Abstract

A method, performed by a terminal, of negotiating an embedded universal integrated circuit card (eUICC) version in a wireless communication system includes: establishing a hypertext transfer protocol over secure socket layer (HTTPS) connection with a server transmitting eUICC information including information about the eUICC version to the server through the HTTPS connection; and receiving server information corresponding to the eUICC information from the server, wherein the information about the eUICC version includes a minimum eUICC version and a maximum eUICC version that are available when the terminal accesses the server.

First claim

What is claimed is:

1. A method, performed by a terminal, of negotiating an embedded universal integrated circuit card (eUICC) version in a wireless communication system, wherein an eUICC is a UICC that is removable or non-removable from the terminal, the method comprising:
establishing a hypertext transfer protocol over secure socket layer (HTTPS) connection with a server;
transmitting eUICC information comprising information about the eUICC version to the server through the HTTPS connection; and
receiving server information corresponding to the eUICC information from the server,
wherein the information about the eUICC version comprises a minimum eUICC version and a maximum eUICC version that are available when the terminal accesses the server.

2. The method of claim 1 , wherein the server information corresponding to the eUICC information comprises an error message,
wherein the method further comprises determining that the server does not support the eUICC version supported by the terminal.

3. The method of claim 1 , wherein the eUICC information comprises a list of all or some of functions defined by a protocol of the eUICC version.

4. The method of claim 3 , wherein the list is written by using a bitmap.

5. The method of claim 1 , further comprising performing an authentication process with the server based on the server information corresponding to the eUICC information.

6. A method, performed by a server, of negotiating an embedded universal integrated circuit card (eUICC) version in a wireless communication system, wherein an eUICC is a UICC that is removable or non-removable from a terminal, the method comprising:
establishing a hypertext transfer protocol over secure socket layer (HTTPS) connection with a terminal;
receiving eUICC information comprising information about the eUICC version from the terminal through the HTTPS connection; and
transmitting server information corresponding to the eUICC information to the terminal,
wherein the information about the eUICC version comprises a minimum eUICC version and a maximum eUICC version that are available when the terminal accesses the server.

7. The method of claim 6 , wherein the transmitting of the server information corresponding to the eUICC information comprises:
when the server supports both the minimum eUICC version and the maximum eUICC version or supports the maximum eUICC version, generating the server information comprising information about a server version corresponding to the maximum eUICC version.

8. The method of claim 7 , wherein the server information comprises a list of all or some of functions defined by a protocol of the server version.

9. The method of claim 8 , wherein the list is written by using a bitmap.

10. The method of claim 6 , wherein the transmitting of the server information corresponding to the eUICC information to the terminal comprises:
when the server supports the minimum eUICC version, generating the server information not comprising information about a server version.

11. A terminal negotiating an embedded universal integrated circuit card (eUICC) version in a wireless communication system, wherein an eUICC is a UICC that is removable or non-removable from the terminal, the terminal comprising:
a transceiver; and
at least one processor coupled with the transceiver and configured to:
establish a hypertext transfer protocol over secure socket layer (HTTPS) connection with a server;
transmit eUICC information comprising information about the eUICC version to the server through the HTTPS connection; and
receive server information corresponding to the eUICC information from the server,
wherein the information about the eUICC version comprises a minimum eUICC version and a maximum eUICC version that are available when the terminal accesses the server.

12. The terminal of claim 11 , wherein:
the server information corresponding to the eUICC information comprises an error message; and
the processor is configured to determine that the server does not support the eUICC version supported by the terminal.

13. The terminal of claim 11 , wherein the eUICC information comprises a list of all or some of functions defined by a protocol of the eUICC version.

14. The terminal of claim 13 , wherein the list is written by using a bitmap.

15. The terminal of claim 11 , wherein the processor is configured to perform an authentication process with the server based on the server information corresponding to the eUICC information.

16. A server negotiating an embedded universal integrated circuit card (eUICC) version in a wireless communication system, wherein an eUICC is a UICC that is removable or non-removable from a terminal, the server comprising:
a transceiver; and
at least one processor coupled with the transceiver and configured to:
establish a hypertext transfer protocol over secure socket layer (HTTPS) connection with a terminal;
receive eUICC information comprising information about the eUICC version from the terminal through the HTTPS connection; and
transmit server information corresponding to the eUICC information to the terminal,
wherein the information about the eUICC version comprises a minimum eUICC version and a maximum eUICC version that are available when the terminal accesses the server.

17. The server of claim 16 , wherein the processor is further configured to generate the server information comprising information about a server version corresponding to the maximum eUICC version, when the server supports both the minimum eUICC version and the maximum eUICC version or supports the maximum eUICC version.

18. The server of claim 17 , wherein the server information comprises a list of all or some of functions defined by a protocol of the server version.

19. The server of claim 18 , wherein the list is written by using a bitmap.

20. The server of claim 16 , wherein the processor is further configured to generate the server information not comprising information about a server version, when the server supports the minimum eUICC version.
