Abstract:
A method of detecting a position of a mobile station in a wireless radiocommunication system including said mobile station, a plurality of base stations and a control station, said method comprising:a step in which each of said base stations measures reception radio strength levels of a radio wave emitted from said mobile station which stands at a measuring point, and communicates the measurement results to said control station;a step in which said control station learns, through a neural network, a correlation between said reception radio strength levels and a position of said mobile station on the basis of said measurement results at a plurality of measuring points and position data of said measuring points;a step in which each of said base stations measures reception radio strength levels of a radio wave transmitted from said mobile station which stands at an arbitrary point and conveys the measurement results to said control station; anda step in which said control station estimates a position of said mobile station producing said measurement results, on the basis of the correlation between reception radio strength levels and a position of said mobile station obtained through the learning.
