Vehicle Information Distribution via Forwarding Area Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing V2X communication systems, vehicles within different service areas cannot receive V2X messages from each other, even when they are close, leading to potential safety issues due to limited communication range between base stations.
Innovation Solution
A method and system that calculate a forwarding area based on the distance or intersection between service areas, allowing vehicle information to be transferred and broadcast across base stations, enabling vehicles in different service areas to share safety messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2X messages are broadcast only within the service area of the same base station, then the system maintains simple base station operation and limited broadcast scope, but vehicles in different service areas cannot receive safety messages from neighboring areas, reducing road safety
Solution Approach 1:
The application server acts as an intermediary between base stations, receiving vehicle information from one base station and forwarding it to neighboring base stations. This mediator approach enables cross-service-area message distribution without requiring direct complex inter-base-station communication protocols, thus improving road safety while keeping base station operations relatively simple
Solution Approach 2:
The system divides the vehicle information distribution task into segments: each base station collects information from its own service area, the application server consolidates and routes information between base stations, and each base station broadcasts received information. This segmentation allows complex multi-area coordination to be broken down into simpler, manageable steps for each component
2Reliability
If the broadcast range is extended to cover multiple service areas, then vehicles can receive safety messages from neighboring areas, but the energy consumption and communication load of the system increase
Solution Approach 1:
The system implements partial action by having base stations forward vehicle information only to neighboring base stations with overlapping or adjacent service areas, rather than broadcasting to all base stations in the network. The application server calculates forwarding areas based on service area intersections, ensuring messages are propagated only as far as necessary to cover vehicles in neighboring areas, thus extending safety coverage while limiting energy consumption
3Loss of information
If all base stations broadcast all received vehicle information to all service areas, then complete information coverage is achieved, but the network traffic and processing load increase significantly
Solution Approach 1:
The system applies local quality by having each base station broadcast vehicle information only within its own service area and to neighboring base stations, rather than distributing information network-wide. The application server determines forwarding areas based on service area intersections, ensuring that information is propagated locally to where it is needed (neighboring service areas) without creating unnecessary network-wide traffic, thus maintaining information coverage while reducing overall network traffic volume

AI summary
A vehicle information distributing method is provided, including: receiving a plurality of first vehicle information from a first base station to determine a first service area; receiving a plurality of second vehicle information from a second base station to determine a second service area; calculating a forwarding area based on a distance or an intersection between the first service area and the second service area; transferring the first vehicle information within the forwarding area to the second base station, and transferring the second vehicle information within the forwarding area to the first base station; and broadcasting, by the first base station, the second vehicle information from the forwarding area, and broadcasting, by the second base station, the first vehicle information from the forwarding area.
