In collaboration with Intel, SK Telecom (SKT) has successfully developed technology to reduce communication delays necessary for the evolution of 6G Core Network Architecture. The Core network is the gateway through which all voice and data traffic generated from a customer’s mobile device passes through to access the Internet network. It is a mobile communication service system that is responsible for security and service quality through the inter-connection of various systems.
Editor’s NOTE: Of course, 6G is currently undefined with only the features and functions being defined by ITU-R WP 5D which is meeting this week in Geneva. The 6G core network specifications will be done by 3GPP and NOT ITU-T as was the case for 5G core.
The 6G Core Architecture is required to have higher flexibility and safety than previous generations of wireless communications, and to provide stable AI service quality and technologies to customers by embedding intelligent and automation technologies.
As Core network technology continues to develop, the various systems that make up the network and the detailed functions that provide various services are also explosively increasing. As network complexity continues to increase, the process of sending and receiving messages is frequently recreated. Therefore, communication delays will increase compared to before. It is difficult to address these limitations with communication standard technologies (service communication proxies) for interconnection between unit functions within the existing Core network.
Inline Service Mesh, a low latency technology the two companies developed utilizing Intel Xeon processors with built in AI, is capable of increasing the communication speed within the Core network by reducing latency between unit function without Proxy.
Through this technology development, AI, which requires a large amount of computation, can be applied to the Core network in a wider variety of models. SKT has already commercialized a technology that reduces wireless resources by 40% and improves connectivity by analyzing movement patterns of real users in real time. Through this cooperation, the two companies will be able to reduce communication delays by 70% and increase service efficiency by 33% in the Core network through the application of the 6G Core Architecture.
SKT aims to apply the results of this study to commercial equipment next year. A technical white paper has been published by Intel that describes the technology, development process and benefits.
SKT and Intel have been continuing to cooperate for research on the development of key wired/wireless mobile communication technologies for the past 10 years. Based on the results of this study, the two companies plan to continue research and development for traffic processing improvement technologies incorporating AI technology in various areas of the Core network.
“We have made another technical achievement through continuous technology development cooperation with Intel to secure leadership in 6G,” said Yu Takki, Vice President and Head of Infra Tech at SKT. “We will continue our research and make efforts to commercialize AI-based 6G Core Architecture.”
“Our research and development efforts with SK Telecom continue to deliver innovations that have been deployed by Communications Service Providers worldwide”, said Dan Rodriguez, Corporate Vice President of Intel Network & Edge Solutions Group. “By leveraging the latest Intel Xeon processors with built in AI features, our companies are able to drive both performance and efficiency improvements that will be vital to the future Core networks.
Last March, SKT and NTT DOCOMO released a white paper addressing the requirements for future 6G networks.
The South Korean carrier said the new white paper contains its views on 6G key requirements and 6G evolution methodology, along with its opinions on the latest trends in frequency standardization. The 6G white paper also provides analysis, development directions and methodologies pertaining to promising 6G use cases, technology trends as well as and candidate frequencies.
The 6G White Paper reviews the following:
- Performance requirements and implementation scenarios for each frequency band, taking into account the characteristics of each frequency
- Issues concerning coverage and devices in high-frequency bands
- Standardization for migration to 6G architecture and application of cloud-native / open architecture
