Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation application of International Application No. PCT/KR2022/017170, filed on Nov. 3, 2022, which claims priority to Korean Patent Application 10-2021-0158630, filed on Nov. 17, 2021, and Korean Patent Application 10-2021-0188452, filed on Dec. 27, 2021, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties. 
    
    
     BACKGROUND 
     1. Field 
     The disclosure relates to an electronic device, and, more particularly, to performing a scan of a link generated between an electronic device and an external electronic device. 
     2. Description of Related Art 
     With the spread of various related electronic devices, speed improvement for wireless communication that may be used by the related electronic devices has been implemented. Among wireless communications supported by the related electronic devices, Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless local area network (WLAN) (e.g., Wireless Fidelity (Wi-Fi)) is a standard for implementing high-speed wireless connections on various electronic devices. The first implemented Wi-Fi could support a transmission rate of up to 1 to 9 Mbps, and Wi-Fi  6  technology (e.g., IEEE 802.11 ax) may support a transmission rate of up to about 10 Gbps. 
     The related electronic devices may support various services (e.g., ultra-high definition (UHD) video streaming services, augmented reality (AR) services, virtual reality (VR) services, and mixed reality (MR) services) using relatively large amounts of data, transmitted through wireless communication networks that support high transmission rates, and in addition, may support various other services. 
     In the IEEE 802.11 WLAN standard, a technology supporting a multi-link operation (MLO) is planned to be introduced in order to improve data transmission/reception speed and reduce delay time. A related electronic device supporting MLO may transmit and/or receive data through a plurality of links, and thus it is expected that a relatively high transmission rate and a low delay time may be realized. 
     In order to perform short-range wireless communication, the related electronic device may perform a scan operation to find an external electronic device (e.g., an access point) that transmits a signal (e.g., a beacon message or a probe response message) including information related to short-range wireless communication. In order to perform a scan operation, the related electronic device may perform an operation for receiving a signal of a frequency band corresponding to a specific channel. 
     The related art electronic device may perform a scan operation for the specific link in the process of transmitting and/or receiving data through the specific link. The related electronic device may be unable to transmit and/or receive data through a specific link while scanning is in progress. 
     Furthermore, in the related art electronic device, as the magnitude of a frequency band in which the scan is performed increases, the likelihood of a situation in which data transmission and/or reception is impossible due to time requirements may increase. For example, when the number of channels supported in short-range wireless communication through the 2.4 GHz band is 13 and the time required for the related electronic device to scan one channel is 80 milliseconds (msec), the related electronic device may take 1.04 sec (e.g., 80 msec×13) to scan the link of short-range wireless communication through the 2.4 GHz band. As another example, when the number of channels supported by short-range wireless communication through the 6 GHz band is 60 and the time required for the related art electronic device to scan one channel is 80 msec, the electronic device may take 4.8 sec (e.g., 80 ms×60) to scan the link of short-range wireless communication through the 6 GHz band. As the time for the related art electronic device to scan the link of short-range wireless communication increases, the time during which data transmission and/or reception cannot be performed through the link being scanned may increase, and the quality of short-range wireless communication provided through the link being scanned may be reduced.

     At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)). 
     According to an embodiment, commands or data may be transmitted or received between the electronic device  101  and the external electronic device  104  via the server  108  coupled with the second network  199 . Each of the electronic devices  102  or  104  may be a device of a same type as, or a different type, from the electronic device  101 . According to an embodiment, all or some of operations to be executed at the electronic device  101  may be executed at one or more of the external electronic devices  102 ,  104 , or  108 . For example, if the electronic device  101  should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device  101 , instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device  101 .

According to an embodiment, the electronic device  310  may perform wireless communication with the external electronic device  320  through short-range wireless communication. The wireless communication may refer to various communication methods that both the electronic device  310  and/or the external electronic device  320  may support. For example, the wireless communication may be Wi-Fi. The external electronic device  320  may serve as a base station that provides the wireless communication to at least one electronic device  310  located within a communication radius of the WLAN system  300 . For example, the external electronic device  320  may include an AP of IEEE 802.11. The electronic device  310  may include an IEEE 802.11 STA. 
     According to various embodiments of the present disclosure, the electronic device  310  and/or the external electronic device  320  may support MLO. The MLO may be an operation mode for transmitting and/or receiving data through a plurality of links (e.g., the first link  331  and the second link  332 ). The MLO may be an operation mode to be introduced in IEEE 802.11be, and may be an operation mode for transmitting and/or receiving data through a plurality of links, based on a plurality of bands or channels. 
     According to various embodiments of the present disclosure, the electronic device  310  may include a plurality of communication circuits (e.g., a first communication circuit  311  and/or a second communication circuit  312 ) to support the MLO. The first communication circuit  311  may transmit data to the external electronic device  320  through the first link  331 , or may receive data transmitted by the external electronic device  320  through the first link  331 .

     According to various embodiments of the present disclosure, the frequency band of the first link  331  and the frequency band of the second link  333  may be different from each other. For example, the frequency band of the first link  331  may be 2.5 GHz, and the frequency band of the second link  332  may be 5 GHz. 
     According to various embodiments of the present disclosure, the electronic device  310  may not sufficiently secure the space  351  between the first antenna  313  and the second antenna  314  due to implementation reasons. According to an embodiment, when the space  351  between the first antenna  313  and the second antenna  314  is not sufficiently secured, a signal output from the first antenna  313  and a signal received through the second antenna  314  may interfere with each other. For example, the second antenna  314  may receive a signal in which a signal received through the second link  332  and a portion of a signal output by the first antenna  313  are combined, so that the quality of a signal received through the second link  332  may be degraded. 
     According to various embodiments of the present disclosure, in order to prevent a situation in which a signal output from the first antenna  313  and a signal output from the second antenna  314  may interfere with each other, the electronic device  310  may support a non-STR mode. The non-STR mode may refer to a mode in which the electronic device  310  does not receive data through the second link  332  when the electronic device  310  transmits data to the external electronic device  320  through the first link  331 .

     According to various embodiments of the present disclosure, the electronic device  310  operating in the non-STR mode may not receive data through the second link  332  when data is transmitted to the external electronic device  320  through the first link  331 . In this case, the electronic device  310  may not be able to transmit data to the external electronic device  320  through the first link  331  while the second link  332  is scanned. The scan of the link may include a series of operations of receiving a signal transmitted (and/or broadcasted) through a frequency band corresponding to a specific link (e.g., the second link  332 ), and identifying information contained in a signal (e.g., identification information of an external electronic device that transmits a signal) and signal characteristics (e.g., signal strength, signal quality). Considering that the scanning operation of the specific link includes an operation of receiving data transmitted through the specific link, the electronic device  310  may not be able to transmit data to the external electronic device  320  through the first link  331  while the second link  332  is scanned.

For example, the wireless communication may be Wi-Fi. The external electronic device  320  may serve as a base station that provides the wireless communication to at least one electronic device  310  located within a communication radius of the WLAN system  300 . For example, the external electronic device  320  may include an AP of IEEE 802.11. The electronic device  310  may include an IEEE 802.11 STA. 
     According to various embodiments of the present disclosure, the electronic device  310  and/or the external electronic device  320  may support MLO. The MLO may be an operation mode for transmitting and/or receiving data through a plurality of links (e.g., the first link  331  and the second link  332 ). The MLO may be an operation mode to be introduced in IEEE 802.11be, and may be an operation mode for transmitting and/or receiving data through a plurality of links, based on a plurality of bands or channels. 
     According to various embodiments of the present disclosure, the electronic device  310  may include a first communication circuit  311  to support an MLO. The first communication circuit  311  may transmit data to the external electronic device  320  through the first link  331 , and/or may receive data transmitted by the external electronic device  320  through the first link  331 .

     According to various embodiments of the present disclosure, the external electronic device  320  may include a plurality of communication circuits (e.g., a third communication circuit  321  and a fourth communication circuit  322 ) to support the MLO. The third communication circuit  321  may transmit data to the electronic device  310  through the first link  331 , and/or may receive data transmitted by the electronic device  310  through the first link  331 . The third communication circuit  321  may output and/or receive a signal of a frequency band corresponding to the first link  331  through the third antenna  323 . The fourth communication circuit  322  may transmit data to the electronic device  310  through the second link  332 , and/or may receive data transmitted by the electronic device  310  through the second link  332 .

     According to various embodiments of the present disclosure, the frequency band of the first link  331  and the frequency band of the second link  333  may be different from each other. For example, the frequency band of the first link  331  may be 2.5 GHz, and the frequency band of the second link  332  may be 5 GHz. 
     According to various embodiments of the present disclosure, the electronic device  310  may support an MLO using a plurality of links generated by one communication circuit (e.g., the first communication circuit  311 ) for implementation reasons. In this case, the electronic device  310  may perform an EMLSR mode in which data having a relatively small size (e.g., control data, request-to-send (RTS) frame, clear-to-send (CTS) frame, acknowledgement (ACK) message) is transmitted using a plurality of links (e.g., first link  331 , second link  332 ), but data having a relatively large size is transmitted through one link (e.g., the first link  331 ). The EMLSR mode may refer to a mode in which data having a relatively small size is transmitted and/or received using a plurality of links, and data having a relatively large size is transmitted and/or received using a single link. When data having a relatively large size is transmitted to the external electronic device  320  through the first link  331 , the electronic device  310  operating in the EMLSR mode may not be able receive data through the second link  333 . 
     According to various embodiments of the present disclosure, the electronic device  310  operating in the EMLSR mode may not receive data through the second link  332  when data is transmitted to the external electronic device  320  through the first link  331 . In this case, the electronic device  310  may not be able to transmit data to the external electronic device  320  through the first link  331  while the second link  332  is scanned. The scan of the link may include a series of operations of receiving a signal transmitted (and/or broadcasted) through a frequency band corresponding to a specific link (e.g., the second link  332 ), and identifying information included in the signal (e.g., identification information of an external electronic device transmitting the signal) and the characteristics of the signal (e.g., signal strength, signal quality). Considering that the scanning operation of the specific link includes an operation of receiving data transmitted through the specific link, the electronic device  310  may not be able to transmit data to the external electronic device  320  through the first link  331  while the second link  332  is scanned. 
       FIG.  3 D  is a diagram illustrating an electronic device scans a first link, according to an embodiment. 
     Referring to  FIG.  3 D , the electronic device (e.g., the electronic device  310  of  FIG.  3 A ) may perform a scan operation for the first link (e.g., the first link  331  of  FIG.  3 A ). 
     The scan operation for the first link  331  may include an operation of receiving and checking a signal transmitted (and/or broadcasted) through a frequency band (and/or channel) corresponding to the first link  331 . The electronic device  310  may identify a signal (e.g., a beacon message or a probe response message) received through the first link  331 , and may identify information included in the signal (e.g., identification information of an external electronic device that transmits a signal, information necessary for connection with an external electronic device) and signal characteristics (e.g., signal strength and signal quality). 
     According to an embodiment, the electronic device  310  may discover an external electronic device that may serve as an AP (e.g., the external electronic device  320  of  FIG.  3 A ) through the scan operation for the first link  331  and may perform a series of operations to perform a connection with the discovered external electronic device through short-range wireless communication. 
     According to an embodiment, the electronic device  310  may transmit the data  341 ,  343 , and  345  to the external electronic device  320  through the first link  331 , or may receive data  341 ,  343 , and  345  transmitted by the external electronic device  320 , while being connected to the external electronic device  320  through the first link  331 . 
     According to an embodiment, the electronic device  310  may scan the first link  331  while transmitting the data  341 ,  343 , and  345  through the first link  331 . The electronic device  310  may start scanning the first link  331  for various reasons (e.g., the quality of the first link  331  is reduced below a specified value, a user input requesting to perform a scan through the first link  331  is received, and/or a running application requests to perform a scan through the first link  331 ). However, the electronic device  310  may not be able to transmit the data  343  or receive the data  343  through the first link  331  while performing the scan of the first link  331 . 
     Furthermore, in the electronic device  310 , as the size of the frequency band in which the scan is performed increases, the time during which data transmission and/or reception is impossible (e.g., prevented by the scan) may increase. For example, when the number of channels supported in short-range wireless communication through a band of 2.4 GHz is 13 and the time required for the electronic device  310  to scan one channel is 80 milliseconds (msec), the electronic device  310  may take 1.04 sec (80 msec×13) to scan the link of short-range wireless communication through the 2.4 GHz band. As another example, when the number of channels supported by short-range wireless communication through the 6 GHz band is 60 and the time required for the electronic device  310  to scan one channel is 80 msec, the electronic device  310  may take 4.8 sec (80 msec×60) to scan a link of short-range wireless communication through the 6 GHz band. 
     Hereinafter, embodiments for preventing a situation in which data transmission and/or reception are interrupted are described, even when the electronic device  310  performs a scan operation for a specific link by transmitting and/or receiving data through another link while performing a scan operation for a specific link. 
       FIG.  4    is a block diagram of an electronic device, according to various embodiments of the present disclosure. 
     According to various embodiments of the present disclosure, the electronic device (e.g., the electronic device  310  of  FIG.  3   ) may include a communication circuit (e.g., the wireless communication module  192  of  FIG.  1   )  410  and a processor (e.g., the processor  120  of  FIG.  1   )  420 . 
     The communication circuit  410  may include various circuit structures used for modulation and/or demodulation of signals within the electronic device  310 . For example, the communication circuit  410  may modulate a signal of a radio frequency (RF) band to output a signal of a baseband through an antenna (not shown), and/or may demodulate an RF band signal received through an antenna into a baseband signal and transmit the demodulated signal to the processor  420 . 
     The communication circuit  410  may perform short-range wireless communication through a first frequency band (e.g., 2.4 GHz), a second frequency band (e.g., 5 GHz) that is a frequency band higher than the first frequency band, and/or a third frequency band (e.g., 6 GHz) that is a frequency band higher than the second frequency band. 
     The communication circuit  410  may transmit a plurality of packets to an external electronic device (e.g., the external electronic device  320  of  FIG.  3   ) through a first link (e.g., the first link  331  of  FIG.  3   ), and/or may receive data transmitted by the external electronic device  320  through the first link  331 . The communication circuit  410  transmits may transmit the packet to the external electronic device  320  through the second link (e.g., the second link  332  of  FIG.  3   ), and/or may receive a packet transmitted by the external electronic device  320  through the second link  332 . The communication circuit  410  may output and/or receive a signal of a frequency band corresponding to the first link  331  through an antenna (not shown), and may output or receive a signal of a frequency band corresponding to the second link  332  through an antenna (not shown). 
     The communication circuit  410  may perform an operation for receiving a signal transmitted from the external electronic device  320  based on the control of the processor  420 . The communication circuit  410  may receive a signal requesting transmission and/or reception of data through a specific channel from the processor  420 , and may control components (e.g., a low-noise amplifier, a switch, and/or a filter) of the communication circuit  410  to receive a signal through a frequency band corresponding to a specific channel. 
     According to various embodiments of the present disclosure, the electronic device  310  may support a simultaneous transmission and reception (STR) mode capable of simultaneously transmitting and/or receiving data through a plurality of links including the first link  331  and/or the second link  332 . For example, the communication circuit  410  may transmit and/or receive data to the external electronic device  320  through the second link  332  while transmitting and/or receiving data to the external electronic device  320  through the first link  331 . However, in a situation where the difference between the frequency band of the first link  331  and the frequency band of the second link  332  is less than or equal to a specified size, the communication circuit  410  may operate in a non-STR mode in order to prevent a situation in which data transmission/reception through the first link  331  and data transmission/reception through the second link  333  interfere with each other. The non-STR mode may refer to a mode in which the electronic device  310  does not receive data through the second link  332  when the electronic device  310  transmits data to the external electronic device  320  through the first link  331 . 
     The processor  420  may perform operations of receiving the data transmitted by an application processor (e.g., the processor  120  of  FIG.  1   ), and generating a packet for transmitting the received data to the external electronic device  320 . The processor  420  may be defined as a communication processor included in a communication module (e.g., the wireless communication module  192  of  FIG.  1   ). According to an embodiment, the processor  420  may perform operations of generating a packet, identifying whether at least a portion of data transmitted by the external electronic device  320  has an error, or recovering an error (e.g., hybrid auto repeat request (HARD)) when an error occurs by performing channel coding, based on the data transmitted by the application processor  120 . 
     The processor  420  may be operatively connected to the communication circuit  410  to control the operation of the communication circuit  410 . 
     The processor  420  may control the communication circuit  410  to scan at least one of the plurality of links (e.g., the first link  331  and the second link  332 ). The processor  420  may determine to perform at least one link according to various causes (e.g., the quality of a specific link is reduced below a specified value, receiving user input requesting to perform a scan through a specific link, and/or a running application requests to perform a scan through a specific link). Hereinafter, it is assumed that the link to be scanned is the first link  331  and/or the second link  332 . 
     The processor  420  may determine whether to sequentially perform the scan of the first link  331  and the second link  332  based on the characteristic of the first link  331  and/or the characteristic of the second link  332 . 
     The characteristics of the first link  331  may include characteristics of data transmitted through the first link  331 . The data transmitted through the first link  331  may include data related to a service (e.g., voice calls and/or video calls) requiring a relatively low latency and/or data related to a service (e.g., streaming service) that may be smoothly performed even with a relatively high latency. 
     The processor  420  may refer to the first mapping data including the type of data that may be transmitted or received through the first link  331  when identifying the characteristics of the first link  331 . 
     The type of data may refer to a service type (TID) as defined in IEEE 802.11. According to one embodiment, the type of data may include a first type (e.g., voice data type (VO), image data type (VI)) requiring a relatively high transmission rate or low delay rate (e.g., real-time), and/or a second type (e.g., background (BK) and/or best effort (BE)), which may be the type of data that may be performed at a relatively low transmission rate or high delay rate when compared to the first type. 
     The first mapping data may be data including the type of data that may be transmitted or received through the first link  331 . The processor  420  may determine the type of data transmitted by the application processor  120 , and determine whether to transmit the data through the first link  331  by referring to the first mapping data. 
     For example, the first mapping data may be implemented as shown in Table 1 below.

     The characteristics of the first link  331  may include information indicating whether a mode (e.g., STR) in which data transmission and/or reception is possible simultaneously with other links (e.g., the second link  332 ) except for the first link  331  is supported. 
     The characteristics of the first link  331  may include throughput of data transmitted and/or received through the first link  331 . 
     The characteristics of the second link  332  may include characteristics of data transmitted through the second link  332 . The data transmitted through the second link  332  may include data related to services that require relatively low latency (e.g., voice calls and/or video calls) and/or data related to a service (e.g., a streaming service) that may be smoothly performed even with a relatively high latency. 
     The processor  420  may refer to the second mapping data including the type of data that may be transmitted or received through the second link  332  when identifying the characteristics of the second link  332 . 
     The type of data may refer to a service type (TID) as defined in IEEE 802.11. According to an embodiment, the type of data may include a first type (e.g., audio data type (AC_VO), image data type (AC_VI)) requiring a relatively high transmission rate or low delay rate (e.g., real-time), and/or a second type (e.g., background (AC_BK) and/or best effort (AC_BE)) that may be the type of data that may be performed at a relatively low transmission rate or high delay rate, when compared to the first type. 
     The second mapping data may be data including the type of data that may be transmitted and/or received through the second link  332 . The processor  420  may determine the type of data transmitted by the application processor  120 , and may determine whether to transmit the data through the second link  332  by referring to the second mapping data. Alternatively, the processor  420  may identify the type of data transmitted by the application processor  120 , and select a link through which data is transmitted by referring to the first mapping data and the second mapping data. For example, the second mapping data may be implemented as shown in Table 2 below.

                 Types of data that may be transmitted through the second link 332

     The characteristic of the second link  332  may include information indicating whether a mode (e.g., STR mode) in which data transmission and/or reception is possible simultaneously with links (e.g., the first link  331 ) other than the second link  332  is supported. 
     The characteristics of the second link  332  may include throughput of data transmitted or received through the second link  332 . 
     Sequentially performing the scan of the first link  331  and the second link  332  may refer to performing transmission and/or reception of data through another link, while performing a scan of either the first link  331  or the second link  332 . 
     The processor  420  may identify the characteristics of the first link  331  and the second link  332 , and may determine to sequentially perform the scan of the first link  331  and the second link  332  in response to identifying that data transmitted through the first link  331  and/or the second link  332  is data related to a service (e.g., voice calls and/or video calls) for which a relatively low latency is required. Accordingly, when the electronic device  310  sequentially performs the scan of the first link  331  and the second link  332 , interruption of data transmission and/or reception may be prevented, and thus, it may be possible to provide a service requiring a low delay time smoothly. 
     The processor  420  may identify the characteristics of the first link  331  and the second link  332 , and may determine to simultaneously perform the scan of the first link  331  and the second link  332  in response to identifying that data transmitted through the first link  331  and/or the second link  332  is a service (e.g., a streaming service) that may be smoothly performed even with a relatively high delay time. By simultaneously scanning the first link  331  and the second link  332 , the electronic device  310  may reduce a time for which data transmission and/or reception is stopped (or a time required for scanning). 
     The processor  420  may identify the characteristics of the first link  331  and the second link  332 , and may identify whether simultaneous transmission and/or reception of data of the first link  331  and the second link  332  is possible. The processor  420  may determine to sequentially perform the scan of the first link  331  and the second link  332  in response to identifying that it is possible to receive (and/or transmit) data through the second link  332  while transmitting (and/or receiving) data through the first link  331 . Accordingly, when the electronic device  310  sequentially scans the first link  331  and the second link  332 , interruption of data transmission and/or reception may be prevented, so that it may be possible to provide a service requiring a low delay time smoothly. 
     The processor  420  may identify the characteristics of the first link  331  and the second link  332 , and may identify whether simultaneous transmission and/or reception of data of the first link  331  and the second link  332  is possible. The processor  420  may determine to simultaneously perform the scan of the first link  331  and the second link  332  in response to identifying that it is impossible to receive (and/or transmit) data through the second link  332  (or identifying that the STR mode cannot be performed) while transmitting (and/or receiving) data through the first link  331 . Accordingly, the electronic device  310  simultaneously scans the first link  331  and the second link  332 , thereby reducing the time during which data transmission and/or reception is stopped (or the time required for scanning). 
     The processor  420  may identify the characteristics of the first link  331  and the second link  332 , and may identify that the throughputs of the first link  331  and the second link  332  are equal to or greater than (or greater than) a specified value. The processor  420  may determine to sequentially perform the scan of the first link  331  and the second link  332  in response to the throughput of the first link  331  and the second link  332  being equal to or greater than (or greater than) the specified value. A situation in which the throughput of the first link  331  and the second link  332  is equal to or greater than (or greater than) a specified value may be a situation in which the electronic device  310  performs relatively large number of short-range wireless communication. Accordingly, when the electronic device  310  sequentially scans the first link  331  and the second link  332 , interruption of data transmission and/or reception may be prevented, accordingly, it may be possible to provide a smooth service. 
     The processor  420  may identify the characteristics of the first link  331  and the second link  332 , and may identify that the throughputs of the first link  331  and the second link  332  are equal to or less than (or less than) a specified value. The processor  420  may determine to simultaneously perform the scan of the first link  331  and the second link  332  in response to the throughput of the first link  331  and the second link  332  being equal to or less than (or less than) the specified value. Simultaneously performing the scan of the first link  331  and the second link  332  may refer to simultaneously performing the scan of the first link  331  and the second link  332 . A situation in which the throughputs of the first link  331  and the second link  332  are less than or equal to (or less than) a specified value may be a situation in which the electronic device  310  performs relatively small short-range wireless communication. Accordingly, the electronic device  310  may reduce the time (or the time required for scanning) when data transmission and/or reception is interrupted by simultaneously scanning the first link  331  and the second link  332 . 
     The processor  420  may determine whether the first link  331  and the second link  332  are sequentially scanned or concurrently (e.g., simultaneously) scanned, based on the examples described above, as well as various characteristics of the first link  331  and the second link  332 . 
     The processor  420  may stop transmitting and/or receiving data through the first link  331  before performing a scan operation for the first link  331 , and may perform at least one operation for transmitting and/or receiving data through the second link  332 , before performing a scan operation for the first link  331 , in response to sequentially performing the scan of the first link  331  and the second link  332 . 
     The processor  420  may stop transmission and/or reception of data through the first link  331 , and may modify (and/or set) the first mapping data and/or the second mapping data as a portion of at least one or more operations for performing transmission and/or reception of data through the second link  332 . The processor  420  may modify the first mapping data and/or the second mapping data so that data to be transmitted through the link to be scanned (e.g., the first link  331 ) is transmitted through another link (e.g., the second link  332 ). 
     The processor  420  may modify the first mapping data and/or the second mapping data, based on characteristics of data to be transmitted through a link to be scanned (e.g., the first link  331 ). 
     According to an embodiment, the processor  420  may identify the types of data included in the first mapping data, and may modify the second mapping data so that the second mapping data includes a data type (e.g., VO, VI) related to a service requiring a low latency (e.g., a video call and/or a voice call) among characteristics of data included in the first mapping data. 
     For example, the processor  420  may add a data type (e.g., VO) related to a service requiring low latency (e.g., voice call) among the data types (e.g., BE, BK, VO) included in the first mapping data to the second mapping data. The modified second mapping data may be as shown in Table 3 below.

     According to another embodiment, the processor  420  may identify characteristics of data included in the first mapping data, and modify the second mapping data so that the second mapping data includes types of data included in the first mapping data. 
     For example, the processor  420  may add a data type (e.g., VO) not included in the second mapping data among the data types (e.g., BE, BK, VO) included in the first mapping data to the second mapping data. 
     According to another embodiment, the processor  420  may modify the first mapping data and/or the second mapping data so that types of data included in the first mapping data and types of data included in the second mapping data are the same. In the above manner, the first mapping data and the second mapping data may include the same types of data. The processor  420  may transmit data that could have been transmitted through the first link  331  through the second link  332  while performing the scan of the first link  331 . 
     The electronic device  310  may transmit and/or receive data to the external electronic device  320  through a third link (not shown) supporting a transmission rate and/or reception rate (e.g., communication rate) relatively higher than that of the second link  332 . The processor  420  may generate and/or manage third mapping data including the type of data that may be transmitted or received through the third link. 
     The first mapping data, the second mapping data, and/or the third mapping data may be stored in a memory implemented inside or outside the processor  420  (e.g., the memory  130  of  FIG.  1   ). 
     Before performing the scan of the first link  331 , when data transmission and/or reception is possible through the third link, the processor  420  may modify (and/or set) the third mapping data to include a type of data related to a service requiring a low delay time among data types included in the first mapping data. The processor  420  may modify (and/or set) the second mapping data to include the type of data related to a service (e.g., a streaming service) that may be smoothly performed even with a relatively high latency among types of data included in the first mapping data. 
     Through the embodiments described above, while performing the scan of the first link  331 , the processor  420  may transmit data related to a service requiring a low delay time among data to be transmitted through the first link  331  to the third link, and may transmit data related to a service that may be smoothly performed, even with a relatively high delay time, to the second link  332 . 
     According to another embodiment, before performing the scan of the first link  331 , when data transmission and/or reception is possible through the third link, the processor  420  may modify (and/or set) the third mapping data to include the type of data related to a service requiring a relatively low delay time among data transmitted by the electronic device  310 . The processor  420  may modify (and/or set) the second mapping data to include the type of data related to a service (e.g., a streaming service) that may be smoothly performed even with a relatively high delay time among the types of data transmitted by the electronic device  310 . 
     Through the embodiments described above, while performing the scan of the first link  331 , the processor  420  may transmit data related to a service requiring a low delay time among data to be transmitted by the electronic device  310  to the third link, and may transmit, through the second link  332 , data related to a service that may be smoothly performed even if the electronic device  310  has a relatively high delay time among data to be transmitted. 
     The processor  420  may complete the modification of the first mapping data and/or the second mapping data, and may control the communication circuit  410  to transmit a signal instructing to stop data transmission and/or reception to the external electronic device  320  through the first link  331  before performing the scan operation for the first link  331 . 
     The short-range wireless communication defined in IEEE 802.11 may allow data transmission and/or reception to be performed after transmitting a signal to support various functions (e.g., a power management mode or an automatic power save delivery (APSD) mode) that may reduce power consumption. The processor  420  may transmit a signal instructing to stop transmitting and/or receiving data through the first link  331  using a power management mode or an APSD mode defined in short-range wireless communication. 
     A signal indicating that data to be transmitted or received by the electronic device  400  through the first link  331  does not exist may be implemented in the form of a null data packet (NDP) as defined in IEEE 802.11, and the NDP may include a field (e.g., PWR MGT) indicating whether data to be transmitted or received by the electronic device  500  exists. A value (e.g., 0) of a field indicating whether data to be transmitted or received by the electronic device  500  exists when data to be transmitted or received by the electronic device  500  exists and a value (e.g., 1) of a field indicating whether data to be transmitted or received by the electronic device  500  exists when data to be transmitted or received by the electronic device  500  does not exist may be different from each other. 
     The processor  420  may transmit and/or receive data through the second link  332  while performing a scan operation for the first link  331 . The processor  420  may select a link (e.g., the second link  332 ) to transmit data based on the modified second mapping data, and control the communication circuit  410  to transmit data through the selected link. In the above manner, the electronic device  310  may perform data transmission and/or reception through the second link  332  while performing the scan operation for the first link  331 , so that a smooth service may be provided. 
       FIG.  5    is a diagram illustrating an electronic device modifying first mapping data including the type of data to be transmitted through a first link and second mapping data including the type of data to be transmitted through a second link, in order to perform a scan of a first link, according to an embodiment. 
     Referring to  FIG.  5   , the electronic device (e.g., the electronic device  310  of  FIG.  4   ) may be connected to an external electronic device (e.g., the external electronic device  320  of  FIG.  3 A ) through a first link (e.g., the first link  331  of  FIG.  3 A ) and/or a second link (e.g., the second link  332  of  FIG.  3 A ) to transmit and/or receive data. 
     The electronic device  310  may set the first mapping data  511  including the type of data that may be transmitted or received through the first link  331 . 
     The data type may refer to a service type (TID) as defined in IEEE 802.11. According to an embodiment, the data type may include a first type (e.g., voice data type (AC_VO), image data type (AC_VI)) requiring a relatively high transmission rate or low delay rate (e.g., real-time) and/or a second type (e.g., background (AC_BK) and/or best effort (AC_BE)), which is the type of data that may be performed at a relatively low transmission rate or high delay rate compared to the first type. 
     For example, the first mapping data  511  may include a data type of BK or VI. The electronic device  310  may transmit data through the first link  331 , based on identifying that the type of data to be transmitted to the external electronic device  320  is included in the first mapping data  511 . 
     The electronic device  310  may set the second mapping data  513  including the type of data that may be transmitted or received through the second link  332 . 
     For example, the second mapping data  513  may include data types of BK, BE, and VO. The electronic device  310  may transmit data through the second link  332 , based on identifying that the type of data (e.g., VO) to be transmitted to the external electronic device  320  is included in the second mapping data  513 . 
     The electronic device  310  may control the communication circuit  410  to scan at least one of the plurality of links (e.g., the first link  331  and the second link  332 ). The electronic device  310  may determine to perform at least one link, depending on various causes (e.g., the quality of a specific link decreases below a specified value, receiving user input requesting to perform a scan through a specific link, and/or a running application requests to perform a scan through a specific link). 
     The electronic device  310  may determine to sequentially scan the first link  331  and the second link  332 , based on the characteristics of the first link  331  and/or the characteristics of the second link  332 . In  FIG.  5   , for convenience of explanation, it is assumed that the electronic device  310  scans the first link  331  first, and then scans the second link  332  after the scan of the first link  331  is completed. 
     In response to sequentially performing the scan of the first link  331  and the second link  332 , the electronic device  310  stops transmission and/or reception of data through the first link  331  before performing the scan operation for the first link  331 , and may perform at least one operation for performing transmission and/or reception of data through the second link  332 . 
     The electronic device  310  may stop transmitting and/or receiving data through the first link  331 , and may modify (and/or set) the first mapping data  511  and/or the second mapping data  513 , as a portion of at least one or more operations for performing transmission and/or reception of data through the second link  332 . The electronic device  310  may modify the first mapping data  511  and/or the second mapping data  513  so that data to be transmitted through the link to be scanned (e.g., the first link  331 ) is transmitted through another link (e.g., the second link  332 ) 
     According to an embodiment, the electronic device  310  may identify the data types (e.g., BK, VI) included in the first mapping data  511 , and may modify the second mapping data  513  such that the second mapping data  513  includes characteristics (e.g., BK, VI) of data included in the first mapping data. In the modified second mapping data  521 , a data type (e.g., VI) included in the first mapping data may be added to the data type (e.g., BK, BE, VO) included in the second mapping data  513  before modification. The first mapping data  511  may be maintained without modification. 
     The electronic device  310  may complete the modification of the first mapping data  511  and/or the second mapping data  513 , and may control the communication circuit  410  to transmit a signal  523  instructing to stop transmitting and/or receiving data through the first link  331  to the external electronic device  320  before performing the scan operation for the first link  331 .

     The electronic device  310  may scan the second link  332  after the scan of the first link  331  is completed. The electronic device  310  may stop transmitting and/or receiving data through the second link  332  before performing the scan of the second link  332 , and may perform at least one operation for transmitting and/or receiving data through the first link  331 . 
     The electronic device  310  may stop transmission and/or reception of data through the second link  332 , and may modify (and/or set) the first mapping data  511  and/or the second mapping data  513 , as a portion of at least one or more operations for performing transmission and/or reception of data through the first link  331 . The electronic device  310  may modify the first mapping data  511  and/or the second mapping data  513  so that data to be transmitted through the link to be scanned (e.g., the second link  332 ) is transmitted through another link (e.g., the first link  331 ). 
     According to an embodiment, the electronic device  310  may identify the data types (e.g., BK, BE, VI, VO) included in the modified second mapping data  521 , and may modify the first mapping data  511  to include characteristics (e.g., BE, VO) of data included in the modified second mapping data  521 . In the corrected first mapping data  531 , the data types (e.g., BE, VO) included in the first mapping data may be added at the type (e.g., BK, VI) of the data included in the first mapping data  511  before modification. The electronic device  310  may restore the existing second mapping data  513  from the modified second mapping data  521 . 
     The electronic device  310  may complete the modification of the first mapping data  511  and/or the second mapping data  513 , and may control the communication circuit  410  to transmit a signal  533  instructing to stop transmitting and/or receiving data through the second link  332  to the external electronic device  320 , before performing the scan operation for the second link  332 . 
     The electronic device  310  may perform a scan operation for the second link  332  after transmitting the signal  533 . The electronic device  310  may transmit and/or receive data through the first link  331  while performing a scan operation for the second link  332 . The electronic device  310  may transmit data through the first link  331 , based on identifying that the type of data (e.g., VI) to be transmitted to the external electronic device  320  is included in the corrected first mapping data  531 .

     The electronic device  310  may stop transmission and/or reception of data through the first link  331  and perform at least one or more operations for performing transmission and/or reception of data through the second link  332  before performing the scan operation for the first link  331 , in response to sequentially performing the scan of the first link  331  and the second link  332 . 
     The electronic device  310  may stop transmission and/or reception of data through the first link  331 , and may modify (and/or set) the first mapping data  811  and/or the second mapping data  813 , as a portion of at least one or more operations for performing transmission and/or reception of data over the second link  332 .

     Referring to  FIG.  9   , the electronic device (e.g., the electronic device  310  of  FIG.  4   ) may be connected to an external electronic device (e.g., the external electronic device  320  of  FIG.  3 A ) through a first link (e.g., first link  331  of  FIG.  3 A ), a second link (e.g., second link  332  of  FIG.  3 A ), and/or a third link  901  to transmit and/or receive data. 
     The frequency bands of the first link  331 , the second link  332 , and/or the third link  901  may be different from each other. For example, the frequency band of the third link  901  may be larger than the frequency band of the second link  332 , and the frequency band of the second link  332  may be larger than the frequency band of the first link  331 . Accordingly, the data transmission rate and/or reception rate (e.g., communication rate) of the third link  901  may be greater than the data transmission rate and/or reception rate of the second link  332 , and the data transmission rate and/or reception rate of the second link  332  may be greater than the data transmission rate and/or reception rate of the first link  331 . 
     The electronic device  310  may set the first mapping data  911  including the type of data that may be transmitted or received through the first link  331 . 
     The data type may refer to a service type (TID) as defined in IEEE 802.11. According to an embodiment, the type of data may include a first type (e.g., audio data type (AC_VO), video data type (AC_VI)) requiring a relatively high transmission rate or low delay rate (e.g., real-time performance), and/or a second type (e.g., background (AC_BK) and/or best effort (AC_BE)) that is the type of data that may be performed at a relatively low transmission rate or high delay rate compared to the first type. 
     For example, the first mapping data  911  may include data types of BK and VI. The electronic device  310  may transmit data through the first link  331 , based on confirming that the type of data to be transmitted to the external electronic device  320  is included in the first mapping data  911 . 
     The electronic device  310  may set the second mapping data  913  including the type of data that may be transmitted or received through the second link  332 . 
     For example, the second mapping data  913  may include data types of BE and VO. The electronic device  310  may transmit data through the second link  332 , based on identifying that the type of data to be transmitted to the external electronic device  320  (e.g., VO) is included in the second mapping data  913 . 
     The electronic device  310  may set the third mapping data  915  including the type of data that may be transmitted or received through the third link  901 . 
     For example, the third mapping data  915  may include data types of BK and VO. The electronic device  310  may transmit data through the third link  901 , based on confirming that the type of data (e.g., VO) to be transmitted to the external electronic device  320  is included in the third mapping data  915 . 
     The electronic device  310  may control the communication circuit  410  to perform a scan of at least one of the plurality of links (e.g., the first link  331 , the second link  332 , and/or the third link  901 ). The electronic device  310  may determine to perform at least one link according to various causes (e.g., the quality of a specific link is reduced below a specified value, receiving user input requesting to perform a scan through a specific link, and/or a running application requests to perform a scan through a specific link). 
     The electronic device  310  may determine to sequentially scan the first link  331  and the second link  332 , based on the characteristics of the first link  331 , the characteristics of the second link  332 , and/or the characteristics of the third link  901 . In  FIG.  9   , for convenience of explanation, it is assumed that the electronic device  310  first scans the first link  331 , scans the second link  332  after the scan of the first link  331  is completed, and scans the third link  901  after the scan of the second link  332  is completed. 
     In response to sequentially performing the scan of the first link  331 , the second link  332 , and/or the third link  901 , before performing the scan operation for the first link  331 , the electronic device  310  may stop transmission and/or reception of data through the first link  331 , and may perform at least one operation for transmitting and/or receiving data through the second link  332  and/or the third link  901 .

     The electronic device  310  may determine a data type to be added to the second mapping data  913  and/or the third mapping data  915 , based on the transmission rate (and/or reception rate) of the second link  332  and/or the third link  901 . 
     The electronic device  310  may modify the second mapping data  912  to add a data type requiring a low delay rate among data types included in the first mapping data  911  to the second mapping data  913 , and may modify the third mapping data  915  to add a data type requiring a lower delay rate among data types included in the first mapping data  911  to the third mapping data  915 . 
     According to an embodiment, the electronic device  310  may identify the data types (e.g., BK, VI) included in the first mapping data  911 , may modify the third mapping data  915  to include a data type (e.g., VI) related to a service requiring low latency among types of data included in the first mapping data, and may modify the second mapping data  913  to include a service-related data type (e.g., BK) that enables smooth service execution even with a relatively high delay time among the data types included in the first mapping data. 
     According to an embodiment, the electronic device  310  may modify the first mapping data  911  so as not to include the data type. The modified first mapping data  921  may not include any data type. In this case, since the electronic device  310  may not transmit and/or receive any data through the first link  331 , the electronic device  310  may not transmit a signal (e.g., signal  523  of  FIG.  5   ) instructing to stop data transmission and/or reception to the external electronic device  320  through the first link  331 . 
     The electronic device  310  may complete the modification of the first mapping data  911 , the second mapping data  913 , and/or the third mapping data  915 , and may perform a scan operation for the first link  331 . The electronic device  310  may transmit and/or receive data through the second link  332  and/or the third link  901  while performing the scan operation for the first link  331 .

     The electronic device (e.g., the electronic device  310  of  FIG.  4   ), according to various embodiments of the present disclosure, in operation  1110  may determine whether to perform the scans of the first link  331  and the second link  332  sequentially or simultaneously, based on characteristics of the first link (e.g., first link  331  in  FIG.  3 A ) and second link (e.g., second link  332  in  FIG.  3 A ). 
     The characteristics of the first link  331  may include characteristics of data transmitted through the first link  331 . The data transmitted through the first link  331  may include data related to services that require relatively low latency (e.g., voice calls and/or video calls) and/or services that may perform smoothly even with relatively high latency (e.g., streaming services). 
     When identifying the characteristics of the first link  331 , the electronic device  310  may refer to the first mapping data including the type of data that may be transmitted or received through the first link  331 . 
     The data type may refer to a service type (TID) as defined in IEEE 802.11. According to an embodiment, the data type may include a first type (e.g., voice data type (VO), image data type (VI)) requiring a relatively high transmission rate or low delay rate (e.g., real-time performance), and/or a second type (e.g., background (BK) and/or best effort (BE)) which is the type of data that may be performed at a relatively low transmission rate or high delay rate compared to the first type.

The electronic device  310  may identify the type of data transmitted by the application processor  120 , and may determine whether to transmit data through the first link  331  by referring to the first mapping data. 
     The characteristics of the first link  331  may include information indicating whether a mode (e.g., STR mode) in which data transmission and/or reception is possible simultaneously with other links (e.g., the second link  332 ) other than the first link  331  is supported.

Alternatively, the electronic device  310  may identify the type of data transmitted by the application processor  120 , and may select a link through which data is transmitted by referring to the first mapping data and the second mapping data. 
     The characteristics of the second link  332  include information indicating whether a mode (e.g., STR mode) in which data transmission and/or reception is possible simultaneously with links other than the second link  332  (e.g., the first link  331 ) is supported. 
     The characteristics of the second link  332  may include throughput of data transmitted or received through the second link  332 . 
     Sequentially performing the scan of the first link  331  and the second link  332  may refer to performing, while performing a scan of either the first link  331  or the second link  332 , transmission and/or reception of data through the other link. 
     The electronic device  310  may identify the characteristics of the first link  331  and the second link  332 , and may determine to sequentially perform the scan of the first link  331  and the second link  332 , in response to identifying that the data transmitted over the first link  331  and/or the second link  332  is data related to a service requiring relatively low latency (e.g., a voice call and/or a video call). Accordingly, when the electronic device  310  sequentially performs the scan of the first link  331  and the second link  332 , interruption of data transmission and/or reception may be prevented, so that it may be possible to provide a service requiring a low delay time smoothly. 
     The electronic device  310  may identify the characteristics of the first link  331  and the second link  332 , and may determine to simultaneously perform the scan of the first link  331  and the second link  332  in response to identifying that data transmitted through the first link  331  and/or the second link  332  is a service (e.g., a streaming service) that may be smoothly performed even with a relatively high delay time. By simultaneously scanning the first link  331  and the second link  332 , the electronic device  310  may reduce a time for which data transmission and/or reception is stopped (or a time required for scanning). 
     The electronic device  310  may identify the characteristics of the first link  331  and the second link  332 , and may identify whether simultaneous transmission and/or reception of data of the first link  331  and the second link  332  is possible.

Accordingly, when the electronic device  310  sequentially scans the first link  331  and the second link  332 , interruption of data transmission and/or reception may be prevented, so that it may be possible to provide a service requiring a low delay time smoothly. 
     The electronic device  310  may identify the characteristics of the first link  331  and the second link  332 , and identify whether simultaneous transmission and/or reception of data of the first link  331  and the second link  332  is possible. The electronic device  310  may determine to simultaneously perform the scan of the first link  331  and the second link  332  in response to identifying that it is impossible to receive (and/or transmit) data over the second link  332  while transmitting (and/or receiving) data over the first link  331  (or perform STR mode). Accordingly, the electronic device  310  may reduce the time (or the time required for scanning) when data transmission and/or reception is interrupted by simultaneously scanning the first link  331  and the second link  332 . 
     The electronic device  310  may identify the characteristics of the first link  331  and the second link  332 , and may identify that the throughput of the first link  331  and the second link  332  is equal to or greater than (or greater than) a specified value. The electronic device  310  may determine to sequentially perform the scan of the first link  331  and the second link  332  in response to the throughput of the first link  331  and the second link  332  being greater than (or greater than) the specified value. A situation in which the throughputs of the first link  331  and the second link  332  are equal to or greater than (or greater than) a specified value may be a situation in which the electronic device  310  performs relatively large number of short-range wireless communication. Accordingly, when the electronic device  310  sequentially scans the first link  331  and the second link  332 , interruption of data transmission and/or reception may be prevented, thereby enabling smooth service provision. 
     The electronic device  310  may identify the characteristics of the first link  331  and the second link  332 , and may identify that the throughputs of the first link  331  and the second link  332  are equal to or less than (or less than) a specified value. The electronic device  310  may determine to simultaneously perform the scan of the first link  331  and the second link  332  in response to the throughput of the first link  331  and the second link  332  being equal to or less than (or less than) the specified value. Simultaneously performing the scan of the first link  331  and the second link  332  may refer to simultaneously performing the scan of the first link  331  and the second link  332 . A situation in which the throughputs of the first link  331  and the second link  332  are less than or equal to (or less than) a specified value may be a situation in which the electronic device  310  performs relatively small short-range wireless communication. Accordingly, the electronic device  310  may reduce the time (or the time required for scanning) when data transmission and/or reception is interrupted by simultaneously scanning the first link  331  and the second link  332 . 
     In operation  1120 , the electronic device  310  may stop transmitting and/or receiving data through the first link  331  in response to determining to perform the scan of the first link  331  and the second link  332  sequentially, and may perform at least one operation for transmitting and/or receiving data through the second link  332 . 
     The electronic device  310  may stop transmitting and/or receiving data through the first link  331 , and may modify (and/or set) the first mapping data and/or the second mapping data as a portion of at least one or more operations to perform transmission and/or reception of data over the second link  332 . The electronic device  310  may modify the first mapping data and/or the second mapping data so that data to be transmitted through the link to be scanned (e.g., the first link  331 ) is transmitted through another link (e.g., the second link  332 ). 
     The electronic device  310  may modify the first mapping data and/or the second mapping data, based on characteristics of data to be transmitted through a link to be scanned (e.g., the first link  331 ). 
     According to an embodiment, the electronic device  310  may identify types of data included in the first mapping data, and may modify the second mapping data to include a data type (e.g., VO, VI) related to a service requiring low latency (e.g., video call and/or voice call) among characteristics of data included in the first mapping data. 
     For example, the electronic device  310  may add a data type (e.g., VO) related to a service requiring low latency (e.g., voice call) among the data types (e.g., BE, BK, VO) included in the first mapping data to the second mapping data. 
     According to another embodiment, the electronic device  310  may identify the characteristics of data included in the first mapping data, and may modify the second mapping data so that the second mapping data includes types of data included in the first mapping data. 
     For example, the electronic device  310  may add a data type (e.g., VO) not included in the second mapping data among data types (e.g., BE, BK, VO) included in the first mapping data to the second mapping data. 
     According to another embodiment, the electronic device  310  may modify the first mapping data and/or the second mapping data so that types of data included in the first mapping data and types of data included in the second mapping data are the same. In the above manner, the first mapping data and the second mapping data may include the same types of data. The electronic device  310  may transmit data that could have been transmitted through the first link  331  through the second link  332  while performing the scan of the first link  331 . 
     The electronic device  310  may transmit and/or receive data to the external electronic device  320  through a third link (not shown) supporting a transmission rate and/or reception rate relatively higher than that of the second link  332 . The electronic device  310  may generate and/or manage third mapping data including the type of data that may be transmitted or received through the third link. 
     The first mapping data, the second mapping data, and/or the third mapping data may be stored in a memory (e.g., the memory  130  of  FIG.  1   ) implemented inside or outside the electronic device  310 . 
     When data transmission and/or reception is possible through the third link before performing the scan of the first link  331 , the electronic device  310  may modify (and/or set) the third mapping data to include a data type related to a service requiring a low delay time among data types included in the first mapping data. The electronic device  310  may modify (and/or set) the second mapping data to include the type of data related to a service (e.g., a streaming service) that may be smoothly performed even with a relatively high latency among types of data included in the first mapping data. 
     Through the method described above, the electronic device  310  may transmit data related to a service requiring a low delay time among data to be transmitted through the first link  331  to the third link while performing the scan of the first link  331 , and may transmit data related to a service that may be smoothly performed even with a relatively high delay time to the second link  332 . 
     According to another embodiment, when data transmission and/or reception is possible through the third link before performing the scan of the first link  331 , the electronic device  310  may modify (and/or set) the third mapping data to include the type of data related to a service requiring a relatively low delay time among data transmitted by the electronic device  310 . The electronic device  310  may modify (and/or set) the second mapping data to include the type of data related to a service (e.g., a streaming service) that may be smoothly performed even with a relatively high delay time among the types of data transmitted by the electronic device  310 . 
     Through the method described above, while performing the scan of the first link  331 , the electronic device  310  may transmit data related to a service requiring a low delay time among data to be transmitted by the electronic device  310  through a third link, and may transmit data related to a service that may be smoothly performed even if the electronic device  310  has a relatively high delay time among data to be transmitted through the second link  332 . 
     The electronic device  310  may complete the modification of the first mapping data and/or the second mapping data, and may control the communication circuit  410  to transmit a signal instructing to stop data transmission and/or reception to the external electronic device  320  through the first link  331  before performing the scan operation for the first link  331 . 
     The short-range wireless communication defined in IEEE 802.11 may support various functions (e.g., a power management mode or APSD mode) capable of reducing power consumption by performing data transmission and/or reception after transmitting a signal. The electronic device  310  may transmit a signal instructing to stop data transmission and/or reception through the first link  331  using the power management mode or the APSD mode defined in short-range wireless communication. 
     The signal indicating that there is no data to be transmitted or received by the electronic device  400  through the first link  331  may be implemented in the form of an NDP as defined in IEEE 802.11, and the NDP may include a field (e.g., PWR MGT) indicating whether data to be transmitted or received by the electronic device  500  exists. The value (e.g., ‘0’) of a field indicating whether data to be transmitted or received by the electronic device  500  exists when data to be transmitted or received by the electronic device  500  exists, and the value (e.g., ‘1’) of a field indicating whether data to be transmitted or received by the electronic device  500  exists when data to be transmitted or received by the electronic device  500  does not exist may be different from each other. 
     In operation  1130 , the electronic device  310  may transmit and/or receive data through the second link  332  while scanning the first link  331 . 
     The electronic device  310  may transmit and/or receive data through the second link  332  while performing the scan operation for the first link  331 .

     It should be appreciated that various embodiments of the present disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element. 
     As used in connection with various embodiments of the disclosure, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC). 
     Various embodiments as set forth herein may be implemented as software (e.g., the program  140 ) including one or more instructions that are stored in a storage medium (e.g., internal memory  136  or external memory  138 ) that is readable by a machine (e.g., the electronic device  101 ). For example, a processor (e.g., the processor  120 ) of the machine (e.g., the electronic device  101 ) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium. 
     According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer&#39;s server, a server of the application store, or a relay server.
