Vehicle Network Traffic Management via Application Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle information utilization networks experience increased communication traffic due to unnecessary data transmission, leading to inefficiencies and a need to grasp the communication status on the network to reduce this traffic.
Innovation Solution
A vehicle network system with a management server and in-vehicle devices that measure and aggregate communication traffic for each application program, allowing the management server to identify and manage communication traffic, and implement restrictions when necessary to control excessive usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all in-vehicle data is transmitted to the server device, then complete data collection is achieved, but communication traffic increases due to unnecessary data transmission
Solution Approach 1:
The patent segments communication traffic into different application programs and identifies them using application identification data. This allows the system to analyze and manage traffic from each application separately, enabling selective transmission of necessary data while filtering out unnecessary traffic, thus reducing overall communication load while maintaining data collection completeness.
Solution Approach 2:
The patent changes the parameter of traffic analysis by introducing application identification data as a new dimension for categorizing and managing communication traffic. This parameter change enables the system to distinguish between necessary and unnecessary data transmissions based on application type, allowing for optimized data selection and reduced communication traffic.
2Adaptability or versatility
If multiple application programs are executed on in-vehicle devices, then functional versatility is improved, but communication traffic management complexity increases
Solution Approach 1:
The patent segments communication traffic by application program, using application identification data to categorize traffic from each application separately. This segmentation simplifies the management of multiple applications by providing a structured approach to analyze and control traffic from each application independently, reducing the overall complexity of managing diverse application traffic.
3Productivity
If communication traffic is monitored and restricted for excessive service providers, then network efficiency is improved, but system control complexity increases
Solution Approach 1:
The patent introduces application identification data as a new parameter for monitoring and controlling communication traffic. This parameter change enables the system to automatically identify, analyze, and restrict traffic from specific applications or service providers that exceed acceptable thresholds, improving network efficiency through automated parameter-based control rather than manual management.
