Abstract

Provided is an electronic device including a communication module configured to exchange data with an external device, in which the communication module includes a first core and a second core, a memory storing instructions, and a processor configured to execute the instructions to determine first channels to be scanned by the first core and second channels to be scanned by the second core, scan the first channels by using the first core, scan the second channels by using the second core, determine third channels to be scanned by the first core and fourth channels to be scanned by the second core, based on a non-PSC detected based on at least one of the first channels and the second channels, scan the third channels by using the first core, and scan the fourth channels by using the second core.

First claim

What is claimed is:

1. An electronic device comprising:
a communication module configured to perform data communications with an external device, wherein the communication module comprises a first core and a second core;
a memory storing instructions; and
at least one processor configured to execute the instructions to:
determine first channels to be scanned by the first core and second channels to be scanned by the second core,
scan the first channels by using the first core for a first time,
scan the second channels by using the second core for a second time,
determine third channels to be scanned by the first core and fourth channels to be scanned by the second core, based on a non-preferred scanning channel (PSC) detected based on at least one of the first channels and the second channels,
scan the third channels by using the first core for a third time after the first time, and
scan the fourth channels by using the second core for a fourth time after the second time.

2. The electronic device of claim 1 , wherein the at least one processor comprises a communication processor included in the communication module or an application processor.

3. The electronic device of claim 1 , wherein the first channels comprise at least one channel in a 2.4 GHz band, and
the second channels comprise at least one channel in a 5 GHz band.

4. The electronic device of claim 3 , wherein the third channels comprise at least one channel in the 5 GHz band, the third channels being different from the second channels, and
the fourth channels comprise at least one PSC in a 6 GHz band.

5. The electronic device of claim 4 , wherein the fourth channels comprise at least one non-PSC in the 6 GHz band.

6. The electronic device of claim 1 , wherein the first time and the second time at least partially overlap each other, and
the third time and the fourth time at least partially overlap each other.

7. The electronic device of claim 1 , wherein the at least one processor is further configured to execute the instructions to determine the first channels and the second channels, based on a preset expected number of non-PSCs.

8. The electronic device of claim 1 , wherein the at least one processor is further configured to execute the instructions to determine the third channels and the fourth channels such that a difference between an end of the third time and an end of the fourth time is minimized.

9. The electronic device of claim 1 , wherein the at least one processor is further configured to execute the instructions to:
determine preliminary third channels to be scanned by the first core and preliminary fourth channels to be scanned by the second core, and
determine the third channels and the fourth channels by adjusting the preliminary third channels and the preliminary fourth channels, based on the number of detected non-PSCs.

10. The electronic device of claim 1 , wherein the at least one processor is further configured to execute the instructions to:
detect an additional non-PSC by scanning the third channels or the fourth channels, and
scan the additional non-PSC by using at least one of the first core and the second core.

11. The electronic device of claim 1 , wherein the electronic device further comprises a mobile communication terminal.

12. A method for scanning channels in frequency bands performed by an electronic device, the method comprising:
determining first channels to be scanned by a first core of a communication module of the electronic device and second channels to be scanned by a second core of the communication module of the electronic device;
scanning the first channels by using the first core for a first time;
scanning the second channels by using the second core for a second time;
determining third channels to be scanned by the first core and fourth channels to be scanned by the second core, based on a non-preferred scanning channel (PSC) detected based on at least one of the first channels and the second channels;
scanning the third channels by using the first core for a third time after the first time; and
scanning the fourth channels by using the second core for a fourth time after the second time.

13. The method of claim 12 , wherein the first channels comprise at least one channel in a 2.4 GHz band, and
the second channels comprise at least one channel in a 5 GHz band.

14. The method of claim 13 , wherein the third channels comprise at least one channel in the 5 GHz band, the third channels being different from the second channels, and
the fourth channels comprise at least one PSC in a 6 GHz band.

15. The method of claim 14 , wherein the fourth channels comprise at least one non-PSCs in the 6 GHz band.

16. The method of claim 12 , wherein the first time and the second time at least partially overlap each other, and
the third time and the fourth time at least partially overlap each other.

17. The method of claim 12 , wherein the determining the first channels to be scanned by the first core and the second channels to be scanned by the second core comprises determining the first channels and the second channels, based on a preset expected number of non-PSCs.

18. The method of claim 12 , wherein the determining the third channels to be scanned by the first core and the fourth channels to be scanned by the second core comprises determining the third channels and the fourth channels such that a difference between an end of the third time and an end of the fourth time is minimized.

19. The method of claim 12 , further comprising:
detecting an additional non-PSC by scanning the third channels or the fourth channels; and
scanning the additional non-PSC by using at least one of the first core and the second core.

20. An electronic device comprising:
a communication module configured to perform data communications with an external device, wherein the communication module comprises a first core and a second core;
a memory storing instructions; and
at least one processor configured to execute the instructions to:
determine at least one target frequency band available to the electronic device, based on a geographic region of the electronic device,
determine channels available in the at least one target frequency band;
based on a preset frequency band not being available based on the target frequency band, determine first channels and third channels to be scanned by the first core and second channels to be scanned by the second core;
scan the first channels by using the first core for a first time,
scan the second channels by using the second core for a second time, and
scan the third channels by using the first core for a third time.
