Description

How to display the current consumption according to the operating state of the mobile communication terminal

The present invention relates to a method for displaying current consumption in a mobile communication terminal, and more particularly, to a method for relatively displaying current consumption according to an operating state of a mobile communication terminal.

In general, the mobile communication terminal detects power (or an electric field) received from a base station and controls power for outputting a radio signal. The strength of the electric field received from the base station to the mobile communication terminal varies depending on the electric field environment. Accordingly, the strength of power for transmitting a radio signal varies according to the electric field environment. This means that the current consumption from the battery depends on the electric field environment. In other words, if the mobile communication terminal is in an area where the hand-off is frequently performed (the border area of the base station) or when a call is made in a weak electric field such as a building or a mountainous terrain, the mobile communication terminal is located in the slot mode of 1 area. If so, the battery's current consumption will increase, resulting in shorter battery life.

In general, manufacturers supplying mobile communication terminals present users with battery life. However, there is a difference between the use time suggested by the manufacturer and the use time actually used by the user. This is because the usage time suggested by the manufacturer is the usage time based on the standard current consumption, and the current consumption actually consumed by the user depends on the electric field environment as described above.

Therefore, when the user uses the mobile communication terminal based on the usage time suggested by the manufacturer, the battery is consumed earlier than the suggested use time, so that the user cannot use the mobile communication terminal while moving.

Accordingly, an object of the present invention is to provide a method for displaying the current consumption of a mobile communication terminal at a graphic level according to a call state.

Another object of the present invention is to provide a method of dividing a current consumption of a mobile communication terminal into a plurality of stages according to a call state and displaying the moving speed at a graphic level.

In order to achieve the above object, the present invention provides a method for displaying a current consumption amount of a mobile communication terminal, the first process of checking whether the artificial idle state when the power is on, and the number of icons if the artificial idle state in the first process Displaying a current consumption amount by moving the first group having a second state, determining whether the device is in a sleep state if it is not an artificial idle state, and displaying a current consumption amount by moving the second group having the number of icons when the sleep phase is in the second process. And a third process of determining whether the slot cycle is in an idle state if not in the sleep state, and displaying a current consumption amount by moving to a third group having the number of icons in the third process if the slot cycle is in the idle state. A fourth step of checking whether a call is in progress, and a reception electric field of a signal received when the call is in the fourth step A fifth process of detecting an intensity and determining whether the received field strength is greater than or less than a predetermined reference received field strength; and if the received field strength detected in the fifth process is greater than the reference received field strength, a fifth number having a predetermined number of icons. The sixth step of displaying the current consumption in the field of the strong electric field by the four-group movement, and displaying the current consumption of the weak field in the fifth group movement having a predetermined number of icons if the small group.

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

The microprocessor 10 controls the overall operation of the mobile communication terminal. The microprocessor 10 includes a timer 15 therein, and the timer 15 sets and counts various times of the mobile communication terminal. The memory 20 includes a ROM for storing a predetermined operating program, a RAM for temporarily storing data generated during execution of the operating program, and an electronically programmable EEPROM. The key input unit 30 includes a menu key for displaying a menu, a function key for setting a plurality of functions, and a numeric key for dialing, and outputs key data for the keys to the microprocessor 10. The display unit 40 receives and displays display data on key data input by the key input unit 30 from the microprocessor 10, and displays characters and icons indicating an operation state and a plurality of information of the mobile communication terminal. The flip open detecting unit 50 detects the opening and closing of the flip using a magnetic field in the flip type mobile communication terminal. The RF unit 60 modulates and demodulates a radio signal transmitted and received through an antenna. The received field strength detection unit 65 detects the received field strength of the radio signal received by the RF unit 60 and outputs the received field strength to the microprocessor 10. At this time, the microprocessor 10 displays the received electric field strength on the display unit 40 as a graphic or icon. The baseband unit 70 converts the analog-type intermediate frequency signal demodulated by the RF unit 60 into a digital signal form and outputs it, and converts the digital-type signal input from the signal processing unit 80 described below into an analog-type intermediate frequency signal. Output The signal processor 80 converts the voice signal input through the microphone (MIC) into a PCM signal in the form of a digital signal, and compresses and reconstructs the PCM signal to the baseband unit 70. In addition, the signal processor 80 restores the channel-compressed digital signal input from the baseband unit 70 to the original signal and outputs the audio signal through the speaker SP. The digital type signal is a signal obtained by channel compression of a PCM signal by QCELP in case of Code Division Multiple Access (CDMA) method and VCELP in case of Time Division Multiple Access (TDMA) method. to be.

FIG. 2 is a diagram illustrating a screen of a liquid crystal display (LCD—hereinafter referred to as a “display unit”) displaying the current consumption amount according to an embodiment of the present invention.

The display unit 40 has a current consumption amount display area 30 for displaying the current consumption in each state by text and a current consumption icon display area 301 for displaying the current consumption amount with an icon. According to the present invention, both display areas 301 and 303 may be provided, and only one of the two display areas 301 and 303 may be displayed. As an icon displayed in the current consumption icon display area 301, an icon such as a bar or a dot may be used. The number of icons increases with each current consumption state of the mobile communication terminal. That is, the number of icons increases as the current consumes more, and the icons move in the current consumption icon display area. The moving speed of the icon is proportional to the number of icons.

3 is a diagram showing an example of displaying the current consumption amount displayed on the display unit according to each state of the mobile communication terminal. 3 (A) shows the current consumption in the sleep state. Since the current consumption is the minimum, it is indicated by the movement of one dot. (B) shows the current consumption in the slot cycle idle state, and the current consumption in the slot cycle idle state is indicated by two dot movements. The slot cycle idle state is a state in which the RF unit 60 is turned on periodically to check whether there is a call received from the sleep state. (C) shows the current consumption in the artificial idle state, and the current consumption is represented by three dot movements. The artificial idle state is a state in which the flip is opened while the key of the key input unit 30 is input or the flip is closed. In the artificial idle state, the display unit 40 lights up to indicate that current consumption increases. And (d) and (e) show the current consumption in the call state, (d) shows the current consumption in the strong electric field state, (e) shows the current consumption in the weak electric field state. In the strong electric field state of (D), it is indicated by four dot movements, and in the weak electric field state of (E), it is indicated by five dot movements. This is because the mobile communication terminal transmits power in proportion to the power received from the base station, so that the power received from the base station is divided into a strong electric field and a weak electric field based on a predetermined reference electric field intensity level, and thus represents the current consumption. will be. The dots are grouped by the number of dots according to each state and moved at a moving speed proportional to the number of dots.

As described above, the amount of current consumption in each state increases in the order of sleep state → slot cycle idle state → artificial idle state → strong electric field state → weak electric field state, and thus the number of dots is one dot → two dots → three dots → four dots. → Increases to o dots. And the moving speed of the dot is also faster in order of the current consumption amount.

4A and 4B are flowcharts illustrating a current consumption display method according to an operating state of a mobile communication terminal according to an exemplary embodiment of the present invention.

Hereinafter, referring to FIGS. 1, 2, and 3, in operation 201, the microprocessor 10 checks whether power is turned on. When the power is turned on, the microprocessor 10 detects this and proceeds to step 203 to display the current consumption in the artificial idle state as shown in (c) of FIG. 3 in the current consumption icon display area 301. If the current consumption of the artificial idle state is displayed, the microprocessor 10 checks whether the flip is closed in step 204. If the flip is closed in step 204, the microprocessor 10 proceeds to step 205 and displays the current consumption in the sleep state as shown in FIG. If the flip is closed and the current consumption in the sleep state is displayed, the microprocessor 10 proceeds to step 207 to check whether the flip is open. In this case, when the flip is opened, the microprocessor 10 returns to step 203, and if the flip is not opened, the microprocessor 10 proceeds to step 209 and checks whether the timer exceeds the first predetermined time (sleep state maintenance time) through the timer 15. If the flip is not opened, the microprocessor 10 continues to display the sleep state current consumption for the first predetermined time, and if the first time exceeds the first predetermined time, the microprocessor 10 proceeds to step 211, and the current consumption icon of the display unit 40 is shown in FIG. Displays the slot cycle idle state current consumption as in (B). At this time, the time in the slow cycle idle state is counted by the timer 15, and the microprocessor 10 checks whether the time counted by the timer 15 exceeds the second predetermined time (slot cycle idle state holding time). If the second predetermined time is exceeded, the microprocessor 10 returns to the sleep state and proceeds to step 205 to display the sleep state current consumption in the current consumption icon display area 301.

In operation 204, the microprocessor 10 proceeds to step 215 and checks whether a key is input by the key input unit 30. If the key is input from the key input unit 30, the microprocessor 10 proceeds to step 219. If the key is not input, the microprocessor 10 proceeds to step 217. The time counted from the power-on time is the third predetermined time (artificial idle state holding time). Check if it exceeds. If the time counted from when the power is turned on exceeds the third predetermined time, the microprocessor 10 proceeds to step 205 and displays the sleep state current consumption amount in the current consumption icon display area 301 again. If the count time does not exceed the third predetermined time, the process returns to step 204 to repeat the above process.

When a key is input in the key input unit 30 in step 215, the microprocessor 10 proceeds to step 219 to check whether the input key is a call key. If the input key is a call key, the microprocessor 10 proceeds to step 221 to form a call path, and in step 223, detects a received electric field strength (RSSI) and displays the detected received electric field strength on the display unit 40. The detection and display of the received electric field strength is continuously displayed from the time of power on, but is shown in FIG. When the received electric field strength is displayed on the display unit 40 in step 223, the microprocessor 10 proceeds to step 225 to check whether the detected received electric field strength is greater than the reference received electric field strength. The reference received field strength is for dividing the signal received from the base station into a weak field and a strong field. If the detected electric field strength is less than the reference electric field strength as a result of the inspection, the microprocessor 10 proceeds to step 229 and displays the current consumption of the weak electric field state as shown in (e) of FIG. 3 in the current consumption icon display area 301. . However, if the received electric field strength detected in step 225 is greater than the reference received electric field strength, the microprocessor 10 proceeds to step 227 to display the current consumption of the strong electric field state as shown in (d) of FIG. 3 in the current consumption icon display area 301. Display. When the state of the strong electric field or the call of the weak electric field is reached, the microprocessor 10 checks whether the call is terminated in step 231. If the call does not end in step 231, the microprocessor 10 repeats the process after step 225, and when the call ends, proceeds to step 233 to check whether the power is turned off. If the power is not turned off in step 233, the flow proceeds to step 203 to display the current consumption in the artificial idle state on the current consumption icon display area 301, repeats the process after step 203, and ends the process when the power is turned off. do.

As described above, the present invention has an advantage of allowing the user to recognize the current consumption amount by graphically displaying the current consumption amount according to the operation state of the mobile communication terminal, thereby estimating the consumption state of the battery.

In addition, the present invention has the advantage of being able to estimate the state of charge of the battery to match the charging time of the battery.
