Description

Method for requesting capability limitation in an electronic device including multiple subscriber identification modules (SIMs) and electronic device

[0001] One embodiment relates to a method for requesting capability limitation in an electronic device comprising a plurality of subscriber identification modules and an electronic device.

[0002] An electronic device comprising multiple Subscriber Identification Modules (SIMs) can communicate with the base station of each SIM using each SIM. Each SIM within the electronic device may share hardware components of the electronic device to communicate with each base station. Consequently, when the electronic device uses each SIM simultaneously, the capability of the electronic device regarding one SIM (e.g., the frequency used by one SIM) may be limited by the operation of the other SIM.

[0003] In some cases, the electronic device's ability to use one SIM may be excessively limited by the operation of the other SIM. In this case, the electronic device may be unable to provide seamless service to the user due to the excessively limited ability. For example, call drops or service latency may occur. Additionally, handovers may fail or handover latency may be prolonged due to the excessively limited ability.

[0004] In addition, if the capability of the electronic device regarding one SIM is limited by the operation of the other SIM of the electronic device, frequent capability changes may occur in the electronic device, and frequent registration procedures may occur in the network due to the frequent capability changes of the electronic device.

[0005] According to one embodiment, an electronic device can be provided that prevents the capability of an electronic device regarding one SIM from being limited by the operation of the other SIM.

[0006] According to one embodiment, by performing cell selection (or cell re-selection) with priority given to a cell capable of controlling the capabilities of the electronic device, an electronic device can be provided that can resolve problems that may arise from frequent capability changes.

[0007] According to one embodiment, the electronic device may include at least one processor comprising a memory for storing instructions and a processing circuit. When the instructions are executed by the at least one processor, the electronic device may perform the following operations: comparing the priority of a first service performed through a first communication network corresponding to the first SIM and the priority of a second service performed through a second communication network corresponding to the second SIM in the respective connection state of the first SIM and the second SIM of the electronic device; identifying at least one of an interference cell or a frequency band that interferes with the first service when the priority of the first service is higher than the priority of the second service; and transmitting a restriction request for at least one of the identified interference cell or the identified frequency band to the base station of the second SIM.

[0008] According to one embodiment, the electronic device may include at least one processor comprising a memory for storing instructions and a processing circuit. When the instructions are executed by the at least one processor, the electronic device may perform: an operation to determine whether the priority of a first service performed through a first communication network corresponding to the first SIM is the highest priority in the case where the first SIM of the electronic device is in a connected state and the second SIM of the electronic device is in an idle state; an operation to determine whether there is a first cell among the cells associated with the second SIM when the priority of the first service is the highest priority (wherein the first cell corresponds to a cell capable of limiting the ability of a terminal supporting multi-SIM without interfering with the first service); and an operation to attempt to camp on the first cell through the second SIM when it is determined that there is a first cell.

[0009] According to one embodiment, a method of operating an electronic device may include comparing the priority of a first service performed through a first communication network corresponding to a first SIM of the electronic device with the priority of a second service performed through a second communication network corresponding to a second SIM of the electronic device; identifying at least one of an interference cell or frequency band that interferes with the first service when the priority of the first service is higher than the priority of the second service; and transmitting a restriction request for at least one of the identified interference cell or the identified frequency band to a base station of the second SIM.

[0010] According to one embodiment, a method of operating an electronic device may include, in a case where the first SIM of the electronic device is in a connected state and the second SIM of the electronic device is in an idle state, an operation of determining whether the priority of a first service performed through a first communication network corresponding to the first SIM is the highest priority; if the priority of the first service is the highest priority, an operation of determining whether there is a first cell among the cells associated with the second SIM (wherein the first cell corresponds to a cell capable of limiting the ability of a terminal supporting multi-SIM without interfering with the first service); and if it is determined that there is a first cell, an operation of attempting to camp on the first cell through the second SIM.

[0011] According to one embodiment, a computer-readable non-transient recording medium may store software for causing an electronic device to perform operations. The operations may include an operation of comparing the priority of a first service performed through a first communication network corresponding to a first SIM of the electronic device with the priority of a second service performed through a second communication network corresponding to a second SIM of the electronic device; an operation of identifying at least one of an interference cell or frequency band that interferes with the first service when the priority of the first service is higher than the priority of the second service; and an operation of transmitting a restriction request for at least one of the identified interference cell or the identified frequency band to a base station of the second SIM.

[0044] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) through a server (108) connected to a second network (199). Each of the external electronic devices (102, or 104) may be the same or different type of device as the electronic device (101). According to one embodiment, all or part of the operations performed on the electronic device (101) may be performed on one or more of the external electronic devices (102, 104, or 108). For example, if the electronic device (101) needs to perform a function or service automatically or in response to a request from a user or another device, the electronic device (101) may request one or more external electronic devices to perform at least part of the function or service instead of performing the function or service itself or additionally.

[0056] According to one embodiment, the first-1 RFIC (222-1) (or the first RFIC (222)) can convert a baseband signal generated by the processor (210) during transmission into a radio frequency (RF) signal of a frequency band (e.g., about 700 MHz to about 3 GHz) used in the first cellular network (292). During reception, the RF signal can be received or acquired from the first cellular network (292) through the first antenna module (242) and can be preprocessed through the first RFFE (232). The first-1 RFIC (222-1) (or the first RFIC (222)) can convert the preprocessed RF signal into a baseband signal so that it can be processed by the processor (210).

[0057] According to one embodiment, the first-2 RFIC (222-2) (or the first RFIC (222)) can convert a baseband signal generated by the processor (210) during transmission into an RF signal of the Sub6 band (e.g., about 6 GHz or lower) used in the second cellular network (294) (hereinafter, 5G Sub6 RF signal). During reception, the 5G Sub6 RF signal can be received or acquired from the second cellular network (294) through the second antenna module (244) and can be preprocessed through the second RFFE (234). The first-2 RFIC (222-2) (or the first RFIC (222)) can convert the preprocessed 5G Sub6 RF signal into a baseband signal so that it can be processed by the processor (210).

[0058] According to one embodiment, the third RFIC (226) can convert a baseband signal generated by the processor (210) into an RF signal of the 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network (294) (hereinafter, 5G Above6 RF signal). Upon reception, the 5G Above6 RF signal may be received or acquired from the second cellular network (294) through the third antenna module (246) (e.g., antenna (248)) and may be preprocessed through the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a baseband signal so that it can be processed by the processor (210). According to one embodiment, the third RFFE (236) may be formed as part of the third RFIC (226).

[0059] According to one embodiment, the electronic device (101) may include a second RFIC (224) separately from or at least as part of the third RFIC (226). In this case, the second RFIC (224) may convert a baseband signal generated by the processor (210) into an RF signal (hereinafter referred to as an IF signal) in an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received or acquired from the second cellular network (294) through the third antenna module (246) (e.g., antenna (248)) and may be converted into an IF signal by the third RFIC (226). The second RFIC (224) can convert the IF signal into a baseband signal so that the processor (210) can process it.

[0060] According to one embodiment, at least one of the first antenna module (242) or the second antenna module (244) may be omitted or combined with another antenna module to process RF signals of a plurality of corresponding bands.

[0061] According to one embodiment, the third RFIC (226) and the antenna (248) may be placed on the same substrate to form a third antenna module (246). For example, the processor (120) may be placed on the first substrate (e.g., main PCB). In this case, the third RFIC (226) may be placed on a portion of the second substrate (e.g., sub PCB) separate from the first substrate (e.g., bottom surface), and the antenna (248) may be placed on another portion of the second substrate (e.g., sub PCB) (e.g., top surface), thereby forming the third antenna module (246). By placing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line between them. This can reduce the loss (e.g., attenuation) of signals in the high-frequency band (e.g., about 6 GHz to about 60 GHz) used for 5G network communication by the transmission line. As a result, the electronic device (101) can improve the quality or speed of communication with the second cellular network (294) (e.g., 5G network).

[0062] According to one embodiment, the antenna (248) may be formed as an antenna array comprising a plurality of antenna elements that can be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). During transmission, each of the plurality of phase shifters (238) can change the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device (101) (e.g., a base station of a 5G network) through the corresponding antenna element. During reception, each of the plurality of phase shifters (238) can change the phase of a 5G Above6 RF signal received from the outside (e.g., a base station of a 5G network) through the corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (101) and the outside.

[0063] The second cellular network (294) may be operated independently of the first cellular network (292) (e.g., stand-alone (SA)) or connected (e.g., non-stand-alone (NSA)). For example, the 5G network may only have an access network (e.g., 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, after the electronic device (101) accesses the access network of the 5G network, it may access an external network (e.g., the Internet) under the control of the core network of the legacy network (e.g., evolved packed core (EPC)). Protocol information for communication with the legacy network (e.g., LTE protocol information) or protocol information for communication with the 5G network (e.g., new radio (NR) protocol information) may be stored in memory (e.g., memory (130) of FIG. 1) and accessed by the processor (210).

[0064]

[0065] FIG. 3 is a diagram illustrating an example of the operation of an electronic device in the connection state of each of a plurality of SIMs of an electronic device according to one embodiment.

[0066] Referring to FIG. 3, an electronic device (301) according to one embodiment (e.g., the electronic device (101) of FIG. 1 or the electronic device (201) of FIG. 2) may include a first SIM (subscriber identification module) (310) and a second SIM (320).

[0067] The first SIM (310) may correspond to a SIM subscribed to a telecommunications operator of the first telecommunications network. The electronic device (301) may use the first SIM (310) to connect to or link to a base station of the first telecommunications network (e.g., the first base station (380) of FIG. 3). The first SIM (310) may be in a connected state (e.g., a radio resource control (RRC) connected state). The connected state of the first SIM (310) (e.g., an RRC connected state) may indicate, for example, a state in which an RRC connection is formed between the electronic device (301) (or the first SIM (310)) and the first base station (380).

[0068] The second SIM (320) may correspond to a SIM subscribed to a telecommunications operator of the second telecommunications network. The electronic device (301) may use the second SIM (320) to connect to or link to a base station of the second telecommunications network (e.g., the second base station (390) of FIG. 3). The second SIM (320) may be in a connected state (e.g., an RRC connected state). The connected state of the second SIM (320) (e.g., an RRC connected state) may indicate, for example, a state in which an RRC connection is formed between the electronic device (301) (or the second SIM (320)) and the second base station (390).

[0069] According to one embodiment, the first communication network and the second communication network may each include an LTE network or an NR network. Depending on the implementation, the first communication network and the second communication network may each include a network that supports EN-DC (EUTRA (evolved-universal mobile telecommunications system terrestrial radio access) NR dual connectivity).

[0070] According to one embodiment, in a connection state of the first SIM (310) (e.g., RRC connection state), the electronic device (301) may perform or provide a service (hereinafter referred to as the first service) by connecting to a first communication network corresponding to the first SIM (310). The electronic device (301) may perform or provide the first service through the first communication network (or the first SIM (310)). The first service may include, for example, at least one of a call service, a URLLC service, or an Internet PDN (packet data network) service. The call service may include, for example, an IMS (internet protocol multimedia subsystem)-based VoLTE (voice over LTE) or VoNR (voice over NR), but is not limited thereto. The URLLC service may include, for example, a virtual reality (or augmented reality) service requiring real-time capabilities or a game service requiring real-time capabilities, but is not limited thereto. The Internet PDN service may represent a service that the electronic device (301) can perform or provide by connecting to the Internet through the PDN. Internet PDN services may include, for example, services that display information through a web browser or video playback services, but are not limited thereto.

[0071] According to one embodiment, in a connection state of the second SIM (320) (e.g., RRC connection state), the electronic device (301) may perform or provide a service (hereinafter referred to as the second service) by connecting to a second communication network corresponding to the second SIM (320). The electronic device (301) may perform or provide the second service through the second communication network (or the second SIM (320)). The second service may include, for example, at least one of a call service, a URLLC service, or an Internet PDN service.

[0072] According to one embodiment, the call service, the URLLC service, and the Internet PDN service may each have a priority. For example, the priority of the call service and the URLLC service may be equal to each other and higher than the priority of the Internet PDN service. In other words, the call service and the URLLC service may have the highest priority, and the Internet PDN service may have the lowest priority. As another example, among the call service, the URLLC service, and the Internet PDN service, the URLLC service may have the highest priority, the call service may have the second highest priority, and the Internet PDN service may have the lowest priority. As yet another example, among the call service, the URLLC service, and the Internet PDN service, the call service may have the highest priority, the URLLC service may have the second highest priority, and the Internet PDN service may have the lowest priority.

[0073] The aforementioned call service, URLLC service, and / or Internet PDN service are merely examples of the first service and the second service, respectively, and the first service and the second service are not limited to the call service, URLLC service, and / or Internet PDN service.

[0074] When the electronic device (301) performs the first service and the second service, either of the services performed may affect (e.g., interfere with) the other.

[0075] According to one embodiment, when the electronic device (301) performs a first service and a second service simultaneously, it can identify an interfering cell and / or frequency band that may affect a high-priority service among one or more cells and / or one or more frequency bands for performing a low-priority service. The electronic device (301) can transmit a restriction request for the identified interfering cell and / or identified frequency band to the base station of the low-priority service.

[0076] For example, the electronic device (301) may perform a call service (or URLLC service) through a first communication network and perform an Internet PDN service through a second communication network. The call service (or URLLC service) may have a higher priority than the Internet PDN service. The electronic device (301) may identify one or more interfering cells and / or one or more frequency bands among one or more cells and / or one or more frequency bands for performing the Internet PDN service that may interfere with the call service (or URLLC service). The electronic device (301) may transmit a restriction request for the identified interfering cells and / or identified frequency bands via a UAI (UE assistance information) message to a base station of a lower priority service (e.g., a second base station (390) of the second SIM (320)). The second base station (390) may identify the interfering cells and / or frequency bands for which a restriction request was made via the UAI message received from the electronic device (301) and may reallocate wireless resources for the Internet PDN service by avoiding the identified interfering cells and / or frequency bands.

[0077] According to one embodiment, the UAI message may include, for example, a field regarding a capability restriction request of the electronic device (301) (e.g., the MUSIM-CapRestriction field of 3GPP TS 38.331). The electronic device (301) may transmit a restriction request for an identified interference cell and / or an identified frequency band to the base station of the second SIM (320) (e.g., the second base station (390) of FIG. 3) through a field of the UAI message (e.g., the MUSIM-CapRestriction field of 3GPP TS 38.331). Table 1 below shows an example of a field regarding a capability restriction request (e.g., the MUSIM-CapRestriction field).

[0078] MUSIM-CapRestriction-r18 ::= SEQUENCE {musim-Cell-SCG-ToRelease-r18 MUSIM-Cell-SCG-ToRelease-r18 OPTIONAL,musim-CellToAffectList-r18 MUSIM-CellToAffectList-r18 OPTIONAL,musim-AffectedBandsList-r18 MUSIM-AffectedBandsList-r18 OPTIONAL,musim-AvoidedBandsList-r18 MUSIM-AvoidedBandsList-r18 OPTIONAL,musim-MaxCC-r18 MUSIM-MaxCC-r18 OPTIONAL}

[0079]

[0080] The first parameter (e.g., musim-Cell-SCG-ToRelease-r18) may indicate the preference of the electronic device (301) for the secondary cell group (SCG) and / or serving cell(s) to be released, excluding the primary cell (pcell), for example, for the multi-SIM (MUSIM) operation of the electronic device (301). The MUSIM operation may include, for example, a state in which the electronic device (301) performs multiple services (e.g., a first service and a second service) simultaneously. The electronic device (301) may transmit a release request for the SCG and / or serving cell that may affect the high-priority service to the base station of the low-priority service by transmitting a UAI message containing the first parameter to the base station of the low-priority service.

[0081] For example, an electronic device (301) may use EN-DC to provide a second service of lower priority (e.g., Internet PDN service). In this case, the frequency band of N78 in EN-DC may be used as SCG. The electronic device (301) may be allocated the frequency band of N78 to perform a first service of higher priority (e.g., call service or URLLC service). Due to the performance of the second service, the electronic device (301) may lack an RF path for the first service. The first service of higher priority may be affected by the second service of lower priority. The electronic device (301) may transmit a request to release the SCG of N78 of the second service to the second base station (390) of the second SIM (320) so that the impact on the first service can be minimized. The electronic device (301) can set N78 to a first parameter (e.g., musim-Cell-SCG-ToRelease-r18) and can transmit a UAI message containing the first parameter with N78 set to a second base station (390). The second base station (390) can release the SCG of N78 of the second service.

[0082] The second parameter (e.g., musim-CellToAffectList-r18) may indicate the preference of the electronic device (301) for a temporary capability limit (e.g., limit on the number of MIMO layers) of the serving cell(s) for the MUSIM operation of the electronic device (301). The electronic device (301) may transmit a request to the base station of the low-priority service to limit the number of MIMO layers of the low-priority service by transmitting a UAI message containing the second parameter to the base station of the low-priority service.

[0083] For example, the electronic device (301) may use a total of four MIMO layers and may use all four MIMO layers to perform a low-priority second service. The electronic device (301) may require two MIMO layers to perform a high-priority first service. If the electronic device (301) uses all four MIMO layers to perform a low-priority second service, the second service may affect the first service. In one embodiment, the electronic device (301) may reduce the number of MIMO layers used for the second service to two so that the impact on the first service is minimized. The electronic device (301) may set the number of MIMO layers in the second parameter (e.g., musim-CellToAffectList-r18) to two. The electronic device (301) may transmit a request to limit the number of MIMO layers for the second service to the second base station (390). The electronic device (301) can transmit a UAI message including a second parameter in which the number of MIMO layers of the second service is set to 2 to the second base station (390). The second base station (390) can limit the number of MIMO layers for the second service to 2.

[0084] A third parameter (e.g., musim-AvoidedBandsList-r18) may indicate, for example, the electronic device (301)'s preference for combination(s) of bands to be avoided and / or band(s). The electronic device (301) may transmit a request to restrict frequency bands for a low-priority service to the base station of the low-priority service by transmitting a UAI message containing the third parameter to the base station of the low-priority service.

[0085] For example, the first UL band of a second service with a low priority may affect the DL of a first service with a high priority. In this case, the electronic device (301) may set the first UL band of the second service in a third parameter (e.g., musim-AvoidedBandsList-r18) so that the impact on the first service is minimized. The electronic device (301) may transmit a restriction request for the first UL band of the second service to the second base station (390). The electronic device (301) may transmit a UAI message to the second base station (390) that includes the third parameter in which the first UL band of the second service is set. The second base station (390) may allocate other UL bands for the second service, excluding the first UL band set in the third parameter within the UAI message.

[0086] The fourth parameter (e.g., musim-MaxCC-r18) may represent, for example, the maximum number of component carriers (CC) of the electronic device (301) per DL / UL. The electronic device (301) may transmit a request to the base station of the low-priority service to limit the maximum number of CCs for the low-priority service by transmitting a UAI message containing the fourth parameter to the base station of the low-priority service.

[0087] For example, the total number of available CCs (e.g., x) may be determined for the electronic device (301). Among the total number of available CCs of the electronic device (301), n ​​CCs may be used to perform a first service of high priority. The electronic device (301) may calculate the total number of CCs for the second service (e.g., y) by subtracting n from the total number of available CCs so that the impact of a second service of low priority is minimized on the first service. The electronic device (301) may transmit a request to limit the total number of CCs for the second service to the second base station (390). The electronic device (301) may set y in the fourth parameter (e.g., musim-MaxCC-r18) and transmit a UAI message containing the fourth parameter with y set to the second base station (390). The second base station (390) may allocate CCs for performing the second service within y.

[0088]

[0089] FIG. 4 is a flowchart illustrating an example of a method in which an electronic device according to one embodiment requests a base station via a UAI message to restrict at least one of a cell or frequency band that affects the service.

[0090] In the example illustrated in FIG. 4, the first SIM (310) and the second SIM (320) may each be in a connected state (e.g., an RRC connected state). The electronic device (301) may perform the first service and the second service. Each of the first service and the second service may correspond to any one of the call service, URLLC service, and Internet PDN service described through FIG. 3, for example.

[0091] In the example illustrated in Fig. 4, the call service and URLLC service may have the highest priority, and the Internet PDN service may have the lowest priority.

[0092] Referring to FIG. 4, in operation 411, the electronic device (301) can compare the priority of the first service with the priority of the second service.

[0093] If the priority of the first service is higher than the priority of the second service, in operation 413, the electronic device (301) can determine whether the electronic device (301) is in a stationary state. For example, the electronic device (301) can determine whether the electronic device (301) is in a stationary state or a moving state through an accelerometer and / or a gyroscope.

[0094] When the electronic device (301) determines that the electronic device (301) is in a stationary state (Operation 413-Example), in Operation 415, it may identify at least one of a first interference cell or a first frequency band. The first interference cell may include a cell capable of interfering with a primary cell (pcell) for a first service (e.g., a pcell used by the electronic device (301) to perform the first service). The first interference cell may include, for example, a cell (or SCG) having a frequency band that overlaps with the pcell for the first service among the cells for the second service, but is not limited thereto. The first frequency band may include a frequency band capable of affecting the pcell for the first service. The first frequency band may include, for example, a frequency band for the second service that may affect the UL and / or DL ​​of the pcell for the first service, but is not limited thereto.

[0095] In operation 417, the electronic device (301) may transmit a UAI message containing at least one of the identified first interference cell or the identified first frequency band to a second base station (390) (e.g., a base station of a second service having a lower priority). The electronic device (301) may transmit a restriction request for at least one of the identified first interference cell or the identified first frequency band to the second base station (390).

[0096] For example, while the electronic device (301) is performing a second service, a pcell for performing a first service may be allocated to the electronic device (301). Due to the performance of the second service, the electronic device (301) may lack an RF path for performing the first service. In this case, the electronic device (301) can identify a cell (or SCG) that overlaps with the pcell of the first service among the cells for the second service. The electronic device (301) can set the identified cell (or SCG) in a first parameter (e.g., musim-Cell-SCG-ToRelease-r18) and transmit a UAI message containing the first parameter in which the identified cell (or SCG) is set to a second base station (390).

[0097] As another example, the electronic device (301) may determine that the first UL band of the second service interferes with the DL of the first service. The electronic device (301) may set the first UL band of the second service in a third parameter (e.g., musim-AvoidedBandsList-r18). The electronic device (301) may transmit a UAI message containing the third parameter in which the first UL band is set to the second base station (390).

[0098] According to an embodiment, the number of MIMO layers for the execution of the first service may be insufficient due to the execution of the second service. The electronic device (301) may transmit a request to limit the number of MIMO layers for the second service to the second base station (390) via a UAI message including a second parameter (e.g., musim-CellToAffectList-r18). According to an embodiment, n CCs may be used for the first service. When the total number of CCs available to the electronic device (301) is x, the electronic device (301) may calculate the total number of CCs for the second service (e.g., y) by subtracting n from x. The electronic device (301) may transmit a request to limit the total number of CCs for the second service to the second base station (390) via a UAI message including a fourth parameter (e.g., musim-MaxCC-r18).

[0099] If the electronic device (301) determines that the electronic device (301) is not in a stationary state (or determines that the electronic device (301) is in a moving state) (operation 413-No), in operation 419, the electronic device (301) may identify at least one of a second interference cell or a second frequency band. The second interference cell may include a cell capable of interfering with at least one of the frequencies for the first service (e.g., the frequency used to perform the first service) or the frequencies of neighboring cells. The second interference cell may include, for example, but is not limited to, a cell (or SCG) having a frequency band that overlaps with one or more of the cells for the first service and / or neighboring cells. The second frequency band may include a frequency band capable of interfering with at least one of the frequencies for the first service or the frequencies of neighboring cells. If the electronic device (301) is moving, the neighboring cell may become the pcell of the first SIM (310) by handover. The electronic device (301) can identify cells and / or frequency bands that may interfere with the frequency used to perform the first service when the electronic device (301) is moving, as well as cells and / or frequency bands that may interfere with the frequency of neighboring cells of the serving cell of the first SIM (310).

[0100] In operation 421, the electronic device (301) may transmit a UAI message to the second base station (390) including at least one of the identified second interference cell or the identified second frequency band. The electronic device (301) may transmit a restriction request for at least one of the identified second interference cell or the identified second frequency band to the second base station (390).

[0101] For example, the electronic device (301) may transmit a restriction request for at least one of the identified second interference cell or the identified second frequency band to the second base station (390) via a UAI message including a first parameter and / or a third parameter. According to an embodiment, the electronic device (301) may transmit a restriction request for the number of MIMO layers for the second service to the second base station (390) via a UAI message including a second parameter, or transmit a restriction request for the total number of CCs for the second service to the second base station (390) via a UAI message including a fourth parameter.

[0102] If the priority of the first service and the priority of the second service are the same, in operation 423, the electronic device (301) can determine whether the electronic device (301) is in a stationary state. For example, the electronic device (301) can determine whether the electronic device (301) is in a stationary state or a moving state through a gyroscope sensor and / or an accelerometer sensor.

[0103] When the electronic device (301) determines that the electronic device (301) is in a stationary state (Operation 423-Yes), in Operation 425, the electronic device (301) may identify at least one of a third interference cell or a third frequency band. The third interference cell may represent a cell capable of interfering with the pcell for the service performed first, and the third frequency band may represent a frequency band capable of interfering with the pcell for the service performed first. For example, if the first service is performed before the second service, the electronic device (301) may identify at least one of an interference cell or frequency band that interferes with the pcell for the first service. If the second service is performed before the first service, the electronic device (301) may identify at least one of an interference cell or frequency band that interferes with the pcell for the second service.

[0104] In operation 427, the electronic device (301) may transmit a UAI message containing at least one of the identified third interference cell or the identified third frequency band to the base station of the service performed later. The electronic device (301) may transmit a restriction request for at least one of the identified third interference cell or the identified third frequency band to the base station of the service performed later.

[0105] For example, the electronic device (301) may transmit a restriction request for at least one of the identified third interference cell or the identified third frequency band to the base station of the later service via a UAI message including a first parameter and / or a third parameter. According to an embodiment, the electronic device (301) may transmit a restriction request for the number of MIMO layers for the later service to the base station of the later service via a UAI message including a second parameter, or transmit a restriction request for the total number of CCs for the later service to the base station of the later service via a UAI message including a fourth parameter.

[0106] When the electronic device (301) determines that the electronic device (301) is not in a stationary state (or determines that the electronic device (301) is in a moving state) (operation 423-No), in operation 429, the electronic device (301) may identify at least one of a fourth interference cell or a fourth frequency band. The fourth interference cell may represent a cell capable of interfering with at least one of the frequency for a first-hand service or the frequency of a neighboring cell, and the fourth frequency band may represent a frequency band capable of interfering with at least one of the frequency for a first-hand service or the frequency of a neighboring cell.

[0107] In operation 431, the electronic device (301) may transmit a UAI message containing at least one of the identified fourth interference cell or the identified fourth frequency band to the base station of the service performed later. The electronic device (301) may transmit a restriction request for at least one of the identified fourth interference cell or the identified fourth frequency band to the base station of the service performed later.

[0108] For example, the electronic device (301) may transmit a restriction request for at least one of the identified fourth interference cell or the identified fourth frequency band to the base station of the later service via a UAI message including a first parameter and / or a third parameter. According to an embodiment, the electronic device (301) may transmit a restriction request for the number of MIMO layers for the later service to the base station of the later service via a UAI message including a second parameter, or transmit a restriction request for the total number of CCs for the second service to the base station of the later service via a UAI message including a fourth parameter.

[0109] If the priority of the first service is lower than the priority of the second service, in operation 433, the electronic device (301) can determine whether the electronic device (301) is in a stationary state. For example, the electronic device (301) can determine whether the electronic device (301) is in a stationary state or a moving state through an accelerometer and / or a gyroscope.

[0110] When the electronic device (301) determines that the electronic device (301) is in a stationary state (Operation 433-Yes), in Operation 435, the electronic device (301) may identify at least one of a fifth interference cell or a fifth frequency band. The fifth interference cell may represent a cell capable of interfering with a pcell for a second service (e.g., a pcell used by the electronic device (301) to perform the second service), and the fifth frequency band may represent a frequency band capable of interfering with a pcell for a second service.

[0111] In operation 437, the electronic device (301) may transmit a UAI message containing at least one of the identified fifth interference cell or the identified fifth frequency band to the first base station (380) (e.g., a base station of the first service having low priority). The electronic device (301) may transmit a restriction request for at least one of the identified fifth interference cell or the identified fifth frequency band to the first base station (380).

[0112] For example, the electronic device (301) may transmit a restriction request for at least one of the identified fifth interference cell or the identified fifth frequency band to the first base station (380) via a UAI message including a first parameter and / or a third parameter. According to an embodiment, the electronic device (301) may transmit a restriction request for the number of MIMO layers for the first service to the first base station (380) via a UAI message including a second parameter, or transmit a restriction request for the total number of CCs for the first service to the first base station (380) via a UAI message including a fourth parameter.

[0113] If the electronic device (301) determines that the electronic device (301) is not in a stationary state (or determines that the electronic device (301) is in a moving state) (operation 433-No), in operation 439, the electronic device (301) may identify at least one of a sixth interference cell or a sixth frequency band. The sixth interference cell may represent a cell capable of interfering with at least one of the frequencies for the second service or the frequencies of neighboring cells, and the sixth frequency band may represent a frequency band capable of interfering with at least one of the frequencies for the second service or the frequencies of neighboring cells.

[0114] In operation 441, the electronic device (301) may transmit a UAI message to the first base station (380) including at least one of the identified sixth interference cell or the identified sixth frequency band. The electronic device (301) may transmit a restriction request for at least one of the identified sixth interference cell or the identified sixth frequency band to the first base station (380).

[0115] For example, the electronic device (301) may transmit a restriction request for at least one of the identified sixth interference cell or the identified sixth frequency band to the first base station (380) via a UAI message including a first parameter and / or a third parameter. According to an embodiment, the electronic device (301) may transmit a restriction request for the number of MIMO layers for the first service to the first base station (380) via a UAI message including a second parameter, or transmit a restriction request for the total number of CCs for the first service to the first base station (380) via a UAI message including a fourth parameter.

[0116] The embodiments described through FIGS. 1 to 3 can be applied to the electronic device (301) of FIG. 4.

[0117]

[0118] FIG. 5 is a diagram illustrating an example of the operation of an electronic device in the connection state of a first SIM and the idle state of a second SIM among a plurality of SIMs of an electronic device according to one embodiment.

[0119] Referring to FIG. 5, an electronic device (501) according to one embodiment (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, or electronic device (301) of FIG. 3) may include a first SIM (510) (e.g., first SIM (310) of FIG. 3) and a second SIM (520) (e.g., second SIM (320) of FIG. 3).

[0120] According to one embodiment, the first SIM (510) may be in a connected state (e.g., RRC connected state) with the first base station (580) (e.g., the first base station (580) of FIG. 3). In the connected state of the first SIM (510), the electronic device (501) may perform or provide the first service (e.g., call service, URLLC service, or Internet PDN service) by connecting to the first communication network.

[0121] According to one embodiment, the second SIM (520) may be in an idle state (e.g., RRC idle state). The idle state of the second SIM (520) may indicate, for example, a state in which the electronic device (501) has not formed an RRC connection through the second SIM (520).

[0122] According to one embodiment, the electronic device (501) can perform cell selection (or cell reselection) through the second SIM (520) in an idle state. If the priority of the first service is high (or if the priority of the first service corresponds to the highest priority), the electronic device (501) can attempt to camp on with the highest priority to the first cell, which is capable of limiting the capabilities of the electronic device (501) without affecting (e.g., interfering with) the first service. In an existing multi-SIM terminal, a service (e.g., a call service or a URLLC service) performed through one SIM (e.g., the first SIM (510)) may be affected by the serving cell of the other SIM (e.g., the second SIM (520)) in an idle state. For example, a call drop may occur or a delay in the URLLC service may occur. In one embodiment, while the electronic device (501) is performing a first service with high priority (e.g., a call service or a URLLC service), if cell selection (or cell re-selection) is performed through the second SIM (520) which is idle, the first cell may attempt to camp on. Accordingly, the first service may not be affected by the serving cell of the second SIM (520) which is idle, and the electronic device (501) may perform the first service seamlessly.

[0123] Hereinafter, an example of cell selection (or cell re-selection) of an electronic device will be described with reference to FIG. 6.

[0124]

[0125] FIG. 6 is a flowchart illustrating an example of cell selection (or cell re-selection) of an electronic device according to one embodiment.

[0126] Referring to FIG. 6, in operation 611, the electronic device (501) may initiate cell selection (or cell reselection) through the idle SIM. For example, the electronic device (501) may initiate cell selection (or cell reselection) when the reception level of the serving cell of the idle SIM is below a threshold value. The conditions for initiating cell selection (or cell reselection) are not limited to the examples described above.

[0127] In operation 613, the electronic device (501) can check whether the electronic device (501) is a multi-SIM terminal. The electronic device (501) can check whether it contains another SIM (e.g., the first SIM (510) of FIG. 5) other than the idle SIM (e.g., the second SIM (520) of FIG. 5). The electronic device (501) can check that the electronic device (501) is a multi-SIM terminal if it contains the first SIM (510) as well as the second SIM (520) in an idle state.

[0128] In the case where the electronic device (501) is a multi-SIM terminal (operation 613-yes), in operation 615, the electronic device (501) can determine whether the priority of the first service performed through the first communication network corresponding to the first SIM (510) corresponds to the highest priority.

[0129] When the electronic device (501) determines that the priority of the first service corresponds to the highest priority (operation 615-yes), it can determine in operation 617 whether there is a first cell. The first cell may represent, for example, a cell capable of temporarily limiting the capabilities of the electronic device (501) without interfering with the first service of the highest priority.

[0130] For example, the electronic device (501) may receive system information from each of the cells associated with the second SIM (520) in an idle state. Some of the SIB1s of the cells may contain a parameter (e.g., musim-CapRestrictionAllowed of 3GPP TS 38.331) related to whether the cell allows a temporary restriction of the electronic device (501)'s capabilities, and the remaining SIB1s may not contain musim-CapRestrictionAllowed. Depending on the implementation, the SIB1 of each of the cells may contain musim-CapRestrictionAllowed, or the SIB1 of each of the cells may not contain musim-CapRestrictionAllowed.

[0131] The electronic device (501) can identify a first cell that supports a parameter (e.g., musim-CapRestrictionAllowed) while having a frequency band that does not interfere with the first service of the highest priority based on system information received from each of the cells.

[0132] If the electronic device (501) determines that the first cell exists (Operation 617-Yes), in Operation 619, it may attempt to camp on the first cell through the idle second SIM (520). When the electronic device (501) camps on the first cell, the frequency of the first cell may not interfere with the frequency of the first service, so the electronic device (501) can provide the first service to the user without interruption. Additionally, if the electronic device (501) is in an RRC connection state with the base station of the first cell through the second SIM (520) after camping on the first cell, it may send a request to the base station of the first cell to restrict interference cells and / or frequency bands that may interfere with the first service of highest priority via a UAI message. The base station of the first cell may allocate resources for the second service while avoiding interference cells and / or frequency bands that may interfere with the first service. Accordingly, the electronic device (801) can provide the first service of highest priority to the user without interruption even while performing the second service.

[0133] If the electronic device (501) determines that there is no first cell (operation 617-No), it may determine in operation 621 whether there is a second cell. The second cell may represent a cell that does not interfere with the first service. The second cell may represent, for example, a cell having a band that does not overlap with the frequency band of the first service, but is not limited thereto.

[0134] When the electronic device (501) determines that there is a second cell (operation 621-yes), in operation 623, it may attempt to camp on the second cell through the idle second SIM (520). When the electronic device (501) camps on the second cell, the second cell may not interfere with the first service, so the electronic device (501) can provide the first service to the user without interruption.

[0135] If the electronic device (501) determines that there is no second cell (operation 621-No), in operation 625, it may attempt to camp on the cell with the best electric field through the idle second SIM (520).

[0136] In operation 615, the electronic device (501) may determine that the priority of the first service does not correspond to the highest priority.

[0137] If the priority of the first service does not correspond to the highest priority (Operation 615-No), in Operation 627, the electronic device (501) may attempt to camp on to a cell (e.g., a cell supporting musim-CapRestrictionAllowed) where it is possible to temporarily limit the capabilities of the electronic device (501) through the idle second SIM (520). If the electronic device (501) is performing a first service with a lower priority, it may attempt to camp on to a cell where it is possible to temporarily limit the capabilities of the electronic device (501) through the idle second SIM (520). If there is no cell where it is possible to temporarily limit the capabilities of the electronic device (501), the electronic device (501) may attempt to camp on to the cell with the best electric field.

[0138] In operation 613, the electronic device (501) may determine that the electronic device (501) is not a multi-SIM terminal. If the electronic device (501) is not a multi-SIM terminal (operation 613-No), in operation 629, the electronic device (501) may attempt to camp on to a cell that satisfies a specified condition (e.g., the cell with the best electric field).

[0139] According to one embodiment, the electronic device (501) may record in the cell list whether each of the cells in the stored cell list is capable of temporarily limiting the capabilities of the electronic device (501). The electronic device (501) may record in the cell list whether each of the cells in the stored cell list supports a parameter (e.g., musim-CapRestrictionAllowed).

[0140] The embodiments described through FIGS. 1 to 5 can be applied to the electronic device (501) described through FIG. 6.

[0141]

[0142] FIG. 7 is a flowchart illustrating a method for an electronic device to transmit a capability limit request according to one embodiment.

[0143] The operations (711 to 719) of FIG. 7 can be performed by an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (201) of FIG. 2, the electronic device (301) of FIG. 3, or the electronic device (501) of FIG. 5).

[0144] In operation 711, the electronic device may perform a first service (e.g., a call service or a URLLC service) through a first communication network corresponding to a first SIM (e.g., the first SIM (310) of FIG. 3 or the first SIM (510) of FIG. 5). The electronic device may perform the first service by connecting to the first communication network.

[0145] In operation 713, the electronic device may initiate cell selection (or cell re-selection) through the idle second SIM (e.g., the second SIM (320) of FIG. 3 or the second SIM (520) of FIG. 5). For example, the electronic device may initiate cell selection (or cell re-selection) when the reception level of the serving cell of the second SIM is below a threshold value.

[0146] In operation 715, the electronic device may camp on a first cell where it is possible to limit the capabilities of the electronic device without interfering with the first service being performed. For example, the electronic device may identify the first cell using system information of each of the cells associated with the second SIM and camp on the first cell.

[0147] In operation 717, after camping on to the first cell, the electronic device can form an RRC connection with the base station of the second SIM (e.g., the second base station (390) of FIG. 3) and perform the second service through the second communication network corresponding to the second SIM. For example, after camping on to the first cell, the electronic device can receive a paging message (e.g., a paging message regarding the second service) from the base station corresponding to the first cell (e.g., the second base station (390)), and after receiving the paging message, it can form an RRC connection with the base station corresponding to the first cell (e.g., the second base station (390)). The electronic device can perform the second service by connecting to the second communication network corresponding to the second SIM.

[0148] In operation 719, if the electronic device determines that the priority of a second service performed through a second communication network corresponding to the second SIM is lower than the priority of the first service and that the second service may interfere with the first service, it may transmit a restriction request for at least one of the interfering cells or frequency bands that may interfere with the first service to the base station of the second SIM. For example, the electronic device may determine that the second service may interfere with the first service if it identifies the first interfering cell and / or the first frequency band when the electronic device is in a stationary state. The electronic device may determine that the second service may interfere with the first service if it identifies the second interfering cell and / or the second frequency band when the electronic device is in a moving state.

[0149] The embodiments described through FIGS. 1 to 6 can be applied to the electronic device of FIG. 7.

[0150]

[0151] FIG. 8 is a block diagram illustrating an example of the configuration of an electronic device according to one embodiment.

[0152] Referring to FIG. 8, an electronic device (801) according to one embodiment (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, electronic device (301) of FIG. 3, or electronic device (501) of FIG. 5) may include a first SIM (810) (e.g., first SIM (310) of FIG. 3 or first SIM (510) of FIG. 5), a second SIM (820) (e.g., second SIM (320) of FIG. 3 or second SIM (520) of FIG. 5), at least one processor (830) (e.g., processor (120) of FIG. 1 or processor (210) of FIG. 2), and a memory (840) (e.g., memory (130) of FIG. 1).

[0153] The processor (830) may include processing circuitry.

[0154] According to one embodiment, the first SIM (810) and the second SIM (820) may be in a connected state (e.g., an RRC connected state). In the connected state of the first SIM (810), the electronic device (801) may perform a first service (e.g., a call service, a URLLC service, or an Internet PDN service) through a first communication network (e.g., a first communication network corresponding to the first SIM (810) or a first communication network to which the first SIM (810) is subscribed). In the connected state of the second SIM (820), the electronic device (801) may perform a second service (e.g., a call service, a URLLC service, or an Internet PDN service) through a second communication network (e.g., a second communication network corresponding to the second SIM (820) or a second communication network to which the second SIM (820) is subscribed).

[0155] According to one embodiment, in a connection state between the first SIM (810) and the second SIM (820), the electronic device (801) (e.g., processor (830)) can compare the priority of the first service and the priority of the second service.

[0156] According to one embodiment, the priority of the first service may be higher than the priority of the second service. In this case, the electronic device (801) (e.g., processor (830)) may identify at least one of the interference cells or frequency bands that interfere with the first service. The electronic device (801) (e.g., processor (830)) may transmit a restriction request for at least one of the identified interference cells (e.g., identified first interference cell or identified second interference cell) or identified frequency bands (e.g., identified first frequency band or identified second frequency band) to the base station of the second SIM (820) (e.g., the second base station (390) of FIG. 3).

[0157] According to one embodiment, an electronic device (801) (e.g., a processor (830)) can determine whether the electronic device (801) is in a stationary state. For example, the electronic device (801) (e.g., a processor (830)) can determine whether the electronic device (801) is in a stationary state by using the sensing value of the accelerometer sensor and / or the sensing value of the gyroscope sensor of the electronic device (801).

[0158] According to one embodiment, an electronic device (801) (e.g., processor (830)) may identify at least one of a first interference cell or a first frequency band when it determines that the electronic device (801) is in a stationary state. The electronic device (801) (e.g., processor (830)) may transmit a restriction request for the identified first interference cell and / or the identified first frequency band to the base station of the second SIM (820). The electronic device (801) (e.g., processor (830)) may transmit a UAI message containing the identified first interference cell and / or the identified first frequency band to the base station of the second SIM (820) so that the base station of the second SIM (820) may reallocate wireless resources for the second service excluding the identified first interference cell and / or the identified first frequency band.

[0159] According to one embodiment, an electronic device (801) (e.g., processor (830)) may identify at least one of a second interference cell or a second frequency band when it is determined that the electronic device (801) is not in a stationary state (or is in a moving state). The electronic device (801) (e.g., processor (830)) may transmit a restriction request for the identified second interference cell and / or the identified second frequency band to the base station of the second SIM (820). The electronic device (801) (e.g., processor (830)) may transmit a UAI message containing the identified second interference cell and / or the identified second frequency band to the base station of the second SIM (820) so that the base station of the second SIM (820) may reallocate wireless resources for the second service excluding the identified second interference cell and / or the identified second frequency band.

[0160] According to one embodiment, the priority of the first service and the priority of the second service may be the same. In this case, the electronic device (801) (e.g., processor (830)) may identify at least one of the interference cell or frequency band that interferes with the service performed first among the first service and the second service, and may transmit a restriction request for the identified interference cell and / or identified frequency band to the base station of the service performed later.

[0161] According to one embodiment, the first SIM (810) may be in a connected state and the second SIM (820) may be in an idle state (e.g., RRC idle state). In the case where the first SIM (810) is in a connected state and the second SIM (820) is in an idle state, the electronic device (801) (e.g., processor (830)) may determine if the first cell is among the cells associated with the second SIM (820) in the idle state if the priority of the first service corresponds to the highest priority.

[0162] For example, while performing the first service, the electronic device (801) (e.g., processor (830)) may perform cell selection (or cell re-selection) through the second SIM (820) in an idle state. The electronic device (801) (e.g., processor (830)) may determine if the first cell is among the cells associated with the second SIM (820) if the priority of the first service corresponds to the highest priority. The first cell may correspond to, for example, a cell capable of limiting the ability of a multi-SIM supporting terminal (or multi-SIM terminal) without interfering with the first service.

[0163] According to one embodiment, if the electronic device (801) (e.g., processor (830)) determines that the first cell is present, it may attempt to camp on the first cell through the idle second SIM (820).

[0164] According to one embodiment, if the electronic device (801) (e.g., processor (830)) determines that the first cell is not present, it may attempt to camp on the second cell through the second SIM (820) which is idle among the cells associated with the second SIM (820). The second cell may correspond, for example, to a cell that does not interfere with the first service. If the first cell is not present and the second cell is present, the electronic device (801) (e.g., processor (830)) may camp on the second cell, thereby providing the first service to the user without interruption.

[0165] According to one embodiment, if the electronic device (801) (e.g., processor (830)) determines that there is no second cell, it may attempt to camp on the cell with the best electric field among the cells associated with the second SIM (820) through the second SIM (820) in an idle state.

[0166] According to one embodiment, in the case where the first SIM (810) is connected and the second SIM (820) is idle, the priority of the first service may not correspond to the highest priority. In this case, the electronic device (801) (e.g., processor (830)) may attempt to camp on a cell among the cells associated with the second SIM (820) that is capable of limiting the ability of the terminal to support multi-SIM.

[0167] The memory (840) can store instructions that can be executed by the processor (830). When the stored instructions are executed by the processor (830), the electronic device (801) can perform operations of the electronic device (801).

[0168] The embodiments described through FIGS. 1 to 7 can be applied to the electronic device (801) of FIG. 8.

[0169]

[0170] FIG. 9 is a flowchart illustrating an example of an operation method of an electronic device according to one embodiment.

[0171] The operations (911, 913, 915) of FIG. 9 can be performed by an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (201) of FIG. 2, the electronic device (301) of FIG. 3, the electronic device (501) of FIG. 5, or the electronic device (801) of FIG. 8).

[0172] In operation 911, the electronic device can compare the priority of a first service performed through a first communication network corresponding to the first SIM of the electronic device (e.g., the first SIM (310) of FIG. 3, the first SIM (510) of FIG. 5, or the first SIM (810) of FIG. 8) with the priority of a second service performed through a second communication network corresponding to the second SIM of the electronic device (e.g., the second SIM (320) of FIG. 3, the second SIM (520) of FIG. 5, or the second SIM (820) of FIG. 8).

[0173] In operation 913, if the priority of the first service is higher than the priority of the second service, the electronic device can identify at least one of the interference cells or frequency bands that interfere with the first service.

[0174] In operation 915, the electronic device may transmit a restriction request for at least one of the identified interference cells or identified frequency bands to the base station of the second SIM (e.g., the second base station (390) of FIG. 3). The base station of the second SIM may reallocate wireless resources regarding the second service in accordance with the restriction request received from the electronic device.

[0175] The embodiments described through FIGS. 1 to 8 can be applied to the method of operation of the electronic device of FIG. 9.

[0176]

[0177] FIG. 10 is a flowchart illustrating an example of an operation method of an electronic device according to one embodiment.

[0178] The operations (1011, 1013, 1015) of FIG. 10 can be performed by an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (201) of FIG. 2, the electronic device (301) of FIG. 3, the electronic device (501) of FIG. 5, or the electronic device (801) of FIG. 8).

[0179] In operation 1011, the electronic device can determine whether the priority of a first service performed through a first communication network corresponding to the first SIM corresponds to the highest priority in the case where the first SIM of the electronic device (e.g., the first SIM (310) of FIG. 3, the first SIM (510) of FIG. 5, or the first SIM (810) of FIG. 8)) is in a connected state and the second SIM of the electronic device (e.g., the second SIM (320) of FIG. 3, the second SIM (520) of FIG. 5, or the second SIM (820) of FIG. 8) is in an idle state.

[0180] In operation 1013, the electronic device can determine whether there is a first cell among the cells associated with the second SIM if the priority of the first service corresponds to the highest priority.

[0181] In operation 1015, if the electronic device determines that the first cell exists, it may attempt to camp on the first cell through the second SIM. If the electronic device determines that the first cell does not exist, it may attempt to camp on the second cell, and if it determines that the second cell does not exist, it may attempt to camp on the cell with the best electric field. According to one embodiment, in the cell selection (or cell re-selection) procedure of the electronic device, the priority of the first cell may be the highest and the priority of the second cell may be the second highest. If the first cell and the second cell do not exist, the electronic device may attempt to camp on the cell with the best electric field.

[0182] The embodiments described through FIGS. 1 to 9 can be applied to the method of operation of the electronic device of FIG. 10.

[0183]

[0184] According to one embodiment, the electronic device (101, 201, 301, 501, 801) may include at least one processor (120, 210, 830) including a memory (130, 840) for storing instructions and a processing circuit.
