Abstract

Disclosed herein is a method for managing an embedded Subscriber Identity Module (eSIM) profile. The method may include installing a common profile in multiple devices to perform provisioning, selecting a representative device from among the multiple devices, establishing a communication channel in the representative device, receiving, by the representative device, profile information for the multiple devices from a server, and transferring, by the representative device, the profile information to the respective devices.

Claims (27)

1 . A method for managing an embedded Subscriber Identity Module (eSIM) profile, comprising:

installing a common profile in multiple devices to perform provisioning;

selecting a representative device from among the multiple devices and establishing a communication channel in the representative device;

receiving, by the representative device, profile information for the multiple devices from a server; and

transferring, by the representative device, the profile information to respective devices;

wherein, when a device of the multiple devices makes a request for a profile download to the representative device, the representative device transfers profile information about the representative device to the device that makes the request for the profile download.

2 . The method of claim 1 , wherein the profile information is transferred to the respective devices using information of the common profile.

3 . The method of claim 2 , wherein the profile information is encrypted or signed with a secret key of the common profile.

4 . The method of claim 1 , wherein the server receives information for creating a profile and creates the profile using the information.

5 . The method of claim 1 , wherein the server includes Subscription Manager Data Preparation (SM-DP) and Subscription Manager Secure Routing (SM-SR).

6 . The method of claim 5 , wherein the SM-DP creates a profile and transfers the created profile to the SM-SR.

7 . The method of claim 6 , wherein the SM-SR transfers the profile to an embedded universal IC card (eUICC) of the representative device, and the eUICC installs the profile.

8 . The method of claim 1 , wherein the device that makes the request for the profile download installs the profile information received from the representative device.

9 . The method of claim 8 , wherein the device that makes the request for the profile download transfers changed profile information to the server.

10 . An apparatus for managing an embedded Subscriber Identity Module (eSIM) profile, comprising:

memory in which a control program for managing an eSIM profile is stored; and

a processor for executing the control program stored in the memory,

wherein the processor installs a common profile in multiple devices to perform provisioning, selects a representative device from among the multiple devices, establishes a communication channel in the representative device, enables the representative device to receive profile information for the multiple devices from a server, and enables the representative device to transfer the profile information to respective devices;

wherein the processor performs control such that, when a device of the multiple devices makes a request for a profile download to the representative device, the representative device transfers profile information about the representative device to the device that makes the request for the profile download.

11 . The apparatus of claim 10 , wherein the processor transfers the profile information to the respective devices using information of the common profile.

12 . The apparatus of claim 11 , wherein the profile information is encrypted or signed with a secret key of the common profile.

13 . The apparatus of claim 10 , wherein the processor performs control such that the server receives information for creating a profile and creates the profile using the information.

14 . The apparatus of claim 10 , wherein the server includes Subscription Manager Data Preparation (SM-DP) and Subscription Manager Secure Routing (SM-SR).

15 . The apparatus of claim 14 , wherein the processor performs control such that the SM-DP creates a profile and transfers the created profile to the SM-SR.

16 . The apparatus of claim 15 , wherein the processor performs control such that the SM-SR transfers the profile to an embedded universal IC card (eUICC) of the representative device and such that the eUICC installs the profile.

17 . The apparatus of claim 10 , wherein the processor performs control such that the device that makes the request for the profile download installs the profile information received from the representative device.

18 . The apparatus of claim 17 , wherein the processor performs control such that the device that makes the request for the profile download transfers changed profile information to the server.
