Abstract

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The 5G or 6G communication system is directed to a method and an apparatus for installing a profile again when changing an embedded universal integrated circuit card (eUICC) terminal.

First claim

What is claimed is:

1 . A method performed by a subscription manager discovery service (SM-DS) in a wireless communication system for transferring a first embedded universal integrated circuit card (eUICC) profile of a first terminal to a second terminal, the method comprising:
receiving, from a subscription manager data preparation plus (SM-DP+), an event registration request message for an event related to a second eUICC profile to be installed in the second terminal, the event registration request message indicating that the event related to the second eUICC profile is not forwardable, and the second eUICC profile corresponding to the first eUICC profile installed in the first terminal; and transmitting, to the SM-DP+, an event registration response message in response to the event registration request message, the event registration response message comprising information indicating that the event related to the second eUICC profile is not forwardable to the second terminal, wherein the event related to the second eUICC profile is indicated as forwardable, based on identification of a deletion of the first eUICC profile from the first terminal.

2 . The method of claim 1 , wherein the event registration request message comprises at least one of:
an event identifier of the second eUICC profile prepared by the SM-DP+, and an event forwarding indicator indicating that the event is to be registered by the SM-DS as not forwardable.

3 . The method of claim 1 , further comprising:
receiving, from the SM-DP+, an event forwarding request message for requesting to configure the event as forwardable, in case that deletion of the first eUICC profile by the first terminal is identified by the SM-DP+; configuring the event as forwardable, based on the event forwarding request message; and transmitting, to the SM-DP+, an event forwarding response message for confirming the event being configured as forwardable.

4 . The method of claim 3 , further comprising:
transmitting, to the second terminal, a notification message notifying that the event related to the second eUICC profile has been registered in case that an activation code is transferred from the first terminal to the second terminal; receiving, from the second terminal, a message for requesting forwarding of the event; and transmitting, to the second terminal, an event list comprising information for downloading the second eUICC profile.

5 . A method performed by a subscription manager data preparation plus (SM-DP+) for providing an embedded universal integrated circuit card (eUICC) profile in a wireless communication system, the method comprising:
receiving, from a first terminal, a transfer request message for requesting transfer of a first eUICC profile installed in the first terminal to a second terminal, the transfer request message comprising at least one of an eUICC identifier installed in the second terminal, a type allocation code (TAC) of the second terminal, information on a subscription manager discovery service (SM-DS) supported by the second terminal, and an indicator indicating whether the SM-DS supported by the second terminal supports a push notification; preparing a second eUICC profile for transfer to the second terminal, the second eUICC profile corresponding to the first eUICC profile; transmitting, to the SM-DS, an event registration request message for an event related to the second eUICC profile to be installed in the second terminal, the event registration request message indicating that the event related to the second eUICC profile is not forwardable; and receiving, from the SM-DS, an event registration response message in response to the event registration request message, the event registration response message comprising information indicating that the event related to the second eUICC profile is not forwardable to the second terminal, wherein the event related to the second eUICC profile is indicated as forwardable, based on identification of a deletion of the first eUICC profile from the first terminal.

6 . The method of claim 5 , further comprising:
transmitting, to the first terminal, a transfer request result comprising information for downloading the second eUICC profile, the information for downloading the second eUICC profile comprising at least one of an activation code, a profile deletion indicator, and an event registration indicator, which correspond to the second eUICC profile; and receiving, from the first terminal, a notification confirming the deletion of the first eUICC profile.

7 . The method of claim 6 , further comprising:
transmitting, to the SM-DS, an event forwarding request message for requesting to configure the event as forwardable, in case that the deletion of the first eUICC profile is identified by the first terminal; receiving, from the SM-DS, an event forwarding response message for confirming the event being configured as forwardable; transmitting, to the first terminal, a first eUICC profile deletion verification result; receiving, from the second terminal, a download request message for downloading of the second eUICC profile; and transmitting, to the second terminal, the second eUICC profile.

8 . A subscription manager discovery service (SM-DS) in a wireless communication system for transferring a first embedded universal integrated circuit card (eUICC) profile of a first terminal to a second terminal, the SM-DS comprising:
a transceiver; memory, comprising one or more storage media, storing instructions; and at least one processor communicatively coupled to the transceiver and the memory, wherein the instructions, when executed by the one or more processors individually or collectively, cause the SM-DS to:
receive, from a subscription manager data preparation plus (SM-DP+) through the transceiver, an event registration request message for an event related to a second eUICC profile to be installed in the second terminal, the event registration request message indicating that the event related to the second eUICC profile is not forwardable, and the second eUICC profile corresponding to the first eUICC profile installed in the first terminal, and
transmit, to the SM-DP+ through the transceiver, an event registration response message in response to the event registration request message, the event registration response message comprising information indicating that the event related to the second eUICC profile is not forwardable to the second terminal, and
wherein the event related to the second eUICC profile is indicated as forwardable, based on identification of a deletion of the first eUICC profile from the first terminal.

9 . The SM-DS of claim 8 , wherein the event registration request message comprises at least one of:
an event identifier of the second eUICC profile prepared by the SM-DP+, and an event forwarding indicator indicating that the event is to be registered by the SM-DS as not forwardable.

10 . The SM-DS of claim 8 , wherein the instructions that, when executed by the at least one processor individually or collectively, further cause the SM-DS to:
receive, from the SM-DP+ through the transceiver, an event forwarding request message for requesting to configure the event as forwardable, in case that deletion of the first eUICC profile by the first terminal is identified by the SM-DP+, configure the event as forwardable, based on the event forwarding request message, and transmit, to the SM-DP+ through the transceiver, an event forwarding response message for confirming the event being configured as forwardable.

11 . The SM-DS of claim 10 , wherein the instructions that, when executed by the at least one proc
