Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In dual connection scenarios, conflicts arise in identification information for quality of experience (QoE) measurement when both the master node (MN) and secondary node (SN) transmit configurations to user equipment (UE) independently, leading to inconsistencies.

Innovation Solution

The method involves the master node transmitting first identification information to the secondary node, which includes available QoE measurement information, and the secondary node receiving and selecting appropriate identification information to avoid conflicts, ensuring consistent QoE measurement configurations.

Engineering Contradictions & Design Principles

1Adaptability or versatility

If both master node and secondary node transmit QoE configuration to UE independently, then each node can configure QoE measurements autonomously, but conflicts arise in identification information for QoE measurement

Engineering Contradiction:

Improveautonomous QoE configuration capabilityVSAvoidconsistency of QoE measurement identification

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The master node performs preliminary action by determining available QoE measurement identification information and notifying the secondary node before the secondary node configures QoE measurements. This advance notification ensures the secondary node receives and stores the identification information in advance, preventing conflicts when both nodes independently configure QoE measurements to the UE.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The master node provides feedback to the secondary node by notifying it of the available QoE measurement identification information. This feedback mechanism ensures the secondary node has accurate and consistent identification information, resolving the contradiction between autonomous configuration capability and measurement consistency.

Inventive Principle:

Principle #23Feedback

2Reliability

If master node determines and notifies QoE measurement identification information to secondary node, then identification conflicts are avoided, but additional signaling overhead is introduced

Engineering Contradiction:

Improveconsistency of QoE measurement identificationVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The QoE configuration process is segmented into distinct phases: the master node determines identification information, notifies the secondary node, and the secondary node stores and uses this information for configuration. This segmentation allows the identification information to be transmitted once and reused, reducing redundant signaling compared to continuous verification mechanisms.

Inventive Principle:

Principle #1Segmentation

3Reliability

If secondary node stores received QoE measurement identification information, then identification conflicts are prevented, but memory resources are consumed

Engineering Contradiction:

Improveavoidance of identification conflictsVSAvoidmemory resources

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The secondary node applies local quality by storing QoE measurement identification information locally in its memory. This local storage ensures the node has immediate access to the correct identification information when configuring QoE measurements, preventing conflicts without requiring continuous communication with the master node.

Inventive Principle:

Principle #3Local quality
