Abstract

In this paper, we present a performance analysis of an integrated voice/data access system in a GSM/GPRS network, where the radio channels are subject to transmission impairments. Circuit-switched GSM voice and packet-switched GPRS data users share the N channels, with priority given to voice. We incorporate transmission impairments by a Markovian two-state channel model, where one state is characterized by a very low BER (good state), and the other by a much higher BER (bad state). The results indicate that the delay performance of the GPRS data users can be drastically affected by the channel impairments
