This paper proposes a method for system performance modeling of a shared voice and packet data channel. 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.
