Slice Instance Management Node for Network Slices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slice management systems face complexity and increased load due to the need for complex control logic to determine appropriate service requests from operators and clients, leading to management complexity and increased load on slice management nodes.
Innovation Solution
A slice instance management method where the slice instance management node is introduced to manage slice instances, with operator and client management rights configured during instantiation, allowing direct management operations without additional complex control logic, and automatic deployment based on a description file, reducing management complexity and load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex control logic is set in the slice management node to determine whether service requests are appropriate, then logical isolation between slice instances is ensured, but implementation complexity and load of the slice management node increase
Solution Approach 1:
The patent segments the slice management functionality by introducing a dedicated slice instance management node for each slice instance. This management node is configured with specific management rights for its corresponding slice instance, allowing it to independently handle service requests without requiring complex centralized control logic. The segmentation isolates the control logic into separate, simpler units that only need to evaluate requests against their predefined management rights.
Solution Approach 2:
The slice instance management node acts as an intermediary between the slice instance and other management nodes or clients. It receives service requests, evaluates them against the management rights configured in its description file, and determines whether to allow the operations. This intermediary approach simplifies the overall system by distributing the decision-making logic to specialized nodes rather than requiring complex centralized control.
2Reliability
If complex control logic is set in the slice management node to determine whether service requests are appropriate, then logical isolation between slice instances is ensured, but load of the slice management node increases
Solution Approach 1:
By segmenting the management functionality into dedicated slice instance management nodes, each node only needs to evaluate service requests against its own specific management rights rather than processing all possible requests across all slices. This segmentation reduces the computational load on each individual management node while maintaining isolation between slice instances.
Solution Approach 2:
The management rights are configured in advance in the description file during the slice instance creation process. This preliminary configuration allows the slice instance management node to quickly evaluate service requests by comparing them against pre-defined rights rather than performing complex real-time analysis, thereby reducing the processing load during operation.
3Device complexity
If management rights are configured during instantiation in the description file, then direct management operations can be performed without complex control logic, but the instantiation process becomes more complex
Solution Approach 1:
The management rights are configured in advance during the slice instance instantiation process, specifically included in the description file before the slice instance becomes operational. This preliminary configuration consolidates the complexity into the instantiation phase, allowing the operational phase to use simple, direct management operations based on pre-defined rights without requiring complex control logic.

AI summary
Embodiments of the present application provide a slice instance management method and apparatus. The method includes: receiving, by a slice instance management node, a first service request from an operator system, where the first service request includes information about a management operation to be performed by the operator system on a first network element, and the first network element is a network element in a slice instance managed by the slice instance management node; and if the first service request is within first management rights, sending the information about the management operation to be performed by the operator system on the first network element to the first network element, where the first management rights are management rights of the operator system for the slice instance that are included in a description file of the instance management node.
