Abstract:

This paper first introduces the architecture and function of the current definition of 5G user plane. Combined with the new service demand scenarios of 5G-A and 6G in the future, the driving force of user plane evolution is analyzed. Then, it reviews the research progress of user plane and its enhancement technology in the standard groups. Finally, it identifies and analyzes the key evolution trend of the user plane in the future, including deep integration with the edge, centralized and distributed collaboration, customization, and open sharing, etc., and provides a reference for further promoting the evolution of the user plane and helping the network to empower thousands of industries and industries.

Key words: user plane, distributed network, 6G, endogenous intelligence, integration of computing and network
