DSRC Cellular Integration for Indoor Parking Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking systems face challenges in providing indoor map information and navigation services in areas where GNSS technology is unreliable, such as underground parking garages, especially for vehicles without cellular modems, due to difficulties in positioning and data communication.
Innovation Solution
The integration of dedicated short-range communications (DSRC) with cellular network technologies to enable indoor parking communications, allowing vehicles to receive dynamic parking data through DSRC even without cellular connectivity, using a combination of DSRC and cellular networks for seamless data delivery and integration with online or offline map data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GNSS technology is used for positioning, then outdoor positioning accuracy is improved, but indoor positioning capability deteriorates
Solution Approach 1:
The system segments positioning functionality by deploying separate infrastructure components: GNSS receivers for outdoor positioning and indoor positioning infrastructure (such as Wi-Fi access points, Bluetooth beacons, or other indoor positioning systems) for indoor positioning. This segmentation allows each subsystem to optimize for its specific environment while working together through the server to provide comprehensive positioning coverage.
2Productivity
If cellular network is used for data communication, then data delivery capability is improved, but reliability in areas with limited cellular coverage deteriorates
Solution Approach 1:
The system introduces a server as an intermediary component that receives positioning data from multiple sources (GNSS receivers and indoor positioning infrastructure) and distributes parking facility information to mobile devices. This intermediary architecture enables seamless data delivery by routing information through available communication channels, ensuring reliability even when direct cellular connectivity is limited.
3Adaptability or versatility
If vehicles without cellular modems are supported, then system accessibility is improved, but data communication capability deteriorates
Solution Approach 1:
The system achieves universality by designing the server as a multi-functional platform that can serve both vehicles with cellular modems and those without. The server receives positioning data from various sources and provides parking information through multiple communication channels, enabling vehicles without cellular modems to access parking services through alternative means (such as receiving data via other connected devices or through infrastructure-based communication).
Data Source
AI summary
An apparatus and method for vehicle parking navigation and communication is described. Between a mobile device and a parking server, a first communication link is established. First parking data is received over the first communication link. A parking request including a parking facility identifier is received and a short range communication network is identified, at least in part in response to the parking facility identifier. Between the mobile device and the parking server, a second communication link is established for the short range communication network. Second parking data is received over the second communication link. The first parking data and second parking data may be combined.
