Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service-based architecture with selective protocol implementation is implemented, then adaptability to support multiple wireless devices and technologies is improved, but device and network complexity increases
Solution Approach 1:
The network architecture is segmented into multiple user plane functions (UPFs) that can be selectively implemented based on traffic requirements. Each UPF handles specific protocol requirements, allowing the network to support multiple wireless devices and technologies without requiring all functions to be present in every network element. This segmentation enables flexible adaptation while managing complexity through modular deployment.
Solution Approach 2:
The service-based architecture implements dynamic protocol selection where UPFs are activated or deactivated based on real-time traffic conditions, device capabilities, and service requirements. This dynamic configuration allows the network to adapt its complexity level according to actual needs, supporting multiple technologies only when and where required rather than maintaining fixed complex structures throughout.
2Productivity
If selective protocol implementation based on traffic conditions is implemented, then productivity and traffic management efficiency are improved, but measurement and control difficulty increases
Solution Approach 1:
The network implements feedback mechanisms that continuously monitor traffic conditions, device capabilities, and service requirements to dynamically determine which UPFs should be activated. This feedback loop enables automatic protocol selection based on real-time measurements of traffic load, packet sizes, and device types, improving traffic management efficiency while reducing the difficulty of control through automated decision-making based on measured parameters.
Solution Approach 2:
The system changes operational parameters such as UPF activation states, protocol selection, and resource allocation based on measured traffic conditions. By dynamically adjusting these parameters according to observed traffic patterns, device capabilities, and service requirements, the network achieves efficient traffic management while the parameter-based control framework simplifies the measurement and control process compared to fixed complex rule sets.
