Both features require a negotiation with the network to be enabled. The negotiation
happens during the Attach procedure and the Tracking Area Update (TAU).
8.2 PSM script
The module supports 3GPP command AT+CPSMS and custom Telit command AT#CPSMS
that simplifies and improve PSM management.
On ME910C1 and ML865C1:
AT#CPSMS=[<mode>[,<ReqPeriodicRAU>[,<ReqGPRSreadyTimer>[,<ReqPeriodicTAU
>[,<ReqActiveTime>]]]]]
The set command controls the setting of the UEs power saving mode (PSM) parameters. The
command controls whether the UE wants to apply PSM or not, as well as the requested
extended periodic RAU value and the requested GPRS READY timer value in GERAN, the
requested extended periodic TAU value in E-UTRAN and the requested Active Time value.
Find the relevant parameters below.
<ReqPeriodicTAU> : requested extended periodic TAU value (T3412) to be allocated to the
UE in E-UTRAN. Parameter expressed in secconds.
<ReqActiveTime> : requested Active Time value (T3324) to be allocated to the UE. Parameter
expressed in seconds.
AT#CPSMS?
Read command presents the current CPSMS configuration returned by the network, in the
format:
#CPSMS: <status>[,<T3324>,<T3412 or T3412EXT>]
