Although I have not been there I am reading this with interest.

Regarding 4.1, when people start playing with their SIMs and trying manual registering into Vodafone, the forbidden network is deleted from the SIM, so this measure only is effective against accidentally catching the wrong network - or is there another field in the SIM that totally blocks access to certain networks?

4.2, I am OpenBTS user, but I also have sometimes strange behavior when LU is missed for some reason, or when the BTS is restarted.

6., early call assignment seems to make problems with some phones, at least with OpenBTS and old Sagem phones this feature makes the phones ring for very short time, then the call attempt ends, and a missed call shows up in the display.

This year I plan to attend...

Ralph.

hi,

Daniel and me started a small report for the 30C3 network but we are kind of stalled. Anyone feels like doing some review and providing feedback?
