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.
GlobalData, a leading information services company, and Huawei jointly released The 5G Voice Transition: Managing the Complexity. The white paper describes the current challenges facing operators who run voice networks over multiple generations, and proposes building a convergent voice network that would solve transition issues. It also points out that the high-value services supported by the IP Multimedia Subsystem (IMS) data channel are the new development direction for voice.
GlobalData has released its 2024 edition of the IMS and Voice Core: Competitive Landscape Assessment report. It recognizes Huawei's Single Voice Core (SVC) as the sole leader in the market, achieving a perfect score in all dimensions — a first in the report's history. This achievement highlights the exceptional competitiveness and market performance of the SVC solution.
Andy Hicks, Senior Principal Analyst at GlobalData, said that 5G-oriented continuous evolution requires 2G through 5G networks to be converged into one. He believed that this convergence would improve user experiences, simplify roaming solutions, and promote the development of New Calling to bring more business opportunities for operators.
