Description

Electronic devices and how to select a SIM using them

[0001] Embodiments of the present disclosure relate to an electronic device and a SIM selection method using the same.

[0002] With the recent advancement of digital technology, various types of electronic devices (user devices) capable of communication and personal information processing (e.g., mobile terminals, PDAs (Personal Digital Assistants), electronic organizers, smartphones, tablets, PCs (Personal Computers), etc.) are being released. As the functions provided by electronic devices diversify and their widespread use in daily life increases, the amount of time spent using them is gradually increasing. Electronic devices can be designed to be easily portable, with a certain size and weight, and may have constraints on the arrangement of their components.

[0003] A subscriber identity module (SIM, SIM card) is an IC card that stores subscriber information for an electronic device (or user terminal) used for wireless network communication. For example, a subscriber identity module can store various information used to authenticate a user's usage rights. An electronic device can communicate with a wireless network using a single SIM (e.g., a single SIM), but may also include two or more SIMs (e.g., multiple SIMs), in which case the subscriber information for each SIM can be used to access each wireless network.

[0004] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

[0005] An electronic device with multiple SIMs can select one of the SIMs and perform user authentication based on the selected SIM. For example, an electronic device with multiple SIMs can select one of the SIMs using a switching component (e.g., an analog switch). If a conflict occurs between the communication signals corresponding to each SIM during the selection process, network access may be interrupted.

[0006] According to one embodiment, an electronic device may provide a method for selecting a SIM without causing a collision between communication signals. The electronic device may include a signal application module (e.g., a chip select) for selecting a SIM among a plurality of SIMs, and may provide a method for activating a SIM among the plurality of SIMs using the signal application module. The electronic device may supply power to the selected SIM while cutting off power to other SIMs that are not selected.

[0007] The technical tasks to be achieved in this document are not limited to the technical tasks mentioned above, and other technical tasks not mentioned will be clearly understood by those with ordinary skill in the technical field to which this document pertains from the description below.

[0008] According to one embodiment, an electronic device may include a slot for inserting a card storing a first SIM, a security circuit storing a second SIM, a processor including a processing circuit, a level shifter connected to a signal path electrically connecting the processor and the slot, a first signal application module electrically connected to the level shifter and controlling signal transmission between the processor and the first SIM based on the level shifter, a second signal application module connected to a signal path electrically connecting the processor and the security circuit and controlling signal transmission between the processor and the second SIM, a power module supplying power to the first SIM and the second SIM, and a memory storing instructions. When the instructions are individually or collectively executed by the processor, the electronic device may be configured to, in response to selection of the first SIM, transmit a first signal (e.g., a High signal) to the first SIM through the level shifter under the control of the first signal application module, and supply power to the selected first SIM based on the power module, and in response to selection of the first SIM, transmit a second signal (e.g., a Low signal) different from the first signal to the second SIM through the second signal application module, and cut off power to the second SIM based on the power module.

[0009] According to one embodiment, a SIM selection method may include, in response to selection of a first SIM stored in a card inserted through a slot, an operation of transmitting a first signal to the first SIM through a level shifter electrically connected to the first SIM under the control of a first signal application module that controls signal transmission to the first SIM (301); an operation of supplying power to the selected first SIM based on a power module of the electronic device; an operation of transmitting a second signal, different from the first signal, to the second SIM through a second signal application module that controls signal transmission to the second SIM stored in a security circuit in response to selection of the first SIM; and an operation of cutting off power to the second SIM based on the power module.

[0010] According to one embodiment, a non-transitory computer-readable storage medium (or, a computer program product) storing one or more programs for performing a method for selecting a SIM in an electronic device may be described. According to one embodiment, the one or more programs may include instructions that, when executed by a processor of the electronic device, perform the following operations: in response to selection of a first SIM stored in a card inserted through a slot, transmitting a first signal to the first SIM through a level shifter electrically connected to the first SIM under the control of a first signal application module controlling signal transmission to the first SIM; supplying power to the selected first SIM based on a power module of the electronic device; in response to selection of the first SIM, transmitting a second signal, different from the first signal, to the second SIM through a second signal application module controlling signal transmission to the second SIM stored in a security circuit; and based on the power module, cutting off power to the second SIM.

[0011] According to one embodiment, an electronic device is a device that supports multiple SIMs (e.g., physical SIMs (pSIMs), embedded SIMs (eSIMs)) and may include a signal application module (e.g., chip select) for selecting one SIM among the multiple SIMs. The electronic device may include a signal application module directly or indirectly connected to each SIM. For example, when establishing a communication connection using a first SIM, the electronic device may activate the first SIM based on the first signal application module.

[0012] In one embodiment, the electronic device may supply power to a selected SIM based on the power module. For example, the electronic device may supply power to a selected SIM based on the power module and cut off power to the remaining SIMs, but not to the selected SIM.

[0013] According to one embodiment, an electronic device may provide a method for activating only a selected SIM to prevent signal collisions due to a communication connection when selecting a SIM for communication connection. The electronic device may transmit a signal to the selected SIM to activate the selected SIM based on a signal application module, and may supply power to the selected SIM based on a power module. The electronic device may prevent collisions between communication signals when performing communication based on the selected SIM. Since the electronic device utilizes the signal application module rather than a switch (e.g., an analog switch) to select a SIM among a plurality of SIMs, the switch may be eliminated from internal components. According to one embodiment, by eliminating the switch from the electronic device, the design cost of the electronic device may be reduced, and an internal space equivalent to the space occupied by the switch may be secured. Space utilization may be improved when designing the electronic device.

[0014] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure pertains from the description below.

The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0026] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state.

[0045] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to 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 a part of the service.

The electronic device (101) of FIG. 3 may refer to a state in which the first SIM (301) is inserted through the slot, and the second SIM (302) is stored based on the security circuit. According to one embodiment, when the first SIM (301) is selected while the SIM card including the first SIM (301) is inserted into the slot of the electronic device (101), the first SIM (301) may be activated. According to one embodiment, when the second SIM (302) is selected while the second SIM (302) is stored in the security circuit of the electronic device (101), the second SIM (302) can be activated.

[0056] According to one embodiment, the processor (120) may select the first SIM (301) through the level shifter (311) based on the first signal application module (321). For example, the level shifter (311) may be electrically connected on a signal path along which the processor (120) and a slot (e.g., the first SIM (301)) are electrically connected. The first signal application module (321) may be electrically connected to the level shifter (311) and, based on the level shifter (311), may control signal transmission between the processor (120) and the first SIM. The first signal application module (321) may control a communication connection (e.g., signal transmission) by the first SIM (301). The processor (120) may select the second SIM (302) using the second signal application module (322). For example, the second signal application module (322) may be electrically connected to a signal path along which the processor (120) and the security circuit (e.g., the second SIM (302)) are electrically connected. The second signal application module (322) may be directly connected to the second SIM (302) and may control a communication connection (e.g., signal transmission) by the second SIM (302).

[0057] According to one embodiment, the processor (120) of the electronic device (101) may execute a program stored in the memory (130) (e.g., the program (140) of FIG. 1, an application that provides a function of selecting one SIM from among a plurality of SIMs) to control at least one other component (e.g., a hardware or software component) and perform various data processing or calculations. For example, the processor (120) may select one SIM from among a plurality of SIMs (e.g., the first SIM (301) and / or the second SIM (302)) and perform a communication connection based on the selected one SIM. For example, in response to the selection of the first SIM (301), the processor (120) may perform a communication connection based on the first SIM (301). In another example, in response to the selection of the second SIM (302), the processor (120) may perform a communication connection based on the second SIM (302). According to one embodiment, the processor (120) may be operatively, functionally and / or electrically connected to a memory (130), a communication module (190), a power module (330), a SIM control module (340) for selecting a first SIM (301) and / or a second signal application module (322) for selecting a second SIM (302).

[0059] According to one embodiment, the memory (130) of the electronic device (101) may store information related to a signal transmitted to the SIM when selecting a SIM. For example, when the first SIM (301) is selected, the processor (120) may apply a first signal set to the level shifter (311) based on the first signal application module (321). The memory (130) may store information related to the set first signal. For another example, when the second SIM (302) is selected, the processor (120) may apply a second signal set to the second signal application module (322). The memory (130) may store information related to the set second signal. According to one embodiment, each of the signal application modules (321, 322) may include one chip select. For example, the first signal application module (321) can control a signal supplied to the first SIM (301) through the level shifter (311) and determine whether to select the first SIM (301). The first signal application module (321) can perform an operation of allowing a connection between the processor (120) and the first SIM (301) or blocking the connection. For example, the processor (120) can transmit a first signal (e.g., a high signal) to the first SIM (301) through the level shifter (311) and activate the first SIM (301). The processor (120) can transmit a second signal (e.g., a low signal) to the first SIM (301) through the level shifter (311) and deactivate the first SIM (301).

[0060] According to one embodiment, the processor (120) may be operatively or functionally connected to an external electronic device through the communication module (190). For example, when a first SIM (301) is selected from among a plurality of SIMs, the processor (120) may perform a communication connection based on the first SIM (301). The processor (120) may control a signal supplied to the first SIM (301) through the level shifter (311) based on the first signal application module (321). For example, the signal supplied to the first SIM (301) from the level shifter (311) may be determined as one of a high signal and / or a low signal. For example, when selecting the first SIM (301), the processor (120) can control the first signal application module (321) to transmit a high signal to the first SIM (301) through the level shifter (311), and select the first SIM (301). The processor (120) and the first SIM (301) are electrically connected, and the level shifter (311) can be electrically connected on a signal path between the processor (120) and the first SIM (301). The electronic device (101) can control a signal transmitted to the first SIM (301) based on the level shifter (311) under the control of the first signal application module (321). The first SIM (301) can be switched to an activated state in response to receiving the high signal. For another example, when selecting the second SIM (302), the processor (120) may control the first signal application module (321) to transmit a low signal to the first SIM (301) through the level shifter (311), and may not select the first SIM (301). The first SIM (301) may be switched to an inactive state in response to receiving the low signal.According to one embodiment, the electronic device (101) may, in response to the selection of the first SIM (301), perform a communication connection based on the first SIM (301) through the communication module (190).

[0061] For another example, when a second SIM (302) is selected from among a plurality of SIMs, the processor (120) can perform a communication connection based on the second SIM (302). For example, the processor (120) and the second SIM (302) can be electrically connected by a second signal application module (322). The second SIM (302) can be directly connected to the second signal application module (322). The electronic device (101) can control a signal transmitted to the second SIM (302) under the control of the second signal application module (322). The processor (120) can select the second SIM (302) based on the second signal application module (322), and in response to the second SIM (302) being selected, can perform a communication connection based on the second SIM (302) through the communication module (190).

[0062] According to one embodiment, the processor (120) can control the power supply to each of the components through the power module (330). Referring to FIG. 3, the power module (330) can be electrically connected to the processor (120), the level shifter (311), the first SIM (301), and the second SIM (302), and can control the power supply to each component. According to one embodiment, the processor (120) can supply power to the level shifter (311) and the first SIM (301) based on the power module (330) in response to the selection of the first SIM (301). The processor (120) can supply power to the first SIM (301) based on the power module (330) while transmitting a signal to the first SIM (301) through the level shifter (311). Upon selection of the first SIM (301), the processor (120) may cut off power supply to the second SIM (302) (e.g., the remaining unselected SIM). In one embodiment, the processor (120) may supply power to the second SIM (302) based on the power module (330) in response to selection of the second SIM (302). Upon selection of the second SIM (302), the processor (120) may also cut off power supply to the first SIM (301).

[0063] According to another embodiment, the electronic device (101) can supply power set to the first SIM (301) and the second SIM (302) periodically or aperiodically. For example, the electronic device (101) can maintain the first SIM (301) and the second SIM (302) in a standby state by continuously supplying power. According to another embodiment, when the SIM card is switched, since the SIM to be switched is maintained in a standby state, the electronic device (101) can perform a change in the communication connection more quickly when the SIM card is switched.

[0064] According to one embodiment, the electronic device (101) may include a first SIM (301) that corresponds to a physical SIM and is inserted from the outside, and a second SIM (302) that is built into an internal space of the electronic device (101) and is implemented in the form of a chip. For example, the first SIM (301) may be a physical SIM card that may be at least partially mounted in a SIM tray (e.g., the SIM tray (210) of FIG. 2). The first SIM (301) may be electrically connected to a level shifter (311) when the SIM tray is coupled to the electronic device (101), and may be connected to the processor (120) through the level shifter (311). When the first SIM (301) is selected, the processor (120) can control the first signal application module (321) to activate the first SIM (301) and perform a communication connection based on the activated first SIM (301). When the second SIM (302) is selected, the processor (120) can control the second signal application module (322) to activate the second SIM (302) and perform a communication connection based on the activated second SIM (302).

[0065] According to one embodiment, each SIM may be directly or indirectly connected to a respective signal activation module, and under the control of each signal activation module, whether or not to activate may be determined.

[0066] According to one embodiment, when the first SIM (301) is selected, the electronic device (101) can control the first signal application module (321) to activate the first SIM (301) and supply the set power to the first SIM (301) through the power module (330). According to one embodiment, when the second SIM (302) is selected, the electronic device (101) can control the second signal application module (322) to activate the second SIM (302) and supply the set power to the second SIM (302) through the power module (330).

[0067] According to one embodiment, the electronic device (101) may provide a method of activating only the selected SIM to prevent signal collisions due to the communication connection when selecting one SIM for communication connection. The electronic device (101) may activate the selected SIM based on a signal application module and supply power to the selected SIM based on a power module (330). The electronic device (101) may prevent collisions between communication signals when performing SIM-based communication. Since the electronic device (101) utilizes the signal application modules (321, 322) rather than a switch (e.g., an analog switch) when selecting one SIM from among a plurality of SIMs, the switch may be eliminated from the internal components. According to one embodiment, since at least one switch component is eliminated from the electronic device (101), the design cost for the electronic device (101) may be reduced, and the internal space of the electronic device (101) may be secured.

[0073] According to one embodiment, when the instructions are individually or collectively executed by the processor (120), the electronic device (101) may, in response to selection of the second SIM (302), supply power to the second SIM (302) based on the power module (330), and in response to selection of the second SIM (302), cut off power to the first SIM (301) based on the power module (330).

[0080] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0081] According to one embodiment, operations 401 through 407 may be understood to be performed by a processor (e.g., processor (120) of FIG. 3) of an electronic device (e.g., electronic device (101) of FIG. 1). The electronic device of FIG. 4 may be at least partially similar to the electronic device (101) of FIG. 1 or may further include other embodiments of the electronic device (101).

[0082] According to one embodiment, the electronic device (101) may include a plurality of SIMs (e.g., the first SIM (301) and / or the second SIM (302) of FIG. 3), and may select one SIM from the plurality of SIMs and perform a communication connection for the selected SIM. The first SIM (301) may include a physical pSIM, and whether it is activated may be determined based on a signal supplied through a level shifter (e.g., the level shifter (311) of FIG. 3). The second SIM (302) may include an eSIM built into the electronic device (101), and whether it is activated may be determined under the control of a second signal application module (e.g., the second signal application module (312) of FIG. 3). According to one embodiment, a plurality of SIMs, each of which may be directly or indirectly connected to a signal application module, may be configured such that, under the control of each signal application module, at least one SIM among the plurality of SIMs may be activated.

[0083] In operation 401, the processor (120) may transmit a first signal to the level shifter (311) through the first signal application module (311) in response to the selection of the first SIM (301) so as to activate the first SIM (301). For example, the level shifter (311) may be arranged between the processor (120) and the first SIM (301), and the level shifter (311) may be controlled by the first signal application module (311). The processor (120) may control the first signal application module (311) to transmit a first signal to the first SIM (301) through the level shifter (311). The first signal may include a High signal for activating the first SIM (301). For example, the first SIM (301) may be at least partially activated in response to receiving the first signal. The electronic device (101) may perform a first communication connection based on the activated first SIM (301).

[0084] In operation 403, the processor (120) may supply power to the selected first SIM (301) based on a power module (e.g., the power module (330) of FIG. 3). The electronic device (101) may perform a first communication connection based on the first SIM (301) to which power is supplied.

[0085] In operation 405, the processor (120) may transmit a second signal, different from the first signal, to the second SIM (302) via the second signal application module (312) in response to the selection of the first SIM (301) so as to deactivate the second SIM (302). The second signal may include a low signal for deactivating the second SIM (302). For example, the second SIM (302) may be deactivated in response to receiving the second signal. The electronic device (101) may not connect a second communication based on the deactivated second SIM (302).

[0086] In operation 407, the processor (120) may cut off power to the second SIM (302) based on the power module (330). The electronic device (101) may not perform a second communication connection based on the second SIM (302) that is not supplied with power.

[0087] According to one embodiment, when one SIM (e.g., the first SIM (301)) is selected from among a plurality of SIMs, the electronic device (101) can control the first signal application module (311) to transmit a first signal (e.g., a high signal) to the selected SIM and activate the first SIM (301).

The electronic device (101) may not perform a second communication connection based on the second SIM (302).

[0089] According to one embodiment, the electronic device (101) can perform a communication connection based on the first SIM (301) while the first SIM (301) is activated under the control of the first signal application module (311). The electronic device (101) can periodically or aperiodically check the strength value of the communication signal in relation to the communication based on the first SIM (301). For example, if the strength value of the communication signal is maintained within a set range, it can be confirmed that the communication based on the first SIM (301) is performed smoothly without interference from the surroundings. For another example, if the strength value of the communication signal falls below a set threshold, it can be confirmed that the communication based on the first SIM (301) is in a state where communication performance is degraded due to interference from the surroundings. The electronic device (101) may, in response to a situation where the strength value of a communication signal by the first SIM (301) falls below a set threshold, transmit a second signal (e.g., a low signal) that is different from the first signal (e.g., a high signal) to the second SIM (302) (e.g., the other SIM).

[0090] According to one embodiment, when performing communication based on the first SIM (301), the electronic device (101) may determine that communication performance is degraded due to interference (e.g., the strength value of the communication signal is determined to be below a set threshold value), and in this case, the electronic device may transmit a second signal to the remaining SIMs (e.g., the second SIM (302)) so that the remaining SIMs, other than the first SIM (301), are deactivated. For example, the electronic device (101) may switch the remaining SIMs to a deactivated state, excluding the selected SIM, in response to the deterioration of communication performance due to interference.

[0099] For example, when the 1-1 SIM (601) is selected, the processor (120) can control the first signal application module (621) to supply a first signal (e.g., a high signal) to the 1-1 SIM (601) through the first level shifter (611), thereby activating the 1-1 SIM (601). The electronic device (101) can supply power to the 1-1 SIM (601) based on the power module (330) in response to the selection of the 1-1 SIM (601).

[0100] For example, when the 1-2 SIM (602) is selected, the processor (120) can control the second signal application module (622) to supply a first signal (e.g., a high signal) to the 1-2 SIM (602) through the second level shifter (612), thereby activating the 1-2 SIM (602). The electronic device (101) can supply power to the 1-2 SIM (602) based on the power module (330) in response to the selection of the 1-2 SIM (602).

[0102] According to one embodiment, the electronic device (101) can supply the set power to a selected SIM based on the power module (330). For example, when the 1-1 SIM (601) is selected, the processor (120) can supply the set power to the 1-1 SIM (601) and block the power supply to the remaining SIMs (e.g., the 1-2 SIM (602), the 2nd SIM (603)). For example, when the 2nd SIM (603) is selected, the processor (120) can supply the set power to the 2nd SIM (603) and block the power supply to the remaining SIMs (e.g., the 1-1 SIM (601), the 1-2 SIM (602)).
