Be explained in detail to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
Embodiment one:
As shown in Figure 2, the main flow chart of the load-balancing method of a kind of WLAN (wireless local area network) that provides for the embodiment of the invention one, the method is applied to STA and successfully accesses after the AP, executive agent can be AC(Access Controller, Radio Access Controller), the method specifically may further comprise the steps:
Optionally, the signal access intensity level of this AP that this access information can detect during AP in access for this STA, this step can specifically comprise so: judge that whether the signal access intensity level of this AP that this STA detects when access AP is less than default signal strength signal intensity roaming threshold value, when judged result when being, then this access information satisfies default roaming conditions.
Optionally, this access information also can access quantity for the user of this STA this AP when accessing AP, this step can specifically comprise so: judge this STA access during AP the user of AP access quantity and whether access quantity roaming threshold value greater than default user, when judged result when being, then this access information satisfies default roaming conditions.Wherein, the user accesses quantity roaming threshold value and arranges according to practical application request, is not restricted at this.
Whether step 23 judges the load of this AP greater than default load threshold, when judged result is, and execution in step 24, otherwise do not process.
Why satisfy under the prerequisite of default roaming conditions at the access information of judging this AP, go again to judge that whether the load of this AP is greater than default load threshold, be for only guarantee to those access AP and signal strength signal intensity a little less than, the STA that the signal that namely is in this AP covers the edge carries out follow-up operation, and has guaranteed that also the communication of the STA that those access AP and signal strength signal intensity are stronger is unaffected.
Need to prove that load threshold default in the embodiment of the invention can arrange according to practical application request, is not restricted at this.
Optionally, can also obtain simultaneously the load information of other AP except the AP of its access that detected by STA; Also can obtain the current demand signal intensity level of other AP except the AP of its access that detected by STA.
Wherein, the signal access intensity level of the AP of its access that detects during at access AP as the current signal strength values of the AP of this STA access that compares above-mentioned acquisition and this STA of obtaining in advance is equal, then according to the load information of other AP that detected by this STA that obtain in the step 24, from other AP, choose the AP of a least-loaded;
During the signal access intensity level of the AP of its access that detects during at access AP less than this STA that obtains in advance when the current signal strength values of the AP of this STA access that compares above-mentioned acquisition, illustrate that this STA moves after this AP of access, and be to cover fringe region to the signal of this AP to move, then the signal according to the current demand signal intensity level of other AP except the AP of its access that detected by STA that obtain in the step 24 and other AP that detected when the access AP by this STA of obtaining in advance accesses intensity level, determine the AP that signal strength values increases, and from the AP that the signal strength values of determining increases, choose the AP of a least-loaded.
Concrete, when the transmitted power of the AP that chooses is rated maximum, can controls the AP that this STA accesses and reduce its transmitted power, so that AC can receive the connection request of the AP that access that this STA sends is chosen;
