Abstract

In this work, we evaluate the performance of voice over Internet protocol (VOIP) services over high speed downlink shared channel (i.e. UMTS-HSDPA), that is used in third generation cellular systems to provide a high speed packet data service. We focus on examining system outage based on delay budget in radio access networks. We conclude that VOIP system performance is highly sensitive to delay budget. In order to support VOIP services with end-to-end delay comparable to that of circuit switched voice, the HS-DPA system needs to be carefully engineered, and design alternatives that relax the delay budget in radio access networks could be considered.
