Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If base station functions are separated into central unit and distributed unit, then flexibility and customization for various services are improved, but intercompatibility between units from different manufacturers deteriorates
Solution Approach 1:
The patent applies universality by defining a standardized fronthaul interface that enables the central unit and distributed unit to communicate through common protocols and data structures. This standardization allows different manufacturers' equipment to interoperate, ensuring that the separated architecture maintains reliability while achieving flexibility through customizable network function configurations.
2Adaptability or versatility
If base station functions are separated into central unit and distributed unit, then customized service provision for each location is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the base station into central unit and distributed unit with clearly defined functional boundaries. The central unit handles higher-layer protocols and control functions, while the distributed unit manages radio frequency operations. This segmentation enables customized service provision through flexible configuration of network functions in each unit, while the standardized fronthaul interface simplifies the overall system architecture by providing clear separation of concerns.
3Adaptability or versatility
If various types of base stations are dynamically configured, then service customization is improved, but configuration management difficulty increases
Solution Approach 1:
The patent applies parameter changes by enabling dynamic configuration of network functions through modification of configuration parameters and data structures transmitted over the fronthaul interface. The standardized interface allows flexible adjustment of service parameters while maintaining consistent management procedures, thus improving service customization without proportionally increasing configuration management difficulty.
