ciph,
thanks for the info. I’ll let the nsn experts reply, but i just want to understand something:
in your trace, the drop occurs during the ciphering phase ? Which means between those two events (if i remember correctly…???) :
– the MSC sends the ciphering mode command (in DL)
– the MS replies in UL with the ciphering mode response
could you share here the content of those two messages when there is the drop?
I would guess the “response” is not sent, because the drop would occur just before…?
Cheers
