Claim:
A method of setting up Quality of Service (QoS) in a wireless communication system, the method comprising: during an initial network entry, creating at least one static Service Flow (SF) by receiving a QoS profile from a Base Station (BS); if a QoS change is requested for the SF, transmitting, by a Mobile Station (MS), to the BS a service change request message including QoS change information; and by the BS, determining if the QoS change information is admitted, and, if admitted, transmitting a service change response message to the MS, and changing a QoS of the SF, wherein the QoS profile is originated from a WiBro System Manager (WSM) and the at least one static SF is determined to be statically allocated to the MS by an Authentication, Authorization, and Accounting (AAA) server, and wherein the QoS change is determined whether to be allowable by at least one of a Network Entity (NE) and an Access Service Network-GateWay (ASN GW) and the determination result is transmitted to the BS.
