Step 201, obtain currently the first number of the wireless terminal of the radio frequency unit access by first 5GHz and
Pass through the second number of the wireless terminal of the radio frequency unit access of second 5GHz.
In force, AP can be obtained when reaching preset trigger condition and currently pass through the radio frequency list of first 5GHz
The number (i.e. the first number) of the wireless terminal of member access and the wireless terminal accessed by the radio frequency unit of second 5GHz
Number (i.e. the second number).The trigger condition can be configured by technical staff, an embodiment of the present invention provides it is several not
Same trigger condition, specific processing mode can be as follows：
First way receives wirelessly when by the radio frequency unit of first 5GHz or the radio frequency unit of second 5GHz
When the association request message that terminal is sent, the wireless terminal for obtaining that the radio frequency unit currently by first 5GHz accesses is executed
First number and the step of by the second number of the wireless terminal of the radio frequency unit access of second 5GHz.
In force, when accessing wireless terminal to wireless network, it can be sent and be closed to AP by the radio frequency unit of the 5GHz of itself
Join request message.AP then can receive wireless end by the radio frequency unit of first 5GHz or the radio frequency unit of second 5GHz
The association request message sent is held, the first of the currently wireless terminal of the radio frequency unit access by first 5GHz is then obtained
Second number of number and wireless terminal by the radio frequency unit access of second 5GHz.
Optionally, SSID (Service Set Identifier, service set) is carried in association request message, when
The association request that wireless terminal transmission is received by the radio frequency unit of first 5GHz or the radio frequency unit of second 5GHz disappears
When breath, executes and obtain currently the first number of the wireless terminal of the radio frequency unit access by first 5GHz and by the
Second number step of the wireless terminal of the radio frequency unit access of two 5GHz, including：When the radio frequency list by first 5GHz
When the radio frequency unit of member or second 5GHz receive the association request message of wireless terminal transmission, penetrating for first 5GHz is judged
Whether binding has the corresponding wireless services of SSID to the radio frequency unit of frequency unit and second 5GHz.If first 5GHz's penetrates
The radio frequency unit of frequency unit and second 5GHz, which are bound, the corresponding wireless services of SSID, then executes acquisition currently by first
First number of the wireless terminal of the radio frequency unit access of a 5GHz and the nothing of radio frequency unit access by second 5GHz
Second number step of line terminal.
In force, when AP is received wirelessly by the radio frequency unit of first 5GHz or the radio frequency unit of second 5GHz
When the association request message that terminal is sent, the radio frequency of the radio frequency unit and second 5GHz of first 5GHz can be further judged
Whether binding has the corresponding wireless services of SSID to unit.If the radio frequency of the radio frequency unit and second 5GHz of first 5GHz
Unit, which is bound, the corresponding wireless services of SSID, then illustrates that AP can be by the radio frequency unit of first 5GHz and second
The radio frequency unit of 5GHz provides wirelessly access for wireless terminal, and AP can be obtained currently through the radio frequency list of first 5GHz
The first number of wireless terminal that member has accessed and the wireless terminal accessed by the radio frequency unit of second 5GHz
The second number.
If the radio frequency unit binding of first 5GHz has the corresponding wireless services of SSID, the radio frequency unit of second 5GHz
It is unbound to have the corresponding wireless services of SSID, then illustrate that AP is only capable of providing for wireless terminal by the radio frequency unit of first 5GHz
Wirelessly access after AP receives association request message, can be abandoned and be received by the radio frequency unit of second 5GHz
The association request message that wireless terminal is sent, and associated response is sent to wireless terminal by the radio frequency unit of first 5GHz and is disappeared
Breath.
Wireless terminal receives the associate response message that AP is sent by the radio frequency unit of second 5GHz, does not receive AP
The associate response message sent by the radio frequency unit of first 5GHz, can be accessed by the radio frequency unit of first 5GHz of AP
Wireless network.The radio frequency unit of first 5GHz is unbound have the corresponding wireless services of SSID, second 5GHz radio frequency unit
Binding has the case where SSID corresponding wireless services similar therewith, and details are not described herein again.
The second way executes acquisition and currently passes through the radio frequency list of first 5GHz when reaching preset detection cycle
Second number of the first number of the wireless terminal of member access and wireless terminal by the radio frequency unit access of second 5GHz
Purpose step.
In force, preset detection cycle can be stored in AP, which can be set by technical staff
It sets.When reaching preset detection cycle, AP can obtain currently accessed by the radio frequency unit of first 5GHz it is wireless
Second number of the first number of terminal and the wireless terminal accessed by the radio frequency unit of second 5GHz.
The third mode, when the nothing of the radio frequency unit access for the radio frequency unit or second 5GHz for detecting first 5GHz
After the number change of line terminal, the first number for obtaining the currently wireless terminal of the radio frequency unit access by first 5GHz is executed
Mesh and the step of by the second number of the wireless terminal of the radio frequency unit access of second 5GHz.
In force, AP can record the number of the wireless terminal of the radio frequency unit access of first 5GHz and pass through
The number of the wireless terminal of the radio frequency unit access of second 5GHz.By taking the radio frequency unit of first 5GHz as an example, when AP passes through
The radio frequency unit of first 5GHz accesses wireless terminal, alternatively, the radio frequency unit of first 5GHz of AP accessed it is wireless
When terminal is offline, the number of the wireless terminal of the radio frequency unit access of first 5GHz can change.
When AP detects the wireless terminal of the radio frequency unit access of the radio frequency unit or second 5GHz of first 5GHz
When number changes, AP can obtain the first number of the wireless terminal currently accessed by the radio frequency unit of first 5GHz
Second number of mesh and the wireless terminal accessed by the radio frequency unit of second 5GHz.
Step 202, if the first number is more than the second number, and the difference of the first number and the second number is more than preset
Difference threshold, then by the radio frequency unit of second 5GHz by accessing wireless terminal to wireless network.
In force, preset difference threshold is stored in AP, which is configured by technical staff.AP is obtained
To after the first number and the second number, the first number and the second number can be compared.If the first number is equal with the second number,
Then without processing.If the first number is more than the second number, AP can calculate the difference of the first number and the second number.So
Afterwards, AP judges whether the difference is greater than or equal to preset difference threshold, if the difference is greater than or equal to preset difference threshold
Value then illustrates that the number of the wireless terminal of the radio frequency unit access of first 5GHz is excessive, and the radio frequency unit of second 5GHz
The number of the wireless terminal of access is less, and wireless terminal can be accessed wireless network by follow-up AP by the radio frequency unit of second 5GHz
Network.The case where second number is more than the first number is similar therewith, repeats no more.
Optionally, the specific of accessing wireless terminal to wireless network is processed above by the radio frequency unit of second 5GHz
Journey can be divided into following three kinds of modes：
First way, if receiving nothing by the radio frequency unit of first 5GHz and the radio frequency unit of second 5GHz
The association request message that line terminal is sent then sends associated response to wireless terminal by the radio frequency unit of second 5GHz and disappears
Breath, so that wireless terminal accesses wireless network by the radio frequency unit of second 5GHz of AP.
In force, when wireless terminal accesses wireless network by AP, can by the radio frequency unit of the 5GHz of itself to
AP sends association request message, and AP can then receive the association request message.At this point, since the radio frequency unit of first 5GHz connects
The number of the wireless terminal entered is excessive, and the number of the wireless terminal of the radio frequency unit access of second 5GHz is less, so, AP
Associate response message can be sent to wireless terminal by the radio frequency unit of second 5GHz so that wireless terminal pass through AP second
The radio frequency unit of a 5GHz accesses wireless network.
The second way is sent by the radio frequency unit of first 5GHz and carries the beacon Beacon frames that SSID is empty,
So that wireless terminal is detecting that AP carries SSID not and be empty Beacon by what the radio frequency unit of second 5GHz was sent
After frame, wireless network is accessed by the radio frequency unit of second 5GHz.
In force, SSID can be stored in AP, which can be configured by technical staff.When AP is worked normally
When, AP can be respectively by the radio frequency unit transmission Beacon frames of the radio frequency unit and second 5GHz of first 5GHz, should
The SSID is carried in Beacon frames.
When AP judges that the first number is more than the second number, and the difference of the first number and the second number is more than preset difference
After threshold value, the curriculum offering of SSID in the beacon Beacon frames sent by the radio frequency unit of first 5GHz can be sky by AP,
Then it is sent again.That is, AP can be sent by the radio frequency unit of first 5GHz carries the beacon that SSID is empty
Beacon frames, it is empty Beacon frames to be sent by the radio frequency unit of second 5GHz and carry SSID not.
After wireless terminal receives Beacon frames, which can be parsed, obtain Beacon carryings
SSID, so that it is determined that whether AP provides itself required service.Wireless terminal receives radio frequencies of the AP by second 5GHz
After the Beacon frames that unit is sent, the SSID can be got, is somebody's turn to do to judge that AP is provided by the radio frequency unit of second 5GHz
The corresponding services of SSID；And after wireless terminal receives Beacon frames of the AP by the radio frequency unit transmission of first 5GHz, it obtains
It is sky to get the SSID, to judge that the AP does not provide the service by the radio frequency unit of first 5GHz.In this way, wireless terminal
Probe request message can be sent to the radio frequency unit of second 5GHz of AP, without the radio frequency unit of from first 5GHz to AP
Send probe request message.
After AP receives the probe request message, it can be sent and be visited to wireless terminal by the radio frequency unit of second 5GHz
Survey response message.It, can be to the radio frequency list of second 5GHz of AP after wireless terminal receives the probe response message of AP transmissions
Member sends association request message.After AP receives the association request message by the radio frequency unit of second 5GHz, pass through second
The radio frequency unit of a 5GHz sends associate response message to wireless terminal, and wireless terminal can then pass through second 5GHz's of AP
Radio frequency unit accesses wireless network.
The third mode, if receiving nothing by the radio frequency unit of first 5GHz and the radio frequency unit of second 5GHz
The probe request message that line terminal is sent then sends probe response to wireless terminal by the radio frequency unit of second 5GHz and disappears
Breath；When the radio frequency unit by second 5GHz receives the association request message of wireless terminal transmission, AP passes through second
The radio frequency unit of 5GHz sends associate response message to wireless terminal, so that radio frequency of the wireless terminal by second 5GHz of AP
Unit accesses wireless network.
In force, when wireless terminals operational, wireless terminal can send probe request message to AP.AP passes through first
After the radio frequency unit of the radio frequency unit of 5GHz and second 5GHz receive the probe request message, second 5GHz can be passed through
Radio frequency unit send probe response message to wireless terminal, the service that AP can be provided is carried in the probe response message
SSID.After wireless terminal receives the probe response message of AP transmissions, it can be sent to the radio frequency unit of second 5GHz of AP
Association request message.After AP receives the association request message, sent to wireless terminal by the radio frequency unit of second 5GHz
Associate response message.After wireless terminal receives the associate response message of AP transmissions, then it can pass through second 5GHz's of AP
Radio frequency unit accesses wireless network.
Optionally, AP can also pass through the nothing of the radio frequency unit access of the radio frequency unit or second 5GHz of first 5GHz
After the number of line terminal is more than certain proportion, the radio frequency unit of radio frequency unit and second 5GHz to first 5GHz is born
Carry equalization operation.Correspondingly, the processing procedure of step 202 can be as follows：If the first number is more than the second number, obtain pre-
The radio frequency unit of first 5GHz first stored allows the number upper limit of the wireless terminal of access.It determines in the first number and number
The ratio of limit.If ratio is more than preset fractional threshold, it is determined that the difference of the first number and the second number.If difference is big
In preset difference threshold, then by the radio frequency unit of second 5GHz by accessing wireless terminal to wireless network.
In force, the radio frequency unit of first 5GHz can be stored in AP allows the number upper limit of the wireless terminal accessed
(can be described as the first number upper limit) and the number upper limit for allowing the wireless terminal accessed with the radio frequency unit of second 5GHz
(can be described as the second number upper limit).AP gets the wireless terminal currently accessed by the radio frequency unit of first 5GHz
After first number and the second number of the wireless terminal accessed by the radio frequency unit of second 5GHz, it can be determined that
Whether the first number is more than the second number, if the first number is more than the second number, illustrates the radio frequency unit of first 5GHz
It is unbalanced with the number of the wireless terminal of the radio frequency unit access of second 5GHz, and the radio frequency unit access of first 5GHz
The number of wireless terminal is more.The radio frequency unit that AP can obtain pre-stored first 5GHz allows the wireless terminal accessed
The number upper limit and fractional threshold, then determine the ratio of the first number and the number upper limit, and it is pre- to judge whether the ratio is more than
If fractional threshold.
If the ratio is greater than or equal to the fractional threshold, illustrate the nothing that the radio frequency unit of first 5GHz has accessed
The ratio of line terminal is higher, and load is larger, needs to access wireless terminal by the radio frequency unit of second 5GHz.Then AP can be with
The difference for further calculating the first number and the second number, judges whether the difference is greater than or equal to preset difference threshold, such as
The fruit difference is greater than or equal to preset difference threshold, then illustrates the number of the wireless terminal of the radio frequency unit access of first 5GHz
Mesh is excessive, and the number of the wireless terminal of the radio frequency unit of second 5GHz access is less, and AP can pass through second 5GHz's
Radio frequency unit is by accessing wireless terminal to wireless network.If the difference is less than preset difference threshold, illustrate first 5GHz
Radio frequency unit and the number of wireless terminal of radio frequency unit access of second 5GHz all compare more, AP can continue through the
The radio frequency unit access wireless terminal of the radio frequency unit and second 5GHz of one 5GHz, without carrying out load balance process.
If the ratio is less than the fractional threshold, illustrate the wireless terminal that the radio frequency unit of first 5GHz has accessed
Ratio it is relatively low, load is smaller, and AP is without carrying out load balance process.
It should be noted that if the second number is more than the first number, and the difference of the second number and the first number is more than
Preset difference threshold, then AP can be by the radio frequency unit of first 5GHz by accessing wireless terminal to wireless network.Specifically
Processing procedure is referred to the related description of step 202, and details are not described herein again.
In the embodiment of the present invention, AP can obtain the wireless terminal that the radio frequency unit currently by first 5GHz accesses
Second number of the first number and wireless terminal by the radio frequency unit access of second 5GHz, if the first number is big
It is greater than or equal to preset difference threshold in the difference of the second number, and the first number and the second number, then passes through second
The radio frequency unit of 5GHz is by accessing wireless terminal to wireless network.In this way, working as the wireless of the radio frequency unit access for passing through a certain 5GHz
When terminal is more, AP can access wireless terminal by the radio frequency unit of another 5GHz, to avoid the radio frequency list of a 5GHz
