Communication Node Channel Switching for Interruption Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems are not reliable in quickly detecting and mitigating interruptions in communication channels, leading to prolonged unconnected times when a channel is disrupted.
Innovation Solution
Each communication node tracks successful data signal receptions and initiates a switch to an alternative channel if no reception is made within a given time interval, using stored usability information to determine a channel sequence for switching, allowing the system to be self-organized without a central node and continue communication even if nodes fail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication nodes wait for confirmation of successful reception before switching channels, then false channel switching is reduced, but channel interruption detection time increases
Solution Approach 1:
The system performs preliminary actions by sending broadcast signals and tracking reception status proactively. Nodes continuously monitor whether data signals are successfully received within expected time intervals, and initiate channel switching requests before complete communication failure occurs. This preliminary detection mechanism reduces the time nodes remain unconnected while maintaining reliable switching decisions.
Solution Approach 2:
The system implements feedback mechanisms where communication nodes track successful reception of data signals and provide feedback about channel status. When nodes detect that no successful receptions have occurred within a given maximum time interval, they send broadcast signals to request channel switches. This feedback loop enables timely detection of channel interruptions while ensuring switching decisions are based on actual reception status.
2Device complexity
If a central station manages communication channels, then channel coordination is simplified, but system reliability decreases due to single point of failure
Solution Approach 1:
The system segments the centralized channel management function and distributes it to individual communication nodes. Each node independently tracks reception status and can autonomously request channel switches by sending broadcast signals. This segmentation eliminates the single point of failure associated with centralized management while maintaining coordinated channel switching through distributed decision-making among nodes.
Solution Approach 2:
Communication nodes perform self-service by autonomously monitoring their own reception status and initiating channel switching requests when necessary. Each node tracks successful data signal receptions independently and can request channel switches without requiring a central coordinating station. This self-service capability enhances system reliability by removing the central point of failure while maintaining organized channel management through distributed node actions.

AI summary
The invention relates inter alia to a method of operating a communication system (10). Each communication node (11, 12, 13, 14) of the communication system (10) preferably tracks a successful reception of data signals (D) and requests a switch and/or switches from a currently used communication channel (C1) to another communication channel (C2-C6) in case that no successful receptions were made within a given maximum time interval.
