Answer : how mapping between different protocols occur?

No protocol mapping would happen. This is for one.

For two:
IN order to implement such thing you would need to accomplish the following stages:

1. Create/download/install and application that is able to check the mail on the Hotmail account.
This application can sit either on Internet site (some server side programming will be required: you will have to "emulate" a mail client program on that site"(
Another way is to put it on your PC.

2. To catch the event of new mail arrival.

3. Generate an SMS text and send it through some SMS center, and by "some" I mean an available one: either on Internet or your own Cell carrier.
Your program should create a text, connect/login to SMS center , send an SMS through it.

thats it.

So as you can see there is no "mapping" between protocols. The only protocols that will be used are: HTTP/HTTPS (web mail check), and SMS.

I believed you can accomplitsh this task without any programming at all - just make some scripts on Linux or for windows there are ready applications for Checking Hotmail, sending SMS messages. May be you'll find an application that has all of the needed functionality.
