PURPOSE: A logic device of a mobile communication terminal is provided to mount one LED(Light Emitting Diode) in left/right sides of the terminal, respectively, thereby enabling a user to easily recognize a number of a receiving terminal. CONSTITUTION: A transceiver(52) transceives a call signal. A controller(54) sets a telephone number of a receiving terminal, to compare the set telephone number with a telephone number transmitted from a transmitting terminal, and checks whether a corresponding telephone number exists. A switch controller(56) controls an LED of the corresponding telephone number under the control of the controller(54). LEDs(58,60) are switched under the control of the switch controller(56) and are driven. When a ring signal is inputted through the transceiver(52), the controller(54) checks the received telephone number and the set telephone number. The controller(54) sets two telephone numbers, and pre-stores the telephone numbers in a memory. The controller(54) turns on the LEDs(58,60) of the corresponding telephone by controlling the switch controller(56), and drives the LEDs(58,60).
