Huawei recently released the Vo5G (Voice over 5G) Technical White Paper. Based on the development of Vo5G standard and the voice and video codec standard,Huawei has analysed Vo5G evolution solutions in different 5G networks and specified directions for 5G voice evolution. It also points out that deploying the IMS and accelerating the commercial use of VoLTE are the only way to move towards Vo5G.

As the standardisation of 5G at the first stage has been successfully completed, 5G networks will be put into commercial use. In addition to the expansion of 5G network coverage and maturity of the terminal ecosystem, carriers need to consider the factors of various 5G network deployment options when deploying 5G networks.

The white paper points out that the 5G voice solution will face many options, such as VoNR, VoeLTE, EPS FB, and RAT FB. For the industry, Vo5G is needed to collectively define all 5G voice solutions.

According to the white paper, Vo5G has been standardised with the standard process of 3GPP 5G, and Vo5G must be provided based on IMS. VoLTE will become the basic voice network in the 5G era and work with Vo5G to ensure the continuity of voice services. Therefore, deploying the IMS and accelerating the commercial use of VoLTE is the only way to move towards Vo5G.

With the advent of 5G, the services and network architecture will continuously evolve to catch up with the new real-time communication market with 20 billion connections and also inherit 7 billion connections. The entire industry needs to plan future-oriented real-time communications networks in advance to continuously evolve to the next-generation communications networks.
