CMAC_KEY_COUNT value updated by the MS.
(9) The RAS notifies the ACR of the data path setup result using the Path Registration
Ack message.
(10) When receiving the RNG-RSP message, the MS sends the BW Request Header to
notify the system that it has transited to Awake mode.
(11)~(12) Now the MS has transited to Awake mode and a new Transport CID has been
assigned. When the Diameter/RADIUS protocols are used, they are operated
according to the Idle Mode Notification on/off. If it is on, the accounting information is
updated using the Diameter ACR/RADIUS Accounting Request message.
Idle Mode Æ Awake Mode Transition
For the procedure used when the MS transits from Idle Mode to Awake Mode
because of a paging, refer to ‘Paging’.
