Model-Driven Non-RT RIC for O-RAN Management

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current Open Radio Access Network (O-RAN) management and orchestration in 5G networks lack a flexible Non-Real Time (Non-RT) RIC design, with existing solutions being complex and not leveraging model-driven approaches, leading to inflexible and permanent constituents that vary among deployments.

Innovation Solution

A model-driven Non-RT RIC design is implemented, where features of onboarded applications determine the deployment of components during runtime, using a TOSCA-based approach to enable flexibility and dynamic component deployment within the O-RAN Management and Orchestration framework.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a model-driven Non-RT RIC design is implemented, then flexibility and adaptability are improved, but system complexity increases

Engineering Contradiction:

ImproveflexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The Non-RT RIC system is segmented into modular components including service templates, component catalogs, and deployment descriptors. Each service template defines a specific service type with its required components, allowing the system to be built from standardized, reusable modules rather than monolithic structures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system uses parameter-driven deployment where service templates contain configurable parameters that determine which components are instantiated and how they are configured. This allows the same template to produce different service instances with varying degrees of complexity based on operational requirements.

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If existing Open Source solutions are used, then implementation is simplified, but flexibility and adaptability deteriorate

Engineering Contradiction:

Improveimplementation easeVSAvoidflexibility

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The service template approach provides a universal framework that can accommodate multiple service types and configurations through a single standardized mechanism. The same template system can define different services with different components, making the system universally applicable while maintaining flexibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables dynamic service instantiation where services can be deployed, modified, or removed at runtime based on changing requirements. The component catalog and service templates work together to allow dynamic assembly of service instances without requiring system-wide reconfiguration.

Inventive Principle:

Principle #15Dynamics
