摘要：A method for creating acquisition assistance information (AA data) for acquiringof a global positioning system (GPS) signal in an assisted global positioning system(AGPS) is provided. The method includes receiving repeater information included in amobile communication network of a terminal whose location is to be measured, inresponse to a request for the acquisition assistance information for the GPS signal fromthe terminal, determining a repeater delay caused by a repeater that is present betweenthe terminal and a base station that is synchronized with the terminal using the repeaterinformation, and creating the acquisition assistance information for the GPS signal of theterminal based on the repeater delay. The AA data that is based on the repeater delayenables a terminal to more finely and stably acquire the GPS satellite signal. Also,accurate and stable acquisition of the GPS satellite signal of the terminal enhances theaccuracy of calculation of the terminal location in the AGPS.
