Abstract: An apparatus and method for automatically setting a vibration mode of a mobile terminal using infrared signals and a method therefor. The apparatus determines whether or not the infrared signals are inputted by an infrared signal receiving section. A data content of received infrared signals is interpreted by a control section. The control section then switches the mobile terminal between a vibration mode and a previous incoming call mode according to the resultant interpretation of the data content. Accordingly, a mobile phone may be placed in a vibration mode automatically upon entering a public place requiring silence, and may be switched back to the previous incoming call receiving mode upon exiting the public place.
