As shown in fig. 6, according to one embodiment of present invention, a kind of message forwarding method based on WDS, including following step
Suddenly：
After STA1~STA6 any one STA successfully manages AP, AP can pass through STA MAC with Action frame
WDS linkup transmits are arrived this MAC by WDS linkup transmits with Action frame again to upper level AP, then upper level AP
His upper level AP.MAC Address is placed in Action frame Vendor Specific IE.
STA6 is successfully associated AP3, and STA6 MAC is sent to AP2 by AP3 by Action Frame, AP2 and then STA6
MAC AP1 is sent to by Action frame.Action Frame are sent on WDS interface channels.
When AP1 upper united mouth sends a message to MAC1 terminal, and MAC1 is not belonging to STA1~STA6.
When AP1 upper united mouth sends message to STA6, then because the AP1 MAC that have received AP2 are notified, then this message meeting
AP2 is transmitted to, similarly, AP2 can be transmitted to AP3.
When AP1 upper united mouth sends message to STA7 (STA7 is not in this network), then because AP1 not have received AC
MAC on STA7 notifies that then this message will not be transmitted to AP2, directly abandons.Bandwidth is so greatly saved.
When STA4 is successfully associated AP2, STA6 MAC is sent to AP1 by AP2.Notice that MAC will not be passed through WDS by AP2 here
Linkup transmit is to AP3.Because AP3 is in AP2 downstream.
When STA and AP disassociations, the MAC of disassociation is equally sent to higher level AP by AP, if higher level AP has
The higher level AP of WDS connections, is handled successively.
Specifically, traditionally, because AP1 does not know MAC1 or not in WDS connections, all AP1 can turn this message
My AP2 is issued, similarly AP2 can also be transmitted to AP3, AP3 will abandon this report due to judging that MAC1 is not belonging to STA5 and STA6
Text.Which results in the waste of Radio Resource.
