Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing is implemented to serve multiple services with different requirements, then service flexibility and scalability are improved, but network resource management complexity increases
Solution Approach 1:
The patent segments network resources into multiple independent network slices, each dedicated to specific services with different QoS requirements. This segmentation allows flexible resource allocation while simplifying management through dedicated slice controllers that handle each slice independently.
Solution Approach 2:
The patent introduces a QoS parameter transmission mechanism as an intermediary between network slices and service controllers. This intermediary facilitates coordinated resource management across slices without increasing overall system complexity, as the QoS parameters serve as standardized communication interfaces.
2Reliability
If bit rate control is implemented for network slices, then service quality and reliability are improved, but transmission protocol complexity increases
Solution Approach 1:
The patent implements bit rate control by modifying QoS parameters (such as maximum bit rate, minimum bit rate) within existing transmission protocols rather than changing the fundamental protocol structure. This allows reliable service quality control while avoiding unnecessary protocol complexity.
Solution Approach 2:
The patent applies bit rate control selectively to specific network slices that require it, rather than implementing comprehensive control across all traffic. This partial action approach improves reliability for critical services while avoiding the complexity of universal implementation.
3Manufacturing precision
If QoS information transmission is enhanced for network slicing, then service quality assurance is improved, but signaling overhead increases
Solution Approach 1:
The patent transmits QoS parameters in advance during network slice establishment and configuration phases. This preliminary action ensures service quality is pre-configured and enforced, reducing the need for continuous signaling during data transmission and thereby minimizing overhead.
Solution Approach 2:
The patent uses standardized QoS parameter formats that serve multiple functions: slice identification, bit rate control, priority management, and quality verification. This multi-functionality reduces the total signaling overhead compared to separate dedicated signaling for each function.
