Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DetNet technology is integrated with 5G systems to provide deterministic networking services, then time-deterministic service capability is improved, but system complexity increases due to interface and protocol integration requirements
Solution Approach 1:
The patent introduces a session management function (SMF) as an intermediary component that mediates between DetNet controllers and 5G network elements. The SMF translates DetNet configuration parameters into 5G data model parameters, acting as a bridge that enables integration without requiring direct complex interactions between DetNet and 5G systems. This intermediary approach resolves the contradiction by maintaining reliability through proper parameter mapping while managing system complexity through centralized translation functionality.
Solution Approach 2:
The patent implements parameter mapping and transformation mechanisms that convert DetNet configuration parameters into equivalent 5G data model parameters. By changing the parameter representation and semantics to match the target system's data model, the patent enables seamless integration while abstracting away the complexity of cross-system parameter compatibility. This parameter transformation approach allows deterministic networking services to be provided without exposing the underlying integration complexity to end systems.
2Adaptability or versatility
If DetNet configuration parameters are mapped to 5G data model, then interoperability between DetNet and 5G systems is improved, but information loss may occur during parameter transformation
Solution Approach 1:
The patent implements feedback mechanisms where the session management function verifies parameter mapping results and can request additional information or clarification when parameter transformations may result in information loss. The system monitors the mapping process and provides feedback loops that ensure critical DetNet parameters are properly preserved in the 5G data model representation. This feedback approach maintains interoperability while preventing information loss by validating transformations and requesting missing information when needed.
3Reliability
If interface and protocol for DetNet traffic control messages are established, then service capability for time-sensitive applications is improved, but implementation difficulty increases
Solution Approach 1:
The patent designs the session management function to perform multiple roles: it acts as a DetNet interface, a parameter translator, a configuration manager, and a coordination hub. By consolidating these multiple functions into a single universal component, the patent reduces implementation difficulty compared to creating separate dedicated systems for each function. The multi-functional SMF simplifies deployment while maintaining full service capability for time-sensitive applications through its integrated approach to DetNet-5G integration.
