[0026] Next, the embodiments of this specification will be described in detail.

[0027] The following will be combined with Figure 1 Describe the system architecture to which the channel adjustment method and device of the embodiments of this specification can be applied. It should be noted that Figure 1 What is shown is only an example of the system architecture to which the embodiments of this specification can be applied, to help those skilled in the art understand the technical content of this specification, but it does not mean that the embodiments of this specification cannot be used in other devices, systems, environments or scenarios.

[0028] Figure 1 It is a schematic diagram of the system architecture shown in accordance with an exemplary embodiment of this specification.

[0029] As Figure 1 shown, the system architecture may include, for example, a terminal device and an access point AP.

[0030] The terminal device can be various electronic devices with wireless communication functions, including but not limited to smart phones, tablet computers, laptop portable computers, desktop computers, and so on.

[0031] The AP can be used to provide a bridging function for wireless users to the WLAN (Wireless Local Area Network), and perform wireless-to-wired and wired-to-wireless frame conversion between the terminal device and the WLAN.

[0032] The channel adjustment method provided in the embodiments of this specification will be described in detail below. As Figure 2 shown, Figure 2 FIG. is a flowchart of a channel adjustment method shown according to an exemplary embodiment of this specification. This method can be applied to the AP, for example. The channel adjustment method provided in the embodiments of this specification may include the following steps.

[0033] In step 210, determine whether the AP meets the channel interference detection condition. If it is determined that the AP meets the channel interference detection condition, then execute step 220. If it is determined that the AP does not meet the channel interference detection condition, then execute step 240.

[0034] According to the embodiments of this specification, the channel interference detection condition can be used to determine whether the AP can timely feedback the interference situation of the working channel. Exemplarily, in this embodiment, the channel interference detection condition may include, for example, that the scanning period of the AP is less than the period threshold and the historical scanning result contains channel interference information. Based on this, the scanning period and the historical scanning result corresponding to each sub-channel under the working bandwidth can be obtained. Detect whether the scanning period is less than the period threshold and whether the historical scanning result contains channel interference information. If the scanning period is less than the period threshold and the historical scanning result contains channel interference information, it is determined that the AP meets the channel interference detection condition. Otherwise, it is determined that the AP does not meet the channel interference detection condition. The channel interference information refers to various information that can indicate channel interference, such as signal strength, channel occupancy information, interference source information, etc. The period threshold can be set according to actual needs.

[0035] In step 220, detect whether each sub-channel under the working bandwidth is interfered.

[0036] According to the embodiments of this specification, for example, channel scanning can be performed on each sub-channel to obtain the channel information of each sub-channel. Then, according to the channel information of each sub-channel, it can be determined whether each sub-channel is interfered.

[0037] Channel information may include, for example, at least one of channel occupancy information, signal strength, and interference source information. If the channel occupancy information of a sub-channel indicates that the sub-channel is occupied by other devices, it can be determined that the sub-channel is interfered with. If the signal strength of a sub-channel is less than the strength threshold, it can be determined that the sub-channel is interfered with. If the interference source information of a sub-channel contains at least one interference source, it can be determined that the sub-channel is interfered with. Interference sources may include, for example, other Wi-Fi networks, Bluetooth devices, microwave ovens, wireless cameras, etc. The strength threshold can be set according to actual needs.

[0038] In step 230, if at least one sub-channel in the operating bandwidth is detected to be interfered with, a punching operation is performed on the at least one sub-channel.

[0039] According to an embodiment of the present specification, the punched sub-channel is set to be unavailable. When data needs to be transmitted, the unpunched sub-channels in the operating bandwidth can be used to transmit the data to be transmitted.

[0040] In step 240, determine the priority corresponding to the data to be transmitted.

[0041] According to an embodiment of the present specification, for example, the service information and / or terminal information corresponding to the data to be transmitted can be obtained. Then, based on the service information and / or terminal information, the priority of the data to be transmitted is determined. The service information can be used to represent the service to which the data to be transmitted belongs. The terminal information can be used to represent the terminal that sends or receives the data to be transmitted.

[0042] In step 250, if the priority is higher than the priority threshold, a punching operation is performed on the edge sub-channels in the operating bandwidth.

[0043] According to an embodiment of the present specification, the priority threshold can be set according to actual needs.

[0044] According to an embodiment of the present specification, the edge sub-channel refers to the channel located at the edge of the frequency band. Exemplarily, in this embodiment, the edge sub-channel may include, for example, the sub-channel close to the upper boundary of the frequency band and / or the sub-channel close to the lower boundary of the operating bandwidth. For example, if the operating bandwidth of the AP is 80MHZ and the AP occupies channels 36, 40, 44, and 48, based on this, the edge sub-channels may include channel 36 and channel 48.

[0045] According to an embodiment of the present specification, the punched edge sub-channel is set to be unavailable. When data needs to be transmitted, the unpunched sub-channels in the operating bandwidth can be used to transmit the data to be transmitted.

[0046] According to the embodiments of this specification, when the AP does not meet the channel interference detection condition, selecting to punch holes in some or all of the edge sub-channels can improve the anti-interference ability, and thus improve the transmission reliability of high-priority data.

[0047] In addition, when there is interference in the edge sub-channel but the AP cannot detect it, compared with the traditional dynamic bandwidth adjustment technology, the channel adjustment method of the embodiments of this specification can make better use of the transmission bandwidth and improve the utilization rate of spectrum resources.

[0048] Optionally, after performing the punching operation on at least one sub-channel, it is possible to detect whether the interference received by the at least one sub-channel has disappeared. If it is detected that the interference received by the target sub-channel in the at least one sub-channel has disappeared, a punching recovery operation is performed on the target sub-channel to restore the target sub-channel to an available state.

[0049] Optionally, after performing the punching operation on the edge sub-channels in the working bandwidth, the sub-channels that are not punched in the working bandwidth can be used to transmit the data to be transmitted. After the transmission of the data to be transmitted is completed, the priority of the next data to be transmitted of the data to be transmitted can be determined. If the priority of the next data to be transmitted is less than or equal to the priority threshold, a punching recovery operation is performed on the edge sub-channels to restore the edge sub-channels to an available state.

[0050] Optionally, the punching operation on the sub-channel can be performed by the Preamble Puncture technology. Based on this, the sub-channels that are not punched can be bundled together for use, thereby fully improving the bandwidth utilization rate.

[0051] Optionally, the services can be divided into multiple priorities. For example, the services can be divided into low-priority services and high-priority services. If the service information indicates that the current service is a high-priority service, a punching operation is performed on the edge sub-channels in the working bandwidth. If the service information indicates that the current service is a low-priority service, no punching operation is performed on the edge sub-channels.

[0052] Optionally, the terminal devices can be divided into multiple priorities. For example, the terminal devices can be divided into VIP (Very Important Person) terminals and ordinary terminals, and the priority of the VIP terminals is higher than that of the ordinary terminals. If the terminal information indicates that the terminal is a VIP terminal, a punching operation is performed on the edge sub-channels in the working bandwidth. If the terminal information indicates that the terminal is an ordinary terminal, no punching operation is performed on the edge sub-channels.

[0053] As Figure 3 shown, it is a flowchart of another channel adjustment method shown according to an exemplary embodiment. The method may include the following steps:

[0054] In step 310, the AP evaluates whether it meets the channel interference detection condition. If the AP meets the channel interference detection condition, step 320 is executed. If the AP does not meet the channel interference detection condition, step 360 is executed.

[0055] According to an embodiment of the present specification, the AP can determine, through evaluation, whether the current scanning technology can provide real-time feedback on the interference situation of the working channel. Exemplarily, in this embodiment, the AP can determine whether it can provide real-time feedback on the interference situation of the current working channel based on the scanning period and the scanning result.

[0056] In step 320, the AP starts scanning to collect channel information in real time.

[0057] According to an embodiment of the present specification, the AP can collect the interference situation of each sub-channel under the current working bandwidth. For example, if the working bandwidth of the AP is 80 MHz and the sub-channels include channel 36, channel 40, channel 44, and channel 48, where channel 36 is the primary channel, based on this, the AP can collect the interference situations of channel 36, channel 40, channel 44, and channel 48 through the scanning technology.

[0058] In step 330, the AP analyzes the collected channel information to detect whether each sub-channel under the current working bandwidth is interfered with.

[0059] The AP determines whether each sub-channel under the current working bandwidth is interfered with. If it is detected that some sub-channels are interfered with, step 340 is executed. If no interference is detected, step 350 is executed.

[0060] In step 340, the sub-channels detected to be interfered with are punched.

[0061] Figure 4 It is a schematic diagram showing the punching of the sub-channels detected to be interfered with according to an exemplary embodiment.

[0062] As Figure 4 shown, the working bandwidth of the AP is 80 MHz, and the sub-channels include channel 36, channel 40, channel 44, and channel 48, where channel 36 is the primary channel. When interference is detected on channel 40, whether it is for high-priority packets and VIP terminals or other low-priority services, the detected interfered channel 40 is punched.

[0063] In step 350, the sub-channels are not punched.

[0064] In step 360, the AP analyzes the service information and terminal information corresponding to the data to be transmitted currently to determine whether the current service is a high-priority service and whether the terminal is a VIP terminal. If at least one of the two conditions that the service is a high-priority service and the terminal is a VIP terminal is satisfied, step 370 is executed. If the service is not a high-priority service and the terminal is not a VIP terminal, step 380 is executed.

[0065] In step 370, punch holes in the edge subchannels.

[0066] Figure 5 FIG. is a schematic diagram of punching holes in edge subchannels shown according to an exemplary embodiment.

[0067] As Figure 5 shown, the working bandwidth of the AP is 80MHZ, and the subchannels include channel 36, channel 40, channel 44, and channel 48, where channel 36 is the main channel. For high-priority packets and VIP terminals, holes can be punched in the edge channel 48. For other low-priority services, no punching is performed, and the channels are freely competed for.

[0068] In step 380, do not punch holes in the subchannels.

[0069] Corresponding to the embodiments of the foregoing method, the present specification also provides embodiments of a channel adjustment device and a terminal to which it is applied.
