David A. Burgess dburgess at jcis.netHolger - [OpenBTS - I'm cross posting this from OpenBSC.] A problem we had with a lot of PDA phones in OpenBTS was that they would attempt to register or access CM services by TMSI, even when our system had a different MCC/MNC/LAC and even when we had not yet assigned a TMSI. I first saw this with a Palm Treo 650 but have seen it with other PDA phones since then. I suspect a lot of them are using the same broken GSM chipset that does not follow the standard's TMSI invalidation rules. I don't know what you do for TMSI resolution in OpenBSC, but if you don't handle this case correctly you will have problems with these handsets. -- David On Jun 24, 2009, at 7:33 AM, Holger Freyther wrote: > > >> But Holger, do you also have registering issues with pda-phones, like >> the HTC or maybe even the iPhone? > > I remember we had some problems with the PDA phones at the 25C3, I > currently > have no physical access to any BTS and can't do tests. > > z.
