Network Slice Management Through Function-Level Performance Metrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to provide a comprehensive evaluation of individual network slices when multiple slices are constructed on a single device, as the combined evaluation index values do not accurately reflect the performance of each slice.
Innovation Solution
A computer system and method that acquires operation information for each network function within a network slice and derives evaluation index values for both individual functions and the network slice, enabling effective management of network slices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple network slices are constructed on one device to improve resource utilization efficiency, then resource utilization efficiency is improved, but the ability to evaluate individual network slice performance deteriorates because only combined evaluation index values per device are available
Solution Approach 1:
The patent segments the combined evaluation index value into individual evaluation index values for each network function within the network slice. By dividing the overall device-level metric into function-specific metrics, the system enables precise evaluation of individual network slice performance while maintaining the resource efficiency benefits of multi-slice construction on single devices.
Solution Approach 2:
The patent introduces management information as an intermediary that bridges the gap between device-level combined metrics and network slice-specific performance evaluation. This intermediary layer processes and transforms the combined evaluation index values into disaggregated metrics for individual network functions, enabling accurate slice-level assessment without requiring separate physical devices.
2Ease of operation
If evaluation index values are aggregated at device level to simplify management, then management complexity is reduced, but the precision of network slice performance evaluation deteriorates
Solution Approach 1:
The patent segments the aggregated device-level evaluation index into discrete components corresponding to individual network functions. This segmentation allows the system to maintain simplified device-level management while simultaneously providing access to detailed function-level metrics for precise network slice performance evaluation when needed.
Solution Approach 2:
The patent implements a dynamic evaluation system that can adapt between aggregated and disaggregated views of performance metrics. The system dynamically determines the appropriate level of metric detail based on management needs, providing both simplified aggregated views for high-level management and detailed segmented views for precise network slice evaluation.

AI summary
A network operating system (NOS) acquires, for a plurality of network functions that achieve a network slice constructed on a mobile wireless communication network, information on an operation of each network function which is measured by one or more apparatus configured to provide at least a part of the plurality of network functions. The NOS derives an evaluation index value of each of the plurality of network functions based on the information on the operation of each of the plurality of network functions, and derives an evaluation index value of the network slice based on the evaluation index values of the plurality of network functions.
