Engineering Contradiction Analysis
1Speed
If core network functions are deployed in a conventional mobile communication network, then subscriber management and control functions can be provided, but processing delays occur and efficiency and rapidity are insufficient for 6G requirements
Solution Approach 1:
The core network functions are segmented into control plane functions (C-plane) and user plane functions (U-plane). The C-plane functions are deployed in the first communication network, while the U-plane functions are deployed in the communication device. This segmentation allows parallel processing of control and user data, eliminating sequential processing delays and improving overall speed for 6G requirements.
2Productivity
If more access points are deployed to realize higher frequency and wider bandwidth radio communications, then communication capacity increases, but network complexity and deployment difficulty increase
Solution Approach 1:
The communication device is designed to perform multiple functions: it acts as an access point for radio communication, a router for data forwarding, and provides core network user plane functions. This multi-functionality reduces the need for separate dedicated devices, simplifying network deployment while maintaining high communication capacity through increased access points.
3Productivity
If control plane function and user plane function are separated and deployed in different networks, then efficiency and rapidity improve, but device complexity increases
Solution Approach 1:
The communication device merges multiple functions including access point operations, routing capabilities, and core network user plane functions into a single integrated unit. While the control plane remains separate in the first communication network, the merging of multiple functions in the communication device simplifies overall deployment and reduces the complexity of managing separate specialized devices for each function.
