Solution Overview

Problem

Existing drive tests in wireless communication systems often fail to efficiently manage and minimize management-based and signaling-based measurements, leading to unnecessary overlap or delayed configuration, which affects the effectiveness of network optimization.

Innovation Solution

A method and apparatus for minimizing drive tests (MDT) by utilizing indication information to differentiate between management-based and signaling-based logged measurement configurations across different access technologies, allowing for precise management of MDT measurements and preventing overlap or delayed configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If management-based MDT measurements are performed without differentiation from signaling-based measurements, then measurement coverage is increased, but measurement overlap and configuration delays occur

Engineering Contradiction:
Improvemeasurement coverageVSAvoidconfiguration delay
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The patent segments MDT measurements into two distinct types: management-based MDT and signaling-based MDT. This segmentation is achieved through separate configuration indicators (first indication information for management-based, second indication information for signaling-based) that allow the network device to independently manage and configure each measurement type, preventing overlap and configuration delays while maintaining comprehensive measurement coverage.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If MDT measurements are performed across all access technologies without specific indication, then measurement versatility is improved, but measurement precision and targeted configuration deteriorate

Engineering Contradiction:
Improvemeasurement versatilityVSAvoidmeasurement precision
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent applies local quality by introducing access technology indication information that specifies which access technology (EUTRA, NR, or both) each MDT measurement type should operate on. This allows management-based and signaling-based MDT measurements to be precisely targeted at specific access technologies, improving measurement precision while maintaining versatility across multiple access technologies through the combination of different indication possibilities.

Inventive Principle:
Principle #3Local quality

AI summary

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present invention provides a method and a device for minimization of drive tests measurement enhancement. The method includes receiving at least one indication information of first indication information, second indication information and third indication information from a first node, wherein the first indication information indicates whether a MDT measurement result exists, the second indication information indicates whether a MDT measurement configuration exists, and the third indication information indicates an access network technology. The present invention can prevent the management-based minimization of drive tests from covering the signaling-based minimization of drive tests, or the management-based minimization of drive tests can be configured in time.
