Terminal QoE Reporting Routing in MR-DC Access Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a multi-radio dual connectivity (MR-DC) architecture, determining how a terminal device reports quality of experience (QoE) measurement results to the correct access network device is a challenge, especially when multiple access network devices are involved.
Innovation Solution
The terminal device's access stratum receives indication information to determine whether to send QoE measurement results to the master node or secondary node, using trace identifiers, service type information, and other indicators to ensure accurate reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device sends QoE measurement results to multiple access network devices in MR-DC architecture, then the measurement coverage is improved, but the device complexity and processing overhead increase
Solution Approach 1:
The patent introduces an intermediary indication information mechanism that mediates between the terminal device and multiple access network devices. The access stratum receives indication information from the upper layer that specifies which access network device (MN or SN) should receive the QoE measurement result, thereby simplifying the terminal's decision-making process while ensuring reliable reporting to the correct device.
Solution Approach 2:
The patent segments the QoE measurement reporting function by separating the indication information (which access network device to send to) from the actual measurement result. The access stratum handles the indication information to determine the target device, while the upper layer generates the measurement result, creating a clear division of responsibilities that reduces overall system complexity.
2Measurement precision
If the terminal device determines which access network device to send QoE results to using complex criteria, then the measurement precision is improved, but the processing time and complexity increase
Solution Approach 1:
The patent applies preliminary action by having the upper layer pre-determine the target access network device and encode this decision in indication information before the actual measurement result is generated. When the access stratum receives both the indication information and measurement result, it can immediately route the result without performing complex real-time analysis, thus reducing processing time while maintaining precision.
3Adaptability or versatility
If both MN and SN send QoE measurement configuration information to the terminal device, then the adaptability is improved, but the difficulty of detecting and measuring the correct target device increases
Solution Approach 1:
The patent implements feedback by having the access network device that sends the QoE measurement configuration information also receive the indication information from the terminal's upper layer. This creates a feedback loop where the configuration sender is informed of the intended recipient, allowing the system to adaptively route measurement results correctly even when multiple devices are involved in the configuration process.

AI summary
This application provides communication methods and communication apparatuses. One example communication method includes: An receiving, by an access stratum of a terminal device, receives a quality of experience QoE measurement result and first indication information from an upper layer of the access stratum. The access stratum of the terminal device determines, based on the first indication information, to send the QoE measurement result to a master node or a secondary node of the terminal device. Therefore, in this application, the upper layer of the access stratum of the terminal device sends, to the access stratum, the QoE measurement result and the first indication information corresponding to the Qof measurement result, so that the terminal device in the MR DC architecture can send the QoE measurement result to the correct access network device.
