Vehicle Relay Server Port Separation for Proxy Traffic Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems face challenges in managing data traffic accurately when proxy communication is introduced, as the traffic of individual vehicles becomes unclear due to data being taken over by another vehicle, leading to unclear traffic distribution.
Innovation Solution
A vehicle communication system with a relay server that manages data traffic by using distinct ports for normal and proxy communications, allowing the relay server to differentiate between the two types of traffic based on port numbers, and includes communication devices capable of cellular, vehicle-to-vehicle, and Wi-Fi communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proxy communication is introduced to enable one vehicle to take over data communication for another vehicle, then communication reliability is improved, but traffic management precision deteriorates because the relay server cannot distinguish between normal and proxy communication traffic
Solution Approach 1:
The patent applies the principle of using distinct port numbers as identifiers to differentiate between normal communication and proxy communication. The communication device uses a first port for normal communication and a second port for proxy communication, allowing the relay server to distinguish traffic types based on port numbers, thereby maintaining both communication reliability and traffic management precision
2Device complexity
If a single port is used for both normal and proxy communication, then device complexity is reduced, but the ability to manage and differentiate traffic types deteriorates
Solution Approach 1:
The patent segments the communication channels by assigning different port numbers to different communication types. The communication device is configured to use a first port for normal communication and a second port for proxy communication, enabling the relay server to separately manage and differentiate traffic without increasing overall system complexity
Data Source
AI summary
Each of a first communication device and a second communication device is capable of performing vehicle-to-vehicle communication and cellular communication. The first communication device issues a proxy request to the second communication device for communication with an application server. When the second communication device receives proxy communication, the second communication device acquires an unused port number from the first communication device, notifies a relay server of the port number as the number of the port for proxy communication, and then performs the proxy communication.
