Did anyone try a Samsung mobile phone?
I tried 3 different kind of Samsung and none of them can attach to the
network (but they can see it with manual research).
Problems with :
Samsung U600
Samsung PlayerAddict I900
Samsung E840
Working fine with Nokia and Ericsson mobile phones

No. It means the PDA might first try to register with that Dutch TMSI and
then the network will need to explicitly request
the IMSI. It's not
supposed to use that Dutch TMSI in France, but it might try if there's a bug
in its GSM stack.
Well I'm sorry, but I'm still not convinced about that. Cause that would be
a major bug, which won't be accepted by the biggest user group for PDA
phones (like business men, or presidents like Obama).
Ah. Sorry. You are probably correct then. There's something about the
BCCH that the phone doesn't like.
That's I think is most likely the case.
That's part of what I mean by TMSI resolution: if you can't recognize or
support the TMSI, turn around and request the
IMSI.
Yeah, that is what OpenBSC does, I think. But Harald, Holger, Dieter and
others know more about it.
The problem, sometimes, is that some phones don't drop the TMSI. They
insist on using it, even when it should have been
invalidated.
In that case, I would see some negotiations from the debug bsc_hack, which
there is not. So my assumption is still some missing information in the BCCH
channel. Cause once again, trying to register to my BTS manually failed and
I don't see any attempt to do just a simple Radio Resource request. The
latter one I can't confirm that for 100 %, because it's possible the debug
doesn't show all of that.
The only way we could get the Treo 650 to stop sending us AT&T's old TMSI
was to assign it one of our own.
Well, at least the Treo talked to you.
