摘要

A method and apparatus for a wireless network to maintain a QoS is provided. The apparatus includes a resource calculating unit (110) which calculates resources needed to transmit packets if a transmission rate of a network changes, a comparing unit (120) which compares the calculated resources and resources allotted by an access point of the network; and a control unit (130) which determines whether to request additional resources by using a result of the comparison by the comparing unit (120).
