Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in verifying the authenticity of location information, particularly in V2X communication scenarios, where manipulation or forgery of location data can compromise safety-related services.
Innovation Solution
A method and apparatus for requesting and verifying satellite information using satellite identifiers to confirm the accuracy of location information, involving the transmission of request messages based on configuration information for sidelink or uplink signals, and determining the number of satellite identifiers needed based on the distance between location information discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite information is requested for location verification, then verification reliability is improved, but data size and signaling overhead increase
Solution Approach 1:
The patent applies partial action by requesting only the necessary number of satellite identifiers based on the distance threshold. When the distance between location information and reference location exceeds the threshold, the system requests satellite information for verification. This selective approach ensures verification reliability is improved only when needed, avoiding unnecessary data transmission and reducing overall data size while maintaining adequate verification coverage.
2Measurement precision
If satellite identifiers are requested for location verification, then verification accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent implements dynamics by making the number of requested satellite identifiers variable rather than fixed. The system dynamically determines the number of satellite identifiers to request based on the calculated distance between the received location information and the reference location. This dynamic adjustment optimizes signaling overhead by requesting more satellite identifiers only when the distance exceeds the threshold, thereby maintaining verification accuracy while minimizing unnecessary signaling.
3Reliability
If location information verification is performed, then safety service reliability is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing a distance threshold before verification is needed. The system pre-configures the threshold value that will be used to determine when satellite information should be requested. This preliminary setup enables rapid verification decisions without requiring complex real-time calculations, thus improving safety service reliability through consistent verification criteria while reducing processing time by avoiding unnecessary verification steps when the threshold is not exceeded.
