Hello!

Thanks a lot for very interesting material!

The next portion of collected facts:

1) in our country there are three operators: one use ericsson equipment, other – ericsson + huawei and we use ALU. In all networks Nokia 6230 behaves itself in the same way – shows open lock at the beginning of call

2) here are messages from TEMS:

MS1
Ciphering Mode Command

Time: 13:39:16.39
Frame number: 670251

Skip indicator : 0
Protocol discriminator : (6) Radio resources management messages
Message type : 53
Cipher Response
CR : (1) IMEISV shall be included
Cipher Mode Setting
Algorithm ID : Cipher with algorithm A5/1
SC : (1) Start ciphering

MS1
Ciphering Mode Complete

Time: 13:39:16.42
Frame number: 670251

Skip indicator : 0
Protocol discriminator : (6) Radio resources management messages
Message type : 50
Mobile identity
Odd/even indication : (0) Even number of digits
Type of identity : (3) IMEISV
Identity digits (BCD) : 3574450069750300

As far as i understand it mean that ciphering had been established successfully.

What do you think?

Thank you very much for help!

BR, Peter!
