Dual-Connectivity QoE Reporting via SRB-Aware Measurement Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack effective methods for performing quality of experience (QoE) measurement configuration and reporting in standalone (SA) or dual connectivity (DC) scenarios, particularly for enhanced reduced capability (eRedCap) UEs, and there is a need for enhanced capability indication through random access procedures.
Innovation Solution
A method and device that enable a UE to receive configuration information for QoE measurements, perform reporting based on this information, and discard untransmitted reports upon SCG release, using specific signaling radio bearers (SRBs) for QoE reporting in dual connectivity scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If QoE measurement configuration is provided to UE in dual connectivity scenario, then QoE measurement capability is improved, but device complexity increases due to multiple SRB management
Solution Approach 1:
The patent segments QoE measurement configuration by associating each QoE measurement with a specific SRB identifier. This allows the UE to manage multiple QoE measurements independently, each tied to a specific signaling radio bearer (SRB0-SRB5), thereby reducing the complexity of managing QoE configurations in dual connectivity scenarios where multiple bearers exist.
Solution Approach 2:
The patent introduces a new dimension to QoE measurement configuration by adding SRB identifier association. Instead of managing QoE measurements in a single dimension, the system now operates in two dimensions: measurement parameters and bearer identification. This dimensional expansion enables precise control over which SRB carries which QoE report, simplifying management in complex dual connectivity environments.
2Productivity
If SCG is released in dual connectivity, then network resource allocation is improved, but QoE report transmission reliability deteriorates due to untransmitted reports
Solution Approach 1:
The patent implements preliminary action by requiring the UE to discard QoE reports that have not been transmitted when the SCG is released. This proactive measure prevents potential transmission failures and ensures network resources are not wasted on unreliably delivered reports, thereby maintaining both resource allocation efficiency and transmission reliability.
Solution Approach 2:
The patent converts the potential harm of untransmitted QoE reports during SCG release into a benefit by implementing a discard mechanism. This ensures that the network receives accurate, confirmed QoE data rather than risking transmission failures, thus improving overall system reliability while maintaining efficient resource allocation.
3Adaptability or versatility
If eRedCap UE capability indication is enhanced, then device adaptability is improved, but signaling overhead increases
Solution Approach 1:
The patent applies universality by enabling the same QoE measurement configuration mechanism to serve multiple functions: it supports both regular UEs and eRedCap UEs, and can indicate capability information while managing QoE reports. This multi-functionality enhances device adaptability without requiring separate signaling paths, thereby avoiding additional signaling overhead.
