Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Radio Access Technologies (RATs) have limitations in positioning accuracy and are primarily suited for outdoor use, failing to meet the requirements for precision and coverage in indoor scenarios.
Innovation Solution
A positioning method and device that acquire and combine positioning information from multiple RATs, such as LTE, WLAN, and others, to determine the position of a terminal with improved accuracy, enabling joint positioning across various RATs and applicable in indoor environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional single RAT positioning is used, then the positioning method is simple, but the positioning accuracy is insufficient and cannot meet indoor scenario requirements
Solution Approach 1:
The patent combines positioning information from multiple RATs (LTE, WLAN, Bluetooth, etc.) into a unified positioning framework. The terminal acquires positioning data from different radio access technologies and integrates them through a positioning server to determine the final position, thereby improving accuracy while managing complexity through systematic integration
2Adaptability or versatility
If traditional RAT positioning is used, then the implementation is straightforward, but the positioning coverage is limited to outdoor wide spaces
Solution Approach 1:
The patent creates a universal positioning system that can operate across multiple scenarios (outdoor and indoor) by supporting multiple RATs. The system adapts to different environments by selecting and combining appropriate positioning methods from available RATs, making the positioning functionality versatile across diverse deployment scenarios
3Measurement precision
If multiple RATs are used for joint positioning, then the positioning accuracy improves, but the system complexity increases
Solution Approach 1:
The patent introduces a positioning server as an intermediary that manages the complexity of multi-RAT positioning. The terminal interacts with the server, which coordinates the acquisition of positioning information from multiple RATs, processes the data, and determines the final position. This intermediary architecture improves positioning accuracy while centralizing the complexity management
