An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in 3GPP TR 21.905 1. 4 Use c
31、ases 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 i
32、mpossible 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 tracki
33、ng, 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 a
34、re 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
35、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 cas
36、e, 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-define
37、d 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 co
38、ntrolled 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 consumptio
39、n 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
40、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. ETSI ETSI TR 131 970 V14.0.0 (2017-06)73GPP TR 31.970 version 14.0.0 Release 145 Power considerations related to the UICC 5.1 Causes of power cons
41、umption 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 normally occurs in bursts. Examples of this include: The ME reads configuration parameters set by the MN
42、O and stored in the UICC The ME performs authentication command The ME reads data stored in the UICC by the end user (i.e. phonebook or SMS) The ME writes data to the UICC Proactive sessions, as defined in TS 31.111 5 Toolkit events, as defined in TS 31.111 5 During the rest of the time, the UICC is
43、 not actively used by the terminal. There are three distinct causes of power consumption that are related to the presence of the UICC that contains a USIM when not actively used. 5.1.2 Presence detection polling The presence detection mechanism is defined in ETSI TS 102 221 6 clause 14.5.2 and refer
44、enced by 3GPP TS 31.101 3: If an application present on the UICC has the requirement to ensure that the UICC has not been removed during a card session the following procedure applies. The terminal sends, at frequent intervals, a STATUS command on the UICC-terminal interface. The STATUS command shal
45、l be issued within a period of inactivity on the UICC-terminal interface. . This procedure shall be used in addition to a mechanical or other device used to detect the removal of a UICC. According to TS 31.102 4 clause 5.1.9, presence detection polling is required by the USIM only in case of a call,
46、 including active PDP context, and can be suspended if the ME has not exchanged any data with the network within a 30s period of inactivity on the UICC-ME interface. The ME may suspend the UICC presence detection based on STATUS commands in case it has an active PDP context or an active EPS bearer c
47、ontext, but has not exchanged any data with the network within a 30s period of inactivity on the UICC-ME interface, and resume it as soon as data is exchanged with the network, sending immediately a new STATUS command. As a consequence of changes agreed in Release 12 as part of the MTCe-UEPCOP-CT Wo
48、rk Item, the presence detection polling is not a concern for devices that are not actively exchanging data with the network. 5.1.3 Proactive polling The proactive polling mechanism is defined in ETSI TS 102 221 6 clause 14.6.2 and referenced by 3GPP TS 31.101 3: During idle mode the terminal shall s
49、end STATUS commands to the UICC at intervals no longer than the interval negotiated with the UICC (see TS 102 223 7). During a call the UICC presence detection applies. The default value for the proactive polling is the same as for the presence detection procedure. The interval of the proactive polling can be negotiated between UICC and ME: the UICC can completely disable proactive polling using the POLLING OFF proactive command, defined in TS 31.111 5; ETSI ETSI TR 131 970 V14.0.0 (2017-06)83GPP TR 31.
