How can I extract the GSM cell ID details (Either name or ref numbers) and the signal strength from a GSM modem. Is there a command to return a value?
Ideally would like to be able to SMS the cell ID on command, to be able to poll the mobile and get the approximate location.
Also, can you extract the details of ALL the nearby GSM towers in range - not just the closest? Then by triangulation you get more accurate positions.
THANK YOU!

Great answer
... I was also wanting the Cell ID text data - which is the broadcast suburb position etc... as well as the timing advance figure to show range... perhaps I should get the specs from the chip manufacturers if this is not 'standard' GSM modem AT protocols.
But thanks for your answer - it is informative... and encouraging to my project! I may contact you again :-)

GSM 07.07 specifies standard AT commands for several of the applications you mention. Where supported, the +CREG command will return the ME network registration status and if possible, a two byte location area code and a two byte cell ID. As for signal quality, the +CSQ command will return both a received signal strength indication (RSSI) and the channel bit error rate.
If you need additional information, feel free to ask.
