The 5G architecture is defined as service-based and the interaction between network functions is represented in two ways.
A service-based representation, where network functions (e.g. SMF) within the Control Plane enables other authorized network functions to access their services. This representation also includes point-to-point reference points where necessary.
A reference point representation, shows the interaction exist between the NF services in the network functions described by point-to-point reference point (e.g. N11) between any two network functions (e.g. AMF and SMF).
Network functions within the 5GC Control Plane shall only use service-based interfaces for their interactions.
Notes :
The interactions between NF services within one NF are not specified in this Release of the specification.
UPF does not provide any services in this Release of the specification, but can consume services provided by 5GC Control Plane NFs.
