Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5GS serves as a TSN bridge to provide deterministic services, then transmission reliability is improved, but device complexity increases due to the need to determine egress window information
Solution Approach 1:
The patent applies preliminary action by pre-calculating and determining the egress window information based on the ingress window information and transmission delay characteristics before data packet transmission. This allows the 5GS to prepare the egress timing parameters in advance, ensuring deterministic service delivery without adding complex real-time decision-making mechanisms during packet forwarding.
2Manufacturing precision
If egress window information is determined to ensure deterministic service delivery, then transmission precision is improved, but loss of time increases due to the additional processing steps
Solution Approach 1:
The egress window information is determined in advance using pre-configured transmission delay characteristics and ingress window parameters. This preliminary determination eliminates the need for complex real-time calculations during packet forwarding, thus achieving precise egress timing control without significant time loss.
3Reliability
If 5GS determines egress window information for TSN service data packets, then transmission characteristics are ensured, but device complexity increases due to additional acquisition and calculation processes
Solution Approach 1:
The 5GS determines the egress window information autonomously by utilizing its own stored transmission delay characteristics and the received ingress window information. This self-service mechanism eliminates the need for external control entities or complex inter-device coordination, thereby ensuring transmission characteristics while minimizing the increase in device complexity.
