Global Bandwidth Management for Satellite Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite network bandwidth is inefficiently used due to constant demand fluctuations, as unused capacity is not reallocated to parties requiring bandwidth, leading to inefficiencies in resource utilization.
Innovation Solution
A global bandwidth management system that allocates bandwidth from a shared pool across multiple satellites and beams based on a group service plan with predetermined geographic scope, dynamically adjusting Quality of Service (QoS) parameters like CIR, MIR, and cost to ensure efficient resource distribution and reallocation.

Engineering Contradiction Analysis
1Productivity
If bandwidth is allocated to a group of terminals within a satellite network, then service capacity is provided to the organization, but network resources are inefficiently used when bandwidth demands are low due to unused capacity not being reallocated
Solution Approach 1:
The patent implements dynamic bandwidth management by creating a global bandwidth pool that can be dynamically allocated and reallocated across multiple satellites and beams. The system continuously monitors bandwidth demand and dynamically adjusts allocations based on real-time requirements, transitioning from static to dynamic resource distribution. This enables efficient utilization of network resources by reallocating unused capacity to other terminals or services that need it.
Solution Approach 2:
The patent merges the bandwidth resources from multiple satellites and beams into a single global bandwidth pool. This consolidation allows the system to view and manage all available capacity as one unified resource, enabling cross-satellite and cross-beam reallocation of unused bandwidth. The merging of resources facilitates more flexible and efficient allocation decisions that consider the entire network rather than isolated components.
2Productivity
If static channel configurations are used in satellite networks, then system simplicity is maintained, but resource distribution efficiency deteriorates due to inability to adapt to demand fluctuations
Solution Approach 1:
The patent segments the global bandwidth into manageable portions associated with different satellites, beams, and service types while maintaining a unified pooling mechanism. This segmentation allows complex reallocation decisions to be broken down into smaller, more manageable units that can be independently allocated and reallocated. The segmentation principle enables efficient resource distribution by creating flexible allocation granules that can adapt to varying demands without requiring complete system redesign.
Solution Approach 2:
The system incorporates feedback mechanisms that continuously monitor bandwidth usage patterns, demand fluctuations, and network conditions. This feedback information is used to automatically adjust bandwidth allocations in real-time, enabling the system to adapt to changing requirements without manual intervention. The feedback loop closes by measuring the impact of allocation changes and using this information to optimize future decisions, thereby improving resource distribution efficiency through data-driven control.
