QoE Measurement Report RRC Segmentation During Cell Group Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems face challenges in effectively transmitting Quality of Experience (QoE) measurement reports, particularly during cell group changes, which can lead to incomplete or failed transmissions.
Innovation Solution
The method involves processing control signals to transmit QoE measurement reports using Radio Resource Control (RRC) messages, allowing for RRC segmentation when necessary, ensuring complete reporting even during cell group changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QoE measurement reports are transmitted using standard RRC messages without segmentation support, then the transmission process is simple, but the transmission reliability deteriorates during cell group changes leading to incomplete or failed transmissions
Solution Approach 1:
The patent applies segmentation by dividing the QoE measurement report transmission into multiple segments when the report size exceeds the maximum RRC message size. The segmentation is controlled by the segmentationIndicator field, and each segment is transmitted separately with proper reassembly at the receiver, ensuring complete and reliable transmission even during cell group changes.
2Reliability
If QoE measurement reports are segmented and retransmitted during cell group changes, then transmission completeness is improved, but the transmission time increases
Solution Approach 1:
The patent applies preliminary action by preparing and transmitting the segmentationIndicator and other necessary control information along with the QoE measurement report before actual data transmission. This allows the receiving end to properly reconstruct and process the segmented data, reducing retransmission delays and improving overall transmission efficiency.
3Reliability
If RRC segmentation is enabled for QoE measurement reports, then transmission reliability during cell group changes is improved, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The patent applies local quality by implementing segmentation and reassembly functionality only where needed - specifically at the UE and gNB ends for QoE measurement report transmissions. The segmentationIndicator and related processing are localized to the RRC layer, allowing other parts of the system to operate without modification, thus minimizing overall device complexity while maintaining reliability.
