Abstract: A method for exchanging a wireless network management message includes: an access point device receives a terminal management message sent by a terminal, and in a contention-free period, sends a management polling frame to the terminal. After receiving, in a contention-free period, the management polling frame sent by the access point device, the terminal sends a next terminal management message to the access point device. The embodiments of the present invention further provide an access point device and a terminal for exchange a wireless network management message. Because the access point device controls the terminal to send a wireless network management message in a contention-free period, a problem of a conflict in a contention period among a plurality of terminals that have accessed a network is avoided, thereby decreasing time for a terminal to access a network.
