known as Reference points according to 3GPP TS 23.501. N3 is the Reference Point between the 5G Access Network and the User Plane Function (UPF) N1 is the Reference Point between UE and the Access and Mobility Management Function (AMF) . It is usually shown as a direct logical connection between the UE and AMF.

NF Repository Function. The NF (Network Function) Repository Function is related to the 3GPP 5G Architecture. This supports the service discovery function . As such, it is able to receive NF Discovery Request from a NF instance and can provide information about discovered NF instances.
Read moreWhat are the requirements guiding the 5G architecture?
5G features include automation and network slicing. Discrete core functions include routing, quality of service, deep packet inspection and a range of security functions, among others. Core architecture provides for the separation of the control plane, the data plane and the subscription management functions .

SGi:- It is the reference point between the PDN GW and the packet data network . Packet data network may be an operator external public or private packet data network or an intra operator packet data network, e.g. for provision of IMS services. This reference point corresponds to Gi for 3GPP accesses.
