Abstract :
The paper discusses the quality of service (QoS) requirements for each traffic class in a wireless environment and problems in implementing the QoS requirements in the CDMA based Universal Mobile Telecommunication Service (UMTS) network. In UMTS networks, the medium access control (MAC)/link access control (LAC) sublayer of the OSI layer 2 will be used for priority handling, QoS monitoring, and radio resource management for traffic flows from several users. The paper presents some suggestions to realize QoS requirements in the MAC/LAC sublayer along with restrictions imposed by the W-CDMA air interface
