Solution Overview

Problem

Existing communication network management systems struggle to efficiently select and deploy cognitive network functions (CNFs) and machine learning (ML) models that match the network's expected or detected context, especially when multiple vendors and models are involved, lacking mechanisms for context-based selection and standardized information exchange.

Innovation Solution

A cognitive network function and model repository function (CoMReF) and selection function (CoMSeF) are introduced, along with a structured interface (CoMSI) and information model to enable operators to request and select context-specific CNFs and ML models, using standardized metadata to match network requirements with available models.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cognitive network functions and machine learning models from different vendors are deployed, then the versatility and functionality of the network are improved, but the complexity of selecting and managing the appropriate models increases

Engineering Contradiction:
Improvenetwork functionalityVSAvoidmodel selection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary system comprising a model repository function and selection function that acts as a mediator between multiple ML model vendors and the network operator. This intermediary standardizes the information exchange format, centralizes model storage, and automates the selection process based on network context, thereby resolving the complexity issue while maintaining versatility.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a universal interface and standardized information model that can handle multiple ML models from different vendors through a single standardized channel. The selection function serves multiple purposes: storing models, evaluating them against network context, and selecting the optimal model, thereby reducing overall system complexity through multi-functionality.

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

2Measurement precision

If context-based selection mechanisms are implemented, then the precision of model matching is improved, but the information exchange requirements and system complexity increase

Engineering Contradiction:
Improvemodel matching precisionVSAvoidinformation exchange requirements
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent transforms the model selection problem into a parameter-matching problem by defining specific context parameters (network state, performance metrics, operational conditions) and model parameters (input data characteristics, expected output, performance requirements). The selection function compares these parameters systematically to achieve precise matching while standardizing the information exchange format to minimize data loss.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements preliminary action by pre-defining the information model structure, pre-storing ML models with their associated context requirements in the repository, and pre-establishing the selection criteria based on network context parameters. This preliminary preparation reduces the information exchange burden during actual model selection operations.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If automated model selection and deployment is implemented, then the productivity of network management is improved, but the extent of automation required increases system complexity

Engineering Contradiction:
Improvenetwork management efficiencyVSAvoidautomation system complexity
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The patent implements self-service by enabling the selection function to autonomously evaluate network context, query the model repository, select the appropriate ML model, and deploy it without human intervention. The system monitors network conditions and automatically triggers model reselection when context changes, achieving high productivity through self-service automation while keeping the automation logic centralized and manageable.

Inventive Principle:
Principle #25Self-service
