Effects of traffic characteristics on the General Packet Radio Service (GPRS) performance

Luc Brignol; Jerome Brouet; Patrick Charriere; Francoise Mercier

New evolutions of GSM are giving an increasing part to data transmission. In this respect, GPRS system has been developed to provide an efficient end-to-end packet transmission on GSM. However, a unique protocol is provided by GPRS for all the types of data traffic. This paper analyzes the different bottlenecks of the GPRS system for three typical data traffic in severe input load conditions. It shows that depending on the data traffic type, distinct parameter setting should be considered for achieving optimal performance.
