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!

Simple Structure of Telecom

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”.

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 userThink after some time some other new users come in network

Why we need Packet Switching

Where it is used

What are the Advantage

How does it work

How we can get rid off from 1 – 1 Network wiring

Each packet have a Unique Address Called “IP” address

Collecting Packets and joining the data by using IP Address

Finally Equipment get data what the first Equipment sent

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

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

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.

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.

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.

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
