QoE Measurement Reporting With Path-Specific Network Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing framework for quality of experience (QoE) measurements in wireless networks, particularly in LTE and NR, does not adequately address the complexities and granular control required for UEs connected to both LTE and NR networks, lacking the necessary flexibility and precision for multi-path connectivity scenarios.
Innovation Solution
Implement methods for performing QoE measurements that include receiving and sending network assistance information (NAI) related to multi-path connectivity features, such as dual connectivity, carrier aggregation, and PDCP duplication, to enhance the granularity and control of QoE reporting.

Engineering Contradiction Analysis
1Measurement precision
If existing QoE measurement framework is used, then basic QoE reporting is achieved, but granularity and control for multi-path connectivity scenarios are insufficient
Solution Approach 1:
The patent segments QoE measurement reporting by introducing path-specific measurement containers that separately report QoE metrics for each connectivity path (e.g., LTE path, NR path). This segmentation enables granular analysis of multi-path scenarios while maintaining a structured, manageable framework through standardized container formats and hierarchical reporting levels.
Solution Approach 2:
The patent adds a new dimension to QoE reporting by introducing path identification parameters and multi-path connectivity indicators alongside traditional QoE metrics. This dimensional expansion allows the framework to distinguish and analyze different connectivity paths without fundamentally redesigning the entire measurement architecture.
2Productivity
If detailed QoE measurement reports with multi-path information are implemented, then network optimization capability is improved, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent implements partial reporting by allowing UEs to selectively include path-specific QoE information based on configuration parameters and current network conditions. Not all QoE metrics are reported for all paths at all times - instead, reporting is tailored to the specific scenario, reducing unnecessary signaling while maintaining optimization capability where needed.
Solution Approach 2:
The patent uses preliminary configuration signaling to establish measurement parameters, path identifiers, and reporting triggers before actual QoE measurement begins. This preliminary setup phase allows the network to define exactly what information should be collected and how, minimizing subsequent signaling overhead during the measurement and reporting phase.

AI summary
Embodiments include methods for a user equipment (UE) to perform quality of experience (QoE) measurements configured by a wireless network. Such methods include receiving, from a radio access network node (RNN) in the wireless network, a QoE measurement configuration for one or more services provided by the UE application layer. Such methods include performing application-layer QoE measurements for the one or more services according to the QoE measurement configuration and sending, to or via the RNN in accordance with QoE measurement configuration, one or more messages comprising: one or more QoE measurement reports comprising results of the QoE measurements; and network assistance information (NAI) related to one or more paths that carry data associated with the one or more services. Other embodiments include complementary methods for RNNs and measurement functions, as well as UEs, RNNs, and measurement functions configured to perform such methods.
