Wireless Terminal Registration Timer for Network Slice Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of 5G network slice-specific authentication and authorization, there is a lack of means for user equipment (UE) to detect abnormal network states during the authentication and authorization process, leading to potential indefinite waiting and failure in providing services.
Innovation Solution
A wireless terminal and core network node implementation that includes a communication unit for sending a registration permission message with information indicating pending authentication and authorization, and a control unit that activates a timer to determine abnormal procedure states, enabling the UE to recognize network abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network performs network slice-specific authentication and authorization procedures, then service security and reliability are improved, but the procedure time and complexity increase
Solution Approach 1:
The network performs authentication and authorization procedures in advance before service activation. The AMF initiates network slice-specific authentication and authorization procedures during the registration phase, so that when services are requested, the UE already has validated access permissions, eliminating the need for repeated authentication during service operations.
Solution Approach 2:
The system implements feedback mechanisms where the network provides status information about pending authentication and authorization procedures to the UE. When the network cannot complete procedures immediately, it informs the UE of the pending state, allowing the UE to adjust its behavior accordingly rather than waiting indefinitely or repeatedly attempting connection.
2Reliability
If the network initiates network slice-specific authentication and authorization procedures, then service security is improved, but the risk of network abnormality and indefinite waiting increases
Solution Approach 1:
The network provides feedback to the UE about the status of authentication and authorization procedures, including when procedures are pending or cannot be completed. This feedback mechanism allows the UE to detect network abnormalities by receiving status information rather than remaining in an uncertain waiting state, enabling proper error handling and service alternative selection.
Solution Approach 2:
The network attempts to complete authentication and authorization procedures during the initial registration phase before service operations begin. By performing these security procedures in advance and informing the UE of their status, the system prevents indefinite waiting during actual service operations and allows for early detection of authentication failures or network abnormalities.
3Manufacturing precision
If the UE waits for network slice-specific authentication and authorization completion, then service accuracy is improved, but the waiting time and system responsiveness worsen
Solution Approach 1:
The network performs authentication and authorization procedures during the registration phase before service operations commence. This preliminary action ensures that when services are actually requested, the UE already has validated access permissions, eliminating the need for waiting during service operations while maintaining service accuracy through pre-validated authentication.
Solution Approach 2:
The network provides feedback to the UE about the completion status of authentication and authorization procedures. When procedures are already completed or cannot be completed, the network informs the UE, allowing the UE to proceed with services immediately rather than waiting, thus reducing waiting time while maintaining service accuracy through proper authentication state management.

AI summary
It is intended to solve or at least reduce such a problem that a UE cannot know that a network is abnormal. A wireless terminal in an aspect of the present disclosure includes: a communication unit (11) configured to receive a registration permission message including at least one piece of information indicating that the procedure of first network slice-specific authentication and authorization is pending; and a control unit (12) configured to activate, upon the reception of the registration permission message, a timer for determining that the procedure of network slice-specific authentication and authorization is abnormal.
