Positioning Server Reliability Verification for Neighboring Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning methods rely on crowdsourced terminal position information, which is often imprecise, leading to low positioning precision for to-be-positioned terminals.
Innovation Solution
A positioning server obtains and verifies the position information and reliability of neighboring terminals to determine the position of to-be-positioned terminals, improving precision by using RSSI values and reliability verification information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If crowdsourced terminal position information is used for positioning, then positioning coverage is improved, but positioning precision deteriorates
Solution Approach 1:
The patent applies local quality by differentiating between ordinary crowdsourced position data and verified neighboring terminal position data. The system assigns different reliability levels to different data sources, with verified neighboring terminals providing high-precision local position information that complements the broader but less accurate crowdsourced data, thereby resolving the contradiction between coverage and precision.
Solution Approach 2:
The positioning server acts as an intermediary that verifies and validates neighboring terminal position information before using it for positioning. The server mediates between the raw crowdsourced data and the final position calculation, applying verification mechanisms to ensure data reliability while maintaining system-wide positioning coverage.
2Measurement precision
If reliability verification information is collected and processed, then positioning precision is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary verification of neighboring terminal position information before using it for positioning calculations. The positioning server pre-validates the reliability of position data by checking verification information in advance, which simplifies the main positioning process and reduces computational complexity during actual position determination.
Solution Approach 2:
Neighboring terminals self-verify their position information by providing verification data (such as RSSI values, signal strength measurements, or other reliability indicators) that the positioning server can independently validate. This self-service approach reduces the need for complex centralized verification mechanisms while maintaining positioning precision.
