Abstract: PURPOSE: A wi-media resource reservation method for constructing a wi-media network is provided to reserve other links by passing through a relay device or a direct link. CONSTITUTION: When data is transmitted and received in an MAS(medium access slot) S-R(S518), a DRP(distributed reservation protocol) IE(information element) for a reservation target node set as a reservation detail state code of a relay notification is confirmed(S522). It is determined whether the data is transmitted and received through an MAS R-T(S524). When a relay node is able to use the MAS S-R and the MAS R-T, MAS R-T information for continuously transmitting the data is stored(S526). The DRP IE set as a relay approval reservation state code is transmitted to a reservation subject node(S528).
