Abstract

A method for downloading a profile of an electronic apparatus is provided. The method includes receiving profile information from a profile information transfer server, transmitting a profile request to an identified profile providing server based on the profile information, and receiving a profile installable in a universal integrated circuit card (UICC) of the electronic apparatus from the profile providing server, and an electronic apparatus. Further, the present disclosure may provide a profile information providing server providing the profile information to the electronic apparatus and an operation thereof, and a profile providing server providing a profile to the electronic apparatus and an operation thereof. Further, the present disclosure may provide a method for swapping a profile between apparatuses, a method for acquiring profile information using code information, a method for modifying a profile providing server, and an apparatus performing the same.

First claim

What is claimed is:

1. A method performed by an electronic apparatus in a communication system, the method comprising:
transmitting, to a subscription manager discovery service (SM-DS) server, a first message including information on an identifier for an embedded universal integrated circuit card (eUICC) of the electronic apparatus;
receiving, from the SM-DS server, a second message including information on an address for a subscription manager data preparation plus (SM-DP+) server and information on an identifier for an event;
transmitting, to the SM-DP+ server, a third message for requesting a profile based on the information on the address for the SM-DP+ server, wherein the third message includes the information on the identifier for the eUICC and the information on the identifier for the event, the event being associated with the profile;
receiving, from the SM-DP+ server, the profile; and
installing the profile in the eUICC of the electronic apparatus.

2. The method of claim 1 , wherein an address for the SM-DS server is preconfigured in the electronic apparatus.

3. The method of claim 1 , wherein the receiving of the profile comprises:
transmitting, to the SM-DP+ server, random information on the eUICC of the electronic apparatus;
receiving, from the SM-DP+ server, signature information associated with the random information and a certificate of the SM-DP+ server;
verifying the SM-DP+ server based on the signature information and the certificate;
transmitting, to the SM-DP+ server, encryption key generation data, in case that the verification succeeds; and
receiving, from the SM-DP+ server, the profile encrypted with an encryption key generated based on the encryption key generation data.

4. The method of claim 1 , wherein the address the identifier for the event is of a same type as a profile installation information.

5. An electronic apparatus in a communication system, the electronic apparatus comprising:
a transceiver; and
a processor configured to:
transmit, to a subscription manager discovery service (SM-DS) server via the transceiver, a first message including information on an identifier for an embedded universal integrated circuit card (eUICC) of the electronic apparatus,
receive, from the SM-DS server via the transceiver, a second message including information on an address for a subscription manager data preparation plus (SM-DP+) server and information on an identifier for an event,
transmit, to the SM-DP+ server via the transceiver, a third message for requesting a profile based on the information on the address for the SM-DP+ server, wherein the third message includes the information on the identifier for the eUICC and the information on the identifier for the event, the event being associated with the profile,
receive, from the SM-DP+ server via the transceiver, the profile, and
install the profile in the eUICC of the electronic apparatus.

6. The electronic apparatus of claim 5 , wherein an address for the SM-DS server is preconfigured in the electronic apparatus.

7. The electronic apparatus of claim 5 , wherein the processor is further configured to:
transmit, to the SM-DP+ server via the transceiver, random information on the eUICC of the electronic apparatus,
receive, from the SM-DP+ server via the transceiver, signature information associated with the random information and a certificate of the SM-DP+ server,
verify the SM-DP+ server based on the signature information and the certificate,
transmit, to the SM-DP+ server via the transceiver, encryption key generation data, in case that the verification succeeds, and
receive, from the SM-DP+ server via the transceiver, the profile encrypted with an encryption key generated based on the encryption key generation data.

8. A method performed by a subscription manager discovery service (SM-DS) server in a communication system, the method comprising:
receiving, from a subscription manager data preparation plus (SM-DP+) server, a first message including information on an identifier for an embedded universal integrated circuit card (eUICC) of an electronic apparatus, information on an address for the SM-DP+ server, and information on an identifier for an event;
receiving, from the electronic apparatus, a second message including the information on the identifier for the eUICC of the electronic apparatus; and
transmitting, to the electronic apparatus, a third message as a response to the second message, the third message including the information on the address for the SM-DP+ server and the information on the identifier for the event,
wherein the information on the address for the SM-DP+ server identifies the SM-DP+ server including a profile to be installed in the eUICC of the electronic apparatus, and
wherein the profile is associated with the identifier for the event.

9. The method of claim 8 , further comprising:
transmitting, to the SM-DP+ server, a fourth message as a response to the first message.

10. The method of claim 8 , further comprising:
storing the information on the identifier for the eUICC of the electronic apparatus, the information on the address for the SM-DP+ server, and the information on the identifier for the event.

11. A subscription manager discovery service (SM-DS) server in a communication system, the SM-DS server comprising:
a transceiver; and
a processor configured to:
receive, from a subscription manager data preparation plus (SM-DP+) server via the transceiver, a first message including information on an identifier for an embedded universal integrated circuit card (eUICC) of an electronic apparatus, information on an address for the SM-DP+ server, and information on an identifier for an event,
receive, from the electronic apparatus via the transceiver, a second message including the information on the identifier for the eUICC of the electronic apparatus, and
transmit, to the electronic apparatus via the transceiver, a third message as a response to the second message, the third message including the information on the address for the SM-DP+ server and the information on the identifier for the event,

wherein the information on the address for the SM-DP+ server identifies the SM-DP+ server including a profile to be installed in the eUICC of the electronic apparatus, and
wherein the profile is associated with the identifier for the event.

12. The SM-DS server of claim 11 , wherein the processor is further configured to transmit, to the SM-DP+ server via the transceiver, a fourth message as a response to the first message.

13. The SM-DS server of claim 11 , wherein the processor is further configured to store the information on the identifier for the eUICC of the electronic apparatus, the information on the address for the SM-DP+ server, and the information on the identifier for the event.
