QoE Identifier Mapping for Low-Overhead Wireless Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient mechanisms for quality of experience (QoE) measurements, particularly in managing and reporting application-level QoE configurations between user equipment (UE) and base stations, which hinders network optimization and user satisfaction.
Innovation Solution
Implementing an access stratum identifier as a shortened version of an application-level identifier for QoE configurations, enabling UE and base stations to exchange QoE reports and measurements, and forwarding these to an operations, administration, and management (OAM) server for network optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full application-level identifiers are used in QoE configurations and reports, then QoE measurement accuracy and traceability are improved, but signaling overhead and network resource consumption increase
Solution Approach 1:
The solution segments the identifier handling by introducing a dedicated access stratum identifier that operates independently from the full application-level identifier. This segmentation allows the access stratum to use compact identifiers for routine QoE reporting while the application layer maintains the complete identifiers for traceability, thus reducing signaling overhead without compromising measurement accuracy.
Solution Approach 2:
The access stratum identifier acts as an intermediary between the application layer and the radio access network. It mediates the transmission of QoE reports by providing a condensed reference that the base station can use to identify and forward reports to the appropriate application layer entity, thereby reducing the amount of data transmitted over the air interface while maintaining full traceability capability.
2Adaptability or versatility
If QoE reports are forwarded to OAM servers for every application-level configuration, then network optimization capability is improved, but base station processing complexity and resource usage increase
Solution Approach 1:
The architecture segments the QoE reporting workflow into two distinct paths: access stratum-level reporting using compact identifiers for routine monitoring, and application-layer forwarding for comprehensive analysis. This segmentation allows the base station to handle simplified access stratum reports without the full burden of processing complete application-level configurations, reducing processing complexity while maintaining optimization capability.
Solution Approach 2:
The access stratum identifier serves as an intermediary mechanism that enables the base station to efficiently route QoE reports to OAM servers without requiring deep processing of application-level configurations at the base station. The base station uses the compact access stratum identifier to identify the corresponding application-level configuration and forward only necessary information, thereby reducing processing complexity while preserving network optimization capabilities.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a quality of experience (QoE) configuration message that includes an access stratum identifier, wherein the access stratum identifier is a shortened version of an application-level identifier associated with one or more QoE configurations. The UE may obtain application layer QoE measurements. The UE may transmit, to the base station, a QoE report that includes the application layer QoE measurements, wherein the QoE report includes the access stratum identifier to indicate that the QoE report is associated with the application-level identifier or the one or more QoE configurations. Numerous other aspects are described.
