First claim

What is claimed is:

1. An electronic device comprising:
a first communication circuit supporting communication based on Bluetooth protocol;
a second communication circuit supporting communication based on an ultra-wideband (UWB) protocol;
a processor operatively connected to the first communication circuit and the second communication circuit; and
a memory operatively connected to the processor,
wherein the memory stores instructions that, when executed by the processor, cause the electronic device to:
transmit an advertising signal using the first communication circuit;
establish a Bluetooth connection with each of a plurality of external electronic devices based on one or more response signals for the advertising signal using the first communication circuit;
receive identifiers from each of the plurality of external electronic devices over the Bluetooth connection;
accessing a database using the received identifiers from each of the plurality of external electronic devices to identify accounts associated with each one of the plurality of external electronic devices and determine which ones of the plurality of external electronic devices are associated with a same account as the electronic device;
determine a ranging device among the ones of the plurality of external electronic devices based on communication quality related to the plurality of external electronic devices;
release connections with the plurality of external electronic devices other than the ranging device; and
perform exclusive UWB ranging with the determined ranging device using the second communication circuit.

2. The electronic device of claim 1 , wherein the instructions, when executed by the processor, cause the electronic device to determine, as the ranging device, a first external electronic device having highest communication quality among the ones of the plurality of external electronic devices.

3. The electronic device of claim 1 , wherein the instructions, when executed by the processor, cause the electronic device to determine, as the ranging device, a first external electronic device having highest reception sensitivity or highest reception strength among the ones of the plurality of external electronic devices.

4. The electronic device of claim 1 , wherein the instructions, when executed by the processor, cause the electronic device to determine, as the ranging device, a first external electronic device having a lowest error rate among the ones of the plurality of external electronic devices.

5. The electronic device of claim 1 , wherein the instructions, when executed by the processor, cause the electronic device to determine, as the ranging device, a first external electronic device having a largest number of used channels or associated with a channel with a lowest noise level among the ones of the plurality of external electronic devices.

6. The electronic device of claim 1 ,
wherein the instructions, when executed by the processor, cause the electronic device to receive state information from the plurality of external electronic devices using the first communication circuit,
wherein the state information includes a battery state and/or a user setting.

7. The electronic device of claim 6 , wherein the instructions, when executed by the processor, cause the electronic device to determine the ranging device by comparing the communication quality between the ones of the plurality of external electronic devices with the battery state higher than a specified charge amount.

8. The electronic device of claim 6 , wherein the instructions, when executed by the processor, cause the electronic device to determine the ranging device by comparing the communication quality between the ones of the plurality of external electronic devices with the user setting for allowing UWB ranging.

9. The electronic device of claim 1 , wherein the instructions, when executed by the processor, cause the electronic device to identify the ones of the plurality of external electronic devices based on group information stored in the memory and the received identifier.

10. The electronic device of claim 9 , wherein the instructions, when executed by the processor, cause the electronic device to:
identify a number of the plurality of external electronic devices based on the one or more response signals;
identify external electronic devices having identical identifiers as the ones of the plurality of external electronic devices when the number of the plurality of external electronic devices is at least a specified number; and
identify the external electronic devices associated with the same account as the ones of the plurality of external electronic devices using the group information when the number of the plurality of external electronic devices is less than the specified number.

11. The electronic device of claim 1 , wherein identifying accounts associated with each one of the plurality of external electronic devices comprises determining a user account associated with at least one of the plurality of external electronic devices that is different from the same account as the electronic device.

12. A method for ultra-wideband (UWB) communication of an electronic device, comprising:
transmitting an advertising signal based on a Bluetooth protocol;
establishing a Bluetooth connection, that is based on the Bluetooth protocol, with each of a plurality of external electronic devices based on one or more response signals for the advertising signal;
receiving identifiers from each of the plurality of external electronic devices over the Bluetooth connection;
accessing a database using the received identifiers from each of the plurality of external electronic devices to identifying accounts associated with each one of the plurality of external electronic devices and determine which ones of the plurality of external electronic devices are associated with a same account as the electronic device;
determining a ranging device among the one of the plurality of external electronic devices based on communication quality related to the plurality of external electronic devices;
releasing connections with the plurality of external electronic devices other than the ranging device; and performing exclusive UWB ranging with the determined ranging device based on a UWB protocol.

13. The method of claim 12 , wherein the determining of the ranging device further comprises determining, as the ranging device, a first external electronic device having highest communication quality among the ones of the plurality of external electronic devices.

14. The method of claim 12 , wherein the determining of the ranging device further comprises determining, as the ranging device, a device having highest reception sensitivity or highest reception strength among the ones of the plurality of external electronic devices.

15. The method of claim 12 , wherein the determining of the ranging device further comprises determining, as the ranging device, a device having a lowest error rate among the ones of the plurality of external electronic devices.

16. The method of claim 12 , wherein the determining of the ranging device further comprises determining, as the ranging device, a device having a largest number of used channels or associated with a channel with a lowest noise level among the ones of the plurality of external electronic devices.

17. The method of claim 12 , further comprising:
receiving state information from the plurality of external electronic devices based on the Bluetooth protocol,
