Each of them will be described in detail below.

Please refer to FIG. 1A . FIG. 1A is a schematic flowchart of a network scanning method disclosed in an embodiment of the present invention. Wherein, the network scanning method shown in FIG. 1A may include the following steps:

101. After receiving the operation instruction for network scanning, acquire at least two channels to be scanned.

The embodiment of the present invention is applied to a terminal device with dual antennas. After receiving an operation instruction for network scanning, the terminal device acquires at least two channels to be scanned.

In the embodiment of the present invention, the above-mentioned terminal device may be a smart phone, a smart watch, a handheld computer, a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), a point of sale (Point of Sales, POS), etc. Do not repeat.

As an optional implementation manner, the user may input an operation instruction of network scanning to the terminal device by turning on the WiFi switch of the terminal device. When scanning the WiFi network, scan the multiple channels to be scanned one by one to find the access points that can be accessed in each channel. The above channels to be scanned may be all channels or selected common channels, so that only common channels are scanned so as to quickly obtain an accessible network.

102. The first antenna performs channel scanning on the channel to be scanned according to a preset scanning sequence.

In the embodiment of the present invention, the terminal device has dual antennas, which are a first antenna and a second antenna. The two antennas are independent of each other and perform a channel scanning function respectively, and then combine the scanning results of the two antennas to remove duplicates in the scanning results. A record of scanned access points for final channel scan results.

When performing channel scanning, both active scanning and passive scanning can be performed. Please refer to FIG. 1B . FIG. 1B is a schematic diagram of a terminal device performing active scanning according to an embodiment of the present invention. As shown in FIG. 1B , it is assumed that the terminal device is currently performing channel scanning on the first channel, and thus sends a Request Probe frame on the first channel. After receiving the request frame, the access point AP on the first channel returns to carry the AP. The Response Probe frame (beacon frame) of the SSID of the SSID, if the terminal device still stays on the first channel to perform channel scanning when receiving the beacon frame, the terminal device can discover the AP and know the AP identified by the SSID. can access.

Please refer to FIG. 1C , which is a schematic diagram of a terminal device performing passive scanning according to an embodiment of the present invention.

AP.

By analyzing the above-mentioned active scanning and passive scanning processes, it can be known that when the AP of the target channel sends a beacon frame, the terminal device is not scanning the target channel and cannot find the AP.

103. Determine whether the time after the first antenna starts to perform channel scanning exceeds a preset time threshold.

In this embodiment of the present invention, the first antenna and the second antenna use the same sequence to perform channel scanning on the channels to be scanned, but the two antennas start scanning at different times, and the second antenna is turned on for scanning more than the first antenna is turned on. The scan time delay preset time threshold. For example, both antennas start channel scanning from the first channel, and the scanning time of staying in the first channel is X seconds. When the two antennas cooperate to perform channel scanning, it is equivalent to extending the stay time in the first channel to (X + preset time threshold) seconds, thereby increasing the probability of the AP being discovered on the first channel.

Settings, obtain historical scan records from it, to determine preset common channels or count common channels according to historical scan records; when the second antenna scans a common channel, it can increase the number of scans of the common channel, thereby increasing the number of scans from the common channel. Probability of discovering accessible APs.

As an optional implementation manner, after the channel scan of the second antenna is completed, a list of access points scanned by the first antenna and a list of access points scanned by the second antenna are obtained; The in-point list and the access point list scanned by the second antenna are combined to obtain a channel scan result by removing duplicate access points in the list; then it is judged whether the number of access points in the above-mentioned channel scan result is greater than a preset number threshold; If the number of the access points is less than or equal to the preset number threshold, the preset time threshold is increased to perform the network scan described in steps 101 to 104 again.

As an optional implementation manner, after the channel scanning of the second antenna is completed, the total number of access points scanned by the first antenna and the total number of access points scanned by the second antenna are obtained; The total number of incoming points is subtracted from the total number of access points scanned by the first antenna to obtain the difference between the scanning results of the dual antennas; if the difference between the scanning results of the dual antennas is less than or equal to the preset difference threshold, the preset time is increased threshold to redo the network scan described in steps 101-104.

It can be seen that, by implementing the method described in FIG. 1A , the first antenna and the second antenna of the terminal device can start channel scanning respectively at a certain time interval, thereby prolonging the stay time of a single channel during scanning and improving the reception. Probability of a beacon frame to an access point.

Please refer to FIG. 2A . FIG. 2A is a schematic flowchart of another network scanning method disclosed in an embodiment of the present invention. As shown in Figure 2A, the method may include the following steps:

The above channels to be scanned may be all channels or selected common channels, so that only common channels are scanned so as to quickly obtain an accessible network.

202. The first antenna performs channel scanning on the channels to be scanned according to a preset scanning sequence.

Compared with the case of dual-antenna synchronous scanning, the total channel scanning time is extended by 1/3 of the original time. If the number of channels to be scanned is large, the extension ratio of the total channel scanning time will gradually decrease; suppose there are 10 channels. If the channel needs to be scanned, the total time for channel scanning only needs to be extended by 1/10. On the other hand, the dwell time of each channel is increased from the original X seconds to 2X seconds, so under the same other conditions, the probability of scanning to an AP can be doubled.
