Solution Overview

Problem

The existing NFV systems face a low degree of operation and maintenance automation, particularly in scenarios involving multiple administrative domains, lacking effective mechanisms for closed-loop automation and requiring manual intervention for coordination between NFVOs.

Innovation Solution

A communication method is introduced where NFVOs in different administrative domains subscribe to and analyze analysis and prediction information using AI-driven data analysis modules, enabling automated management operations based on health reports and empirical models to enhance life cycle management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If NFVOs in multiple administrative domains manually coordinate management operations, then system reliability is maintained through human oversight, but operation and maintenance automation degree remains low and manual intervention is required

Engineering Contradiction:
Improveoperation and maintenance automationVSAvoidsystem reliability
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the first NFVO subscribes to analysis reports from the second NFVO, receives automated analysis results, and uses this feedback to trigger coordinated management operations. This closed-loop feedback system replaces manual coordination while maintaining system reliability through automated decision-making based on real-time analysis data.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an analysis report as an intermediary carrier that transmits operational status and analysis results between NFVOs in different administrative domains. This intermediary mechanism enables automated communication and coordination without requiring direct manual intervention between system operators.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If manual coordination between NFVOs is used, then complex cross-domain operations can be carefully managed, but productivity and operational efficiency decrease due to manual intervention requirements

Engineering Contradiction:
Improveoperational efficiencyVSAvoidcoordination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent enables NFVOs to autonomously subscribe to and receive analysis reports from other administrative domains, and automatically trigger management operations based on received reports. This self-service mechanism eliminates the need for manual coordination while handling complex cross-domain operations, thereby improving productivity without increasing operational complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The first NFVO subscribes to analysis reports in advance from the second NFVO, preparing the system for automated coordination. This preliminary subscription setup enables rapid response to operational events without requiring ad-hoc manual intervention, thus improving operational efficiency while managing complexity through pre-configured automated processes.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If comprehensive monitoring and analysis of nested NS instances are implemented, then measurement precision of operational status is improved, but device complexity increases due to additional subscription and analysis mechanisms

Engineering Contradiction:
Improvemonitoring accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the monitoring and analysis functions by having the second NFVO specifically responsible for analyzing nested NS instances and generating analysis reports, while the first NFVO subscribes to and uses these reports. This segmentation allows comprehensive monitoring with high measurement precision while distributing system complexity across different NFVO components rather than concentrating it in one system.

Inventive Principle:
Principle #1Segmentation
