Mobile communication terminal and method for warning a user of a low-voltage state of the same
First Claim
1. A method for warning a user of a low-voltage state of a mobile communication terminal, comprising the steps of:
- a) pre-storing a Short Message Service (SMS) or Out-Going Message (Voice OGM) low-voltage alarm message in a memory;
b) checking a voltage level of a battery in a call connection mode; and
c) if the voltage level of the battery is lower than a predetermined voltage, reading the low-voltage alarm message from the memory, transmitting the read low-voltage alarm message to a called terminal communicating with the mobile communication terminal, and selecting one of the SMS message and the Voice OGM;
if the SMS message is selected, transmitting the low-voltage alarm message to the called mobile communication terminal using the SMS message; and
if the Voice OGM is selected, transmitting the Voice OGM to the called terminal through a traffic channel.

Abstract
A mobile communication terminal and a method for warning a user of a low-voltage state of the terminal. The method includes the steps of pre-storing a low-voltage alarm message in a memory, checking a voltage level of a battery in a call connection mode, and if the voltage level of the battery is lower than a predetermined voltage, reading the low-voltage alarm message from the memory and transmitting the read low-voltage alarm message to a called terminal communicating with the mobile communication terminal. A caller mobile communication terminal can thus inform a called mobile communication terminal that the breaking of a call connection state was caused by a low-voltage state of a battery of the caller terminal.

9. A mobile communication terminal apparatus, comprising:
-
a voltage detector for detecting a battery voltage; a message storage unit for storing a low-voltage alarm message therein; and a controller for transmitting the low-voltage alarm message to a called terminal when the battery voltage is lower than a predetermined voltage, wherein the controller determines whether a phone number of the called terminal is a mobile communication phone number or a fixed line phone number, transmits a Short Message Service (SMS) message as the low-voltage alarm message when the phone number of the called terminal is a mobile communication phone number, and transmits a Out-Going Message (Voice OGM) as the low-voltage alarm message when the phone number of the called terminal is a fixed line phone number. - View Dependent Claims (10, 11, 12, 13)
