A Fair Queueing Algorithm is proposed for data services in an integrated voice/data CDMA system. After delay-sensitive voice users are allocated first, then residual resources are allocated to data users according to the throughput maximization strategy. In order to fairly allocate data users, power resource concept is used which considers the BER and the rate requirement of data users, and apply WFQ (Weighted Fair Queueing) to CDMA systems with consideration of a GPS fluid-flow model. In order to implement this fair resource allocation scheme, a virtual clock for short-term fairness and a credit table method for long-term fairness are used. Based on these concepts, this paper proposes WFQS (Weighted Fair Queueing with State Control).
