Abstract :
This paper presents the results of a quality of service (QoS) study for the VoIP service over 3G WCDMA networks. An end-to-end simulation platform has been used for this purpose. The simulations have been using an adaptive multi-rate (AMR) speech codec at 12.2 kbit/s with combination of RTP, UDP and IPv6 protocols. The simulated transmission path includes two radio links (uplink and downlink), connected with a packet switched core network and UTRAN radio access networks with several different radio transmission conditions. Furthermore, robust header compression is applied in both radio links. The results include buffering statistics, end-to-end delay estimates, and packet loss statistics.
