Solution Overview

Problem

Satellite-based communication systems face significant delays due to propagation times, leading to slower initial data transfer rates and user dissatisfaction, especially when multiple data sets need to be transferred, as the round trip and processing delays compound, resulting in frustratingly slow initial speeds and low transfer rates despite high bandwidth connections.

Innovation Solution

The system analyzes data characteristics using deep packet inspection to determine if an accelerated startup is applicable, then sets specific communication parameters such as increased data transmission window sizes and queue service rates for accelerated transfer, followed by adjustments to achieve a predefined transfer rate matching user expectations, thereby counteracting initial delays and maintaining high transfer rates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If standard communication protocols are used for satellite data transfer, then communication reliability is maintained, but initial transfer rate is significantly reduced due to propagation delays

Engineering Contradiction:

Improveinitial transfer rateVSAvoiddelay before data payload transmission

Core Design Contradiction:

SpeedVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-establishing communication connections and exchanging necessary data before the actual data payload transfer. This includes setting up TCP connections, exchanging TCP windows, and preparing communication parameters in advance, so that when data transfer begins, the infrastructure is already in place and ready for immediate high-speed transmission.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces intermediary elements including buffer memory at the satellite terminal, gateway servers that mediate between content sources and terminals, and pre-established connection pools. These intermediaries store data temporarily and manage communication state, allowing the system to overcome propagation delays by decoupling the timing of connection establishment from data payload transmission.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If multiple data sets are transferred sequentially using repeated connection setup, then data transfer completeness is ensured, but overall transfer rate remains low due to compounded delays

Engineering Contradiction:

Improveoverall transfer rateVSAvoidrepeated connection setup time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system merges multiple data transfer operations into a single sustained communication connection. Instead of establishing separate connections for each data set, the patent maintains one persistent TCP connection through which multiple data sets are transferred sequentially without connection teardown and re-establishment, eliminating repeated setup delays.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent ensures continuity of useful action by maintaining persistent communication connections and keeping buffer memory populated with pre-received data. The satellite terminal continuously receives and buffers incoming data streams, ensuring that data transfer operations can proceed without interruption or idle connection setup time between data sets.

Inventive Principle:

Principle #20Continuity of useful action

3Speed

If data is buffered at the satellite terminal, then initial transfer rate is improved, but device complexity increases

Engineering Contradiction:

Improveperceived transfer rateVSAvoidbuffer management complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The buffer management system operates autonomously using self-service mechanisms. The satellite terminal automatically receives data from the gateway, stores it in buffer memory, and serves it to the user device as requested, without requiring complex external coordination. The system self-regulates buffer fill levels and data serving based on incoming data streams and user requests.

Inventive Principle:

Principle #25Self-service

AI summary

Various arrangements for increasing a transfer rate of a data transfer via satellite are presented. A satellite gateway may set an accelerated set of communication parameters that control communication between the satellite gateway and the satellite terminal via the satellite and between the satellite gateway and the content source to an accelerated transfer rate between the content source and the satellite terminal. A first set of data may be transferred from the content source to the satellite terminal using the set of communication parameters. After transferring the first set of data, the satellite gateway may adjust the initial set of communication parameters to an adjusted set of communication parameters. The adjusted transfer rate can be lower than the accelerated transfer rate.
