[0058] According to one embodiment, the processor (210) may establish a communication channel in a band to be used for wireless communication with the first cellular network (292), and support legacy network communication through the established communication channel. The first cellular network (292) may be a legacy network including, for example, a second generation (2G), 3G, 4G, or LTE (long term evolution) network. The processor (210) may establish a communication channel corresponding to a first band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second cellular network (294) (or FR (frequency range) 2 of the 5G standard (e.g., 24.25 GHz to 52.6 GHz)), and support 5G network communication through the established communication channel. The second cellular network (294) may be a 5G network as defined by 3GPP. The processor (210) can support the establishment of a communication channel corresponding to a second band (e.g., about 6 GHz or lower) (or FR1 of the 5G standard (e.g., 410 MHz to 7.125 GHz)) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0059] 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).

[0060] 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).

[0061] 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).

[0062] According to one embodiment, the electronic device (201) 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.

[0063] 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.

[0064] 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 (201) can improve the quality or speed of communication with the second cellular network (294) (e.g., 5G network).

[0065] 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 (201) (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 (201) and the outside.

[0066] 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 (201) 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 packet 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).

[0067]

[0068] FIG. 3 is a flowchart illustrating communication between an electronic device and a base station according to one embodiment.

[0069] Referring to FIG. 3, an electronic device (301) according to one embodiment (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2) may receive a capability request message (e.g., a UE capability enquiry message of 3GPP TS) from a base station (303) in operation 310. The capability request message may represent, for example, a message in which the base station (303) requests the electronic device (301) to report the capability of the electronic device (301) to the base station (303).

[0070] In response to a capability request message, the electronic device (301) may transmit capability information (e.g., UE capability information of 3GPP TS) to the base station (303) in operation 320. The capability information may include, for example, a supported list (e.g., supportedbandcombinationlist of 3GPP TS) containing band combinations supported by the electronic device (301). When the base station (303) receives the supported list from the electronic device (301), it may assign one of the band combinations in the supported list to the electronic device (301).

[0071] A band combination can represent a combination of different frequency bands. In a band combination, one of the frequency bands may correspond to an LTE band and another may correspond to an NR band. In another band combination, the frequency bands may correspond to different NR bands.

[0072] In operation 330, the electronic device (301) can receive a band combination assigned by the base station (303) from the base station (303). The electronic device (301) can receive a band combination assigned to the electronic device (301) from the base station (303) via a radio resource control (RRC) connection reconfiguration message.

[0073] The electronic device (301) can configure the software (or firmware) of the RF components of the electronic device (301) and / or configure the RF components of the electronic device (301) so as to utilize an assigned band combination. The RF components of the electronic device (301) may include, for example, one or more of an RFIC (e.g., at least one of the RFICs (222, 224, 226) of FIG. 2), an RFFE (e.g., at least one of the RFFEs (232, 234, 236) of FIG. 2), or an antenna module (e.g., at least one of the antenna modules (242, 244, 246) of FIG. 2). The electronic device (301) can configure RF paths (e.g., RF receiving paths and RF transmitting paths) according to the assigned band combination.

[0074] When the electronic device (301) completes the setup of the software (or firmware) of the RF components and / or the setup of the RF components, it can transmit a completion message (e.g., a 3GPP TS RRC connection reset completion message) to the base station (303) in operation 340.

[0075] Unlike the example illustrated in FIG. 3, the first processor (e.g., communication processor or modem) of the electronic device (301) may be rebooted due to a failure in the configuration of the assigned band combination. A reboot caused by a failure in the configuration of the assigned band combination may be referred to as a "band combination crash." A band combination crash may occur in the first processor of the electronic device (301) due to a failure in the configuration of the assigned band combination. For example, in a specific region and / or a specific operator's network, a band combination crash may occur repeatedly in the first processor of the electronic device (301). If such a crash occurs repeatedly, the electronic device (301) may fail to connect to the base station (303), and the user may experience inconvenience in using seamless services. Additionally, inefficiency in resource usage may occur in the base station (303) due to unnecessary resource allocation.

[0076] As will be explained in detail below, according to one embodiment, if a collision occurs due to a band combination, the electronic device (301) may exclude the band combination that caused the collision from the support list of the electronic device (301). The base station (303) may not assign the band combination that caused the collision to the electronic device (301). The electronic device (301) may avoid (or temporarily resolve) the collision due to a band combination without updating the software (or firmware) of the RF components.

[0077]

[0078] FIG. 4 is a diagram illustrating an example of the operation of a server according to one embodiment.

[0079] Referring to FIG. 4, a server (430) according to one embodiment (e.g., server (108) of FIG. 1) can communicate with each of a plurality of electronic devices (401-1 to 401-n).

[0080] According to one embodiment, each of the electronic devices (401-1 to 401-n) may have a service application stored therein that can perform a wireless communication connection with the server (430) and transmit a collision message to the server (430).

[0081] The electronic device (401-1) can execute a service application and can connect to the server (430) through the executed service application. If a collision occurs due to band combination 1, the electronic device (401-1) can send a collision message (or minidump) containing band combination 1 to the server (430) through the executed service application.

[0082] The electronic device (401-2) can execute a service application and can connect to the server (430) through the executed service application. If a collision occurs due to band combination 4, the electronic device (401-2) can send a collision message (or minidump) containing band combination 4 to the server (430) through the executed service application.

[0083] The electronic device (401-3) can execute a service application and can connect to the server (430) through the executed service application. If a collision occurs due to band combination A, the electronic device (401-3) can transmit a collision message (or minidump) containing band combination A to the server (430) through the executed service application.

[0084] The electronic device (401-n) can execute a service application and can connect to the server (430) through the executed service application. If a collision occurs due to band combination B, the electronic device (401-n) can transmit a collision message (or minidump) containing band combination B to the server (430) through the executed service application.

[0085] The administrator terminal (450) can access the server (430) and analyze the collision messages uploaded to the server (430) (e.g., collision messages for each of the electronic devices (401-1 to 401-n)). If the administrator terminal (450) checks that the collision that occurred in each of the electronic devices (401-1 to 401-n) is a collision caused by a band combination, it can generate a registration list (431) including the band combination that caused the collision in each of the electronic devices (401-1 to 401-n), and can store the registration list (431) in the server (430).

[0086] Whenever the administrator terminal (450) adds a band combination to the registration list (431), the registration list (431) can be updated.

[0087]

[0088] FIGS. 5A, FIGS. 5B, and FIGS. 6 are drawings illustrating examples of the operation of an electronic device and a server when a collision occurs due to a band combination in an electronic device according to one embodiment.

[0089] Referring to FIG. 5a, an electronic device (501) according to one embodiment (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, electronic device (301) of FIG. 3) may include a first processor (510) and a second processor (520). The first processor (510) may be, for example, an auxiliary processor (123) of FIG. 1 (e.g., a communication processor), and the second processor (520) may be, for example, a main processor (121) of FIG. 1 (e.g., a central processing unit or an application processor).

[0090] According to one embodiment, a service application described through FIG. 4 may be stored in the memory of the electronic device (501) (e.g., memory (130) of FIG. 1). The second processor (520) may execute the service application. The operation of the second processor (520) described below may be performed, for example, through the service application.

[0091] In operation 541, the electronic device (501) (e.g., the first processor (510)) can detect a collision (e.g., a collision caused by band combinations). For example, if the electronic device (501) (e.g., the first processor (510)) is assigned band combination 1 by a base station (e.g., the base station (303) of FIG. 3), it can perform the configuration of the software (or firmware) of the RF components of the electronic device (501) and / or the configuration of the RF components so that band combination 1 can be used. The electronic device (501) (e.g., the first processor (510)) can detect that a collision caused by band combination 1 has occurred if the configuration of the software (or firmware) of the RF components and / or the configuration of the RF components fails and the first processor (510) is rebooted.

[0092] In operation 543, the electronic device (501) (e.g., the first processor (510)) may generate a collision message (or minidump) containing the band combination that caused the collision (e.g., band combination 1). An example of the collision message (or minidump) is illustrated in FIG. 5b. In FIG. 5b, a CA (carrier aggregation) combo may represent a band combination. The collision message (571) in FIG. 5b may include, for example, an error message (571-2) indicating that an error occurred in the band combination allocation and the band combination (571-1) that caused the collision to the first processor (510). The band combination (571-1) may include an LTE band (e.g., B1) and an NR band (e.g., N78). According to an embodiment, an electronic device (501) (e.g., a first processor (510)) can generate a hash value (572-1) of a band combination (571-1) that caused a collision in the first processor (510), and can generate a collision message (572) including an error message (572-2) indicating that an error occurred in the band combination allocation and the hash value (572-1).

[0093] In operation 545, the first processor (510) of the electronic device (501) can transmit the generated collision message to the second processor (520).

[0094] According to one embodiment, an electronic device (501) (e.g., a second processor (520)) can connect to a server (530) via a wireless communication network (e.g., WiFi). For example, the electronic device (501) (e.g., a second processor (520)) can connect to the server (530) after receiving a collision message from the first processor (510). According to an embodiment, if the electronic device (501) (e.g., a second processor (520)) is unable to connect to the server (530), it can perform the operations described through FIG. 10 (e.g., operations 1017 to 1031 of FIG. 10).

[0095] According to one embodiment, the electronic device (501) (e.g., the second processor (520)) may include the model name of the electronic device (501) in the crash message of the first processor (510).

[0096] In operation 547, the electronic device (501) (e.g., the second processor (520)) can send a collision message (e.g., a collision message including the model name of the electronic device (501) and the band combination that caused the collision) to the server (530).

[0097] When the server (530) receives a collision message from the electronic device (501), it can check in operation 549 whether the band combination within the collision message is registered. For example, the server (530) can check whether band combination 1 within the collision message received from the electronic device (501) is registered (or included) in a registration list (e.g., registration list (431) of FIG. 4).

[0098] The server (530) may terminate the operation on the electronic device (501) if the band combination in the collision message received from the electronic device (501) is not registered (operation 549-No).

[0099] If the server (530) has a band combination in a collision message received from the electronic device (501) registered (e.g., if band combination 1 in the received collision message is registered in the registration list (431)) (operation 549-e), the server (530) may transmit an exclusion list to the electronic device (501) in operation 551. The exclusion list may represent, for example, a list of band combinations that must be excluded from the band combinations (or support list) that the electronic device (501) transmits (or reports) to the base station (303). The support list may represent, for example, a list containing band combinations supported by the electronic device (501). An example of an exclusion list is illustrated in FIG. 6. In the example illustrated in FIG. 6, the exclusion list (610) may include band combination 1, band combination 4, band combination A, and band combination B. The exclusion list (610) may include version values ​​of the exclusion list (610). When the exclusion list (610) is updated by the server (530), the updated exclusion list (e.g., the updated exclusion list (810) or the updated exclusion list (820) of FIG. 8) may have an increased version value.

[0100] According to one embodiment, the exclusion list (610) may be identical to the registration list (431). Not limited thereto, the exclusion list (610) to be transmitted to the electronic device (501) may include at least some of the band combinations within the registration list (431) (e.g., band combinations within a collision message transmitted by an electronic device located in the same region or adjacent region as the region of the electronic device (501).

[0101] When the electronic device (501) (e.g., the second processor (520)) receives the exclusion list (610) from the server (530), it can transmit the exclusion list (610) to the first processor (510) in operation 553.

[0102] When an electronic device (501) (e.g., a first processor (510)) receives an exclusion list (610) from a second processor (520), it may store the exclusion list (610) in operation 555. For example, the first processor (510) may store the exclusion list (610) in memory (e.g., memory (130) of FIG. 1) (e.g., non-volatile memory (134) of FIG. 1) (e.g., an embedded file system (EFS) area of ​​memory). The memory where the exclusion list (610) is stored may be located outside or inside the first processor (510).

[0103] When the electronic device (501) (e.g., the first processor (510)) stores the exclusion list (610), it can perform a reboot of the first processor (510) in operation 557.

[0104] When the electronic device (501) (e.g., the first processor (510)) performs a reboot of the first processor (510) (or when the reboot of the first processor (510) is completed), it may modify the support list of the electronic device (501) (e.g., the support list (620) of FIG. 6) based on the exclusion list (610) in operation 559. When the electronic device (501) (e.g., the first processor (510)) receives a capability request message from the base station (303), it may transmit capability information including the modified support list to the base station (303).

[0105] An example of a support list is illustrated in FIG. 6. The support list (620) may include band combinations supported by the electronic device (501) (e.g., band combination 1, band combination 2, band combination 3, band combination 4, …, band combination n, … of FIG. 6).

[0106] In the example illustrated in FIG. 6, the electronic device (501) (e.g., the first processor (510)) may obtain an exclusion list (610) from the memory (e.g., the EFS area) of the first processor (510) after the reboot of the first processor (510) is completed. The electronic device (501) (e.g., the first processor (510)) may remove (or exclude) band combinations on the exclusion list (610) from the support list (620). If a band combination on the exclusion list (610) exists in the support list (620), the electronic device (501) (e.g., the first processor (510)) may modify the support list (620) by removing (or excluding) the band combination on the exclusion list (610) from the support list (620). For example, an electronic device (501) (e.g., a first processor (510)) may remove band combination 1 and band combination 4 from the support list (620) if band combination 1 and band combination 4 of the exclusion list (610) exist in the support list (620) and band combination A and band combination B of the exclusion list (610) do not exist in the support list (620). An electronic device (501) (e.g., a first processor (510)) may remove band combination 1, band combination 4, band combination A, and band combination B from the support list (620) if all band combinations of the exclusion list (610) exist in the support list (620).

[0107] An electronic device (501) (e.g., a first processor (510)) may receive a capability request message from a base station (303). In response to the capability request message, the electronic device (501) (e.g., a first processor (510)) may transmit capability information to the base station (303) including a modified support list (e.g., band combinations remaining in the support list (620) after band combinations on the exclusion list (610) have been removed from the support list (620)).

[0108] The base station (303) may assign one of the band combinations on the modified support list to the electronic device (501). Since the modified support list excludes band combination 1 that caused a conflict with the first processor (510), the base station (303) may not be able to assign band combination 1 to the electronic device (501). The base station (303) may, for example, assign band combination 2 on the modified support list to the electronic device (501) and transmit the assigned band combination 2 to the electronic device (501) via an RRC connection reconfiguration message.

[0109] The electronic device (501) (e.g., the first processor (510)) can perform the configuration of the software (or firmware) of the RF components and / or the configuration of the RF components so that the assigned band combination 2 can be used. After the configuration of the software (or firmware) of the RF components and / or the configuration of the RF components is successful, the electronic device (501) (e.g., the first processor (510)) can transmit a completion message (e.g., an RRC connection reconfiguration complete message) to the base station (303). Accordingly, the electronic device (501) can avoid (or temporarily resolve) the conflict caused by the band combination (e.g., band combination 1) before the updated software (or firmware) capable of resolving the conflict caused by the band combination (e.g., band combination 1) is distributed. The electronic device (501) can delete the exclusion list (610) stored in memory when the updated software (or firmware) capable of resolving the conflict caused by the band combination (e.g., band combination 1) is distributed.

[0110]

[0111] FIGS. 7 and FIGS. 8 are drawings illustrating an example of an operation in which an electronic device according to one embodiment communicates with a server to update an exclusion list.

[0112] Referring to FIG. 7, in operation 711, the electronic device (501) (e.g., the first processor (510)) can transmit the version value of the exclusion list (e.g., the exclusion list (610) of FIG. 6) to the second processor (520). In the example described through FIG. 7 and FIG. 8, the version value of the exclusion list (e.g., the exclusion list (610) of FIG. 6) may be V1.

[0113] According to one embodiment, operation 711 may be performed after the electronic device (501) performs operation 559 of FIG. 5a, but is not limited thereto.

[0114] When the electronic device (501) (e.g., the second processor (520)) receives the version value of the exclusion list (610) from the first processor (510), in operation 713, it can determine whether a set period (e.g., a period for sending a request for an updated version (or the latest version) of the exclusion list (610)) has been reached. The set period may be, for example, in days, but is not limited thereto.

[0115] If the electronic device (501) (e.g., the second processor (520)) does not reach the set period (action 713-No), it may not send a request to the server (530) for an updated version (or the latest version) of the exclusion list (610) until the set period is reached.

[0116] When the electronic device (501) (e.g., the second processor (520)) reaches a set period (e.g., operation 713), in operation 715, it may send a request to the server (530) for an updated version (or the latest version) of the exclusion list (610). For example, the electronic device (501) (e.g., the second processor (520)) may send a version value (e.g., V1) of the exclusion list (610) to the server (530) in operation 715.

[0117] When the server (530) receives a request for an updated version (or latest version) of the exclusion list (610) from the electronic device (501) (or receives a version value of the exclusion list (610)), it can check in operation 717 whether there is an updated version (or updated exclusion list) of the exclusion list (610).

[0118] If the server (530) does not have an updated version of the exclusion list (610) (or an updated exclusion list) (action 717-No), it may send a response to the electronic device (501) in action 719 indicating that there is no updated version (or latest version) of the exclusion list (610).

[0119] If the server (530) has an updated version of the exclusion list (610) (or an updated exclusion list) (action 717-e), in action 721, the server (530) may transmit the updated exclusion list (or an updated version of the exclusion list (610)) to the electronic device (501). An example of an updated exclusion list (or an updated version of the exclusion list (610)) is illustrated in FIG. 8.

[0120] According to one embodiment, the updated exclusion list (810) of FIG. 8 may correspond to a list in which band combination C is added to the exclusion list (610). A collision caused by band combination C may occur in another electronic device, and the server (530) may receive a collision message containing band combination C from the other electronic device. In this case, an administrator terminal (e.g., the administrator terminal (450) of FIG. 4) may add band combination C to the exclusion list (610). Accordingly, the updated exclusion list (810) may be stored in the server (530). The updated exclusion list (810) may have a version value (e.g., V2) that is increased by 1 from the version value (e.g., V1) of the exclusion list (610).

[0121] According to one embodiment, the updated exclusion list (820) of FIG. 8 may correspond to a list in which band combination 1 is omitted (or excluded) from the exclusion list (610). For example, the network parameter of the base station (303) may have a wrong value, and as a result, a collision caused by band combination 1 may occur in the electronic device (501). The wrong value of the network parameter of the base station (303) may be changed to a normal value. After the network parameter is changed from a wrong value to a normal value, the administrator terminal (e.g., the administrator terminal (450) of FIG. 4) may check that no more collisions caused by band combination 1 have occurred by monitoring the collision messages of the electronic devices. In this case, the administrator terminal may remove band combination 1 from the exclusion list (610). The updated exclusion list (820) may be stored in the server (530). The updated exclusion list (820) may have a version value (e.g., V2) that is 1 higher than the version value (e.g., V1) of the exclusion list (610).

[0122] When the electronic device (501) (e.g., the second processor (520)) receives an updated exclusion list (e.g., the updated exclusion list (810) or the updated exclusion list (820) of FIG. 8) from the server (530), it may transmit the updated exclusion list to the first processor (510) in operation 723.

[0123] In operation 725, when the electronic device (501) (e.g., the first processor (510)) receives an updated exclusion list from the second processor (520), it may store the updated exclusion list in memory (e.g., the EFS area).

[0124] The electronic device (501) (e.g., the first processor (510)) can store the updated exclusion list in memory (e.g., the EFS area) and then perform operation 557 of FIG. 5a (e.g., rebooting the first processor (510)).

[0125] The electronic device (501) (e.g., the first processor (510)) may perform operation 559 when performing a reboot of the first processor (510). The electronic device (501) (e.g., the first processor (510)) may modify the support list (620) of the electronic device (501) based on the updated exclusion list (810 or 820). The electronic device (501) (e.g., the first processor (510)) may remove (or exclude) band combinations on the updated exclusion list (810 or 820) from the support list (620). If band combinations on the updated exclusion list (810 or 820) exist in the support list (620), the first processor (510) may modify the support list (620) by removing (or excluding) band combinations on the updated exclusion list (810 or 820) from the support list (620).

[0126] When an electronic device (501) (e.g., a first processor (510)) receives a capability request message from a base station (303), it may transmit capability information to the base station (303) including a modified support list (e.g., band combinations remaining in the support list (620) after band combinations on the updated exclusion list (810 or 820) have been removed from the support list (620).

[0127]

[0128] FIGS. 9, FIGS. 10, and FIGS. 11 are drawings illustrating examples of the operation of an electronic device when a collision occurs due to a band combination in an electronic device according to one embodiment.

[0129] Referring to FIG. 9, an electronic device (901) according to one embodiment (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, electronic device (301) of FIG. 3, electronic device (501) described through FIG. 5a to FIG. 8) may include a first processor (910) (e.g., first processor (510)) and a second processor (920) (e.g., second processor (520)).

[0130] According to one embodiment, the second processor (920) can execute a service application (e.g., the service application described through FIG. 4). The second processor (920) can manage a monitoring list (921) and / or an exclusion list (922) through the service application. The operation of the second processor (920) described below can be performed through the service application.

[0131] According to one embodiment, the second processor (920) may include (or store) a monitoring list (921). A collision caused by at least one band combination may have occurred in the first processor (910), and the second processor (920) may generate a monitoring list (921) including the band combination that caused the collision in the first processor (910). The monitoring list (921) may represent a list related to the band combination that caused the collision in the first processor (910). In the example illustrated in FIG. 9, the monitoring list (921) may include band combination 1, band combination 2, band combination 3, band combination D, and band combination F. A collision caused by each of band combination 1, band combination 2, band combination 3, band combination D, and band combination F may have occurred in the first processor (910).

[0132] According to one embodiment, the second processor (920) may store in a buffer the number of occurrences of collisions caused by each of the band combinations in the monitoring list (921). For example, the second processor (920) may store in the buffer of the second processor (920) the number of occurrences of collisions caused by band combination 1 (e.g., 9), the number of occurrences of collisions caused by band combination 2 (e.g., 3), the number of occurrences of collisions caused by band combination 3 (e.g., 2), the number of occurrences of collisions caused by band combination D (e.g., 4), and the number of occurrences of collisions caused by band combination F (e.g., 2). The number of occurrences of collisions may represent, for example, the number of collisions that occurred during a unit of time (e.g., 24 hours).

[0133] According to one embodiment, the second processor (920) may include (or store) an exclusion list (922) (e.g., the exclusion list (1110) of FIG. 11). The exclusion list (922) may represent, for example, a list of band combinations that must be excluded from the band combinations (or support list) that the electronic device (901) transmits to a base station (e.g., the base station (303) of FIG. 3).

[0134] Referring to FIG. 10, in operation 1011, an electronic device (901) (e.g., a first processor (910)) can detect a collision (e.g., a collision caused by band combinations). For example, band combination 1 may be assigned to the electronic device (901) (e.g., a first processor (910)) by a base station (e.g., a base station (303) in FIG. 3). The electronic device (901) (e.g., a first processor (910)) can perform the configuration of the software (or firmware) of the RF components of the electronic device (901) and / or the configuration of the RF components so that the assigned band combination 1 can be used. The electronic device (901) (e.g., a first processor (910)) can detect that a collision caused by band combination 1 has occurred if the configuration of the software (or firmware) of the RF components and / or the configuration of the RF components fails and the first processor (910) is rebooted.

[0135] In operation 1013, the electronic device (901) (e.g., the first processor (910)) may generate a collision message (e.g., the collision message (571 or 572) of FIG. 5b) containing the band combination that caused the collision (e.g., band combination 1).

[0136] In operation 1015, the first processor (910) of the electronic device (901) can transmit the generated collision message to the second processor (920).

[0137] When the electronic device (901) (e.g., the second processor (920)) receives a collision message from the first processor (910), it can check in operation 1017 whether the band combination in the collision message (e.g., the collision message received from the first processor (910)) is registered (or included) in the monitoring list (921).

[0138] The electronic device (901) (e.g., the second processor (920)) may terminate the operation related to the collision of the first processor (910) if the band combination in the collision message is not registered in the monitoring list (921) (operation 1017-No).

[0139] The electronic device (901) (e.g., the second processor (920)) may increase the number of occurrences of collisions caused by the band combination (e.g., band combination 1) in the collision message in operation 1019 if the band combination (e.g., band combination 1) in the collision message is registered in the monitoring list (921) (operation 1017-e.). For example, the number of occurrences of collisions caused by band combination 1 may be 9 before the second processor (920) receives a collision message containing band combination 1 from the first processor (910). The second processor (920) may increase the number of occurrences of collisions caused by band combination 1 from 9 to 10 if the band combination (e.g., band combination 1) in the collision message is registered in the monitoring list (921).

[0140] The electronic device (901) (e.g., the second processor (920)) can determine whether the increased number of occurrences (e.g., 10) satisfies a set criterion (or is above a threshold). The set criterion may be, for example, “10 times / 24 hours”, but is not limited thereto.

[0141] The electronic device (901) (e.g., the second processor (920)) may terminate the operation related to the crash of the first processor (910) if the increased number of occurrences does not satisfy the set criteria (operation 1021-No).

[0142] The electronic device (901) (e.g., the second processor (920)) may add a band combination (e.g., band combination 1) to the exclusion list (922) in operation 1023 if the increased number of occurrences (e.g., 10) satisfies a set criterion (operation 1021-e.). The electronic device (901) (e.g., the second processor (920)) may determine that if 10 collisions caused by band combination 1 occur during a unit time (e.g., 24 hours), the number of collisions caused by band combination 1 during a unit time (e.g., 10) satisfies a set criterion (e.g., 10 times / 24 hours). The electronic device (901) (e.g., the second processor (920)) may determine that the number of collisions caused by band combination 1 during a unit time (e.g., 10) is greater than or equal to a threshold value (e.g., 10). In this case, the electronic device (901) (e.g., the second processor (920)) can update the exclusion list (922) by adding band combination 1 to the exclusion list (922). An example of the exclusion list (922) is illustrated in FIG. 11. In the example illustrated in FIG. 11, the exclusion list (922) (e.g., exclusion list (1110)) may include band combination 4 and band combination C. The electronic device (901) (e.g., the second processor (920)) can update the exclusion list (1110) by adding band combination 1 to the exclusion list (1110). The updated exclusion list (1120) may include band combination 1.

[0143] The electronic device (901) (e.g., second processor (920)) may increase the version value of the exclusion list (922) when a band combination (e.g., band combination 1) is added to the exclusion list (922) (e.g., exclusion list (1110)). For example, if the version value of the exclusion list (922) (e.g., exclusion list (1110)) is V1, the updated exclusion list (e.g., exclusion list (1120)) may have a version value (e.g., V2) that is 1 increased from the version value (V1).

[0144] The electronic device (901) (e.g., the second processor (920)) can add a band combination to the exclusion list (922) (or update the exclusion list (922)) and then transmit the exclusion list (or updated exclusion list) (e.g., the updated exclusion list (1120) of FIG. 11) to the first processor (910).

[0145] In operation 1027, the electronic device (901) (e.g., the first processor (910)) may store an exclusion list (or an updated exclusion list) (e.g., the updated exclusion list (1120) of FIG. 11) received from the second processor (920). The electronic device (901) (e.g., the first processor (910)) may store the exclusion list (e.g., the updated exclusion list (1120) of FIG. 11) received from the second processor (920) in an EFS area of ​​memory.

[0146] The electronic device (901) (e.g., the first processor (910)) can perform a reboot of the first processor (910) in operation 1029 after storing the exclusion list (e.g., the updated exclusion list (1120) of FIG. 11) received from the second processor (920).

[0147] When the electronic device (901) (e.g., the first processor (910)) performs a reboot of the first processor (910) (or when the reboot of the first processor (910) is completed), it may modify the support list of the electronic device (901) (e.g., the support list (620) of FIG. 6) based on the exclusion list (e.g., the updated exclusion list (1120) of FIG. 11) in operation 1031.

[0148] For example, an electronic device (901) (e.g., a first processor (910)) may obtain an exclusion list (1120) from memory (e.g., an EFS area) after the reboot of the first processor (910) is completed. The electronic device (901) (e.g., a first processor (910)) may remove (or exclude) band combinations on the exclusion list (1120) from the support list (620). If a band combination on the exclusion list (1120) exists in the support list (620), the electronic device (901) (e.g., a first processor (910)) may modify the support list (620) by removing (or excluding) the band combination on the exclusion list (1120) from the support list (620). For example, an electronic device (901) (e.g., a first processor (910)) may remove (or delete) band combination 1 and band combination 4 from the support list (620) if band combination 1 and band combination 4 of the exclusion list (1120) exist in the support list (620) and band combination C of the exclusion list (1120) does not exist in the support list (620). The first processor (910) may remove (or delete) band combination 1, band combination 4, and band combination C from the support list (620) if all band combinations of the exclusion list (1120) exist in the support list (620).

[0149] An electronic device (901) (e.g., a first processor (910)) may receive a capability request message from a base station (303). In response to the capability request message, the electronic device (901) (e.g., a first processor (910)) may transmit capability information to the base station (303) that includes a modified support list (e.g., band combinations remaining in the support list (620) after band combinations on the exclusion list (1120) have been removed from the support list (620). The base station (303) may assign one of the band combinations on the modified support list to the electronic device (901). Since the modified support list excludes band combination 1 that caused a conflict with the first processor (910), the base station (303) may not be able to assign band combination 1 to the electronic device (901). The base station (303) may, for example, assign band combination 2 on the modified support list to the electronic device (901) and transmit the assigned band combination 2 to the electronic device (901) via an RRC connection reconfiguration message. The electronic device (901) (e.g., the first processor (910)) may perform the configuration of the software (or firmware) of the RF components and / or the configuration of the RF components so that the assigned band combination 2 can be used. After the configuration of the software (or firmware) of the RF components and / or the configuration of the RF components is successful, the electronic device (901) (e.g., the first processor (910)) may transmit a completion message (e.g., an RRC connection reconfiguration complete message) to the base station (303). Accordingly, the electronic device (901) can resolve the avoidance (or temporary resolution) of the conflict caused by the band combination (e.g., band combination 1) through a standalone method without a server before the updated software (or firmware) capable of resolving the conflict caused by the band combination (e.g., band combination 1) is distributed.The electronic device (901) can delete the exclusion list (1120) stored in memory when updated software (or firmware) capable of resolving conflicts caused by band combinations (e.g., band combination 1) is distributed.

[0150]

[0151] FIG. 12 is a flowchart illustrating an example of an operation in which an electronic device according to one embodiment updates an exclusion list.

[0152] Referring to FIG. 12, in operation 1211, the electronic device (901) (e.g., the first processor (910)) may transmit the version value of the exclusion list stored in memory (e.g., the updated exclusion list (1120) of FIG. 11) to the second processor (920). The exclusion list (1120) may have, for example, a version value (V2).

[0153] According to one embodiment, operation 1211 may be performed after the electronic device (901) performs operation 1031 of FIG. 10, but is not limited thereto.

[0154] In operation 1213, the electronic device (901) (e.g., the second processor (920)) can check whether the received version value (e.g., V2) is different from the latest version value. The latest version value may represent, for example, the version value of the latest version exclusion list that the second processor (920) stores (or manages).

[0155] The electronic device (901) (e.g., the second processor (920)) can transmit a response to the first processor (910) in operation 1215, indicating that the exclusion list held by the first processor (910) (e.g., the updated exclusion list (1120) of FIG. 11) is the latest version, if the received version value is the same as the latest version value (operation 1213-No).

[0156] The electronic device (901) (e.g., the second processor (920)) may transmit an updated exclusion list (or the exclusion list of the latest version) to the first processor (910) in operation 1217 if the received version value is different from the latest version value (or if the received version value is smaller than the latest version value) (operation 1213-e.).

[0157] After the electronic device (901) (e.g., the first processor (910)) receives the updated exclusion list (or the latest version of the exclusion list) from the second processor (920), in operation 1219, the updated exclusion list (or the latest version of the exclusion list) can be stored in memory (e.g., the EFS area).

[0158] The electronic device (901) (e.g., the first processor (910)) can perform operations 1029 and 1031 of FIG. 10 after storing the updated exclusion list (or the latest version of the exclusion list) in memory.

[0159]

[0160] FIG. 13 is a flowchart illustrating an example of an operation in which an electronic device according to one embodiment determines band combinations to be transmitted to a base station.

[0161] Operations 1310, 1320, and 1330 of FIG. 13 may be performed by an electronic device (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, electronic device (301) of FIG. 3, electronic device (501) described through FIG. 5a to FIG. 8, or electronic device (901) described through FIG. 9 to FIG. 12).

[0162] Referring to FIG. 13, in operation 1310, the electronic device may generate a support list (e.g., the support list (620) of FIG. 6) that includes band combinations common between the first list and the second list. The first list may represent, for example, a list of band combinations that the RF components of the electronic device can support. The second list may represent, for example, a list of band combinations required by a mobile network operator.

[0163] In operation 1320, the electronic device may modify the support list (620) by removing band combinations on the exclusion list (e.g., exclusion list (610) of FIG. 6, updated exclusion list (810 or 820) of FIG. 8, exclusion list (1110) of FIG. 11, or updated exclusion list (1120) of FIG. 11) from the support list (620).

[0164] In operation 1330, when the electronic device receives a capability request message from a base station (e.g., base station (303) of FIG. 3), it can transmit a modified support list to the base station (303).

[0165] The embodiments described through FIGS. 1 to 12 can be applied to the operation of the electronic device of FIG. 13.

[0166]

[0167] FIG. 14 is a flowchart illustrating another example of an operation in which an electronic device according to one embodiment determines band combinations to be transmitted to a base station.

[0168] Operations 1410, 1420, and 1430 of FIG. 14 may be performed by an electronic device (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, electronic device (301) of FIG. 3, electronic device (501) described through FIG. 5a to FIG. 8, or electronic device (901) described through FIG. 9 to FIG. 12).

[0169] Referring to FIG. 14, in operation 1410, the electronic device can modify the first list by removing band combinations on the exclusion list (e.g., exclusion list (610) of FIG. 6, updated exclusion list (810 or 820) of FIG. 8, exclusion list (1110) of FIG. 11, or updated exclusion list (1120) of FIG. 11)) from the first list.

[0170] In operation 1420, the electronic device may generate a list (hereinafter referred to as the first transmission list) containing a common band combination between the modified first list and the second list.

[0171] In operation 1430, when the electronic device receives a capability request message from a base station (e.g., base station (303) of FIG. 3), it may transmit a generated list (e.g., a generated first transmission list) to the base station (303). The electronic device may transmit capability information including the generated first transmission list to the base station (303).

[0172] The embodiments described through FIGS. 1 to 12 can be applied to the operation of the electronic device of FIG. 14.

[0173]

[0174] FIG. 15 is a flowchart illustrating another example of an operation in which an electronic device according to one embodiment determines band combinations to be transmitted to a base station.

[0175] Operations 1510, 1520, and 1530 of FIG. 15 can be performed by an electronic device (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, electronic device (301) of FIG. 3, electronic device (501) described through FIG. 5a to 8, electronic device (901) described through FIG. 9 to 12).

[0176] Referring to FIG. 15, in operation 1510, the electronic device can modify the second list by removing band combinations on the exclusion list (e.g., exclusion list (610) of FIG. 6, updated exclusion list (810 or 820) of FIG. 8, exclusion list (1110) of FIG. 11, or updated exclusion list (1120) of FIG. 11)) from the second list.

[0177] In operation 1520, the electronic device may generate a list (hereinafter referred to as the second transmission list) containing a common band combination between the modified second list and the first list.

[0178] In operation 1530, when the electronic device receives a capability request message from a base station (e.g., base station (303) of FIG. 3), it may transmit a generated list (e.g., a generated second transmission list) to the base station. The electronic device may transmit capability information including the generated second transmission list to the base station.

[0179] The embodiments described through FIGS. 1 to 12 can be applied to the operation of the electronic device of FIG. 15.

[0180]

[0181] FIG. 16 is a block diagram illustrating an example of the configuration of an electronic device according to one embodiment.

[0182] Referring to FIG. 16, an electronic device (1601) according to one embodiment (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2, electronic device (301) of FIG. 3, electronic device (501) described through FIG. 5a to FIG. 8, electronic device (901) described through FIG. 9 to FIG. 12) may include a memory (1610) and at least one processor (1620).

[0183] At least one processor (1620) may include a processing circuit.

[0184] At least one processor (1620) may include a first processor (e.g., the first processor (510) of FIG. 5a, the first processor (910) of FIG. 9) and a second processor (e.g., the second processor (520) of FIG. 5a, the second processor (920) of FIG. 9).

[0185] The memory (1610) can store instructions. The instructions can cause the electronic device (1601) to perform operations (e.g., operations of the electronic device (1601)) when executed by the processor (1620).

[0186] According to one embodiment, an electronic device (1601) (e.g., a processor (1620)) can detect a collision caused by a first band combination (e.g., band combination 1 described through FIG. 5a).

[0187] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) can transmit a collision message including a first band combination to a server (e.g., server (530) of FIG. 5a) based on a collision caused by a first band combination.

[0188] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may receive from a server (530) an exclusion list (e.g., exclusion list (610) of FIG. 6) related to band combinations excluded from a support list (e.g., support list (620) of FIG. 6)) to be transmitted to a base station (e.g., base station (303) of FIG. 3)) in response to a transmitted collision message. The exclusion list (610) may include a first band combination.

[0189] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) can identify at least one band combination that is common between a first list of band combinations that the RF components of the electronic device (1601) can support and a second list of band combinations according to the requirements of a telecommunications carrier. The electronic device (1601) (e.g., processor (1620)) can generate a support list (620) that includes the identified band combination.

[0190] According to one embodiment, the electronic device (1601) (e.g., processor (1620)) can modify the support list (620), including band combinations supported by the electronic device (1601), based on the received exclusion list (610).

[0191] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may store an exclusion list (610) in memory (1610) (e.g., EFS area) through a first processor that has crashed. After storing the exclusion list (610), the electronic device (1601) (e.g., processor (1620)) may perform a reboot of the first processor. After obtaining the exclusion list (610) from memory (1610) through the rebooted first processor, the electronic device (1601) (e.g., processor (1620)) may modify the support list (620) based on the exclusion list (610). The electronic device (1601) (e.g., processor (1620)) may modify the support list (620) by removing band combinations on the exclusion list (610) from the support list (620).

[0192] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may transmit a modified support list to a base station (303). The modified support list may include, for example, at least one band combination remaining in the support list (620) after band combinations on the exclusion list (610) have been removed from the support list (620). After receiving a capability request message from the base station (303), the electronic device (1601) (e.g., processor (1620)) may transmit capability information including the modified support list to the base station (303).

[0193] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may send a request for an updated version of the exclusion list (610) to a server (530). In response to the request for the updated version, the electronic device (1601) (e.g., processor (1620)) may receive an updated exclusion list (e.g., the updated exclusion list (810 or 820) of FIG. 8) from the server (530). The electronic device (1601) (e.g., processor (1620)) may further modify the support list (620) based on the updated exclusion list. The electronic device (1601) (e.g., processor (1620)) may send the further modified support list to a base station (303). If a second band combination (e.g., band combination C of FIG. 8) is added to the updated exclusion list (810), the second band combination may be excluded (or removed) from the further modified support list. If the first band combination (e.g., band combination 1 of FIG. 8) is not in the updated exclusion list (820), the first band combination may be included in the further modified support list.

[0194] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may receive from the base station (303) a band combination assigned by the base station (303) among band combinations on a modified support list (or a further modified support list). The electronic device (1601) (e.g., processor (1620)) may attempt to connect to the base station (303) based on the assigned band combination.

[0195] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) can modify the support list (620) of the electronic device (1601) in a standalone manner through an exclusion list (e.g., exclusion list (1110) of FIG. 11 or an updated exclusion list (1120)).

[0196] According to one embodiment, when an electronic device (1601) (e.g., processor (1620)) detects a collision caused by a first band combination, it can check whether the first band combination is registered in the electronic device (1601) (e.g., processor (1620)). For example, when an electronic device (1601) (e.g., processor (1620)) detects a collision caused by a first band combination, it can check whether the first band combination is registered in a monitoring list (e.g., monitoring list (921) of FIG. 9).

[0197] According to one embodiment, the electronic device (1601) (e.g., processor (1620)) can increase the number of occurrences of collisions caused by the first band combination when the first band combination is registered.

[0198] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) can determine whether the increased number of occurrences satisfies a set standard (e.g., 10 times / 24 hours). An electronic device (1601) (e.g., processor (1620)) can determine whether the number of occurrences of collisions by a first band combination during a unit time has exceeded a threshold value (e.g., 10).

[0199] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may add a first band combination to an exclusion list (e.g., exclusion list (1110) of FIG. 11) when the increased number of occurrences satisfies a set criterion.

[0200] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) can modify the support list (620) based on an exclusion list (e.g., an exclusion list to which a first band combination has been added) (e.g., the updated exclusion list (1120) of FIG. 11).

[0201] According to one embodiment, an electronic device (1601) (e.g., a processor (1620)) can transmit a modified support list to a base station (303).

[0202] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may transmit a request for an updated version of an exclusion list (e.g., the updated exclusion list (1120) of FIG. 11) to an application (e.g., a service application) of the electronic device (1601). The electronic device (1601) (e.g., processor (1620)) may transmit a version value of the exclusion list (e.g., the updated exclusion list (1120) of FIG. 11) to an application (e.g., a service application).

[0203] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may obtain an updated exclusion list (or a list of the latest version) from an application (e.g., a service application) in response to a request for an updated version. Through the application (e.g., a service application), the electronic device (1601) (e.g., processor (1620)) may check whether the received version value and the latest version value of the exclusion list are different, and if the received version value and the latest version value of the exclusion list are different, it may obtain an updated exclusion list (or a list of the latest version) from the application (e.g., a service application).

[0204] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may further modify the support list (620) based on an updated exclusion list (or the latest version of the exclusion list). The electronic device (1601) (e.g., processor (1620)) may transmit the further modified support list to a base station (303). If a second band combination is added to the updated exclusion list (or the latest version of the exclusion list), the second band combination may be excluded from the further modified support list.

[0205] According to one embodiment, an electronic device (1601) (e.g., processor (1620)) may receive from the base station (303) a band combination assigned by the base station (303) among band combinations on a modified support list (or a further modified support list). The electronic device (1601) (e.g., processor (1620)) may attempt to connect to the base station (303) based on the assigned band combination.

[0206] A first abnormal state (e.g., a conflict caused by band combinations) occurring in the electronic device (1601) may prevent the user from using seamless services and may cause unnecessary resource loss of the base station. According to one embodiment, the electronic device (1601) may transmit a modified support list to the base station (303), thereby causing the base station (303) to assign one of the band combinations in the modified support list to the electronic device (1601). Accordingly, the electronic device (1601) can provide seamless services to the user even before updated software (or firmware) capable of resolving the conflict caused by band combinations is distributed, and can prevent unnecessary resource loss of the base station (303). The electronic device (1601) may delete the exclusion list (or updated exclusion list) stored in memory (1610) when the software (or firmware) of the RF components of the electronic device (1601) is updated.

[0207] According to one embodiment, at least one other abnormal state may occur in the electronic device (1601). The other abnormal state may include at least one of a second abnormal state (e.g., RLF (radio link failure)), a third abnormal state (e.g., FBRX (feedback receiver) error), or a fourth abnormal state (e.g., a defect in the RF component of the electronic device (1601) or an RF component recognition error).

[0208] For example, an electronic device (1601) is connected to a base station (303), but due to a malfunction of the software (or firmware) of the RF components and / or a failure of some RF components, the electronic device (301) may not be able to transmit or receive RF signals, and as a result, RLF may occur (repeatedly).

[0209] For example, an FBRX error may occur because the transmission power of the electronic device (1601) does not match the set transmission power of the electronic device (1601).

[0210] For example, a defect may occur in the RF component of the electronic device (1601), and as a result, an error may occur in which the electronic device (1601) fails to recognize the defective RF component.

[0211] According to one embodiment, the electronic device (1601) can modify the support list (620) by removing (or excluding) band combinations associated with other abnormal conditions that occurred (e.g., band combinations where (repeated) RLF occurred, band combinations where (repeated) FBRX errors occurred, or band combinations that cannot be used due to defects in RF components) from the support list (620), and can transmit the modified support list to the base station (303).

[0212] For example, the electronic device (1601) can transmit a band combination related to another abnormal state that has occurred to the server (530), and if the band combination related to another abnormal state that has occurred is registered, the server (530) can transmit an exclusion list containing the band combination related to the other abnormal state that has occurred to the electronic device (1601). After receiving the exclusion list containing the band combination related to the other abnormal state that has occurred, the electronic device (1601) can modify the support list (620) by removing the band combination on the exclusion list from the support list (620), and can transmit the modified support list to the base station (303). In another example, in a standalone manner, the electronic device (1601) can update the exclusion list by adding band combinations associated with other abnormal conditions that occurred to the exclusion list (e.g., exclusion list (922) of FIG. 9 or exclusion list (1110) of FIG. 11), modify the support list (620) through the updated exclusion list, and transmit the modified support list to the base station (303).

[0213] According to one embodiment, through a modified support list, the base station (303) can perform resource allocation excluding band combinations associated with other abnormal conditions that occurred in the electronic device (1601). Accordingly, the electronic device (1601) can provide services to the user by avoiding other abnormal conditions that occurred.

[0214] The embodiments described through FIGS. 1 to 15 can be applied to the electronic device (1601) of FIG. 16.

[0223] In operation 1720, the electronic device (1601) may receive an exclusion list (e.g., exclusion list (610) of FIG. 6) containing a first band combination from a server (e.g., server (503) of FIG. 5a).

The electronic device (1601) may update the exclusion list by adding the band combination associated with the other abnormal state that occurred to the exclusion list (e.g., the exclusion list (1110) of FIG. 11). The electronic device (1601) may reboot the first processor (910) after storing the updated exclusion list in memory. After rebooting the first processor (910), the electronic device (1601) may modify the support list (620) through the updated exclusion list and transmit the modified support list to the base station (303). The modified support list may not contain the band combination associated with the other abnormal state that occurred in the electronic device (1601).
