Abstract
VoLTE is an IP multimedia subsystem (IMS)-based voice solution defined by 3rd Generation Partnership Project (3GPP). It inherits traditional voice services and SMS, as well as integrating voice services with a wide variety of FMC service. This approach results in the voice service (control and media planes) being delivered as data flows within the LTE data bearer. This means that there is no dependency on (or ultimately, requirement for) the legacy circuit-switched voice network to be maintained. VoLTE has up to three times more voice and data capacity than 3G UMTS and up to six times more than 2G GSM. Furthermore, it frees up bandwidth because VoLTE’s packetsheaders are smaller than those of unoptimized VoIP/LTE
