Parameter Type Description
<mode> Number Indication to disable or enable the use of PSM in the UE. Allowed values:
0 (default 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.
The factory-programmed value depends on the module series:
SARA-R4 / SARA-N4 - 0
<Requested_
Periodic_RAU>
String One byte in an 8 bit format. Requested extended periodic RAU value (T3312_ext) to
be allocated to the UE in GERAN/UTRAN. The requested extended periodic RAU 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 [12]. See also 3GPP TS 23.682 [128] and 3GPP TS 23.060 [10]. The
factory-programmed value is:
SARA-R412M -"00011000" (4 hours)
<Requested_GPRS_
READY_timer>
String One byte in an 8 bit format. Requested GPRS READY timer value (T3314) to be
allocated to the UE in GERAN/UTRAN. The requested GPRS READY timer value is
coded as one byte (octet 2) of the GPRS Timer information element coded as bit
format (e.g. "01000011" equals 3 decihours or 18 minutes). For the coding and the
value range, see the GPRS Timer IE in 3GPP TS 24.008 table 10.5.172/3GPP TS 24.008
[12]. See also 3GPP TS 23.060 [10]. The factory-programmed value is:
SARA-R412M - "00001010" (20 s)
<Requested_
Periodic_TAU>
String One byte in an 8 bit format. Requested extended periodic TAU value (T3412_ext) to be
allocated to the UE 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 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
[128] and 3GPP TS 23.401 [129].

SARA-R410M-83B / SARA-R412M - For the factory-programmed and default value,
see Mobile Network Operator profiles.
SARA-R404M / SARA-R410M-01B / SARA-N4 - The factory-programmed value is "10
000101" (150 s). The default value is "01100000" (0 s).
<Requested_Active_
Time>
String One byte in an 8 bit format. Requested Active Time value (T3324) to be allocated to
the UE in GERAN/UTRAN or in EUTRAN. 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 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
[128], 3GPP TS 23.060 [10] and 3GPP TS 23.401 [129].

SARA-R410M-83B / SARA-R412M - For the factory-programmed and default value,
see Mobile Network Operator profiles.
SARA-R404M / SARA-R410M-01B / SARA-N4 - The factory-programmed value is "0
0000011" (6 s). The default value is "00000000" (0 s).
15.2.4Notes
SARA-R4 / SARA-N4
<mode>= 2 (PSM use disabled and reset all parameters for PSM to factory-programmed values) is not
supported. To reset all the PSM parameters to factory-programmed values (see Mobile Network Operator
profiles), follow the procedure described in the +UMNOPROF AT command description.
The module converts the <Requested_Periodic_RAU>, <Requested_GPRS_READY_timer>, <Requested_
Periodic_TAU>, <Requested_Active_Time> parameters bitmasks configured with the set command
to equivalent ones which represent the same value. The new bitmasks use the smallest unit of
measurement possible to represent the timer value. See Table 14 for additional examples.
Command Response Description
AT+CPSMS=1,,,"00000010","000000
10"
OK Set <Requested_Periodic_TAU> to
"00000010" corresponding to 20
minutes (=10 minutes * 2)
