Solution Overview

Problem

In dual-card terminals, configuring minimization of drive-test (MDT) for two registered cells results in resource wastage due to duplicate configurations, increasing network signaling load.

Innovation Solution

A communications device with integrated UEs shares or exchanges MDT configuration information, allowing a single configuration to perform MDT measurements and record results for both UEs, reducing the need for duplicate configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If MDT configuration is performed for both UE 1 and UE 2 separately in a dual-card terminal, then measurement coverage is improved, but network signaling load increases and resources are wasted

Engineering Contradiction:
Improvemeasurement coverageVSAvoidnetwork signaling
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges the MDT configuration process for UE 1 and UE 2 into a single unified configuration. The network device sends one MDT configuration message that contains measurement parameters applicable to both UEs, eliminating the need for separate configuration messages and reducing network signaling overhead while maintaining measurement coverage for both UEs

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The MDT configuration message is designed with universal applicability, containing measurement parameters that can be simultaneously used by both UE 1 and UE 2. This multi-functional configuration approach allows a single configuration to serve multiple UEs, optimizing resource utilization and reducing redundant signaling

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If MDT configuration is performed for both UE 1 and UE 2 separately in a dual-card terminal, then measurement accuracy is maintained, but resource utilization deteriorates

Engineering Contradiction:
Improvemeasurement accuracyVSAvoidresource utilization
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent combines the MDT measurement configuration for both UEs into a single operational framework. Both UE 1 and UE 2 execute the same measurement parameters and reporting requirements through one unified configuration, ensuring measurement accuracy is maintained while eliminating redundant configuration processing and improving overall system resource utilization

Inventive Principle:
Principle #5Merging (Combining)
