Abstract

GPRS is designed for transmitting packet data and supposed to take its radio resource from the pool of channels unused by GSM voice services. The number of channels allocated to GPRS is a random variable depending on the voice traffic. In this paper, an approximation method is used for evaluating the GPRS performance of single-slot service in the variable radio resource. The method could be used for evaluating the GPRS performance when the average service time of circuit switched services is much longer than that of GPRS. The multi-slot services cause higher blocking probability and longer delay to the network than the single-slot service. However, those effects can be reduced by implementing a GPRS resource allocation scheme with flexible multi-slot services
