In this paper, we evaluate the capacity of voice over internet protocol (VoIP) services on high-speed downlink packet access (HSDPA), in which frame-bundling is incorporated to reduce the effect of relatively large headers in the IP/UDP/RTP layers. Also, the capacity of VoIP service on HSDPA is considered in a mixed voice and best-effort traffic scenarios. In order to guarantee QoS for VoIP service, a design of packet scheduler based on the proportional fairness scheme is provided. Simulation results show that performance of VoIP service with frame-bundling scheme is highly sensitive to delay budget. We also conclude that the capacity of VoIP service on HSDPA is attractive for transmission of voice, if compared to the circuit switched voice and to the VoIP on WCDMA used in Release¿99.
