METHOD OF ACQUIRING INITIAL GPS SIGNAL IN BROADCASTING SYSTEM AND SYSTEM USING THE METHOD
First Claim
1. A Digital Multimedia Broadcasting (DMB) system for providing a service by dividing an entire broadcasting service area into at least one area, the DMB system comprising:
- an Assisted Global Positioning System (AGPS) server for generating Acquisition Assistance (AA) data distinguished according to an area based on a pre-set position of each service area;
a transmitting station for broadcasting the AA data; and
at least one terminal for acquiring an initial GPS signal by receiving the broadcasted AA data.

Abstract
A system and method for acquiring an initial Global Positioning System (GPS) signal in a communication system including a terminal. The system includes an Assisted GPS (AGPS) server for generating Acquisition Assistance (AA) data distinguished according to an area based on a pre-set position of each service area, a transmitting station for broadcasting the generated AA data to terminals, and the terminals for acquiring an initial GPS signal by receiving the broadcasted AA data. In addition, the method includes the steps of generating AA data distinguished according to an area based on a pre-set position of each service area, broadcasting the generated AA data to terminals, and acquiring, by each of the terminals, a GPS signal by receiving the broadcasted AA data.
