VoLTE vs ViLTE
VoLTE stands for voice over Long Term Evolution. Utilising IMS technology, it is a digital packet voice service that is delivered over IP via an LTE access network.Voice calls over LTE are recognised as the industry-agreed progression of voice services across mobile networks, deploying LTE radio access technology.
ViLTE stands for video over LTE. It’s an extension of VoLTE, which enhances voice services with a high quality video channel.ViLTE is a conversational – that is person-to-person – video service, which is based on the IP Multimedia Subsystem (IMS) core network. It has specific profiles for the control and media planes of the video service. Conversational video is also possible via EPC-integrated Wi-Fi – see VoWi-Fi.In order to deploy ViLTE, Voice over LTE (VoLTE) is required. It’s advisable to combine ViLTE with RCS to provide the best service offering for consumers.
