This 3-day course provides knowledge about key performance indicators (KPIs) for 3G radio access networks. It will cover the formulas for deriving KPIs and include signaling scenarios to understand their effects on performance management counters and KPIs. The training is intended for 3G network planners, optimizers, and quality control teams who need to monitor network performance during deployment. A background in UMTS systems and HSPA principles is recommended. The course will cover topics such as KPI hierarchies, field measurement KPIs, accessibility, retainability, mobility, capacity and quality KPIs.

UMTS and HSPA RAN KPI – 3 days
CONTENTS:
The content of this course provide the knowledge to derive the formulae for Key Performance Indicators of 3G Radio Access Network. KPI knowledge cannot be achieved unless the signalling is understood in detail. Therefore, this course will also include the call flows, handover and many other signalling scenarios. Instead of digging into each parameter signalled with a message, this course emphasises on the effect of signalling messages on the performance management counters and KPIs.
WHO SHOULD ATTEND:
KPI knowledge is required to monitor the network performance at various stages of deployment. KPI monitoring is a never ending task of network operation and maintenance. Therefore, this training is best suited for the 3G network planners, optimisers and quality Control team. KPIs are also used in benchmarking. After going through this training, we will be able to validate whether the formulae defined by vendor and 3rd party tools are realistic or not.
PREREQUISITES:
General UMTS System knowledge is required. For background knowledge, the Apis course PS Domain Evolution and UMTS Air Interface is recommended. Knowledge of HSPA principles is also essential for this training.
