Abstract

A method to converge a 5^th-Generation (5G) communication system to support higher data rates beyond a 4^th-Generation (4G) system with a technology for Internet of Things (IoT) is provided. This disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, e.g., smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security/safety services.

A method of transmitting and updating modified information to a profile management server (SM-SR) when a modification is made to information stored in an eUICC that is a security module embedded in a terminal is provided. The present disclosure relates to a method to update a profile management server to enable profile management using OTA technology when a modification is made to data stored in an MNO-SD that is a unique area of each mobile network operator of a profile stored in an eUICC.

Claims

1. A method of updating a profile management server of a terminal having a universal integrated circuit card (eUICC) embedded therein, the method comprising:

determining whether information stored in a secured area of a profile stored in the eUICC is modified;

creating an update request message of the profile management server that includes the modified information when the determination result shows that the information stored in the secured area has been modified; and

transmitting the created update request message to the profile management server, wherein the information stored in the secured area is configured to be modified using a unique encryption key of a mobile network operator (MNO) of the profile.

2. The method of claim 1, wherein the information stored in the secured area is at least one of a mobile subscriber issuer security domain number (MSISDN), an international mobile subscriber identity (IMSI), and an integrated circuit card identity (ICCID) of the profile stored in the eUICC.

3. The method of claim 1, wherein the creating of the update request message of the profile management server comprises:

creating an update request message comprising one of the modified information, a partial area of the profile including the modified information, and the profile including the modified information.

4. A terminal having an embedded universal integrated circuit card (eUICC) embedded therein for updating a profile management server, the terminal comprising:

a communication unit configured to perform data communication; and

a controller configured to;

determine whether information stored in a secured area of a profile stored in the eUICC is modified,

create an update request message of the profile management server that includes the modified information when the determination result shows that the information stored in the secured area has been modified, and

transmit the created update request message to the profile management server, wherein the information stored in the secured area is configured to be modified using a unique encryption key of a mobile network operator (MNO) of the profile.

5. The terminal of claim 4, wherein the information stored in the secured area is at least one of a mobile subscriber issuer security domain number (MSISDN), an international mobile subscriber identity (IMSI), and an integrated circuit card identity (ICCID) of the profile stored in the eUICC.

6. The terminal of claim 4, wherein the controller is configured to create an update request message comprising one of the modified information, a partial area of the profile including the modified information, and the profile including the modified information.

7. A method of updating a server for managing a profile stored in an embedded universal integrated circuit card (eUICC) embedded in a terminal, the method comprising:

receiving an update request message of profile related information;

extracting the profile related information included in the received update request message; and

renewing pre-stored profile related information based on the extracted profile related information, wherein the profile related information is stored in a secured area of the profile and the secured area is changed using a unique encryption key of a mobile network operator (MNO).

8. The method of claim 7, wherein the update request message is received from one of the mobile network operator (MNO), a server creating the profile according to a request of the MNO, and the eUICC.

9. The method of claim 7, wherein the profile related information is at least one of a mobile subscriber issuer security domain number (MSISDN), an international mobile subscriber identity (IMSI), and an integrated circuit card identity (ICCID) of the profile stored in the eUICC.

10. The method of claim 7, wherein the update request message comprises one of the profile related information, a partial area of a profile including the profile related information, and the profile including the profile related information.

11. A server for managing a profile stored in an embedded universal integrated circuit card (eUICC) embedded in a terminal, the server comprising:

a communication unit configured to perform data communication; and

a controller configured to;

receive an update request message of profile related information,

extract the profile related information included in the received update request message, and

renew pre-stored profile related information based on the extracted profile related information, wherein the profile related information is stored in a secured area of the profile and the secured area is changed using a unique encryption key of a mobile network operator (MNO).

12. The server of claim 11, wherein the update request message is received from one of the mobile network operator (MNO), a server creating the profile according to a request of the MNO, and the eUICC.

13. The server of claim 11, wherein the profile related information is at least one of a mobile subscriber issuer security domain number (MSISDN), an international mobile subscriber identity (IMSI), and an integrated circuit card identity (ICCID) of the profile stored in the eUICC.

14. The server of claim 11, wherein the update request message comprises one of the profile related information, a partial area of a profile including the profile related information, and the profile including the profile related information.

15. A method of updating a profile management server by a server for creating a profile for an embedded universal integrated circuit card (eUICC) embedded in a terminal, the method comprising:

receiving an update request message for profile related information of the profile management server from a mobile network operator (MNO); and

forwarding the received update request message to the profile management server, wherein the update request message comprises modified profile related information, and wherein the profile related information is configured to be modified using a unique encryption key of the MNO.

16. The method of claim 15, wherein the modified profile related information is at least one of a mobile subscriber issuer security domain number (MSISDN), an international mobile subscriber identity (IMSI), and an integrated circuit card identity (ICCID) of a profile stored in the eUICC.

17. The method of claim 15, wherein the update request message comprises one of the modified profile related information, a partial area of a profile including the modified profile related information, and the profile including the modified profile related information.

18. A profile creation server for updating a profile management server of an embedded universal integrated circuit card (eUICC) embedded in a terminal, the profile creation server comprising:

a communication unit configured to perform data communication; and

a controller configured to;

receive an update request message for profile related information of the profile management server from a mobile network operator (MNO), and

forward the received update request message to the profile management server, wherein the update request message comprises modified profile related information, and wherein the profile related information is configured to be modified using a unique encryption key of the MNO.

19. The profile creation server of claim 18, wherein the modified profile related information is at least one of a mobile subscriber issuer security domain number (MSISDN), an international mobile subscriber identity (IMSI), and an integrated circuit card identity (ICCID) of a profile stored in the eUICC.

20. The profile creation server of claim 18, wherein the update request message comprises one of the modified profile related information, a partial area of a profile including the modified profile related information, and the profile including the modified profile related information.
