UE Primary Re-Authentication Based on Network State Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During network registration, authentication failures occur due to specific scenarios affecting network service quality and user experience, particularly when the UE is in states like primary authentication, mobility registration, or handover procedures, leading to unsuccessful primary authentication processes.
Innovation Solution
A primary authentication method that involves receiving a re-authentication request message, determining the UE's state, and sending a response indication message to adapt network element operations accordingly, ensuring successful authentication by considering the UE's current state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the home network sends a primary re-authentication request to the visited network using the original policy, then the authentication procedure can be triggered, but authentication failure occurs when the UE is in specific scenarios such as primary authentication, mobility registration, or handover procedures
Solution Approach 1:
The patent implements dynamic authentication behavior by introducing a state detection mechanism that identifies whether the UE is in specific scenarios (primary authentication, mobility registration, handover procedures). Based on the detected state, the system dynamically adjusts the authentication response: sending a rejection message with a specific cause value when the UE is in these scenarios, and proceeding with normal authentication otherwise. This dynamic adaptation resolves the contradiction between maintaining authentication reliability and adapting to varying UE states.
Solution Approach 2:
The patent changes the authentication response parameters based on UE state. When the UE is detected to be in specific scenarios, the system modifies the cause value parameter in the authentication response message to indicate rejection with a specific reason. This parameter change allows the system to handle different UE states appropriately, improving authentication success rate by avoiding failures in critical scenarios while maintaining normal authentication flow in other states.
2Productivity
If the network element performs authentication operations based on the original policy without considering UE state, then the authentication process can proceed, but network service quality deteriorates due to authentication failures in specific scenarios
Solution Approach 1:
The patent applies preliminary action by detecting the UE state before executing the authentication operation. The system proactively identifies whether the UE is in specific scenarios (primary authentication, mobility registration, handover procedures) and takes preventive action by sending a rejection message with a specific cause value. This preliminary detection and prevention mechanism avoids authentication failures before they occur, thereby maintaining both authentication efficiency and network service quality.
Solution Approach 2:
The patent implements feedback by continuously monitoring the UE state and using this information to adjust the authentication response. The state detection mechanism provides feedback to the authentication decision logic, enabling the system to adapt its behavior based on real-time UE conditions. This feedback loop ensures that authentication operations are performed only when appropriate, maintaining high productivity while ensuring reliable network service quality.

AI summary
A first network element receives a primary re-authentication request message sent by a second network element, where the primary re-authentication request message carries a UE identifier; the first network element determines the UE and acquires the state of the UE according to the UE identifier; then the first network element determines corresponding response indication information according to the state of the UE and sends a primary re-authentication response message carrying the response indication information to the second network element, and the second network element performs a corresponding operation according to the response indication information. The operation of the second network element can be adapted to the current state of the UE to achieve the purpose of improving the success rate of the primary authentication process of the UE, thus improving network service quality and user experience.
