Herramienta de diagnosis para redes móviles basada en puntos sigmas de correlaciones

Abstract

Mobile network users are demanding with regard to the quality of the services, forcing the operators to solve the network degradations in the shortest time possible. For this purpose, a method for root cause diagnosis of degradations is proposed. It is based on different correlations (among CMs and a KPI) and the weighted average of sigma points to provide a ranking of possible causal candidates. Finally, this method is tested on metrics obtained from a commercial equipment.
