Hi Yanis,
I'm CCing the OsmoconBB list who could perhaps help setup a MSC-GPS
data collector.

Hi all,
not exactly related to airprobe itself, but I am sure people on this
list could answer my question.
So, after reading Tobias Engels' presentation on 25c3 (
http://events.ccc.de/congress/2008/Fahrplan/attachments/1262_25c3-locating-…
), I found out you can perform an HLR lookup and come up with the
current MSC number that "controls" the connection of the subscriber,
for any subscriber.
Yes, every telco company and VoIP provider with SS7 access in the
world always knows where you are. Scary.
My question is, is this MSC number, visible from the
mobile phone
side? If yes, somebody could actually wardrive, to get the MSC
number-to-location mapping?
Can airprobe, or OpenBTS help?
Creating the {MSC -> location} mapping database would be a very
worthwhile exercise. The data collection would have to happen from
phones. Either we create an application for one of the popular phone
platforms (Symbian, Android, iPhone). Anybody on the list knows if
these phones expose the MSC number to application software?
Alternative, the Osmocon project could probably expose the MSC
information easily. The project is still in early stages and it will
take a few months until a collector software could be running. I
wonder if any of the supported Motorola phones have GPS?
Forgive my ignorance on all-things-gsm, I am just
beginning exploring!
Thanks for bringing up the topic!
Thanks all,
Yanis
