Network Slice Margin Sharing and QoS Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When network slices are provided by multiple infrastructure providers, it is unclear how to configure subslices to satisfy service requirements, leading to inefficient resource use and potential failure to meet service targets, especially when high QoS is required in specific subslices.
Innovation Solution
A communication system that includes a temporary configuration unit, a measurement unit, a sharing unit, and an adjustment unit to temporarily set target values, measure and share margins among subslices, and adjust QoS classes to ensure service requirements are met across multiple subslices while optimizing resource use.

Engineering Contradiction Analysis
1Ease of operation
If target values are distributed equally among subslices, then the configuration process is simple, but service requirements cannot be satisfied when high QoS is needed in specific subslices
Solution Approach 1:
The patent implements dynamic adjustment of target values and QoS classes based on real-time margin measurements. The system transitions from static equal distribution to dynamic optimization where target values are continuously adjusted according to actual performance data, allowing the system to adapt to changing service requirements while maintaining operational simplicity through automated control.
Solution Approach 2:
The measurement unit continuously monitors actual delay values and calculates margins relative to target values. This feedback mechanism enables the adjustment unit to identify which subslices are meeting requirements and which need optimization, allowing targeted adjustments that satisfy service requirements without requiring complex manual configuration.
2Reliability
If high QoS class is configured in specific subslices to meet service requirements, then service requirement satisfaction is improved, but resource efficiency deteriorates
Solution Approach 1:
The patent applies local quality optimization by configuring QoS classes and target values specifically for each subslice based on its actual margin performance. Instead of applying uniform high QoS across all subslices, the system identifies which subslices have sufficient margins and applies appropriate QoS classes locally, optimizing resource allocation to meet service requirements only where necessary.
Solution Approach 2:
The system dynamically changes QoS class parameters and target value parameters based on measured margins. When a subslice has a large margin, the system can relax QoS requirements and use lower QoS classes, thereby improving resource efficiency. When margins are tight, the system automatically adjusts parameters to meet service requirements, creating an optimal balance between reliability and productivity.
3Reliability
If closed-loop control is implemented in each infrastructure provider's controller, then service requirement satisfaction is improved, but system complexity increases
Solution Approach 1:
The patent segments the control function by introducing a centralized controller that operates independently from individual infrastructure provider controllers. This segmentation allows each provider's controller to remain relatively simple while the centralized controller handles the complex coordination, margin measurement, and optimization across the entire slice, distributing complexity appropriately throughout the system architecture.

AI summary
There is provided a communication system for controlling a slice including a plurality of subslices. The system includes a temporary configuration unit configured to temporarily configure, for each subslice, a target value related to a service requirement, a measurement unit configured to acquire, in each subslice, a measurement value related to the service requirement for each QoS class and measure a margin, with respect to the target value, of the measurement value, a sharing unit configured to share the margin among the plurality of subslices, and an adjustment unit configured to smooth the margin among the plurality of subslices while satisfying the service requirement for the slice and configure, for each subslice, the target value and the QoS class corresponding to the margin after smoothing.
