AMF Registration Management for 5G Non-3GPP Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G communication systems face challenges in effectively managing the registration state for terminals accessing the network via non-3GPP access, due to differences in registration characteristics compared to 3GPP access.
Innovation Solution
A method is proposed for managing the registration state of terminals in the access and mobility management function (AMF) of a 5G network, specifically for non-3GPP access. This involves distinguishing between different access types, maintaining separate management for non-3GPP access, and utilizing messages to request and transmit location information and mobility management data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate management for non-3GPP access is implemented, then registration management effectiveness is improved, but system complexity increases
Solution Approach 1:
The patent divides the access management system into separate handling paths for 3GPP and non-3GPP access types. The AMF (Access and Mobility Management Function) is configured to identify and process non-3GPP access requests through distinct procedures, including separate registration management workflows and location information handling mechanisms. This segmentation allows tailored management for non-3GPP access without affecting 3GPP access operations.
2Reliability
If location information management is enhanced for non-3GPP access, then mobility management is improved, but signaling overhead increases
Solution Approach 1:
The patent implements preliminary action by having the terminal provide location information proactively during the registration procedure for non-3GPP access. Instead of requiring separate location updates later, the terminal includes its location information in the initial registration request message. The AMF stores this location information and uses it for subsequent mobility management operations, reducing the need for additional signaling messages.
