If a UE is on a data call (CELL-DCH state) and there is in no activity for awhile what would you expect to see occur?

UE should go from CELL-DCH to CELL-FACH then if still no activity to either CELL-PCH or URA-PCH (via CELL-FACH). If they talk about inactivity timers and mention that the state goes from CELL-DCH straight to CELL-PCH or URA-PCH, that is also possible. Bonus they say they would see RADIO BEARER RECONFIGURATION messages when the states are changing.
