Hi Nghia,

I think you can find the information at the end of this document:

gnuradio.org/redmine/attachments/139/OpenBTS_Guide_En_v0.1.pdf
 
If you google "openbts instructions" this doc is the first result.

Dear David,
 
I’m trying to assess if OpenBTS can be configured to allow “any” mobile to camp 
as quickly as possible, including the very 1st time.
 
I’d like also to get the confirmation that the actual IMSI is only sent to 
OpenBTS the very 1st time and that only the TMSI is then used.
Or is the IMSI still being sent (at least once) upon a identity request on 
subsequent camping?
 
Thank you for your kind help
Rgds
Nghia

The behavior of the system in the initial registration in 2.5 or 2.6 will depend 
on several configuration settings, so there is no single example to offer.
 
What, specifically, are you looking for?  I would recommend actually reading the 
code that controls this, in Control/MobilityManagement.cpp.  And have a copy of 
GSM 04.08 handy for reference.

I have looked at most of this and start to have a fairly good idea of OpenBTS.
But for the project I’m looking at I would need to validate some of the 
assumptions by looking at the real log of the very first registration of a new 
mobile onto OpenBTS.
I think I read in various posts that all mobiles should be able to camp onto 
OpenBTS, but I’d like again to see a typical log of the 1st camping of a new 
mobile.
Another thing I would like also to see is the typical time it takes to camp for 
a new mobile onto OpenBTS.
I guess this depends on the mobile’s software and on the sequence in which the 
freq are searched (beyond the BA list).
I also wonder if there is any way for a MNO to prevent its mobile from camping 
onto a specific network (eg OpenBTS)?
