商品描述

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.

商品描述(中文翻譯)

Voice over LTE (Long Term Evolution)介紹了在4G移動網絡中用於傳輸包含語音數據和電話信令的IP數據包以及用於在IMS(IP多媒體子系統)網絡中提供電話服務的技術。儘管將4G網絡切換到2G/3G網絡存在困難,但電話通信不會在4G網絡上建立。本書分析了已經部署的技術,例如CSFB(Circuit Service FallBack),這是一種臨時解決方案,使連接到4G網絡的手機可以接收由2G/3G網絡傳輸的警報。本書還介紹了基於4G網絡傳輸的電話信令所依賴的SIP(Session Information Protocol),提供服務並定義路由的IMS網絡,維持通信的SRVCC(Single Radio Voice Call Continuity)機制以及提供補充服務的TAS(Telephony Application Server)。
