The training presents standard R8-R12 E-UTRAN counters and KPIs that are comparable across all vendors' implementations. Each counter is described in the system-wide context of procedures and configuration parameters impacting its value.

Please note that only standard counters and KPIs are covered. This training should not be considered as an alternative to similarly titled trainings offered by equipment vendors, since standard counters are just a small fraction of the total number of counters available in real equipment. The counters covered in this training can, however, be used for benchmarking of E-UTRAN areas served by eNBs from different manufacturers.

Target audience:

This training is an excellent choice for engineers and managers who have already been familiar with LTE™/EPS and require knowledge about the most fundamental E-UTRAN counters and KPIs that should be available in every vendor implementation. This knowledge can be a basis for further self or instructor lead studies on E-UTRAN performance management. At the same time it should be sufficient for engineers who are not directly responsible for E-UTRAN but for some reason need an overview of E-UTRAN measurements (e.g. EPC/CN, IMS/VoLTE/RCS engineers).

Duration:

1 day.
