UMTS RF Troubleshooting Guideline

[lamhd_bk]

The UMTS RF Troubleshooting Guideline is the base document for the UMTS
optimisation process and is used for the identification, classification and
resolution of problems, failures or performance degradations that might be
observed during the optimisation activity.
This document covers the following items:
• Drive test data analysis (Uu traces and 2G/3G scanner measurements)
• Network interface tracing analysis (e.g. Iu, Iur and Iub interface tracing)
• PM KPI analysis
• End-to-end performance analysis
Furthermore this guideline is cross correlating the observed occurrences to the
corresponding UTRAN parameter, PM counters and KPIs of the UTRAN and/or
CN and gives references.
Last but not least this document is used as a specification for writing queries
that automatically identify and classify failures and problems from network
interface traces and drive test data.
