Instead, voice communication is transmitted over the

services. To address this, VoNR is implemented, allowing voice calls to be carried over the 5G network using the same
packet-switched infrastructure as other IP-based services, such as video streaming and messaging.
Similar to how
VoLTE enables voice calls on 4G networks, VoNR serves as the 5G equivalent for voice communication, but it requires a
5G standalone (SA) network to function. VoNR offers better voice quality than its 4G predecessor, primarily due to the inherent
lower latency of
5G NR
5G NR (5G New Radio) is a radio access technology (RAT) developed by the 3rd Generation Partnership Project (3GPP) for the 5G (fifth generation) mobile network. It was designed to be the global standard for the air interface of 5G networks. It is ...
, allowing for faster call setup and improved overall communication.
Additionally, VoNR removes the LTE anchor, enabling the voice call to stay entirely within the 5G network.
VoNR calls are generally charged at the same rate as other calls, and to make a VoNR call, the device, its firmware, and the mobile telephone provider must all support the service and work together in the specific area.
