Kurs Titel:

LTE Counters and Key Performance Indicators

   

Bestell-Nr.:

TA-TC 6470

   

Dauer:

4 days / web session 4x4 hours

   

Zielgruppe:

Engineers working in E-UTRAN performance and QoS monitoring and field engineering.

   

Zielsetzung:

This course provides guidance on how to monitor the performance of the LTE radio access network. Important KPIs based on 3GPP are introduced to evaluate accessibility, retainability and mobility procedures as well as the traffic and the performance of the air interface and the quality of service experienced by the user. Specific services and enhanced features like VoLTE, carrier aggregation and SON are included. Use cases present the evaluation of 3GPP failure causes and of the air interface performance based on OSS data.
