NSWO Authentication Using EAP-AKA' for 5G Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of implementing authentication for Non-Seamless Wireless Local Area Network Offload (NSWO) service in a 5G communication system network is exacerbated by the presence of different devices and authentication algorithms compared to 4G networks, leading to potential authentication failures.
Innovation Solution
A method utilizing the Extensible Authentication Protocol-Authentication and Key Agreement (EAP-AKA') authentication algorithm is employed to facilitate authentication for NSWO services in 5G networks, involving the exchange of a Subscription Concealed Identifier (SUCI) and NSWO indication information to ensure compatibility and reduce authentication failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the 5G AKA authentication method is selected for NSWO service in 5G network, then authentication can be performed, but authentication failures occur due to algorithm incompatibility
Solution Approach 1:
The patent changes the authentication algorithm parameter from 5G AKA to EAP-AKA', which resolves the compatibility issue between 5G network and NSWO service requirements, thereby improving authentication success rate while maintaining adaptability
Solution Approach 2:
The patent introduces EAP-AKA' as an intermediary authentication mechanism that bridges the gap between 5G network capabilities and NSWO service requirements, enabling successful authentication without direct conflict between the two systems
2Productivity
If different authentication algorithms are used in 5G network compared to 4G, then network evolution is achieved, but implementation complexity increases
Solution Approach 1:
The patent makes the authentication system multi-functional by supporting both 5G AKA and EAP-AKA' algorithms, allowing the same authentication framework to handle different network scenarios without increasing implementation complexity
Solution Approach 2:
The patent introduces dynamic algorithm selection capability, where the authentication method can be adjusted based on network requirements and service type, enabling flexible adaptation to different scenarios without rigid complexity

AI summary
Embodiments of this application are applicable to the field of communication technologies, and provide a method for authentication for an NSWO service, a device, and a storage medium, applicable to a 5G network. The method for authentication for an NSWO service includes: After determining to perform the NSWO service, the UE sends a SUCI to an AN device. The AN device sends a second request message to an NSWO network element. After determining to perform authentication for the NSWO service, the NSWO network element sends a first authentication request message to an AUSF. After determining to perform authentication for the NSWO service, the AUSF sends a second authentication request message to a UDM. The UDM determines to use an EAP-AKA′ authentication method. Then, the UDM, the AUSF, the NSWO network element, the AN device, and the UE sequentially complete an authentication procedure based on EAP-AKA′ authentication.
