The topic of this paper is the evaluation of the impact of data traffic composition on GPRS performance. A detailed statistical analysis of GPRS traffic per service at different levels has been carried on live measurements. A multi-service performance model is presented in order to derive simple and closed form formulas, associating capacity, traffic characteristics and performance. This performance model allows the analysis of the impact of a mix of the applications (WAP, Web, e-mail, etc?) on the quality of service QoS offered to GPRS users. It also gives the opportunity to evaluate the impact of the introduction of new services on the QoS offered to already existing services.
