Before describing the embodiments of the present application, a brief description of the system environment in which the present application may be used will be provided. In the WLAN system, the wireless access point AP serves as a management device of the network, manages all terminal devices, and provides access and transmission services to the terminal devices. As shown in fig. 1, the WLAN system includes a processing unit (which may be a microprocessor) connected to a plurality of base bands, such as base band 1, base band 2, base band 3, and base band 4 in fig. 1, where each base band has three transceivers, but may also be a plurality of transceivers, and each transceiver is connected to one antenna to form an antenna array. Wherein each baseband may operate in a frequency band, such as a 2.4GHz frequency band or a 5GHz frequency band. Different combinations of antenna arrays may form different radiation patterns. The connection mode of the processing unit and each baseband can adopt a PCIE (PCI-Express, bus and interface standard) mode.

As shown in fig. 2, a diagram in fig. 2 is a radiation diagram formed by combining four base bands at the same frequency band, if the four base bands all work at 5GHz band, 36, 48, 149 and 157 channels can be used respectively, and if the four base bands all work at 2.4GHz band, 1,6,11 and 13 channels can be used respectively. The b diagram in fig. 2 is a radiation diagram formed by combining three base bands at the same frequency band, and if one of the base bands operates in the 5GHz frequency band and the other base band operates in the 2.4GHz frequency band, 149, 1,6 and 11 channels can be used respectively. The diagram c in fig. 2 shows the radiation pattern of two base bands combined at the same time.

The four base bands may be configured with the same Service Set Identifier (SSID) to form an ESS. It can be understood that one AP may include multiple base bands, and if the four base bands are mentioned above, the AP may operate in a single frequency band, such as a 5GHz frequency band or a 2.4GHz frequency band, and may also operate in a dual frequency band, such as a 5GHz frequency band and a 2.4GHz frequency band, of course, the AP may also operate in other frequency bands besides the two frequency bands, such as a 5.8GHz frequency band, and in practical applications, the AP may be flexibly set to other frequency band values.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a wireless access point according to an embodiment of the present disclosure, where the wireless access point may include: at least one processor 110, such as a CPU, at least one communication interface 120, at least one memory 130, and at least one communication bus 140. Wherein the communication bus 140 is used for realizing direct connection communication of these components. The communication interface 120 of the device in the embodiment of the present application is used for performing signaling or data communication with other node devices. The memory 130 may be a high-speed RAM memory or a non-volatile memory (e.g., at least one disk memory). Memory 130 may optionally be at least one memory device located remotely from the aforementioned processor. The memory 130 stores computer readable instructions that, when executed by the processor 110, cause the wireless access point to perform the method process of fig. 4 described below.

Referring to fig. 4, fig. 4 is a flowchart of an access method provided in an embodiment of the present application, where the method is applied to the above-mentioned wireless access point (hereinafter, referred to as AP for short), the AP operates in at least one frequency band, and each frequency band is configured with a plurality of channels, and the method includes the following steps:

step S110: and determining at least two channels of a target frequency band in the at least one frequency band supported by the terminal equipment to be accessed into the network.

As described above, the AP may operate in at least one frequency band, which may be a 2.4GHz frequency band or a 5GHz frequency band, or may also operate in two frequency bands, such as a 2.4GHz frequency band and a 5GHz frequency band. Wherein, the frequency range of the 2.4GHz band is 2.4GHz-2.4835GHz, and the frequency range of the 5GHz band is 5.150GHz-5.350GHz and 5.725GHz-5.850 GHz.

It should be understood that, as technology evolves, at least one frequency band in the embodiments of the present application may also include other frequency bands, and the embodiments of the present application are not limited to the above listed frequency bands.

It should be understood that, when the at least one frequency band is one frequency band, the target frequency band is the one frequency band. When the at least one frequency band is a plurality of frequency bands, the target frequency band may be any one of the plurality of frequency bands, or the target frequency band may be a specific one of the plurality of frequency bands, for example, the target frequency band may be one frequency band determined from the plurality of frequency bands according to a manner described below, or the target frequency band may also be one frequency band determined from the plurality of frequency bands according to other manners, which is not limited in this embodiment of the application.

The channel refers to a data signal transmission channel using a wireless signal as a transmission medium, and the channel corresponds to a specific frequency, for example, the frequency corresponding to the channel 1 is 2.412GHz of a 2.4GHz band, that is, the channel can be understood as a specific operating frequency of a radio frequency. That is, each frequency band may include multiple frequencies, that is, each frequency band is configured with multiple channels, and each channel may access multiple terminal devices.

When the terminal device wants to associate with the AP, it may obtain the wireless networks existing around the terminal device by an active scanning or passive scanning manner, where the active scanning process is as follows: the terminal device may send broadcast Probe information (i.e., a Probe Request message) to the AP through a channel supported by the terminal device, that is, when the terminal device wants to connect to a wireless network, the terminal device may actively send the broadcast Probe information to the AP through the channel supported by the terminal device, and detect the wireless network stored around the terminal device through the broadcast Probe information.

The passive scanning process is as follows: the passive scanning means that the terminal device may not actively send broadcast probe information to the AP, but the AP sends a Beacon frame (i.e., Beacon frame), where the Beacon frame sent by the AP includes information such as a wireless network identifier and a supported frequency band of the AP, and the AP may send the Beacon frame by broadcasting periodically, for example, a default period of the Beacon frame sent by the AP is 100ms, that is, the AP may send the Beacon frame by broadcasting every 100ms, and the terminal device may listen to the Beacon frame on each channel supported by the terminal device, so as to learn about the wireless network existing around.

The following describes the process of connecting to the wireless network by taking active scanning of the terminal as an example. Since the terminal device generally supports at least one frequency band, for example, if the terminal device supports a 2.4GHz frequency band, the frequency band in which the AP operates includes the 2.4GHz frequency band, the terminal device may send broadcast probe information to the AP through a specific channel in the 2.4GHz frequency band supported by the terminal device, when the terminal device supports only one channel of one frequency band, the terminal device only sends broadcast probe information to the AP through the one channel, and after receiving the broadcast probe information, the AP operating in the frequency band may directly guide the terminal device to access the channel.

In the embodiment of the present application, an example in which a terminal device supports at least two channels is described. The terminal device may send the target broadcast detection information to the AP through at least two channels of the target frequency band supported by the terminal device, and if the terminal device supports at least two channels of the target frequency band of 2.4GHz, the terminal device sends the target broadcast detection information to the AP through the at least two channels, and after receiving the target broadcast detection information sent by the terminal device through the two channels, the AP may know that the terminal device supports the at least two channels. For example, if the terminal device supports three channels 1,6, and 11 in the 2.4GHz band, when the terminal device wants to access the wireless network, the terminal device may send broadcast probe information to the outside through the three channels, and then the AP operating in the 2.4GHz band may determine that the terminal device supports three channels 1,6, and 11 in the 2.4GHz band after receiving the target broadcast probe information.

That is, the AP determines that the terminal device supports at least two channels when receiving target broadcast probe information transmitted by the terminal device through the at least two channels of the target frequency band.

Step S120: and determining a target channel accessible by the terminal equipment according to the load conditions of the at least two channels.

After the channels supported by the terminal device are determined through the above process, in order to ensure load balance among the channels, the load condition of each channel is also required to be obtained, and the target channel accessible to the terminal device is determined according to the load condition of each channel.

As an implementation manner, in order to determine the load condition of each channel more clearly, the number of devices accessed to each channel may be obtained first, then the load condition of each channel is determined according to the number of devices accessed to each channel, then the channel with the minimum load is determined, and then the channel with the minimum load is taken as the target channel accessible to the terminal device.

That is to say, the load conditions of the channels may be characterized by the number of devices accessed by the channels, for example, if the terminal device supports three channels 1,6, and 11 in the 2.4GHz band, the load conditions of the three channels 1,6, and 11 may be obtained respectively, and the number of devices currently accessed by the channels represents the load conditions thereof. For example, the number of devices currently accessed by the channel 1 is 321, the number of devices currently accessed by the channel 6 is 223, and the number of devices currently accessed by the channel 11 is 35, so that the load of the channel 11 is the smallest, and therefore, in order to balance the loads of the respective channels, it may be determined that the target channel accessible by the terminal device is the channel 11.

Of course, the load condition of each channel is not only determined by the number of devices accessed by the channel, but also determined by combining the signal strength of the channel and the number of devices accessed by the channel, for example, if the number of devices accessed by the channel 6 is large, but the signal strength of the device is strong, the load may also be small, and of course, the specific determination mode may be set according to actual requirements, and the embodiment of the present application is not limited thereto.

Alternatively, in this embodiment of the present application, one of the channels with a smaller load may be determined as a target channel according to a load condition of the channel, for example, the load condition may be classified into some grades, for example, the load grade is classified from 1 to 10, where the grades 1 to 10 respectively indicate that the load is higher and higher (the load is higher and lower may be calculated by a ratio of load traffic to a total capacity of the channels), the target channel may be one of the channels with a lowest load grade, or one of the channels with a lower load grade than a preset threshold grade, for example, the threshold grade is grade 5, there are a plurality of channels with a load grade lower than the threshold grade, and the target channel may be any one of the channels with a load grade lower than the threshold grade, which is not limited in this embodiment of the present application.

Step S130: and sending indication information to the terminal equipment.

After determining a target channel to be accessed by the terminal device, the AP may send indication information to the terminal device through the target channel, where the indication information may indicate that the terminal device is accessed to the target channel of the target frequency band, and thus, the terminal device may perform a subsequent access process after receiving the indication information.

In addition, in the above embodiment, the specific channel supported by the terminal device is directly identified, rather than only identifying the frequency band supported by the terminal device, and if only the frequency band supported by the terminal device is identified, the AP may direct the terminal device to access any channel in the frequency band, but if the terminal device does not support the channel, the problem that the terminal device cannot access the channel is caused.

As an example, in order to more accurately determine a channel supported by a terminal device, a duration for identifying the channel supported by the terminal device is further configured on an AP, and a specifically set value of the duration needs to ensure that the channel supported by the terminal device can be completely identified without affecting access experience of the terminal device, that is, the AP may further determine whether broadcast probe information sent by the terminal device through at least two channels is received within a preset time period, and if so, determine that the terminal device supports at least two channels.

In addition, after the AP receives the target broadcast probe information sent by the terminal device through the at least two channels, the AP may also send first response information for the target broadcast probe information to the terminal device through the at least two channels, where the first response information is used to indicate that the terminal device may access the at least two channels.

For example, after receiving the target broadcast probe information sent by the terminal device through the channels 1 and 6 of the 2.4GHz band, the AP may listen to the target broadcast probe information sent by the terminal device on the channels 1 and 6, and then the AP sends first response information to the terminal device through the channels 1 and 6, where the first response information is used to indicate that the terminal device may access the channels 1 and 6, and the terminal device may request to access the channels 1 and 6 after receiving the first response information.

When the terminal equipment requests to access the channel 1 and the channel 6, the terminal equipment can respectively send request access information to the AP through the channel 1 and the channel 6, if the AP determines that a target channel which can be accessed by the terminal equipment is the channel 6 according to the load conditions of the channel 1 and the channel 6, the AP can send indication information to the terminal equipment through the channel 6, and does not respond to the request access information sent by the terminal equipment through the channel 1, so that the terminal equipment can be indicated to access the channel 6.

In addition, if the AP does not respond after receiving the target broadcast probe information sent by the terminal device, the terminal device may give up access, so the AP may also send the first response information for the target broadcast probe information to the terminal device through at least two channels according to the preset time interval. It can be understood that the AP is provided with a preset time interval, where the preset time interval is the number of times of replying the broadcast probe information of the terminal device, for example, a first response message is sent to the terminal device after receiving how many broadcast probe information sent by the terminal device, and the purpose is to retain the association intention of the terminal device, effectively prevent the terminal device from giving up access, and avoid the problem of association failure of the terminal device.

As an example, after receiving target broadcast probe information sent by a terminal device through at least two channels, an AP sends first response information to the terminal device through the at least two channels, and the terminal device knows that the at least two channels can be accessed after receiving the first response information, and then the terminal device sends request access information to the AP through the at least two channels, where the request access information is used for requesting to access a certain channel. If the AP determines the target channel to which the terminal device wants to access according to the load conditions of the at least two channels, the AP receives the access request information sent by the terminal device for the target channel, where the access request information indicates that the terminal device requests to access the target channel, and the AP may send second response information to the terminal device according to the access request information, where the second response information includes the indication information.

It can be understood that the process of sending the request access information to the AP by the terminal device may be understood as an authentication process, the authentication process is link authentication, the terminal device and the AP are connected through a wireless link, during the process of establishing the link, the terminal device needs to be authenticated through the wireless link, and only after the authentication is passed, the wireless association between the terminal device and the AP can be performed.

The link authentication comprises development system authentication and shared key authentication, Open system authentication is called Open authentication for short, and authentication is not performed, as long as terminal equipment sends request access information, the AP allows the authentication to be successful, and the link authentication is an unsafe authentication mode, so shared key authentication is generally adopted. The procedure of shared key authentication is as follows: before authentication, the same secret key is configured on terminal equipment and an AP, otherwise, the authentication cannot be successful, when the authentication is started, the terminal equipment sends an authentication request (namely request access information) to the AP, then the AP generates a challenge phrase after receiving the authentication request, then the challenge phrase is sent to the terminal equipment, if the challenge phrase is A, the terminal equipment encrypts the challenge phrase A by using the secret key of the terminal equipment, sends the encrypted challenge phrase A to the AP, if the encrypted challenge phrase is B, finally, the AP receives the encrypted information B of the terminal equipment and decrypts by using the secret key of the AP, if the secret key configuration on the terminal equipment and the AP is constant, the decrypted result is A, if the result is inconsistent, the authentication fails, and if the result is consistent, the authentication succeeds.

After the authentication is successful, that is, the AP sends second response information to the terminal device, where the second response information includes the above-mentioned indication information, that is, indicates the terminal device to access the target channel. After receiving the second response message, the terminal device enters an association stage, and in the association stage, the terminal device may send association request message to the AP through the target channel, where the association request message includes various parameters of the terminal device itself and various parameters selected according to service configuration, such as rate supported by the terminal device, channel, QoS capability, and selected access authentication and encryption algorithm.

The AP can be divided into a fat AP and a thin AP according to the working mode, the fat AP can independently realize wireless services, and the thin AP needs to be combined with a wireless controller to realize the wireless services. Therefore, if the fat AP receives the association request information of the terminal device, the fat AP may directly determine whether the terminal device is to perform Access authentication subsequently And respond to the terminal device, if the thin AP receives the association request information of the terminal device, the thin AP is responsible for encapsulating the association request information by a Control And Provisioning protocol (CAPWAP) of the Wireless Access point And then sending the encapsulated association request information to the Wireless controller, And the Wireless controller performs the determination processing, And the thin AP is also responsible for decapsulating the processing result of the Wireless controller by the CAPWAP And then sending the encapsulated association request information to the terminal device. After the association is completed, it indicates that a wireless link has been established between the terminal device and the AP, if no access authentication is configured, the terminal device may access the wireless network after obtaining the IP address, and if the access authentication is configured, the terminal device may perform network access only after completing the stages of access authentication, key agreement, and the like.

It should be noted that the terminal device may send the request access information through the channel supported by the terminal device, and for the request access information sent by other channels except the target channel, the AP does not respond to the request access information sent by the terminal device through other channels, so as to enable the terminal device to actively continue to send the request access information to other channels, for example, actively send the request access information through the target channel, thereby guiding the terminal device to access the target channel, so as to implement load balancing between channels.

If the AP sends the indication information to the terminal device to indicate that the terminal device accesses the target channel, the terminal channel does not access the target channel later, that is, the terminal device does not send the association request information through the target channel within a certain period of time, it indicates that the terminal device does not want to associate with the target channel that the AP wants to associate with, and in order to ensure that the terminal device can successfully connect with the AP, the terminal device can be further controlled to access another channel. That is, if the AP does not detect that the terminal device accesses the target channel, it is determined whether access request information of the terminal device through another channel other than the target channel among at least two channels supported by the AP is received, and if so, the AP controls the terminal device to access the other channel.

It will be appreciated that, in order not to affect the access behaviour of the terminal device, to ensure that the terminal device is in any case able to successfully associate with the AP, but not always influencing the access behavior of the terminal equipment, resulting in the problems of too long association time or no association of the terminal equipment, if the request access information sent by the terminal device through another channel is received at this time when the guidance of the terminal device to access the target channel is unsuccessful, indicating that the terminal device wants to access another channel, the terminal device is controlled to access other channels, the specific method is also consistent with the method for indicating the terminal device to access the target channel, i.e. also sending an indication to the terminal device based on the requested access information, instructing the terminal device to access further information, the terminal device may send association request information to the AP after receiving the indication information, and the AP may directly allow the terminal device to access other channels of the AP.

In addition, most APs and terminal devices may support two frequency bands, that is, a 5GHz frequency band and a 2.4GHz frequency band, but the terminal devices all work in the 2.4GHz frequency band, so that when the terminal devices access a wireless network, the terminal devices access the 2.4GHz frequency band of the AP by default, which may cause an overload of the 2.4GHz frequency band, thereby causing poor network utilization, and the 5GHz frequency band is idle at this time, which also causes a problem of resource waste.

As an example, the AP may operate in at least two frequency bands, and the terminal device may also support two frequency bands, so that before determining at least two channels of a target frequency band supported by the terminal device, a network frequency band supported by the terminal device may be determined, and when the network frequency band supported by the terminal device includes at least two frequency bands, a target frequency band accessible by the terminal device is determined according to a load request of the at least two frequency bands, where the target frequency band is one of the at least two frequency bands.

Taking an example that the at least two frequency bands include a first frequency band and a second frequency band, if the network frequency bands that can be supported by the terminal device include the first frequency band and the second frequency band, the terminal device is a dual-frequency band terminal device, and if the terminal device only supports the first frequency band or the second frequency band, the terminal device is a single-frequency band terminal device. The first frequency band may be 2.4GHz, the second frequency band may be 5GHz, or vice versa, the first frequency band may be 5GHz, and the second frequency band may be 2.4GHz, it should be understood that specific values of the first frequency band and the second frequency band are not limited to the above two manners, and when the AP further operates in other frequency bands, such as 5.8GHz, the AP may also be flexibly set to other frequency band values.

The implementation manner of determining the target frequency band accessible to the terminal device according to the load conditions of the at least two frequency bands may be: obtaining the number of devices accessed under each frequency band, for example, counting the number of devices accessed by each channel under the 2.4GHz frequency band and counting the number of devices accessed by each channel under the 5GHz frequency band, the frequency band with the smaller number of access devices can be used as the target frequency band accessed by the terminal device, for example, if the number of devices accessed by the 5GHz frequency band is greater than the number of devices accessed by the 2.4GHz frequency band, the target frequency band accessible by the terminal device is determined to be the 2.4GHz frequency band, and if the number of devices accessed by the 5GHz frequency band is less than or equal to the number of devices accessed by the 2.4GHz frequency band, the target frequency band accessible by the terminal device is determined to be the 5GHz frequency band.

Because the terminal equipment generally supports the 2.4GHz frequency band, and in a wireless network, the 5GHz frequency band has higher access capacity, generally speaking, the 2.4GHz frequency band can only have 3 non-overlapping communication channels at most, and the 5GHz frequency band can provide more non-overlapping communication channels, therefore, when the terminal equipment is determined to support two frequency bands, the terminal equipment can be directly guided to access the 5GHz frequency band, so as to relieve the problem of congestion of the 2.4GHz frequency band.

In the implementation process, the target frequency band accessed by the terminal device is determined according to the load conditions of the two frequency bands, so that the problem of network congestion of one frequency band can be effectively alleviated, the utilization rate of the network is improved, the resource balance between the two frequency bands can be ensured, the problem that resources of one frequency band are congested and resources of the other frequency band are wasted is avoided, and the utilization rate of network resources and the experience effect of a user are improved.

As an example, in order to accurately obtain a network frequency band supported by a terminal device, in the process of determining a target frequency band supported by the terminal device, it may be determined whether first broadcast detection information sent only by the terminal device through a first frequency band is received, and if so, the network frequency band supported by the terminal device is determined to be the first frequency band; judging whether second broadcast detection information sent by the terminal equipment only through a second frequency band is received, and if so, determining that the network frequency band supported by the terminal equipment is the second frequency band; and judging whether first broadcast detection information sent by the terminal equipment through a first frequency band and second broadcast detection information sent by the terminal equipment through a second frequency band are received, and if so, determining that the network frequency bands supported by the terminal equipment comprise the first frequency band and the second frequency band.

In order to more accurately determine the network frequency band supported by the terminal device, the terminal device may not respond to the broadcast detection information when only receiving the broadcast detection information sent by the terminal device through the first frequency band or the second frequency band within a preset time period, and the terminal device may continuously send the broadcast detection information at different frequency bands when the terminal device supports multiple frequency bands, so that the terminal device may not respond to the broadcast detection information sent by the terminal within the preset time period to determine the frequency band where the broadcast detection information sent by the terminal device is located, and further determine the network frequency band supported by the terminal device.

For example, when the first frequency band is 2.4GHz and the second frequency band is 5GHz, since the terminal devices basically support the 2.4GHz band, in order to alleviate network congestion of the 2.4GHz band, when receiving broadcast Probe information sent by the terminal device for the 2.4GHz band, the terminal device may not respond, and when receiving broadcast Probe information sent by the terminal device for the 5GHz band, directly respond (the Response message is a Probe Response message) to guide the terminal device to directly access the specified channel in the 5GHz band.

As an example, the implementation manner of determining the target frequency band accessible to the terminal device according to the load conditions of the at least two frequency bands may be: and when the load ratio of the first frequency band to the second frequency band is smaller than the preset ratio, determining that the target frequency band accessible to the terminal equipment is the first frequency band.

The load ratio of the first frequency band to the second frequency band can be obtained by the following formula:

Wherein, the preset ratio can be set according to actual requirements.

In addition, the current terminal device has one 2.4GHz radio frequency and two 5GHz radio frequencies at the same time, that is, the terminal device supports different channels in two frequency bands, the two 5GHz radio frequencies operate in different channels (such as 36 channels and 149 channels), when the terminal device only supports 149 channels but not 36 channels, if the channel supported by the terminal device is not identified in detail, if only the terminal device supports the 5GHz frequency band, the terminal device is guided to the 36 channels, and at this time, the terminal device does not support, and the problem of association failure occurs. Therefore, in the embodiment of the application, not only the frequency band supported by the terminal device is simply identified, but also the frequency band supported by the terminal device can be identified first, then the channel supported by the terminal device is identified, or the channel supported by the terminal device is directly identified, and then the frequency band supported by the terminal device is identified, so that the terminal device can be better compatible with the terminal devices of different manufacturers, and the terminal device can be ensured to be successfully accessed to the wireless network under the condition of considering the load balance among the channels.

As an example, in order to reduce resource occupation of an AP, when a terminal device wants to associate with the AP, the AP identifies a frequency band and a channel supported by the terminal device by the above method, and then the AP generates a record entry for each terminal device, where the record entry records the frequency band and the channel supported by the terminal device and a status parameter, and if the terminal device does not receive any message from the terminal device after disconnecting from the AP, the record entry corresponding to the terminal device is deleted by an aging mechanism after a period of time, so as to ensure that excessive storage resources of the AP are not occupied.

And when the terminal equipment is disconnected after being successfully associated with the AP, the terminal equipment is associated before the record item corresponding to the terminal equipment in the AP is not aged, the relevant information of the terminal equipment in the record item can be directly used for processing, the support capability of the terminal equipment does not need to be identified again, the association speed of the terminal equipment can be further improved, and the user experience is increased to a certain extent.

The method provided by the present application is described in detail below with a specific example.

If the AP operates in two frequency bands, an SSID list maintenance unit is configured in the AP, and when the AP configures the WLAN, the SSID list maintenance unit divides the channel configured with the SSID to operate into 2.4GHz and 54GHz circle sets, as shown in fig. 5. The circle records the working frequency band of the AP and the corresponding channel.

The 2.4G circle set is a channel list of the AP working at the 2.4GHz frequency band, the 5G circle set is a channel list of the AP working at the 5GHz frequency band, and the intersection of the 2.4G circle set and the 5G circle set is that the AP not only works at the 2.4GHz channel but also works at the 5GHz channel.

In order to flexibly adapt to various scenes and meet different requirements, the AP can also provide a parameter configuration processing unit, when the AP works in a thin AP mode, the AP needs to be managed by a wireless controller and supports the wireless controller to issue and configure parameters, when the AP works in a fat AP mode and does not need the management of the wireless controller, the AP can be configured through a configuration command or a configuration page of the fat AP, and when the AP is not configured, a default value is provided.

The parameter configuration processing unit is used for identifying parameters such as duration, preset time interval of reply information, frequent guidance and preset ratio.

The AP is further provided with a state machine and a terminal device maintenance unit, where the state machine is mapped to each terminal device to be associated, that is, when each terminal device is associated, the state machine needs to go once to complete the entire association action. The terminal equipment maintenance unit is mainly used for recording and maintaining the support information and the state information of the identified terminal equipment.

The state machine is provided with the following states, and the working process of the state machine is shown in fig. 6:

1. recognizing the state: in this state, the broadcast probe information sent by the terminal device is mainly analyzed to obtain a channel list supported by the terminal device. The method comprises two sub-states of recognition completion and recognition overtime, wherein the recognition completion refers to the completion of channel support recognition on the terminal equipment, and the recognition overtime refers to the situation that a channel list supported by the terminal equipment is not recognized within the configured recognition duration.

2. A guiding state: when the identification of the terminal equipment is finished or overtime in the identification state, the AP receives the access request information sent by the terminal equipment after obtaining the channel list supported by the terminal equipment, then the AP guides the terminal equipment to actively send the access request information to other information by not responding to the access request information, and if the access request information sent by the terminal equipment through a target channel is received, the AP sends indication information to the terminal equipment to indicate the terminal equipment to access the target channel.

3. Guiding an ultrasonic state: when the terminal equipment enters the state, the access request information sent by the terminal equipment through other channels is directly responded at the stage, and the access behavior of the terminal equipment is not influenced, which indicates that the terminal equipment does not have access to the target channel which the AP wants to access.

4. Unknown state: when the state machine does not operate according to the preset flow or is abnormal, the state machine enters the state, the state directly responds to any information about association sent by the terminal equipment, and the successful access of the terminal equipment is ensured in any way.

In addition, in the pilot state, it is necessary to obtain a pilot target, i.e., a pilot target channel, and in consideration of the diversity of APs, there are two cases:

1. when a wireless network to be associated with a terminal device works on a plurality of channels with the same frequency band and different frequency bands, load calculation between the frequency bands is not needed in the situation, and only the channel with the least load needs to be found. For example, currently, a wireless network operates at two 5GHz radio frequencies, a first 5GHz radio frequency operates at a 149 channel, and a second 5GHz radio frequency operates at a 165 channel, where if the number of devices accessed on the 149 channel is 20 and the number of devices accessed on the 165 channel is 19, it is determined that a target channel to be accessed by a terminal device is 165 channel, and if the number of devices accessed on the 149 channel is the same as that of the devices accessed on the 165 channel, it is determined that the terminal device can access any one of the two channels.

2. When a wireless network to which a terminal device is to be associated works on different channels of a plurality of different frequency bands, a channel set needs to be obtained through the algorithm and the configured parameters, the set is a channel set for guiding the terminal device to access, when the channel to which the terminal device is to access meets any one sub-item in the set, the terminal device meets the access condition, and the parameter setting is as shown in the following table 1:

substituting the above formula:

s ═ 100% can be obtained ((N2/N2-N1/N1)/(N2/N2)).

And when the S is larger than or equal to S%, selecting a 2.4GHz frequency band as a frequency band accessed by the terminal equipment, and then selecting a target channel to be accessed by the terminal equipment under the 2.4GHz frequency band according to the load condition between the channels.

And when the S is less than S%, selecting a 5GHz frequency band as a frequency band accessed by the terminal equipment, and then selecting a target channel to be accessed by the terminal equipment under the 5GHz frequency band according to the load condition between the channels.

For example, if two 2.4GHz radios and two 5GHz radios exist on the AP device at present, the wireless network operates in the two frequency bands (providing 2.4GHz and 5GHz services), the sum of the devices accessed on the two 2.4GHz radios is 10, and the sum of the devices accessed on the two 5GHz radios is 10, and then since 5GHz transmission data is better than 2.4GHz, the preset ratio may be set to 50%, that is, ideally, the 2.4GHz load and the 5GHz load are 1: 2.

Substituting the above formula to obtain (100-50) × (10/2) >100 × (10/2), if the formula is not satisfied, the terminal device should be guided to access the 5GHz band.
