Method for providing SIM profile in eUICC environment and devices therefor

1. A method of providing a subscriber identification module (SIM) profile to an embedded universal integrated circuit card (eUICC) device, comprising:

downloading a SIM profile application selected by a user who uses the eUICC device from an app store;

executing the SIM profile application in the eUICC device and installing the application in the eUICC device; and

accessing of the eUICC device having the SIM profile application installed therein to an operator server, and authenticating the eUICC device based on SIM profile information corresponding to the SIM profile application,

wherein in the executing of the SIM profile application in the eUICC device and installing of the application in the eUICC device, an initial SIM profile is replaced with the selected SIM profile when the downloaded SIM profile application is executed,

wherein the initial SIM profile includes access information of the app store and is included in the eUICC device, the initial SIM profile being an existing SIM profile when the eUICC device is released, and

wherein the app store and the operator server are separate entities.

2. The method of claim 1 , wherein in the downloading of the SIM profile application selected by the user who uses the eUICC device from the app store, user unique identification information is used to access the app store via a local network.

3. The method of claim 1 , wherein in the downloading of the SIM profile application selected by the user who uses the eUICC device from the app store, a user interface (UI) or user experience (UX) provided by the app store is used.

4. The method of claim 3 , wherein in the downloading of the SIM profile application selected by the user who uses the eUICC device from the app store, the operator information is provided and at least one operator SIM profile application is listed using a category item of the app store.

5. The method of claim 1 , further comprising distributing, by the operator server, the SIM profile application in a form of an application to the app store.

6. An embedded universal integrated circuit card (eUICC) device, comprising:

a network connection unit configured to access an app store via a local network;

a subscriber identification module (SIM) profile storage configured to store a SIM profile application that is downloaded by accessing the app store through the network connection unit; and

an authentication requesting unit configured to access an operator server based on SIM profile information,

wherein the SIM profile storage previously stores an initial SIM profile including access information of the app store, the initial SIM profile being an existing SIM profile when the eUICC device is released.

7. The device of claim 6 , wherein the network connection unit accesses the app store via the local network using user unique identification information.

8. The device of claim 6 , wherein in the SIM profile storage, the initial SIM profile is replaced with the SIM profile and is installed when the downloaded SIM profile application is executed.

9. The device of claim 8 , wherein the authentication requesting unit requests authentication of the eUICC device by accessing the operator server based on the replaced SIM profile information.

10. An operator server, comprising:

a subscriber identification module (SIM) profile distributor configured to distribute a SIM profile application to an app store; and

a user authentication unit configured to perform authentication procedures in response to an access and authentication request of an embedded universal integrated circuit card (eUICC) device in which a SIM profile application provided by the app store is downloaded and installed,

wherein the eUICC device includes an initial SIM profile which includes access information of the app store, the initial SIM profile being an existing SIM profile when the eUICC device is released.

11. The operator server of claim 10 , wherein the SIM profile distributor uploads the SIM profile application to the app store using a user interface (UI) provided by the app store.

12. The operator server of claim 10 , wherein the user authentication unit performs the authentication procedures based on personal information associated with authentication and operator information included in a SIM profile of the eUICC device.
