1. 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 said mobile station measures reception radio strength levels from said plurality of base stations at a measuring point to communicate the measurement results through one of said base stations 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 positional data of said measuring points and conveys parameters of said neural network, obtained through the learning, to said mobile station; and

    a step in which said mobile station constructs a neural network using said parameters to detect its own position on the basis of reception radio strength levels from said plurality of base stations measured at an arbitrary point through the use of the constructed neural network.
