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

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.
