Network Slice Control Function Automating Service Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slice management systems require manual configuration and rewriting of service configuration scripts for each deployment site, making them inflexible and difficult to automate, especially when deploying network slices multiple times.
Innovation Solution
A method and apparatus that automatically generate a network slice service configuration scheme based on a pre-designed model, policy, and plan, using registration information of network function entities to automate the network slice creation process, allowing for multiple deployments through a single design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service configuration scripts are manually adjusted for each deployment site, then the network slice can be deployed at different locations, but the process becomes inflexible and requires repeated manual configuration work
Solution Approach 1:
The patent applies preliminary action by pre-defining parameter mappings between service configuration scripts and resource deployment scripts during the network slice template design phase. This allows the system to automatically generate site-specific configurations through parameter substitution rather than manual adjustment, resolving the contradiction between deployment flexibility and configuration complexity
Solution Approach 2:
The patent creates a universal network slice template that can be deployed across multiple sites by establishing a mapping relationship between service configuration parameters and resource deployment parameters. This universal template can adapt to different deployment scenarios through parameter substitution, eliminating the need for manual script rewriting at each site
2Manufacturing precision
If service configuration scripts are rewritten for each deployment, then site-specific requirements can be met, but automation becomes difficult and deployment time increases
Solution Approach 1:
The patent performs preliminary configuration by establishing the mapping relationship between service configuration scripts and resource deployment scripts in advance. During actual deployment, the system automatically substitutes parameters according to this mapping, achieving both configuration accuracy and reduced deployment time without manual intervention
Solution Approach 2:
The patent uses parameter substitution to generate site-specific configuration scripts by copying and adapting the universal network slice template. This copying mechanism with automated parameter replacement ensures configuration accuracy while eliminating repetitive manual work, thus reducing deployment time
3Adaptability or versatility
If manual configuration is used for each network slice deployment, then specific site requirements can be addressed, but the process cannot be automated and becomes difficult to implement multiple deployments
Solution Approach 1:
The patent enables automation by pre-defining the mapping relationship between service configuration parameters and resource deployment parameters during template creation. This preliminary setup allows the system to automatically generate site-specific configurations through parameter substitution, achieving both site-specific adaptation and full automation
Solution Approach 2:
The patent achieves site-specific adaptation through automated parameter substitution. The system changes specific configuration parameters based on the target site requirements while keeping the overall configuration structure unchanged, thus enabling automation without sacrificing adaptability

AI summary
Embodiments of the present invention provide a method, an apparatus, and a system for creating a network slice. The method includes: receiving, by a network slice control function (NSCF) entity, a service deployment command sent by a network slice management function NSMF entity; obtaining, by the NSCF entity, a service-related requirement parameter, a model, a policy, and a plan of a network slice, and registration information of a network function entity based on the service deployment command; generating, by the NSCF entity, a service configuration scheme of the network function entity based on the model and the policy of the network slice and one or more of the service-related requirement parameter, the registration information of the network function entity, and the plan of the network slice; and sending, by the NSCF entity, the service configuration scheme to the network function entity. Therefore, a network slice can be automatically created.
