A preferred embodiment of the apparatus and method for displaying the available time of a mobile communication terminal according to the present invention will be described with reference to FIGS. 2 and 3 as follows. First, Figure 2 is a block diagram showing a call available time display apparatus of a mobile communication terminal according to the present invention.

As shown in FIG. 2, the battery 204, the LCD 206, and the RF module 208 are organically connected to each other around the central processing unit 202. One function of the central processing unit 202 is to check the remaining amount of the battery 204 and display it on the LCD 206 which is a display device.

The counter 210 receives the state information of the battery from the CPU 202 and counts it to detect the remaining battery level. The memory 212 is a kind of lookup table, and stores information on the relationship between the magnitude of the transmission power and the remaining amount of the battery. That is, in the memory 212, the relationship between the amount of current consumed for the predetermined amount of transmission power is converted into reference data and stored.

The central processing unit 202 detects the amount of remaining battery power and the required transmission power, and calls the current battery level by referring to the relationship information between the required transmission power stored in the memory 212 and the remaining battery power. Calculate the maximum time you can. The maximum talkable time calculated by the central processing unit 202 is displayed via the LCD 206.

When the CPU 202 detects the remaining battery level, it checks the state of the current battery. First, the CPU 202 checks whether the battery is currently being charged, and when the battery is being charged, the current charge level is checked. Next, check whether the battery is fully charged and count the remaining battery when it is not fully charged. In either case, the available talk time for the remaining battery is calculated to display the maximum talk time.

The operation of the available time display device of the mobile communication terminal according to the present invention will be described with reference to FIG. 3 is a flowchart illustrating a method for displaying a call available time of a mobile communication terminal according to the present invention.

As shown in FIG. 3, the method for displaying the available calling time of the mobile communication terminal according to the present invention may be divided into a case of using a charged battery and a case of charging being performed. When the charged battery is used, it may be divided into a fully charged battery and a used battery, and when the charging is in progress, it may be divided into a case where the charging is completed and a charging is in progress.

In the standby state 302 of the mobile communication terminal, when a key input for checking the maximum available time for the battery level occurs (304), the CPU checks the current state of the battery (306), and checks the battery state at this time. Is to check if the battery is charging.

If it is determined that the battery is being charged (308), and if not charging again to check the current state of the battery (310), the battery status check at this time is to determine whether the battery is fully charged (312). If the battery is fully charged, the maximum available talk time for the battery level is calculated (314) and output to the LCD (316). Returning to the second battery status checking step 312, when the battery is not fully charged, the counter counts the remaining battery capacity (318) to calculate the maximum talk time for the remaining battery capacity (314) and outputs to the LCD. (316).

Returning to the first battery status check step 308, if the battery is being charged, the current charge level is checked (320). If the battery is fully charged by determining whether the battery is fully charged, the maximum call for the remaining battery level is made. In step 314, the available time calculation step is performed. If the current state is being charged, the current charge amount is counted (324), and then the maximum talk time for the remaining battery level is calculated (314). The calculated maximum talk time is output to the LCD (316).
