5.5G Core Unleashes the Vast Potential of Calling

At the 5G Core Summit 2022 held by Informa Tech and co-hosted by Huawei in Bangkok, Thailand, George Gao, President of Huawei CS and IMS Domain, delivered a speech titled From Voice to Video and Content, 5.5G Core Unleashes the Vast Potential of Calling. He elaborated on the strategies and evolution involving the 5.5G-oriented voice network, from voice to video and then to content, which further consisted of minute-level operation to content operation. He emphasised the values and profits on mobile phone screen content, not just the call duration. George said that the 5.5G-oriented voice network further unleashes the vast potential of calling, and helps operators achieve commercial success.

The VoLTE penetration rate is greater than 80 percent and suitable for the withdrawal of 2G and 3G networks.

VoLTE is fundamental in the 5G era, and all current 5G operators have already constructed VoLTE networks.

To avoid multi-network operation, improve spectral efficiency, and gain more business benefits, hundreds of operators plan to shut down the 2G and 3G networks from 2022 to 2025. In this process, VoLTE is indispensable.

According to this process, both 2G and 3G traffic will be migrated to VoLTE networks, preventing any potential fallbacks on such antiquated networks. According to the estimation of operator M in Asia Pacific, 50 percent of its traffic is carried on 3G networks. However, if the 3G networks are disabled and VoLTE is not deployed, more than 6000 2G sites need to be added to carry the traffic. This is unacceptable. Therefore, this operator plans to increase the VoLTE penetration rate from 30 percent to 80 percent within two years, laying a solid foundation for exiting the 3G network.

Calling services form the most important and basic core services for operators, with indispensable and unique business and social values. A seamless calling experience is critical to the reputation and user loyalty of operators.

Voice calling is gradually evolving to video calling, delivering a greater variety of content during calls. More and more users are willing to pay for personalised content. The VoLTE-based video RBT service has been developed to enable users to express themselves and deliver enterprise content, which has achieved a positive business cycle within the China markets.

At present, some leading operators are vigorously developing VoLTE/VoNR-based video calling. With higher quality, faster connections, data-free, and ease of use, video calling becomes more and more popular and can be quickly developed as a basic service.
