Abstract
The present invention applies management frame defined in IEEE 802.11 standard to a wireless distribution system (WDS) mode by adding an information element (IE) into the management frame, which enables any access point (AP) in WDS to maintain IE based on its own setting and state, then send IE via the management frame for providing state of the AP under WDS mode, determine whether a physical link (i.e., a wireless link between APs) should be established therewith based on received IE, and maintain the established physical link through the wireless management frame in a real time manner. Thus, the existence and necessity of the physical link between different APs in WDS can be determined correctly.
