Understanding Service-Based Architecture (SBA) in 5G-NR

HI All,
Please go through
5G Network Functions:
User Equipment (UE)Radio Access Network
(UPF) User plane Function
(DN) Data network
(AUSF) Authentication Server Function
(AMF) Core Access and Mobility Management Function
(SMF) Session Management Function
(NSSF) Network Slice Selection Function
(NEF) Network Exposure Function
(NRF) NF Repository Function
(PCF) Policy Control function
(UDM) Unified Data Management
(AF) Application Function
S-GW and P-GW have been divided into session management function (SMF) and user plane function (UPF)
Functions :
(AUSF) :Subscriber authentication, during registration or re-registration with 5G, is managed by the Authentication Server Function.
(AMF) :NAS signaling termination and security, Access Authentication, Support of Network Slicing. Support of intra-system and inter-system mobility, Mobility management control (subscription and policies);
(SMF) : UE IP address allocation and management; Session Management, Selection and control of UP function, Control part of policy enforcement and QoS.
(UPF) :Anchor point for Intra-/Inter-RAT mobility, Packet routing & forwarding, External PDU session point of interconnect to Data Network, DL packet buffering and DL data notification triggering.
