Solution Overview

Problem

Current WLAN technologies lack the ability to diversify user needs and are dependent on terminal movement, failing to dynamically detect changes in terminal location and status, such as unauthorized movement or accidents, and provide optimal connection switching.

Innovation Solution

A method and device that acquire location information of a terminal, determine motion action parameters, and match them with a pre-constructed action pattern model to sense changes in terminal location and status in real-time, enabling dynamic detection of terminal motion and providing optimal connection switching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional WLAN connection establishment is used, then basic wireless communication is achieved, but the system cannot detect terminal motion or status changes

Engineering Contradiction:
Improveterminal status detection capabilityVSAvoidfunctionality diversity
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The Access Point is enhanced to perform multiple functions: traditional wireless communication establishment plus motion detection and status monitoring. By acquiring location information from terminals and analyzing movement patterns, the AP becomes a multi-functional device that simultaneously provides connectivity and security monitoring capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Location information serves as an intermediary element between the terminal and the detection system. The AP acquires location data from terminals and uses this intermediate information to infer motion status and detect anomalies, enabling indirect detection without requiring additional sensors on the terminal.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If connection handover between APs is implemented, then terminal mobility is supported, but the system cannot detect unauthorized movement or accidents

Engineering Contradiction:
Improveunauthorized movement detectionVSAvoiddetection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses existing location information that terminals naturally provide during normal operation for connection management. This self-service approach allows the AP to detect motion and unauthorized movement using data already being collected for routing and handover purposes, without requiring additional complex detection infrastructure.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors location information and provides feedback about terminal motion status. By comparing location data over time, the AP can detect anomalies such as unauthorized movement or accidental drops, creating a closed-loop monitoring system that enhances security while using existing communication infrastructure.

Inventive Principle:
Principle #23Feedback

3Reliability

If real-time location monitoring is performed, then terminal motion detection is achieved, but energy consumption increases

Engineering Contradiction:
Improvereal-time detection accuracyVSAvoidterminal energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Location information is acquired and processed in advance during normal communication operations. The system prepares location data for potential motion detection analysis before anomalies occur, allowing real-time detection without requiring continuous high-energy processing or additional terminal battery consumption for dedicated monitoring functions.

Inventive Principle:
Principle #10Preliminary action
