Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle communication systems fail to dynamically manage communication line allocation and congestion, leading to unclear causes of communication delays and increased processing loads due to frequent retransmissions when congestion occurs.
Innovation Solution
A communication control device and method that detect congestion on communication lines and transmit notifications to applications, allowing them to recognize and respond to congestion by adjusting communication strategies, such as bandwidth limitation and line switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication lines are allocated without dynamic congestion detection, then communication setup is simple, but communication efficiency deteriorates due to frequent retransmissions and unclear delay causes
Solution Approach 1:
The communication control device monitors communication line states and provides feedback notifications to applications when congestion is detected. This feedback mechanism enables applications to adjust their communication behavior based on real-time network conditions, thereby improving communication efficiency by reducing futile retransmissions and clarifying delay causes.
Solution Approach 2:
The system performs preliminary monitoring of communication line states to detect congestion before it severely impacts performance. By detecting congestion early and notifying applications in advance, the system allows applications to preemptively adjust their communication strategies, optimizing resource allocation and reducing the need for repeated retransmissions.
2Reliability
If applications continuously retry communication without congestion awareness, then communication simplicity is maintained, but processing load increases due to futile retries
Solution Approach 1:
The congestion notification system provides applications with real-time feedback about network conditions. When congestion is detected, the communication control device sends notifications to affected applications, enabling them to suspend or adjust communication attempts. This feedback mechanism improves reliability by preventing futile retries while reducing processing load by eliminating unnecessary communication attempts during congested periods.
3Productivity
If communication lines are not dynamically managed, then system complexity is low, but communication resource allocation is suboptimal
Solution Approach 1:
The system dynamically manages communication line allocation based on real-time congestion conditions. The communication control device continuously monitors network states and adjusts resource allocation by notifying applications of congestion events. This dynamic management optimizes communication resource allocation by directing traffic away from congested lines and toward available resources, improving overall system productivity.

AI summary
Disclosed is a technique for controlling communication between a subject device and an external device. The communication is performed via a second network by an application executed by the subject device connected to a first network different from the second network. In the controlling, occurrence of congestion on a communication line used for the communication is detected by monitoring a state of the communication line. Based on the detecting the occurrence of congestion, a notification is transmitted to the application that has used the communication line on which the occurrence of congestion has been detected. The notification indicates congestion on the communication line in use.
