Abstract

A method and a terminal device for keeping a subscriber identity module card in a standby state, where the method for keeping a subscriber identity module card in a standby state includes receiving, by a terminal device, an enabling request, where the enabling request is used for requesting simultaneous standby of a first subscriber identity module card and a second subscriber identity module card; invoking a third-party invocation interface provided by an operating system of the terminal device; performing interaction with a subscriber identity module card control module, so as to complete a network access process of the first subscriber identity module card on the basis of a data file of the first subscriber identity module card; and keeping the first subscriber identity module card and the second subscriber identity module card in a standby state at the same time according to the enabling request.

Claims

1. A method, comprising:

accessing, by a terminal device, a first network via a first subscriber identity module (SIM) card implemented on a basis of hardware in the terminal device;

receiving, by the terminal device, an enabling request, wherein the enabling request is used for enabling standby of a second SIM card implemented on a basis of software; and

performing, by the terminal device, a second network access process of the second SIM card based on a third-party interface on a basis of an operating system of the terminal device to implement a simultaneous standby of the first SIM card and the second SIM card in the terminal device.

2. The method of claim 1, further comprising displaying, by the terminal device, a user interface comprising information associated with the second SIM card and a button configured to switch on or off the second SIM card.

3. The method of claim 2, wherein the information associated with the second SIM card comprises region information of the terminal device.

4. The method of claim 1, wherein the third-party interface comprises a radio interface layer (RI L) interface.

5. The method of claim 1, wherein the operating system comprises an ANDROID system.

6. The method of claim 1, further comprising receiving, by the terminal device, a selecting operation from a user of the terminal device.

7. The method of claim 6, further comprising displaying, by the terminal device, a button associated with the selecting operation.

8. The method of claim 1, further comprising downloading, by the terminal device, a data file associated with the first SIM card from a network service provider.

9. A terminal device, comprising:

a memory comprising instructions; and

a processor coupled to the memory, wherein the instructions cause the processor to be configured to;

access a first network by a first subscriber identity module (SIM) card implemented on a basis of hardware in the terminal device;

receive an enabling request, wherein the enabling request is used for enabling standby of a second SIM card implemented on a basis of software; and

perform a second network access process of the second SIM card based on a third-party interface on a basis of an operating system of the terminal device to implement a simultaneous standby of the first SIM card and the second SIM card in the terminal device.

10. The terminal device of claim 9, wherein the instructions further cause the processor to be configured to display a user interface comprising information associated with the second SIM card and a button configured to turn on or turn off the second SIM card.

11. The terminal device of claim 10, wherein the information associated with the second SIM card comprises region information of the terminal device.

12. The terminal device of claim 9, wherein the third-party interface comprises a radio interface layer (RIL) interface.

13. The terminal device of claim 9, wherein the operating system comprises an ANDROID system.

14. The terminal device of claim 9, wherein the instructions further cause the processor to be configured to receive a selecting operation from a user of the terminal device.

15. The terminal device of claim 14, wherein the instructions further cause the processor to be configured to display a button associated with the selecting operation.

16. The terminal device of claim 9, wherein the instructions further cause the processor to be configured to download a data file associated with the first SIM card from a network service provider.
