Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). A terminal includes a transmission/reception unit, and at least one processor for controlling the terminal so as to receive a movement request of the profile from a user, confirm profile movement information, transmit, to a profile server, a message for requesting an activation code, receive the activation code and a profile deletion need from the profile server, delete the profile, transmit the deletion result of the profile to the profile server, transfer the activation code to another terminal, receive the activation code from another terminal, transmit a message for requesting the profile to the profile server by using the activation code, receive a profile package from the profile server, and install the profile package.

First claim

What is claimed is:

1. A method performed by a first terminal in a wireless communication system, comprising:
transmitting, to a server, a request message for a device change associated with a first profile in the first terminal; and
receiving, from the server, an activation code for the first profile and information notifying that a deletion of the first profile is required, in case that a new profile is not required for the device change; and
receiving, from the server, an activation code for a second profile, in case that the new profile is required for the device change.

2. The method of claim 1 , further comprising:
transmitting, to a second terminal, the activation code for the second profile.

3. The method of claim 1 , further comprising:
transmitting, to a second terminal, the activation code for the first profile;
deleting the first profile in the first terminal based on the information notifying that the deletion of the first profile is required; and
transmitting, to the server, a result of the deletion of the first profile.

4. A first terminal in a wireless communication system, the first terminal comprising:
a transceiver; and
a controller coupled to the transceiver and configured to:
transmit, to a server, a request message for a device change associated with a first profile in the first terminal, and
receive, from the server, an activation code for the first profile and information notifying that a deletion of the first profile is required, in case that a new profile is not required for the device change, and
receive, from the server, an activation code for a second profile, in case that the new profile is required for the device change.

5. The first terminal of claim 4 ,
wherein the controller is further configured to:
transmit, to a second terminal, the activation code for the second profile.

6. The first terminal of claim 4 ,
wherein the controller is further configured to:
transmit, to a second terminal, the activation code for the first profile,
delete the first profile in the first terminal based on the information notifying that the deletion of the first profile is required, and
transmit, to the server, a result of the deletion of the first profile.

7. The first terminal of claim 4 ,
wherein the controller is further configured to:
transmit, to the server, information on confirmation of user for the device change associated with the first profile in the first terminal.

8. The first terminal of claim 4 ,
wherein the activation code is provided in a QR code.

9. The method of claim 1 , further comprising:
transmitting, to the server, information on confirmation of user for the device change associated with the first profile in the first terminal.

10. The method of claim 1 ,
wherein the activation code is provided in a QR code.

11. A method performed by a server in a wireless communication system, the method comprising:
receiving, from a first terminal, a request message for a device change associated with a first profile in the first terminal;
in case that a new profile is not required for the device change, transmitting, to the first terminal, an activation code for the first profile and information notifying that a deletion of the first profile is required; and
in case that the new profile is required for the device change, transmitting, to the first terminal, an activation code for a second profile.

12. The method of claim 11 , further comprising:
receiving, from the first terminal, information on confirmation of user for the device change associated with the first profile in the first terminal.

13. A server in a wireless communication system, the server comprising:
a transceiver; and
a controller coupled to the transceiver and configured to:
receive, from a first terminal, a request message for a device change associated with a first profile in the first terminal,
in case that a new profile is not required for the device change, transmit, to the first terminal, an activation code for the first profile and information notifying that a deletion of the first profile is required, and
in case that the new profile is required for the device change, transmit, to the first terminal, an activation code for a second profile.

14. The server of claim 13 ,
wherein the controller is further configured to:
receive, from the first terminal, information on confirmation of user for the device change associated with the first profile in the first terminal.
