Detailed explanation of the GSM protocol

Heavily techie, but a good overview of the GSM standard including layout of cells, how calls are brought up, etc. etc. Probably helps if you already have some clue as to what the HLR, MS, BSC, etc. are :-)

It is very cool subject? but if you please i want to make a program to know the number of the Cell or the location of cell so how of GIS?

I think it might be possible to get the Cell IDs through the AT command set (see http://www.3gpp.org/ftp/Specs/html-info/27007.htm for details), AT+CREG is, I think, the one you want, but I've never tried it myself.

Or, if you've got a Series 60 phone (Nokie 7650, 3650, etc.) then you could try PsiLoc http://www.psiloc.com/?id=down&kr=2&dz=1&pr=44 as that will record Cell IDs (and presumably it also means there's a way to find out such information on the Symbian OS - I'd guess it would be in the ETel APIs).
