Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing satellite communication systems face challenges in providing consistent and high-quality network access to mobile users due to varying demand patterns, leading to underutilization or congestion, and inefficient resource allocation among fixed and mobile terminals.
Innovation Solution
A satellite communication system that dynamically allocates resources based on user-specific traffic policies, combining per-user QoS control with dynamic multiplexing of traffic from fixed and mobile users on the same satellite beams, using forward and return link traffic shaping to optimize bandwidth allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite systems allocate fixed resources to mobile users, then service consistency is improved, but resource utilization efficiency deteriorates due to varying demand patterns
Solution Approach 1:
The patent implements dynamic resource allocation where the satellite system continuously adjusts resource distribution based on real-time demand patterns. Mobile users are allocated resources dynamically rather than fixed assignments, allowing the system to adapt to varying traffic conditions and maintain service consistency while optimizing resource utilization efficiency.
Solution Approach 2:
The system changes allocation parameters based on demand fluctuations. By monitoring traffic patterns and adjusting resource allocation parameters in real-time, the system maintains consistent service quality while preventing resource waste during low-demand periods and ensuring adequate capacity during high-demand periods.
2Productivity
If satellite systems multiplex traffic from fixed and mobile terminals on the same beams, then resource allocation efficiency is improved, but service quality deteriorates due to demand variations
Solution Approach 1:
The patent applies different service quality levels to different user types within the same multiplexed beam. Fixed terminals and mobile users receive differentiated resource allocation and QoS treatment based on their specific requirements, allowing efficient resource sharing while maintaining appropriate service quality for each category.
Solution Approach 2:
The system dynamically adjusts allocation parameters for different terminal types. By changing resource distribution parameters based on real-time demand patterns and terminal characteristics, the system achieves efficient multiplexing while preserving service quality through adaptive parameter modification.
3Reliability
If satellite systems implement per-user QoS control, then service quality is improved, but system complexity increases due to multiple user-specific policies
Solution Approach 1:
The patent segments QoS control into hierarchical levels, implementing per-user quality control through structured policy frameworks. By organizing user-specific policies in a segmented, hierarchical manner, the system maintains high service quality while reducing the operational complexity of managing multiple individual policies.

AI summary
Methods, systems, and devices are described for providing network access services to mobile users via multi-user network access terminals over a multi-beam satellite system. Quality-of-service (QoS) is controlled for the mobile devices at a per-user level according to user-specific traffic policies. Mobile users may be provisioned on the satellite system according to a set of traffic policies based on their service level agreement (SLA). System resources of the satellite may be allocated to mobile users based on the demand of each mobile user and the set of traffic polices associated with each mobile user, regardless of which multi-user network access terminal is used to access the system. Dynamic multiplexing of traffic from fixed terminals and mobile users on the same satellite beam can take advantage of statistical multiplexing of large numbers of users and on different usage patterns between fixed terminals and mobile users.
