Performance Analysis of GSM-GPRS Network

"To provide Internet Services with much better utilization of frequency spectrum the General Packet Radio Service (GPRS) is integrated in a GSM network. However, some questions to arise about the network performance when these networks are integrated, once that they share the same radio resource of the air interface. Hence, on this article an analytic model is developed using the M/M/c/c queue, which is used to analyze the integrated GSM-GPRS network. That model is based on the voice services pre-emption over the Internet services to provide measures that inform the availability of radio resource, and this way, the throughput of the GPRS to any offered voice traffic profile on the GSM network."
