Solution Overview

Problem

Current communication networks face challenges in managing network slices and providing telecommunication services across 5G and non-5G management entities, lacking effective interfaces and functionalities to support advanced service offerings like CaaS, NSaaS, NSSaaS, and IaaS, which require new network management functions and interfaces for efficient resource allocation and service orchestration.

Innovation Solution

The development of techniques for creating and managing interfaces between network management functions (MFs) to enable the provisioning of telecommunication services, including the creation of SMF to SMF, SMF to network MF, and network MF to other MF interfaces, allowing for template requests, service requirement management, and resource management, thereby facilitating the interaction between 5G and non-5G management entities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If new network management functions and interfaces are introduced to support 5G service offerings (CaaS, NSaaS, NSSaaS, IaaS), then service functionality and adaptability are improved, but system complexity increases

Engineering Contradiction:
Improveservice functionalityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments network management into multiple specialized functions: Service Management Function (SMF) for service-level operations, Network Management Function (NMF) for network-resource operations, and Slice Management Function (Slice MF) for slice-specific operations. This segmentation allows each function to be optimized independently while maintaining overall system adaptability for multiple service offerings (CaaS, NSaaS, NSSaaS, IaaS).

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary Slice MF that acts as a bridge between the SMF and NMF, and between 5G and non-5G management entities. This intermediary handles interface conversion and protocol translation, enabling complex multi-service functionality while shielding underlying system complexity from end users and simplifying integration.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If interface conversion and protocol translation capabilities are added to enable interaction between 5G and non-5G entities, then interoperability and adaptability improve, but device complexity increases

Engineering Contradiction:
ImproveinteroperabilityVSAvoidentity complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The Slice MF is designed with universal capabilities to handle multiple service types (CaaS, NSaaS, NSSaaS, IaaS) and multiple protocol conversions simultaneously. This multi-functional design consolidates what would otherwise require separate specialized entities for each service type and protocol combination, reducing overall system complexity while maintaining broad interoperability.

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

Solution Approach 2:

The Slice MF serves as an intermediary layer between 5G and non-5G management entities, performing protocol translation and interface conversion. This mediator approach isolates complexity within a single entity rather than requiring complex integration logic in multiple entities, thereby improving interoperability while containing complexity growth.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple management planes (CP, UP, MP) and network slices are implemented to provide dynamic service capabilities, then service versatility improves, but operational complexity increases

Engineering Contradiction:
Improveservice versatilityVSAvoidoperational complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent divides network management across three distinct planes: Control Plane (CP) for signaling and control functions, User Plane (UP) for data forwarding, and Management Plane (MP) for resource and service management. This segmentation allows each plane to operate independently with specialized functions, improving service versatility while making operations more manageable through clear separation of concerns.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces the management plane as an additional operational dimension separate from control and user planes. This dimensional separation provides a new layer for service orchestration and resource management, enabling complex multi-service operations to be managed through dedicated management procedures rather than complicating the control and user plane operations.

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

4Productivity

If new service offering interfaces (template request, service requirement, resource management) are created, then service provisioning capability improves, but interface complexity increases

Engineering Contradiction:
Improveservice provisioning capabilityVSAvoidinterface complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments service provisioning interfaces into distinct types: template request interfaces for service model definition, service requirement interfaces for customer-specific configurations, and resource management interfaces for network resource allocation. This segmentation allows each interface type to be optimized for its specific purpose, improving provisioning capability for different service scenarios while managing complexity through clear interface categorization.

Inventive Principle:
Principle #1Segmentation
