Network-Controlled Vehicle Sensor Sharing for Targeted V2X Queries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-vehicle communication systems face challenges in efficiently sharing sensor information due to limitations in identifying and connecting with vehicles not actively connected to the V2X application server, leading to potential sensor data overload and inability to meet latency and reliability requirements.
Innovation Solution
A network-controlled on-demand query mechanism that targets a specific geographical area to identify and trigger vehicles to share sensor information, enabling direct communication between vehicles without relying on continuous server aggregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If continuous server aggregation is used to collect sensor data from all vehicles, then comprehensive sensor information coverage is improved, but network burden and data overload increase
Solution Approach 1:
The patent extracts only the necessary sensor information from vehicles based on specific query criteria rather than aggregating all sensor data continuously. The network entity sends targeted queries requesting only relevant sensor data from vehicles in the geographical area, thereby reducing network burden while maintaining information coverage.
Solution Approach 2:
Instead of continuously collecting data from all vehicles (excessive action), the system performs partial data collection only when queried and only from vehicles that can provide relevant information. This on-demand approach reduces overall network traffic while ensuring necessary information is obtained.
2Ease of operation
If request-response mechanism is used for sensor sharing, then direct vehicle-to-vehicle communication is enabled, but vehicles in idle mode cannot be identified and connected
Solution Approach 1:
The patent introduces a network entity as an intermediary between vehicles. This network entity maintains awareness of vehicles in idle mode and their sensor capabilities, enabling the system to identify and query idle vehicles for sensor information without requiring them to be actively connected to the V2X application server.
Solution Approach 2:
The network entity performs preliminary identification and tracking of vehicles in idle mode, maintaining information about their sensor capabilities and geographical locations. This preliminary action enables reliable connection and querying of idle vehicles when sensor information is needed, without requiring continuous active connection.
3Quantity of substance
If on-demand querying is implemented for specific geographical areas, then network burden is reduced, but identification and triggering of target vehicles becomes more complex
Solution Approach 1:
The patent segments the querying process into distinct functional components: geographical area specification, vehicle identification based on location, query formulation and transmission, and response handling. This segmentation manages complexity by breaking down the on-demand querying mechanism into manageable, modular steps that can be independently implemented and maintained.

AI summary
Certain aspects of the present disclosure provide techniques relating to network controlled sensor information sharing between vehicles. In one embodiment, a method of wireless communications by a network entity comprises receiving a request, from a first user equipment (UE), for sharing of sensor information by at least a second UE based on a target region indicated by the request and taking one or more actions, in response to the request, to trigger the sharing of sensor information by the second UE.
