QoE Measurement Policy for UE Buffer Overflow Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of ensuring the integrity of quality of experience (QoE) measurement results is hindered by buffer capacity limitations in user equipment (UE), leading to potential data discard during QoE measurement collection tasks.
Innovation Solution
A method and system that involves determining and sending QoE measurement policies from a first network management node to a second network management node, which then instructs a base station to manage QoE measurement reports at the UE, including discarding, storing, or reporting based on specific policies to maintain report integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the UE stores QoE measurement data in the buffer at access stratum, then the measurement data can be collected and managed, but the buffer capacity is limited and may be full, leading to data discard
Solution Approach 1:
The patent divides the storage location into two segments: access stratum buffer (for temporary storage) and application layer storage (for long-term retention). When the access stratum buffer is full, the system segments the data management by transferring critical measurement data to the application layer, thereby preventing data discard while maintaining buffer efficiency.
Solution Approach 2:
The patent adds a new dimension to the storage architecture by introducing application layer storage as an additional storage layer. This dimensional expansion allows the system to handle more measurement data beyond the capacity of the access stratum buffer alone, ensuring data integrity when the buffer is full.
2Device complexity
If the UE discards partial QoE measurement data when buffer is full, then the buffer capacity limitation is respected, but the integrity of QoE measurement result is compromised
Solution Approach 1:
The patent implements preliminary action by establishing application layer storage capacity before buffer overflow occurs. The system proactively prepares alternative storage locations and establishes data transfer mechanisms in advance, so when the access stratum buffer becomes full, data can be seamlessly transferred to the application layer without loss or requiring complex real-time decision-making.
3Reliability
If the UE stores all QoE measurement data, then the measurement integrity is maintained, but the buffer capacity is exceeded and data must be discarded
Solution Approach 1:
The patent introduces application layer storage as an intermediary between the access stratum buffer and the final data retention requirement. This intermediary layer absorbs excess measurement data when the buffer is full, acting as a buffer-for-buffers that protects data integrity while accommodating quantities exceeding the original buffer capacity.

AI summary
Embodiments of this application disclose a measurement data management method and system, and a related device. The method includes: determining a quality of experience QoE measurement policy; and sending the QoE measurement policy to a second network management node, where the QoE measurement policy is used by a base station under the second network management node to perform a QoE measurement task. In embodiments of this application, a first network management node may send the QoE measurement policy to the base station through the second network management node, and the base station sends the QoE measurement policy to UE, to indicate the UE to manage a QoE measurement report based on the QoE measurement policy. This can ensure integrity of the QoE measurement report reported by the UE.
