Network Slice Template Management Automating Service Instance Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network instance deployment process is complex and inefficient, requiring significant manual intervention due to the need for manual specification of resource requirements and service parameter configuration, which hinders the ability to adapt to changing user demands and deploy network slices effectively.
Innovation Solution
A network slice template management method that involves a first management unit receiving a subnet management request, obtaining network service descriptor association information, and creating a network service instance based on this information, thereby automating the deployment process and reducing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual specification of resource requirements and service parameter configuration is used, then deployment control and accuracy are improved, but deployment complexity and time consumption increase significantly
Solution Approach 1:
The patent pre-configures resource requirements and service parameters in network slice templates before deployment. During actual deployment, the network slice management function directly retrieves these pre-configured parameters from the template, eliminating the need for manual specification at deployment time. This preliminary action maintains deployment accuracy while significantly reducing deployment time and complexity.
Solution Approach 2:
The network slice management function automatically obtains resource requirement information and service parameters by querying the network slice template itself, without requiring manual intervention. The system serves itself by extracting necessary configuration data from the template, reducing both deployment time and operational complexity while maintaining accurate parameter configuration.
2Extent of automation
If manual intervention is used in network instance deployment, then deployment control is improved, but automation level and efficiency deteriorate
Solution Approach 1:
The patent extracts resource requirement information and service parameters from the network slice template, separating the configuration data retrieval process from manual deployment operations. The network slice management function automatically extracts and applies these parameters, increasing automation while simplifying the overall deployment process by eliminating manual configuration steps.
Solution Approach 2:
The network slice template acts as an intermediary that contains all necessary resource requirement information and service parameters. The network slice management function queries this template to obtain configuration data, automating the deployment process while reducing complexity by using the template as a centralized configuration repository rather than requiring manual specification of each parameter.
3Adaptability or versatility
If network slices are abstracted using logic instead of physical resources, then adaptability to changing user requirements is improved, but system complexity increases
Solution Approach 1:
The patent creates virtual copies of network resources through network slice templates that represent logical abstractions of physical infrastructure. These templates can be instantiated multiple times to serve different user requirements without modifying the underlying physical network, enhancing adaptability while managing complexity through standardized virtualization models.
Solution Approach 2:
The network slice template serves multiple functions: it defines resource requirements, specifies service parameters, and enables deployment of multiple network slice instances. This multi-functionality allows the system to adapt to diverse user requirements using a single standardized template structure, improving versatility without proportionally increasing system complexity.

AI summary
A network slice template management method includes: receiving, by a first management unit, a subnet management request, where the subnet management request carries indication information of a subnet template; obtaining, by the first management unit, network service descriptor association information or a network service descriptor based on the indication information of the subnet template; and obtaining, by the first management unit, a network service instance based on the network service descriptor association information or the network service descriptor.
