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 (42)

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.
