Single Voice Core

With 5G, operators can still use 4G voice architecture and deeply converge the control and media planes to provide real-time voice and video services. Huawei created the fully cloudified and converged Single Voice Core to help operators converge their five voice networks into one. This enables the IMS voice network to process CS, VoLTE, and Vo5G mobile voice services, as well as PSTN and NGN fixed voice services, which accelerates VoLTE subscriber migration and sets the foundation for further innovation.
