La voix sur LTE : Réseau 4G et architecture IMS available in PDF, EPUB and Kindle. La voix sur LTE (Long Term Evolution) présente les mécanismes mis en oeuvre dans le réseau de mobiles 4G pour le transport de paquets IP contenant la voix et la signalisation téléphonique, ainsi que les technologies utilisées pour la fourniture du service téléphonique dans le réseau IMS (IP Multimedia Sub-system). Malgré la difficulté liée au handover du réseau 4G vers le réseau 2G/3G, l’établissement d’une communication téléphonique ne sera pas réalisé sur un réseau 4G. Cet ouvrage analyse les technologies mises en oeuvre, comme le CSFB, solution d’attente qui permet à un mobile attaché au réseau 4G de recevoir une alerte (paging) transmise par le réseau 2G/3G. Le protocole SIP sur lequel se base la signalisation téléphonique transférée par le réseau 4G, le réseau IMS qui fournit le service et définit le routage, le mécanisme SRVCC qui assure le maintien de la communication et le serveur d’applications TAS, sont également développés. L’auteur Consultant et formateur en réseaux et télécommunications, intervient auprès des industriels et des opérateurs sur des études d’architecture. Il anime des formations sur les réseaux 4G et IMS pour NEXCOM.

This book was released on 2013-09-03. Voice over LTE available in PDF, EPUB and Kindle. Voice over LTE (Long Term Evolution) presents the mechanisms put in place in 4G mobile networks for the transportation of IP packets containing voice data and telephone signaling, as well as the technologies used to provide a telephone service in the IMS (IP Multimedia Sub-system) network. Despite the difficulty connected to the handover of the 4G network to the 2G/3G network, a telephone communication will not be established on the 4G network. This book analyzes the technologies that have been put in place, such as CSFB (Circuit Service FallBack), an interim solution that enables a mobile connected to the 4G network to receive an alert transmitted by the 2G/3G network. The book also goes on to develop the SIP (Session Information Protocol) on which the telephone signaling transferred by the 4G network is based, the IMS network that provides the service and defines the routing, the SRVCC (Single Radio Voice Call Continuity) mechanism that maintains communication and the TAS (Telephony Application Server) that supplies supplementary services. Contents 1. The EPS Network. 2. The LTE Interface. 3. The CSFB Function. 4. SIP and SDP Protocols. 5. The IMS Network. 6. Telephone Services. 7. The SRVCC Function. About the Authors André Perez is a consultant and teacher in networks and telecommunications. He works with industrialists and operators regarding architecture studies and leads training on the 4G and IMS networks for NEXCOM.

Download and read online ebook Voice over LTE write by Miikka Poikselkä. This book was released on 2012-03-05. Voice over LTE available in PDF, EPUB and Kindle. Describes the technological solutions and standards which will enable the migration of voice and SMS services over to LTE/EPC networks Main drivers for the introduction of Long Term Evolution of UTRAN (LTE) is to provide far better end user experience for mobile broadband services. However, service providers also need to have a clear strategy of how to offer voice and messaging services for consumers and enterprises. The voice service over LTE is becoming increasingly important when the smartphone penetration is increasing rapidly. Smartphones require both good quality voice and high speed broadband data. This book provides the exhaustive view to industry-approved technologies and standards behind the Voice over LTE (VoLTE). Whether a decision maker or technology analyst, this book explains a topic of substantial global market interest. It provides a good introduction to the technology and is useful for operators who may be deploying VoLTE, product managers responsible for VoLTE products and those who work in implementation and standardization of related technologies. Provides a comprehensive overview of industry-approved technologies and standards, providing vital information for decision makers and those working on the technology Written by authors working at the cutting edge of mobile communications technology today, bringing a mix of standards and product background, guaranteeing in-depth practical and standards information Covering the technical and practical elements of VoLTE, explaining the various approaches for providing voice services over LTE

Assessing the Migration from CS Voice to IMS-based Voice over LTE (VoLTE) available in PDF, EPUB and Kindle. Master's Thesis from the year 2016 in the subject Computer Science - Miscellaneous, grade: 1,0, University of Applied Sciences Technikum Vienna (Telecommunications and Internet Technologies), language: English, abstract: Operator-provided voice services will gradually migrate from today’s circuit-switched (CS) voice networks to packet-switched IP networks, using Voice over LTE (VoLTE) as the foundation to provide telecom-grade telephony services. In fact, the capability of transporting Voice over IP (VoIP) services along with the provision of high-rate data throughputs, characterizes one of the critical drivers for the LTE development. This thesis presents the first implications of introducing IMS-based VoLTE in Germany, Austria and Switzerland (DACH) from a mobile operator’s perspective. Further VoLTE performance aspects such as parameter optimization and HD voice are discussed, thus serving as a basis to then analyze the DACH mobile network test results for 2014 in terms of telephony and data performance. Overall results for a DACH VoLTE trial conducted in the third quarter 2014 complement the analysis.
