AMF Module Segmentation for Wireless Roaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in supporting varying requirements of multiple wireless service providers due to different communication parameters and configurations, making it difficult to implement unified Access and Mobility Management Function (AMF) modules for roaming services.
Innovation Solution
The use of dedicated AMF modules for each wireless service provider based on a slice-id assigned to user equipment (UE), allowing communications to be routed to corresponding radio access networks, and converging to the correct AMF module based on the subscriber service profile to efficiently support multiple wireless service providers with varying requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified AMF module is used to support multiple wireless service providers, then device complexity is reduced, but adaptability to different service provider requirements deteriorates
Solution Approach 1:
The patent divides the AMF module into multiple independent instances, each dedicated to a specific wireless service provider. Each AMF module is configured with provider-specific parameters and settings, allowing the system to handle diverse requirements without requiring a single complex unified module. This segmentation enables each AMF instance to be optimized for its specific provider while maintaining overall system manageability.
2Adaptability or versatility
If dedicated AMF modules are used for each wireless service provider, then adaptability to different requirements is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal architecture where multiple AMF modules operate under a common framework and management system. While each AMF module is dedicated to a specific provider, they all follow standardized interfaces and protocols, allowing the system to manage multiple providers without proportionally increasing overall complexity. The universal framework enables efficient resource allocation and coordination across all AMF instances.
3Ease of operation
If a unified AMF module supports multiple service providers with different configurations, then ease of operation is improved, but processing resources and software development costs increase
Solution Approach 1:
By segmenting the AMF functionality into separate provider-specific modules, the system eliminates the need for a single unified module that would require complex configuration management and extensive software development to handle all provider variations. Each segmented module can be independently developed, configured, and optimized, reducing overall processing overhead and software development complexity while maintaining ease of operation through standardized management interfaces.
