Satellite Gateway Traffic Balancing via Channel Reassignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunications, especially in satellite systems, the current approach where terminals independently select communication channels based on signal quality can lead to increased backlog and decreased overall throughput due to concurrent reselections, resulting in frustration for users and inefficient resource utilization.
Innovation Solution
A gateway computer system that aggregates inroute channels by symbol rates, determines channel quality and backlog volumes, and transmits instructions to terminals to change channels, thereby balancing traffic load across different symbol rate groups to optimize network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminals independently select channels based on signal quality, then individual terminal performance is optimized, but overall network throughput decreases due to concurrent reselections and increased backlog
Solution Approach 1:
The gateway acts as an intermediary that coordinates channel reselection across all terminals. Instead of terminals making independent decisions, the gateway receives channel quality reports, determines optimal channels centrally, and notifies terminals of the selected channels, preventing concurrent reselection conflicts and optimizing overall network throughput
Solution Approach 2:
The system implements a feedback mechanism where terminals report channel quality metrics to the gateway, which then uses this feedback to make informed channel assignment decisions. The gateway sends notifications back to terminals with optimal channel selections, creating a closed-loop control system that reduces backlog and improves throughput
2Reliability
If terminals frequently reselect channels to maintain optimal signal quality, then individual connection quality is maintained, but network resource utilization becomes inefficient
Solution Approach 1:
The gateway performs preliminary channel quality assessments and predictions before terminals need to reselect. By proactively determining optimal channels based on current network state and traffic patterns, the system prevents unnecessary reselections while maintaining signal quality, thus improving resource utilization
Solution Approach 2:
The system dynamically adjusts channel assignments based on real-time network conditions, terminal traffic patterns, and channel quality metrics. Rather than rigid reselection schedules, the gateway adapts channel allocations dynamically, maintaining signal quality while optimizing resource utilization across the network

AI summary
A system is described that includes a computer programmed: for each of a plurality of terminals, to receive inroute data via one of a plurality of respective inroute channels; using the plurality of respective inroute channels, to determine a first super inroute group (SIG) and a second SIG based on symbol rates of respective inroute channels; to determine a channel quality value of a first inroute channel, of a first terminal, wherein the first inroute channel is one of the plurality of respective inroute channels; to determine a backlog volume of one of the first SIG or the second SIG; and based on determining the channel quality value of the first terminal and the backlog volume of the first or second SIGs, to transmit, to the first terminal, outroute data comprising an instruction to change to a different inroute channel of the first or second SIG.
