Multi-Slice Service Management for End-to-End QoS and QoE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3GPP specifications do not support end-to-end management of multi-slice, multi-service-instance communication services, leading to inadequate Quality of Service (QoS) and Quality of Experience (QoE) assurance, particularly in scenarios where network slices and service instances are shared across multiple communication services.
Innovation Solution
A device and method for managing services related to multiple network slices, which includes obtaining and evaluating management data to generate assurance indicators, and performing configuration and reconfiguration to ensure QoS and QoE fulfillment across multiple network slices and service instances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If network slices and service instances are shared across multiple communication services to improve resource utilization, then network resource utilization is improved, but QoS and QoE assurance becomes inadequate
Solution Approach 1:
The patent segments the management of shared network resources by introducing service-specific management entities that track and manage resources allocated to each communication service separately. This allows the system to maintain aggregate resource utilization while ensuring individual service QoS requirements are met through dedicated management oversight.
Solution Approach 2:
The patent applies local quality by implementing service-specific QoS policies and management mechanisms for each communication service that shares network resources. Each service receives customized management attention tailored to its specific QoS requirements, while benefiting from the shared infrastructure.
2Adaptability or versatility
If current 3GPP specifications are used for network slice management, then network slice management is supported, but end-to-end multi-slice communication service management is not supported
Solution Approach 1:
The patent implements a nested management architecture where service-specific management entities are embedded within the existing 3GPP network slice management framework. This nested structure allows end-to-end multi-slice service management to be integrated into the existing specifications while adding the necessary complexity only where required.
Solution Approach 2:
The patent introduces intermediary management entities that act as mediators between the existing 3GPP network slice management functions and the new end-to-end multi-slice service management requirements. These intermediaries translate and coordinate management operations across different service instances.
3Reliability
If management data is fetched at the NSI level to ensure QoS fulfillment, then QoS assurance is improved, but QoE guarantee and accurate management data for shared NSIs are not achieved
Solution Approach 1:
The patent adds another dimension to management data collection by implementing service-level management entities that operate alongside the existing NSI-level management. This creates a multi-dimensional management framework where data is collected both at the network slice instance level and at the communication service level, enabling accurate tracking of shared resources for each specific service.
Data Source
AI summary
The present disclosure relates to systems, devices, and methods for communication services. One method comprises: obtaining first management data for a service from at least one of a plurality of network slices, wherein the first management data comprises one or more of performance management (PM) data for the service, fault management (FM) data for the service, or analytics data of the service; evaluating at least one assurance indicator of the service based on the first management data to generate an evaluation result; and generating second management data based on the evaluation result, wherein the second management data comprises at least one of configuration management (CM) data for modification of the service or at least one of the plurality of network slices.
