5G Core Network, AMF, SMF, UPF & Registration Steps | Chapter 7 Part7X1 | شرح مبسط بالعامية المصرية

In this video, we explain Chapter 7, part7X1 in a simple, clear, and structured way.
This part of the lecture introduces the wireless core network, with strong focus on the 5G Core, its functional components, the difference between control plane and user plane, the role of key functions such as AMF, SMF, UPF, AUSF, UDM, UDR, and UDSF, and finally the full step-by-step process of joining a 5G network.

In this explanation, you will understand:

the meaning of the wireless core network
the difference between:
wireless access network
and wireless core network
the big picture of 5G Core Functional Components
why 5G Core is mostly about:
control plane services
the separation between:
control plane
and user plane
the role of:
AMF (Access, Mobility Management Function)
SMF (Session Management Function)
UPF (User Plane Function)
AUSF (Authentication Server Function)
UDM (Unified Data Management)
UDR (Unified Data Repository)
UDSF (Unstructured Data Storage Network Function)
how UPF acts as a relay between:
UE
and the Internet
why UPF is responsible for:
policy enforcement
traffic usage measurement
QoS policing
tunneling
the role of AMF in:
connection management
reachability management
mobility management
access authorization
location services
the role of SMF in:
managing each UE session
IP address allocation
selecting the associated UPF
QoS control
control aspects of User Plane routing
the role of AUSF in:
device authentication
the role of UDM in:
user identity management
generation of authentication credentials
the role of UDR in storing:
static subscriber-related information
the role of UDSF in storing:
unstructured data
similar to a Key/Value Store
the meaning of:
5G interfaces
and CUPS (control/user-plane separation)
important interfaces such as:
N1
N2
N3
N4
N5
N7
N8
N10
N11
N12
N13
how the data plane uses:
tunneling
GTP-U
UDP
IP
the meaning of User plane tunnels in 5G Core
how packets are encapsulated and forwarded between:
UPF
base station
and UE
the concept of Identity in 4G/5G
why in cellular systems you are a:
customer
of a wireless service provider
with a home cellular network
the role of:
SIM
or vSIM
how SIM contains:
identity information
and cryptographic key info
the difference between:
cellular identity
and Internet identity approaches
how Internet identity is often based on:
name + password
or name + public key certificate
the full steps of:
Joining a 5G network
the two major phases:
registration
session establishment
how the process includes:
RRC connection setup
Registration request
Identity request/response
authentication, security
registration accept
PDU session establishment request
session creation
device subscription retrieval
UPF session establishment
device IP address and tunnel setup
RAN data plane configuration
and finally the 1st uplink datagram in data plane

This video is very important for students studying:
Wireless and Mobile Networks, 5G Systems, Mobile Core Networks, Radio Access Networks, Computer Networks, and Telecommunications.

الشرح في الفيديو بيركّز على الربط بين 5G Core architecture, control plane, user plane, network functions, interfaces, identity, وregistration/session establishment, مع الحفاظ على Scientific Terminologies in English علشان الفهم الأكاديمي يكون مضبوط وواضح جدًا ومترابط.
