There is a Paging Channel in GSM, when you call a mobile there is a String content sent to the called Party via the Paging Channel from the Service Provider.
The String contents are usually sent and controlled by the Sevice Providers.
1. We want to know what are the contents of that string of different Service Providers.
2. We want to modify the String to add our custom parameters and what will be the possible outcome of the same. Thank you all.

Hmmm. The complete set of GSM standards are available free online at www.3gpp.org Finding the right spec of the 100s there will be a challenge.
Paging can only occur after the handset (or more correctly the SIM) has been authenticated by the network. After this authentication, the radio channel is encrypted, so you will not be able to use the paging channel even if you have a suitable transmitter.
I'd be interested to know what you are trying to do
