V2X Distribution Module for Seamless Region Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring continuity of Vehicle-to-Everything (V2X) services when vehicles travel across different service regions managed by multiple V2X servers in a multi-server networking architecture.
Innovation Solution
Implementing a cluster-based communication method where vehicles communicate with a distribution module within a cluster, which then routes data to the appropriate regional server, reducing the need for frequent address switching and enhancing service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a multi-V2X server architecture is deployed to cover different service regions, then the service coverage area is expanded, but the frequency of address switching increases and service continuity deteriorates
Solution Approach 1:
The patent divides the V2X server architecture into multiple regional servers (first regional server, second regional server) serving different service regions, allowing the system to scale coverage while managing complexity through structured segmentation. Each regional server handles vehicles in its designated region, enabling expanded coverage without monolithic system complexity.
Solution Approach 2:
The patent introduces a distribution module as an intermediary component that receives data from vehicles and determines which regional server should process the data based on location information. This mediator ensures that vehicles seamlessly switch between regional servers without direct connection complexity, maintaining service continuity across region boundaries.
2Productivity
If vehicles communicate directly with regional servers, then communication efficiency is improved, but the complexity of managing multiple server connections increases
Solution Approach 1:
The distribution module serves as a centralized intermediary that simplifies vehicle-server communication. Instead of vehicles directly managing multiple server connections, they only need to connect to the distribution module, which then routes data to the appropriate regional server based on location information, significantly reducing connection management complexity.
Solution Approach 2:
The distribution module performs multiple functions: receiving data from vehicles, determining service region based on location, selecting the appropriate regional server, and routing data accordingly. This multi-functional design consolidates what would otherwise be multiple separate connection management processes into a single universal component.
3Measurement precision
If the system implements comprehensive location-based routing, then service accuracy is improved, but the processing overhead increases
Solution Approach 1:
The system implements location-based routing by processing location information from vehicles to determine service regions and route data to appropriate servers. The processing overhead is managed by implementing partial action - only processing location information when needed for routing decisions rather than continuously analyzing all possible location parameters, thus achieving sufficient accuracy without excessive processing.
Data Source
AI summary
An internet of vehicles communication method includes receiving reported data of a vehicle, sending the reported data to a first regional server in a first cluster, where the reported data includes information about a first location of the vehicle, receiving information about a second location of the vehicle from the first regional server, where the second location is predicted by the first regional server and is about where the vehicle is to arrive, obtaining an identifier or an address of a second distribution device based on the second location when the second location is outside a service region of the first cluster, and sending the identifier or the address of the second distribution device to the vehicle.
