Pix, that´s what I was trying to say.
The handshaking in that cases is this:
sdcch:ciphering mode cmd/cmp
sdcch:call proceeding (dl)
sdcch:assignment cmd (dl)
tch:assignment complete (ul)
tch:disconnect (dl) -this is the Network Release I mentioned –
It’s almost the same you mentioned, but there’s no Alerting msg.
In that cases, there’s only 20seg between the Ch. Request and Disconnect.
