In the current application scenario, when an Access Point (AP) of multiple vendors is deployed in the same scenario, typically, the APs of multiple vendors may select channels in a (1, 6, 11) channel combination, so when the APs of multiple vendors currently selecting channels in the (1, 6, 11) channel combination generate interference, an automatic channel adjustment algorithm is typically used to adjust channels of each AP, that is, a channel processing method under co-channel interference.
However, there is currently little channel adjustment method for the case of adjacent channel interference generated by different vendors of APs whose operating channels belong to different orthogonal channel combinations.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It is to be noted that unless otherwise defined, technical or scientific terms used herein should be taken in a general sense as understood by one of ordinary skill in the art to which the present invention belongs. The terms "first," "second," and the like, as used herein, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
For the sake of understanding, the inventive concept of the present invention will be first described.
As shown in fig. 1, the frequency bandwidth of the WLAN 2.4G frequency band is from 2.4GHz to 2.483GHz, and there are a total of 83MHz, and 14 channels, which are channel 1, channel 2, channel 3, channel 4, channel 5, channel 6, channel 7, channel 8, channel 9, channel 10, channel 11, channel 12, channel 13, and channel 14, respectively; taking the channel 1 and the channel 2 as examples, the frequency point corresponding to the channel 1 is 2.412GHz, the frequency point corresponding to the channel 2 is 2.417GHz, the effective bandwidth of each channel is 22MHz, adjacent channels in the channels 1 to 13 are 5MHz apart, and a plurality of channels have overlapping parts. However, as can be seen in conjunction with fig. 1, the 2.4G band has a total of 4 sets of orthogonal channel combinations that do not interfere with each other: (1, 6, 11), (2, 7, 12), (3, 8, 13), (4, 9, 14). It will be appreciated that where (1, 6, 11) represents an orthogonal channel combination of channel 1, channel 6, channel 11.
Currently, the (1, 6, 11) combination among the 2.4G band orthogonal channel combinations is commonly used. Moreover, when multiple vendor types of APs are deployed in the same scene, channels in the same channel combination, for example, channels in (1, 6, 11) channel combinations are generally selected, so most 2.4G frequency band automatic channel adjustment algorithms are corresponding processing methods for APs of different vendor types operating in the same orthogonal channel combination, i.e., co-channel interference, while almost no working channels for APs of different vendor types belong to different orthogonal channel combinations, i.e., corresponding processing methods for APs of different vendor types operating in adjacent channel interference. In the invention, the manufacturer type of the AP can be used for indicating the factory information of the corresponding AP. For example, in the prior art, for the case that APs of different vendor types operate on the same orthogonal channel combination, a negotiation can be performed through carrier sense multiple access with collision avoidance (Carrier sense multiple mccess with collision avoid, CSMA/CA), so as to avoid collision; AP1 uses (1, 6, 11) channel combinations and other types of AP2 use other channel combinations, such as (3, 8, 13), with channel spectrum overlap with (1, 6, 11); since the working channels of APs of different vendor types belong to different orthogonal channel combinations, the interference generated belongs to adjacent channel interference. The adjacent channel interference may not avoid collisions through carrier sense multiple access CSMA/CA coordination with collision avoidance, is more severe than co-channel interference, and may not provide better quality wireless service than operating on the same orthogonal channel combination. The principle of adjacent channel interference is further described for ease of understanding. For example, if the (1, 6, 11) channel combination is adopted by the AP1, and the (3, 8, 13) channel combination is adopted by the other types of APs 2, the AP1 transmits the frame data by using the channel 1, and at the same time, since the channel 1 and the channel 3 have the near-1 half-channel spectrum overlapping, the AP2 may not know in time that the AP1 is transmitting the frame data by using the channel 1, and therefore the AP2 is transmitting the frame data by using the channel 3, so that collision packet loss occurs between the frame data transmitted by using the channel 3 and the frame data transmitted by using the channel 1, thereby generating the adjacent channel interference.
In view of this, the present invention proposes a channel adjustment method, which determines, based on listening data of a first AP, a working channel set of a second AP belonging to a different vendor type with the first AP, and adjusts orthogonal channel combinations of the first AP according to an orthogonal channel combination list corresponding to the working channel set of the second AP and a first total number of second APs corresponding to each orthogonal channel combination in the orthogonal channel combination list, so that working channels of all APs belong to the same orthogonal channel combination, thereby realizing reduction of adjacent channel interference.
The channel adjustment method and apparatus of the present invention are described below with reference to the accompanying drawings.
FIG. 2 is a diagram of an implementation environment of a channel adjustment method including a control device according to one embodimentPreparation method210. A first AP220 and a second AP230 satisfying a preset condition. The first AP220 may be understood as an AP whose working channel is to be adjusted, and the first AP220 may be configured to monitor frame data of a neighboring AP on a current working channel and send the monitored frame data to the control device. The second AP230 may be understood as an AP deployed in the same application scenario as the first AP, and belonging to a different vendor type from the first AP. The control device 210 is configured to receive listening data from the first AP; determining the number of second APs and corresponding working channel information thereof based on the monitoring data; and indicating the first AP based on the number of the second APs and the corresponding channel information, and enabling the first AP to adjust the working channel of the first AP.
The control device 210 shown in fig. 2 may be an Access Controller (AC), or may be a cloud platform deployed in a wireless network.
Fig. 3 is a flowchart of a channel adjustment method according to an embodiment of the present application, where the method may be performed by a control device, and the control device may be as shown in fig. 2. As shown in fig. 3, the method includes:
in step 310, listening data from a first AP is received.
The monitoring data from the first AP is frame data of neighbor APs monitored by the first AP in a current working channel. It will be appreciated that the process of receiving listening data from the first AP may refer to the prior art, and will not be described herein for brevity.
Step 320, determining a working channel set corresponding to a second AP when determining, based on the listening data, that the listening data includes the second AP satisfying a preset condition; the second AP is different from the manufacturer type corresponding to the first AP, the second AP is a neighbor AP of the first AP, and the working channel corresponding to the first AP belongs to a first orthogonal channel combination.
The working channel set corresponding to the second AP is a set formed by working channels of the second AP. The working channel of each second AP is the working channel corresponding to the second AP in the monitoring time period corresponding to the monitoring data. It may be understood that the listening data includes an operating channel identifier of an AP, so that a set of operating channels corresponding to the second APs that satisfy the preset condition may be determined based on the operating channel identifiers of the second APs in the listening data.
It is also understood that the first AP and the second AP belong to different vendors. Specifically, the vendor type of the AP may be determined based on the device identification information of the AP. The device identification information is used to distinguish identities of the APs, and may be used to distinguish vendors of the APs. The device identification information may be, for example, a media access control (Media access control, MAC) identification.
And combining the above, wherein the monitoring data is frame data of neighbor APs monitored by the first AP in the current working channel. And, since the frame data of the AP generally includes the operating channel identification of the AP and the device identification information of the AP. The device identification information can be used to distinguish whether the monitored neighboring AP and the first AP belong to the same vendor type, so that it can be used to determine whether the monitored neighboring AP is the second AP; the operating channel identification may be used to identify the operating channel of the AP. Thus, based on the listening data, the second AP and its corresponding operating channel may be determined.
In addition, in the case that the working channel set corresponding to the second AP and the working channel of the first AP are in the same orthogonal channel combination, the processing method for the same-frequency interference can be based on the existing processing method. And for the case that the working channel corresponding to the second AP and the working channel of the first AP are in different orthogonal channel combinations, the adjacent channel interference needs to be processed. In the invention, the processing of the adjacent channel interference is realized mainly by adjusting the orthogonal channel combination corresponding to the first AP. Specifically, the process of processing the adjacent channel interference may refer to steps 330 to 350.
Step 330, determining a list of orthogonal channel combinations corresponding to the working channel set, and a first total number of second APs corresponding to each of the orthogonal channel combinations in the list of orthogonal channel combinations.
It may be understood that the monitored neighboring AP may include an AP belonging to the same vendor type as the first AP, or may include an AP belonging to a different vendor type than the first AP (the second AP). And the working channels of each second AP are different, the corresponding working channel sets of the second APs meeting the preset conditions are different, so that the corresponding orthogonal channel lists are different. Thus, from the set of operating channels corresponding to the second AP, a list of orthogonal channel combinations corresponding to the set of operating channels may be determined, and the corresponding list of orthogonal channel combinations may include one or more orthogonal channel combinations.
For ease of understanding, the concept of a list of orthogonal channel combinations corresponding to the set of operating channels corresponding to the second AP and the first total number is illustrated herein. For example, if the second AP included in the listening data has AP2, AP3, and AP4, and the working channels corresponding to AP2, AP3, and AP4 in the listening data are channel 1, channel 6, and channel 11, respectively, the corresponding orthogonal channel combination list is (1, 6, and 11). For another example, if the second AP included in the listening data has AP2, AP3, AP4, AP5, AP6, AP7, and AP8, and the working channels corresponding to AP2, AP3, AP4, AP5, AP6, AP7, and AP8 in the listening data are channel 1, channel 6, channel 11, channel 2, channel 7, channel 12, and channel 1, respectively, the corresponding orthogonal channel combination list includes (1, 6, 11) and (2, 7, and 12) two orthogonal channel combinations, a first total number of the second APs corresponding to the orthogonal channel combinations (1, 6, and 11) in the orthogonal channel combination list is 4, and a first total number of the second APs corresponding to the orthogonal channel combinations (1, 6, and 11) in the orthogonal channel combination list is 3.
It may also be appreciated that adjacent channel interference may be generated when the operating channel corresponding to the second AP is in a different orthogonal channel combination with the operating channel of the first AP. And, since the orthogonal channel combination list corresponding to the working channel set of the second AP satisfying the preset condition may include one or more orthogonal channel combinations, for the case that the orthogonal channel combination list includes one or more orthogonal channel combinations, the case processing may be divided, specifically refer to step 340 or step 350.
Step 340, in the case that the orthogonal channel combinations in the orthogonal channel combination list include only one second orthogonal channel combination, adjusting the first orthogonal channel combination of the first AP to the second orthogonal channel combination, and instructing the first AP to adjust the working channel to the target channel in the second orthogonal channel combination.
As mentioned above, the working channel corresponding to the first AP belongs to the first orthogonal channel combination.
It will be appreciated that to avoid adjacent channel interference due to the operating channels of the first AP belonging to different orthogonal channel combinations with the operating channels of the second AP, the orthogonal channel combinations of the first AP and the second AP may be tuned to identical orthogonal channel combinations. In addition, in the case that the orthogonal channel combination list includes only one orthogonal channel combination, the orthogonal channel combination corresponding to the first AP may be directly adjusted from the original first orthogonal channel combination to the second orthogonal channel combination, and the first AP may be instructed to adjust the working channel to the target channel in the second orthogonal channel combination. Specifically, the working channel of the first AP may be adjusted to the target channel in the second orthogonal channel combination based on the existing CSMA/CA algorithm.
It may be further understood that the orthogonal channel combination list may also include a plurality of orthogonal channel combinations, in which case, it is necessary to further combine the number of second APs corresponding to each of the orthogonal channel combinations in the orthogonal channel combination list, and adjust the orthogonal channel combination of the first AP to the target channel combination with the largest number of second APs corresponding to the orthogonal channel combination in the orthogonal channel combination list, so as to minimize the adjacent channel interference generated between APs of different vendors and operating in different orthogonal channel combinations.
In step 350, when the orthogonal channel combination list includes a plurality of orthogonal channel combinations, the orthogonal channel combination corresponding to the first AP is adjusted to a target channel combination by the first orthogonal channel combination, where the target channel combination is an orthogonal channel combination with the largest first total number of corresponding second APs in the orthogonal channel combination list, and instructs the first AP to adjust the working channel to a target channel in the target channel combination.
It can be appreciated that step 340 reduces adjacent channel interference by adjusting the orthogonal channel combinations corresponding to the first AP to match the orthogonal channel combinations corresponding to the first AP with the orthogonal channel combinations (second orthogonal channel combinations) in the orthogonal channel combination list corresponding to the second AP. Step 350 adjusts the orthogonal channel combinations corresponding to the first AP, so that the orthogonal channel combinations corresponding to the first AP are consistent with the first total maximum number of orthogonal channel combinations (target channel combinations) of the corresponding second APs in the orthogonal channel combination list, thereby reducing adjacent channel interference.
According to the channel adjustment method provided by the invention, the working channel set of the second AP which is adjacent to the first AP and belongs to different manufacturer types is determined based on the monitoring data of the first AP, and the orthogonal channel combination corresponding to the first AP is adjusted according to the orthogonal channel combination list corresponding to the working channel set of the second AP and the first total number of the second APs corresponding to each orthogonal channel combination in the orthogonal channel combination list, so that the orthogonal channel combination corresponding to the first AP is consistent with the unique orthogonal channel combination (second orthogonal channel combination) in the orthogonal channel combination list corresponding to the second APs of other manufacturer types or the orthogonal channel combination (target channel combination) with the largest first total number of the corresponding second APs, thereby reducing adjacent frequency interference generated by the fact that the working channels of the APs of different manufacturer types belong to different orthogonal channel combinations.
It will be appreciated that there may or may not be one or more second APs in the listening data, and in the absence of a second AP, there is no adjacent channel interference, and the prior art may be used to handle co-channel interference between different first APs based on having the orthogonal channel combinations of the first APs remain unchanged.
Accordingly, in one embodiment, the channel adjustment method may further include, corresponding to step 320 above: and under the condition that the second AP meeting the preset condition is not contained based on the monitoring data, the orthogonal channel combination of the first AP is kept unchanged.
The orthogonal channel combination of the first AP may be any one of 4 sets of orthogonal channel combinations (1, 6, 11), (2, 7, 12), (3, 8, 13), (4, 9, 14) in the 2.4G frequency band, which do not interfere with each other.
In one embodiment, as shown in fig. 4, based on the listening data, the determining that the listening data includes the second AP satisfying the preset condition includes the following steps:
step 410, determining, based on the listening data, whether the listening data includes a second AP.
The monitoring data comprises a first identification information set of the AP. The first identification information set of the APs is a set of device identification information corresponding to at least one AP in the listening data. The device identification information of the AP may be a MAC identification.
It can be understood that the device identification information (i.e., the second identification information set) of the AP of the same vendor type as the first AP may be stored in the control device in advance, so that after the control device obtains the monitoring data, the control device may determine whether the monitored neighboring AP belongs to the AP of the same vendor type as the first AP according to the device identification information of the monitored neighboring AP in one-to-one comparison with the device identification information in the second identification information set, and consider that the monitored neighboring AP does not belong to the same vendor type as the first AP if it is determined that the device identification information of the monitored neighboring AP belongs to one device identification information in the second identification information set.
Thus, in one embodiment, this step 410 includes: and determining the AP corresponding to the device identification information outside the second identification information set as a second AP under the condition that the first identification information set contained in the monitoring data contains the device identification information outside the second identification information set. The second identification information set is a device identification information set of the same AP as the first AP manufacturer type.
It can be further understood that by increasing the judgment on whether the second AP exists, the possibility of existence of adjacent channel interference is directly eliminated, which is beneficial to accelerating the channel adjustment speed of the first AP.
In addition, because the adjacent frequency interference corresponding to the second total number of the neighbor APs is smaller when the second total number of the neighbor APs is smaller, the judgment of the second total number of the neighbor APs can be continuously increased, the original orthogonal channel combination corresponding to the first AP can be directly used when the second total number of the neighbor APs is smaller, and the working channel of the first AP is adjusted based on the existing automatic channel adjustment algorithm, so that the channel adjustment speed of the first AP is also facilitated to be accelerated to a certain extent. That is, in the event that it is determined that the second total number of neighbor APs is less than the first preset threshold, the orthogonal channel combination of the first AP is maintained unchanged. Thus, following step 410, step 420 may also be included.
Step 420, in case it is determined that the listening data includes a second AP, determining a second total number of neighbor APs.
Wherein, the neighbor AP may correspond to the monitored neighbor AP in the foregoing.
Specifically, the second total number of neighbor APs is the number of neighbor APs included in the listening data, including the sum of the number of second APs and APs of the same vendor type as the first AP.
It may be appreciated that when it is determined that the second total number of neighboring APs is greater, in order to further determine whether it is necessary to adjust the orthogonal channel combination of the first AP, to reduce the adjacent channel interference, it may be further determined whether the adjacent channel interference is serious based on the third total number of the second AP, thereby determining whether to adjust the orthogonal channel combination corresponding to the first AP. The original orthogonal channel combination corresponding to the first AP can be directly used when the number of the second APs in the neighbor APs is small, and the working channel of the first AP is adjusted based on the existing automatic channel adjustment algorithm, so that the channel adjustment speed of the first AP is also beneficial to accelerating to a certain extent. Thus, after step 420, step 430 and step 440 may also be included.
Step 430, determining a third total number of second APs in the neighbor APs if the second total number of neighbor APs is determined to be greater than or equal to the first preset threshold.
Specifically, the determining process of the third total number of the second APs may refer to the above-described determining process of whether the second APs are included, and after determining that one AP in the listening data is the second AP, the number of the second APs may be increased by 1, thereby determining the third total number of the second APs included in the listening data.
It can be appreciated that when it is determined that the second total number of the neighboring APs is greater, in order to further determine whether it is necessary to adjust the orthogonal channel combination of the first AP, it may be further determined whether the adjacent channel interference is serious based on the third total number of the second APs, so as to determine that the neighboring APs include the second AP that satisfies the preset condition, thereby facilitating a subsequent further determination of whether to adjust the orthogonal channel combination corresponding to the first AP. When the number of the second APs is small, the original orthogonal channel combination corresponding to the first AP can be directly used, and the working channel of the first AP is adjusted based on the existing automatic channel adjustment algorithm, so that the channel adjustment speed of the first AP is also improved to a certain extent. Thus, in one embodiment, step 440 is also included after step 430.
Step 440, determining that the neighboring APs include the second AP satisfying the preset condition if the third total number of the second APs in the neighboring APs is greater than or equal to the second preset threshold.
In addition, the second AP corresponds to one or more, and thus, the second AP may also have one or more operating channels. Therefore, when the third total number of the second APs in the neighbor APs is larger, the corresponding orthogonal channel combinations can be conveniently determined based on the working channel sets of the second APs in the neighbor APs by determining the working channel sets of the second APs in the neighbor APs, so that the orthogonal channel combinations corresponding to the first AP are further adjusted to be consistent with the orthogonal channel combinations of the second APs, and adjacent frequency interference is reduced.
In one embodiment, the method further comprises: maintaining the orthogonal channel combination of the first AP unchanged, and indicating the first AP to maintain the operating channel unchanged;
and determining that the second AP is not included based on the monitoring data, determining that the second total number of the neighbor APs is smaller than a first preset threshold value, and determining that the third total number of the second APs in the neighbor APs is smaller than the second preset threshold value.
Fig. 5 is another schematic flow chart of a channel adjustment method provided by the present invention. As shown in fig. 5, the channel adjustment method provided by the present invention includes:
step 510, receive listening data from a first AP.
The monitoring data from the first AP is frame data of neighbor APs monitored by the first AP in a current working channel.
Step 520, determining whether a second AP exists based on the listening data.
Specifically, it is detected whether all the neighboring APs are APs corresponding to the vendor type of the first AP, if there is no second AP (neighboring AP of a vendor type different from the vendor type of the first AP), step 570 is directly performed, otherwise step 530 is further performed.
In step 530, it is determined whether the second total number of neighbor APs reaches a first preset threshold.
Judging whether the second total number of neighbor APs (the sum of the numbers of APs of the same vendor type as the first AP and the second AP in the listening data) reaches the first preset threshold, wherein the neighbor APs are very few, and are considered to not generate serious interference, directly executing step 570, otherwise further executing step 540.
Step 540, determining whether the third total number of second APs in the neighboring APs reaches a second preset threshold.
It may be appreciated that, when it is determined that the second total number of neighboring APs reaches the first preset threshold, a third total number of second APs may be further determined; if the third total number of second APs is very small, step 570 is directly performed, if not, step 550 is further performed, assuming no serious interference is generated.
Step 550 determines whether the working channel list of the second AP is deployed in one or more orthogonal channel combinations.
And counting the working channel list of the second AP in the neighbor APs, and judging whether the working channel list of the second AP is deployed in one or more orthogonal channel combinations. If the working channel list of the second AP is deployed in one or more orthogonal channel combinations, performing step 560; otherwise, step 570 is performed.
Step 560 adjusts the orthogonal channel combination of the first AP to the orthogonal channel combination used by the second AP and instructs the first AP to adjust the operating channel to the target channel in the orthogonal channel combination used by the second AP.
The orthogonal channel combination used by the second AP may be a second orthogonal channel combination or a target channel combination. Specifically, the process of step 560 may refer to step 340 and step 350, which are not described herein for brevity.
Step 570, maintaining the orthogonal channel combination of the first AP unchanged and instructing the first AP to maintain the operating channel unchanged.
