Peer-to-Peer Location Exchange for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current location-based services rely on centralized systems, which lead to performance issues, high infrastructure costs, and privacy concerns due to the need for a middleman service for location-dependent features and functionality, and existing methods for automatically locating mobile devices are costly and time-consuming.
Innovation Solution
The introduction of Location Based eXchanges (LBX) enables peer-to-peer interactions among mobile data processing systems to provide location-based features and functionality without a centralized service, using indirect location methods such as triangulation and Assisted Direct Location Technology to automatically detect and share locations among devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized service systems are used for location-based services, then location-dependent features and functionality can be provided, but infrastructure costs increase and performance bottlenecks occur
Solution Approach 1:
The patent extracts the location determination functionality from centralized service systems and implements it directly in mobile devices through peer-to-peer location exchanges. This eliminates the need for costly centralized infrastructure while maintaining location-based service functionality, directly resolving the contradiction between service reliability and infrastructure complexity
Solution Approach 2:
Mobile devices perform location determination independently through peer-to-peer interactions with other devices, rather than relying on centralized service providers. This self-service approach eliminates infrastructure costs while preserving location-based functionality, resolving the technical contradiction
2Reliability
If centralized service systems are used for location-based services, then location features can be provided, but response time performance deteriorates
Solution Approach 1:
The patent removes the intermediate centralized service layer and enables direct peer-to-peer location exchanges between mobile devices. This extraction eliminates the performance bottleneck of centralized processing while maintaining location-based service functionality, resolving the contradiction between reliability and response speed
Solution Approach 2:
The patent eliminates the centralized service intermediary that causes response time delays. By enabling direct device-to-device location exchanges, the system removes the mediating layer that creates performance bottlenecks, thereby improving response time while preserving functionality
3Reliability
If centralized service systems are used for location-based services, then location features can be provided, but user privacy is compromised
Solution Approach 1:
The patent extracts location data processing from centralized service systems and keeps it distributed across individual devices through peer-to-peer exchanges. This extraction prevents centralized collection of user location information, thereby protecting privacy while maintaining location-based service functionality
Solution Approach 2:
Devices independently determine their own locations through peer-to-peer interactions without submitting location data to centralized services. This self-service approach maintains location functionality while preventing privacy-compromising centralized data collection
4Measurement precision
If traditional direct location methods are used for mobile devices, then location accuracy can be achieved, but deployment costs and time increase
Solution Approach 1:
The patent enables mobile devices to determine their locations autonomously through peer-to-peer location exchanges with other devices. This self-service approach provides accurate location measurement without requiring costly centralized infrastructure deployment, resolving the contradiction between measurement precision and deployment complexity
Solution Approach 2:
The patent creates a universal location determination system where any mobile device can serve as a location reference for other devices. This multi-functional approach eliminates the need for specialized expensive infrastructure while maintaining location accuracy through distributed peer-to-peer measurements
Data Source
AI summary
Provided is a distributed system and method for enabling new and useful location dependent features and functionality to mobile data processing systems. Mobile data processing systems interact with each other as peers in communications and interoperability. A mobile data processing system may dynamically take on roles, depending on the environment and capabilities available at a particular time. Reference whereabouts data is appropriately shared between mobile data processing systems to carry out automatic location techniques ensuring mobile data processing systems are kept up to date with their own whereabouts and whereabouts of others, regardless of the freely moving travels of any of the mobile data processing systems involved, and the location technologies that may or may not be available when needed. A confidence is associated to whereabouts data shared for facilitating selection of the best candidate data used in determining new whereabouts information.
