Solution Overview
Problem
Existing cellular networks, particularly those based on 4G and 5G-New Radio, are inadequate in efficiently handling and sharing sensing measurements, limiting the integration of sensing capabilities within communication services.
Innovation Solution
A method for selecting the most suitable device for a sensing procedure involves receiving criteria, assigning devices based on geographic area and time duration, checking for criteria fulfillment, computing an objective function, and sending a request to the selected device to perform the sensing procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular networks integrate sensing capabilities with communication services, then sensing measurements can be collected and processed, but the network becomes more complex in handling and sharing sensing measurements
Solution Approach 1:
The patent segments the device selection process into distinct phases: initial filtering based on geographic area and time duration criteria, followed by evaluation using an objective function. This segmentation reduces network complexity by breaking down the complex sensing measurement handling into manageable steps, where each phase addresses specific aspects of device selection independently.
Solution Approach 2:
The patent applies preliminary action by pre-filtering devices based on geographic area and time duration criteria before conducting the full objective function evaluation. This preliminary filtering step reduces the number of devices that need to be fully evaluated, thereby reducing network complexity while maintaining the ability to integrate diverse sensing capabilities.
2Measurement precision
If all devices in a group are evaluated for sensing procedures, then the most suitable device can be selected, but the time and computational resources required increase
Solution Approach 1:
The evaluation process is segmented into two stages: initial filtering based on geographic area and time duration criteria, followed by objective function evaluation only for devices that pass the filter. This segmentation maintains measurement precision by ensuring thorough evaluation of qualified devices while reducing selection time by excluding non-qualified devices from detailed evaluation.
Solution Approach 2:
The patent applies partial action by evaluating only a subset of devices (those meeting geographic and time criteria) with the full objective function, rather than evaluating all devices in the group. This reduces selection time and computational resources while maintaining selection accuracy for the most suitable device among qualified candidates.
3Reliability
If devices that do not meet criteria are included in evaluation, then no suitable device might be missed, but computational resources are wasted on non-compliant devices
Solution Approach 1:
The patent applies preliminary action by filtering devices based on geographic area and time duration criteria before conducting the full objective function evaluation. This preliminary filtering ensures that only potentially suitable devices undergo computationally intensive evaluation, reducing energy consumption while maintaining reliability by ensuring all qualified devices are considered.
Solution Approach 2:
The patent extracts and eliminates non-compliant devices from the evaluation pool before performing the full objective function evaluation. This extraction of non-qualified devices reduces computational energy consumption by focusing resources only on devices that meet the basic geographic and time criteria, while maintaining reliability through systematic filtering.
