METHOD AND ARRANGEMENT FOR MEASURING AND PREDICTING OF RADIOCONDITIONS IN A COMMUNICATIONS SYSTEM

摘要

In a mobile telecommunication system the transmission quality is dependent o n a wide range of radio conditions. The method solves the problem associated wit h extracting a useful estimation of the radio environment of a mobile station in communication in order to predict how the radio conditions will change for t he considered mobile station in the near future. A measurement report (210) is sent from the mobile station to its serving base station. The quality measured 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 ar e classified (260). Classified data are grouped (270) resulting in the final map, which i s stored in a database (280). The final map may be used to enhance the performance of radi o network algorithms.
