Vehicle Message Filtering by Validity Time and Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-infrastructure and vehicle-to-vehicle communication technologies experience delays and inefficiencies due to excessive information interaction, leading to overhead and reduced communication efficiency.
Innovation Solution
An electronic apparatus for vehicles and road side units that utilize processing circuitry to determine and include effective time and range in messages, allowing vehicles to selectively forward messages based on these parameters, thereby optimizing information interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicles broadcast and forward all received messages to ensure information completeness, then information coverage is improved, but communication overhead and time delay increase
Solution Approach 1:
The patent applies local quality by making each vehicle's message forwarding behavior context-dependent rather than uniform. Vehicles evaluate local conditions (effective time, effective range, destination matching) to determine whether to forward a message, allowing the system to maintain information coverage where needed while avoiding unnecessary forwarding that would increase delay. This selective forwarding based on local relevance resolves the contradiction between complete information dissemination and timely delivery.
2Loss of information
If vehicles forward all received messages to maintain information completeness, then information coverage is improved, but communication overhead increases
Solution Approach 1:
The patent extracts only the relevant portions of message forwarding based on predefined criteria (effective time, effective range, destination). Instead of forwarding entire message sets uniformly, the system extracts and forwards only those messages that meet the relevance conditions, thereby reducing communication overhead while maintaining necessary information coverage. This selective extraction resolves the contradiction between complete information propagation and overhead reduction.
3Measurement precision
If messages include detailed effective time and range parameters, then message relevance accuracy is improved, but message size and processing complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-defining the structure and parameters of messages (effective time, effective range, destination) before transmission. This allows receiving vehicles to quickly evaluate message relevance using predetermined criteria without complex real-time analysis, thereby maintaining high message relevance accuracy while minimizing processing complexity. The pre-structured message format enables efficient filtering and forwarding decisions.

AI summary
The present disclosure relates to an electronic device, a radio communication method, and a computer-readable storage medium. The electronic device of the present disclosure for use in a vehicle is configured to: receive a message, the message comprising a validity time of the message and a validity range of the message; and determine, on the basis of the validity time of the message and of the validity range of the message, whether to forward the message. The use of the electronic device, the radio communication method, and the computer-readable storage medium of the present disclosure optimizes an exchange process for vehicle-related information, thus reducing overhead and delays to the greatest extent, and thereby increasing communication efficiency.
