Hierarchical MBS QoE Configuration for Precise 5G Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3GPP systems do not specify how to configure Quality of Experience (QoE) measurements or RAN Visible QoE measurements for Multicast and Broadcast Services (MBS), which are essential for optimizing network performance and user experience in 5G NR networks.
Innovation Solution
The proposed solution involves configuring and reporting QoE/RVQoE measurements for MBS by indicating a first and second level QoE configuration items, where the first level indicates MBS as a service type and the second level specifies the associated application or service type delivered via MBS, enabling network nodes to manage QoE measurements and adjustments based on these configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QoE measurements are configured for MBS, then network optimization and user experience are enhanced, but the system complexity increases due to lack of standardized configuration mechanisms
Solution Approach 1:
The QoE configuration is segmented into multiple levels: first level for MBS service type identification and second level for specific application/service type details. This segmentation allows standardized configuration mechanisms to handle complex MBS QoE measurements by breaking down the configuration into manageable hierarchical components, resolving the contradiction between enhancing network optimization and reducing configuration complexity.
2Measurement precision
If multiple QoE configuration levels are implemented, then measurement precision for MBS is improved, but the reporting and processing complexity increases
Solution Approach 1:
The configuration is divided into first level (MBS service type) and second level (application/service type) measurements. The wireless device reports both levels, but the network can process them in a structured manner where the first level provides broad categorization and the second level provides detailed metrics. This segmentation improves measurement precision while managing processing complexity through hierarchical organization.
Solution Approach 2:
The patent introduces a hierarchical dimension to QoE configuration by adding a second level of measurement beyond the traditional single level. This dimensional expansion allows for more precise measurements without overwhelming the system, as the hierarchical structure provides a framework for organizing and processing the increased measurement data systematically.
3Adaptability or versatility
If QoE configuration items are added for MBS, then adaptability to service delivery methods is improved, but the configuration data structure becomes more complex
Solution Approach 1:
The configuration data structure is segmented into first level items (MBS service type indicators) and second level items (application/service type specifics). This segmentation maintains adaptability to various service delivery methods while organizing the complexity into a structured hierarchical format that is easier to process and manage.
Solution Approach 2:
The hierarchical QoE configuration structure serves multiple functions: it identifies MBS service types, specifies application details, and enables differentiated measurement reporting. This multi-functionality approach increases adaptability to different service delivery methods while managing data structure complexity through a universal hierarchical framework that can accommodate various service types.
