[0030] In the existing wireless AP networking control scheme, only one access controller is set in the same wireless AP networking. When the access controller fails, the related services of the entire wireless AP networking will be affected. The embodiment of the present invention provides a distributed networking control method, in which a controller is set for each wireless AP in the wireless AP networking, and the controllers are used to control the wireless APs in the wireless AP networking to achieve the selection of the optimal channel and roaming switching.

[0031] In some embodiments, the wireless APs in the wireless AP networking are connected to the same Layer 2 network. When the wireless AP is idle, the controller scans the entire wireless AP networking to obtain a list of neighboring wireless access nodes, and then determines the best channel based on the current channel parameters and historical statistical parameters of the neighboring wireless access nodes, or determines the best wireless AP based on the operating parameters of the neighboring networking APs, and roams the site to switch to the best wireless AP.

[0032] Figure 1 The structure diagram of the distributed networking of the embodiment of the present disclosure. The distributed networking includes a first wireless AP1, a second wireless AP2, a third wireless AP3, a fourth wireless AP4, a fifth wireless AP5, a sixth wireless AP6, and a seventh wireless AP7, and these seven wireless APs are connected to the same layer 2 network. In some embodiments, at least one of the seven wireless APs has a built-in control point module (Controller) and a control agent module (Agent). In some embodiments, each wireless AP has a built-in control point module and a control agent module, and the fourth wireless AP4 is associated with the station STA1 (Station).

[0033] Among them, each control point module can only control the wireless AP corresponding to it, but can access the control agent modules of other wireless APs. For example, the fourth control point module Controller4 built into the wireless AP4 can only control the fourth control agent module Agent4, and cannot control other control agent modules. The control agent module records the operating parameters of the wireless access node corresponding to it, such as average channel utilization and bandwidth. When the control point module scans the wireless AP in the wireless AP network, the operating parameters of the corresponding wireless AP can be obtained through the control agent module.

[0034] It should be noted that the average channel utilization refers to the average channel utilization and bandwidth in each time period of a week, for example, the average channel utilization in each hour of a week.

[0035] In a first aspect, an embodiment of the present disclosure provides a distributed networking control method. Figure 2 Flow chart of the distributed networking control method of the embodiment of the present disclosure. This embodiment is described by taking distributed Wi-Fi networking as an example.

[0036] Reference Figure 2 , the distributed networking control method includes:

[0037] 201, scanning the wireless access point network to obtain a list of neighboring wireless access points.

[0038] A wireless AP in the wireless access node network performs a full channel scan of the wireless access node network to obtain a neighbor wireless access node list, that is, the neighbor wireless access node list only includes wireless access nodes that can be scanned, and wireless access nodes that have not been scanned are not included in the neighbor wireless access node list. In addition, the wireless access node that performs the scan scans the wireless access node, and obtains the basic service set identifier, service set identifier, and received signal strength identifier of each neighbor wireless access result.

[0039] For example, the fourth wireless AP4 in the distributed Wi-Fi network scans the distributed Wi-Fi network, and when the second wireless AP2, the third wireless AP3, the fifth wireless AP5, the sixth wireless AP6, and the seventh wireless AP7 are scanned as neighboring wireless APs, the second wireless AP2, the third wireless AP3, the fifth wireless AP5, the sixth wireless AP6, and the seventh wireless AP7 are added to the neighboring wireless access node list.

[0040] In some embodiments, the wireless access point performing scanning performs full channel scanning when the service is idle to obtain a list of neighboring wireless access nodes. For example, the fourth wireless AP4 performs full channel scanning of the wireless AP network when its service is idle to obtain a list of wireless access nodes.

[0041] In some embodiments, the wireless access node performing scanning performs full channel scanning at fixed time intervals to obtain a list of neighboring wireless access nodes. For example, the wireless access node performing scanning performs full channel scanning for wireless access node networking every four hours. In some embodiments, the wireless access node performing scanning performs full channel scanning for wireless access node networking every four hours from 8:00 to 23:00 every day. In some embodiments, the wireless access node performing scanning performs full channel scanning for wireless access node networking at fixed time intervals when it is idle.

[0042] In some embodiments, the wireless access node performing the scan may also use other strategies to scan the wireless access node network.

[0043] In some embodiments, after the scanning wireless access node scans the wireless access node network and obtains neighboring wireless access nodes, the scanning results of the wireless access nodes are filtered, and then the filtered neighboring wireless access nodes are added to the neighboring wireless access node list.

[0044] In some embodiments, filtering is performed by using a service set identifier (SSID) and the signal strength of a neighboring wireless access point. Specifically:

[0045] Determine whether the service set identifier of the neighbor wireless access node is the same as the service set identifier of the wireless access node performing the scan, and if not, filter out the neighbor wireless access node;

[0046] It is determined whether the received signal strength of the neighboring wireless access node is greater than a preset signal strength value; if not, the neighboring wireless access node is filtered out.

[0047] During the filtering process, since the neighboring wireless access nodes with long distance and weak signals have little or almost no effect on the current wireless access node, the neighboring wireless access nodes with long distance and weak signals are added to the list, that is, the neighboring wireless access nodes with the same service set identifier and the received signal strength greater than the preset signal strength value are added to the wireless access node list, and the wireless access nodes that do not meet the conditions are filtered out.

[0048] For example, the preset signal strength value is set to -70dbm. The neighboring wireless access points with the same service set identifier and a signal strength greater than -70dbm are

[0049] 202: Determine the best wireless access point or the best channel according to the performance parameters of the neighbor wireless access points in the neighbor wireless access point list.

[0050] It should be noted that the performance parameters of the wireless access node include historical statistical parameters and current channel parameters. Among them, the historical channel utilization rate includes the average channel utilization rate and channel bandwidth in the historical time period. The current channel parameters include but are not limited to the current working channel, the current working bandwidth and the current channel utilization rate.

[0051] In some embodiments, the step of determining the best wireless access node according to the performance parameters of the neighbor wireless access nodes in the neighbor wireless access node list includes:

[0052] The performance parameters of the neighbor wireless access nodes in the neighbor wireless access node list are obtained. The estimated utilization of the channel is calculated according to the historical statistical parameters of the neighbor wireless access nodes and the current channel parameters; and the channel with the smallest estimated utilization of the channel is determined as the best channel.

[0053] For example, the control point module Controller4 of the fourth wireless AP can query the historical statistical parameters and current channel parameters of the second wireless AP2 through the second control agent module Agent2.

[0054] In some embodiments, after the control point module Controller4 of the fourth wireless AP obtains the performance parameters of the neighboring wireless access node, the historical statistical parameters and current channel parameters of the neighboring wireless access node are calculated to calculate the estimated utilization of the channel. In some embodiments, the estimated channel utilization of each channel is calculated based on the current working channel and current working bandwidth of the neighboring wireless access node, combined with the historical average channel utilization of the corresponding neighboring wireless access node. It should be noted that when calculating the estimated channel utilization, the situation where the bandwidth occupies multiple channels is combined.

[0055] A channel with the smallest estimated channel utilization is found from the calculation results, and the channel with the smallest estimated channel utilization is determined as the best channel, and then the best channel is used.

[0056] In some embodiments, a site associated with a wireless access node is used to scan a wireless access node network to obtain a neighbor wireless access node list. The method of obtaining a neighbor wireless access node list by using a site is the same as the method of obtaining a neighbor wireless access node list by directly scanning a wireless access node, which will not be repeated here.

[0057] It should be noted that the station associated with the wireless access point communicates with the wireless access point through the 802.11k protocol standard.

[0058] Figure 3 The present invention is a flowchart of implementing fast roaming sites according to neighboring wireless access nodes according to an embodiment of the present invention.

[0059] In some embodiments, when a wireless access node obtains a neighboring wireless access node, if the wireless access node is associated with a site, roaming switching of the site can also be implemented. Specifically:

[0060] 301. Determine whether the site needs to roam according to a preset rule.

[0061] The preset rule includes at least one of the number of sites associated with the wireless access node and the minimum signal strength of the site roaming.

[0062] In some embodiments, whether the site STA1 needs to roam is determined based on the number of sites associated with the fourth wireless AP4. For example, when the number of sites associated with the fourth wireless AP4 exceeds a preset number, it is determined that the site needs to roam. In some embodiments, whether the site STA1 needs to roam is determined based on the minimum signal strength of the site. For example, when the signal strength provided by the fourth wireless AP4 is less than the minimum signal strength of the site STA1, it is determined that the site needs to roam. In some embodiments, whether the site STA1 needs to roam is determined based on the number of sites associated with the fourth wireless AP4 and the minimum signal strength of the site. For example, when the number of sites associated with the fourth wireless AP4 exceeds a preset number, and the signal strength provided by the fourth wireless AP4 is less than the minimum signal strength of the site STA1, it is determined that the site needs to roam.

[0063] 302 : When the site needs to roam, obtain the operation parameters of the wireless access node that performs scanning of the wireless access node networking and the neighbor wireless access node in the neighbor wireless access node list.

[0064] The operation parameter of the wireless access node includes at least one of the load, channel utilization and signal strength of the wireless access node.

[0065] 303 , comparing the operating parameters of the wireless access node that performs scanning of the wireless access node network and the neighbor wireless access nodes in the neighbor wireless access node list, and determining the wireless access node with the best operating parameters as the best wireless access node.

[0066] In some embodiments, the load of the wireless access node that performs scanning of the wireless access node network and the load of the wireless access node in the wireless access node group are compared, and the wireless access node with the smallest load is selected as the best wireless access node. In some embodiments, the channel utilization of the wireless access node that performs scanning of the wireless access node network and the load of the wireless access node in the wireless access node group are compared, and the wireless access node with the smallest channel utilization is selected as the best wireless access node. In some embodiments, the signal strength of the wireless access node that performs scanning of the wireless access node network and the load of the wireless access node in the wireless access node group are compared, and the wireless access node with the largest signal strength is selected as the best wireless access node. In some embodiments, the load, channel utilization and signal strength of the wireless access node that performs scanning of the wireless access node network and the load of the wireless access node in the wireless access node group are compared, and the wireless access node with the best load, channel utilization and signal strength is selected as the best wireless access node. For example, compare the signal strength, the number of associated sites is less than a preset threshold, and the channel utilization is less than a set threshold (such as 60%) of the neighboring wireless access nodes.

[0067] In some embodiments, after obtaining the best wireless access node, the station roams to the best wireless access node. For example, the fourth wireless AP4 roams the station STA1 to the best wireless access node through the 802.11k protocol.

[0068] Figure 4 The following is a flow chart of obtaining a list of neighbor wireless access nodes in the distributed networking control method of an embodiment of the present disclosure. The steps of obtaining a list of neighbor wireless access nodes include:

[0069] 401. Determine whether the service of the wireless access node is idle.

[0070] The wireless access nodes in the wireless access node network scan the wireless access node network when the service is idle. Therefore, it is necessary to determine whether the service of the wireless access node is idle.

[0071] 402, the wireless access node scans all channels of the wireless access node network.

[0072] The wireless access node scans the wireless access node network in all channels to obtain neighboring wireless access nodes, wherein the scanning result includes the basic service set identifier (BSSID), service set identifier (SSID) and received signal strength identifier (RSSI) of the neighboring wireless access node.

[0073] 403: Filter the scanned neighbor wireless access points.

[0074] It is determined whether the service set identifier of the neighbor wireless access node is the same as the service set identifier of the wireless access node performing the scan. If not, it means that the channel of the neighbor wireless access node is far away from the current channel and has little impact on the current signal, so the neighbor wireless access node is filtered out.

[0075] In some embodiments, it is determined whether the received signal strength of the neighboring wireless access node is less than a preset signal strength value. If so, it indicates that the signal strength of the neighboring wireless access node is weak and has little impact on the current wireless access node, and the neighboring wireless access node is filtered out.

[0076] In some embodiments, it is determined whether the service set identifier of the neighboring wireless access node is the same as the service set identifier of the wireless access node performing the scan, and at the same time, it is determined whether the received signal strength of the neighboring wireless access node is less than a preset signal strength value, and the neighboring wireless access nodes whose service set identifier is different from the wireless access node performing the scan are filtered out, and the neighboring wireless access nodes whose received signal strength is less than a preset value are filtered out.

[0077] 404, adding the filtered neighbor wireless access point to the neighbor wireless access point list.

[0078] The neighboring wireless access nodes whose service set identifiers are the same as the service set identifiers of the wireless access nodes performing the scan and whose received signal strengths are greater than the preset signal strength value are added to the neighboring wireless access node list. For example, the control point module Controller4 of the fourth wireless AP4 adds the filtered neighboring wireless access node AP2 to the neighboring wireless access node list.

[0079] The neighbor wireless access node list obtained in this embodiment can provide relevant parameters for channel optimization and roaming switching.

[0080] Figure 5 The present invention is a flow chart of channel optimization in the distributed networking control method according to an embodiment of the present invention.

[0081] The steps of channel optimization include:

[0082] 501, obtain a list of neighboring wireless access points.

[0083] The neighbor wireless access point list can be obtained through steps 401 to 404, which will not be described in detail here.

[0084] 502, determine whether the current wireless access node is idle.

[0085] The current wireless access point performs signal optimization when the service is idle.

[0086] 503, obtaining wireless access point performance parameters.

[0087] The control point module Controller of the current wireless access node queries the control agent module Agent of the neighboring wireless access node to obtain the performance parameters of the neighboring wireless access node. Among them, the performance parameters include historical statistical parameters and current channel parameters. The historical statistical parameters include but are not limited to the average channel utilization and bandwidth of each hour of each week. The current channel parameters include the current working channel, the current working bandwidth and the current channel utilization.

[0088] 504, calculate and estimate channel utilization.

[0089] The control point module Controller of the current wireless access node calculates the estimated channel utilization of each channel based on the current working channel and current working bandwidth of the neighboring wireless access node and the historical average channel utilization of the corresponding neighboring wireless access node. It should be noted that when calculating the estimated channel utilization, the situation where the bandwidth occupies multiple channels is taken into consideration.

[0090] 505, select the best channel.

[0091] The current wireless access node finds the channel with the smallest estimated channel utilization rate from the calculation results, and determines the channel with the smallest estimated channel utilization rate as the best channel.

[0092] Figure 6 The flowchart of the fast roaming site in the distributed networking control method of the embodiment of the present disclosure. The steps of fast roaming site include:

[0093] 601, obtain a list of neighboring wireless access points.

[0094] The neighbor wireless access point list can be obtained through steps 401 to 404, which will not be described in detail here.

[0095] 602, associate the site with the current wireless access point.

[0096] The station STA1 is associated with the current wireless access point, such as associating the station STA1 with the fourth wireless AP4.

[0097] 603 , determine whether the station STA1 needs to roam.

[0098] The control point module Controller of the current wireless access node determines whether the station STA1 needs to roam according to a preset rule.

[0099] The preset rule includes at least one of the number of associated sites and the minimum signal strength of the site roaming.

[0100] In this embodiment, whether the station STA1 needs to roam is determined based on the number of stations associated with the fourth wireless AP4 and the minimum signal strength of the station. For example, when the number of stations associated with the fourth wireless AP4 exceeds a preset number and the signal strength provided by the fourth wireless AP4 is less than the minimum signal strength of the station STA1, it is determined that the station needs to roam.

[0101] 604, obtaining the operation parameters of the wireless access point.

[0102] The operation parameters of the wireless access node include the load of the wireless access node, channel utilization and signal strength.

[0103] When station STA1 needs to roam, the control point module Controller of the current wireless access node queries the neighboring wireless access node to obtain the load and channel utilization of the neighboring wireless access node through the control agent module Agent. Station STA1 measures the signal strength of the neighboring wireless access node through 802.11k.

[0104] 605 , comparing the operating parameters of the current wireless access point and the neighboring wireless access point.

[0105] The signal strengths of the current wireless access node and the neighboring wireless access nodes, the number of their associated stations, and the channel utilization are compared, and the wireless access node with the best operating parameters is determined as the best wireless access node.

[0106] The wireless access node with the best operating parameters is the wireless access node with the strongest signal strength, the least number of associated sites, and the lowest channel utilization. In some embodiments, the wireless access node with the highest score is determined comprehensively based on signal strength, the number of associated sites, and the channel utilization, and is the best wireless access node.

[0107] Determine whether the number of sites associated with the wireless access node is less than a preset maximum value, and determine whether the channel utilization of the wireless access node is less than a set threshold, such as the set threshold is 60%. If so, it means that in the wireless access node networking, there is a neighboring wireless access node that is better than the current wireless access node.

[0108] 606, switching the site to the best wireless access point.

[0109] The current wireless access point enables station STA1 to roam to the best neighboring wireless access point through 802.11k.

[0110] The distributed networking control method provided by the embodiment of the present disclosure obtains a list of neighbor wireless access nodes by scanning the wireless access node network; then determines the best wireless access node or the best channel according to the performance parameters of the neighbor wireless access nodes in the neighbor wireless access node list, thereby realizing the optimization and roaming switching of channels within the wireless access node network group. Even if a wireless access node fails, it will not affect the normal operation of the entire wireless access node network, and reduces the technical requirements and costs of the control point.
