An introduction to LTE / Christopher Cox

Public ISBD Titre : An introduction to LTE : LTE, LTE-Advanced, SAE, VoLTE and 4G Mobile Communications Type de document : texte imprimé Auteurs : Christopher Cox, Auteur Editeur : Willey Année de publication : 2014 Importance : 449 p Format : 25 x 17.5 cm ISBN/ISSN/EAN : 978-1-118-81803-9 Langues : Français (fre) Langues originales : Français (fre) Mots-clés : LTE, LTE-Advanced, SAE, VoLTE and 4G Mobile Communications Index. décimale : 621 Physique appliquée Résumé : Following on from the successful first edition (March 2012), this book gives a clear explanation of what LTE does and how it works. The content is expressed at a systems level, offering readers the opportunity to grasp the key factors that make LTE the hot topic amongst vendors and operators across the globe. The book assumes no more than a basic knowledge of mobile telecommunication systems, and the reader is not expected to have any previous knowledge of the complex mathematical operations that underpin LTE. This second edition introduces new material for the current state of the industry, such as the new features of LTE in Releases 11 and 12, notably coordinated multipoint transmission and proximity services; the main short- and long-term solutions for LTE voice calls, namely circuit switched fallback and the IP multimedia subsystem; and the evolution and current state of the LTE market. It also extends some of the material from the first edition, such as inter-operation with other technologies such as GSM, UMTS, wireless local area networks and cdma2000; additional features of LTE Advanced, notably heterogeneous networks and traffic offloading; data transport in the evolved packet core; coverage and capacity estimation for LTE; and a more rigorous treatment of modulation, demodulation and OFDMA. The author breaks down the system into logical blocks, by initially introducing the architecture of LTE, explaining the techniques used for radio transmission and reception and the overall operation of the system, and concluding with more specialized topics such as LTE voice calls and the later releases of the specifications. This methodical approach enables readers to move on to tackle the specifications and the more advanced texts with confidence.

Voice Over LTE / André Pérez

Public ISBD Titre : Voice Over LTE : EPS and IMS Networks Type de document : texte imprimé Auteurs : André Pérez, Auteur Editeur : Willey Année de publication : 2013 Importance : 230 p Format : 24 x 16 cm ISBN/ISSN/EAN : 978-1-84821-534-4 Langues : Anglais (eng) Langues originales : Français (fre) Mots-clés : Voice Over, LTE,EPS,IMS Networks. Index. décimale : 621 Physique appliquée Résumé : 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. Note de contenu : 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.
