What is AUSF?

AUSF stands for Authentication Server Function. It's a crucial component in 5G networks responsible for authenticating users and devices before granting them access to the network. It works closely with other 5G core network functions like AMF (Access and Mobility Management Function) and UDM (Unified Data Management) to verify user credentials and ensure secure network access. It is a key element in the 3GPP defined 5G security architecture.

What other technologies are related to AUSF?

AUSF Competitor Technologies

HSS

HSS (Home Subscriber Server) is the equivalent function in 4G networks. AUSF is the authentication server in 5G, therefore they perform similar functions in different network generations, making them competitors.

PCRF

PCRF (Policy and Charging Rules Function) is a 4G technology for policy control. PCF is its 5G equivalent. AUSF doesn't directly compete with PCRF, but given the transition to PCF in 5G, PCRF is becoming less relevant, similar to HSS vs AUSF.

AUSF Complementary Technologies

UDM

UDM (Unified Data Management) is a core network function in 5G that manages subscriber data and is essential for the AUSF (Authentication Server Function) to authenticate users. Hence, strongly complementary.

SEPP

SEPP (Security Edge Protection Proxy) is a key security function within the 5G core network that protects the network from external threats. As AUSF requires secure communication, SEPP provides that security, thus it's complementary.

NSSF

NSSF (Network Slice Selection Function) is responsible for selecting the appropriate network slice for a user. While AUSF doesn't directly interact with NSSF for primary authentication, its services might be used in conjunction within a slice. Therefore, considered complementary.
