Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless sensing technology is integrated with communication systems, then sensing services can be provided, but the system complexity increases
Solution Approach 1:
The patent divides the core network into multiple functional entities (Sensing Application Function, Access and Mobility Management Function, Session Management Function) to handle different aspects of sensing service management. This segmentation allows each function to be optimized independently while working together, reducing overall system complexity despite adding sensing capabilities to the communication system.
Solution Approach 2:
The patent enables existing communication infrastructure (core network devices, terminal devices) to perform multiple functions - both traditional communication and sensing services. The sensing capability is integrated into the existing 5G core network architecture, allowing devices to serve dual purposes without requiring completely separate systems, thus managing complexity while achieving versatility.
2Reliability
If terminal devices are selected based on sensing capabilities, then service quality improves, but the selection process complexity increases
Solution Approach 1:
The patent implements preliminary action by having terminal devices register their sensing capabilities with the core network in advance. The Access and Mobility Management Function maintains a database of terminal sensing capabilities, so when a sensing service is needed, the Selection Application Function can quickly query and select appropriate terminals without complex real-time assessment, improving reliability while simplifying the selection process.
Solution Approach 2:
The patent establishes a feedback mechanism where terminal devices provide information about their sensing capabilities to the core network, and the core network responds with service allocation decisions. This feedback loop ensures that terminals with appropriate capabilities are reliably selected for sensing services while the automated feedback process simplifies the selection complexity through standardized capability reporting and processing protocols.
3Productivity
If location information is used for sensing services, then service targeting improves, but information processing complexity increases
Solution Approach 1:
The patent introduces the Access and Mobility Management Function as an intermediary that handles location information processing. This dedicated function receives location data from the Sensing Application Function, processes it to identify appropriate terminals, and returns selection results. By centralizing location processing in a specialized intermediary function, the system achieves efficient service targeting while containing processing complexity within a dedicated module rather than distributing it throughout the entire network.
