And the AUSF that is responsible to authenticate the UEs along with the AMF and the UDM. It provides a unified repository for user profiles, authentication data, and subscription information.Schematically, the 5G system uses the same elements as the previous generations: a User Equipment (UE), itself composed of a Mobile Station and a USIM, the Radio Access Network (NG-RAN) and the Core Network (5GC), as shown in the figure below.AUSF PCF NG11 UDM N13 N12 N8 N10 AMF N15 Access & Mobility management Function (AMF) MME User Plane Function (UPF) SGW UP PGW Policy Control Function (PCF) PCRF Session Management Function (SMF) SGW CP PGW Authentication Server Function (AUSF) and User Data Management (UDM) HSS/ AAA .In summary, UDM and UDR are integral components of the 5G core network, each with distinct roles in managing user-related data.
It stores the Authentication Management .Unified Data Management ( UDM) is a centralised way to control network user data. In the 5G network, the functions of the HSS are broken up in the authentication server function (AUSF) and the UDM. It is similar to HSS in 4G. It works closely with the AUSF (Authentication Server Function) to authenticate users and provide them with the necessary authorization to access specific services or functionalities.
