Satellite Inroute Quarantine for Burst Error Rate Shedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional error correction and mitigation techniques in satellite communication systems become inefficient when high burst error rates are limited to specific inroutes, leading to data loss, reduced throughput, and increased latency.
Innovation Solution
Intelligent inroute shedding is implemented by monitoring burst error rates, quarantining bad inroutes, redistributing terminals, and periodically re-checking their status to determine whether they should be returned to service or permanently quarantined.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional error correction and mitigation techniques are employed to detect and correct errors, then reliability is improved, but device complexity and inefficiency increase when high burst error rates are limited to particular inroutes
Solution Approach 1:
The patent segments the communication system into individual inroutes (communication paths) and monitors them separately. When a specific inroute exhibits high burst error rates, it is identified and isolated from the rest of the system, allowing error correction resources to be focused only where needed rather than applying complex correction across all routes uniformly.
Solution Approach 2:
The patent applies local quality by treating different inroutes differently based on their error characteristics. Instead of applying uniform error correction to all inroutes, the system identifies specific inroutes with high error rates and applies enhanced correction only to those local areas, optimizing the balance between reliability and complexity.
2Reliability
If error correction techniques are applied to improve reliability, then data integrity is improved, but productivity is reduced due to substantial inefficiencies in handling localized high burst error rates
Solution Approach 1:
The patent extracts problematic inroutes with high burst error rates from the active communication system and places them in a quarantine state. This removes the inefficiency from the overall system operation, allowing other inroutes to maintain full productivity while the quarantined inroutes are addressed separately through targeted error correction or permanent isolation.
Solution Approach 2:
The system performs preliminary monitoring and identification of inroutes with high burst error rates before they significantly impact overall system productivity. By detecting and quarantining problematic inroutes early, the system prevents widespread inefficiency and maintains higher overall throughput.
3Reliability
If all inroutes are continuously monitored and managed, then reliability is improved, but loss of time increases due to the overhead of monitoring and re-checking inroutes
Solution Approach 1:
The patent implements dynamic monitoring where the system adapts its monitoring intensity based on inroute conditions. Inroutes that are functioning normally are monitored at lower intensity, while only inroutes that exhibit high burst error rates receive intensive monitoring and quarantine actions. This dynamic approach maintains reliability without the full overhead of continuous intensive monitoring of all routes.

AI summary
Techniques are described herein for intelligent shedding of inroutes determined to have high burst error rates. Embodiments operate in context of a multi-spot beam satellite communication system that uses time-division multiple access (TDMA) communication protocols and inroute groups. Burst error rates of inroutes can be monitored over time to identify bad inroutes. Each bad inroute can be shut down and quarantined. After a predetermined amount of time, one or more selected terminals can be redistributed to the bad inroutes, and the burst error rates of those inroutes can be monitored again to determine whether those inroutes should remain quarantined. If an inroute is no longer bad, it can be removed from quarantine and returned to an inroute group list. If the inroute is still bad, it can be periodically re-checked until it ultimately improves, is permanently quarantined, etc.
