ABSTRACT:
A method for automatically switching an incoming call signal output mode in a mobile communication terminal is disclosed. The method comprises the steps of determining whether or not a present incoming call signal output mode is a vibration mode when receiving incoming call, driving a vibrator to output vibration if it is determined that the present incoming call signal output mode is set to the vibration mode, detecting an intensity of actual vibration of the terminal via a vibration detection sensor when the vibration is output, followed by calculating transfer energy using the intensity of the actual vibration on the terminal, and automatically switching the incoming call signal output mode from the vibration mode to a ringtone mode according to comparison of the calculated transfer energy with a reference value. With the method, a user can easily recognize the incoming call signal.
