Adaptive ModCod Selection for Satellite Service Plans
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internet satellite service plans based on traffic priority and raw data usage fail to account for bandwidth efficiency losses during signal degradation, penalizing higher rate plan subscribers and inefficiently utilizing network resources.
Innovation Solution
Implementing tiered service plans that limit lower-cost subscribers to higher capacity, less robust ModCods during signal degradation, while allowing higher-cost subscribers to use a wider range of ModCods, thereby optimizing bandwidth usage and service availability based on signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all users are allowed to operate on the entire set of operational ModCods regardless of service plan, then service availability is maintained for all users, but bandwidth efficiency is lost when lower revenue users force the system to use higher availability coding rates during signal degradation
Solution Approach 1:
The patent applies local quality by assigning different ModCod operating characteristics to different service plans. Premium service plans are permitted to use higher order ModCods (e.g., 8PSK, 16APSK) that offer higher throughput but lower availability, while standard service plans are restricted to lower order ModCods (e.g., QPSK, 8QAM) that provide better availability but lower throughput. This differentiation allows the system to optimize bandwidth efficiency during signal degradation by preventing standard users from forcing premium bandwidth resources to be used at reduced efficiency.
Solution Approach 2:
The patent segments the ModCod operating space into different service plan categories. The ModCod set is divided into premium-tier ModCods and standard-tier ModCods, with each service plan having authorized access to specific segments. This segmentation enables the system to manage bandwidth resources efficiently by ensuring that users pay for and receive service levels相匹配 to their subscription, while maintaining service availability for all users within their authorized parameters.
2Reliability
If lower order ModCods are used to ensure robustness during signal degradation, then service availability is improved, but bandwidth consumption increases
Solution Approach 1:
The patent utilizes parameter changes by allowing the ModCod order and type to vary dynamically based on both signal conditions and service plan authorization. During signal degradation, the system adapts by selecting appropriate ModCods from each user's authorized set. Premium users can transition to more efficient ModCods that maintain higher throughput even in degraded conditions, while standard users transition to more robust ModCods within their authorized set. This parameter adaptation resolves the contradiction by matching ModCod selection to both channel conditions and service level agreements.
3Quantity of substance
If higher order ModCods are used to reduce bandwidth consumption, then bandwidth efficiency is improved, but service availability decreases due to reduced robustness to signal degradation
Solution Approach 1:
The patent implements dynamics by enabling continuous adaptation of ModCod selection based on real-time signal quality measurements and service plan parameters. The system dynamically transitions between different ModCods as signal conditions change, with each service plan having a defined range of authorized ModCods. Premium service plans authorize access to higher order ModCods (16APSK, 8PSK) that provide better bandwidth efficiency, while standard plans authorize lower order ModCods (QPSK, 8QAM) that provide better availability. This dynamic adaptation resolves the contradiction by allowing each user class to operate optimally within their authorized parameters.

AI summary
A method for providing service levels in a Radio Frequency (RF) network is disclosed. The method including: associating one or more service levels with each supported symbol rate, modulation and error correction encoded scheme (ModCod); assigning a subscriber service level for a RF transmitter; receiving a signal quality of a transmission by the RF transmitter; selecting a transmit ModCod from the supported ModCods, wherein the signal quality exceeds a threshold signal quality for the transmit ModCod; and authorizing the RF transmitter to transmit to the receiver when the subscriber service level is included in the one or more service levels associated with the transmit ModCod, wherein signal quality adapts to a signal fade.
