Abstract
A method of establishing a search window size for a mobile station in a cellular system is disclosed. For the mobile station searching for a pilot signal of base transceiver station (BTS), the information of maximum index being outputted from the mobile station is gathered, wherein the maximum index is an index number at which the strongest signal is detected within a predetermined window size. For the gathered maximum indexes, confidence level is established and mean value is calculated and then confidence interval is calculated for the gathered maximum indexes using the established confidence level and calculated mean value. A maximum offset of the search window to be applied to the present radio morphology of the cellular system is calculated from the calculated confidence interval and a search window to be applied to the present radio morphology is estimated by increasing the maximum offset by two times. Therefore, the present invention is applicable to the characteristic of the mobile station and radio morphology of the cellular system by estimating the search window using the search result data gathered from the mobile station.
