UMTS Performance Measurement - Guide to KPI for UTRAN

The radio technology behind UMTS is seen in two different varieties: Frequency duplex division (FDD also known as WCDMA) where uplink and downlink data is transmitted on two different frequency bands; and time division duplex (TDD), where uplink and downlink channels are separated using timeslots. TDD is beyond the scope of this book.


Performance measurement represents a new stage of monitoring data.In the past monitoring networks means decoding messages and filtering which messages belong to the same call.Performance measurement is an effective means of scanning the whole network at any time and systematically searching for errors, bottlenecks and suspicions behaviors.
