Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a Wi-Fi channel switching method and an AP device.
Background
Wi-fi (wireless fidelity) technology is a wireless lan technology based on IEEE 802.11b standard, and is widely used for data transmission. Wi-Fi network segments defined in the IEEE 802.11 standard are usually in an Industrial Scientific Medical (ISM) frequency band, and since the ISM frequency band does not need to be authorized during use, Wi-Fi devices in the actual environment are more and more, and the mutual interference is more and more serious.
In the related art, a CSMA/CA (carrier sense multiple access with collision) carrier sense multiple access/collision avoidance mechanism is generally adopted in a standard Wi-Fi technology, so that when a plurality of Wi-Fi hotspot devices exist in the same channel at the same time in a certain range and need to communicate, the CSMA/CA mechanism only allows one of the hotspot devices to perform signal transmission. Therefore, when Wi-Fi is used to transmit video signals in a place with more hotspot devices, video jamming or disconnection often occurs. In addition, the currently used Wi-Fi signal has a frequency band of 2.4GHz and a bandwidth of 20/40MHz, and the channel-to-channel spacing is usually 5MHz, which causes overlapping between adjacent or alternate channels, thereby causing interference to data transmission in the channels, and causing information retransmission when the error rate is high to a certain extent.
In a video monitoring scene using Wi-Fi communication, a Wi-Fi channel between an AP (access point) device of Wi-Fi and a user device is easily affected by other devices using the Wi-Fi channel, or other channels adjacent to or alternate with the Wi-Fi channel, thereby causing video transmission jam or video drop.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The inventor finds that, in the related art, an AP (access point) device mainly selects a working channel in the following two ways:
firstly, when the AP equipment is started, the Wi-Fi channel in the environment is searched, the Wi-Fi channel with the minimum interference is selected as a working channel, and then the Wi-Fi channel is always in the working channel.
Secondly, when the AP equipment is started, the Wi-Fi channel with the minimum interference is selected as a working channel, interference data information in the working channel is scanned at intervals in the working process, whether the working channel has larger interference or not is judged, and if the working channel has larger interference, the working channel is switched to other channels with smaller interference.
In the first mode, since the wireless communication device always operates on one Wi-Fi channel, when the interference in the Wi-Fi channel is large, the user equipment in the Wi-Fi channel may have a problem of disconnection or data transmission jam.
In the second mode, the AP device generally has two working modes, a hotspot mode and a non-hotspot mode, and when the AP device scans, it needs to switch to the non-hotspot mode, and at this time, a hotspot function cannot be provided for the user device in the channel. In other words, when the AP device scans, it may cause the ue to disconnect. Therefore, the AP device cannot perform scanning frequently, but only at intervals of a certain time length. For this reason, and the resource consumption of the AP device by scanning, the interval duration of scanning cannot be set too short, typically between 45 minutes and 120 minutes. If the working channel of the AP device has large interference within the interval duration, channel switching cannot be performed in time, thereby causing a problem that the user device in the working channel is disconnected or data transmission is stuck.
In view of the foregoing problems, embodiments of the present application provide a Wi-Fi channel switching method and AP device, which are described in detail as follows.
As shown in fig. 1, which is a block schematic diagram of an AP device 10 according to an embodiment of the present application, the AP device 10 includes a hotspot component 11 and a hotspot scanning component 12, which are communicatively connected to each other. The hotspot component 11 is configured to provide a wireless hotspot function, and may be accessed by a user device such as an intelligent terminal (e.g., a mobile phone, a notebook computer, etc.), a wireless IPC (internet protocol camera), etc. The hotspot scanning component 12 is configured to scan the number of AP devices, the signal strength of the AP devices, the traffic size of the AP devices, the number of user devices, the signal strength of the user devices, and the like in each Wi-Fi channel in the environment.
In a first embodiment, hotspot component 11 and hotspot scanning component 12 may be hardware Wi-Fi modules with their own processors.
In a second embodiment, as shown in fig. 2, for example, the AP device 10 may include a processor 101, and a first Wi-Fi client 102 and a second Wi-Fi client 103 electrically connected to the processor 101, respectively. The processor 101 may be an MCU (micro controller unit) or a CPU (central processing unit), which is not limited in this embodiment. The first Wi-Fi client 102 and the second Wi-Fi client 103 are hardware modules that can provide Wi-Fi hotspot functionality.
In this embodiment, the first Wi-Fi client 102 and the processor 101 may collectively act as a hotspot component 11, and the second Wi-Fi client 103 and the processor 101 may collectively act as a hotspot scanning component 12.
Fig. 3 is a schematic flowchart of a Wi-Fi channel switching method provided in this embodiment, and the method is applied to the AP device 10 in the first specific implementation described above. The various steps involved in the method are described below.
Step S31, when the hotspot scanning component 12 switches to the first Wi-Fi channel, the hotspot scanning component 12 scans the interference data information of the first Wi-Fi channel in real time.
Wherein the first Wi-Fi channel refers to an operating channel of a hotspot component.
In this embodiment, when the AP device 10 starts up, the hotspot component 11 may search Wi-Fi channels in the environment, and select a Wi-Fi channel with the least interference from the searched Wi-Fi channels as the first Wi-Fi channel. Optionally, the hotspot component 11 may determine the interference level of each Wi-Fi channel according to one or more of the number of AP devices in each searched Wi-Fi channel, the signal strength of the AP device, the traffic level of the AP device, the number of user devices, the signal strength of the user devices, and the like, which is not limited in this embodiment.
In this embodiment, since the hotspot component 11 and the hotspot scanning component 12 of the AP device 10 each have a processor, when the hotspot component 11 of the AP device 10 switches to the first Wi-Fi channel, a first notification may be sent to the hotspot scanning component 12 to notify the hotspot scanning component 12 to start monitoring the first Wi-Fi channel. Wherein the first notification includes a channel identification of the first Wi-Fi channel. In this way, when the hotspot scanning component 12 receives the first notification, the interference data information of the first Wi-Fi channel indicated by the channel identifier in the first notification can be scanned.
The interference data information may include the number of AP devices in a Wi-Fi channel, the signal strength of the AP devices, the traffic size of the AP devices, the number of user devices, the signal strength of the user devices, and the like, where the user device in the Wi-Fi channel refers to a user device connected to the AP device in the Wi-Fi channel.
Step S32, if the scanned interference data information of the first Wi-Fi channel meets a preset condition, the hotspot scanning component 12 selects a new Wi-Fi channel for the hotspot component, so that the hotspot component 11 is switched from the first Wi-Fi channel to the new Wi-Fi channel.
The preset condition can be flexibly set according to actual requirements, for example, the preset condition may be: the number of user equipments in the first Wi-Fi channel is 10. Then, when the hotspot scanning component 12 determines that the number of user devices in the first Wi-Fi channel reaches 10 according to the scanned interference data information, channel switching is required, so as to start selecting a new Wi-Fi channel for the hotspot component 11.
It should be noted that the preset condition may be only a specific value of one of the above interference data information, such as a preset number of AP devices, a preset number of user devices, a preset signal strength of an AP device, and the like; the number of the AP devices may be a predetermined number, and the signal strength of the AP device may be a predetermined strength. The present embodiment does not limit this.
Optionally, in this embodiment, step S32 may include the sub-step shown in fig. 4, so as to select a new Wi-Fi channel through the sub-step hotspot component.
Step S41, the hotspot scanning component 12 obtains interference data information of at least two Wi-Fi channels in the environment obtained by scanning, where the at least two Wi-Fi channels include the first Wi-Fi channel and at least one second Wi-Fi channel.
Wherein, since the environment of the hotspot scanning component 12 is the same as the environment of the hotspot component 11, the hotspot scanning component 12 can scan the interference data information of the working channel (i.e. the first Wi-Fi channel) where the hotspot component 11 is located. Wherein the at least one second Wi-Fi channel refers to other Wi-Fi channels in the environment in which the hotspot scanning component 12 (or the hotspot component 11) is located than the first Wi-Fi channel.
Optionally, in an embodiment, the interference data information of the at least two Wi-Fi channels may be obtained by scanning when the interference data information of the first Wi-Fi channel meets the preset condition. In another embodiment, the hotspot scanning component 12 may always scan interference data information of each Wi-Fi channel in the environment, and only monitor the interference data information of the first Wi-Fi channel when the hotspot component 11 switches to the first Wi-Fi channel. And when the interference data information of the first Wi-Fi channel reaches the preset condition, monitoring the interference data information of other Wi-Fi channels (namely, the at least one second Wi-Fi channel).
Step S42, according to the interference data information of the at least one second Wi-Fi channel, selecting a second Wi-Fi channel with the minimum interference from the at least one second Wi-Fi channel as the new Wi-Fi channel.
Wherein, step S42 may include the sub-steps as shown in fig. 5:
step S51, performing weighted summation on the number of AP devices, the signal strength of the AP devices, the traffic size of the AP devices, the number of user devices, and the signal strength of the user devices in the second Wi-Fi channel to obtain a sum.
In practice, step S41 is performed for each second Wi-Fi channel, so as to obtain a sum value corresponding to the second Wi-Fi channel, and thus the number of obtained sum values is consistent with the number of second Wi-Fi channels. For example, when there are 2 second Wi-Fi channels, the sum values obtained are 2, and the 2 sum values correspond to the 2 second Wi-Fi channels, respectively. For another example, when there are 5 second Wi-Fi channels, the sum values obtained are 5, and the 5 sum values respectively correspond to the 5 second Wi-Fi channels.
Step S52, determining a minimum sum value from the sum values of the at least one second Wi-Fi channel, and using the second Wi-Fi channel corresponding to the minimum sum value as the new Wi-Fi channel.
Optionally, in this embodiment, step S22 may further include the following sub-step, so as to enable the hotspot component to switch from the first Wi-Fi channel to the new Wi-Fi channel through this sub-step:
the hotspot scanning component 12 sends a second notification to the hotspot component 11, where the second notification includes the channel identifier of the new Wi-Fi channel.
In this case, the Wi-Fi channel switching method provided in this embodiment may further include:
the hotspot component 11, upon receiving the second notification, switches from the first Wi-Fi channel currently located to the new Wi-Fi channel indicated by the channel identification in the second notification.
Through the above process, the hot spot scanning component 12 in the AP device can scan, and the hot spot function can still be provided through the hot spot component 11 during scanning, so that the AP device 10 can monitor the working channel and each channel in the environment in real time, and thus, when the interference of the working channel is large, a new channel can be selected in time for switching.

Step S61, when controlling the first Wi-Fi client 102 to switch to the first Wi-Fi channel, controlling the second Wi-Fi client 103 to scan the interference data information of the first Wi-Fi channel in real time.
In this embodiment, the processor 101 may control the first Wi-Fi client 102 to search for a Wi-Fi channel in an environment where the first Wi-Fi client 102 is located when the first Wi-Fi client 102 is started, select a Wi-Fi channel with the least interference as the first Wi-Fi channel, and control the first Wi-Fi client 102 to switch to the first Wi-Fi channel.
