Abstract
The present invention provides a method of controlling Wireless LAN (WLAN) medium access using Pseudo-Time Division Multiplexing (PTDM) to improve the Quality of Service (QoS) of the WLAN. The method includes the first step of a Mobile Terminal (MT) acquiring QoS information, which relates to a voice frame to be transmitted, from an upper layer; the second step of the MT exchanging a frame, including the QoS information, with the AP and being allocated QoS slot (QSLOT) information by the AP; the third step of dividing an RF link section between the MT and the AP by the creation period of the voice frame; and the fourth step of transmitting the voice frame in the creation period of the voice frame using the allocated QSLOT information.
