Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack the capability to perform continuous quality of experience (QoE) measurement for multicast broadcast service (MBS) when a user equipment (UE) is in mobile situations, particularly in RRC idle or inactive states.
Innovation Solution
A method and apparatus for QoE measurement in MBS that involves determining control actions based on configuration information, including pausing, resuming, deleting, or establishing QoE measurements by a terminal or a base station, utilizing QoE configuration information to manage QoE measurement continuity during UE mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional QoE measurement mechanisms are used, then QoE measurement can be performed in RRC connected state, but continuous QoE measurement cannot be maintained when UE is in RRC idle or inactive state during mobility
Solution Approach 1:
The patent extends QoE measurement capability to support multiple RRC states (connected, inactive, and idle states) through a unified measurement framework. The terminal device performs QoE measurement across different RRC states using the same measurement object and procedure, enabling continuous QoE assessment regardless of the terminal's RRC state during mobility procedures.
Solution Approach 2:
The patent introduces dynamic state transition handling where the terminal device can seamlessly transition between different RRC states while maintaining QoE measurement continuity. The measurement process adapts to state changes by preserving measurement context and configuration across state transitions, ensuring uninterrupted QoE data collection during mobility.
2Reliability
If QoE measurement is performed continuously during mobility, then measurement continuity is improved, but the complexity of managing QoE configuration across base station transitions increases
Solution Approach 1:
The patent implements preliminary QoE configuration setup where the terminal device receives and stores QoE measurement configuration information before mobility begins. The configuration includes measurement object identifiers and parameters that are preserved and reused during base station transitions, eliminating the need for complex real-time reconfiguration and simplifying the handover process.
Solution Approach 2:
The patent introduces configuration information as an intermediary element that carries QoE measurement parameters between the network and terminal device. This configuration information acts as a mediator that preserves measurement context across base station transitions, reducing the complexity of direct configuration management during mobility by providing a stable reference that persists through state changes.
