Server Positioning Method Using Multi-Parameter Measurement Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular mobile communication positioning methods, such as CID, suffer from low precision due to reliance on base station IDs alone, lacking comprehensive measurement parameters for accurate UE positioning.
Innovation Solution
A positioning method involving a server that determines and sends measurement configuration information to a terminal, including parameters like PMI/RI, handover failure rate, and signal-to-interference-plus-noise ratio, for the terminal to measure and respond with positioning response parameters, enabling improved positioning accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If CID positioning method is used with base station ID only, then positioning simplicity is maintained, but positioning precision deteriorates
Solution Approach 1:
The positioning measurement parameter is segmented into multiple independent components including PMI/RI characteristics, handover failure rate, radio link failure rate, signal to interference plus noise ratio, and number of interfering cells. Each component is measured and reported separately to enable comprehensive positioning analysis while maintaining systematic organization
Solution Approach 2:
Multiple previously separate measurement parameters (PMI, RI, handover failure rate, radio link failure rate, signal quality metrics) are merged into a unified positioning measurement parameter framework. This combination enables the server to perform integrated analysis for improved positioning precision while maintaining ease of operation through standardized reporting procedures
2Measurement precision
If multiple measurement parameters are collected for positioning, then positioning precision is improved, but system complexity increases
Solution Approach 1:
The positioning measurement parameter framework is designed with multi-functionality to serve various positioning scenarios. The same set of measurement parameters (PMI, RI, handover failure rate, radio link failure rate, signal quality) can be universally applied across different network conditions and terminal types, reducing the need for scenario-specific parameter sets and thereby managing system complexity
Solution Approach 2:
The terminal autonomously measures and reports all necessary positioning parameters (PMI, RI, handover failure rate, radio link failure rate, signal quality metrics) without requiring complex external coordination. The server simply receives and processes these self-reported measurements, significantly reducing system complexity while maintaining high positioning precision
