6G native intelligence network architecture enabled by intent abstraction and knowledge.

6G will evolve to an intelligent network, featured by native intelligence and openness. The study of standardization of intelligent network emphasizes the importance of intent-driven network for network intelligence. However, current intent-based networking takes the intent as "What to do" rather than "What you want". Moreover, current knowledge defined network (KDN) can partially fulfill "How to configure the network" according to "What to do". Therefore, a 6G native intelligent network architecture based on the intent abstraction and knowledge was proposed, aiming to achieve "How to configure the network" according to "What you want". Firstly, an intent abstraction module was designed to obtain "What to do" from "What you want", composed of intent acquisition, intent translation, intent mapping, and intent modeling. Secondly, the cognitive module was proposed to achieve "How to configure the network" according to "What to do", which got network knowledge through joint optimization of machine learning and logical reasoning. Finally, enabling key technologies such as intent mapping, network information measurement, network policy generation, and network policy verification were introduced to support the implementation of 6G native intelligence.
