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.

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.

An introduction to 5G service-based architecture Introduced to improve the modularity of the network system , SBA lets network elements or network functions (NFs) in 5G communicate with each other over a service-based interface. It allows the decoupling of NFs with more precise functionalities.18 Mar 2021

5G Core Network inherits control and user plane separation (CUPS) architecture from 3GPP Release 14 . In 4G EPC, S/PGWs are decomposed to S/PGW-C and S/PGW-U to provide an efficient scaling of services independently.
Read moreWhat is service based architecture in 5G?
The 3GPP defines a Service-Based Architecture (SBA), whereby the control plane functionality and common data repositories of a 5G network are delivered by way of a set of interconnected Network Functions (NFs), each with authorization to access each other’s services.
