According to an embodiment, when the electronic device is connected to the first external electronic device by providing a hotspot in the 2.4Ghz band, and the maximum throughput that can be achieved in the corresponding band is 144Mbps, the upper limit threshold of the throughput is 80% of 144Mbps. 115.2 Mbps. The maximum throughput may be changed according to the congestion degree of the frequency band, and accordingly, the threshold may also be changed.

Operations 610 to 640 may be performed by the processor 120 of the electronic device 101 described above with reference to FIG. 2 . According to an embodiment, operations 610 to 640 may correspond to the operation of determining the target frequency band described with reference to FIG. 3 (eg, operation 340 of FIG. 3 ).

According to an embodiment, in operation 610, the processor (eg, the processor 120 of FIG. 2 ) selects a supportable frequency band of the electronic device (eg, the electronic device 101 of FIG. 2 ) and a first external electronic device (eg, the first external electronic device) The changeable frequency band may be determined based on the supportable frequency band of the first external electronic device 102 of FIG. 2 . The supportable frequency band of the electronic device may be identified as described in operation 310 of FIG. 3 , and the supportable frequency band of the first external electronic device may be identified as described in operation 320 and FIG. 4A . According to an embodiment, the supportable frequency band of the first external electronic device may be stored in an external electronic device information storage (eg, the external electronic device information storage 135 of FIG. 2 ).

According to an embodiment, the processor (eg, the processor 120 of FIG. 2 ) may determine a common frequency band among two frequency bands as a changeable frequency band. For example, supportable frequency bands of the electronic device (eg, the electronic device 101 of FIG. 2 ) are 2.4Ghz, 5Ghz, 6Ghz, and 60Ghz, and the first external electronic device (eg, the first external electronic device of FIG. 2 ) When the supportable frequency bands of (102)) are 2.4Ghz, 5Ghz, and 6Ghz, and the two electronic devices are connected to the 5Ghz band through a hotspot, the changeable frequency bands may be determined to be 2.4Ghz and 6Ghz. However, the present invention is not limited thereto, and various embodiments may be possible depending on the supported frequency bands for each country. For example, supportable frequency bands of the electronic device (eg, the electronic device 101 of FIG. 2 ) are 2.4Ghz, 5Ghz, 6Ghz, and 30Ghz, and the first external electronic device (eg, the first external electronic device of FIG. 2 ) When the supportable frequency bands of (102)) are 2.4Ghz, 5Ghz, and 6Ghz, and the two electronic devices are connected to the 5Ghz band through a hotspot, the changeable frequency bands may be determined to be 2.4Ghz and 6Ghz.

According to an embodiment, in operation 620, the processor may determine the type of the band change event. For example, there may be two types of band change events: a band change event exceeding the upper limit threshold described in operation 540 of FIG. 5 and a band change event exceeding the lower limit threshold value described in operation 550 of FIG. 5 . However, the present invention is not limited thereto, and as described with reference to FIG. 5 , the state of the external electronic device may be divided into several types as the state is divided into several stages instead of the upper and lower threshold values.

According to an embodiment, in the case of a band change event exceeding the upper limit threshold (eg, "exceeding the upper limit threshold" in operation 620), in operation 630, the processor performs a second higher frequency based on the connected first frequency band among the changeable frequency bands. The band may be determined as a target frequency band. For example, when the first frequency band being connected is 5Ghz and the changeable frequency bands are 2.4Ghz and 6Ghz as described above, the processor may determine the 6Ghz frequency band as the target frequency band.

According to an embodiment, in case of a band change event exceeding the lower limit threshold (for example, in operation 620, “lower limit threshold is exceeded”), in operation 640, the processor performs a lower difference based on the connected first frequency band among the changeable frequency bands. The frequency band may be determined as the target frequency band. For example, when the first frequency band being connected is 5Ghz and the changeable frequency bands are 2.4Ghz and 6Ghz as described above, the processor may determine the 2.4Ghz frequency band as the target frequency band.

Since the required power consumption increases in the case of a higher frequency band, an embodiment of determining the next higher or lower frequency band as the target frequency band has been described in FIG. 6 , but the present invention is not limited thereto. According to an embodiment, the processor (eg, the processor 120 of FIG. 2 ) is the most changeable frequency band among the changeable frequency bands based on the power state of the electronic device (eg, the electronic device 101 of FIG. 2 ) providing the hotspot. A high frequency band may be determined as the target frequency band, and another frequency band may be determined as the target frequency band according to a change in power level. According to an embodiment, the processor may determine the target frequency band by combining the power state of the electronic device (eg, the electronic device 101 of FIG. 2 ), the latency required by the access category, and the throughput.

According to an embodiment, in operation 720 , the processor (eg, the processor 120 of FIG. 2 ) operates the first external electronic device (eg, the first external electronic device of FIG. 2 ) as described in operations 320 and 4A of FIG. 3 . ( 102 )) and a second external electronic device (eg, the second external electronic device 104 of FIG. 2 ) can check supportable frequency bands.

According to an embodiment, in

operations

730 and 740 , the processor (eg, the processor 120 of FIG. 2 ) operates the first external electronic device (eg, FIG. 2 ) as described in

operations

330 and 340 of FIG. 3 and FIG. 5 . 2 ) and the second external electronic device (eg, the second external electronic device 104 of FIG. 2 ) may be monitored to determine whether a band change event occurs.

According to an embodiment, a first external electronic device (eg, the first external electronic device 102 of FIG. 2 ) and a second external electronic device (eg, the first external electronic device 102 of FIG. 2 ) in a first frequency band connected to the electronic device (eg, the electronic device 101 of FIG. 2 ) The throughput threshold may be set based on the summed throughput that the external electronic device (eg, the second external electronic device 104 of FIG. 2 ) can process. For example, the processor may set 80% of the sum of the maximum throughput of each external electronic device as the upper limit threshold value and 50% as the lower limit threshold value. According to an embodiment, when the electronic device is connected to the first external electronic device and the second external electronic device by providing a hotspot in the 2.4Ghz band, and the maximum performance that the two external electronic devices can provide in the corresponding band is 144Mbps The upper limit threshold of the throughput may be 230.4 Mbps, which is 80% of the summed throughput of 288 Mbps. As described with reference to FIG. 5 , the maximum performance may be changed according to the degree of congestion of the frequency band, and accordingly, the threshold may also be changed.

According to another embodiment, in operation 740, the processor may set an upper limit threshold value and a lower limit threshold value based on a round trip time (RTT) as described in operation 520 of FIG. 5 . According to an embodiment, a recommended round trip time for each service category provided by the first external electronic device and the second external electronic device is determined, and a round trip time threshold value may be set based on the determined round trip time. In the case of round-trip time, unlike throughput, when there are a plurality of external electronic devices, the threshold value may be set based on a shorter round-trip time instead of based on the summed value. For example, the processor sets a certain percentage of the shorter recommended round trip time (e.g. 120%) of the two recommended round trip times as the upper threshold, and sets another percentage of the shorter recommended round trip time (e.g. 80%) as the lower threshold threshold. It can be set as a value.
