Referring to figure 3., Fig. 3 is a kind of structural schematic diagram of wireless access point provided by the embodiments of the present application, described wireless Access point may include: at least one processor 110, such as CPU, at least one communication interface 120, at least one processor 130 and at least one communication bus 140.Wherein, communication bus 140 is for realizing the direct connection communication of these components.Wherein, The communication interface 120 of equipment is used to carry out the communication of signaling or data with other node devices in the embodiment of the present application.Memory 130 can be high speed RAM memory, be also possible to non-labile memory (non-volatile memory), for example, at least One magnetic disk storage.Memory 130 optionally can also be that at least one is located remotely from the storage device of aforementioned processor.It deposits Computer-readable instruction fetch is stored in reservoir 130, when the computer-readable instruction fetch is executed by the processor 110, Wireless access point executes method process shown in following Fig. 4.

Referring to figure 4., Fig. 4 is a kind of flow chart of cut-in method provided by the embodiments of the present application, and this method is applied to upper The wireless access point (abbreviation AP below) stated, AP work are configured with multiple channels at least one frequency range, each frequency range, should Method includes the following steps:

Step S110: the target frequency bands at least one described frequency range of the terminal device support of network to be accessed are determined At least two channels.

As described above, AP can work at least one frequency range, at least one frequency range can for 2.4GHz frequency range or 5GHz frequency range or AP can also work in two frequency ranges, such as 2.4GHz frequency range and 5GHz frequency range.Wherein, 2.4GHz frequency range Frequency range is 2.4GHz-2.4835GHz, and the frequency range of 5GHz frequency range is 5.150GHz-5.350GHz and 5.725GHz- 5.850GHz。

It should be understood that at least one frequency range in the embodiment of the present application can also include other frequencies with the evolution of technology Section, the embodiment of the present application are not limited to the above-mentioned frequency range enumerated.

It should be understood that the target frequency bands are a frequency range when at least one frequency range is a frequency range.This at least When one frequency range is multiple frequency ranges, which can be any one frequency range in multiple frequency range, alternatively, target frequency Section can be specific one frequency range in multiple frequency range, for example, target frequency bands can be the mode according to described in hereafter It is also possible to be determined from multiple frequency ranges according to other modes from the frequency range or target frequency bands determined in multiple frequency range One again and again, the embodiment of the present application is not limited to this.

Wherein, channel refers to the data-signal Transfer pipe using wireless signal as transmission media, channel and specific frequency Rate is at corresponding relationship, and such as the 2.412GHz that the corresponding frequency of channel 1 is 2.4GHz frequency range, i.e. it is specific to can be understood as radio frequency for channel The frequency of work.That is, each frequency range may include having multiple frequencies, i.e., each frequency range is configured with multiple channels, each Channel can access multiple terminal devices.

Terminal device can obtain its week by way of active scan or drive sweep when wanting to be associated with AP Enclose existing wireless network, the process of active scan is as follows: terminal device can be sent by the channel that it is supported to AP It broadcasts detection information (i.e. Probe Request message), that is to say, that terminal device can lead to when wanting connection wireless network It crosses the channel oneself supported and broadcasts detection information to AP active transmission, by broadcast detection information come around detecting terminal equipment The wireless network of storage.

The process of drive sweep is as follows: drive sweep refers to that terminal device actively can not send broadcast detection letter to AP Breath, but sent by AP beacon frame (i.e. Beacon frame), it include the wireless network identification of the AP in the beacon frame that AP is sent With the information such as band support, AP can regular outside broadcast transmission beacon frame, such as the default cycles of beacon frame that AP is sent are The every 100ms of 100ms, i.e. AP all can beacon frame of broadcast transmission, terminal device be exactly by its support each channel on Beacon frame is listened to, existing wireless network around is known with this.

Illustrate that it connects the process of wireless network by taking terminal active scan as an example below.Generally all due to terminal device At least one frequency range can be supported, for example, the frequency range of above-mentioned AP work includes 2.4GHz if terminal device supports 2.4GHz frequency range Frequency range, so, terminal device can send broadcast detection letter to AP by the specific channel in 2.4GHz frequency range that it is supported Breath, when terminal device only supports a channel of a frequency range, then terminal device can only be sent out by this channel to AP Send broadcast detection information, then work after the AP of the frequency range receives the broadcast detection information, can directly guiding terminal equipment connect Enter the channel.

And in the embodiment of the present application, it is illustrated so that terminal device supports at least two channels as an example.Terminal device can be with Target broadcast detection information is sent to AP by least two channels of its target frequency bands supported, as terminal device supports mesh When mark frequency range is at least two channel in 2.4GHz frequency range, then terminal device sends target to AP by this at least two channel Detection information is broadcasted, AP is known after receiving the target broadcast detection information that terminal device is sent by the two channels Dawn terminal device supports this at least two channel.For example, if terminal device supports 1,6,11 these three channels of 2.4GHz frequency range, Then terminal device can be sent out broadcast detection information by these three channels respectively, then when wanting access wireless network Work 2.4GHz frequency range AP after receiving the target broadcast detection information, it may be determined that the terminal device support 2.4GHz frequency 1,6,11 these three channels of section.

That is, AP is visited in the target broadcast for receiving at least two channels transmission of the terminal device by target frequency bands In the case where measurement information, determine that terminal device supports at least two channels.

Step S120: determine that the accessible target of the terminal device is believed according to the loading condition of at least two channel Road.

After determining channel that terminal device is supported by the above process, in order to ensure the load between each channel Equilibrium also needs the loading condition for obtaining each channel, determines what terminal device can access according to the loading condition of each channel Destination channel.

As an implementation, it in order to more clearly determine the loading condition of each channel, can first obtain The quantity for the equipment that each channel is accessed, the quantity of the equipment then accessed according to each channel determine each channel Loading condition, then determine and load the smallest channel, the target that then can access the smallest channel is loaded as terminal device is believed Road.

That is, the loading condition of channel can be characterized by the quantity for the equipment that channel is accessed, for example, if eventually End equipment supports 1,6,11 these three channels of 2.4GHz frequency range, then can obtain the load feelings of 1,6,11 these three channels respectively Condition, the quantity for the equipment that channel is currently accessed characterize its loading condition.For example, the quantity for the equipment that channel 1 is currently accessed It is 321, the quantity for the equipment that channel 6 is currently accessed is 223, and the quantity for the equipment that channel 11 is currently accessed is 35, thus As it can be seen that the load of channel 11 is minimum, so then can determine the accessible target of terminal device to balance the load of each channel Channel is channel 11.

Certainly, the quantity of the equipment that the loading condition of each channel is accessed not only by above-mentioned channel determines, The loading condition of channel can be determined with the quantity of the signal strength of comprehensive channel and its equipment accessed, for example, if The quantity for the equipment that channel 6 is accessed is larger, but its signal strength is stronger, then its load may be also smaller, certainly, specific true Determining mode can set according to actual needs, and the embodiment of the present application is not limited to this.

Alternatively, in the embodiment of the present application, can also according to the loading condition of channel, will load it is lesser one of them Channel is determined as destination channel, for example, loading condition can delimit as some grades, for example, the grade of load from 1 to 10 divides, Grade 1 to 10 respectively indicates load, and higher and higher (height of load can be by the total capacity ratio of payload traffic amount and channel To be calculated), which can be a minimum channel of the grade of load in multiple channels, be also possible to be responsible for grade Lower than one of channel of preset threshold grade, for example, threshold levels are class 5, the grade of load is lower than the letter of threshold levels Road have it is multiple, then the destination channel can be the grade of load lower than threshold levels multiple channels in any one channel, The embodiment of the present application is not limited to this.

S130: Xiang Suoshu terminal device of step sends instruction information.

AP can send instruction letter to terminal device by destination channel after determining the destination channel that terminal device need to access Breath, the instruction information can indicate the destination channel of terminal device access target frequency bands, in this way, terminal device is receiving instruction letter Breath, can carry out subsequent access procedure.

In addition, be the specific channel that Direct Recognition goes out that terminal device is supported in the above-described embodiment, rather than only Identify the frequency range that terminal device is supported, if only identifying the frequency range that terminal device is supported, the bootable terminal device of AP Any channel under the frequency range is accessed, if but the terminal device does not support that will lead to terminal device when the channel can not access The problem of, so, it is the channel for specifically identifying terminal device and being supported, then according between channel in the embodiment of the present application Loading condition determine its accessible destination channel, so as to also may make terminal in the case where equalization channel loads Equipment has access to success.

As an example, for the channel that more accurate determination terminal device is supported, identification is also configured on AP The duration for the channel that terminal device is supported, the value of the duration specifically set need to guarantee do not influencing terminal device access experience While the channel that terminal device is supported can also be identified completely, i.e. AP can also judge whether to receive within a preset period of time Pass through the broadcast detection information that at least two channels are sent to terminal device, if so, determining that terminal device supports at least two Channel.

In addition, AP is also after the target broadcast detection information that AP receives that terminal device is sent by least two channels The first echo message for being directed to target broadcast detection information can be sent to terminal device by least two channels, this is first time Answering information to be used to indicate terminal device can access at least two channels.

For example, AP is in the target broadcast detection for receiving channel 1 and channel 6 transmission of the terminal device by 2.4GHz frequency range After information, i.e. AP can listen to the target broadcast detection information of terminal device transmission on channel 1 and channel 6, and then AP distinguishes The first echo message is sent to terminal device by channel 1 and channel 6, which can connect to instruction terminal equipment Enter channel 1 and channel 6, then terminal device can request access channel 1 and channel 6 after receiving the first echo message.

When premises equipment requests access channel 1 and channel 6, terminal device can be sent by channel 1 and channel 6 to AP respectively Access information is requested, if AP is determining the accessible destination channel of terminal device for letter according to the loading condition of channel 1 and channel 6 When road 6, then instruction information can be sent to terminal device by channel 6, then not respond terminal device and pass through the request that channel 1 is sent Access information can so indicate that terminal device accesses channel 6.

In addition, if AP, if not responding, may be led after the target broadcast detection information for receiving terminal device transmission Terminal device is caused to abandon accessing, so, it can also be sent by least two channels to terminal device according to prefixed time interval For the first echo message of target broadcast detection information.It is to be appreciated that prefixed time interval is provided in AP, when this is default Between between be divided into the interval times for replying the broadcast detection information of terminal device, such as in the broadcast for receiving how many a terminal devices transmissions First echo message is sent to terminal device after detection information, its purpose is to keep the association intention of terminal device here, Terminal device can be effectively prevent to abandon accessing, avoid the problem that terminal device association failure.

As an example, AP receive terminal device pass through at least two channels send target broadcast detection information Afterwards, the first echo message can be sent to terminal device by least two channel, terminal device receives the first echo message After know that this at least two channel can be accessed, then terminal device can by this at least two channel to AP send request access letter Breath, the request access information access some channel for requesting.If AP is determined according to the loading condition of at least two channels at this time Want the destination channel of terminal device access, then receive terminal device again and be directed to the request access information that destination channel is sent, The request access information indicates that premises equipment requests access destination channel, then AP can be according to request access information, to terminal device The second echo message is sent, which includes above-mentioned instruction information.

It is to be appreciated that terminal device can be understood as verification process to the process that AP sends request access information, authenticate Process is link authentication, is to be attached between terminal device and AP by Radio Link, in the process for establishing this link In, the certification for needing to require terminal device by Radio Link, only by just can be carried out between terminal device and AP after certification Wireless association.

Link authentication includes development system certification and shared key authentication, and open system authentication abbreviation Open certification is called It does not authenticate, as long as being to have terminal device to send request access information, AP can allow it to authenticate successfully, be a kind of unsafe Authentication mode, so generally using shared key authentication.The process of shared key authentication is as follows: before certification, in terminal device With identical key is equipped on AP, otherwise cannot authenticate success, start certification when, from terminal device to AP send one recognize Card request (i.e. request access information), then AP can generate a challenge phrase after receiving certification request, then this is challenged Phrase is sent to terminal device, it is assumed that this challenge phrase is A, then terminal device can with oneself key will challenge phrase A into Row encryption, is sent to AP after encryption, it is assumed that has become B after encryption, finally, AP receives information B after the encryption of terminal device, has used The key of oneself is decrypted, as long as the cipher key configuration on terminal device and AP is always, the result decrypted will be A, As a result inconsistent, then as a result unanimously authentification failure then authenticates success.

After the authentication has been successful, i.e. AP sends the second echo message to terminal device, which includes above-mentioned Indicate that information, i.e. instruction terminal equipment access destination channel.Terminal device then enters association after receiving the second echo message In the stage, in association phase, terminal device can send association request information to AP by destination channel, in the association request information Various parameters including terminal device itself and the various parameters according to service configuration selection, the speed supported such as terminal device Rate, channel, the ability of QoS and the access authentication of selection and Encryption Algorithm etc..

Since AP can be divided into fat AP and two kinds of thin AP according to operating mode, fat AP can be implemented separately wireless traffic, and thin AP It needs to be implemented in combination with wireless traffic with wireless controller.So if fat AP receives the association request information of terminal device, then Whether fat AP can directly judge that terminal device is subsequent will carry out access authentication and respond terminal device, receive end if it is thin AP The association request information of end equipment, then thin AP will be responsible for carrying out association request information into control and the configuration protocol of wireless access point Wireless controlled is sent to after (Control And Provisioning of Wireless Access Points, CAPWAP) encapsulation Device processed carries out judgement processing by wireless controller, and thin AP will also be responsible for encapsulating the processing result solution CAPWAP of wireless controller After be then forwarded to terminal device.After the completion of association, show to have had built up Radio Link between terminal device and AP, if Access authentication is not configured, terminal device can be carried out having accessed for wireless network after getting IP address, if configuration Access authentication, then terminal device also needs to complete the stages such as access authentication, key agreement just to can be carried out network access.

It should be noted that terminal device can send request access information by channel that it is supported, for removing mesh The request access information that other channels outside channel are sent is marked, then AP does not respond the request that terminal device is sent by other channels Access information, the purpose is to make terminal device actively continue such as actively to send request access by destination channel to other channels Information, so that guiding terminal equipment accesses destination channel, to realize the load balancing between channel.

If AP is sending instruction information to terminal device, after accessing destination channel with instruction terminal equipment, terminal channel is slow Do not access destination channel late, i.e. terminal device does not send association request information by destination channel within a certain period of time, then table Show that terminal device is not desired to associated AP and wants its associated destination channel, in order to ensure terminal device can with AP successful connection, then Other channels can be accessed with controlling terminal equipment.That is, if AP be not detected terminal device access destination channel when, Determine whether to receive other channels at least two channels that terminal device is supported by it in addition to destination channel Access information is requested, if so, controlling terminal equipment accesses other channels.

It is to be appreciated that in order to not influence the access behavior of terminal device, it is ensured that terminal device anyway can be with AP Successful association, rather than always affect the access behavior of terminal device, causes terminal device correlation time too long or can not be associated Problem can then be believed when guiding terminal equipment access destination channel is unsuccessful if receiving terminal device at this time and passing through other The request access information that road is sent indicates that terminal device is wanted to access other channels, then controlling terminal equipment accesses other channels, tool Body way is also consistent with the way of above-mentioned instruction terminal equipment access destination channel, i.e., and according to request access information to terminal Equipment sends instruction information, and instruction terminal equipment accesses other information, then terminal device, can be to AP after receiving the instruction information Association request information is sent, then AP can directly allow terminal device to access other channels of the AP.

In addition, AP and terminal device may all support two frequency ranges, i.e. 5GHz frequency range and 2.4GHz frequency range mostly at present, but It is that terminal device is all accustomed to sex work in 2.4GHz frequency range, so terminal device can all default access when accessing wireless network The 2.4GHz frequency range of AP, this may will lead to the overload of 2.4GHz frequency range, it is poor in turn result in network utilization, and at this time The problem of 5GHz frequency range is idle, also leads to the wasting of resources, so, in order to avoid these problems, it is also necessary to identify terminal device The frequency range supported, the frequency range then specified according to the loading condition guiding terminal equipment access between frequency range.

As an example, AP may work at least two frequency ranges, and terminal device may also support two frequency ranges, institute Can also first determine what terminal device was supported before determining at least two channels of target frequency bands of terminal device support Network frequency range, when the network frequency range that terminal device is supported includes at least two frequency range, then according to the load of at least two frequency ranges It requests to determine that the target frequency bands that terminal device is accessible, the target frequency bands are one of frequency range at least two frequency ranges.

By taking at least two frequency ranges include the first frequency range and the second frequency range as an example, if the supported network frequency range packet of terminal device The first frequency range and the second frequency range are included, then this terminal device is dual band terminals equipment, if terminal device only supports the first frequency range Or second frequency range, then this terminal device is one-segment terminal device.Wherein, the first frequency range can be 2.4GHz, the second frequency range It can be 5GHz, otherwise the first frequency range can also be set as to 5GHz, the second frequency range is set as 2.4GHz, it should be appreciated that first The specific value of frequency range and the second frequency range is not limited to above two mode, when AP also operates at other frequency ranges, such as 5.8GHz, It then can also flexibly be set as other frequency range values.

Wherein, the implementation of the accessible target frequency bands of terminal device is determined according to the loading condition of at least two frequency ranges It can be with are as follows: the quantity for obtaining the equipment accessed under each frequency range, such as setting of being accessed of each channel under statistics 2.4GHz frequency range Each channel is accessed under standby quantity, and statistics 5GHz frequency range the quantity of equipment, in the negligible amounts of access device Frequency range can be used as the target frequency bands of terminal device access, for example, if the quantity of the equipment of 5GHz frequency range access is greater than 2.4GHz frequency When the quantity for the equipment that section is accessed, it is determined that the accessible target frequency bands of terminal device are 2.4GHz frequency range, if 5GHz frequency range When the quantity of the equipment of access is less than or equal to the quantity for the equipment that 2.4GHz frequency range is accessed, it is determined that terminal device can access Target frequency bands be 5GHz frequency range.

Since terminal device generally all supports 2.4GHz frequency range, and in the wireless network, 5GHz frequency range possesses higher connect Enter amount, it is however generally that, 2.4GHz frequency range can only at most have 3 nonoverlapping communication channels, and 5GHz frequency range can provide more not The communication channel of overlapping, so, when determining that terminal device supports two frequency ranges, directly guiding terminal equipment 5GHz frequency can be accessed Section, to alleviate the crowded problem of 2.4GHz frequency range.

During above-mentioned realization, the target frequency that terminal device is accessed is determined according to the loading condition of two frequency ranges Section, then can be effectively relieved the crowded problem of one of frequency band network, improve the utilization rate of network, then also can guarantee two frequencies Resources balance between section avoids that one of frequency range is crowded the problem of another resource of frequency range wastes, improves network The utilization rate of resource and the experience effect of user.

As an example, in order to accurately obtain the network frequency range that terminal device is supported, terminal device support is being determined Target frequency bands during, can first judge whether to receive terminal device and only pass through the first broadcast of the first frequency range transmission and visit Measurement information, if so, determining that the network frequency range that terminal device is supported is the first frequency range；Judge whether that receiving terminal device only leads to The second broadcast detection information of the second frequency range transmission is crossed, if so, determining that the network frequency range that terminal device is supported is the second frequency range； Judge whether to receive what terminal device was sent by the first broadcast detection information of the first frequency range transmission and by the second frequency range Second broadcast detection information, if so, determining that the network frequency range that terminal device is supported includes the first frequency range and the second frequency range.

In order to more accurately determine out the network frequency range that terminal device is supported, if then can only connect within a preset period of time When receiving the broadcast detection information that terminal device is sent by the first frequency range or the second frequency range, which is not carried out It responds, if terminal device supports multiband, terminal device constantly can send broadcast detection information in different frequency range, therefore can Not respond the broadcast detection information of terminal transmission within a preset period of time, to determine the broadcast detection information of terminal device transmission The frequency range at place, and then determine the network frequency range that terminal device is supported.

For example, the first frequency range is 2.4GHz, when the second frequency range is 5GHz, since terminal device is substantially supported 2.4GHz frequency range, therefore in order to alleviate the network congestion of 2.4GHz frequency range, terminal device can received for 2.4GHz frequency range When the broadcast detection information of transmission, without responding, and when receiving the broadcast detection information that terminal is sent for 5GHz frequency range, (back message is Probe Response message) is directly responded, is directly accessed in 5GHz frequency range with guiding terminal equipment Designated channel.

As an example, the accessible target frequency bands of terminal device are determined according to the loading condition of at least two frequency ranges Implementation can be with are as follows: when the duty ratio value of the first frequency range and the second frequency range is greater than or equal to default ratio, determines that terminal is set Standby accessible target frequency bands are the second frequency range, when the duty ratio value of the first frequency range and the second frequency range is less than default ratio, then Determine that the accessible target frequency bands of terminal device are the first frequency range.

Wherein, the duty ratio value of the first frequency range and the second frequency range can be calculated by following formula and be obtained:

Wherein, default ratio can be set according to actual needs.

In addition, present terminal equipment exists simultaneously a 2.4GHz radio frequency and two 5GHz radio frequencies, i.e. terminal device is supported Different channels in two frequency ranges, the two 5GHz radio frequency operations work as terminal in different channels (such as 36 channels and 149 channels) When equipment only supports 149 channels without supporting 36 channel, if not refining the channel for identifying that terminal device is supported, if only knowing Not Chu terminal device support 5GHz frequency range, and by the terminal device toward guiding on 36 channels, and at this moment terminal device is not It supports, it may appear that the problem of association fails.So being not only to identify what terminal device was supported merely in the embodiment of the present application Frequency range, but can first identify its frequency range supported, then identify that the channel of its support or Direct Recognition go out its support Channel, and then identify its frequency range supported, it can preferably be compatible with the terminal device of different vendor in this way, but also taking into account In the case where load balancing between channel, it can also ensure that terminal device can be successfully accessed wireless network.

As an example, in order to which the resource occupation for reducing AP is known when terminal device is intended to associated AP by the above method Not Chu the frequency range supported of terminal device and channel, then AP can generate an entry, the entry for each terminal device The frequency range and channel and state parameter that terminal device is supported are had recorded, if not receiving again after terminal device is disconnected with AP Any message of terminal device is then over time deleted the corresponding entry of the terminal device by aging mechanism, into And guarantee to be not take up the excessive storage resource of AP.

And it is disconnected after AP on terminal device successful association, then the corresponding entry of the terminal device in AP There is no the terminal device before aging to be associated again, then the relevant information that can directly continue to use terminal device in the entry carries out Processing, without identifying again to the tenability of terminal device, and then can promote the associated speed of terminal device, centainly User experience is increased in degree.

Method provided herein is described in detail with a specific embodiment below.

If AP works in two frequency ranges, a ssid list maintenance unit is configured in AP, ssid list maintenance is single Member will be divided into the circle collection of 2.4GHz and 54GHz according to configuration when AP configures WLAN with the channel that SSID works, such as Shown in Fig. 5.Enclose the frequency range and corresponding channel that centralized recording AP works.

Wherein, 2.4G circle integrates the channel list as AP work in 2.4GHz frequency range, and 5G circle, which integrates, to work as AP in 5GHz frequency range Channel list, it is that AP had not only worked and works again in 5GHz channel in 2.4GHz channel that the intersection of 2.4G and 5G, which goes out,.

In order to be flexibly adapted to various scenes it is different with meeting for it is different the needs of, then parameter configuration can also be provided in AP Processing unit needs wireless controller to be managed, wireless controller is supported to carry out parameter when AP work is under thin ap mode Issue configuration, when AP work is in fat ap mode, when without wireless controller management, at this moment can be ordered by the configuration of fat AP itself It enables or the configuration page is configured, when being not configured, provide default value.

Parameter configuration processing unit be used for by identification duration, return information prefixed time interval, guidance often and The parameters such as default ratio.

It is additionally provided with state machine and maintaining terminal equipment unit on AP, state machine, which is mapped to each and is intended to associated terminal, to be set It is standby, i.e., when each terminal device is associated with, need the state machine to complete entire relevant action.Maintaining terminal equipment unit Mainly record and safeguard the support information and status information of the terminal device recognized.

Wherein, state machine is provided with following state, and the course of work is as shown in Figure 6:

1. identification state: the broadcast detection information that Main Analysis terminal device is sent under the state, to obtain terminal device The channel list supported.It includes that overtime two sub- states are completed and identified in identification, and identification is completed to have referred to that paired terminal is set Standby channel supports identification, and identification time-out refers in the identification duration of configuration, the letter that also unidentified complete terminal device is supported Road list.

2. boot state: after identification state, which identifies terminal device, to be completed or identify time-out, when acquisition terminal device branch After the channel list held and then the state, the request access information that AP receiving terminal apparatus is sent under the state, then using not Responding it requests access information to carry out guiding terminal equipment actively to other information transmission request access information, is such as receiving terminal After the request access information that equipment is sent by destination channel, instruction information is sent to terminal device, is connect with instruction terminal equipment Enter destination channel.

3. guiding ultrasonic state: when entering the state, illustrating that terminal device does not access the target letter that AP wants its access Road then directly responds the request access information that terminal device is sent by other channels at this stage, does not influence terminal device Access behavior.

4. unknown state: when state machine is not operated according to default process, or occurring that the shape can be entered when exception State, the state directly respond terminal device transmission it is any about associated information, ensure anyway terminal device access at Function.

In addition, need to obtain guiding target in boot state, that is, the destination channel guided, in view of existing for AP Diversity is divided into two kinds of situations:

1. the situation is not required to when terminal device is intended to associated wireless network work on multiple similar frequency bands different channels The load between frequency range is wanted to calculate, it is only necessary to find out the least channel of load.For example, wireless network work at present is at two On 5GHz radio frequency, first 5GHz radio frequency operation in 149 channels, second 5GHz radio frequency operation in 165 channels, at this moment if The quantity of the equipment accessed on 149 channels is that the quantity of the equipment accessed on 20,165 channels is 19, then it is determined that terminal device The destination channel that need to be accessed is that 165 channels can be true if the quantity of equipment accessed on 149 channels and 165 channels is identical Determine any one channel that terminal device can access in the two channels.

2. needing to pass through when terminal device is intended to associated wireless network work on the different channels of multiple and different frequency ranges The algorithm above and the parameter of configuration show that a channel set, the collection are combined into the channel set of guiding terminal equipment access, when When the channel that terminal device to be accessed meets any one subitem in set, which meets access conditions, parameter Setting is as shown in table 1 below:

Bring above-mentioned formula into:S=((N2/n2-N1/n1)/(N2/n2)) * can be obtained 100%.

When S is greater than or equal to s%, the frequency range for selecting 2.4GHz frequency range to access as terminal device, then according to channel Between loading condition, the destination channel that need to access of terminal device is selected under 2.4GHz frequency range.

When S is less than s%, the frequency range for selecting 5GHz frequency range to access as terminal device, then according to negative between channel Situation is carried, the destination channel for selecting terminal device that need to access under 5GHz frequency range.

For example, if at present in AP equipment there are two 2.4GHz radio frequencies and two 5GHz radio frequencies, wireless network work simultaneously The summation for making the equipment accessed on the two frequency ranges (providing 2.4GHz and 5GHz service), two 2.4GHz radio frequencies is 10, The summation of the equipment accessed on two 5GHz radio frequencies is 10, at this moment since 5GHz transmission data are better than 2.4GHz, then settable Default ratio is 50%, i.e., ideally 2.4GHz load: 5GHz load=1:2.

It brings above-mentioned formula into, obtains (100-50) * (10/2) > 100* (10/2), the equation is invalid, then answers guiding terminal Equipment accesses 5GHz frequency range.
