Study of the Impact of UMTS Best Effort Parameters on QoE of VoIP Services

This paper evaluates the performance of VoIP services over mobile accesses, with special focus on currently deployed Best Effort UMTS networks. There are different configuration parameters that have a great impact on end users' perception of quality. This paper tries to help understanding the impact of those parameters, and how they can be tuned for a better VoIP experience.
