??5G Overall Architecture??

??5G Overall Architecture?? :

Architecture of a 5G network, focusing on the connectivity between different network components

?? AMF/UPF (Access and Mobility Management Function / User Plane Function):

These are the core network components.

?? AMF is responsible for session management and mobility management.

?? UPF handles data packet routing and forwarding.

?? gNB (Next Generation NodeB):

These represent the base stations in the 5G network.

They are the points of contact for mobile devices to access the network.

?? ng-eNB (Next Generation evolved NodeB):

An evolved form of the traditional 4G base station, enabling connection to the 5G network.

?? Interfaces:

?? N2: Interface between gNB and AMF for control signals.

?? N3: Interface between gNB and UPF for user data.

?? NG: Interface between gNB/ng-eNB to AMF/UPF for both control and user data.

?? Xn: Interface between gNBs/ng-eNBs for handover and session continuity.

?? 5GC (5G Core):

The core network that performs essential functions like authentication, session management, and mobility management.

?? NG-RAN (Next Generation Radio Access Network):

The radio access network part of 5G, consisting of gNBs and ng-eNBs.

???? Examples:

A user on a video call ?? would be connected through a gNB to the AMF/UPF for seamless data transmission.

A moving vehicle ?? using 5G for navigation would rely on Xn interfaces for smooth handover between different gNBs/ng-eNBs.

This architecture allows for high-speed data transmission, low latency, and supports a vast number of connected devices, which is essential for modern applications like streaming, gaming, autonomous vehicles, and the Internet of Things (IoT).
