Utilization of advanced analysis methods in UMTS networks

The scope of this paper is to introduce new analysis and visualization methods for WCDMA cellular networks. The proposed examples are mainly based on the self-organizing map (SOM) method, but also other neural and statistical methods are equally applicable. The main motivation for advanced methods is to increase the abstraction level from the raw network measurements, i.e. radio access network language, to network functional areas or a language closer to the business of network operator. Furthermore the vast amount of quality of service (QoS) and service combinations, that 3G will enable, require effective data handling procedures.
