WCDMA Counters and Key Performance Indicators

   

Bestell-Nr.:

TA-TC 6270

   

Dauer:

4 days / web session 4x4 hours

   

Zielgruppe:

Personnel from performance monitoring and optimization / troubleshooting department.

   

Zielsetzung:

This course provides guidance on how to monitor the performance of the WCDMA network, especially the UTRAN. Important KPIs are introduced to evaluate accessibility, retainability and mobility procedures as well as the performance of the air interface and the quality of service experienced by the user. Practical sections present the evaluation of 3GPP failure causes and of the air interface performance based on call trace and OSS data.
