Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different encapsulation modes are used for TDM and packet services, then service compatibility is improved, but scheduling uniformity deteriorates
Solution Approach 1:
The patent introduces a unified data structure called radio data unit (RDU) that homogenizes the representation of both TDM and packet services. By using a common encapsulation format with standardized fields for service identification, priority, and length, the system achieves scheduling uniformity while maintaining support for multiple service types. The RDU structure eliminates the need for separate handling mechanisms for different service types.
2Productivity
If priority-based scheduling is implemented, then bandwidth allocation efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-assigning priority levels and service types to each radio data unit during the encapsulation phase. Priority information is embedded in the RDU header before transmission, enabling receiving nodes to perform simple priority-based scheduling without complex real-time analysis. This pre-processing approach simplifies the scheduling decision-making process at each node.
Solution Approach 2:
The patent segments the bandwidth allocation process into discrete priority levels, where each priority class is handled independently through dedicated transmission queues. This segmentation transforms a complex continuous optimization problem into a series of simpler discrete decisions, reducing computational complexity while maintaining allocation efficiency.
3Productivity
If uniform data structure is adopted, then scheduling capability is improved, but service-specific optimization is reduced
Solution Approach 1:
The radio data unit structure is designed with multi-functionality to serve both TDM and packet services within a single unified framework. The RDU contains flexible fields that can accommodate different service types through service identification indicators, while maintaining a consistent overall structure. This universal design enables both broad scheduling capability and service-specific optimization through the use of standardized yet adaptable fields.
