Huawei's Single Voice Core solution was awarded the "Best 5G Voice Solution" and "Communications Innovator of the Year" at the Voice & Advanced Communications Summit held in Berlin, in November 2019. These awards highlight Huawei’s innovation of real-time communications technologies, and network evolution and application.
Voice remains a fundamental telecom service in 5G. As in 3GPP specifications, 5G mobile voice services can be implemented through voice over NR (VoNR) on the IMS, and EPS fallback to the LTE network (VoLTE) rather than fallback to 2G/3G is recommended. Moreover, traditional CS services will be able to exist for significantly longer. The coexistence of different radio access technologies (2G, 3G, 4G, and 5G) will make voice network O&M more complex and service experience inconsistent. Multi-network convergence and simplification are key.
Huawei's innovative Single Voice Core solution makes the voice network easier to use and addresses these problems. This solution converges multiple voice networks and allows all types of subscribers (2G/3G/4G/5G/fixed-line) to access an all-in-one voice network. This reduces the numbers of NEs and peripheral interfaces, optimizes resource sharing within NEs, and ensures a consistent service experience. The solution further reduces operating expense (OPEX), increases return on investment (ROI), and improves O&M efficiency. The solution accelerates the phasing out of CS networks and the full cloudification of voice networks, enabling a quick innovation of industry applications through network capability openness.
"It is a great honor to win the awards for the Huawei Single Voice Core solution. Thank you for your recognition", said Zhao Yue, president of CS&IMS Product Line of Huawei Cloud Core Network. Huawei will help carriers build an all-in-one 5G voice infrastructure network, and will open network capabilities to enable 20 billion, real-time audio and video connections between people, and between people and things, in the industry, creating further value for customers".
Owing to its constant investment in voice services, Huawei now has mature voice solutions and extensive experience. Huawei's VoLTE solution has been used commercially by more than 70 carriers worldwide, serving more than 600 million subscribers.
