4.1.3 Status Change

Awake Mode  Idle Mode

If the data traffic is not transmitted/received for a certain time, the status of MS is changed

from the Awake Mode to the Idle Mode.

Sleep Mode  Idle Mode Change

The MS of the Sleep Mode is not changed into the Idle Mode, immediately.

Before being changed from the Sleep Mode into the Idle Mode, the MS is changed

to the Awake Mode, first, and then, after requesting DREG, it is changed into the

Idle Mode.

The deregistration procedure to be changed into the Idle Mode is divided into the MS-

initiated Idle Mode change and the Network-initiated Idle Mode change, and the following

indicates the procedure of the MS-initiated Idle Mode change.
