UMTS/HSPA RAN Performance and Optimization 3 days

CONTENTS:This course provides an end-to-end overview of UMTS/HSPA RAN performance monitoring and optimization. Network

concepts and features are analysed against available network measurements and call traffic signalling flows, to infer the useof different counters and KPIS. Performance KPIs within this course are investigated on a vendor independent perspective,focusing on the concepts and applications. Alongside with the analysis of different KPIs classes and monitoring reports, thiscourse also boosts a comprehensive approach to network troubleshooting and optimization tasks.

PREREQUISITES:General UMTS System knowledge is required. For background knowledge, the Apis course PS Domain Evolution andUMTS Air Interface is recommended. Knowledge of HSPA principles is also essential for this training.

WHO SHOULD ATTEND:This training is best suited for the 3G network planners, optimisers and quality control teams. After attending this course,participants will understand how different KPIs are obtained, infer possible problems within the network and develop efficientapproaches to solve them.
