Parameter
2.18. AT+CPSMS Power Saving Mode Setting
The write 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 TAU
value in E-UTRAN and the requested Active Time value. See the unsolicited result codes provided by
commands +CEREG for the Active Time value and the extended periodic TAU value that are allocated to
the UE by the network in E-UTRAN.
A special form of the command can be given as +CPSMS=2. In this form the use of PSM will be disabled
and data for all parameters in the command +CPSMS will be removed or, if available, set to the
manufacturer specific default values.
The read command returns the current parameter values.
The test command returns the supported <mode>s and the value ranges for the requested extended
periodic TAU value in E-UTRAN and the requested Active Time value as compound values.
