System For Diminishing the Load of Platform Which Traces the Location of Moving Objects and Method Thereof
First Claim
1. A system for reducing a communication load of a platform for tracking a moving object, the system comprising:
- an arrival time prediction unit receiving a current location and an arrival location of the moving object from the moving object, calculating estimated arrival time for the moving object to reach the arrival location, and transmitting the estimated arrival time to the moving object;
a terminal which is located in the moving object, receiving the estimated arrival time and determining an estimated location; and
a communication path on-off controlling unit inactivating a communication path for reporting the current location and the arrival location from the moving object when the terminal receives the estimated arrival time is received, and activating the communication path when the estimated arrival time has to be newly calculated again.

Abstract
In existing moving object tracking, there is a great communication load between a terminal and a platform, because the terminal should report its location to the platform every second or every minute and the platform should frequently process the location form the terminal. It is possible to reduce the great communication load on the server, by calculating an error between the current GPS location and the estimated location at a specific time on the basis of the estimated arrival time of the moving object. It allows that the terminal report its location to the server only when the error between current GPS location and the estimated location is greater than a predetermined threshold value.

6. A method of reducing a communication load of a platform for tracking a moving object, the method comprising:
-
(a) receiving a current location and an arrival location of the moving object, calculating an estimated arrival time for the moving object to reach the arrival location, and transmitting the estimated arrival time to the moving object; (b) transmitting the estimated arrival time to a terminal of the moving object and allowing the terminal, which is located in the moving object, to determine an estimated location of the moving object; and (c) inactivating a communication path through which the moving object reports the current location and the arrival location to the platform when the terminal receives the estimated arrival time. - View Dependent Claims (7, 8, 9)
