Abstract

The present invention concerns a method for determining a map of an area associated to a base station, the map being composed of probability distributions associated to coefficients, the terminal receiving signals from the base station or the base station receiving signals from the terminal. The method comprises the steps of: - determining an initial map which is modeled by a random field, - obtaining measurements on power of signals transferred between the base station and the terminal and positioning measurements, -obtaining probability distributions associated to coefficients of the map which correspond to the power measurements, - determining the probability distributions of the location, - checking if the variance of the determined probability distributions is upper than a given value, - updating the map if the variance of the determined probability distributions of the location is lower than the given value.
