QoE Measurement Report Size Control in RRC Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3GPP New Radio (NR) systems lack efficient control mechanisms for Quality of Experience (QoE) measurement reporting, which is essential for optimizing network performance and user experience, especially during RAN overload conditions where QoE reports need to be stored and transmitted efficiently.
Innovation Solution
Introduction of RRC messages for requesting and transferring the size of stored QoE reports, provision of QoE reporting policy in a QoE resume indication, and rules for creating and transmitting QoE reports in the MeasurementReportAppLayer message to manage report handling and segmentation effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QoE measurement reports are stored in the RRC buffer during RAN overload, then the reports are preserved for later transmission, but the buffer size and memory requirements increase
Solution Approach 1:
The patent segments QoE measurement reports into multiple parts or chunks that can be stored and transmitted separately. The RRC buffer manages these segmented reports efficiently, allowing the system to preserve QoE data without requiring a single large buffer, thus reducing overall memory requirements while maintaining reliability.
Solution Approach 2:
The patent implements preliminary actions by pre-allocating buffer space and establishing buffer management policies before QoE reports need to be stored. This allows the system to efficiently handle report storage during RAN overload without requiring excessive buffer capacity, as the buffer structure is already optimized in advance.
2Loss of time
If QoE reports are transmitted during RAN overload, then real-time monitoring is improved, but network congestion increases
Solution Approach 1:
The patent implements dynamic transmission strategies where the timing and priority of QoE report transmission are adjusted based on current network conditions. During RAN overload, the system dynamically prioritizes critical reports while deferring less urgent ones, allowing real-time monitoring to be maintained without exacerbating network congestion.
Solution Approach 2:
The patent employs feedback mechanisms where the network monitors the state of RAN overload and adjusts QoE report transmission accordingly. When congestion is detected, the system receives feedback and modifies transmission behavior, balancing the need for timely report delivery with the need to avoid worsening network conditions.
3Productivity
If selective control of QoE report transmission is implemented, then network resource utilization is optimized, but the complexity of transmission control increases
Solution Approach 1:
The patent introduces an intermediary buffer management layer that handles the complexity of selective transmission control. This intermediary mechanism sits between the QoE measurement function and the transmission function, automating the decision-making process for report transmission and simplifying the overall system architecture while optimizing network resource utilization.
Solution Approach 2:
The patent implements self-service mechanisms where the QoE report transmission system automatically manages its own prioritization and scheduling based on predefined policies and current network conditions. This self-managing approach optimizes network resource utilization without requiring complex external control mechanisms, thereby reducing overall system complexity.

AI summary
Apparatuses, methods, and systems are disclosed for QoE measurement reporting control. One method includes receiving, from a communication network, a first message requesting a size of stored QoE measurement reports in an RRC buffer. The method includes determining, by the communication device, the size of the stored QoE measurement reports in response to the first message and transmitting, to the communication network, a second message including the size of stored QoE measurement reports in the RRC buffer. The method includes receiving, from the communication network, a third message including a configuration to enable resumption of QoE measurement reporting and transmitting, to the communication network, at least one fourth message including at least one QoE measurement report.
