Abstract

An application processing method and apparatus for an embedded universal integrated circuit card (eUICC) are disclosed. The method includes: activating, by a terminal device, an embedded universal integrated circuit card (eUICC); and selecting, by the terminal device, an Issuer Security Domain Root (ISD-R) application on the eUICC during an initialization process of the eUICC, to maintain a session between the terminal device and the eUICC. The session between the terminal device and the eUICC can be maintained during the initialization process of the eUICC.

First claim

What is claimed is:

1. An application processing method for an embedded universal integrated circuit card, comprising:
activating, by an apparatus, an embedded universal integrated circuit card (eUICC);
selecting, by the apparatus, an Issuer Security Domain Root (ISD-R) application on the eUICC during an initialization process of the eUICC; and
obtaining, by the apparatus, eUICC information.

2. The method according to claim 1 , wherein after the obtaining, by the apparatus, eUICC information, the method further comprises:
sending, by the apparatus, the eUICC information to a Local Profile Assistant (LPA) module.

3. The method according to claim 1 , wherein the eUICC information comprises:
at least one of eUICC identity information, information about a profile on the eUICC, or eUICC capability information.

4. The method according to claim 3 , wherein when the eUICC information comprises the information about the profile on the eUICC, the profile on the eUICC comprises:
at least one of information about all profiles on the eUICC, information about an enabled profile on the eUICC, information about a disabled profile on the eUICC, information about a preconfigured-type profile on the eUICC, information about a test-type profile on the eUICC, information indicating that there is no operable profile on the eUICC, and information indicating that there is no enabled profile on the eUICC.

5. The method according to claim 3 , wherein when the eUICC information comprises the eUICC capability information, the eUICC capability information comprises:
at least one of a protocol version number supported by the eUICC, an identifier of a key supported by the eUICC, a category of the eUICC, or capability information of a LPA module supported by the eUICC.

6. The method according to claim 5 , wherein when the eUICC capability information comprises the protocol version number supported by the eUICC, the method further comprises:
obtaining, by the apparatus by using the LPA module, the protocol version number supported by the eUICC, and determining, based on the protocol version number supported by the eUICC, a protocol version number used for communication between the LPA module and the eUICC.

7. The method according to claim 5 , wherein the ISD-R application is selected by a modem of the apparatus.

8. The method according to claim 5 , wherein when the eUICC capability information comprises the capability information of the LPA supported by the eUICC, the method further comprises:
after the LPA module obtains the capability information of the LPA supported by the eUICC, determining, by the LPA module based on the capability information of the LPA module, whether to activate the LPA module.

9. The method according to claim 1 , wherein the method further comprises:
if there is no enabled profile on the eUICC, maintaining a session between the apparatus and the eUICC.

10. The method according to claim 1 , wherein after the selecting, by the apparatus, the ISD-R application on the eUICC, the method further comprises: terminating, by the apparatus, the ISD-R application.

11. The method according to claim 1 , wherein the terminating, by the apparatus, the ISD-R application comprises:
after the apparatus completes initialization of the eUICC, terminating, by the apparatus, the ISD-R application.

12. An apparatus, comprising at least one processor, and a memory, wherein a set of program code is stored in the memory, and the program code instructs the at least one processor to perform operations comprising:
activating an embedded universal integrated circuit card (eUICC);
selecting an Issuer Security Domain Root (ISD-R) application on the eUICC during an initialization process of the eUICC; and
obtaining eUICC information.

13. The apparatus according to claim 12 , wherein the operations comprise:
sending the eUICC information to a Local Profile Assistant (LPA) module.

14. The apparatus according to claim 12 , wherein the eUICC information comprises:
at least one of eUICC identity information, information about a profile on the eUICC, or eUICC capability information.

15. The apparatus according to claim 14 , wherein when the eUICC information comprises the information about the profile on the eUICC, the profile on the eUICC comprises:
at least one of information about all profiles on the eUICC, information about an enabled profile on the eUICC, information about a disabled profile on the eUICC, information about a preconfigured-type profile on the eUICC, information about a test-type profile on the eUICC, information indicating that there is no operable profile on the eUICC, and information indicating that there is no enabled profile on the eUICC.

16. The apparatus according to claim 14 , wherein when the eUICC information comprises the eUICC capability information, the eUICC capability information comprises:
at least one of a protocol version number supported by the eUICC, an identifier of a key supported by the eUICC, a category of the eUICC, or capability information of a local profile assistant (LPA) module.

17. The apparatus according to claim 16 , wherein when the eUICC capability information comprises the protocol version number supported by the eUICC, the operations comprise:
obtaining, by using the LPA module, the protocol version number supported by the eUICC, and determining, based on the protocol version number supported by the eUICC, a protocol version number used for communication between the LPA module and the eUICC.

18. The apparatus according to claim 16 , wherein the operations further comprise:
if there is no enabled profile on the eUICC, maintaining a session between the apparatus and the eUICC.

19. The apparatus according to claim 16 , wherein when the eUICC capability information comprises the capability information of the LPA supported by the eUICC, the operations comprise:
after obtaining the capability information of the LPA supported by the eUICC, determining, based on the capability information of the LPA supported by the eUICC, whether to activate the LPA.

20. The apparatus according to claim 16 , wherein the operations further comprise:
after completing initialization of the eUICC, terminating the ISD-R application.
