Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07

Awake Mode  Sleep Mode

The Awake Mode and the Sleep Mode of the MS can be classified only by the RAS, and

the ACR does not classified the two kinds of status, and recognizes and manages both of

them as the Awake Mode.

Figure 4.5 Awake Mode  Sleep Mode Status Change Procedure

Classification Description

(1)~(2) If the MS does not transmit/receive the data for a certain time (set by the

MS/RAS as the parameter), timeout is generated in its own timer, thus the mode

is changed from the Awake Mode to the Sleep Mode. Then, the MS transmits the

MOB_SLP-REQ message to the RAS, and the RAS transmits the MOB_SLP-

RSP message for this, and the status of MS is changed into the Sleep Mode.

(3)~(4) If the terminating traffic exists in the Sleep Mode MS, the RAS transmits the

MOB_TRF-IND message in the listening period of the corresponding MS, and

the MS which receives this, sets the BW value as 0 in the UL BW Request and

transmits it to the RAS. The RAS receives this message and recognizes that the

status of MS has been changed into the Awake Mode, and transmits the traffic to

the MS.
