Hi,
I have captured a trace. Can you find something out?
Thanks,
Kristian

Hello,
Hi!
two UEs (A and B) are successfully registered in a network. Now A tries to call B. B is paged by the core via A interface but the sysmoBSC/BTS does not seem to page the UE (or UE does not answer paging). What could be the reason for this behaviour? How could the problem be debugged? Please find the attached pcap for your reference.
nice MNC! The P-TMSI doesn't really look that random but it might be an index into an internal data structure?
So on A this looks right. The LAI is 262-79-1 and this is where you are paging. In general it might be:
- osmo-bsc doesn't translate this to actual paging. E.g. not linking/
handling the location area identifier. You could trace the RSL protocol and see if a paging command is being sent (periodically) to the BTS?
- The MS still has a radio channel open. I notice that clear command is
being sent so this is unlikely to be the case. Also IMSI seems to be match.. maybe the MS still calculates the paging group wrongly? That is far fetched though.
