Network Slice Creation via Hierarchical Template Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network slice deployment process is inefficient due to the need for extensive manual input of deployment information, leading to low efficiency and a high error rate.
Innovation Solution
The method divides the network slice into four levels (data center-level, slice-level, NS-level, and VNF-level) and pre-stores VNFD information in a database, allowing automatic creation of network slices by entering basic name information, reducing manual work and increasing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual deployment information input is used for network slice creation, then deployment flexibility and customization are improved, but deployment efficiency and time consumption deteriorate
Solution Approach 1:
The patent pre-configures deployment templates with common network slice parameters, NS information, VNF information, and VNFD information before deployment is needed. When a network slice needs to be deployed, the system automatically selects and fills these pre-configured templates based on the slice type, eliminating the need for manual input of routine deployment information while maintaining the ability to customize specific parameters.
Solution Approach 2:
The patent creates and stores deployment templates that capture standardized deployment configurations for different network slice types. These templates serve as reusable copies of deployment information that can be automatically instantiated multiple times, reducing repetitive manual work while preserving deployment flexibility through template selection and parameter customization.
2Manufacturing precision
If manual network slice deployment is performed, then deployment accuracy and error control are improved, but time consumption and operational complexity increase
Solution Approach 1:
The patent implements automatic validation mechanisms that check deployment parameters against predefined rules and constraints. The system provides feedback on parameter validity, configuration consistency, and resource availability, automatically correcting errors or alerting operators before deployment execution. This automated feedback loop maintains deployment accuracy while significantly reducing the time required for manual verification.
Solution Approach 2:
The system automatically performs deployment information validation, template selection, and parameter configuration based on the specified network slice type. The automated system serves itself by retrieving pre-configured deployment information, validating parameters, and executing deployment without requiring manual intervention for routine checks, thereby reducing both time consumption and operational complexity while maintaining accuracy through automated validation rules.
3Ease of operation
If extensive manual input is required for network slice deployment, then deployment control and customization are improved, but operational complexity and error rate increase
Solution Approach 1:
The patent segments the network slice deployment process into distinct hierarchical levels: slice-level parameters, NS-level parameters, VNF-level parameters, and VNFD-level parameters. Each level has its own deployment template and validation rules. This segmentation allows operators to control deployment at the appropriate level of abstraction without being overwhelmed by the entire configuration, reducing operational complexity while maintaining precise control over each deployment aspect.
Solution Approach 2:
The patent creates universal deployment templates that can be applied across multiple network slice types with different levels of customization. The same template framework serves multiple functions: storing pre-configured parameters, validating input data, guiding the deployment process, and generating deployment configurations. This multi-functional template system reduces operational complexity by providing a unified interface while maintaining the ability to control deployment specifics for different slice types.
