V2X Server and RSU Relay Using Virtual Subscription Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X technologies primarily focus on vehicle safety through direct vehicle-to-vehicle communication, and there is a need to extend these services to include pedestrians and other electronic devices, as well as improve communication efficiency and coverage for diverse users and devices.
Innovation Solution
A server and road side unit (RSU) device for vehicle-to-everything (V2X) services that configure virtual subscription areas, receive and transmit V2X messages, and manage legacy devices by setting virtual subscription and publishing areas to enhance communication coverage and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If direct vehicle-to-vehicle communication is used for V2X services, then vehicle safety is improved, but the system cannot provide services to pedestrians and other electronic devices
Solution Approach 1:
The patent introduces RSU (Road Side Unit) and server as intermediary components in the V2X communication system. The RSU acts as a mediator between vehicles and the server, enabling legacy V2X devices to communicate through infrastructure rather than direct peer-to-peer links. This allows pedestrians and electronic devices to be included in V2X services while maintaining communication reliability through the structured intermediary architecture.
2Area of stationary object
If virtual subscription areas are configured for legacy V2X devices, then communication coverage is improved, but system complexity increases
Solution Approach 1:
The patent segments the service area into virtual subscription areas that can be independently configured and managed. Each legacy V2X device is assigned a specific virtual subscription area, allowing the system to extend coverage to diverse users and devices without requiring a complete system redesign. This segmentation approach manages complexity by creating modular, manageable units within the overall communication framework.
Data Source
AI summary
A vehicle-to-everything (V2X) server for providing a V2X service can include a processor; and a memory operatively coupled with the processor and configured to store instructions that, when executed by the processor, cause the V2X server to perform functions comprising configuring a virtual subscription area for a legacy V2X device; receiving a V2X message from a V2X device associated with the virtual subscription area; and transmitting the V2X message to a road side unit (RSU) device managing the legacy V2X device for relaying the V2X message to the legacy V2X device.
