4.1 Introduction p. 8
Within the 5GC, the NSSF offers services to the AMF, SMF, NWDAF and NSSF in a different PLMN via the Nnssf service based interface (see TS 23.501 and TS 23.502).
Figure 4.1-1 provides the reference model (in service based interface representation and in reference point representation), with focus on the NSSF and the scope of the present specification.
The functionalities supported by the NSSF are listed in clause 6.2.14 of TS 23.501.
