Simulation study of integrated data/voice services in high speed packet radio network

By simulation, this paper studies the performance of integrated data/voice services in the high speed packet radio network and thoroughly discusses the influence of different low layer protocols on the performance of services and the network, on the basis of which some new low layer protocols to support integrated data/voice services are presented. Simulation results show that low layer protocols play an important role in the performance of the network and the protocols presented significantly improve the performance of data/voice integration. Even in case of heavy load, our protocols can provide acceptable quality of voice service for a limited number of users.
