the battery power is exhausted, and further comprising the step of automatically terminating the first function.

In addition, the remaining amount of the battery corresponding to the third level is characterized in that less than or equal to the remaining battery of the second level. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic internal block diagram of a portable terminal to which the present invention is applied, and FIG. 3 is a battery remaining indication displayed on a display unit.

Referring to FIGS. 2 and 3, the display unit 212 displays state information such as the overall state of the portable terminal, input numbers and letters, messages to be written, phone numbers to be searched, and the like. It is implemented as a liquid crystal display (LCD). In the case of the present invention, the battery level indicator, which is represented by an icon resembling a battery shape, is provided in a predetermined region of the display unit 212.

However, in the case of the present invention, not only can the battery remaining amount be divided into 3 to 4 spaces, but also the battery remaining value measured in real time by the battery measuring unit 224 provided therein is not divided into predetermined steps continuously. It can be expressed as.

In addition, the memory 214 stores a variety of data of the portable terminal, in the embodiment of the present invention is characterized in that the remaining level value of the battery capable of performing a predetermined function is stored.

For example, a battery level level value for delivering a warning message for maintaining a standby battery power and a service termination required to perform a call waiting and a call, which are basic functions of a portable terminal, is stored, and another application for maintaining the main battery power is stored. The battery's remaining level value is stored for the delivery of warning messages and the end of service.

That is, the present invention periodically checks the remaining battery level through the battery measuring unit 224 and displays a warning message when the remaining battery level is lower than the specified level, and terminates the service when the battery level falls further.

Through this, the present invention specifies a battery power level of a plurality of levels for each function (eg game, media play) to maintain the battery power to use important functions (eg, call waiting, call) of the portable terminal. It is characterized by maintaining the basic level of the battery by warning and reaching the end of the program when reaching.

Accordingly, when it is detected by the battery measuring unit 224 that the remaining battery level corresponds to the first level position of the battery display, a warning message for terminating the currently used function is displayed, and the second level position is displayed. If it is found, the current function is automatically terminated. However, since a plurality of application functions of the portable terminal are provided, the level value for the function may be stored separately for each function.

This is to maintain a minimum battery level for the important functions of the portable terminal.

The minimum battery remaining level value for the important function is also stored in the memory 214, and accordingly, the battery remaining amount corresponds to the third level position of the battery display by a real-time search by the battery measuring unit 224. If this is found, a warning message is displayed indicating that the important function currently in use is soon to be terminated, and the important function currently in use is automatically terminated when the fourth level position, that is, the power is exhausted.                     

In addition, the wireless signal processing unit 220 performs overall processing for transmitting and receiving wireless signals between the mobile terminal and the base station, and converts a signal in a radio frequency band into an intermediate frequency and converts the converted intermediate frequency into a baseband signal. It performs the operation and converts the converted baseband signal into a digital signal to perform the corresponding processing.

The battery measuring unit 224 sends data to the battery 234 using the current battery remaining amount checking chip (chip) to measure the remaining amount of the battery in real time.

The key input unit 232 includes a plurality of numeric keys and function keys, and is used for setting and performing a function required through input of information input means and keys of a user.

The battery 234 supplies operating power to the respective functional units of the mobile terminal, and the controller 222 collectively controls the overall operation of each functional unit of the mobile terminal.

4 is a flowchart illustrating a method of controlling a battery remaining amount of a portable terminal according to an embodiment of the present invention.

Referring to FIGS. 2 to 4, first, a level value of a battery remaining basically required for important functions (eg, call waiting and call) of a portable terminal is stored in a memory. (ST 40)

This may be set directly by the user, but is preferably set as a default at the time of manufacture.

Thereafter, the user's selection executes a specific function of the portable terminal. At this time, if an additional function (eg, game, media play, etc.) other than the important function of the terminal is executed, the limit of execution of the additional function is limited. The level value for the remaining battery level is stored in the memory. However, since a plurality of application functions of the portable terminal are provided, the level value for the function may be stored separately for each function. (ST 41, 42)

This may also be set by the user himself, but is preferably set as a default at the time of manufacture.

If the user reaches the predetermined level value of the remaining battery level stored in the memory, that is, the first level while using the additional function of the terminal, by the real-time search by the battery measuring unit 224, the additional function currently used A warning message is displayed to exit. (ST 43, 44)

In spite of the message, if the battery remaining in the memory reaches the second level by the user continuously executing the additional function, the current additional function is automatically terminated. (ST 45, 46)

As such, the remaining battery level is maintained for important functions of the terminal after the additional function is automatically terminated.

Accordingly, when the terminal performs an important function, the battery measuring unit 224 searches for the remaining amount of the battery in real time.

As a result, when it is detected that the remaining battery level corresponds to the third level position of the battery display, a warning message is displayed indicating that the important function currently used is soon to be terminated. (ST 47, 48)                     

Here, the remaining battery level of the third level is less than or equal to the remaining battery level of the second level.

If the battery remaining in the memory reaches the fourth level while performing the important function afterwards, this means that the battery power is exhausted, and the important function currently used is automatically terminated. (ST 49, 50)

According to the present invention, in order to maintain the battery power to use the important functions of the terminal, by specifying a battery power level of a plurality of levels for each function to cause the warning and the program to terminate when the level is reached, the battery in the portable terminal Management can be effectively performed by function, and accordingly, there is an advantage that a user can use the terminal conveniently and safely by leaving an extra battery for important functions.
