Hi Pix,
SDCCH Drop trace, only show MAIN phases like Basic Assignment / Ciphering / MM signaling / Relase…
Ciphering Flow:
MSC > BSC : Ciphering Mode Command
BSC > BTS : Enctyption Command
BTS > MS : Ciphering Mode Command
MS > BSC : Ciphering Mode Complete
BSC > MSC : Ciphering Mode Complete
But we cannot see where/which above message fail exactly.
