output, as the user interface, one of a first user interface representing that the history of the pairing with the wearable device is absent, a second user interface representing that the history of the pairing with the wearable device is present, or a third user interface representing that the user account information is identical to user account information of the wearable device.

3. The electronic device of claim 2 ,

wherein the memory stores a list of a device previously paired with the electronic device, and

wherein the processor is further configured to determine whether a pairing history exists by determining whether the device identification information is included in the list.

4. The electronic device of claim 3 , wherein the processor is further configured to:

output the first user interface when the device identification information is not included in the list.

5. The electronic device of claim 3 , wherein the processor is further configured to:

determine whether the second wireless communication scheme is activated, when the device identification information is included in the list.

6. The electronic device of claim 5 , wherein the processor is further configured to:

automatically perform the pairing with the wearable device when the second wireless communication scheme is activated.

7. The electronic device of claim 5 , wherein the processor is further configured to:

compare first user account information of the electronic device with second user account information of the wearable device, which is included in the first advertising signal, when the second wireless communication scheme is not activated.

8. The electronic device of claim 7 , wherein the processor is further configured to:

output the third user interface including a user identifier (ID) based on the first user account information or the second user account information, when the first user account information is identical to the second user account information.

9. The electronic device of claim 1 , wherein the processor is further configured to:

when the first advertising signal has intensity equal to or less than a preset reference value, compare first user account information of the electronic device with second user account information of the wearable device, which is included in the first advertising signal; and

output the user interface.

10. The electronic device of claim 9 , wherein the processor is further configured to:

output the user interface including a user ID based on the first user account information or the second user account information, when the first user account information is identical to the second user account information.

11. The electronic device of claim 1 , wherein the processor is further configured to:

terminate outputting the user interface when intensity of the first advertising signal is changed to be equal to or less than a preset reference value.

12. The electronic device of claim 1 ,

wherein the first wireless communication scheme is a communication scheme based on a Bluetooth low energy (BLE) technology, and

wherein the second wireless communication scheme is a communication scheme based on a Bluetooth (BT) technology.

13. The electronic device of claim 1 ,

wherein the first advertising signal includes information on a number of devices allowing simultaneous pairings with the wearable device, and

wherein the processor is further configured to output the user interface when a number of devices in a pairing state with the wearable device is smaller than the number of the devices allowing the simultaneous pairings with the wearable device.

14. The electronic device of claim 1 , wherein the user interface includes a device recognition mark for indicating a pairing state of the electronic device.

15. A method for wirelessly communicating with a wearable device, the method comprising:

receiving, from the wearable device, a first advertising signal including device identification information of the wearable device and pairing information representing whether the wearable device is currently paired with another device, through a first wireless communication scheme;

determining, based on the pairing information, whether the wearable device is currently paired with an electronic device;

outputting a user interface for performing a pairing with the wearable device, if at least one of a history of a pairing with the wearable device and user account information in common with the wearable device is present, when the wearable device is not paired;

performing the pairing with the wearable device, in response to a user input received through the output user interface;

transceiving, with the wearable device, data based on a second wireless communication scheme when the pairing is completed; and

if a second advertising signal from the wearable device is received while the user interface is output, terminating the user interface in response to the second advertising signal indicating that the wearable device is paired with another device.

16. The method of claim 15 , wherein the outputting of the user interface includes:

outputting, as the user interface, one of a first user interface representing that the history of the pairing with the wearable device is absent, a second user interface representing that the history of the pairing with the wearable device is present, or a third user interface representing that the user account information is identical to user account information of the wearable device.

17. The method of claim 15 , wherein the outputting of the user interface includes:
