Parent-Child Slice Management for Multi-Operator Resource Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network systems using virtualization technology primarily manage slices for a single business operator, lacking the capability to efficiently assign slices to multiple business operators.
Innovation Solution
A slice management system comprising child slice management devices managed by one or multiple business operators and a parent slice management device that stores and notifies slice information, allowing for the assignment of slices across multiple operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one business operator manages slices independently, then slice assignment is simple and direct, but the system cannot assign slices to multiple business operators
Solution Approach 1:
The slice management system is segmented into a parent slice management device and multiple child slice management devices. The parent device handles overall coordination and multi-operator assignments, while child devices manage specific slice instances. This segmentation allows the system to support multiple business operators without requiring complete redesign of the entire management architecture.
Solution Approach 2:
The parent slice management device acts as an intermediary between multiple business operators and the slice resources. It receives slice assignment requests from multiple operators, coordinates resource allocation, and distributes appropriate slices to child devices for implementation. This intermediary structure enables multi-operator support while maintaining manageable complexity through centralized coordination.
2Adaptability or versatility
If a parent-child management structure is introduced to support multiple operators, then slice assignment to multiple business operators becomes possible, but the system complexity increases
Solution Approach 1:
Child slice management devices are equipped with autonomous capabilities to manage their assigned slices independently. They can perform local slice instantiation, resource allocation, and operational tasks without requiring constant parent device intervention. This self-service capability simplifies operations by allowing child devices to handle routine tasks autonomously while the parent device focuses on high-level coordination.
Solution Approach 2:
The parent slice management device performs preliminary actions by pre-configuring and distributing slice templates and resource allocations to child devices before actual slice assignment requests are processed. This preliminary preparation reduces the complexity of real-time operations, as child devices receive pre-processed configuration data that simplifies their execution tasks.

AI summary
An object is to provide a slice management system capable of assigning slices to a plurality of business operators. In a parent SMF 100, a slice management table 103 can manage resources of a slice managed by a child SMF 100a or the like, and a communication unit 101 can notify the child SMF 100a or the like of the resources. The child SMF 100a or the like receives the resources and stores the resources in the slice management table 106. Therefore, the child SMF 100a or the like can manage the resources of the slice managed by the child SMF 100a or the like, and the child SMF 100a can independently enable the management of the resources.
