Network Slice Template Definition for 5G IoT Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slicing technologies face interoperability and management efficiency issues due to the lack of standardized criteria for defining network slice templates (NST) and generating network slice instances (NSI), leading to challenges in providing tailored network services across different deployment environments and operator requirements.
Innovation Solution
A method and system for defining NST based on the configuration of the network slice generation and management system, involving a server that receives service requirements, identifies hierarchy structures among management units, and allocates NSI accordingly, enabling flexible and automated generation of network slices suitable for various deployment environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slice templates are defined according to each operator's requirements without standardization, then each operator can provide customized network services, but interoperability between different operators and systems deteriorates
Solution Approach 1:
The patent segments the network slice template definition into standardized hierarchical components (service requirements, network slice requirements, network slice instance configuration). This allows customization at each level while maintaining overall standardization, resolving the contradiction between adaptability and interoperability.
Solution Approach 2:
The patent introduces parameter-based configuration where network slice templates define service requirements, network slice requirements, and instance parameters in a standardized format. Operators can customize by modifying parameters within the standardized framework, achieving both customization and interoperability.
2Adaptability or versatility
If manual methods are used to define and generate network slice instances, then flexibility in handling complex operator requirements is improved, but management efficiency and operational costs deteriorate
Solution Approach 1:
The patent implements automated self-service mechanisms where the system automatically generates network slice instances by retrieving standardized templates and configuring parameters based on service requirements. This eliminates manual intervention while maintaining flexibility through parameter-based customization, improving both efficiency and adaptability.
Solution Approach 2:
The patent performs preliminary actions by pre-defining standardized network slice templates with all necessary configuration parameters before actual network slice instantiation. This preparation enables rapid automated generation of network slice instances without manual configuration, improving management efficiency while maintaining flexibility.
3Reliability
If standardized criteria are introduced for defining network slice templates, then interoperability and management efficiency are improved, but adaptability to specific operator requirements and deployment environments deteriorates
Solution Approach 1:
The patent creates a universal network slice template structure that can serve multiple operators and deployment environments. The standardized template includes configurable parameters that adapt to different requirements, making the same template framework universally applicable while maintaining flexibility for specific deployments.
