Abstract
A method of identifying a position of a user equipment within a wireless communication network includes: a) providing expected radio signal strengths produced by at least one radio communication station on each of plural elementary area elements in which a geographic area is subdivided; b) defining an initial attenuation experienced by the radio signals to the user equipment whose position is to be identified; c) obtaining measured radio signal strength measurements of the radio signals provided to the user equipment whose position is to be identified; d) determining an estimated elementary area element corresponding to the position of the user equipment whose position is to be identified based on the expected radio signal strengths, the initial attenuation and the radio signal strength measurements, and e) computing a final attenuation based on the estimated elementary area element. The operations b)-e) are iterated at least twice.
