PURPOSE: A method for controlling power supply in a place incapable of speech, is provided to reduce a use of power supply in a serve incapable place, by lowering transmission power supply to a predetermined level when receiving field strength, measured by checking a signal received to a terminal, is under a predetermined value. CONSTITUTION: A method for controlling power supply in a place incapable of speech comprises the steps of: measuring receiving field strength(a first step); outputting transmission power supply to a predetermined level when the measured receiving field strength is under a predetermined value, and returning to the first step(a second step); checking whether the measured receiving field strength is increased more than formerly measured receiving field strength when the measured receiving field strength is not under a predetermined value(a third step); lowering transmission power supply when the measured receiving field strength is increased more than the formerly measured receiving field strength, and returning to the first step(a fourth step); raising transmission power supply when the measured receiving field strength is decreased than the formerly measured receiving field strength, and returning to the first step(a fifth step); and returning to the first step when the measured receiving field strength is equal to the formerly measured receiving field strength(a sixth step). |
