Hi Domi,
I have attached another trace containing the following:
- Location Update + Authentication of the MS that will send the SMS (packets 1-45)
- Sending and receiving an SMS (text: “a5/1”) with encryption set to A5/1 (packets
46-140)
- works
- Sending an SMS (text: “a5/3”) with encryption set to A5/3 (packets 141-730)
- the MS tries to send several times until it gives up. No Ciphering Mode Complete is
received.
- Switching back to A5/1 and resending the SMS with text "a5/3" (packets
731-827)
- works
I hope that helps.
Thanks,
Jan
