Provided are a wireless local area network (LAN) network, a mobile station and a base station, and a method of controlling handoff in the wireless LAN network. The wireless LAN network includes a mobile station and a number of base stations. The mobile station notifies a previously connected first base station of an entry into a power-save mode, performs a handoff process with a second base station, and then notifies the first base station of an exit from the power-save mode. Each of the base stations buffers a packet to be transmitted from a public network to the mobile station when the each of the base station is notified of the entry into the power-save mode by the mobile station, and transmits the buffered packet to the mobile station when the each of the base station is notified of the exit from the power-save mode by the mobile station. This wireless LAN network system and method is capable of performing handoff without packet loss.
