Abstract

The disclosure provides a method of processing communication service provider information by a terminal, the method including identifying a type of a secure element installed in the terminal; obtaining communication service provider information in the secure element through an application corresponding to the identified type of the secure element; and displaying the obtained communication service provider information.

First claim

The invention claimed is:

1. A method performed by a mobile terminal in a wireless communication system, the method comprising:
executing a plurality of applications respectively corresponding to types of a plurality of secure elements installed in the mobile terminal, wherein the plurality of secure elements comprise one of a subscriber identity module (SIM) card, an integrated smart secure platform (iSSP), a universal integrated circuit card (UICC), or an embedded UICC (eUICC);
obtaining, from the plurality of secure elements, information for a plurality of communication service providers associated with the plurality of secure elements, based on the executing of the plurality of applications;
displaying information for first communication service providers available in a first SIM slot corresponding to a first wireless technology or a first wireless technology combination, and information for second communication service providers available in a second SIM slot corresponding to a second wireless technology or a second wireless technology combination, among the plurality of communication service providers, based on the obtained information; and
in case that one of the first communication service providers is selected from user input, displaying information of at least one of one or more unselected first communication service providers as disabled and information of at least one of the second communication service providers as disabled, based on at least one policy information included in the obtained information, wherein information of the selected one of the first communication service providers is displayed as enabled.

2. The method of claim 1 , wherein the information for the plurality of communication service providers is obtained from the plurality of secure elements by controlling entities for accessing communication service provider information,
wherein the iSSP includes at least one of a SIM bundle or an embedded SIM (eSIM) bundle,
wherein the plurality of applications includes at least one of a card application toolkit (CAT) client corresponding to the UICC, a local profile agent (LPA) corresponding to the eUICC or a secondary platform bundle (SPB) loader agent corresponding to the iSSP, and
wherein the entities for accessing the communication service provider information include at least one of a CAT in the UICC, an issuer security domain root (ISD-R) in the eUICC or a SPB loader in the SIM bundle.

3. The method of claim 2 , wherein the obtaining of the information comprises, when a type of a secure element is identified as the UICC, obtaining communication service provider information stored in the UICC by controlling the CAT through the CAT client.

4. The method of claim 2 , wherein the obtaining of the information comprises, when a type of a secure element is identified as the eUICC, obtaining communication service provider information stored in the eUICC by controlling the ISD-R through the LPA.

5. The method of claim 2 , wherein the obtaining of the information comprises:
when a type of a secure element is identified as the iSSP, obtaining a telecom bundle class identifier in the iSSP through the SPB loader agent;
identifying a type of a bundle included in the iSSP, based on the obtained telecom bundle class identifier; and
when the iSSP includes the SIM bundle, obtaining communication service provider information stored in the SIM bundle by controlling the SPB loader through the SPB loader agent.

6. The method of claim 2 , wherein the obtaining of the information comprises:
when a type of a secure element is identified as the iSSP, obtaining a telecom bundle identifier in the iSSP through the SPB loader agent;
identifying a type of a bundle included in the iSSP, based on the obtained telecom bundle identifier; and
when the iSSP includes the eSIM bundle, obtaining communication service provider information provided in the eSIM bundle,
wherein the communication service provider information stored in the eSIM bundle is obtained, based on one among information in a metadata extension of the eSIM bundle and information cached in the mobile terminal, or by controlling a Local Profile Agent (LPA) corresponding to the eSIM bundle.

7. The method of claim 6 , wherein the obtaining of the communication service provider information stored in the eSIM bundle comprises:
identifying whether the eSIM bundle is disabled;
enabling the eSIM bundle, based on a result of the identifying; and
obtaining the communication service provider information stored in the eSIM bundle, based on the LPA corresponding to the eSIM bundle.

8. The method of claim 1 , wherein the at least one policy information includes:
first policy information of the plurality of secure elements or second policy information of a SIM bundle and an eSIM bundle,
wherein the displaying of the information for first communication service providers and the information for second communication service providers comprises:
displaying a plurality of first selection boxes respectively corresponding to the first communication service providers and a plurality of second selection boxes respectively corresponding to the second communication service providers,
wherein in case that a first selection box corresponding to the first communication service providers is selected, one or more selection boxes among the plurality of first selection boxes and the plurality of second selection boxes are displayed as disabled, based on the first policy information or the second policy information, and
wherein the one or more selection boxes displayed as disabled includes:
a second selection box corresponding to the first communication service provider;
one or more first selection boxes other than the selected first selection box;
in case that the first communication service provider corresponds to an eUICC, one or more second selection boxes associated with the eUICC; and
in case that the first communication service provider corresponds to the eSIM bundle, one or more second selection boxes associated with the eSIM bundle.

9. The method of claim 1 , further comprising:
accessing at least one of a communication service provider server or a market server;
selecting a communication service provider to connect, based on the accessing; and
determining a secure element for storing communication service provider information corresponding to the selected communication service provider.

10. The method of claim 9 , further comprising:
transmitting information associated with the secure element to the communication service provider server or the market server;
receiving address information corresponding to the communication service provider information to be downloaded from the communication service provider server or the market server, based on the information associated with the secure element; and
downloading the communication service provider information, based on the address information.

11. A mobile terminal in a wireless communication system, the mobile terminal comprising:
a transceiver; and
a processor coupled to the transceiver and configured to:
execute a plurality of applications respectively corresponding to types of a plurality of secure elements installed in the mobile terminal, wherein the plurality of secure elements comprise one of a subscriber identity module (SIM) card, an integrated smart secure platform (iSSP), a Universal Integrated Circuit Card (UICC), or an embedded UICC (eUICC);
obtain, from the plurality of secure elements, information for a plurality of communication service providers associated with the plurality of secure elements, based on the executing of the plurality of applications;
