Abstract

A method of dynamic frequency selection includes receiving setting information of a WI-FI unit input by an input unit, controlling the WI-FI unit in a STA working mode to switch different channels to scan an available access point AP with dynamic frequency selection within one channel when receiving the setting information of setting the WI-FI unit to work in an AP working mode and the STA working mode simultaneously, controlling the WI-FI unit in the AP working mode to switch to the channel within which the WI-FI unit in the STA working mode scans the available access point AP when the WI-FI unit in the STA working mode scans the available access point AP, and controlling the WI-FI unit in the AP working mode to communicate with a terminal device via the switched access point AP.

Claims

1. An electronic device with dynamic frequency selection, comprising:

an input unit;

at least one processor coupled to the input unit;

a WI-FI unit coupled to the at least one processor configured to work in an AP working mode and a STA working mode;

a non-transitory storage medium coupled to the at least one processor and configured to store a plurality of instructions, which cause the device to;

receive setting information of the WI-FI unit input by the input unit;

control the WI-FI unit in the STA working mode to switch different channels to scan an available access point AP within one channel when receiving the setting information of setting the WI-FI unit to work in the AP working mode and the STA working mode simultaneously;

when the WI-FI unit in the STA working mode scans the available access point AP, control the WI-FI unit in the STA working mode to communicate with the scanned access point AP via the one channel within which the available access point AP is scanned;

control the WI-FI unit in the AP working mode to switch to the one channel within which the WI-FI unit in the STA working mode scans the available access point AP; and

control the WI-FI unit in the AP working mode to communicate with a terminal device via the one channel within which the WI-FI unit in the STA working mode scans the available access point AP.

2. The electronic device as recited in claim 1, wherein the plurality of instructions are further configured to cause the electronic device to:

detect whether the WI-FI unit in the STA working mode communicates with the access point AP.

3. The electronic device as recited in claim 2, wherein the plurality of instructions are further configured to cause the electronic device to:

when determining the WI-FI unit in the STA working mode fails to communicate with the access point AP, control the WI-FI unit in the STA working mode to switch to another channel to scan one available access point AP.

4. The electronic device as recited in claim 3, wherein the plurality of instructions are further configured to cause the electronic device to:

when the WI-FI unit in the STA working mode scans one available access point AP in a default time, control the WI-FI unit in the STA working mode to communicate with the scanned available access point AP via the channel within which the available access point AP is scanned; and

control the WI-FI unit in the AP working mode to switch to the channel within which the available access point AP is scanned, and control the WI-FI unit in the AP working mode to communicate with the terminal device via the switched channel.

5. The electronic device as recited in claim 2, wherein the plurality of instructions are further configured to cause the electronic device to:

when determining the WI-FI unit in the STA working mode fails to scan one available access point AP in a default time, control the WI-FI unit in the AP working mode to switch to the channel of 2.4 GHz or other NUN-UNII channels.

6. The electronic device as recited in claim 1, wherein the electronic device further comprises a display unit, the plurality of instructions are further configured to cause the electronic device to:

generate a setting interface configured to set the setting information of the WI-FI unit, and display the setting interface on the display unit.

7. The electronic device as recited in claim 1, wherein the plurality of instructions are further configured to cause the device to:

disable the function of the WI-FI unit when receiving setting information of disabling the WI-FI unit.

8. A method of dynamic frequency selection comprises:

receiving setting information of a WI-FI unit input by an input unit;

controlling the WI-FI unit in a STA working mode to switch different channels to scan an available access point AP with dynamic frequency selection within one channel when receiving the setting information of setting the WI-FI unit to work in an AP working mode and the STA working mode simultaneously;

when the WI-FI unit in the STA working mode scans the available access point AP, controlling the WI-FI unit in the STA working mode to communicate with the scanned access point AP via the one channel within which the available access point AP is scanned;

controlling the WI-FI unit in the AP working mode to switch to the one channel within which the WI-FI unit in the STA working mode scans the available access point AP; and

controlling the WI-FI unit in the AP working mode to communicate with a terminal device via the one channel within which the WI-FI unit in the STA working mode scans the available access point AP.

9. The method as recited in claim 8, further comprises:

detecting whether the WI-FI unit in the STA working mode communicates with the access point AP.

10. The method as recited in claim 9, further comprises:

when determining the WI-FI unit in the STA working mode fails to communicate with the access point AP, controlling the WI-FI unit in the STA working mode to switch to another channel to scan one available access point AP.

11. The method as recited in claim 10, further comprises:

when the WI-FI unit in the STA working mode scans one available access point AP in a default time, controlling the WI-FI unit in the STA working mode to communicate with the scanned available access point AP via the channel within which the available access point AP is scanned; and

controlling the WI-FI unit in the AP working mode to switch to the channel within which the available access point AP is scanned, and controlling the WI-FI unit in the AP working mode to communicate with the terminal device via the switched channel.

12. The method as recited in claim 9, further comprises:

when determining the WI-FI unit in the STA working mode fails to scan one available access point AP in a default time, controlling the WI-FI unit in the AP working mode to switch to the channel of 2.4 GHz or other NUN-UNII channels.

13. The method as recited in claim 8, further comprises:

generate a setting interface configured to set the setting information of the WI-FI unit, and display the setting interface on a display unit.

14. The method as recited in claim 8, further comprises:

disabling the function of the WI-FI unit when receiving setting information of disabling the WI-FI unit.
