A single cell model for the performance analysis of the radio layer in GSM phase 2+ (GPRS) networks under voice and data traffic

摘要

Classically cellular networks have been analysed using Poisson call arrivals and negative exponential channel holding times. This approach has been reasonable for the circuit-switched voice traffic carried by the earlier cellular networks. However, with the advent of GPRS networks, packet switched data traffic now competes with circuit-switched voice traffic for the available resources on the air-interface. We analyse the merging of voice and data traffic in the radio layer of the GSM Phase 2+ (GPRS) networks.
