AMF Group Association with Network Slice Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network architectures face challenges in selecting an appropriate access management function group that meets service requirements, as existing solutions lack a method to effectively associate access management function groups with network slice information, leading to potential mismatches.
Innovation Solution
An information configuration method and management unit are introduced to determine and configure an association relationship between access management function groups and network slice information, enabling the selection of a suitable access management function group based on service requirements by instructing network units such as NSSF, default AMF, or NRF.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional technical solutions are used for AMF group selection, then the network can operate with existing structures, but the selected AMF group may not meet service requirements or selection methods are not provided
Solution Approach 1:
The patent applies preliminary action by pre-configuring association relationships between AMF groups and network slice information in a management unit before runtime operations. This allows NSSF, default AMF, or NRF to directly utilize pre-established associations during AMF group selection, ensuring service requirements are met without complex real-time analysis, thus resolving the contradiction between reliability and complexity.
Solution Approach 2:
The patent introduces a management unit as an intermediary that maintains and manages the association relationships between AMF groups and network slice information. This intermediary component enables other network elements (NSSF, default AMF, NRF) to obtain accurate selection information without requiring them to implement complex selection logic themselves, thereby improving reliability while keeping the overall system complexity manageable.
2Adaptability or versatility
If network virtualization and service orchestration are implemented to meet dynamic market requirements, then service agility improves, but the complexity of configuring and managing multiple AMF groups and network slices increases
Solution Approach 1:
The patent applies universality by designing a management unit that serves multiple functions: it configures, stores, and provides association relationships between AMF groups and network slice information to multiple different network elements (NSSF, default AMF, NRF). This multi-functional approach enables service agility across different network scenarios while centralizing configuration management to reduce overall complexity.
Solution Approach 2:
The patent utilizes parameter changes by dynamically configuring association relationships between AMF groups and network slice information based on service requirements. The management unit can adjust these associations to adapt to changing market demands and service needs, enabling service agility while maintaining manageable configuration through structured parameter management.

AI summary
This application relates to the field of communications, and provides an information configuration method to configure an association relationship between an AMF group and network slice information for an NSSF, a default AMF, or an NRF, so that the NSSF, the default AMF, or the NRF can select an AMF group meeting a service requirement. The method includes: determining, by a first management unit, an association relationship between information about an AMF group and network slice information, where the association relationship is used to instruct to select the network slice information based on the information about the AMF group or select the information about the AMF group based on the network slice information; and sending, by the first management unit, the association relationship to a first network unit or a management unit of a first network unit; or storing, by the first management unit, the association relationship.
