In one embodiment, the second cellular network (294) may be a 5G network defined by the 3GPP. According to one embodiment, the first communication processor (212) or the second communication processor (214) may support establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0046] In one embodiment, the first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified to be transmitted via the second cellular network (294) may be changed to be transmitted via the first cellular network (292). In this case, the first communication processor (212) can receive the transmission data from the second communication processor (214). For example, the first communication processor (212) can transmit and receive data with the second communication processor (214) via the processor-to-processor interface (213). The above interprocessor interface (213) may be implemented as, for example, a universal asynchronous receiver / transmitter (UART) (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express) interface), but there is no limitation on its type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information using, for example, a shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output intensity, and resource block (RB) allocation information, with the second communication processor (214).

[0047] Depending on the implementation, the first communication processor (212) may not be directly connected to the second communication processor (214). In this case, the first communication processor (212) may transmit and receive data with the second communication processor (214) through the processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data with the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, but there is no limitation on the type of interface.

[0049] In one embodiment, the first RFIC (222) may, upon transmission, convert a baseband signal generated by the first communication processor (212) into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in a first cellular network (292) (e.g., a legacy network). Upon reception, the RF signal may be acquired from the first network (292) (e.g., a legacy network) via an antenna (e.g., the first antenna module (242)) and preprocessed via an RFFE (e.g., the first RFFE (232)). The first RFIC (222) may convert the preprocessed RF signal into a baseband signal so that it may be processed by the first communication processor (212).

[0050] In one embodiment, the second RFIC (224) may, upon transmission, convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., about 6 GHz or less) used in the second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Sub6 RF signal may be acquired from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., the second antenna module (244)) and preprocessed via an RFFE (e.g., the second RFFE (234)). The second RFIC (224) may convert the preprocessed 5G Sub6 RF signal into a baseband signal so that the preprocessed 5G Sub6 RF signal may be processed by a corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0051] In one embodiment, the third RFIC (226) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, a 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in a second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Above6 RF signal may be acquired from the second cellular network (294) (e.g., the 5G network) via an antenna (e.g., the antenna 248) and preprocessed via the third RFFE (236). The third RFIC (226) may convert the preprocessed 5G Above6 RF signal into a baseband signal so that it may be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) may be formed as a part of the third RFIC (226).

[0052] According to one embodiment, the electronic device (101) may include a fourth RFIC (228), separately from or at least as a part of the third RFIC (226). The fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, referred to as an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then 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 from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.

[0053] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as a single chip or at least a portion of a single package. According to one embodiment, when the first RFIC (222) and the second RFIC (224) in FIG. 2A or FIG. 2B are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE (232) and the second RFFE (234) to convert a baseband signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and transmit the converted signal to one of the first RFFE (232) and the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least a portion of a single chip or a single package. According to one embodiment, at least one antenna module 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 corresponding multiple bands.

[0054] In one embodiment, the third RFIC (226) and the antenna (248) may be disposed on the same substrate to form a third antenna module (246). For example, the wireless communication module (192) or the processor (120) may be disposed on the first substrate (e.g., the main PCB). In this case, the third RFIC (226) may be disposed on a portion (e.g., the bottom surface) of a second substrate (e.g., the sub PCB) separate from the first substrate, and the antenna (248) may be disposed on another portion (e.g., the top surface) to form the third antenna module (246). By disposing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line therebetween. For example, it is possible to reduce the loss (e.g., attenuation) of signals in a high-frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communication due to the transmission line. Due to this, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., 5G network).

[0055] According to one embodiment, the antenna (248) may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. 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). Upon transmission, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device (101) via its corresponding antenna element. Upon reception, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal received from the external source via its 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 external source.

[0056] In one embodiment, the second cellular network (294) (e.g., a 5G network) may operate independently (e.g., Stand-Alone (SA)) or in conjunction with (e.g., Non-Stand Alone (NSA)) the first cellular network (292) (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). After accessing the access network of the 5G network, the electronic device (101) may access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packed core (EPC)) of the legacy network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., New Radio (NR) protocol information) may be stored in the memory (130) and accessed by other components (e.g., the processor (120), the first communication processor (212), or the second communication processor (214)).

[0057] FIG. 3 illustrates a communication system including an IMS network according to one embodiment.

[0058] According to one embodiment, the electronic device (101) may be connected to a first communication network (310) (e.g., a 5G communication network) or a second communication network (320) (e.g., an LTE communication network), either individually or simultaneously. In one embodiment, the electronic device (101) may be connected to an IMS network (330) via the first communication network (310) or may be connected to an IMS network (330) via the second communication network (320). Each of the first communication network (310) and the second communication network (320) may include a (R)AN and / or a core network. The electronic device (101) may provide a communication service (e.g., a voice call or voice call service) with an external electronic device (e.g., the electronic device (102), the electronic device (104), and / or the server (108)) based on the first communication network (310) and the second communication network (320).

[0059] According to one embodiment, the electronic device (101) can modulate or demodulate a signal for communicating with at least one communication network (e.g., a first communication network (310)) through a communication circuit (e.g., a communication module (190)). For example, the electronic device (101) can be connected to at least one communication network (e.g., a communication network) through wireless or wired communication and communicate with other electronic devices. The electronic device (101) can control communication with at least one communication network or at least one IP service network. According to one embodiment, the electronic device (101) can include hardware including at least one processor and software for controlling the same. The electronic device (101) can receive communication services through the first communication network (310), the second communication network (320) or the IMS network (330).

[0060] According to one embodiment, the first communication network (310) may include a gNB and a 5GC. The gNB may be a device (e.g., a base station) that provides a wireless interface (or wireless connection) between at least one user device and an NR network. For example, the gNB may control a wireless connection of an electronic device (101) and control wireless resources (e.g., a frequency) allocated to the wireless connection. The 5GC may manage a connection for at least one electronic device (101) connected via the gNB. For example, the 5GC may provide authentication for the electronic device (101) when the electronic device (101) connects to a 5G communication network, track or manage the mobility of the electronic device (101), and provide a communication service. The 5GC may route packets communicating between the 5G communication network and an external communication network (e.g., the Internet or an IMS network (330)). The electronic device (101) can transmit and receive RTP packets containing voice information with an external electronic device, for example, via a gNB, 5GC, and IMS network (430). A call based on a 5G communication network can be called VoNR (voice over NR).

[0061] According to one embodiment, the second communication network (320) may include an evolved node B (eNB) and an evolved packet core (EPC). The eNB may be a device (e.g., a base station) that provides a wireless interface (or wireless connection) between at least one user device and an LTE network. For example, the eNB may control a wireless connection of an electronic device (101) and control wireless resources (e.g., a frequency) allocated to the wireless connection. The EPC may manage a connection for at least one electronic device (101) connected through the eNB. For example, the EPC may provide authentication for the electronic device (101) when the electronic device (101) connects to an LTE communication network, track or manage the mobility of the electronic device (101), and provide a communication service. The EPC may include a serving gateway (S-GW) and a public data network gateway (PGW). For example, the EPC may route packets communicating with the LTE communication network and an external communication network (e.g., the Internet or an IMS network (330)), provide a firewall, or assign an address (e.g., an IP address) to at least one user device. The electronic device (101) may transmit and receive RTP packets containing voice information with an external electronic device, for example, via the eNB, the EPC, and the IMS network (430). A call based on the LTE communication network may be called VoLTE (voice over LTE).

[0062] According to one embodiment, the IMS network (330) may include entities such as a call session control function (CSCF) and an application server (AS). For example, the IMS network (330) may be an IP service network and may provide IP-based multimedia services to subscribers. The CSCF may include, for example, at least one of a proxy call session control function (P-CSCF), a serving call session control function (S-CSCF), or an interrogating call session control function (I-CSCF). For example, the CSCF may register the electronic device (101) with the IMS network (330) in response to a registration request from the electronic device (101). In addition, the CSCF may provide functions related to call connections of the IMS network (330). The AS is a device for supporting services provided through the IMS network (330) and may include, for example, a telephony application server (TAS) or a voice call continuity server (VCC Server). The TAS can provide multimedia additional services (e.g., caller ID or call connection tone) to at least one electronic device (101). The VCC Server can provide seamless handover between heterogeneous networks (e.g., CDMA networks and IMS networks) to at least one user device.

[0063] According to one embodiment, the electronic device (101) can register with the IMS network (330) via the first communication network (310) or the second communication network (320). For example, the electronic device (101) can transmit a registration request (e.g., attach) to the first communication network (310) or the second communication network (320). In response to the registration request, the first communication network (310) or the second communication network (320) can assign at least one address (e.g., an IP address) to the electronic device (101). The electronic device (101) can transmit a registration request (e.g., a session initiation protocol (SIP) register) to the IMS network (330) using the at least one address. In response to the registration request, the IMS network (330) can register the electronic device (101) with the IMS network (330) and provide a service.

[0064] FIG. 4 illustrates a flowchart for explaining an operating method of an electronic device according to one embodiment.

[0065] According to one embodiment, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 401, determine a first parameter of a received signal associated with a call (e.g., VoNR or VoLTE) based on establishing a call connection with an external electronic device (e.g., at least one of the electronic device (102), the electronic device (104), or the server (108). In one embodiment, the electronic device (101) may connect to an external communication network (e.g., the Internet and / or an IMS network (330)) via a communication network (e.g., the first communication network (310) and / or the second communication network (320)). For example, the electronic device (101) may establish a call connection with an external electronic device based on accessing an IMS network (330) via a communication circuit (e.g., a communication module (190)). The electronic device (101) may perform a call with the external electronic device based on the call connection established with the external electronic device. The electronic device (101) may receive a signal associated with the call via the communication network. The electronic device (101) may determine a first parameter of a received signal associated with the call. In one embodiment, the first parameter may include at least one of a received signal strength indicator (RSSI), a signal-to-interference plus noise ratio (SINR), or a reference signals received power (RSRP) corresponding to a signal associated with the received call, and the first parameter is not limited to the examples described above. The electronic device (101) can check the condition of the electric field of the electronic device (101) based on checking the first parameter associated with the received signal.In one embodiment, the electronic device (101) can determine that the electronic device (101) is located in a relatively strong electric field based on determining that the value of the first parameter associated with the received signal is greater than or equal to a first value (or a first threshold value). The electronic device (101) can determine that the state of the communication channel formed between the electronic device (101) and the communication network is good based on determining that the first parameter is greater than or equal to the first value. In one embodiment, the electronic device (101) can determine that the electronic device (101) is located in a relatively weak electric field based on determining that the value of the first parameter associated with the received signal is less than the first value. The electronic device (101) can determine that the state of the communication channel formed between the electronic device (101) and the communication network is poor (or bad) based on determining that the first parameter is less than the first value.

[0066] In one embodiment, the electronic device (101) may determine that there is a risk of call muting based on a timer. For example, the electronic device (101) may start a timer after transmitting uplink data (UL data) (or a transmission signal (Tx signal)) to a communication network. If the electronic device (101) does not receive a response to the transmission of the uplink data from the communication network until the timer expires, the electronic device (101) may determine that there is a risk of call muting in the ongoing call.

[0067] In one embodiment, the electronic device (101) may transmit a first record flag to the external electronic device in operation 403 based on determining that the first parameter is less than the first value. The electronic device (101) may transmit the first record flag to the external electronic device through the communication circuit (e.g., the communication module (190)) based on determining that the first parameter is less than the first value, causing the external electronic device to store the input audio. Considering that a call mute may occur during a call when the first parameter is less than the first value, the electronic device (101) may cause the external electronic device to record the input audio of the external electronic device based on transmitting the first record flag to the external electronic device. In one embodiment, the first record flag may be referred to as “record flag: enable.” In one embodiment, when the first parameter is less than the second value (or the second threshold), the risk of a call mute occurring may relatively increase. The electronic device (101) may transmit a first record flag to the external electronic device based on determining that the first parameter is greater than or equal to the second value and less than the first value. By transmitting the first record flag before the risk of call muting relatively increases, the electronic device (101) may cause the external electronic device to perform call recording before the call muting occurs. In one embodiment, a call mute may be a phenomenon in which at least a portion of the call content is lost due to poor call quality being performed by the electronic device (101). In one embodiment, the call content lost due to the call mute may be referred to as a "missing voice."

[0068] In one embodiment, the electronic device (101) may transmit a second record flag to the external electronic device through the communication circuit (e.g., the communication module (190)) based on determining that the first parameter is greater than or equal to a first value, which causes the external electronic device to stop recording the input audio. The second record flag may also be referred to as a “record flag: disable.” The electronic device (101) may cause the external electronic device to stop recording the input audio of the external electronic device, considering that the risk of a call mute occurring during a call is relatively low when the first parameter is greater than or equal to the first value. In one embodiment, the record flag (the first record flag or the second record flag) may be transmitted to the external electronic device without loss when the first parameter is greater than or equal to the first value. Those skilled in the art will readily understand that in one embodiment, the electronic device (101) may transmit the first record flag to the external electronic device based on determining that the first parameter value decreases below the first value during a call after transmitting the second record flag.

[0069] In one embodiment, the electronic device (101) may store input audio while performing the call in operation 405. In one embodiment, the input audio may include call content input to the electronic device (101). For example, the input audio may include the voice of the user (or owner) of the electronic device (101) performing the call. In one embodiment, the electronic device (101) may confirm (or recognize, acquire, or store) the voice through an input module (e.g., input module (150)), an audio module (e.g., audio module (170)), or an external electronic device connected to the electronic device (101) by wire or wirelessly. In one embodiment, the electronic device (101) may store only the voice of the user of the electronic device (101) in consideration of the privacy of other users using the call service through the external electronic device. In one embodiment, one of ordinary skill in the art will readily understand that the electronic device (101) may also store the voices of other users using the calling service based on changes in settings.

[0070] In one embodiment, the electronic device (101) may, as at least part of the operation of storing input audio while performing the call, initiate storage of the input audio based on determining that the first parameter is less than the first value. The electronic device (101) may determine that the electronic device (101) performing the call is located in a weak electric field based on the value of the first parameter. The electronic device (101) may initiate storage of the input audio based on determining that the first parameter is less than the first value, taking into account that at least a portion of a user's voice of the electronic device (101) may not be transmitted to an external electronic device.

[0071] In one embodiment, the electronic device (101) may initiate storage of input audio based on establishing a call connection with the external electronic device, at least as part of the operation of storing input audio while performing the call. The electronic device (101) may store the input audio from the time the call is initiated, depending on the settings of an application associated with the call service. Those skilled in the art will readily appreciate that the electronic device (101) may also initiate storage of input audio based on a user input that causes the external electronic device to attempt a call connection.

[0072] In one embodiment, the electronic device (101) may, based on storing input audio, in operation 407, receive a request for information included in at least one mute duration (mute period, or mute section) from an external electronic device, and determine first information. In one embodiment, the request may include information regarding a time period in which a call mute occurred. In one embodiment, the electronic device (101) may determine the first information from the stored input audio. For example, the electronic device (101) may determine first information satisfying a first condition from at least a portion of audio information corresponding to the at least one mute period in the stored input audio. The mute period may be a continuous time period in which a call mute occurs. The first condition may include that the first information is data designated as a keyword, but the first condition is not limited thereto. In one embodiment, the first information may be "meaningful information" among missing voices that were not transmitted to the external electronic device. For example, the first information may include data related to a job, a task, a project, technical issues, time, or location. Those skilled in the art will readily understand that the first information is not limited to the examples described above and may change depending on the settings of the electronic device (101). For example, a user of the electronic device (101) (e.g., A) and a user of an external electronic device (e.g., B) may exchange conversations as disclosed in while using a call service.

[0073] A: Okay, Fosamax, you take one pill on Monday "and one on Thursday."B: I got it.A: Do you use much caffeine?B: No, none.

[0074] In one embodiment, a call mute may occur when a user A of an electronic device (101) inputs "and one on Thursday" into the electronic device (101) due to a poor channel condition associated with the call. A user B of an external electronic device may only take one pill per week due to not hearing information corresponding to the mute period. In one embodiment, the electronic device (101) may transmit the missing information in the call content to the external electronic device based on identifying the first information from the stored input audio. The electronic device (101) may identify "and one on Thursday" as the first information from the stored input audio based on receiving a request for information corresponding to the mute period from the external electronic device. In one embodiment, the electronic device (101) may, based on identifying the first information, transmit a response including the first information to the external electronic device in operation 409. The electronic device (101) may transmit a response including the first information to an external electronic device via a communication circuit (e.g., a communication module (190)). In one embodiment, the electronic device (101) may transmit a response including the first information in at least one format of audio or text to the external electronic device. The electronic device (101) may transmit audio data corresponding to a time section including the first information to the external electronic device. The electronic device (101) may also transmit text data corresponding to the first information to the external electronic device. For example, the electronic device (101) may transmit the response including the first information to the external electronic device using a short message service (SMS) and / or a multimedia message service (MMS).

[0075] In one embodiment, the electronic device (101) can transmit meaningful information among the missing voices to an external electronic device based on storing input audio corresponding to the call content when the electronic device (101) is located in a relatively weak electric field.

[0076] FIG. 5A and FIG. 5B are drawings for explaining the operation of an electronic device according to one embodiment.

[0077] In one embodiment, referring to FIG. 5A, the electronic device (101) may transmit a record flag (e.g., a first record flag or a second record flag) to an external electronic device (e.g., at least one of the electronic device (102), the electronic device (104), or the server (108)) based on monitoring a value of a first parameter while performing a call. In one embodiment, referring to FIG. 5A, a graph (501) of a first parameter value over time is illustrated. The electronic device (101) may monitor the value of the first parameter based on a period T. The electronic device (101) may transmit a first record flag to the external electronic device, causing the external electronic device to store (or record) at least a portion of the call content based on determining that the value of the first parameter is less than a first threshold value (th1) at time t1. The electronic device (101) may transmit a first record flag based on confirming that the value of the first parameter is less than the first threshold value (th1), considering that the risk of call muting may increase when the value of the first parameter decreases below the second threshold value (th2). The electronic device (101) may confirm that the value of the first parameter is greater than or equal to the first threshold value (th1) at time t2 after a period T. The electronic device (101) may maintain recording of the call content based on confirming that the value of the first parameter (or the average value of the first parameter during the period T) is less than or equal to the first threshold value (th1) during the time interval from time t1 to time t2. The electronic device (101) may transmit a second record flag to the external electronic device at time t3 after a period T, causing the external electronic device to stop storing (or recording) the call content. The electronic device (101) can transmit a second record flag to the external electronic device based on determining that the value of the first parameter (or the average value of the first parameter during the period T) is greater than or equal to the first threshold value during the time period from time t2 to time t3.The electronic device (101) can control the storage (or recording) of the call contents by transmitting a record flag to an external electronic device based on monitoring the value of the first parameter (or the electric field state of the electronic device (101)).

[0078] In one embodiment, referring to FIG. 5B, the electronic device (101) can check first information corresponding to at least one mute interval. In one embodiment, the electronic device (101) can check first information corresponding to at least one mute interval from stored input audio based on receiving a request for information corresponding to at least one mute interval from an external electronic device. Referring to FIG. 5B, at least a portion (511) of a call content between a user of the electronic device (e.g., user A) and a user of the external electronic device (e.g., user B) is illustrated. The electronic device (101) can check time information of at least one mute interval included in the request. The electronic device (101) can check time information of mute interval d1 and mute interval d2. The electronic device (101) can check (or call, recognize, or read) at least a portion (511) of the call content based on the stored input audio. The electronic device (101) can identify "No. 1" corresponding to the mute section d1 as the first information among the data P1, which is data regarding an address. In one embodiment, the electronic device (101) can identify that "PVI building" corresponding to the mute section d2 was repeated in the data P2 in a time section other than the mute section. Based on the identification that "PVI building" is not a missing voice, the electronic device (101) can include only the data corresponding to "No. 1" in the response transmitted to the external electronic device.

[0079] FIG. 6 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0080] According to one embodiment, the electronic device (101) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) may, in operation 601, identify a plurality of packets received while performing a call (e.g., VoNR or VoLTE) with an external electronic device (e.g., at least one of the electronic device (102), the electronic device (104), or the server (108). In one embodiment, the electronic device (101) may connect to an external communication network (e.g., the Internet and / or an IMS network (330)) via a communication network (e.g., the first communication network (310) and / or the second communication network (320)). For example, the electronic device (101) may establish a call connection with the external electronic device based on connecting to the IMS network (330) via a communication circuit (e.g., the communication module (190)). An electronic device (101) can perform a call with an external electronic device based on a call connection established with the external electronic device. The electronic device (101) can transmit and receive signals related to the call via a communication network. In one embodiment, the electronic device (101) can transmit and receive RTP packets containing voice information to and from the external electronic device. The electronic device (101) can verify a data sequence corresponding to a plurality of packets based on verifying a sequence number included in the RTP packet.

[0083] In one embodiment, referring to , the electronic device (101) can identify a mute period based on checking packet loss of packets including audio data corresponding to "00" from packet number 1546 to packet number 1552. For example, the electronic device (101) can identify a mute period from a time corresponding to packet number 1546 to a time corresponding to packet number 1552. In one embodiment, the electronic device (101) can store input audio based on receiving a first record flag from an external electronic device while performing a call in operation 605 based on checking at least one mute period. The electronic device (101) can determine that the external electronic device is located in a relatively weak electric field based on receiving the first record flag from the external electronic device. The electronic device (101) can determine that at least some of the RTP packets transmitted to the external electronic device may be lost based on receiving the first record flag. In one embodiment, the electronic device (101) may determine that the external electronic device is storing input audio of the external electronic device based on receiving the first record flag. The electronic device (101) may store the input audio of the electronic device (101) considering that the user of the external electronic device may experience a call mute. Those skilled in the art will appreciate that in one embodiment, the electronic device (101) may initiate storage of the input audio of the electronic device (101) based on a user input that causes a call connection to be established or an attempt to establish a call connection, depending on the settings of the call application. In one embodiment, the electronic device (101) may also stop storing the input audio based on receiving a second record flag from the external electronic device.

[0084] In one embodiment, the electronic device (101) may, based on receiving a first record flag, store input audio, and, in operation 607, transmit a request for information included in at least one mute interval to an external electronic device based on the termination of the call. The electronic device (101) may identify a mute interval based on checking packet loss as shown in Table 2. The electronic device (101) may not have received information corresponding to a mute interval due to packet loss. The electronic device (101) may, based on receiving the first record flag, confirm that the external electronic device stores at least the voice of the user of the external electronic device among the call contents. The electronic device (101) may, based on the termination of the call, transmit a request for information included in the mute interval to the external electronic device.

[0085] In one embodiment, the electronic device (101) may, based on transmitting a request for information included in at least one mute interval to an external electronic device, receive a response including first information corresponding to at least one mute interval in operation 609. The electronic device (101) may receive meaningful information from the external electronic device among missing voices included in the mute interval corresponding to packet loss. The electronic device (101) may, based on receiving the first record flag, confirm that the external electronic device is storing at least a portion of the call content, and, based on confirming the packet loss, request the external electronic device for information corresponding to the mute interval. The electronic device (101) may, based on receiving the meaningful information included in the mute interval from the external electronic device, improve the quality of the call service.

[0086] FIG. 7 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0087] In one embodiment, a mobile originating (MO) device (740) (e.g., electronic device (101)) may, at operation 701, attempt to make a call to a mobile terminating (MT) device (750) (e.g., at least one of electronic device (102), electronic device (104), or server (108). While FIG. 7 assumes that the mobile originating (MO) device (740) is the electronic device (101), those skilled in the art will appreciate that the mobile terminating (MT) device (750) may also be the electronic device (101). At operation 703, the MO device (740) may transmit an Invite message (e.g., a SIP INVITE) associated with the MT device (750) to the IMS network (330). For example, the electronic device (101) may transmit the Invite message including a second record flag. For example, the IMS network (330) may, in operation 705, send an Invite message to the MT device (750). The MT device (750) may, in operation 707, accept the call from the MO device (740). The MT device (750) may, in operation 709, send a Reply message (e.g., SIP 200 OK) to the IMS network (330). The Reply message may include, for example, a second record flag. The IMS network (330) may, in operation 711, send a Reply message to the MO device (740). In one embodiment, in operation 713, a call (VoLTE call or VoNR call) between the MO device (740) and the MT device (750) may be established.

[0088] According to one embodiment, the MT device (750) may, at operation 715, determine that the network condition is deteriorated. For example, the MT device (750) may determine that the network condition is poor based on determining that the strength of the received signal associated with the call is below a threshold. The MT device (750) may, at operation 717, transmit an RTP packet to the IMS network (330). For example, the header of the RTP packet may include a first record flag. The IMS network (330) may, at operation 719, transmit the RTP packet to the MO device (740). The MO device (740) may, at operation 721, transmit a Bye message (e.g., SIP BYE) to the IMS network (330). For example, the Bye message may include information about at least one mute period corresponding to a call mute that occurred in the MO device (740). The IMS network (330) may transmit a Bye message to the MT device (750) at operation 723. The MT device (750) may transmit a 200 OK message to the IMS network (330) at operation 725. For example, the 200 OK message may include information on at least one mute interval corresponding to a call mute that occurred in the MT device (750). The IMS network (330) may transmit the 200 OK message to the MO device (740) at operation 727. The MO device (740) and the MT device (750) may terminate the call at operation 729 and check information corresponding to the received mute interval (e.g., meaningful information among missing voices). The MO device (740) may transmit a SIP message to the IMS network (330) at operation 731. For example, the SIP message may include information corresponding to a mute interval received from the MT device (750). The IMS network (330) may transmit the SIP message to the MT device (750) in operation 733.The MT device (750) may transmit a SIP message to the IMS network (330) in operation 735. For example, the SIP message may include information corresponding to a mute interval received from the MO device (740). The IMS network (330) may transmit a SIP message to the MO device (740) in operation 737. The MO device (740) and the MT device (750) may each confirm a mute interval based on the method of FIG. 7, confirm information corresponding to the received mute interval, and exchange the confirmed information.

[0089] Fig. 8 illustrates a flowchart for explaining an operating method of an electronic device according to one embodiment. In Fig. 8, descriptions overlapping with those in Fig. 7 may not be repeated.

[0090] In one embodiment, the MO device (740) and the MT device (750) may establish a call connection in operation 801. The MO device (740) and the MT device (750) may establish a call connection through an IMS network (e.g., the IMS network (330)) as described in FIG. 7, and for convenience of explanation, the description of the operation of the IMS network may not be repeated in FIG. 8. In one embodiment, the MO device (740) and the MT device (750) may record and store input audio in operations 803 and 805, respectively. The MO device (740) and the MT device (750) may start (or initiate) recording of audio based on establishing a call. In one embodiment, the MO device (740) and the MT device (750) may confirm the occurrence of a call mute in operations 807 and 809, respectively. For example, the MO device (740) and the MT device (750) can confirm the occurrence of a call mute based on confirming packet loss among the received multiple RTP packets, and can confirm a mute section corresponding to the call mute. The MO device (740) and the MT device (750) can terminate the call in operation 811. The MO device (740) and the MT device (750) can exchange the confirmed mute section in operation 813. The MO device (740) and the MT device (750) can confirm information corresponding to the received mute section in operations 815 and 817. The MO device (740) and the MT device (750) can exchange the confirmed information corresponding to the mute section in operation 819.

[0092] According to one embodiment, an electronic device (e.g., electronic device (101)) may, in operation 901, determine a first parameter of a received signal associated with a call based on establishing a call connection with an external electronic device (e.g., at least one of electronic device (102), electronic device (104), or server (108)). In one embodiment, the external electronic device may be an MT device (e.g., MT device (750)) providing an automatic response service. In operation 903, the electronic device (101) may determine whether the first parameter of the received signal is less than a first value. Based on determining that the first parameter of the received signal is less than the first value, the electronic device (101) may determine that a network condition is poor. Based on determining that the first parameter of the received signal is greater than or equal to the first value (operation 903 - No), the electronic device (101) may determine whether a call mute occurs while performing the call in operation 905. The electronic device (101) can determine that a call mute has occurred, for example, based on whether packet loss has occurred among received packets. Based on determining that a call mute has occurred (Operation 905 - Yes), the electronic device (101) can request first information from an external electronic device in operation 907. In one embodiment, the electronic device (101) can also request the first information from the external electronic device based on determining that a first parameter is less than a first value (Operation 903 - Yes). For example, the first information may be information associated with an automatic response service via MMS and / or SMS. In response to the request, the electronic device (101) can receive the first information from the external electronic device in operation 909.In one embodiment, the electronic device (101) may request information associated with the automatic response service from the MT device (e.g., MT device (750)) based on whether the network condition is good, even when making a call with the MT device (101) associated with the automatic response service, and may receive the information.

In one embodiment, the electronic device (101) may check the text information corresponding to the input audio while making the call.

The electronic device (101) may store text information corresponding to the audio input while making the call as first text information. In one embodiment, the electronic device (101) may check whether at least one mute section occurs while making the call in operation 1003. For example, the electronic device (101) can determine whether a mute interval has occurred based on whether packet loss has occurred among the received packets. In one embodiment, the electronic device (101) can request information included in the mute interval in operation 1005 based on determining that a mute interval has occurred (operation 1003 - Yes). For example, the electronic device (101) can request a text file corresponding to the mute interval from an external electronic device. In one embodiment, the electronic device (101) can change the first text information based on receiving the second text information corresponding to the mute interval in operation 1007.
