Claim Text:
1. A method for implementing load balancing, comprising: when a first Access Point (AP) is to transmit data received from a Station (STA) which has accessed the first AP, determining whether itself is overloaded; determining, by the first AP, other APs for load sharing when determining that itself is overloaded; and offloading, by the first AP, the received data to said other APs; wherein the determining by the first AP other APs for load sharing comprises: way 1, receiving, by the first AP, Beacon frames of said other APs, extracting loads of said other APs in Beacon frames; or way 2, broadcasting, by the first AP, a load balancing request to said other APs, and receiving load balancing responses by said other APs; wherein the method further comprising: in way 1, adding a load of a wireless AP into a standard Beacon frame so as to be broadcasted by adding the load of the wireless AP into a Frame Body field of the standard Beacon frame; in way 2, reconstructing a Sub Type field of the standard Beacon frame to form a special frame for broadcasting a load balancing request of the wireless AP, parsing, by a wireless AP receiving a reconstructed Beacon frame, the reconstructed Beacon frame and returning a load balancing response according to a structure of the reconstructed Beacon frame; wherein the load of the wireless AP is added into a Frame Body field of the load balancing response.
