Electronic device and method for switching electronic device between dual standby mode and single standby mode

1. An electronic device comprising:

an embedded subscriber identity module (eSIM) embedded in the electronic device, the eSIM being configured to store a first profile associated with a first communication service;

a physical SIM (pSIM) configured such that a SIM card is capable of being removably attached thereto or capable of being inserted thereinto, the pSIM being configured to store a second profile associated with a second communication service; a communication processor configured to control the eSIM and the pSIM; and a processor configured to:

receive a signal indicating switching from a dual standby mode, in which the first communication service and the second communication service are both available, to a single standby mode, in which the first communication service is unavailable and the second communication service is available;

disable a local profile assistant in device (LPAd) configured to control the eSIM in response to receiving the signal;

delete a task associated with the eSIM in response to completion of disabling the LPAd;

request deactivating of a protocol stack corresponding to the eSIM in response to deleting the task; and

reset the communication processor in response to deactivating the protocol stack.

2. The electronic device of claim 1 , wherein the processor is further configured to disable a local user interface (LUI) configured to control a user interface to disable an operation of displaying a user interface associated with management of the first profile.

3. The electronic device of claim 1 , wherein the processor is further configured to disable a radio interface layer (RIL) comprised in a hardware abstraction layer (HAL), wherein the RIL is configured to transmit or receive data to or from a modem while deleting the task associated with the eSIM.

4. The electronic device of claim 1 , wherein the processor is further configured to not upload the task associated with the eSIM in memory when the electronic device is rebooted after the task associated with the eSIM is removed.

5. The electronic device of claim 1 , wherein the processor is further configured to control the LPAd to disable a remaining component other than an event receiver configured to receive a signal indicating switching to the dual standby mode.

6. The electronic device of claim 5 , wherein the processor is further configured to:

switch from a disabled state to an enabled state of the LPAd in response to receiving the signal indicating switching to the dual standby mode,

generate a task associated with the eSIM, and

activate the first communication service based on the generated task.

7. The electronic device of claim 6 , wherein the processor is further configured to:

activate a local user interface (LUI) configured to manage a user interface associated with management of the first profile, and

generate a task associated with the eSIM in response to reception of user input, on the user interface, for selecting the first profile.

8. The electronic device of claim 7 , wherein the processor is further configured to control the LUI to provide a user interface for selecting one of a plurality of profiles stored in the eSIM.

9. The electronic device of claim 1 , wherein the processor is further configured to deactivate the protocol stack to prevent reference to identification information corresponding to the eSIM from being made.

10. The electronic device of claim 1 , wherein the deleted task is comprised in a framework layer of the processor.

11. A method of operating an electronic device, the method comprising:

receiving a signal indicating switching from a dual standby mode, in which a first communication service and a second communication service are both available, to a single standby mode, in which the second communication service is available;

disabling a local profile assistant in device (LPAd) configured to control an embedded subscriber identity module (eSIM) configured to store a first profile associated with the first communication service in response to receiving the signal;

deleting a task associated with the eSIM in response to completion of disabling the LPAd;

deactivating a protocol stack corresponding to the eSIM in response to deleting the task; and

resetting a communication processor configured to control the eSIM in response to deactivating the protocol stack.

12. The method of claim 11 , further comprising:

disabling a local user interface (LUI) configured to control a user interface to disable an operation of displaying a user interface associated with management of the first profile.

13. The method of claim 11 , further comprising:

disabling a radio interface layer (RIL) comprised in a hardware abstraction layer (HAL), wherein the RIL is configured to transmit or receive data to or from a modem while deleting the task associated with the eSIM.

14. The method of claim 11 , further comprising:

performing control such that the task associated with the eSIM is not uploaded in memory when the electronic device is rebooted after the task associated with the eSIM is removed.

15. The method of claim 11 , further comprising:

controlling the LPAd to disable a remaining component other than an event receiver configured to receive a signal indicating switching to the dual standby mode.

16. The method of claim 15 , further comprising:

switching from a disabled state of the LPAd to an enabled state thereof in response to receiving the signal indicating switching to the dual standby mode;

generating a task associated with the eSIM; and

activating the first communication service based on the generated task.

17. The method of claim 16 , further comprising:

activating a local user interface (LUI) configured to manage a user interface associated with management of the first profile; and

generating a task associated with the eSIM in response to reception of user input, on the user interface, for selecting the first profile.

18. The method of claim 17 , further comprising:

controlling the LUI to provide a user interface for selecting one of a plurality of profiles stored in the eSIM.

19. The method of claim 11 , further comprising:

deactivating the protocol stack to thereby prevent reference to identification information corresponding to the eSIM.

20. The method of claim 11 , wherein the deleted task is comprised in a framework layer of the processor.
