Intelligence Network (IN)

I know I would be writing on a very extensive and one of the most important parts of the telephone network. I cannot write about the technical stuff related to IN as this blog is all about the non technical part of the technical things:) And so I am just going to describe what actually IN is, why there was a need to bring in a centralized system:)

So, lets go ahead...

The Intelligent Network (IN), is the standard network architecture whose most important aim is to improve and centralize all the services managed by a telephone operator. 

Initially the primary aim of IN was to improve the core telephony services offered by traditional telecommunications networks, which was majorly making and receiving voice calls. But this was the aim of the “Classic” standard IN services, representing the 1st generation of IN services, which offered limited opportunities for the differentiation between operators.

And therefore the next generation of IN services allowed the operators to introduce and manage other value added services and the traditional ones together with a higher sophistication. IN changed the marketing approaches of the operators completely and thus, helped in the introduction of many VAS services like Mobile Number Portability, financial calling, other utility VAS services which provide limited opportunities for rev generation but which has potential of 100% penetration!
It can be said that IN is the gift at the end of network operators' efforts to modernize their core networks by introducing fully digital components… In general, the IN can be considered as an additional layer on top of any traditional network, such as Public Switched Telephone Network (PSTN), Integrated Services Digital Network (ISDN), or Broadband- ISDN (B-ISDN).
IN provides a service-oriented network architecture, which separates service control functions from service switching functions.
Now, in simple words, it can be said that intelligence is taken out of the switch and placed in a system nodes that are distributed all over the network. It definitely helps the operators to manage the services more efficiently. Also, IN added a scope of introduction of many other services.
IN is supported by the Signaling System #7 (SS7) protocol between telephone network switching centers and other network nodes owned by network operators.

Why IN?
The traditional network architecture was perfect and used to operate in a distributed fashion, by signaling to each other across the network, rather than being controlled by a central processor running the equivalent of a computing application program. It worked perfectly well and no doubt, formed a very vigorous framework when all the network did was set up circuits, time the calls and release the circuits when one of the terminals went on hook.

But as service providers began to develop more complex applications and as the market started growing competitive, the need for new services started developing! And soon, it became clear that only a completely intelligent network would offer a whole range of required advantages.
IN architecture brings all of the switching and transmission functions under the control of a distributed computer system so that a high level of sophistication can be built into services right across the network, instead of being applied only to specific parts.

IN made the monitoring of whole networking system centralized from placing a call to a mobile, logging of the requested number, checking and authenticating the call, allocating a frequency to signaling the receiver’s handset and thanks to IN.

In fact to monitor the movement of the mobile phone and assigning new frequencies or timeslots as its user leaves one cell and enters another is also the responsibility of IN nowJ

Hope the above makes the understanding of IN pretty clearJ. Plz feel free to comment in case you thing something can be added/ changed:)

    1. There are a number of U.FL compatible connectors such as IPEX connectors which are cheaper, but essentially have the same function as U.FL. An example of such a connector can be found below:lated connectors and this is how you can differentiate between the two. For U.FL adapter cables, you can find them at EAD and on theConnex webshop.For More visit.....

  5. Thanks to our readers who commented kindly, all you need to do is to actually push it and it simply and effortlessly pops out! You can then pull it out completely without the need for fishing with fingernails or whatnot. This will prevent the SIM tray flying across the room as seen in my unboxing (using the key wrong as a lever).For More visit.....
