Sidelink Ranging Privacy Control for 5G UE Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ranging/SL positioning services in 5G networks do not consider the privacy issues of user equipment (UEs), posing a security risk during ranging operations.
Innovation Solution
Implement a ranging method that determines service parameters based on a privacy profile of user equipment (UE) associated with a ranging request, using a location network function to control and verify UE ranging operations via a sidelink, ensuring compliance with privacy requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ranging operations are performed via sidelink in 5G networks, then positioning accuracy and service functionality are improved, but privacy security and user data protection deteriorate
Solution Approach 1:
The patent introduces a location network function as an intermediary between UEs performing sidelink ranging. This mediator verifies privacy profiles and controls ranging operations, allowing positioning accuracy to be maintained while privacy security risks are mitigated through centralized verification and authorization mechanisms.
Solution Approach 2:
The patent implements feedback mechanisms where the location network function continuously monitors ranging operations against privacy profiles. The system provides feedback control by allowing or blocking ranging requests based on verified privacy compliance, thus maintaining both positioning functionality and privacy security dynamically.
2Object-affected harmful factors
If privacy verification and control mechanisms are implemented in ranging operations, then privacy security is improved, but system complexity and operational overhead increase
Solution Approach 1:
The location network function is designed to perform multiple functions including privacy profile verification, ranging authorization, and operation monitoring within a single centralized entity. This multi-functionality approach consolidates complexity into one component rather than distributing it across multiple elements, thereby improving privacy security without proportionally increasing overall system complexity.
