It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
Next, examples of the present application will be described in detail.
An embodiment of the present application provides a channel configuration method, where the method is applied to a management node that manages an AP in a WLAN, where the management node may be an AC or a server (e.g., a cloud server, etc.), and as shown in fig. 1, the method may include the following steps:
and S11, acquiring all configurable channels and all neighbor radio frequency units corresponding to each radio frequency unit on each AP in the WLAN.
And S12, counting the number of the radio frequency units corresponding to each acquired configurable channel, and sequencing all the acquired configurable channels according to the sequence of the counted number from small to large.
S13, counting, for each sorted configurable channel, the total number of all configurable channels corresponding to each radio frequency unit of the configurable channel, and sorting all radio frequency units corresponding to each sorted configurable channel according to the order from the smallest total number to the largest total number.
S14, for each configurable channel after sorting, performing the following operations:
aiming at each radio frequency unit which is sequenced and corresponds to the configurable channel, judging whether the radio frequency unit is configured with a formal working channel;
when the judgment result is yes and the configured formal working channel is not the configurable channel, removing the radio frequency unit from all the radio frequency units corresponding to the configurable channel;
if not, further judging whether the same radio frequency unit exists in all the neighboring radio frequency units corresponding to the radio frequency unit and all other radio frequency units configured with the configurable channel or whether the configurable channel exists in formal working channels configured with all the neighboring radio frequency units corresponding to the radio frequency unit;
if the judgment result is negative, the configurable channel is configured as a formal working channel of the radio frequency unit;
if the judgment result is yes, taking the next radio frequency unit as the radio frequency unit, and executing the step of judging whether the radio frequency unit corresponding to the configurable channel is configured with a formal working channel.
Specifically, in step S11, for each AP in the WLAN, in the process of associating and managing the AC of the AP, a temporary operating channel of each radio frequency unit on the AP sent by the AC may be acquired, and each radio frequency unit on the AP operates on the temporary operating channel to detect its own neighboring radio frequency unit. Here, for any rf unit of the AP, its neighboring rf units may be other rf units on the same AP, and may also be rf units on other APs.
When each subsequent AP collects all the neighboring radio frequency units corresponding to its respective radio frequency unit, all the configurable channels corresponding to its respective radio frequency unit may be reported to the management node in a form of a list, and the management node acquires all the neighboring radio frequency units corresponding to each radio frequency unit on each AP.
In step S11, when the management node acquires all configurable channels corresponding to each rf unit on each AP, if all configurable channels corresponding to each AP are stored locally, the management node may directly acquire locally; if not, all configurable channels corresponding to each AP may be obtained from the AC side that manages the APs, or may be obtained from each AP side, for example, the management node obtains all configurable channels and all neighboring radio frequency units corresponding to the respective radio frequency unit that each AP reports at one time.
Regardless of the acquisition mode, all configurable channels corresponding to each rf unit on each AP may also be presented in a list.
It should be noted that, for each radio frequency unit of any AP, the configurable channels corresponding to the radio frequency units may be different under the influence of the respective supported frequency band (e.g., 2.4GHz frequency band or 5GHz frequency band), the supported wireless protocol, the bandwidth, and other factors.
In addition, as for the step S11, the present application does not limit the acquiring order in which the management node acquires all configurable channels and all neighboring radio units corresponding to each radio unit on each AP in the WLAN.
Specifically, in step S12, since the channel numbers of the channels corresponding to different frequency bands are different, it is not necessary to distinguish the channels corresponding to different frequency bands for all the acquired configurable channels, and subsequent configuration can be performed uniformly.
It should be noted that, in step S14, after the management node removes the radio frequency unit from all the radio frequency units corresponding to the configurable channel, if the radio frequency unit is not the last radio frequency unit after being sequenced, the management node continues to determine the next radio frequency unit, that is, starts to execute the step of determining whether the radio frequency unit has configured the formal working channel; if the radio frequency unit is the last radio frequency unit after sequencing, the management node continues to perform the above operation on the next configurable channel.
In the step S14, for the management node, when determining whether the same radio frequency unit exists in all the neighboring radio frequency units corresponding to the radio frequency unit and all the other radio frequency units to which the configurable channel has been configured, the management node may traverse all the neighboring radio frequency units corresponding to the radio frequency unit, compare one by one whether the neighboring radio frequency unit is a radio frequency unit in all the other radio frequency units to which the configurable channel has been configured, and determine that the same radio frequency unit exists in all the neighboring radio frequency units corresponding to the radio frequency unit and all the other radio frequency units to which the configurable channel has been configured once the comparison result is yes, and end the traversal.
Of course, the management node may also traverse all other radio frequency units to which the configurable channel has been configured, compare one by one whether the other radio frequency units are radio frequency units in all neighboring radio frequency units corresponding to the radio frequency unit, and once the comparison result is yes, determine that the same radio frequency unit exists in all neighboring radio frequency units corresponding to the radio frequency unit and all other radio frequency units to which the configurable channel has been configured, and end the traversal.
When judging whether the configurable channel exists in the formal working channels configured by all the neighboring radio frequency units corresponding to the radio frequency unit, the management node may traverse all the neighboring radio frequency units corresponding to the radio frequency unit, query whether the formal working channels configured by the neighboring radio frequency units are the configurable channel, judge whether the configurable channel exists in the formal working channels configured by all the neighboring radio frequency units corresponding to the radio frequency unit once the query result is yes, and end the traversal. In addition, in step S14, when it is determined that the same radio frequency unit exists in all neighboring radio frequency units corresponding to the radio frequency unit and all other radio frequency units to which the configurable channel has been configured, or when it is determined that the configurable channel exists in formal working channels to which all neighboring radio frequency units corresponding to the radio frequency unit have been configured, the management node performs the step of determining whether the formal working channel has been configured by the radio frequency unit corresponding to the configurable channel, with the next radio frequency unit being the radio frequency unit. Here, when the radio frequency unit is not the last radio frequency unit after the sorting, the next radio frequency unit is the next radio frequency unit corresponding to the radio frequency unit in all the radio frequency units after the sorting; and when the radio frequency unit is the last radio frequency unit after sequencing, the next radio frequency unit is the first radio frequency unit after sequencing corresponding to the next configurable channel.
Further, in the embodiment of the present application, the management node further performs the following operations:
after all traversal operations are executed, if radio frequency units which are not configured with formal working channels exist in all sequenced radio frequency units corresponding to all sequenced configurable channels, then for each radio frequency unit which is not configured with formal working channels, the formal working channels configured by the neighbor radio frequency units corresponding to the radio frequency unit are eliminated from all configurable channels corresponding to the radio frequency unit;
if the number of the excluded configurable channels is not 0, selecting the channel which is ranked most front in the ranked configurable channels from the removed configurable channels, and configuring the selected channel as a formal working channel of the radio frequency unit;
if the number of the excluded configurable channels is 0, configuring a formal working channel configured by a neighbor radio frequency unit farthest from the radio frequency unit in all neighbor radio frequency units corresponding to the radio frequency unit as a formal working channel of the radio frequency unit.
It should be noted that, in order to maximize reasonable utilization of channel resources, in the embodiment of the present application, after configuring a formal operating channel for each radio frequency unit in the WLAN, the management node may periodically optimize the formal operating channel of the radio frequency units, and a specific optimization process is the same as the above channel configuration process, and is not described in detail herein.
The channel configuration method is described in detail below with reference to specific embodiments.
Assuming that the management node is an AC, assuming that a WLAN includes APs 1-5, the APs report all configurable channels and all neighboring radio units corresponding to their respective radio units to the AC.
For example, radio unit 1 of AP1, radio unit 2 of AP2, radio unit 3 of AP3, radio unit 4 of AP4, and radio unit 5 of AP5 may correspond to the following configurable channels:
the radio frequency unit 1: a channel A;
the radio frequency unit 2: channel A, channel B;
the radio frequency unit 3: channel A, channel B, channel C;
the radio frequency unit 4: channel C, channel D;
the radio frequency unit 5: channel B, channel D.
Wherein, the channel A, the channel B, the channel C and the channel D are different channel numbers.
For the channel a, the channel B, the channel C, and the channel D, the AC firstly counts the number of the radio frequency units corresponding to the channel a, the channel B, the channel C, and the channel D, and the specific statistical result is as follows:
and a channel A: the number of the corresponding radio frequency units is 3;
and a channel B: the number of the corresponding radio frequency units is 3;
and a channel C: the number of the corresponding radio frequency units is 2;
and a channel D: the number of the corresponding radio frequency units is 2.
Then, the AC sorts the channel a, the channel B, the channel C, and the channel D in the order from the small to the large counted number, and the specific sorting result is as follows:
channel D, channel C, channel B, channel a.
It should be noted that, for channels with the same number of corresponding radio frequencies, there may be no precedence order.
Then, for the sorted channels, the AC first counts the total number of all configurable channels corresponding to each radio frequency unit of the corresponding channel D, channel C, channel B, and channel a, and the specific statistical result is as follows:
and a channel D: the total number of all configurable channels of the corresponding radio frequency unit 4 and the corresponding radio frequency unit 5 is 2;
and a channel C: the total number of all configurable channels of the corresponding radio frequency unit 3 is 3, and the total number of all configurable channels of the corresponding radio frequency unit 4 is 2;
and a channel B: the total number of all configurable channels of the corresponding radio frequency unit 2 is 2, the total number of all configurable channels of the corresponding radio frequency unit 3 is 3, and the total number of all configurable channels of the corresponding radio frequency unit 5 is 2;
and a channel A: the total number of all configurable channels of the corresponding radio frequency unit 1 is 1, the total number of all configurable channels of the corresponding radio frequency unit 2 is 2, and the total number of all configurable channels of the corresponding radio frequency unit 3 is 3.
Then, the AC sorts all the radio frequency units corresponding to the channel D, the channel C, the channel B, and the channel a in the order from the small to the large counted total number, and the specific sorting result is as follows:
and a channel D: a radio frequency unit 4, a radio frequency unit 5;
and a channel C: a radio frequency unit 4, a radio frequency unit 3;
and a channel B: a radio frequency unit 2, a radio frequency unit 5 and a radio frequency unit 3;
and a channel A: radio frequency unit 1, radio frequency unit 2, radio frequency unit 3.
It should be noted that, for the corresponding radio frequency units with the same total number of all configurable channels, there may be no precedence order.
Next, the relevant operations in the above step S14 are performed for the channel D, the channel C, the channel B, the channel a, and the AC, respectively, to implement the configuration of the formal working channel of the corresponding radio frequency unit.
Taking channel D and channel C as an example, for channel D, AC first determines whether radio frequency unit 4 has configured a formal working channel, and since radio frequency unit 4 has not configured a formal working channel, the determination result is no, at this time, AC further determines whether there is the same radio frequency unit in all neighboring radio frequency units corresponding to radio frequency unit 4 and all other radio frequency units to which channel D has been configured, and since channel D has not been configured as a formal working channel of other radio frequency units, the determination result is no, and in this case, AC configures channel D as a formal working channel of radio frequency unit 4.
Then, the AC determines whether the radio frequency unit 5 has configured the formal working channel, and since the radio frequency unit 5 has not configured the formal working channel, the determination result is no, in this case, the AC further determines whether the same radio frequency unit exists in all neighboring radio frequency units corresponding to the radio frequency unit 5 and all other radio frequency units (i.e., the radio frequency unit 4) configured by the channel D, and if the same radio frequency unit exists, the AC continues to determine whether the radio frequency unit 4 of the channel C has configured the formal working channel.
Since the radio frequency unit 4 has configured the formal working channel, the determination result is yes, and the formal working channel (i.e., channel D) configured by the radio frequency unit 4 is not channel C, at this time, the AC removes the radio frequency unit 4 from all the radio frequency units after the sorting corresponding to channel C.
After the removal, the AC continues to determine whether the radio frequency unit 3 has configured the formal working channel, and since the radio frequency unit 3 has not configured the formal working channel, the determination result is no, in this case, the AC further determines whether the same radio frequency unit exists in all neighboring radio frequency units corresponding to the radio frequency unit 3 and all other radio frequency units for which the channel C has been configured, and since the channel C has not been configured as the formal working channel of other radio frequency units, the determination result is no, and in this case, the AC configures the channel C as the formal working channel of the radio frequency unit 3.
For the channel configuration process of the radio frequency unit under other channels, refer to the above related configuration operations, which are not described in detail herein.
According to the technical scheme, the management node sequences the channels according to the number of the radio frequency units corresponding to the channels in the WLAN, and reorders the radio frequency units corresponding to the sequenced channels according to the total number of the configurable channels of each radio frequency unit, so that the actual physical difference or the actual configuration difference of different radio frequency units in the whole WLAN networking can be fully considered, the channel with the minimum collision probability can be preferentially configured, the radio frequency units with the minimum configurable channels and the maximum collision probability can be preferentially configured, and the reasonable utilization rate of channel resources is improved.
