Voice over LTE (Long Term Evolution) presents the mechanisms putin place in 4G mobile networks for the transportation of IP packetscontaining voice data and telephone signaling, as well as thetechnologies used to provide a telephone service in the IMS (IPMultimedia Sub-system) network.
Despite the difficulty connected to the handover of the 4G networkto the 2G/3G network, a telephone communication will not beestablished on the 4G network. This book analyzes the technologiesthat have been put in place, such as CSFB (Circuit ServiceFallBack), an interim solution that enables a mobile connected tothe 4G network to receive an alert transmitted by the 2G/3Gnetwork.
The book also goes on to develop the SIP (Session InformationProtocol) on which the telephone signaling transferred by the 4Gnetwork is based, the IMS network that provides the service anddefines the routing, the SRVCC (Single Radio Voice Call Continuity)mechanism that maintains communication and the TAS (TelephonyApplication Server) that supplies supplementary services.
