Multilink Aircraft Communication Controller Link Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft communication systems face challenges in efficiently selecting the best communication link for message delivery due to varying constraints such as cost, bandwidth, and ionospheric interference, especially in high-density airspace, leading to delayed message delivery and reduced communication efficiency.
Innovation Solution
A multilink communication controller with a link selection table and selector that determines the best communication link based on message priority, link quality, and cost information, using real-time measurements and dynamic performance metrics to optimize link selection and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual or predetermined link selection is used, then communication links are available for message delivery, but message delivery is delayed due to serial link selection process
Solution Approach 1:
The system dynamically selects communication links based on real-time message priority and link quality conditions, rather than using static manual or predetermined selection. The link selector continuously evaluates multiple communication links and adapts the selection to current operational needs, enabling faster message delivery while optimizing communication efficiency
Solution Approach 2:
The system changes the selection parameter from manual/predetermined fixed choices to dynamic priority-based selection. By incorporating message priority levels and real-time link quality metrics, the system transforms the link selection process into a parameter-driven automated decision-making process that reduces delivery time and improves overall communication productivity
2Productivity
If multiple communication links are monitored and evaluated in real-time, then message delivery efficiency is improved, but system complexity increases
Solution Approach 1:
The system segments the link selection process into distinct functional components: a link monitor that evaluates communication link conditions, a message priority determiner that assigns priority levels, and a link selector that makes selection decisions. This segmentation allows each component to perform its specific function independently, improving communication efficiency while managing system complexity through modular design
Solution Approach 2:
The link selector acts as an intermediary component that receives inputs from multiple sources (link quality data, message priority information) and produces the final link selection output. This intermediary structure simplifies the overall system architecture by centralizing the decision-making logic and providing a clear interface between monitoring functions and communication transmission, thereby improving efficiency without proportionally increasing complexity

AI summary
An aircraft communication system includes, and a method of aircraft communication uses, communication radios and a multilink communication controller. The multilink communication controller includes a link selection table and a link selector. The link selector is in communication with the link selection table. The link selector is configured to receive a message from a system of the aircraft and select a communication link among a number of communication links for the message using a priority of the message and priority information from the link selection table.
