Solution Overview
Problem
Not all WLAN devices are equipped with the necessary hardware and software capabilities for WLAN sensing, limiting their ability to provide richer services due to device price and cost constraints.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If WLAN sensing capability is added to all devices, then sensing service capability is improved, but device cost and complexity increase
Solution Approach 1:
The patent introduces an intermediary mechanism where a sensing-capable device (acting as mediator) provides sensing services to non-sensing-capable devices through frame-based communication. The sensing service request frame, response frame, and report frame enable the intermediary device to perform sensing operations on behalf of other devices, allowing NSCS devices to access sensing functionality without possessing the actual sensing hardware or software capabilities.
Solution Approach 2:
The patent implements a copying mechanism where the sensing capability is replicated across the network through software coordination rather than physical hardware duplication. The sensing-capable device copies its sensing processing capabilities to serve multiple non-sensing devices, allowing NSCS devices to obtain sensing services without duplicating the expensive sensing hardware in each device.
2Adaptability or versatility
If WLAN sensing capability is added to all devices, then sensing service provision is improved, but device price increases
Solution Approach 1:
The patent implements universality by enabling a single sensing-capable device to serve multiple non-sensing-capable devices simultaneously. The intermediary device performs multiple sensing operations for different clients using the same hardware and software resources, making the sensing capability universally accessible across the network without requiring each device to have dedicated sensing hardware, thereby reducing per-device cost.
Solution Approach 2:
The sensing service capability is copied through software implementation rather than hardware duplication. The patent allows NSCS devices to access sensing functionality by receiving processed sensing results from SCS devices, effectively copying the sensing service capability across the network without replicating the underlying hardware costs in each device.
3Adaptability or versatility
If sensing service request and coordination mechanisms are implemented, then service coverage is improved, but communication overhead increases
Solution Approach 1:
The patent extracts the sensing processing function from individual devices and centralizes it in sensing-capable devices. By taking out the complex sensing computation from NSCS devices and concentrating it in SCS devices, the system reduces communication overhead - only lightweight request frames, response frames, and result reports need to be exchanged, rather than transmitting raw sensing data or complex processing instructions between all devices.

AI summary
The disclosure relates to the technical field of WLAN (wireless local area network) communications, and specifically to a method and apparatus for providing a WLAN sensing service, a terminal device, and a storage medium. The method is applied to a terminal device, and the terminal device includes a terminal device NSCS without a WLAN sensing capability. The method includes steps of: sending a sensing service request frame to a terminal device SCS with a WLAN sensing capability, the sensing service request frame including a sensing service identifier (Sensing SID); receiving a sensing service response frame sent by the SCS, the sensing service response frame including a Status code and a Sensing SID, and the Status code indicates that the SCS agrees or disagrees to provide a sensing service; and receiving a sensing result acquired when the SCS performs a WLAN sensing progress.
