CTOnews.com, November 24, 2022 Global 6G Development Conference opened recently. With the theme of "drawing Vision together, working together", the conference focuses on the vision of 6G. Nokia Bell Labs delivered a keynote speech on "6G, seeing the Future". Centering on the key trend of 6G as a bridge to connect the physical world, the biological world and the digital world, it is clear that 6G is a powerful force in the future meta-universe. At the same time, based on the in-depth analysis of the values, design principles, requirements and challenges of 6G, this paper also expounds the innovation of 6G network architecture and key enabling technologies, and emphasizes the importance of 6G joint innovation.

First of all, 6G will be a powerful force for the future meta-universe, supporting various potential application scenarios of the meta-universe, including the consumer meta-universe, the enterprise meta-universe with information interconnection technology as the core, and the industrial meta-universe with industry operation technology as the core. In fact, the core lies in two points: how to enhance human beings themselves, and how to better control the physical world around us through the integration of the digital world and the physical world.

In order to help the future meta-cosmic era, 6G puts forward corresponding requirements in terms of technical design principles.

Sustainability: mainly to increase energy consumption per unit of bit, that is, to improve energy efficiency and minimize carbon emissions.

Digital inclusiveness: 6G needs to ensure full coverage, which cannot be accomplished only by traditional land communication systems, and requires organic integration of ground, air, space, and even water communication systems to ensure 6G signals. Can reach every corner of the earth.

Security and privacy: this is particularly important for 6G systems. The reason lies in many aspects: a large number of equipment access, the wide application of artificial intelligence technology, a variety of open interfaces, and so on, all provide opportunities for potential data interception. The existence of various hybrid clouds, open sources, devices from different manufacturers, and so on, will bring potential security risks.

From the perspective of 6G network architecture, the future 6G system is a network with highly cognitive, automated, specialized and customized characteristics.

The entire network architecture can be considered in terms of three layers:

The first layer is the infrastructure layer. The concept of implementing various network functions on the cloud platform will continue and be strengthened.

The second layer is the network function layer. According to the different requirements of different application scenarios, different network capabilities are provided to meet the KPI requirements of various applications, such as transmission delay, reliability and so on.

The third layer is the application layer. Based on the needs of their respective business, under the arrangement of management and choreography functions, the corresponding data transmission and processing tasks are realized with the help of network infrastructure layer and function layer.

Finally, there is the management and choreography function. According to the KPI requirements of different applications, this network function can not only achieve efficient management, but also make use of various infrastructure and network functions to complete the corresponding data transmission.

CTOnews.com learned that Nokia said it would solve the challenges facing 6G through six key technological innovations, including new spectrum technology, AI-based air port technology, synaesthesia integration technology, extreme network and technology to ensure network security and reliability. Nokia calls on the industry to do more research on the prime band of 7~20GHz to tap its potential and promote its potential application in the 6G era.
