value of the first information first scan policy 0 RSSI>-30dBm One RSSI>-40dBm 2 RSSI>-45dBm 3 RSSI>-50dBm 4 RSSI>-55dBm 5 RSSI>-60dBm 6 RSSI>-65dBm 7 RSSI>-70dBm 8 RSSI>-75dBm 9 RSSI>-90dBm

Server Upload Behavior Control
value of the first information first scan policy 0 RSSI>-30dBm One RSSI>-75dBm 2 RSSI>-70dBm 3 RSSI>-65dBm 4 RSSI>-60dBm 5 RSSI>-55dBm 6 RSSI>-50dBm 7 RSSI>-45dBm 8 RSSI>-40dBm 9 RSSI>-90dBm

In an embodiment, the first scan policy may consist of ranges of received signal quality corresponding to values of the first information for server upload operation control. The electronic device 301 may identify the range of the received signal quality corresponding to the first information on the server upload operation control included in the payload of the first packet from among the plurality of received signal quality ranges. The electronic device 301 may determine whether the received signal quality of the first packet is included in the range of the received signal quality corresponding to the value of the checked first information for server upload operation control.

In an embodiment, the state in which the first packet in operation 430 satisfies the first scan policy associated with the received signal quality set in the electronic device 301 is one of a plurality of received signal quality ranges constituting the first scan policy. It may mean a state in which the received signal quality of the first packet is included in the received signal quality range corresponding to the value of the first information for server upload operation control.

For example, it is assumed that the first scan policy of the electronic device 301 is configured based on <Table 1>, and the value of the first information for server upload operation control included in the first packet is “8”, and the first The received signal quality of the packet, for example, the received signal strength (RSSI) is assumed to be “-60dBm”.

Based on <Table 1>, the electronic device 301 indicates that the received signal strength of “-60dBm” of the first packet corresponds to “8”, which is the value of the first information, among a plurality of received signal strength ranges. It can be checked whether the range of “RSSI>-75dBm” is satisfied. Based on the fact that “-60 dBm”, which is the received signal strength of the first packet, is greater than “-75 dBm”, the electronic device 301 determines that the received signal strength of the first packet is received according to the first scan policy of the electronic device 301 . It can be confirmed that it is included in the signal strength range. Based on being included in the received signal strength range according to the first scan policy, the electronic device 301 may determine that the first packet satisfies the first scan policy of the electronic device 301 . In this case, as the first packet satisfies the first scan policy of the electronic device 301 , the electronic device 301 may perform operation 440 to be described later.

As another example, it is assumed that the first scan policy of the electronic device 301 is configured based on <Table 2>, and the value of the first information for server upload operation control included in the first packet is “8”, , assuming that the received signal quality of the first packet, for example, the received signal strength (RSSI), is “-60dBm”.

Based on <Table 2>, the electronic device 301 determines that the received signal strength of “-60dBm” of the first packet corresponds to “8”, which is the value of the first information, among a plurality of received signal strength ranges. It can be checked whether the range of “RSSI>-40dBm” is satisfied. The electronic device 301 determines that the strength of the received signal of the first packet is based on the first scan policy of the electronic device 301 based on the fact that “-60dBm”, which is the strength of the received signal of the first packet, is less than “-40dBm”. It can be confirmed that it is not included in the range of the received signal strength. Based on not being included in the range of the received signal strength according to the first scan policy, the electronic device 301 may determine that the first packet does not satisfy the first scan policy of the electronic device 301 . In this case, since the first packet does not satisfy the first scan policy, the electronic device 301 may not perform operation 440 to be described later.

In various embodiments, the value of the first information for the server upload operation control according to <Table 1> and the first scan policy corresponding to the value of the first information are the first scan policy for the server upload operation control according to <Table 2> The value of 1 information and the first scan policy corresponding to the value of the first information may be the same as or different from each other.

For another example, when the value of the first information for server upload operation control according to <Table 1> and <Table 2> is “1 to 8”, corresponding to each of “1 to 8” that is the value of the first information The first scan policy may be different.

In various embodiments, in <Table 1> and <Table 2>, the value of the first information (eg, “0” and “9”) for the server upload operation control having the same first scan policy and the value of the first information The first scan policy (eg, “RSSI>-30dBm” and “RSSI>-90dBm”) corresponding to the values (eg, “0” and “9”) may be pre-stored in the first external electronic device 220 . can When the first external electronic device 220 requires a quick upload to the server 240 and a quick discovery of the first external electronic device 220 , the received signal among the values of the first information having the same first scan policy stored in advance A first packet including a first information value (eg, “9”) corresponding to a range in which the reference value of the intensity is low may be broadcast. When fast upload to the server 240 and quick discovery of the first external electronic device 220 are not required, the first external electronic device 220 stores a value of the first information that does not have the same first scan policy ( Example: “one of 1 to 8”) may be determined, and the first packet including the determined value of the first information may be broadcast.

In this case, the electronic device 301 may set the reference value of each of the plurality of received signal quality ranges to be lower than the specified reference value, and configure the first scan policy based on the reference value. For example, setting the reference value of each of the ranges for the plurality of received signal quality to be lower than the specified reference value may mean setting the received signal quality, for example, the received signal strength (RSSI), to be lower than the specified reference received signal strength. have. As the reference value of the range for the received signal quality is set to be lower than the specified reference value, the probability that the first packet broadcast from the first external electronic device 220 satisfies the first scan policy may increase.

If there is one history, the electronic device 301 may set the reference value of each of the plurality of received signal quality ranges to be higher than the specified reference value, and configure the first scan policy based thereon. As the reference value of the range for the received signal quality is set to be higher than the specified reference value, the probability that the first packet broadcast from the first external electronic device 220 satisfies the first scan policy may decrease. When the probability that the first packet satisfies the first scan policy is low, the electronic device 301 may not perform operation 440 to be described later.

As the operation of transmitting the identification information of the first external electronic device 220 and the operation of acquiring the location information of the electronic device 301 to the server 240 is performed only when the packet satisfies the first scan policy, the electronic It is possible to prevent resource waste of the device 301 .

In various embodiments, it has been described that only the electronic device 301 receives the first packet broadcast from the first external electronic device 220 , but the present invention is not limited thereto. The first packet broadcast from the first external electronic device 220 is transmitted to a plurality of electronic devices (eg, 210a, 210b, 210c, and/or 210d of FIG. 2 ) located in a short distance to the first external electronic device 220 . ) can be received. In this case, each of the plurality of electronic devices may have the same first scan policy or may have different first scan policies. For example, assuming that each of the plurality of electronic devices, for example, the first electronic device and the second electronic device has a different first scan policy, the second electronic device receiving the first packet broadcast from the first external electronic device 220 . One electronic device may have a first scan policy according to the above-described <Table 1>, and the second electronic device that receives the first packet broadcast from the first external electronic device 220 may have the above-mentioned <Table 2> may have a first scan policy according to

In various embodiments, when the first packet broadcast from the first external electronic device 220 is received by a plurality of electronic devices, for example, the first electronic device and the second electronic device, the first electronic device and the second electronic device As each electronic device is set with a different first scan policy, the first packet may or may not satisfy the first scan policy of each electronic device. For example, since the first packet satisfies the first scan policy according to <Table 1>, the first electronic device transmits the identification information of the first external electronic device 220 and the location information of the first electronic device to the server (eg: may be transmitted to the server 240 of FIG. 2 ). As another example, since the first packet does not satisfy the first scan policy according to <Table 2>, the second electronic device uses the identification information of the first external electronic device 220 and the location information of the second electronic device The operation of transmitting to the server 240 may not be performed.

In FIG. 4 according to various embodiments of the present disclosure, the electronic device 301 identifies the first information on the server upload operation control included in the first packet based on the identification of the first packet in operation 420 as a packet associated with loss. After that, it has been described as checking whether the first packet satisfies the first scan policy related to the received signal quality set in the electronic device 301 based on the first information on the control of the server upload operation in operation 430 , but limited to this is not doing For example, the electronic device 301 may determine whether the first packet satisfies the first scan policy associated with the received signal quality set in the electronic device 301 based on the identification of the first packet as a packet associated with loss. have. When the first packet satisfies the first scan policy associated with the received signal quality set in the electronic device 301, the electronic device 301 checks the first information on the server upload operation control included in the first packet, Based on the first information, identification information of the first external electronic device 220 and location information of the electronic device 301 generated based on the first packet may be transmitted to the server 240 .

Referring to FIG. 5 , the electronic device (eg, the electronic device 301 of FIG. 3 ) may change a first scan policy to a second scan policy in operation 510 .

In operation 510 according to various embodiments of the present disclosure, in operation 440 of FIG. 4 described above, the electronic device 301 receives identification information and electronic information of the first external electronic device (eg, the first external electronic device 220 of FIG. 2 ). After transmitting the location information of the device 301 (and/or location information of the first external electronic device 220 confirmed by the electronic device 301) to a server (eg, the server 240 of FIG. 2 ), When receiving another packet (eg, a second packet) broadcast from the first external electronic device 220 , the server 240 transmits the identification information of the first external electronic device 220 and the location information of the electronic device 301 to the server 240 . ) can be performed to reduce the number of retransmission operations. For example, the reference value of the range for each received signal quality constituting the second scan policy may be set higher than the reference value of the range for each received signal quality constituting the first scan policy. For example, setting the reference value of the range for each received signal quality constituting the second scan policy to be higher than the reference value of the range for each received signal quality constituting the first scan policy is to set the received signal quality, for example, the second It may mean that each received signal strength (RSSI) constituting the scan policy is set higher than each received signal strength constituting the first scan policy.

For example, when the electronic device 301 is configured with the first scan policy according to <Table 1>, the electronic device 301 may change to the second scan policy according to <Table 3> below. The reference value of the range for the received signal quality corresponding to the value of the second information for server upload operation control of the second scan policy according to <Table 3> below is the server upload of the first scan policy according to <Table 1> It may be equal to or lower than the reference value of the range for the received signal quality corresponding to the value of the first information for the operation control.

As another example, when the electronic device 301 is configured with the first scan policy according to <Table 2>, the electronic device 301 may change to the second scan policy according to the following <Table 4>. The reference value of the range for the received signal quality corresponding to the value of the second information for the server upload operation control of the second scan policy according to <Table 4> is the server upload of the first scan policy according to <Table 2> It may be equal to or higher than the reference value of the range for the received signal quality corresponding to the value of the first information for the operation control.

In various embodiments, the electronic device 301 may include a plurality of electronic devices (eg, the plurality of electronic devices 210a, 210b, 210c, and 210d of FIG. 2 ). In this case, each of the plurality of electronic devices may have the same second scan policy or may have different second scan policies.

In various embodiments, at least one electronic device configured to search for the first external electronic device 220 among a plurality of electronic devices (eg, the plurality of electronic devices 210a, 210b, 210c, and 210d of FIG. 2 ). (eg, at least one of the plurality of electronic devices 210a, 210b, 210c, and 210d of FIG. 2 ) may receive the second scan policy from the server 240 .

In an embodiment, in operation 520 , the electronic device 301 may receive a second packet broadcast from the first external electronic device 220 . For example, the electronic device 301 may receive a second packet broadcast from the first external electronic device 220 through short-range wireless communication. The payload of the second packet includes information on a lost state and/or server upload. It may include information on motion control (eg, second information).

The present invention is not limited thereto, and in various embodiments, the payload of the second packet may include identification information of the first external electronic device 220 . For example, the identification information of the first external electronic device 220 may include a MAC address, a model number, and/or a serial number of the first external electronic device 220 . The present invention is not limited thereto, and the payload of the second packet may include identification information of the second external electronic device 230 , for example, the MAC address, model number, and/or serial number of the second external electronic device 230 . may be

In an embodiment, in operation 530 , the electronic device 301 may check second information for controlling a server upload operation included in the second packet. For example, the second information on server upload operation control included in the second packet in operation 530 is the same as the first information on server upload operation control included in the payload of the first packet in operation 420, or may be different. For example, when the remaining battery level of the first external electronic device 220 is changed or a condition for controlling a server upload operation is changed, the first information and the second information may be different.

In an embodiment, in operation 540 , the electronic device 301 may determine whether the second packet satisfies the second scan policy based on the second information on the server upload operation control.

For example, the second scan policy may be configured with a plurality of received signal quality ranges as shown in Table 3 or Table 4 above. The electronic device 301 may identify the range of the received signal quality corresponding to the second information on the server upload operation control included in the payload of the second packet from among the plurality of received signal quality ranges. The electronic device 301 may determine whether the received signal quality of the second packet is included in the range of the received signal quality corresponding to the value of the checked second information for server upload operation control.

In an embodiment, the state in which the second packet in operation 540 satisfies the second scan policy is based on the value of the second information for server upload operation control among a plurality of received signal quality ranges constituting the second scan policy. It may mean a state in which the received signal quality of the second packet is included in the range of the corresponding received signal quality.

For example, it is assumed that the second scan policy of the electronic device 301 is configured based on <Table 3>, the value of the second information for server upload operation control included in the second packet is “8”, and the second The received signal quality of the packet, for example, the received signal strength (RSSI) is assumed to be “-60dBm”.

Based on <Table 3>, the electronic device 301 determines that the received signal strength of “-60dBm” of the second packet corresponds to “8”, which is the value of the second information, among a plurality of received signal strength ranges. It can be checked whether the range of “RSSI>-40dBm” is satisfied. Based on the fact that the received signal strength of the second packet “-60dBm” is less than “-40dBm”, the received signal strength of the second packet is not included in the received signal strength range according to the second scan policy of the electronic device 301 . can confirm that it is not. Based on not being included in the range of the received signal strength according to the second scan policy, the electronic device 301 may determine that the second packet does not satisfy the second scan policy of the electronic device 301 . In this case, since the second packet does not satisfy the second scan policy, the electronic device 301 may not perform operation 550, which will be described later.

As another example, it is assumed that the second scan policy of the electronic device 301 is configured based on <Table 4>, and the value of the second information for server upload operation control included in the second packet is “8”, , assuming that the received signal quality of the second packet, for example, the received signal strength (RSSI), is “-60dBm”.

Based on <Table 4>, the electronic device 301 determines that the received signal strength “-60 dBm” of the second packet corresponds to “8”, which is the value of the second information, among the plurality of received signal strength ranges. It can be checked whether the range of “RSSI>-75dBm” is satisfied. The electronic device 301 receives the received signal strength of the second packet according to the second scan policy of the electronic device 301 based on the fact that “-60dBm”, which is the received signal strength of the second packet, is greater than “-75dBm”. It can be confirmed that it is included in the signal strength range. Based on being included in the received signal strength range according to the first scan policy, the electronic device 301 may determine that the second packet satisfies the second scan policy of the electronic device 301 . In this case, as the first packet satisfies the first scan policy of the electronic device 301 , the electronic device 301 may perform operation 550 , which will be described later.

In various embodiments, the value of the second information for the server upload operation control according to <Table 3> and the second scan policy corresponding to the value of the second information are the second scan policies for the server upload operation control according to <Table 4> The value of the information and the second scan policy corresponding to the value of the second information may be the same as or different from each other. For example, when the values of the second information for server upload operation control according to <Table 3> and <Table 4> are “0” and “9”, corresponding to the values of “0” and “9” of the second information The second scan policy may be the same as “RSSI>-30dBm” and “RSSI>-90dBm.” As another example, of the second information for server upload operation control according to <Table 3> and <Table 4> When the value is “1 to 8”, the second scan policy corresponding to each of “1 to 8”, which is the value of the second information, may be different.

In various embodiments, in <Table 3> and <Table 4>, the value of the second information for the server upload operation control having the same second scan policy (eg, “0” and “9”) and the value of the second information The second scan policy (eg, “RSSI>-30dBm” and “RSSI>-90dBm”) corresponding to the values (eg, “0” and “9”) may be pre-stored in the first external electronic device 220 . can When a fast upload to the server 240 and a quick discovery of the first external electronic device 220 are required, the first external electronic device 220 receives a received signal from among the values of the second information having the same second scan policy stored in advance. A second packet including a second information value (eg, “9”) corresponding to a range in which the reference value of the intensity is low may be broadcast. When the first external electronic device 220 does not require fast upload to the server 240 and quick discovery of the first external electronic device 220 , the value of the second information that does not have the same second scan policy stored in advance ( Example: “one of 1 to 8”) may be determined, and a second packet including the determined value of the second information may be broadcast.

In an embodiment, when the second packet satisfies the second scan policy, in operation 550 , the electronic device 301 generates identification information of the first external electronic device 220 based on the second packet and the electronic device. The location information of 301 may be transmitted to the server 240 .

In various embodiments, the electronic device 301 uses the electronic device 301 as well as identification information of the first external electronic device 220 and location information of the electronic device 301 generated based on the second packet. The confirmed location information of the first external electronic device 220 may be transmitted to the server 240 . For example, the electronic device 301 transmits/receives data to and from the first external electronic device 220 using the UWB module, and based on this, a distance and/or direction (eg, azimuth and / or altitude) can be determined. The electronic device 301 may identify the location of the first external electronic device 220 based on the determined distance and/or direction to the first external electronic device 220 , and the identified first external electronic device 220 . location information of may be transmitted to the server 240 .

The location information of the electronic device 301 transmitted to the server 240 in operation 550 according to various embodiments may be different from the location information of the electronic device 301 transmitted to the server 240 in operation 440 of FIG. 4 . can For example, the electronic device 301 may be in a moving state, and as the first packet and the second packet broadcast from the external electronic device 220 are received while moving, identification information of the first external electronic device 220 is received. The location information of the electronic device 301 may be different at the time of transmitting to the server 240 .

In various embodiments, although not shown, the first information included in the first packet in operation 430 of FIG. 4 and the second information included in the second packet in operation 530 are the same, and in operation 440 of FIG. When the location information of the electronic device 301 transmitted to the server 240 does not change (eg, when the location information is not changed because the electronic device 301 is not in a moving state), the electronic device 301 may not perform operation 550.

In various embodiments, after transmitting the identification information of the first external electronic device 220 in operation 440 of FIG. 4 to the server 240, the range of each received signal quality constituting the first scan policy is As the second scan policy is changed to a range for each received signal quality with a reference value higher than the reference value, the probability that the second packet broadcast from the first external electronic device 220 satisfies the second scan policy increases can be lowered Accordingly, the electronic device 301 can reduce the number of times that the identification information of the first external electronic device 220 is transmitted to the server 240 (eg, duplicate identification information of the first external electronic device 220 and The operation of transmitting the location information of the electronic device 301 to the server 240 can be avoided), and the efficiency of resource use of the electronic device 301 can be improved.

In various embodiments, although not shown, after performing operation 550, the electronic device 301 may check whether a specified time has elapsed. When the specified time elapses, the electronic device 301 may lower the reference value of the range for each received signal quality constituting the second scan policy. For example, lowering the reference value of each of the plurality of received signal quality ranges constituting the second scan policy means setting the received signal quality, for example, each received signal strength (RSSI) to be lower than the currently set received signal strength. can do. Accordingly, after a specified time has elapsed, the probability that the broadcast packet satisfies the scan policy increases, so that the server 240 provides identification information of the first external electronic device 220 and the location of the electronic device 301 . An operation of transmitting information may be performed.

According to various embodiments, in FIGS. 4 and 5 , it is assumed that a packet (eg, a first packet and a second packet) broadcast from one first external electronic device 220 is received, but this is not limited thereto. is not doing At least one electronic device 210a, 210b, 210c, and/or 210d may receive packets broadcast from a plurality of external electronic devices located in a short distance, and each electronic device (eg, 210a in FIG. 2 , 210b, 210c, or 210d) is identification information of an external electronic device and location information of the electronic device 301 according to whether a received packet satisfies a set scan policy (eg, a first scan policy and a second scan policy) It is possible to dynamically control the operation of transmitting to the server (240).

6 is a flowchart 600 for explaining a method of broadcasting a packet by the first external electronic device 220 according to various embodiments of the present disclosure.

Operations 610 to 690 of FIG. 6 according to various embodiments may be performed by a first external electronic device (eg, the first external electronic device 220 of FIG. 2 ).

Referring to FIG. 6 , in operation 610 , the first external electronic device 220 may communicate with a second external electronic device (eg, the second external electronic device 230 of FIG. 2 ). For example, the first external electronic device 220 communicates with the second external electronic device 230 through short-range wireless communication (eg, Wi-Fi, Bluetooth, Bluetooth low energy (BLE), or infrared data association (IrDA)). ) and a wireless communication link can be established.

In an embodiment, in operation 620 , the first external electronic device 220 may determine whether a communication connection with the second external electronic device 230 is released. For example, the first external electronic device 220 moves away from the second external electronic device 230 by a distance exceeding a specified distance, and/or the quality of a signal received from the second external electronic device 230 (eg, When it is determined that reference signal received power (RSRP), reference received quality (RSRQ), or received signal strength indication (RSSI) is less than a specified value, the communication connection with the second external electronic device 230 may be released.

In an embodiment, if it is confirmed that the communication connection with the second external electronic device 230 has been released (eg, YES in operation 620 ), the first external electronic device 220 may determine the lost state in operation 630 . . If it is confirmed that the communication connection with the second external electronic device 230 has not been released (eg, NO in operation 620 ), the first external electronic device 220 communicates with the second external electronic device 230 in operation 610 . You can continue to do it.

In an embodiment, in operation 640 , the first external electronic device 220 may determine first information for controlling the server upload operation based on the state and/or context information of the first external electronic device 220 . . The state information of the first external electronic device 220 may include battery state information (eg, remaining battery amount information). The context information of the first external electronic device 220 may include context information based on location information received from the second external electronic device 230 before the communication connection with the second external electronic device 230 is released. . The first external electronic device 220 includes battery state information (eg, remaining battery level information) of the first external electronic device 220 and context information (eg, second external electronic device 230 ) of the first external electronic device 220 . ) and the situation information based on location information received from the second external electronic device 230 before the communication connection is released), the first information for controlling the server upload operation may be determined.

For example, if the remaining battery power of the first external electronic device 220 is less than or equal to a specified value and/or it is determined that the first external electronic device 220 is located in a dangerous area, the first external electronic device 220 may The value of the first information for server upload operation control may be determined as a value that may be included in the range of the first received signal quality. In other words, when the first packet including the first information is broadcast, the remaining battery level of the first external electronic device 220 is less than or equal to a specified value, and/or the first external electronic device 220 is located in a dangerous place. If the location is confirmed, the server upload operation is performed so that the probability of satisfying the scan policy of at least one electronic device 301 receiving the first packet is increased, recognizing that the first external electronic device 220 needs to be found quickly. A value of the first information for the control may be determined. For example, if it is confirmed that the first external electronic device 220 requires a quick upload to the server 240 and a quick discovery of the first external electronic device 220 is required, it is shown in <Table 1> or <Table 2>. As a value corresponding to a range in which the reference value of the received signal strength is low among the values of the first information based on the first information value, the first information value (eg, “9”) for controlling the server upload operation may be determined.

As another example, when it is determined that the remaining battery power of the first external electronic device 220 exceeds a specified value and/or it is determined that the first external electronic device 220 is not located in the hazardous area, the first external electronic device 220 may determine the value of the first information for server upload operation control as a value that may be included in the range of the second received signal quality having a range of the received signal quality higher than the range of the first received signal quality. In other words, when the first packet including the first information is broadcast, the remaining battery capacity of the first external electronic device 220 is exceeded and/or the first external electronic device 220 is not located in a dangerous place. If it is confirmed that there is no need to search for the first external electronic device 220 quickly, the server upload operation is performed so that the probability of satisfying the scan policy of the at least one electronic device 301 receiving the first packet is lowered. A value of the first information for the control may be determined. For example, if it is determined that the first external electronic device 220 does not require fast upload to the server 240 and quick discovery of the first external electronic device 220, <Table 1> or <Table 2> Based on , a value (eg, one of “1 to 8”) of the first information for server upload operation control may be determined.

In various embodiments, although not shown, the first external electronic device 220 determines the broadcast period of the first packet, the number of broadcasts, and/or set broadcast power.

For example, when it is determined that the remaining battery level of the first external electronic device 220 is less than or equal to a specified value and/or it is determined that the first external electronic device 220 is located in a dangerous area, the first external electronic device 220 uploads and releases the data quickly to the server 240 . 1 For quick discovery of the external electronic device 220, the number of broadcast times (and/or periods) of the first packet is set to be greater than or equal to the specified number (and/or period), and the broadcast power is set to be greater than or equal to the specified power value. can As another example, when the remaining battery power of the first external electronic device 220 exceeds a specified value, and/or when it is determined that the dangerous area is not located in the first external electronic device 220, the The number of broadcasts (and/or period) may be set to less than a specified number of times (and/or period), and the broadcast power may be set to less than the specified power.

The present invention is not limited thereto, and the payload of the first packet may include identification information of the second external electronic device 230 , for example, the MAC address, model number, and/or serial number of the second external electronic device 230 . may be

In another embodiment, the first external electronic device 220 may generate a plurality of first packets in which the first information is set differently and broadcast them.

According to various embodiments, the second information on the server upload operation control in operation 680 may be the same as or different from the first information on the server upload operation control in operation 640 . For example, based on the state of the first external electronic device 220, for example, changed battery information of the first external electronic device 220, movement information of the first external electronic device 220, and/or context information, It is possible to determine second information for controlling the server upload operation. The determined second information may have a range of a received signal quality for server upload operation control that is the same as or different from that of the first information.

When communication with the second external electronic device 230 is not reconnected, the first external electronic device 220 may broadcast a second packet based on a specified condition. For example, as the specified condition, the period and/or number of broadcasting the second packet may be set differently based on the battery state of the first external electronic device 220 .
