Abstract

Disclosed in embodiments of the present invention is a method for reducing power consumption of a terminal, comprising: receiving a suspend command of a terminal; and storing status information of a universal integrated circuit card (UICC). Also disclosed in the embodiments of the present invention are a device for reducing power consumption of a terminal, and a smart card.

First claim

What is claimed is:

1. A method for reducing power consumption of a terminal, comprising:
receiving a suspend command of the terminal; and
storing status information of a Universal Integrated Circuit Card UICC;
wherein before the receiving the suspend command of the terminal, the method further comprises:
modifying a UICC service table to add instruction information of instructing the suspend command and a recovery command into the UICC service table; and
sending the modified UICC service table to the terminal.

2. The method according to claim 1 , further comprising:
sending a suspend response command to the terminal, the suspend response command comprising a suspend time duration and a keyword of recovering the status information of the UICC.

3. The method according to claim 1 , wherein the modifying the UICC service table is: to add first instruction information and second instruction information after the UICC service table; wherein, the first instruction information instructs a UICC suspend command, and the second instruction information instructs a UICC recovery command.

4. The method according to claim 1 , wherein the status information of the UICC further comprises:
a status of a Network Access Application NAA selected by each logical channel of the UICC, a security condition of each network access application of the UICC, a basic file selected by each logical channel of the UICC, and at least one of a corresponding record and a status of an application toolbox of the UICC.

5. A method for reducing power consumption of a terminal, comprising:
receiving a recovery command of the terminal, the recovery command comprising: a keyword of recovering status information of a UICC;
switching on and initializing the UICC;
when the UICC confirms to a recovery condition and the status information of the UICC exists, matching the keyword of recovering the status information of the UICC in the recovery command with the status information of the UICC;
when the matching is successful, recovering according to the status information of the UICC corresponding to the keyword, and sending response information of successful recovery to the terminal; and
deleting the status information of the UICC corresponding to the keyword.

6. The method according to claim 5 , wherein the confirming to the recovery condition comprises:
the UICC not performing an initialization process, the UICC not receiving a terminal configuration command, and the UICC not performing a command to select a base file name.

7. A method for reducing power consumption of a terminal, comprising:
when a UICC confirms to a suspend condition, sending a suspend command to the UICC;
receiving a suspend response command sent by the UICC; and
switching off the UICC according to the suspend response command;
wherein before the sending the suspend command to the UICC, the method further comprises:
acquiring a modified UICC service table sent by the UICC;
determining whether the UICC supports the suspend command and a recovery command according to the modified UICC service table; and
when both the UICC and the terminal support the suspend command and the recovery command, performing a subsequent suspend operation and a subsequent recovery operation.

8. The method according to claim 7 , wherein the suspend response command comprises a suspend time duration and a keyword of recovering status information of the UICC.

9. The method according to claim 7 , further comprising:
when the UICC confirms to a recovery condition, sending a recovery command to the UICC;
switching on the UICC; and
receive response information sent by the UICC.

10. The method according to claim 9 , wherein the recovery command comprises: a keyword of recovering status information of the UICC.

11. An apparatus for reducing power consumption of a terminal, comprising:
a receiving module configured to receive a suspend command of the terminal;
a processing module configured to store status information of a Universal Integrated Circuit Card UICC;
a modifying module configured to modify a UICC service table to add instruction information of instructing the suspend command and a recovery command into the UICC service table; and
a sending module configured to send the modified UICC service table to the terminal.

12. The apparatus according to claim 11 , wherein:
the sending module is further configured to send a suspend response command to the terminal, the suspend response command comprising a suspend time duration and a keyword of recovering the status information of the UICC.

13. An apparatus for reducing power consumption of a terminal, comprising:
a receiving module configured to receive a recovery command of the terminal, the recovery command comprising: a keyword of recovering status information of a UICC;
an initializing module configured to switch on and initialize the UICC;
a matching module configured to, when the UICC confirms to a recovery condition and the status information of the UICC exists, match the keyword of recovering the status information of the UICC in the recovery command with the status information of the UICC;
a recovery module configured to, when the matching the keyword of recovering the status information of the UICC in the recovery command with the status information of the UICC is successful, recover according to the status information of the UICC corresponding to the keyword, and send response information of successful recovery to the terminal; and
a deleting module configured to delete the status information of the UICC corresponding to the keyword.

14. An apparatus for reducing power consumption of a terminal, comprising:
a sending module configured to, when a UICC confirms to a suspend condition, send a suspend command to the UICC;
a receiving module configured to receive a suspend response command sent by the UICC;
a switching-off module configured to switch off the UICC according to the suspend response command;
an acquisition module configured to acquire a modified UICC service table sent by the UICC;
a determining module configured to determine whether the UICC supports the suspend command and the recovery command according to the modified UICC service table; and
a processing module configured to, when both the UICC and the terminal support the suspend command and the recovery command, perform a subsequent suspend operation and a subsequent recovery operation.

15. The apparatus according to claim 14 , further comprising:
a sending module configured to, when the UICC confirms to a recovery condition, send a recovery command to the UICC;
a switching-on module configured to switch on the UICC; and
a receiving module configured to receive response information sent by the UICC.

16. A smart card, wherein the smart card comprises a UICC implementing the methods according to any one of claims claims 1 , 2 , and 3 - 6 .
