Abstract	IEEE 802.16 defines the air interface standard for fixed/mobile broadband wireless access (BWA) metropolitan area networks (MANs), which is expected to support quality of service (QoS) for real time application such as voice over IP (VoIP). However, three major technical problems that stand in the way are: 1) absence of MAC scheduling for supporting codecs with voice activity detector (VAD); 2) absence of mapping procedure between IEEE 802.16 service flow and network flow; 3) absence of efficient admission control for VoIP. This paper proposes two schemes, statistical UGS and UGS-rtPS combined scheduling, of MAC scheduling, addresses mapping RSVP FlowSpecs parameter into IEEE 802.16 QoS parameter, and devises simple admission control algorithm for VoIP services
