In actual applications, a kind of concrete implementation is, if the total channel utilance separately of the access point in N number of BSS network is all greater than preset utilance threshold value, the access point access that non-APSTA selects total surplus channel capacity maximum from the access point N number of BSS network.A preset utilance threshold value can be realized scene by concrete and set, can be set by non-APSTA, such as, can set utilance threshold value is 0.2*255=51, then, when the total channel utilance of the access point in N number of BSS network is all greater than 51, the access point access that non-APSTA selects total surplus channel capacity maximum.

The method of the access access point that the embodiment of the present invention provides, non-APSTA can calculate the total surplus channel capacity of each AP, thus the access point that total surplus channel capacity can be selected maximum access, balance the load between each AP, ensure that the service quality communicated between non-APSTA and AP simultaneously.

If the minimum value in the total channel utilance of the access point in 302 N number of BSS networks is less than preset utilance threshold value, the access point access that non-APSTA selects total channel utilance minimum.

In embodiments of the present invention, after non-APSTA receives the respective total channel utilance of N number of AP broadcast, judge whether the minimum value in N number of channel utilization is less than preset utilance threshold value, the access point that if so, non-APSTA selects total channel utilance minimum accesses.A preset utilance threshold value can be realized scene by concrete and set, can be set by non-APSTA, such as, can set utilance threshold value is 0.2*255=51, then, when minimum value in the total channel utilance of the access point in N number of BSS network is less than 51, the access point access that non-APSTA selects total channel utilance minimum.The method of the access access point that the embodiment of the present invention provides, the access point access that non-APSTA selects total channel utilance minimum, can balance the load between each AP, ensure that the service quality communicated between non-APSTA and AP simultaneously.

Next introduce the method for the another kind access access point that the embodiment of the present invention provides, as shown in Figure 4, comprising:

401, the AP in BSS network obtains the total channel utilance of this AP.

In actual applications, a kind of attainable mode is, AP, according to the occupied time of channel in timing statistics, the number of beacon frame sent in timing statistics, the gap periods duration of transmission beacon frame, calculates total channel utilance.

In embodiments of the present invention, the AP in BSS network can obtain its total channel utilance by BSSLoadelementformat as shown in table 1.

In actual applications, ChannelUtilization is total channel utilance, is specifically as follows the expression formula (5) described in previous embodiment:

$\mathrm{ChannelUtilization}=\mathrm{Integer}\left(\frac{255*\mathrm{channelbusytime}}{N\_\mathrm{beacon}*P\_\mathrm{beacon}*1024}\right)$

Wherein, the number of beacon frame (English for beacon) of N_beacon for sending in timing statistics, P_beacon is the gap periods duration sending beacon frame.

If 402 total channel utilances are greater than preset utilance threshold value, the value of total channel utilance is revised as utilance thresholding by AP, and sends to the non-APSTA in this BSS network.

In embodiments of the present invention, a preset utilance threshold value can be realized scene by concrete and set, can be set by AP, such as, can set utilance threshold value is 0.8*255=204, then, when ChannelUtilization is greater than 204, the value of ChannelUtilization is revised as utilance thresholding by AP, wherein utilance thresholding specifically has AP to set according to concrete application scenarios, can be such as 255 by utilance threshold sets, 255 is a maximum utilance thresholding, and send to the non-APSTA in this BSS network, after the value receiving total channel utilance is the channel utilization of 255, this AP is no longer accessed to make non-APSTA, the load between each AP can be balanced, ensure that the service quality communicated between non-APSTA and AP simultaneously.
