Method for measuring and predicting of radio conditions in communications system

In a mobile telecommunication system the transmission quality is dependent on a wide range of radio conditions. A method for extracting a useful estimation of the radio environment of a mobile station in communication in order to predict how the radio conditions will change in the near future for a considered mobile station in the near future. A measurement report is sent from the mobile station to the base station. The quality measure in the measurement report is filtered over the area by a smoothing filter (220), and then processed through an updating filter (230) resulting in a time varying map (240). Several maps are classified (260). Classified data are grouped (270) resulting in the final map, which is stored in a database (280). The final map may be used to enhance the performance of radio network algorithms.
