The set command configures the Universal Integrated Circuit Card (UICC)'s deactivation
behavior to save power.
Syntax:
%UICCPOWERSAVE=<mode>
The set command parameter and its defined values are the following:
- <mode>
- 0 – Default functionality.
- UICC is deactivated during Extended Discontinuous Reception (eDRX) only when it is allowed
by Elementary File for Administrative Data (EF-AD), the application PIN is disabled, and sleep
duration exceeds the minimum period, which is 1 min in ultra-low power mode and 5 min in
other power modes. Power saving mode is set with the %XDATAPRFL command.
- 1 – If deactivation is not allowed due to a condition mentioned in
<mode>
0, proactive polling intervals can be extended to align with the eDRX
sleep period regardless of the EF-AD content. If the polling interval exceeds the sleep
period, it remains unchanged.
- 2 – EF-AD, PIN state, and minimum deactivation time restrictions are bypassed. After
entering eDRX sleep, the UICC reactivates before the next RRC connection is
established.
- 3 – EF-AD, PIN state, and minimum deactivation time restrictions are bypassed. The
UICC can be deactivated when in RRC IDLE. The UICC reactivates before the next RRC
connection is established.
The following command example configures the deactivation of UICC when entering RRC IDLE
state:
AT%UICCPOWERSAVE=3
OK
