4 Overview p. 8
4.1 Introduction p. 8
Within the 5GC, the NEF offers NIDD services to the NF (e.g. SMF) or the NEF offers MO SMS service to the NF (e.g. SMS-SC) via the Nnef service based southbound interface (see TS 23.501, TS 23.502 and TS 23.540).
Figure 4.1-1 provides the reference model (in service based interface representation and in reference point representation), with focus on the NEF and the scope of the present specification.
The functionalities supported by the NEF are listed in clause 6.2.5 of TS 23.501.
