Narendra Singh Negi, a senior recruitment consultant at Net Consulting International, shares insights on telecom networks, specifically circuit switching and packet switching. He explains how data is transmitted efficiently through unique IP addresses, enabling robust communication across networks like GPRS. Additionally, he discusses the roles of key components such as the Radio Network Controller (RNC), Gateway GPRS Support Node (GGSN), and Serving GPRS Support Node (SGSN) in managing mobile communications.

1. Hi,
I am Narendra Singh Negi
working with Net Consulting International
As Senior Recruitment Consultant & Database Specialist
from April 2009 to till now
During this period I have grasped the telecom
knowledge, so today I would like to share my Knowledge
with all of you!

2. Simple Structure of Telecom
Email (1)

3. This is a method of breaking data files into small packets
or chunks in order to send them across a network
When we want to make a call to someone else then a dedicated
connection is set up between us. While that cal is taking place between
us have sole use of the telephone line no one else can use it. Once the
call is finished the connection is broken and the line becomes available
for somebody else to use. The line is tied up for the whole length of the
call . This is called “Circuit Switch”.

4. Here you can see that to communicate 1st user
to 2nd user we need Specifically network wire,
and same we have to do with 3rd to 4th user
Think after some time some other new users
come in network

9. Why we need Packet Switching
How does it work
Where it is used
What are the Advantage
How we can get rid off from 1 – 1 Network wiring

12. This method works extremely well, Because if one branch gets too
busy or broken, then the packet are automatically routed another
path Instead.

13. Information send by 1st user and it is on A, if B path is busy information would go
through the C path or C path is busy than it would go through the B path

14. Packet switching is used to optimize the use of the channel
capacity available digital telecommunication networks
such as computer networked.
It is tightest upper bound on the amount of information
that can be reliably transmitted over a channel.
To minimize the transmission latency (the time it takes for
data to pass across the network).
To increase robustness of Communication.

16. The Radio Network Controller (or RNC) is a governing
element in the UMTS radio access network (UTRAN)
and is responsible for control the Node Bs that are
connected to it. The RNC carries out radio resource
management, some of the mobility management
functions and is the point where encryption is done
before user data is sent to and from the mobile. The
RNC connects to the Circuit Switched Core Network
through Media Gateway (MGW) and to the SGSN
(Serving GPRS Support Node) in the Packet Switched
Core Network.

17. The Gateway GPRS Support Node (GGSN) is a main component of
the GPRS network. The GGSN is responsible for the interworking
between the GPRS network and external packet switched
networks, like the Internet .
The GGSN converts the GPRS packets coming from the SGSN into
the appropriate packet data protocol (PDP) format (e.g., IP) and
sends them out on the corresponding packet data network. In the
other direction, PDP addresses of incoming data packets are
converted to the GSM address of the destination user.
The readdressed packets are sent to the responsible SGSN. For
this purpose, the GGSN stores the current SGSN address of the
user and his or her profile in its location register. The GGSN is
responsible for IP address assignment and is the default router for
the connected user equipment (UE). The GGSN also performs
authentication and charging functions.

18. The Serving GPRS Support Node (SGSN) is a main
component of the GPRS Network, which heddles all
packet switched data within the network, ex the mobility
management and authentication of the users.
The SGSN perform the same function as the MSC. MSC
The Mobile Switching Centre (MSC) is a telephone
exchange that makes the connection between mobile users
within the network, form Mobile users the public switched
Telephone network
