Vehicle Information Provision via Multi-Slice Network Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic systems face challenges in providing information to target vehicles in a flexible manner due to data volume, communication delay, and processing delay, requiring a more efficient method to offer suitable information to vehicles.
Innovation Solution
A wireless communication system with an information providing terminal, base station, server, and information acquiring terminal, where a determination unit decides on the adoption of provision information based on the vehicle's position and associated source data, allowing for flexible and timely information provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized processing is used to provide information to target vehicles, then information provision reliability is improved, but system complexity and construction costs increase
Solution Approach 1:
The system segments information provision into multiple network slices (first slice for direct terminal-to-terminal communication, second slice for base station-mediated communication, third slice for server-mediated communication). Each slice handles different types of information provision tasks, dividing the centralized processing function into distributed components that can operate independently, thus reducing overall system complexity while maintaining reliability through multi-path information delivery.
2Loss of information
If more provision information is transmitted to target vehicles, then information completeness is improved, but data volume and processing delay increase
Solution Approach 1:
The system applies local quality by determining whether to adopt provision information based on the specific position of the target vehicle and the position associated with the source data. The determination unit selectively processes and transmits only the relevant information subsets that match the vehicle's current context, rather than transmitting all available information. This ensures information completeness for the specific local situation while reducing overall data volume and processing delay.
3Productivity
If direct terminal-to-terminal communication is used, then communication efficiency is improved, but information provision flexibility deteriorates
Solution Approach 1:
The system implements dynamics by allowing the information provision path to dynamically switch between different network slices based on the determination result. When direct terminal-to-terminal communication in the first slice is sufficient, it provides high efficiency. When more flexibility is needed, the system can dynamically transition to base station-mediated (second slice) or server-mediated (third slice) communication. This dynamic adaptability resolves the contradiction by allowing the system to optimize for efficiency or flexibility depending on the specific situation.
