Radio Map Quality Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio-based positioning systems face challenges in controlling access to quality information for radio maps, particularly in preventing bad faith users from obtaining accurate positioning data, which can lead to sabotage or misuse of the radio map, and in ensuring that only reliable contributions are used for map generation.
Innovation Solution
A system where user devices associated with entities provide radio data to generate and update radio maps, and access to quality information is controlled based on whether the entity's contribution to the map data satisfies specific significance criteria and contribution measures, with quality information being provided or withheld accordingly, and access limited to a threshold number of geographic regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quality information is provided to all users, then users can assess radio map quality and make informed decisions, but bad faith users can obtain accurate positioning data for sabotage or misuse
Solution Approach 1:
The patent implements differential access control where quality information is provided selectively based on user contribution quality. Good faith users who provide accurate radio data receive quality information, while bad faith users do not. This local differentiation of information access resolves the contradiction by allowing reliable users to benefit from quality assessment while preventing misuse by unreliable users.
Solution Approach 2:
The patent introduces an intermediary evaluation mechanism that assesses user contribution quality before granting access to quality information. This intermediary layer acts as a gatekeeper, verifying user reliability through contribution assessment and only allowing authenticated users to access quality information, thereby preventing bad faith users from obtaining sensitive positioning data.
2Object-generated harmful factors
If quality information is withheld from users, then bad faith users cannot misuse the system, but good faith users cannot assess whether additional crowd-sourced information is needed
Solution Approach 1:
The patent applies local quality by providing quality information selectively to users who meet contribution thresholds. Good faith users who actively contribute accurate data receive quality information that enables them to assess coverage gaps and prioritize future data collection efforts, thereby maintaining system productivity while preventing misuse.
Solution Approach 2:
The patent implements a feedback mechanism where quality information is provided to authenticated users to guide their future contributions. Users receive feedback about radio map quality in their area, which motivates them to provide additional crowd-sourced data in regions needing improvement, thus maintaining productivity while controlling access to sensitive information.
3Reliability
If access to quality information is restricted based on contribution criteria, then only reliable users gain access, but the system complexity increases due to contribution evaluation
Solution Approach 1:
The patent manages complexity by establishing clear, quantifiable parameters for contribution evaluation, such as minimum data submission thresholds and accuracy metrics. These parameter-based criteria provide objective, automated evaluation rules that reduce the complexity of assessing user reliability while maintaining high standards for accessing quality information.
Data Source
AI summary
A network device stores a radio map comprising map data configured to enable radio-based positioning within a geographic area. The radio map is associated with a plurality of instances of quality information, with each instance of quality information corresponding to a respective location within the geographic area. The network device receives a quality information request corresponding to a geographic region within the geographic area. The quality information request is associated with an entity. Based on a determination of whether a contribution by the entity to a portion of the map data that corresponds to the geographic region satisfies one or more significance criteria, the network device either provides or withholds quality information corresponding to the geographic region.
