A method for communication in a wireless LAN, the apparatus and system

The present invention discloses a method, apparatus and system for communicating wireless LAN types, the method comprising: acquiring association identifier for the access point AP site assignment; to establish a correspondence between the address information of the station associated with the identification , according to the corresponding relationship to the relay station and the AP providing a communication service. WLAN communication method of an embodiment of the present invention, by providing a relay device between the relay station and the communication service access point AP, and AP is the allocation system associated with the site identification, thus avoiding each relay device respectively assigned identifier associated with its management of the site, and to ensure the relevance of the site within the basic service set identifier of the AP does not conflict, which has facilitated the subsequent communication process between the AP and the site, improve the communication efficiency.
