A method of controlling a mobile terminal, and which includes turning on, via a controller of the mobile terminal, a global positioning system (GPS) engine to measure a position of the mobile terminal and provide a position-related service using the position measured by the GPS engine; sensing, via a sensor of the mobile terminal, a movement characteristic of the mobile terminal; temporarily turning off the GPS engine when the sensed movement characteristic of the mobile terminal is below a predetermined threshold; and turning back on the GPS engine when then sense movement characteristic is greater than or equal to the predetermined threshold.
