Abstract :
The quality-of-service (QoS) requirements of typical mobile packet data applications are very diverse. QoS profiles of the General Packet Radio Service (GPRS) are defined using the parameters service precedence, reliability, delay, and throughput. A one-dimensional decomposing Markov chain is used as the queueing model to analyze the GPRS performance in terms of the mean delay and 95% delay. In addition, the impact of buffer assignment and guard channels on the GPRS traffic is also investigated. The analytical results are verified by simulation and the comparison shows that they are very close.
