Solution Overview

Problem

Current SON-based cellular networks rely heavily on manual analysis and empirical methods for network optimization, requiring significant human resources and expert knowledge, and the optimization algorithms triggered by KPIs often fail to accurately reflect network issues, leading to inefficient maintenance and optimization processes.

Innovation Solution

The method involves acquiring and averaging multiple groups of network status parameters and cell control parameters to accurately represent the network's running status, using KPIs and cell measurement parameters to determine the security status of cells, and performing network optimization based on this data, reducing the need for manual intervention and improving algorithm accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual analysis and empirical methods are used for network optimization, then network status can be understood through expert knowledge, but human resource costs and time consumption increase significantly

Engineering Contradiction:
Improvenetwork status understanding accuracyVSAvoidoptimization time consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system enables self-service through automated network optimization. The network management device automatically collects KPI data, determines network status, selects optimization algorithms, and configures parameters without requiring manual expert intervention. This transforms the manual analysis process into an automated self-service system that reduces both time consumption and human resource requirements while maintaining optimization accuracy

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical system of manual expert analysis with an automated information processing system. Instead of relying on human experts to manually analyze network status and determine optimization strategies, the system uses automated data collection, processing, and algorithm selection mechanisms that substitute human mechanical operations with electronic automation, thereby reducing time loss and human resource costs

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If only KPI statistics are used to represent network running status, then data collection is simplified, but the ability to accurately reflect network problems decreases

Engineering Contradiction:
Improvedata collection complexityVSAvoidnetwork problem detection accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the network status representation into multiple dimensions: KPI statistics (first parameter), cell measurement parameters (second parameter), and optionally security parameters (third parameter). This segmentation allows the system to maintain simplified data collection processes while improving problem detection accuracy by analyzing multiple parameter types together, rather than relying on a single comprehensive but complex data structure

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If optimization algorithms are triggered only by KPI thresholds, then the triggering mechanism is simple, but the accuracy of identifying actual network issues decreases

Engineering Contradiction:
Improvealgorithm triggering simplicityVSAvoidnetwork issue identification accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent adds another dimension to the algorithm triggering mechanism by incorporating cell measurement parameters and security parameters alongside KPI statistics. Instead of relying solely on the single dimension of KPI threshold crossing, the system evaluates multiple parameter dimensions simultaneously, enabling more accurate identification of actual network issues while maintaining operational simplicity through automated multi-parameter evaluation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Measurement precision

If multiple network parameters are collected and analyzed, then network status representation accuracy improves, but processing complexity and resource requirements increase

Engineering Contradiction:
Improvenetwork status representation accuracyVSAvoidparameter processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary mechanism in the form of a network management device that acts as a mediator between data collection and optimization execution. This intermediary automatically performs parameter collection, processing, analysis, and algorithm selection, thereby improving network status representation accuracy through multi-parameter analysis while hiding the processing complexity from users and reducing the perceived resource requirements through automated efficiency

Inventive Principle:
Principle #24Intermediary (Mediator)
