#20 ~ 5G Core Network Functions : Learn AMF, SMF, NRF, PCF and More- 5G Architecture | Course 02

Dive into the essentials of 5G Core Network Functions! This video provides a comprehensive look at the key functions that form the foundation of 5G networks. We’ll cover how these functions work together, the differences between reference point and service-based representations, and explore each function in detail—from Authentication and Mobility Function (AMF) to Policy Control Function (PCF). Whether you’re new to 5G or looking to deepen your understanding, this video is designed to make complex concepts easy to grasp.


Topics Covered:
Introduction to 5G Core Network
Understand the fundamentals of 5G architecture and the roles of core network functions.
Two Representation Styles
Explore reference point vs. service-based representation, with insights on why service-based architecture is integral for 5G.


Core Network Functions in Detail
NRF (Network Repository Function): Central registry for network functions, enabling dynamic discovery of services.
AMF (Authentication and Mobility Function): Manages UE authentication, signaling, and seamless mobility across cells.
SMF (Session Management Function): Oversees user sessions, IP allocation, and charging functions.
AUSF (Authentication Server Function): Handles authentication within the subscriber's home network.
PCF (Policy Control Function): Manages policy enforcement for session management, access, and mobility.
UDR & UDM (User Data Repository and Management): Manages subscription data, generating credentials, and registration management.


5G’s Innovation through Service-Based Architecture
Learn how service-based interactions open up flexibility and scalability, empowering 5G to handle diverse and demanding use cases.

Whether you’re studying telecommunications or just curious about how 5G technology works, this video breaks down each core function and explains why these components are essential to 5G’s capabilities.
