Solution Overview

Problem

Current communication systems face inefficiencies in data collection during Minimisation of Drive Tests (MDT) jobs, where separate sets of measurements are collected and processed separately, leading to high processing requirements and potential loss of useful data due to the need for correlation and filtering at the Trace Collection Entity (TCE).

Innovation Solution

Implementing a method where primary and secondary measurements are intelligently collected and sent together by radio network elements or user equipment, with secondary measurements only being reported if associated primary measurement data is available, and additional information like timestamps or cell identities is included to facilitate efficient data association and reduction of unnecessary data processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If separate sets of measurements are collected and processed separately, then complete measurement data is obtained, but processing requirements and data loss increase

Engineering Contradiction:
Improvedata lossVSAvoidprocessing requirements
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines primary and secondary measurements into a single integrated data structure (MDT report) that is collected and processed together. This merging eliminates the need for separate collection and processing of measurement sets, reducing processing requirements at the TCE while preventing data loss through proper association of all measurement data in one unified record.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If all measurements are collected and sent, then complete data is available, but data volume and processing load increase

Engineering Contradiction:
Improvedata completenessVSAvoidprocessing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent extracts and identifies primary measurements that serve as key identifiers, with secondary measurements being conditionally collected based on the availability of their associated primary measurements. This extraction approach ensures data completeness for critical measurements while reducing overall data volume by not collecting secondary measurements when their primary counterparts are unavailable, thereby improving processing efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

3Loss of information

If secondary measurements are always collected, then all possible data is captured, but unnecessary data processing increases

Engineering Contradiction:
Improveuseful data retentionVSAvoidprocessing energy
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent performs preliminary checking to determine whether primary measurement data is available before collecting and processing secondary measurements. This preliminary action prevents unnecessary collection and processing of secondary measurements when their associated primary measurements are not available, thereby retaining useful data while reducing processing energy consumption at the TCE.

Inventive Principle:
Principle #10Preliminary action
