1 Scope
The present document has the objective to describe the power consumption caused by UICC when it is idle and
identify the potential solutions to allow the reduction or removal of the UICC power supply in order to save power
when the UICC is not required for long periods of time.
This document identifies conditions which might need to be applied to the UICC platform.

4 Use cases
Use cases are described in Annex A of TS 22.368 [8]. Some examples are copied below:
Extra Low Power Consumption Use Case
For high mobility case, tracking MTC devices such as animal tracking MTC devices in natural world with high
mobility require extra low power consumption because it is almost impossible to replace the battery or recharge the
battery for animal tracking MTC device. Compared to the tracking devices installed in the cars and trucks because
cars and trucks could generate electricity by themselves, extra low power consumption for these MTC devices is
required.
For cargo tracking, the cargo with a tracking MTC device could move very fast such as on a train or lorry and could
stand still such as in the dock before loading or unloading. It is not desired to either change its battery or replace
battery during the transport period, so extra low power consumption MTC devices are also required.
For prisoner tracking MTC devices are already used by police, prisoners will not cooperate with police and would
wish the MTC devices have flat batteries; therefore, extra low power consumption feature is required for these MTC
devices. For the tracking MTC devices of elder people who have memory problem, children or pets, even the
batteries of these MTC devices could be replaced or charged, however, considering the worst scenario – if they are
missing, it requires the MTC devices with extra low power consumption and long working time in order to find
them.
For low mobility case, the gas meter MTC devices must be battery powered. Extra low power consumption for gas
MTC devices is much more critical than electricity meters.
Extra Low Power Consumption with Time Controlled MTC Devices Use Case
Time Controlled MTC Devices which send or receive data only at certain pre-defined periods may be operated in
one or more modes that minimize power consumption.
An MTC Device may be operated in a mode where it is expected to receive non-periodic messages (e.g. emergency
messages or notifications of altered access period as with the MTC Feature Time Controlled outside the time
controlled periods. The MTC Device should minimize power consumption while in a mode to support this.
If the application requires the MTC Device to send or receive data within pre-defined periods and receive non-
periodic messages outside these periods, operation at the lowest possible power consumption level to extend battery
life should be achieved.
Such use cases justify the overall system requirement present in TS 22.368 [8]:
The system shall provide mechanisms to lower power consumption of MTC Devices.
Some solutions to lower the overall power consumption in such scenarios are already defined within 3GPP, as described
in TR 23.887 [9] clause 7. These include:
- Extended DRX cycle, introduced in Rel-13, as described in TS 23.682 [10] clause 4.5.13.
5 Power considerations related to the UICC
5.1 Causes of power consumption related to the UICC
5.1.1 Introduction
During the power cycle of the ME, there are only some short periods of time during which the UICC is actively used by
the terminal and that activity normal
