Solution Overview

Problem

Conventional network optimization through drive tests requires significant human and material resources and relies heavily on expert knowledge, and existing MDT technologies struggle to perform Bluetooth (BT) and Wireless Local Area Network (WLAN) measurements indoors due to lack of core network device configuration capabilities.

Innovation Solution

The core network device sets MDT configuration information for BT/WLAN measurements and sends it to the base station, which determines suitable terminals and configures them to perform these measurements, improving measurement accuracy and reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional drive test methods are used for network optimization, then measurement data can be obtained, but heavy human resource, material resource and fund investments are required

Engineering Contradiction:
Improvenetwork performance measurementVSAvoidhuman and material resources
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent uses terminal devices (mobile phones) to copy the measurement function of expensive drive test instruments. Instead of using specialized DT equipment with professional operators, ordinary terminals perform MDT measurements, creating a virtual copy of the measurement capability that eliminates the need for heavy resource investment while maintaining measurement effectiveness.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent enables terminals to autonomously perform MDT measurements and report data without requiring professional operators. The terminal itself serves as both the measurement instrument and the data collector, eliminating the need for human resource investment in drive test operations and enabling automated network optimization.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If conventional drive test methods are used for network optimization, then network problems can be identified, but very high requirement on experience of network optimization worker is needed

Engineering Contradiction:
Improvenetwork problem detectionVSAvoidoperation complexity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system enables automated MDT configuration and execution where terminals autonomously perform measurements and report data. The core network device automatically configures measurement parameters, selects measurement targets, and collects results without requiring manual intervention by experienced optimization workers, thereby eliminating the high experience requirement while maintaining problem detection capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The core network device pre-configures MDT measurement parameters, measurement targets, and reporting mechanisms before terminals perform measurements. This preliminary configuration automates the complex decision-making process that previously required experienced workers, allowing any operator to execute standardized measurement tasks with consistent results.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If existing MDT technologies are used, then measurements can be performed, but BT and WLAN measurements indoors cannot be performed due to lack of core network device configuration capabilities

Engineering Contradiction:
Improvemeasurement environment coverageVSAvoidmeasurement reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extends MDT measurement capability to multiple network types (LTE, BT, WLAN) and multiple environments (indoor, outdoor) through a unified core network configuration mechanism. The core network device can configure measurement parameters for different radio access technologies and measurement targets, making the MDT system universal across diverse measurement scenarios while maintaining reliable data collection through standardized reporting procedures.

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