What Does Voice Over Long-Term Evolution (VoLTE) Mean?
Voice over long-term evolution (Voice over LTE/VoLTE) is a technology specification that defines the standards and procedures for delivering voice communication and data over 4G LTE networks. It is one method for creating, provisioning and managing high-speed voice, video and messaging services on a 4G wireless network for mobile and portable devices.
Techopedia Explains Voice Over Long-Term Evolution (VoLTE)
VoLTE primarily works on IP-based networks and only supports packet switching. The data received from a circuit-switched cellular network such as the Global System for Mobile Communications (GSM) or a Code Division Multiple Access (CDMA) network will be converted into network packets before being broadcast. VoLTE uses IP multimedia subsystem (IMS) based networks to offer these services. It will not work on networks that are not compatible with or that have not integrated IMS within their core architecture. The services that can be provisioned using VoLTE include video calling, voice calling, and multimedia streaming and sharing services.
