Satellite Backhaul QoS Conversion Table for Base Station Priority Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems using satellite backhaul links, existing methods struggle to effectively convert quality of service (QoS) indicators between different communication sections while preventing interference between base stations, leading to issues like data stagnation due to priority conflicts.
Innovation Solution
A satellite communication device that includes a storage unit for a conversion table and a quality of service indicator updating unit. The updating unit evaluates the quality of service for each indicator and updates the priority in the conversion table, ensuring that QoS indicators are converted while minimizing interference between base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple method of converting the quality of service indicator is used, then the conversion process is simple, but priorities of the quality of service among the ground base stations affect one another to cause data with low priority to dwell or stagnate
Solution Approach 1:
The patent segments the QoS indicator conversion process by introducing separate conversion tables for different communication sections (satellite backhaul link and ground base station links). Each conversion table independently manages priority mappings, preventing priority conflicts between base stations while maintaining simple conversion operations within each segment.
Solution Approach 2:
The patent introduces an intermediary conversion table mechanism that acts as a mediator between the satellite backhaul link QoS indicators and the ground base station QoS indicators. This intermediary structure allows independent priority management for each base station, preventing direct interference between their priority assignments while still enabling effective QoS conversion.
2Reliability
If radio resource allocation is used to maintain quality of service, then the quality of service can be maintained, but adjustment for ensuring the quality of service cannot be performed for each base station on the satellite backhaul link that covers a wide area like satellite communication and accommodates a large number of base stations at the same time
Solution Approach 1:
The patent applies local quality by allowing each ground base station to have its own QoS indicator conversion table with customized priority mappings tailored to its specific requirements and service characteristics. This enables independent adjustment of QoS parameters for each base station while maintaining overall system QoS maintenance through the coordinated use of these localized conversion tables.
3Device complexity
If the entire network has a unified quality of service indicator, then the quality of service management is simplified, but the quality of service cannot be adjusted for each individual base station
Solution Approach 1:
The patent segments the unified QoS management into multiple independent conversion tables, each associated with a specific communication section or base station. This segmentation maintains simplicity by keeping each conversion table's management straightforward while enabling individual base station adjustments through the collection of segmented conversion tables.
