Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless sensing technologies face high overheads in data transmission and processing due to large amounts of sensing measurement data and signaling interaction between network elements, which is inefficient and resource-intensive.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensing measurement data is transmitted between network elements to execute sensing detection service, then sensing service can be provided, but data transmission overheads increase
Solution Approach 1:
The patent combines multiple sensing services into a single sensing task execution. The network element determines that one sensing task can satisfy multiple sensing service requirements simultaneously, thereby consolidating data transmission and processing operations. This merging approach reduces redundant signaling interaction and data transmission overhead while maintaining reliable sensing service provision.
2Reliability
If sensing measurement data is processed by sensing function network element, then sensing results can be obtained, but processing overheads increase
Solution Approach 1:
The patent extracts and utilizes existing sensing measurement data that has already been collected by sensing device network elements for multiple sensing services. Instead of processing separate data streams for each service, the system extracts a common data set that can satisfy multiple service requirements, thereby reducing processing overhead while maintaining result accuracy.
3Adaptability or versatility
If signaling interaction is performed between sensing function network element and sensing device network element, then sensing service can be coordinated, but signaling overheads increase
Solution Approach 1:
The patent implements a multi-functional sensing task design where a single sensing task configured by the sensing function network element can serve multiple sensing services simultaneously. This universal approach allows one sensing task to fulfill diverse service requirements (such as positioning, speed measurement, distance measurement) without requiring separate signaling interactions for each service, thereby reducing signaling overhead while maintaining coordination flexibility.
