4.1 Introduction

Within the 5GC, the NEF (UAS-NF) offers services to the AMF, SMF, and PCF via the Nnef service based interface, and the NEF (UAS-NF) offers services to the SMF+PGW-C via the Nnef service based interface for UUAA-SM and C2 procedure supported in EPS (see 3GPP TS 23.256 [6]).

Figure 4.1-1 provides the reference model (in service based interface representation and in reference point representation), with focus on the NEF (UAS-NF) and the scope of the present specification.
