Assuming the responsible for mobility management, the AMF is in charge for managing handovers between gNodeB’s (gNB’s), within the Next Generation Radio Access Network (NG-RAN). Formally referred to as an X2 handover, in 5G it is termed an Xn handover.

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.

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.
Read moreWhat is NSSF in 5G?
The NSSF (Network Slicing Selection Function) system is a solution to select the optimal network slice available for the service requested by the user in the 5G environment where various services are provided .
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 .
Read moreWhat is NRF in 3GPP?
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.
