AUSF (Authentication Server Function) In 5G-NR and its functionalities

AUSF (Authentication Server Function) is an essential component of the 5G network architecture. It is responsible for verifying the identity of a subscriber, validating their subscription data, and determining the appropriate security context for the subscriber.
One of the primary functions of the AUSF is to support 5G authentication and authorization procedures. When a subscriber attempts to connect to the 5G network, the AUSF plays a key role in verifying their identity and ensuring that they have the proper authorization to access the network.
Hi All,
There are lot of new member joined so i am providing the links of ORAN/5G/LTE videos which have in our channel.
