Sidelink Positioning Authorization for Privacy-Protected Location Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in ensuring privacy protection for location information sharing during sidelink positioning, particularly when terminals are out of network coverage, leading to potential exposure of sensitive information.
Innovation Solution
Implementing a first rule to determine whether a positioning service is allowed, enabling privacy policies to be executed both in network coverage and out of coverage, thereby preventing the exposure of privacy information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location information is shared during sidelink positioning, then positioning accuracy is improved, but privacy security deteriorates
Solution Approach 1:
The patent segments the location information sharing process into multiple controlled stages: discovery phase, selection phase, and positioning phase. Each stage has specific authorization checks and privacy policies that must be satisfied before proceeding. This segmentation allows the system to share only the minimum necessary information at each stage rather than all location data, thus improving positioning accuracy while protecting privacy.
Solution Approach 2:
The patent introduces an intermediary authorization mechanism that mediates between the need for location sharing and privacy protection. This intermediary layer verifies authorization rules, checks privacy policies, and controls information flow between terminals. The intermediary ensures that location information is shared only when proper authorization is obtained, resolving the contradiction between positioning accuracy and privacy security.
2Object-affected harmful factors
If privacy policies are enforced for positioning services, then privacy security is improved, but communication complexity increases
Solution Approach 1:
The patent implements preliminary authorization checks and privacy policy configurations before the actual positioning service begins. During the discovery and selection phases, terminals pre-establish authorization rules and privacy preferences. This preliminary action ensures that when positioning occurs, the complexity of privacy enforcement is already resolved, reducing real-time communication complexity while maintaining strong privacy protection.
Solution Approach 2:
The patent changes the parameter of authorization verification from a continuous complex process to a discrete set of predefined authorization rules and privacy policy parameters. By parameterizing the privacy enforcement mechanism with configurable rules and policies, the system reduces communication complexity while maintaining effective privacy protection through structured parameter validation rather than complex continuous negotiation.

AI summary
The present disclosure relates to a sidelink communication method, apparatus and device, and a storage medium. The method comprises: on the basis of a first rule, determining that a positioning service is allowed to be executed with a second terminal, wherein the second terminal is used for providing the positioning service, and the first rule is used for indicating whether the positioning service is allowed to be executed with the second terminal; and sending first information, wherein the first information is used for instructing the second terminal to execute the positioning service. By means of a first rule, it is determined that a corresponding positioning service is allowed to be executed with a second terminal, such that a privacy policy for the positioning service can be executed with network coverage and/or without network coverage, thereby preventing some terminals in need of privacy protection from exposing corresponding privacy information, and thus improving security during communication.
