14.7.3î™–î™–î™–î™–Defined values
Parameter Type Description
<mode> Number Indication to disable or enable the use of PSM in the UE. Allowed values:
• 0 (default and factory-programmed value): disable the use of PSM
• 1: enable the use of PSM
• 2: disable the use of PSM and reset all parameters for PSM to factory-programmed
values.
<Requested_
Periodic_RAU>
String Requested extended periodic RAU (T3312) value to be allocated to the GERAN/
UTRAN, one byte in an 8 bit format. For the coding and the value range, see the GPRS
Timer 3 IE in 3GPP TS 24.008 [12]
<Requested_GPRS_
READY_timer>
String Requested GPRS READY timer (T3314) value to be allocated to the UE in GERAN/
UTRAN, one byte in an 8 bit format. For the coding and the value range, see the GPRS
Timer 3 IE in 3GPP TS 24.008 [12]
<Requested_
Periodic_TAU>
String One byte in an 8 bit format. Requested extended periodic TAU value (T3412) to be
allocated to the device in E-UTRAN. The requested extended periodic TAU value is
coded as one byte (octet 3) of the GPRS Timer 3 information element coded as bit
format (e.g. "01000111" equals 70 hours). For the coding and the value range, see the
GPRS Timer 3 IE in 3GPP TS 24.008 Table 10.5.163a/3GPP TS 24.008 [12]. See also
3GPP TS 23.682 [153] and 3GPP TS 23.401 [154].
• SARA-R4 - The factory-programmed value is 150 s. The default value is "01100000".
<Requested_Active_
Time>
String One byte in an 8 bit format. Requested Active Time value (T3324) to be allocated to
the UE. The requested Active Time value is coded as one byte (octet 3) of the GPRS
Timer 2 information element coded as bit format (e.g. "00100100" equals 4 minutes).
For the coding and the value range, see the GPRS Timer 2 IE in 3GPP TS 24.008 Table
10.5.163/3GPP TS 24.008 [12]. See also 3GPP TS 23.682 [153], 3GPP TS 23.060 [10]
and 3GPP TS 23.401 [154].
• SARA-R4 - The factory-programmed value is 6 s. The default value is "00000000".
14.7.4î™–î™–î™–î™–Notes
• The <Requested_Periodic_RAU> and <Requested_GPRS_READY_timer> parameters are not supported.
SARA-R4
• <mode>= 2 is not supported.
• Reboot the module after enabling the Power Save Mode in order to enter the PSM state.
• The PSM mode cannot be enabled with a PIN enabled UICC card.
