V2X Middleware Layer for Message Distribution Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a link layer mechanism for unicast communications over PC5 in V2X communication, leading to challenges in controlling V2X message distribution effectively among a group of V2X UEs, particularly in dense scenarios where message broadcast flooding can occur and ensuring reliable reception of safety/efficiency messages.
Innovation Solution
Implementing a V2X middleware layer that configures and manages V2X message transmission/reception based on application requirements, service coverage, and traffic conditions, using techniques such as UE-to-UE virtual user graphs and message bundling to prevent flooding and ensure message reachability.

Engineering Contradiction Analysis
1Reliability
If V2X messages are broadcast to all UEs in dense scenarios, then message reachability is improved, but broadcast flooding occurs causing network overload
Solution Approach 1:
The patent segments the broadcast domain by introducing a configuration policy that divides UEs into different groups based on service coverage areas. Instead of broadcasting to all UEs uniformly, messages are targeted to specific UE groups, preventing broadcast flooding while ensuring reachability to the intended recipients.
Solution Approach 2:
The patent introduces a configuration policy as an intermediary mechanism that mediates between the message source and target UEs. This policy acts as a filter that determines which UEs should receive which messages based on their service coverage areas, preventing unnecessary message propagation and flooding.
2Object-generated harmful factors
If configuration policy is distributed to control V2X message distribution, then broadcast flooding is prevented, but device complexity increases
Solution Approach 1:
The configuration policy serves multiple functions simultaneously: it defines service coverage areas, identifies target UEs for message distribution, and controls message routing. This multi-functionality reduces the need for separate mechanisms and minimizes overall system complexity despite the policy's comprehensive role.
