Contact Tracking Server Using Wireless Signal Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack an efficient way to identify and track asymptomatic carriers of infectious diseases, particularly in public places where the risk of transmission is high due to the virus's airborne and surface survival, and the difficulty in tracing contacts of individuals who may not show symptoms.
Innovation Solution
A contact tracking method and server system that utilizes wireless signals from user equipment to determine positioning information, record travel routes, and analyze contact situations based on signal strength, geolocation, and mobility data to identify potential asymptomatic carriers by comparing the travel routes of individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large-scale testing is conducted to identify asymptomatic carriers, then the identification capability improves, but the cost and time consumption increase significantly
Solution Approach 1:
The system performs preliminary tracking of travel routes and contact situations before asymptomatic carriers cause widespread infection. By continuously recording positioning information and analyzing travel routes in advance, the system can quickly identify potential carriers when needed, avoiding the need for time-consuming large-scale testing at later stages.
Solution Approach 2:
The patent introduces wireless signal positioning information and travel route analysis as an intermediary mechanism between asymptomatic carriers and identification. Instead of directly testing everyone, the system uses location data and contact tracing as a mediator to efficiently narrow down potential carriers, reducing both time and resource requirements.
2Object-affected harmful factors
If contact tracking is implemented to identify potential carriers, then the transmission risk reduces, but the system complexity increases
Solution Approach 1:
The system uses universal wireless positioning technology that leverages existing cellular network infrastructure. The same wireless signal technology used for general mobile communication is repurposed for contact tracking, avoiding the need for specialized complex tracking devices and reducing overall system complexity.
Solution Approach 2:
User equipment automatically records its own positioning information and travel routes without requiring complex external tracking infrastructure. The system leverages the device's own capabilities (wireless signals, positioning functions) to self-track, minimizing the complexity of external tracking systems.
3Productivity
If wireless signal positioning is used to track multiple persons, then the tracking efficiency improves, but the privacy concerns increase
Solution Approach 1:
The system extracts only the necessary minimal information for contact tracing - specifically positioning information and travel route data - rather than collecting comprehensive personal information. By taking out only what is needed for tracking efficiency while leaving other personal data aside, the system balances productivity with privacy protection.
Data Source
AI summary
A contact tracking method and a related server are provided. In the method, the positioning information of multiple user equipments (UEs) is obtained. The UEs transmit wireless signals. The positioning information is determined based on the wireless signal. The wireless signal indicates a network provider identifier, a signal strength, or geolocation. The travel routes of the UEs are determined. Each travel route records the positioning information of one UE over time. The travel routes are analyzed to determine a contact situation between a first UE and a second UE of the UEs based on a contact criteria.
