Whatt is LOVE..???

LOVE...
Do you think that Love is a magic , or  kind of sensation generated spontaneously when Mr or Ms Right comes in your life??
If this is what you think Love is all about then i think that not may be a long lasting one.....because the way it is generated....it can degenerate also (spontaneously)


My friends I would like to share my view about LOVE
Whatever you'd think about mine views Please comment....


According to me - Love is an attachment which is due to deep appreciation and thinking of someone's good qualities,morals and ethics.
 Nice looks,good personality, intelligence or talent are only the factors of attraction.But the qualities and goodness are the points which lead towards real Love.
When we start to love somebody we start ignoring their bad or weak points, just because we are focusing on their goodness.
Love can happen again and again... 
There's nothing like love happens only once....It's just that because one becomes more preservative after first Love and Closes the doors of his/her heart.
Yes,but sure it takes more time and care to fall in Love again.
In words of Science..."Love can be created or destroyed"
Sometimes creating love takes more effort...and sometimes destroying(forgetting).
...A lot more to describe Love....words can be short for it.

GSM - AN OVERVIEW

GSM is the most important technologies used for mobile telephone networks
The first GSM network was rolled out during the early nineties.Global System for Mobile communication (GSM) is developed in the working groups associated to European Telecommunications Standards Institute (ETSI).
Lets not go deeper into the history and theories and discuss some technical stuff about it.


  • FUNCTIONAL VIEW:
The primary goal of a mobile telephone network that a subscriber
having a mobile telephone can make and receive calls anywhere. To achieve this
goal, some major functions are required.
  1. Call management and call processing - it includes all the processes during call setup and call release
  2. Radio management - issues related to communication path and frequencies
  3. Mobility management - the network should be aware of the location of a user to avoid unnescesary                                                    network load and operations
  4. Charging - related to billing and registration (as billing depends also upon user location)
  5. Security  -  various encryption and authentication techniques.

  • LOGICAL VIEW:
The GSM networks are divided into two logical parts:
  1. Network Switching Sub-system (NSS) - It is responsible for call processing, mobility management, and subscriber related functions such as charging and security
  2. Base Station Subsystem (BSS) - It performs the radio related functions towards the Mobile Stations (MS), e.g. a mobile phone.
