Download or read book UMTS Performance Measurement written by Ralf Kreher and published by John Wiley & Sons. This book was released on 2006-07-11 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 data Contains 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 lab Explains measurement limitations and how tolerances provide valuable information for validation and evaluation of measurement results Provides 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.

Book excerpt: UMTS (Universal Mobile Telecommunication System) ist die dritte Generation von Telekommunikationssystemen und beruht auf der Funkschnittstelle WCDMA (Wideband Code Division Multiple Access). WCDMA bietet im Vergleich zu CDMA Vorteile durch die Nutzung eines breiteren Übertragungsbandes, eine hohe Übertragungsrate (maximal 2 Mbit/s) sowie eine gesteigerte Systemkapazität und Kommunikationsqualität durch statistisches Multiplexing. UMTS macht Dienste für die Benutzer von mobilen Computern und Mobiltelefonen unabhängig von ihrem Standort zugänglich und ermöglicht innovative Dienste (zum Beispiel pay-per-bit, pay-per-session, flat rate, asymmetric bandwidth, Video Conferencing, Virtual Home Environment und andere). Dieser Band führt Sie in zellulare Netze und die digitale Kommunikation ein. Behandelt werden die Funkschnittstelle, der Funkzugang und das Basisnetzwerk. Gut verständlich werden die 99er Spezifikation erklärt sowie UMTS-Dienste und zukünftige Dienste, die über 3G hinausgehen, vorgestellt. Viele Übungsaufgaben, teils mit Lösungen, erleichtern das Vertiefen des Stoffes.

Download or read book Optimization and Performance Analysis of High Speed Mobile Access Networks written by Thushara Weerawardane and published by Springer Science & Business Media. This book was released on 2012-01-07 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and development of cost-effective mobile broadband wireless access networks is a key challenge for many mobile network operators. The over-dimensioning or under-dimensioning of an access network results in both additional costs and customer dissatisfaction. Thushara Weerawardane introduces new transport technologies and features for High Speed Packet Access (HSPA) and Long-Term Evolution (LTE) networks. Using advanced scientific methods, he proposes new adaptive flow control and enhanced congestion control algorithms, then defends them with highly-developed analytical models derived from Markov chains. For faster analysis, compared to long-lasting detailed simulations, these models provide optimum network performance and ensure reliable quality standards for end users during transport network congestion. Further, the author investigates and analyzes LTE transport network performance by introducing novel traffic differentiation models and buffer management techniques during intra-LTE handovers.

Download or read book Switching to VoIP written by Theodore Wallingford and published by "O'Reilly Media, Inc.". This book was released on 2005 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it's revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP. VoIP has advanced Internet-based telephony to a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowersbusinesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm. Developed from real-world experience by a senior developer, O'Reilly's Switching to VoIP provides solutions for the most common VoIP migration challenges. So if you're a network professional who is migrating from a traditional telephony system to a modern, feature-rich network, this book is a must-have. You'lldiscover the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems impact network infrastructure, as well as solutions for common challenges involved with IP voice migrations. Among the challenges discussed and projects presented: building a softPBX configuring IP phones ensuring quality of service scalability standards-compliance topological considerations coordinating a complete system ?switchover? migrating applications like voicemail and directoryservices retro-interfacing to traditional telephony supporting mobile users security and survivability dealing with the challenges of NAT To help you grasp the core principles at work, Switching to VoIP uses a combination of strategy and hands-on how-to that introduce VoIP routers and media gateways, various makes of IP telephone equipment, legacy analog phones, IPTables and Linux firewalls, and the Asterisk open source PBX software by Digium.You'll learn how to build an IP-based or legacy-compatible phone system and voicemail system complete with e-mail integration while becoming familiar with VoIP protocols and devices. Switching to VoIP remains vendor-neutral and advocates standards, not brands. Some of the standards explored include: SIP H.323, SCCP, and IAX Voice codecs 802.3af Type of Service, IP precedence, DiffServ, and RSVP 802.1a/b/g WLAN If VoIP has your attention, like so many others, then Switching to VoIP will help you build your own system, install it, and begin making calls. It's the only thing left between you and a modern telecom network.
