Abstract

Disclosed is an electronic device including a wireless communication circuit configured to support communication connections to one or multiple devices, at least one processor, and a memory which stores instructions causing, when executed, the at least one processor to identify whether a first communication connection to a second external device through the wireless communication circuit is disconnected, acquire, if disconnection of the first communication connection is identified, communication state information from a first external device connected through the wireless communication circuit, identify, based on the acquired communication state information, whether a second communication connection between the first external device and the second external device is disconnected, and operate in a loss occurrence mode for the second external device if disconnection of the second communication connection is identified.

determine, if the first communication connection is disconnected, a location of the second external device, based on the acquired location information, and

determine to operate, if the determined location of the second external device is in a risk area, in the second loss mode for the second external device without receiving the communication state information from the first external device.

5 . The electronic device of claim 1 ,

wherein the instructions, when executed by the at least one processor, further cause the electronic device to:

acquire, if the first communication connection is not disconnected, the communication state information from the first external device, and

determine to operate in the first loss mode for the second external device if disconnection of the second communication connection is identified based on the acquired communication state information.

6 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor, further cause the electronic device to, if the second communication connection is disconnected, transmit information on the occurrence of connection loss for the second external device to an external server by using the wireless communication circuit in the second loss.

7 . The electronic device of claim 6 ,

wherein the electronic device further comprises a display, a speaker, or a vibration generation module, and

wherein the instructions, when executed by the at least one processor, further cause the electronic device to output a notification to notify a user that the second external device has been lost, by using at least one of the display, the speaker, or the vibration generation module in the second loss mode for the second external device.

8 . A method of an electronic device, the method comprising:

identifying whether a first communication connection to a second external device is disconnected;

if disconnection of the first communication connection is identified, acquiring communication state information from a first external device;

based on the acquired communication state information, identifying whether a second communication connection between the first external device and the second external device is disconnected;

if the second communication connection is maintained, determining to operate in a first less mode or a second loss mode for the second external device, based on location information of the second external device identified while the first communication connection is maintained,

when in the first loss mode, transmit information indicating a risk of connection loss for the second external device to the first external device; and

when in the second loss mode, transmitting information indicating an occurrence of connection loss for the second external device to the first external device, and

if the second communication connection is disconnected, determining to operate in the second loss mode for the second external device and transmitting the information indicating the occurrence of connection loss for the second external device to the first external device.

9 . The method of claim 8 , further comprising, if the second communication is maintained, transmitting a reconnection request to the second external device.

10 . The method of claim 9 ,

wherein transmitting the reconnection request to the second external device comprises configuring a transmission period of the reconnection request to be less than a designated period, or configuring a signal strength of the reconnection request to be greater than a designated signal strength.

11 . The method of claim 8 , further comprising:

acquiring the location information of the second external device by using at least one sensor;
