Abstract
Provided are a system and a method for reducing a communication load of an apparatus for tracking a moving object. The system includes: an estimated necessary time calculating unit receiving a current location and an arrival location of the moving object from a terminal included in the moving object, calculating estimated necessary time for the moving object to reach the arrival location, and transmitting the estimated necessary time to the terminal; and a communication path on-off controlling unit activating a communication path for the terminal to receive the estimated necessary time from the estimated necessary time calculating unit, and inactivating the communication path when the terminal receives the estimated necessary time through the communication path.
