Solution Overview

Problem

In the context of 5G mobile communication, the conventional drive test methods for wireless network diagnostics suffer from low accuracy due to varying measurement configurations of user equipment (UE) connected to the same base station, leading to inconsistent cell radio signal analysis.

Innovation Solution

A method is introduced where a base station receives configuration information from a core network or OAM system, generates a uniform measurement configuration message for UE, ensuring all measurements are based on the same beam configuration information, thereby improving analysis accuracy by standardizing the measurement results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different measurement configurations are used for UE connected to the same base station, then the system can support diverse measurement requirements, but the accuracy of cell radio signal analysis deteriorates due to inconsistent measurement bases

Engineering Contradiction:

Solution Approach 1:

The patent applies homogeneity by ensuring that all UE connected to the same base station use identical beam configuration information for MDT measurements. The base station generates a uniform measurement configuration message that is sent to all UE, making the measurement configurations homogeneous across different users. This resolves the contradiction by prioritizing measurement consistency (accuracy) while still allowing the system to serve multiple users through the same standardized configuration approach.

Inventive Principle:
Principle #33Homogeneity

2Measurement precision

If uniform measurement configurations are enforced for all UE, then analysis accuracy improves, but the system's ability to handle diverse measurement requirements deteriorates

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies segmentation by dividing the measurement configuration process into two levels: a uniform base configuration generated by the base station for all UE, and potential user-specific adjustments that can be made within the framework. The base station segments the configuration generation task, creating a standardized template that ensures consistency while allowing for individual customization if needed, thus balancing accuracy requirements with adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies universality by designing a measurement configuration message structure that serves all UE connected to a base station. The same configuration template can be universally applied to multiple users, making the system efficient and consistent. This universal approach improves analysis accuracy while the configuration's flexibility allows it to accommodate different measurement scenarios, achieving multi-functionality.

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

AI summary

Embodiments of this application disclose a minimization of drive tests (MDT) configuration method, to improve accuracy of a cell measurement result. The method in the embodiments of this application includes: receiving, by a base station, MDT configuration information sent by a core network or an operation, administration, and maintenance (OAM) network management system, where the MDT configuration information includes first beam configuration information; and sending, by the base station, an MDT measurement configuration message to UE based on the MDT configuration information, where the MDT measurement configuration message includes second beam configuration information, and the second beam configuration information is the same as the first beam configuration information or the second beam configuration information is configuration information obtained after the first beam configuration information is processed.
