New to telecom domain, need detailed information regarding few terms

Hi,

I am C++ developer and new to telecom domain. I want detailed understanding and their significance about following terms,
1. SRI (send routing information)
2. Forward Short Message
3. ATI (Anytime Interrogation).

One more thing I wish to add , when we send SRI server should return cell info from HLR then why we send Class0 message.

Thanks in advance
