Hi everyone,
First of all congratulations for the community's work, i've seen Talks about
gsm/osmocom/Core network (Karsten, Harald, Sylvain, Tobias). It's impressive.
I'm pretty new in the GSM world.
I would like to practice tests concerning the obtention of LAC,CID (1/ of the phone using
osmocombb, 2/on regular phone in same area of the osmo-bb phone 3/on a phone somewhere)
According to the talks this can be achieved using MAP/SCCP and core network access, but i
dont really want to mess with this.
Can O-bb helps me to retrieve this LAC,CID informations in these three situations? (for
the first case, i'm sure it can.)
According to gsm protocol stack (
http://www.rfwireless-world.com/images/gsm-protocol-stack.jpg ) we can see that the BSC is
able to talk with MSC using BSS MAP/SCCP does that mean that i actually need to use
openbsc on a phone
and osmoBB on another phone to achieve my tests?
For all of this, will i find a good starting code in sylvain/burst_ind branch? will i need
non standard baud-rates serial cable? (You guessed it right, i still not have ordered my
serial cables).
What i've done so far is getting E88 device and compiled the core libs and bb.(i
really start)
I know my questions are pretty noob compared to all other messages in this list, please
accept my apologies if i'm posting in the wrong list.
Thank you in advance.
Jean.
