Venue-secured Application for Indoor Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems face challenges in providing reliable location services indoors due to the unreliability of satellite signals, and there is a need to control and restrict access to venue infrastructure information for security and monetization purposes.
Innovation Solution
A venue-secured application is hosted on a mobile station to manage and restrict access to venue infrastructure information, such as digital maps and RF beacon transmitter locations, based on user privilege levels, using techniques like trilateration and heatmap data for location estimation and trajectory calculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite positioning systems are used for navigation, then outdoor navigation services can be provided, but the system becomes unreliable in indoor environments where satellite signals cannot be received
Solution Approach 1:
The patent implements a multi-functional positioning system that can operate in both outdoor and indoor environments. The mobile station is configured to use satellite positioning systems when outdoors and transition to terrestrial wireless access point-based positioning when indoors, creating a universal navigation solution that adapts to different environmental contexts without requiring separate systems.
Solution Approach 2:
The system dynamically switches between different positioning methods based on the detected environment. The mobile station continuously monitors signal availability and automatically transitions between satellite-based and terrestrial-based positioning techniques, ensuring reliable navigation services regardless of whether the user is indoors or outdoors.
2Ease of operation
If venue infrastructure information is provided to all mobile stations, then comprehensive navigation services are available, but security and monetization policies cannot be enforced
Solution Approach 1:
The patent implements differential information distribution where different mobile stations receive different subsets of venue infrastructure information based on their privilege levels. High-privilege users receive complete venue maps and access point locations, while standard users receive only the information necessary for basic navigation, enforcing security and monetization policies through localized information quality.
Solution Approach 2:
The venue infrastructure information is segmented into multiple levels of detail and selectively distributed to mobile stations based on user privilege levels. The system divides comprehensive venue data into hierarchical layers, providing only the appropriate segment to each user type, thereby maintaining security controls while enabling navigation services for all users.
