作者简介：Ralf Kreher works as a Senior Software Architect for Tektronix’ Mobile Protocol Test (MPT) business with a focus on UMTS Performance Measurement and Key Performance Indicator (KPI) implementation. Before joining the engineering department he led the MPT Customer Training Department for almost four years, being responsible for a world-class seminar portfolio for mobile technologies and measurement products. Kreher holds a Communication Engineering Degree of the University of Applied Science, Deutsche Telekom Leipzig and is the author of the book "UMTS Signaling" (2005, John Wiley & Sons, Ltd.). Ralf Kreher currently resides in Germany.

内容简介

UMTS Performance Measurement is a practical guide that explains how to identify and measure the main problems seen in today's UMTS live networks and will make performance measurement results gathered in the UTRAN environment understandable for the reader. It provides a fundamental background for daily work in the field or lab, covering a wide range of performance measurements that help to troubleshoot and optimize the UTRAN environment.

The content goes far beyond what has been defined by international standard bodies like 3GPP and closes the gap between international standards and definitions of network equipment manufacturers (NEM) and network operators. The emphasis is on definition of Key Performance Indicators (KPIs) and measurements that are not described in 3GPP standard documents, such as throughput measurements and the success/failure analysis of all possible handover types.
