This extensively updated second edition of LTE Signaling, Troubleshooting and Performance Measurement describes the LTE signaling protocols and procedures for the third generation of mobile communications and beyond. It is one of the few books available that explain the LTE signaling messages, procedures and measurements down to the bit & byte level, and all trace examples are taken for a real lab and field trial traces. This book covers the crucial key performance indicators (KPI) to be measured during field trials and deployment phase of new LTE networks. It describes how statistic values can be aggregated and evaluated, and how the network can be optimized during the first stages of deployment, using dedicated examples to enhance understanding. Written by experts in the field of mobile communications, this book systematically describes the most recent LTE signaling procedures, explaining how to identify and troubleshoot abnormal network behavior and common failure causes, as well as describing the normal signaling procedures. This is a unique feature of the book, allowing readers to understand the root cause analysis of problems related to signaling procedures. This book will be especially useful for network operators and equipment manufacturers; engineers; technicians; network planners; developers; researchers; designers; testing personnel and project managers; consulting and training companies; standardization bodies.

This completely revised and updated edition of the highly successful UMTS Signaling provides a deep insight into all aspects of UMTS signalling. The chapter structure has been reworked for improved “usability” for readers, as well as including many new features and updates. The successful trial, deployment, operation and troubleshooting of 3G or UMTS infrastructures and applications is the biggest challenge facing today’s mobile communications. Network element instability, network element and multi-vendor interoperability, configuration and network planning faults are just a few of the challenges affecting performance and profitability that need to be addressed. This book is an invaluable guide to resolving such problems. Highlights of the Second Edition: Includes new information and scenarios on HSPA / HSDPA / HSUPA, and IMSCovers not only WCDMA, but also TD-SCDMA issuesContains up-to-date information on releases 5 and 6, and includes a new chapter on the future releases 7 and 8Provides crucial information for network operators and equipment suppliers keen to understand how to handle and analyse UMTS signaling procedures in order to get the network into operation, detect errors and troubleshoot faultsUses first hand, real world information to explain issues which are unclear in the standardsIncludes comprehensive descriptions and documentation of UMTS reference scenarios for different UMTS procedures The unified comprehensive approach taken by the authors makes this book essential reading for engineers in network operators, integrators or system suppliers who need to be at the cutting edge of this technology. It will also be an invaluable resource for postgraduates on telecommunications courses, especially those with a focus on signal analysis.

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. Includes clear coverage of the fundamentals of performance measurement software architecture and ways to collect and present statistical dataContains numerous call flow diagrams, conversion tables, protocol message examples and sample measurement results that can be used as reference for daily work in the field or labExplains measurement limitations and how tolerances provide valuable information for validation and evaluation of measurement resultsProvides an overview of how performance measurement software works as well as information on how data streams are captured and analyzed, and how analysis results are aggregated and presented in graphic user interfaces and reports Providing a gateway into the world of UMTS-specific measurement scenarios and a general overview of what can be defined and measured at an in-depth technical level, this book will appeal to those involved in network operation, planning, configuration and deployment, as well as consulting and training companies, students, technical journalists and measurement equipment manufacturers.
