MR-DC Terminal QoE Reporting to the Correct Access Node
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a multi-radio dual connectivity (MR-DC) architecture, there is a challenge in determining how a terminal device reports Quality of Experience (QoE) measurement results to the correct access network device, as both the master node (MN) and secondary node (SN) may send measurement configuration information, leading to ambiguity in reporting.
Innovation Solution
The terminal device is equipped with a method to determine and report QoE measurement results to the correct access network device by negotiating with both the MN and SN, ensuring clear communication pathways for QoE measurement configuration and result reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both MN and SN send measurement configuration information to the terminal device, then the terminal device can perform QoE measurement for different services, but it becomes ambiguous which access network device should receive the QoE measurement result
Solution Approach 1:
The patent introduces an identifier (such as a node ID or configuration index) as an intermediary element within the measurement configuration information. This identifier acts as a mediator that links the measurement configuration from a specific access network device (MN or SN) to the corresponding QoE measurement result, enabling the terminal device to correctly identify and report results to the appropriate device without ambiguity
Solution Approach 2:
The patent segments the QoE measurement reporting process by associating different measurement configurations with distinct identifiers. Each access network device's configuration is uniquely marked, allowing the terminal device to segment and route measurement results to the correct destination based on the identifier matching
2Reliability
If the terminal device reports QoE measurement result to the wrong access network device, then the measurement result cannot be used for network optimization, but adding complex routing logic increases terminal device complexity
Solution Approach 1:
The identifier serves as a simple intermediary that the terminal device uses to match measurement configurations with reporting destinations. This approach maintains low terminal device complexity by using straightforward identifier matching rather than complex routing logic, while ensuring reliable and accurate reporting to the correct access network device
3Adaptability or versatility
If the terminal device stores multiple QoE measurement configuration information from different access network devices, then it can perform comprehensive QoE measurement, but the storage and management overhead increases
Solution Approach 1:
The patent uses lightweight identifier copies within the measurement configuration information rather than storing complete device identities or complex routing data. This copying approach enables comprehensive QoE measurement coverage across multiple access network devices while minimizing storage overhead by using compact, reusable identifier elements

AI summary
This application provides a communication method and a communication apparatus, to enable a terminal device in an MR-DC architecture to send a QoE measurement result to a correct access network device. The communication method includes: 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 QoE measurement result, so that the access stratum can determine, based on the first indication information, to send the QoE measurement result to the master node or the secondary node of the terminal device, and thus the terminal device in the MR-DC architecture can send the QoE measurement result to the correct access network device.
