摘要： The disclosure discloses a method and a system for switching a working mode for a backward compatible broadband wireless network, in order to solve the technical problem of switching between each working mode when various compatible modes based on different channelized sets exist in the broadband wireless network. In the disclosure, an access point (AP) indicates its current working mode by a system configuration message; the AP instructs a non-AP associated with the AP to switch a working mode by a mode switching message or a frame exchange sequence; and the non-AP switches the working mode according to instruction information included in the mode switching message or the frame exchange sequence after receiving the mode switching message or the frame exchange sequence. Through the scheme of the disclosure, a wireless point can be switched between each working mode when various compatible modes based on different channelized sets exist in the broadband wireless network, thereby setting up a broadband wireless network supporting backward compatibility.
