reading bts parameters

[Tom Mayer]

hello,

I am not quite sure if this is the right place to ask, so sorry in 
advance for spamming ir i'm in the wrong place.

I have build and run osmocom on my C123. I am using it for a university 
project and we try to read parameters from surrounding BTS. The final 
goal will be to separate real bts from imsi catchers.

So my question is, can I use the osmocom library to gather some data 
from surrounding BTS? Are there some example programs? Would anyone know 
a good way to read the SIM data from the connected C123?

Thanks in advance!
Cheers
Tom

Short example scenario: A very obvious catcher fault would be not having 
set the regional code or having set a wrong regional code. So it would 
theoretically be possible to read the regional code from the own SIM 
card and the regional code of the transmitting BTS and compare those.
