V2X Vehicle Location Tracking Beyond Cellular Granularity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular-based vehicle tracking provides limited location granularity, and there is a need for more precise tracking of vehicles in situations like vehicle theft or incidents involving law enforcement, where the location of the vehicle is of primary interest.
Innovation Solution
Utilizing Vehicle to Everything (V2X) communication to enhance vehicle tracking by receiving a tracking request, creating a target vehicle list, distributing it to V2X endpoints, and forwarding sighting reports to a network element for lawful interception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cellular-based tracking is used, then the tracking system is simple to implement, but the location granularity is limited
Solution Approach 1:
The patent introduces V2X communication as an intermediary layer between the vehicle and the tracking system. Instead of directly using cellular networks for precise location tracking, the system uses V2X endpoints (vehicles, road-side units) as intermediaries to detect and report target vehicle locations through V2X messages, thereby achieving high-resolution tracking without direct cellular intervention at the vehicle level
Solution Approach 2:
The tracking system leverages the existing V2X communication infrastructure where vehicles and road-side units already broadcast their location information for cooperative driving purposes. The system repurposes these self-service V2X messages for tracking without requiring additional dedicated tracking hardware or infrastructure in vehicles
2Measurement precision
If V2X communication is used for tracking, then the location tracking precision is improved, but the system complexity increases
Solution Approach 1:
The system uses V2X communication infrastructure that serves multiple purposes: both cooperative driving (safety messages) and law enforcement tracking. The same V2X endpoints, messages, and network elements used for vehicle-to-vehicle safety communication are also utilized for tracking, eliminating the need for separate dedicated tracking infrastructure
Solution Approach 2:
The patent introduces V2X communication as an intermediary layer between the vehicle and the tracking system. Instead of directly using cellular networks for precise location tracking, the system uses V2X endpoints (vehicles, road-side units) as intermediaries to detect and report target vehicle locations through V2X messages, thereby achieving high-resolution tracking without direct cellular intervention at the vehicle level
3Measurement precision
If cellular communication is used for lawful interception, then the implementation is straightforward, but the tracking capability is limited to cell-level granularity
Solution Approach 1:
The patent introduces V2X communication as an intermediary layer between the vehicle and the tracking system. Instead of directly using cellular networks for precise location tracking, the system uses V2X endpoints (vehicles, road-side units) as intermediaries to detect and report target vehicle locations through V2X messages, thereby achieving high-resolution tracking without direct cellular intervention at the vehicle level
Solution Approach 2:
The system pre-distributes target vehicle lists to V2X endpoints before the actual tracking is needed. Law enforcement can request tracking of a vehicle, and the system proactively pushes the target vehicle list to relevant V2X endpoints in advance, so that when the target vehicle enters the monitoring area, immediate detection can occur without delay
