Idle Mode Æ Awake Mode(QCS)

When the MS in Idle mode responds to a paging caused by incoming traffic or when the

MS in Idle mode sends traffic, it transits from Idle mode to Awake mode.

For both cases, the MS has to perform a network re-entry procedure to enter Awake Mode.

The Mobile WiMAX system should consider the QCS procedure as a network re-entry

method by default.

The figure below shows the procedure (QCS) in which Idle mode is changed to Awake

mode during network re-entry.
