This paper proposes a method for system performance modeling of a shared voice and packet data channel. In this paper, we investigate and simulate the impacts of system configurable parameters on data user perceived channel performance, as well as call blocking rate for a voice user. Two types of voice traffic are simulated including half rate AMR and full rate EFR. The simulation results are useful for a service provider to configure the EDGE channel to meet the QoS requirements to serve both voice and data traffic.
