Abstract: One of the key issues in the next generation wireless cellular networks is to support multiple services, in which call admission control policy has to guarantee the different Quality of Service (QoS) requirement from diverse applications, and at the same time ensure the scarce bandwidth be utilized efficiently. In this paper, we first build upon our proposal Dual Threshold Bandwidth Reservation (DTBR) scheme to integrate more realistic, variable data traffic, and them proceed to analyze the DTBR scheme using two-dimensional Markov process. Both analysis and simulation results indicate that, by keeping target handoff voice call dropping probability, adoption of elastic data traffic model can reduce handoff voice call dropping probability and improve overall system award; by adjusting the threshold values in the DTBR, we demonstrate that it is capable of satisfying different QoS requirements for voice and data traffic while achieving the maximum utility.
