Radio resource management is one of the critical functions for mobile wireless networks. The optimal utilization of network resources and the capacity to fulfill quality of service requirements are key requirements for 3G networks operations. Several burst admission and scheduling algorithms were proposed in the literature but most focus on the use of continuous service bit rates. In this study, we modify two widely cited algorithms to utilize discrete service bit rates. The proposed algorithms, DEDF and DPEDF are compared against the original continuous bit rate counterparts in terms of network throughput, power utilization, and packet discard rate for typical 3G network deployment parameters. Results indicate the use of discrete service rate reduces maximum network throughput and lowers the power utilization. Finally, the study also evaluates the effect of various packet delay thresholds on the overall performance of the network.
