The communication module (190) may operate independently from the processor (120) (e.g., the application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module or a power line communication module). Among these communication modules, a corresponding communication module may communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) may use subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196) to identify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199).

The wireless communication module (192) can support a 5G network and next-generation communication technology after a 4G network, for example, NR access technology (new radio access technology).

In one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least part of the service. One or more external electronic devices that have received the request may execute at least a part of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may provide the result, as is or additionally processed, as at least a part of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

FIG. 1B is a diagram illustrating a network environment (100) including an electronic device according to one embodiment. Referring to FIG. 1B, a network (100) according to one embodiment of the present disclosure may include an electronic device (101), a first communication network (111a), and/or a second communication network (112a).

In one embodiment, an electronic device (101) (e.g., a user equipment (UE)) may access a wireless communication network in a wireless communication system to use a voice communication or data communication service at a fixed location or while moving. In order to provide a communication service to the electronic device (101), an appropriate authentication process may be required. For example, a UICC (universal integrated circuit card) may be inserted into the electronic device, and authentication may be performed between the electronic device (101) and a server of a mobile network operator (MNO) through a USIM (universal subscriber identity module) installed inside the UICC. In one embodiment, the UICC may be referred to as a SIM (subscriber identity module) card or a WCDMA (wideband code division multiple access) card in the case of a GSM (global system for mobile communications) scheme. The UICC may also be referred to as a USIM (universal subscriber identity module) card in the case of a LTE (long term evolution) scheme. In one embodiment, the USIM card or SIM card may be included in the electronic device (101) in the form of an independent UICC, and/or may be included within the electronic device (101) in an embedded form (e.g., embedded SIM, eSIM). The USIM card or SIM card may also be included within the electronic device (101) in a form integrated into at least one of the chips included in the electronic device (101) (e.g., integrated SIM, iSIM).

In one embodiment, when a user of an electronic device (101) subscribes to a wireless communication service provided by a telecommunications carrier, the telecommunications carrier may provide a UICC (e.g., a SIM card or a USIM card) to the user. The user may insert the provided UICC into his or her electronic device (101). In one embodiment, after the user of the electronic device (101) subscribes to a wireless communication service provided by the telecommunications carrier, the user may receive information to be stored in a UICC (e.g., an eSIM or iSIM) included in the electronic device (101) from the telecommunications carrier. In one embodiment, when the electronic device (101) receives information related to the UICC from the telecommunications carrier or when the UICC is inserted into the electronic device (101), the USIM application installed in the UICC may perform an authentication process. For example, based on an international mobile subscriber identity (IMSI) value and an encryption key value for authentication stored in the UICC, an appropriate authentication process may be performed between a server of the telecommunications carrier and the UICC where the same value is stored. The electronic device (101) can use a wireless communication service associated with the UICC after an appropriate authentication process is performed.

In one embodiment, the electronic device (101) may support two or more SIMs. An electronic device supporting two or more SIMs may be referred to as a dual SIM or multi-SIM electronic device. In one embodiment, the electronic device (101) being equipped with two or more SIM cards may mean that at least two independent UICCs are included in the electronic device (101). In one embodiment, the electronic device (101) being equipped with two or more SIM cards may mean that at least one rSIM (removable SIM) and at least one eSIM are included in the electronic device (101). In one embodiment, the electronic device (101) being equipped with two or more SIM cards may mean that at least one rSIM and at least one iSIM are included in the electronic device (101). In one embodiment, the presence of two or more SIM cards in the electronic device (101) may mean that an eSIM or iSIM supporting at least two networks is included in the electronic device (101). In one embodiment, the presence of two or more SIM cards in the electronic device (101) may mean that an eSIM supporting multiple profiles is included in the electronic device (101) instead of an rSIM. A dual SIM or multi-SIM electronic device may support multiple SIMs, each of which may be associated with a different subscription. In one embodiment, a mode in which one transceiver transmits and receives signals associated with multiple SIMs may be referred to as a dual SIM dual standby (DSDS) mode. For example, when a signal associated with one SIM is being transmitted and/or received, the other SIM may remain in standby mode. In one embodiment, a mode in which both SIMs can be activated simultaneously may be referred to as a dual SIM dual active (DSDA) mode.

In one embodiment, the electronic device (101) can operate as a DSDS (dual SIM dual standby) or DSDA (dual SIM dual active) electronic device supporting two SIMs in one device. The electronic device (101) can be equipped with at least one SIM card. For example, referring to FIG. 1B, the electronic device (101) can include a first SIM (111) and an eSIM (201). The first SIM (111) can be an rSIM. Hereinafter, for convenience of description, the SIM card will be referred to as a SIM.

In one embodiment, although not shown in FIG. 1B, those skilled in the art will readily understand that the electronic device (101) can accommodate two or more SIMs, and there is no limitation on the number or type of the SIMs. If the electronic device (101) accommodates two or more SIMs, the electronic device (101) may include multiple slots for accommodating multiple SIMs.

In one embodiment, the first SIM (111) may be a SIM subscribed to a telecommunications carrier of the first communication network (111a). The electronic device (101) may access the first communication network (111a) based on information stored in the first SIM (111). After accessing the first communication network (111a), the electronic device (101) may use a wireless communication service associated with the first SIM (111). In one embodiment, the electronic device (101) may include an embedded subscriber identity module (eSIM) (201). The eSIM may also be referred to as an embedded universal integrated circuit card (eUICC). The electronic device (101) may access the second communication network (112a) based on information stored in the eSIM (201). For example, the electronic device (101) may access the second communication network (112a) based on accessing at least one profile included in the eSIM (201). After accessing the second communication network (112a), the electronic device (101) may use a wireless communication service. In one embodiment, the first SIM (111) is illustrated as a SIM card in FIG. 1B for convenience of explanation, but the manner in which the first SIM (111) is implemented is not limited thereto. In one embodiment, the first SIM (111) may be an eSIM or an iSIM. For example, the first SIM (111) may also be implemented in the form of a profile included in the eSIM (201). In one embodiment, the eSIM (201) may include a plurality of profiles. The electronic device (101) can connect to the first communication network (111a) based on information stored in a first profile (not shown) among a plurality of profiles included in the eSIM (201). The electronic device (101) can connect to the second communication network (112a) based on information stored in a second profile (not shown) among a plurality of profiles included in the eSIM (201). In one embodiment, the first communication network (111a) and the second communication network (112a) may be provided by the same communication service provider, or may be provided by different communication service providers, respectively. In one embodiment, when the first communication network (111a) and the second communication network (112a) are provided by the same communication service provider, the first communication network (111a) and the second communication network (112a) may mean the same network. In one embodiment, different service providers may share a communication network. For example, a first communication service provider may utilize a first communication network (111a), and a second communication service provider may also be configured to utilize the first communication network (111a).

In one embodiment, a description that the LPA (210) (or a module included in the LPA (210)) performs a particular operation may mean that the processor (120) performs the particular operation based on executing the LPA (210). In one embodiment, the LPA (210) may include a plurality of modules that perform particular operations within the electronic device (101). For example, the LPA (210) may include local discovery services (LDS) (211), a local profile download (LPD) (213), and a local user interface (LUI) (215).

In one embodiment, the LDS (211) may perform operations such as communicating with a subscription manager discovery service (SM-DS) server and/or receiving an address of a subscription manager data preparation plus (SM-DP+) server from which an operational profile can be downloaded from the SM-DS server based on a provisioning profile.

In one embodiment, the LPD (213) may perform an operation of establishing a connection with an SM-DP+ server through a wireless communication network based on an address of the SM-DP+ server and receiving an operational profile from the SM-DP+ server. In one embodiment, the LPD (213) may support a profile download, enable, disable, delete, or profile policy rule (PPR) download operation initiated by the network, or may support a profile enable, disable, delete, or eUICC reset operation performed by the electronic device (101).

In one embodiment, the LUI (215) may perform an operation that provides at least one user interface when downloading an operational profile. In one embodiment, the LUI (215) may support data exchange between a user and the LDS (211) and/or the LPD (213). The LUI (215) may include at least one user interface that conveys user input to the LDS (211) and/or the LPD (213).

In one embodiment, the processor (120) may perform data exchange with the eSIM (201) based on executing the LPA (210). For example, the processor (120) may transmit a command to the eSIM (201) based on executing the LPA (210). In response to the command, the processor (120) may obtain information associated with at least one of a plurality of profiles included in the eSIM (201) from the eSIM (201). In one embodiment, the processor (120) may perform a communication service based on information stored in the eSIM (201) by using (or executing) the LPA (210). For example, an electronic device (e.g., processor (120)) can perform a communication connection with an SM-DP+ server through a communication module (190) based on a provisioning profile stored in an eSIM (201) by using LPA (210). The processor (120) can download a profile (e.g., operational profile) including subscriber identification information from the SM-DP+ server.

According to one embodiment, the eSIM (201) (e.g., the subscriber identification module (196) of FIG. 1A and/or the eSIM (201) of FIG. 1B) may include one or more profiles as information for receiving a communication service. The profile may mean at least one of an application, a file system, or an authentication key value stored in the memory (203) of the eSIM (201) packaged in software form. For example, the profile may include a provisioning profile and an operational profile. The operational profile may include subscriber identification information. In one embodiment, the operational profile may further include information related to the subscriber's network access authentication information, the subscriber's phone book, the subscriber's personal information (e.g., SMS), the name of the telecommunications service provider to which the subscriber is subscribed, available services, available data volume, rates, or service provision speeds. The operational profile may further include information that enables secure wireless communication usage by performing subscriber authentication and traffic security key generation when connecting to a wireless communication network (e.g., a GSM, WCDMA, LTE, or 5G network). In one embodiment, the operational profile may include a SIM profile. For example, the SIM profile may include a SIM file system (e.g., a master file (MF), a dedicated file (DF), and/or elementary files (EF). The elementary files may store subscriber identity information (IMSI) values.

In one embodiment, the provisioning profile may be a profile that includes information associated with the download of the operational profile. For example, the provisioning profile may include communication session information designated for the download of the operational profile. The communication session information may include connection information to the SM-DS server and/or network information of a communication service provider available for connection to the SM-DS server.

In one embodiment, the communication module (190) (e.g., the communication module (190) of FIG. 1A) can perform a first communication based on a provisioning profile and/or a second communication based on an operational profile. In one embodiment, the display module (160) can display at least one execution screen associated with the first communication based on the provisioning profile and/or the second communication based on the operational profile.

In one embodiment, the LPA (210) is described as a configuration included in the processor (120) in FIG. 2, but is not limited thereto. For example, the LPA (210) may be included in a program (e.g., the program (140) of FIG. 1A) and may be loaded and executed on the processor (120). In one embodiment, the description that the LPA (210) performs a specific operation may be understood as an operation of the processor (120) when the LPA (210) is loaded and executed on the processor (120). In one embodiment, the function modules included in the LPA (210) (e.g., the LDS (211), the LPD (213), and/or the LUI (215)) are exemplarily separated, and those skilled in the art will understand that the function modules may be expressed as other function modules. In one embodiment, the LPA (210) may also be included in the eSIM (201).

FIG. 3 is a block diagram showing the configuration of an electronic device according to one embodiment.

According to one embodiment, the electronic device (101) may include at least one of a processor (120), a communication processor (310) (e.g., a coprocessor (123) of FIG. 1 , a wireless communication module (192)), an RF circuit (320) (e.g., a wireless communication module (192) of FIG. 1 ), a memory (130), a first slot (301), and/or an eSIM (201).

In one embodiment, the communication processor (310) may support establishment of a communication channel of a band to be used for wireless communication, and network communication through the established communication channel. For example, the communication processor (310) may support at least one of second generation (2G), 3G, LTE, or 5G network communication. In one embodiment, the processor (120) and/or the communication processor (310) may be electrically and/or operatively connected to the eSIM (201). In one embodiment, the communication processor (310) may perform an operation associated with at least one of a plurality of profiles included in the eSIM (201) based on exchanging data with the eSIM (201). For example, the communication processor (310) may generate a command including identification information of a port corresponding to the at least one profile based on receiving a control signal from the processor (120). The communication processor (310) may perform an operation associated with at least one profile based on transmitting the generated command to the eSIM (201). For example, the communication processor (310) may select one of a plurality of profiles included in the eSIM (201) and perform network communication corresponding to the selected profile. In one embodiment, in the embodiment of FIG. 3, the processor (120) and the communication processor (310) are illustrated as being different hardware, but this is merely exemplary, and the processor (120) and the communication processor (310) may be implemented in a single chip.

In one embodiment, the communication processor (310) may perform an authentication operation based on information stored in the first SIM (111) (e.g., the first SIM (111) of FIG. 1b ) and/or the eSIM (201) (e.g., the subscriber identity module (196) of FIG. 1a , the eSIM (201) of FIG. 1b , and/or the eSIM (201) of FIG. 2 ). In one embodiment, the communication processor (310) may be electrically and/or operatively connected to the first SIM (531) via the first slot (301). For example, the first SIM (111) may be connected to a protocol stack of the communication processor (310) (e.g., a protocol stack according to ISO-7816). In one embodiment, the communication processor (310) may include one or more protocol stacks. For example, the communication processor (310) may include two protocol stacks. In one embodiment, the first slot (301) may be a structure capable of accommodating a first SIM (111), which is an rSIM, and may include at least one terminal for transmitting information stored in the first SIM (111) to the communication processor (310). Those skilled in the art will readily appreciate that, in one embodiment, the electronic device (101) may further include a second slot (not shown) for accommodating another rSIM (e.g., a second SIM (not shown)). In one embodiment, the communication processor (310) may obtain information for accessing a communication network (e.g., the first communication network (111a) and/or the second communication network (112a)) from the eSIM (201) and/or the first SIM (111) accommodated in the first slot (301). For example, the first SIM (111) and/or the eSIM (201) may store at least one of an integrated circuit card identifier (ICCID), an IMSI, home public land mobile network (HPLMN) related information, or a mobile subscriber international ISDN number (MSISIDN). The information stored in the first SIM (111) and/or the eSIM (201) may also be referred to as a basic file. The communication processor (310) may perform an authentication operation for network communication through the RF circuit (320) based on the information obtained from the first SIM (111) and/or the eSIM (201). If the authentication is successful, the communication processor (310) may perform network communication through the RF circuit (320). In one embodiment, although the electronic device (101) is illustrated in FIG. 3 as including both a first slot (301) and an eSIM (201), those skilled in the art will readily appreciate that the electronic device (101) may not include a first slot (301) and a first SIM (111) accommodated in the first slot (301). For example, the electronic device (101) may include only an eSIM (201) that supports multiple profiles.

In one embodiment, the memory (130) may be included in the memory (130) (or non-volatile memory (134)) of FIG. 1A. The memory (130) may store instructions. The instructions, when executed by the processor (120), may cause the electronic device (101) to perform at least one operation. The at least one operation may include, for example, an overall operation associated with a profile stored in the eSIM (201).

In one embodiment, the RF circuit (320) may include at least one of, for example, a radio frequency integrated circuit (RFIC), a radio frequency front end (RFFE), or an antenna module (e.g., the antenna module (197) of FIG. 1A). The RF circuit (320) may radiate an RF signal through the antenna module based on processing data (e.g., a baseband signal) output from the communication processor (310). The RF circuit (320) may convert an RF signal received through the antenna module into a baseband signal and transmit the converted signal to the communication processor (310). The RF circuit (320) may process an RF signal or a baseband signal depending on a communication method supported by the communication processor (310), and there is no limitation on the type of the RF circuit (320). In one embodiment, the interface between the communication processor (310) and the RF circuit (320) may be implemented as, for example, a general purpose input/output (GPIO), a universal asynchronous receiver/transmitter (UART) (e.g., a high speed-UART (HS-UART)), and/or a peripheral component interconnect bus express (PCIe) interface, and there is no limitation on the type of the interface. In one embodiment, at least a portion of the communication processor (310) and the RF circuit (320) may exchange control information or packet data information, for example, by using the memory (130) (e.g., the memory (130) of FIG. 1A or a shared memory).

FIG. 4 is a block diagram illustrating the structure of an eSIM according to one embodiment.

An eSIM (201) according to one embodiment (e.g., subscriber identity module (196) of FIG. 1A, eSIM (201) of FIG. 1B, eSIM (201) of FIG. 2, and/or eSIM (201) of FIG. 3) may be implemented in the form of a card or a chip. In one embodiment, one or more profiles in software format (e.g., a first profile (401) and a second profile (403)) may be installed in the eSIM (201). The eSIM (201) may also be referred to as an eUICC. Although the eSIM (201) is illustrated in FIG. 4 as including two profiles, this is not a limitation, and the eSIM (201) may include one or more profiles. In one embodiment, each of the one or more profiles may be a provisioning profile or an operational profile. The first profile (401) and/or the second profile (403) can operate on an eUICC operating system (OS) (420). In one embodiment, the first profile (401) and/or the second profile (403) can be enabled or disabled by a processor (e.g., the processor (120) of FIG. 1A, the processor (120) of FIG. 2, the processor (120) of FIG. 3, and/or the communication processor (310)) or an LPA (e.g., the LPA (210) of FIG. 2). In one embodiment, the first profile (401) and the second profile (403) can be enabled based on a multiple enabled profiles (MEPs) function.

An issuer security domain root (ISD-R) (410) according to one embodiment can manage each of one or more profiles installed in the eSIM (201). For example, the ISD-R (410) can manage the profiles installed in the eSIM (201) based on exchanging data with a processor or LPA through an interface (e.g., an interface according to ISO-7816).

An eUICC OS (420) according to one embodiment may manage policy rules (PPR) for each of one or more profiles, unpackage a profile package received from a server (e.g., an SM-DP+ server), and/or perform functions associated with communication of the eSIM (201).

FIG. 5 is a block diagram showing the configuration of an electronic device according to one embodiment.

According to one embodiment, the electronic device (101) may include at least one of the processor (120), the communication processor (310), and/or the eSIM (201). In one embodiment, the electronic device (101) may execute a first protocol stack (511) and a second protocol stack (513) to support dual SIM. In one embodiment, for convenience of explanation, the first protocol stack (511) and the second protocol stack (513) are illustrated as being separated in FIG. 5 , and at least a portion of the first protocol stack (511) and the second protocol stack (513) may be configured with the same instructions, or may be separated into one or more protocol stacks, respectively. In one embodiment, when the electronic device (101) is capable of executing three or more protocol stacks at the same time, for example, the electronic device (101) may be implemented as an "electronic device supporting a triple SIM function" or an "electronic device supporting a quadruple SIM function."

In one embodiment, the processor (120) (e.g., the processor (120) of FIG. 1A , the processor (120) of FIG. 2 , the processor (120) of FIG. 3 , and/or the application processor) may include an LPA (210) (e.g., the LPA (210) of FIG. 2 ). In one embodiment, the LPA (210) may exchange data with the communication processor (310) to support download, installation, and/or management operations associated with a profile of the eSIM (201). In one embodiment, a description that the LPA (210) (or a module included in the LPA (210)) performs a particular action may mean that the processor (120) performs the particular action based on executing the LPA (210). In one embodiment, the processor (120) may also perform the functions of a SIM card manager.

A communication processor (310) according to one embodiment (e.g., the communication processor (310) of FIG. 3) may associate a first protocol stack (511) and/or a second protocol stack (513) with an eSIM (201). In one embodiment, the first protocol stack (511) and the second protocol stack (513) may be logically implemented within the communication processor (310). For example, the communication processor (310) may associate the eSIM (201) with one of the protocol stacks (511, 513) of the electronic device (101) by mapping a specific port number (or a specific slot number) to the eSIM (201). In one embodiment, the communication processor (310) and the eSIM (210) may be connected via a single physical pin (or a hardware circuit line). In one embodiment, the communication processor (310) may access at least one activated profile among the plurality of profiles based on a virtual interface (or identifier) corresponding to the plurality of profiles included in the eSIM (210). For example, one physical interface may be divided into a plurality of virtual interfaces (or logical interfaces) through multiplexing. In one embodiment, each of the plurality of virtual interfaces may be referred to as a “port,” and each port may be distinguished by a port ID (or port number). The communication processor (310) may access a profile mapped to the port ID based on transmitting an APDU command including the port ID to the eSIM (201). In one embodiment, referring to FIG. 5, the first profile (401) may be mapped to the first port (501) or the second port (503) when the first profile (401) is activated. The second profile (403) may be mapped to the second port (503) or the first port (501) when the second profile (403) is activated. For example, when the first profile (401) is mapped to the first port (501), the second profile (403) may be mapped to the second port (503). When the first profile (401) is mapped to the second port (503), the second profile (403) may also be mapped to the first port (501). In one embodiment, the communication processor (310) may access the first profile (401) and/or the second profile (403) installed in the eSIM (201) through the first port (501) (or, eSIM port 1). For example, the communication processor (310) can access the first profile (401) through the first port (501) if the first profile (401) is mapped to the first port (501). The communication processor (310) can access the second profile (403) through the first port (501) if the second profile (403) is mapped to the first port (501). The communication processor (310) can also access the first profile (401) and/or the second profile (403) installed in the eSIM (201) through the second port (503) (or, eSIM port 2). For example, the communication processor (310) can access the first profile (401) through the second port (503) if the first profile (401) is mapped to the second port (503). The communication processor (310) can access the second profile (403) via the second port (503) when the second profile (403) is mapped to the second port (503). In one embodiment, not shown in FIG. 5, the ISD-R (e.g., the ISD-R (410) of FIG. 4) can communicate with the communication processor (310) and/or the processor (120) (or the LPA (210)) via the first port (501) and the second port (503) and an independent eSIM port (not shown). For example, the ISD-R (410) can communicate with the communication processor (310) via port #0 (or eSIM port 0) in MEP-A (e.g., MEP-A1 or MEP-A2) mode. In one embodiment, port #0 may be a port that is distinct from the first port (501) and the second port (503) among the plurality of ports (or virtual interfaces). The ISD-R (410) may communicate with the communication processor (310) through any one of the plurality of ports in the MEP-B mode. The port assigned to the IDS-R (410) in the MEP-B mode may be the first port (501) or the second port (503). The port assigned to the IDS-R (410) in the MEP-B mode may also be a port that is distinct from the first port (501) and the second port (503) among the plurality of ports.

In one embodiment, the communication processor (310) may exchange data with the eSIM (201) via a single physical interface according to ISO-7816. For example, the communication processor (310) may be connected to the eSIM (201) via a single physical pin (or physical channel). In one embodiment, the communication processor (310) and the eSIM (201) may support MEPs functionality to perform operations associated with a plurality of activated profiles via a plurality of virtual interfaces (or logical interfaces or ports). In one embodiment, the communication processor (310) may perform operations associated with a plurality of profiles installed in the eSIM (201) based on the MEPs functionality. For example, the communication processor (310) may perform operations associated with at least one of the plurality of activated profiles based on transmitting a command to the eSIM (201).

In one embodiment, the communication processor (310) may exchange data with the eSIM (201) based on a set protocol. The communication processor (310) may transmit an APDU (application protocol data unit) command to the eSIM (201) through an interface. The eSIM (201) may transmit a result value to the communication processor (310) in response to the APDU command. For example, the communication processor (310) may exchange data with the eSIM (201) based on the T=0 protocol according to ISO 7816-3. In one embodiment, the T=0 protocol may be a protocol associated with a command in a character-based format. In one embodiment, the communication processor (310) may also exchange data with the eSIM (201) based on the T=1 protocol. In one embodiment, the T=1 protocol may utilize a method of exchanging data in block units. For example, the communication processor (310) can transmit a command having a block unit size to the eSIM (201). The command transmitted to the eSIM (201) may be in the form of an APDU. In one embodiment, the communication processor (310) can communicate with the eSIM (201) by transmitting and receiving a small amount of data based on the T=0 protocol compared to the T=1 protocol. Hereinafter, it is assumed that the communication processor (310) exchanges data with the eSIM (201) based on the T=0 protocol. In one embodiment, the electronic device (101) can perform operations associated with a plurality of activated profiles (for example, a first profile (401) and a second profile (403)) through a plurality of logical channels formed between the communication processor (310) and the eSIM (201). In one embodiment, the communication processor (310) may perform an operation associated with one of the plurality of profiles by transmitting an APDU command to the eSIM (201) when exchanging data with the eSIM (201) based on the T=0 protocol. For example, the communication processor (310) may distinguish a logical channel for the first profile (401) from a logical channel for the second profile (403) based on transmitting a MANAGE LSI (logical secure element interface) to the eSIM (201).

FIG. 6 illustrates a flowchart (600) of a method of operating an electronic device according to one embodiment.

In one embodiment, the electronic device (101) (e.g., the processor (120) and/or the communication processor (310)) may, in operation 601, reset an eUICC (e.g., an eSIM (201)). In one embodiment, the electronic device (101) may exchange data with the eUICC based on a first protocol associated with a character-based format command. For example, the electronic device (101) may communicate with the eUICC based on a T=0 protocol. The electronic device (101) may transmit a reset signal to the eUICC as at least part of an initialization process of the eUICC.

In one embodiment, the electronic device (101) may, in operation 603, determine whether the eUICC supports a first function associated with identification of a port corresponding to at least one of the plurality of profiles. In one embodiment, the electronic device (101) may determine whether the eUICC supports the first function associated with identification of a port corresponding to at least one of the plurality of profiles, based on verifying an ATR obtained from the eUICC or obtaining a response from the eUICC in response to the MANAGE LSI. In one embodiment, the description that the eUICC supports the first function may mean that the eUICC supports a format of an APDU command transmitted by the electronic device (101).

In one embodiment, the electronic device (101) can check an ATR (answer to reset) transmitted by the eUICC in response to a reset signal. Based on the checking of the ATR, the electronic device (101) can check that the eUICC supports eUICC-related functions and a first interface (e.g., logical secure element interfaces (LSIs)). In one embodiment, the electronic device (101) can check, for example, a TB ₃ field of the ATR based on the checking that the eUICC supports the eUICC-related functions and the first interface. Based on the checking of the bit information of the TB ₃ field of the ATR, the electronic device (101) can check whether a maximum number of a plurality of logical channels formed between a communication processor (e.g., the communication processor 310) and an eSIM (e.g., the eSIM (201)) is greater than or equal to a first value. For example, the electronic device (101) can determine that the maximum number of the plurality of logical channels is 8 or more based on determining that the values of x, y, and z of the third sw function table are 1. The field that the electronic device (101) refers to to determine the maximum number of logical channels and the first value corresponding to the criterion of the maximum number are not limited to the above-described example.

In one embodiment, the electronic device (101) may transmit a command associated with the first interface to the eUICC based on obtaining an ATR from the eUICC. For example, the electronic device (101) may determine that the eUICC supports LSIs based on verifying the ATR obtained from the eUICC. The electronic device (101) may transmit a command (e.g., MANAGE LSI) to the eUICC based on verifying that the eUICC supports LSIs. In one embodiment, a field associated with a MEP mode of the MANAGE LSI may include information associated with port mapping. For example, if the electronic device (101) supports MEP-A1, the field associated with the MEP mode may include command data corresponding to '11'. If the electronic device (101) supports MEP-A2, the field associated with the MEP mode may include command data corresponding to '12'. When the electronic device (101) supports MEP-B, the field associated with the MEP mode may include command data corresponding to '13'. In one embodiment, the field used by the electronic device (101) to transmit information associated with port mapping to the eUICC and the specific command data included in the field are not limited to the examples described above. The electronic device (101) may confirm that the eUICC supports the first function based on obtaining a response from the eUICC in response to the MANAGE LSI (configure LSI).

In one embodiment, the electronic device (101) may activate the plurality of profiles in operation 605 based on determining (operation 603-Yes) that the eUICC supports a first function associated with identification of a port corresponding to at least one of the plurality of profiles.

In one embodiment, the electronic device (101) can determine that the eUICC supports the first function based on the ATR. The electronic device (101) can determine that the eUICC supports the first function based on checking the 3 ^rd sw function table of the global interface byte. The electronic device (101) can determine that the eUICC supports the first function based on checking that the maximum number of multiple logical channels is 8 or more, for example. In one embodiment, the electronic device (101) can also determine that the eUICC supports the first function based on obtaining a response to MANAGE LSI from the eUICC. In one embodiment, the electronic device (101) can activate the first profile (e.g., the first profile (401)) and the second profile (e.g., the second profile (403)) through the ISD-R of the eUICC (e.g., the ISD-R (410)).

In one embodiment, the electronic device (101) may perform an operation associated with the first profile based on activating a plurality of profiles, in operation 607, transmitting first data including identification information of a first port corresponding to the first profile to the eUICC.

In one embodiment, the electronic device (101) may transmit an APDU command including identification information of the first port to the eUICC. The electronic device (101) may transmit the identification information of the first port to the eUICC through a header of the APDU command. In one embodiment, the APDU command may be generated based on ISO 7816-4. For example, the identification information of the first port may be included in the b4 bit of the class field.

In one embodiment, the electronic device (101) may transmit identification information of a first port corresponding to a first index of one or more channels set based on the b4 bit, the b3 bit, the b2 bit, and the b1 bit of the class field to the eUICC. For example, odd channels may be mapped to the first port (e.g., the first port (501)), and even channels may be mapped to the second port (e.g., the second port (503)). For example, the 0th to 9th channels may be mapped to the first port, and the 10th to 19th channels may be mapped to the second port.

In one embodiment, the electronic device (101) can activate the multiple profiles in operation 609 based on determining that the eUICC does not support a first function associated with the identification of a port corresponding to at least one of the multiple profiles (operation 603-No). In one embodiment, the electronic device (101) can activate a first profile (e.g., the first profile (401)) and a second profile (e.g., the second profile (403)) via the ISD-R of the eUICC (e.g., the ISD-R (410)).

In one embodiment, the electronic device (101) can perform an operation associated with the first profile based on, in operation 611, transmitting a command associated with selection of a first port corresponding to the first profile to the eUICC based on activating a plurality of profiles. In one embodiment, the electronic device (101) can change a profile to be accessed based on transmitting a command (SELECT) associated with selection of a profile and receiving a response thereto from the eUICC.
