7.2  Network Function Services  p. 591

7.2.1  General  p. 591

In the context of this specification, an NF service is offering a capability to authorised consumers.
Network Functions may offer different capabilities and thus, different NF services to distinct consumers. Each of the NF services offered by a Network Function shall be self-contained, reusable and use management schemes independently of other NF services offered by the same Network Function (e.g. for scaling, healing, etc).
The discovery of the NF instance and NF service instance is specified in clause 6.3.1.
Reproduction of 3GPP TS 23.501, Fig. 7.2.1-1: Network Function and NF Service

Up
Each NF service shall be accessible by means of an interface. An interface may consist of one or several operations.

System procedures, as specified in TS 23.502 can be built by invocation of a number of NF services. The following Figure shows an illustrative example on how a procedure can be built; it is not expected that system procedures depict the details of the NF Services within each Network Function.
