Engineering Contradiction Analysis
1Productivity
If sensing measurement data is transmitted between sensing function network element and sensing device network element, then sensing service can be provided, but transmission and processing overheads increase
Solution Approach 1:
The patent applies preliminary action by having the sensing device network element perform sensing measurements and generate measurement data locally before any network transmission occurs. The device autonomously determines sensing results from raw measurements, so that only essential result information needs to be transmitted to the sensing function network element, significantly reducing data transmission volume and processing overheads in the network.
Solution Approach 2:
The patent extracts only the essential sensing result information from the complete sensing measurement data. Instead of transmitting all raw measurement data through the network, the system extracts and transmits only the critical outcome information that the sensing function network element needs, thereby reducing network overheads while maintaining sensing service functionality.
2Adaptability or versatility
If extensive signaling interaction is performed between sensing function network element and sensing device network element, then sensing service coordination is achieved, but signaling overheads increase
Solution Approach 1:
The patent applies self-service by enabling the sensing device network element to autonomously perform sensing measurements, process measurement data, and determine sensing results without requiring extensive signaling coordination with the sensing function network element. The device independently completes the sensing task and reports only the final result, eliminating the need for continuous signaling interaction for data collection and processing coordination.
Solution Approach 2:
The sensing device network element performs sensing measurements and data processing in advance before network interaction is needed. By completing the sensing operation locally first and then reporting results, the system minimizes the frequency and volume of signaling interactions required for service coordination.
3Measurement precision
If sensing function network element processes large amount of sensing measurement data, then accurate sensing results are obtained, but processing overheads and latency increase
Solution Approach 1:
The patent extracts the essential sensing result determination function from the network element and places it at the sensing device network element. The device locally processes measurement data and extracts only the necessary result information, eliminating the need for the sensing function network element to process large volumes of raw measurement data, thereby reducing processing overheads and latency while maintaining result accuracy.
Solution Approach 2:
The sensing device network element performs measurement data processing and result determination in advance before network transmission. By completing data processing locally first, the system avoids network-induced latency and reduces the processing burden on the sensing function network element, achieving both speed and accuracy.
