Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to provide accurate positioning information for potential future positions of terminals, particularly in environments where satellite coverage is absent, leading to suboptimal route planning and operational inefficiencies in autonomous vehicles.
Innovation Solution
A system that provides positioning accuracy information for potential future positions of terminals by integrating sector-based positioning accuracy data collection and distribution within cellular networks, allowing terminals to request and receive updates on expected accuracy levels and methods for future locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite-based positioning is used for terminals, then positioning accuracy is improved in open environments, but positioning accuracy deteriorates in environments without satellite coverage such as indoor areas
Solution Approach 1:
The patent segments the positioning system into multiple independent positioning methods (satellite-based positioning and cellular network-based positioning) that can operate independently or in combination. The network determines positioning accuracy separately for each method and provides this segmented information to the terminal, allowing the terminal to adaptively select or combine methods based on environmental conditions.
Solution Approach 2:
The patent changes the parameter being provided from raw positioning coordinates to positioning accuracy information. By providing accuracy metrics rather than just position data, the system enables terminals to make informed decisions about route planning and positioning method selection based on expected accuracy levels in different environments.
2Device complexity
If terminals use satellite positioning without knowing future accuracy levels, then device complexity is reduced, but route planning quality deteriorates due to lack of predictive information
Solution Approach 1:
The network performs preliminary calculation and determination of positioning accuracy for potential future positions along a route before the terminal actually reaches those positions. This advance provision of accuracy information allows the terminal to perform better route planning without increasing its own computational complexity.
Solution Approach 2:
The cellular network acts as an intermediary that calculates and provides positioning accuracy information between the positioning infrastructure and the terminal. This intermediary role allows the terminal to benefit from accurate predictive information without needing to implement complex calculation algorithms itself.
3Loss of information
If the network provides detailed positioning accuracy information for all potential future positions, then route planning quality is improved, but network signaling overhead increases
Solution Approach 1:
The patent applies local quality by providing positioning accuracy information selectively for specific locations along the route rather than uniformly for all potential positions. The network determines and provides accuracy information for positions that are relevant to the terminal's route planning needs, optimizing the balance between information completeness and signaling overhead.
