full_form: Authentication Server Function
context: NG-RAN. - Trace Collection Entity IP Address for the file-based trace reporting or Trace Reporting Consumer URI for the streaming trace reporting. 2. UDM stores the trace control and configuration parameters received from the management system. 3. UE connects to the Untrusted non-3GPP Access Network and obtains an IP address 4. UE performs IKE authentication with N3IWF 5. N3IWF selects appropriate AMF 6. N3IWF sends N2 Registration request to AMF 7. AMF requests AAA Key from AUSF 8. UE authenticates with AUSF via N3IWF and AMF 9. UE establishes Signaling IPsec SA with N3IWF 10. UE sends SMC Complete to AMF 11. AMF receives the trace control and configuration parameters information from UDM via Nudm_SDM_Get operation (see step 14 in clause 4.2.2.2.2 and clause 5.2.3.3 of 3GPP TS 23.502 [41]). 12. AMF stores the trace control and configuration parameters received from the UDM. 13. AMF starts the Trace Session according to the received configuration. 14. AMF establishes Policy
description: The Authentication Server Function (AUSF) is a network function responsible for authenticating users and providing authentication services to other network functions, such as the Access and Mobility Management Function (AMF). It plays a critical role in securing access to the network and ensuring that only authorized users can connect.
explanation: The text describes AUSF's responsibilities in user authentication and its interaction with other network functions like AMF. This clearly classifies it as a Network Function.
