Performance Analysis of GPRS Data Services
Min Fan-bao · Dianzi xuebao · 2004
A D-BMAP/D/1 queuing model is applied to analyzing the performance of GPRS data services,such as mean RLC/MAC queue length,mean delay and loss rate of mini-packets,in which a simplified one-phase access procedure and different service rate are taken into account.The analysis results show that:Delay and loss rate are reduced with longer timer T 3182;Delay is increased under the greater probability with which mobile station in the idle state generates new session;Loss rate is decreased with larger buffer size.But delay is changed unclearly with the number of packet calls in a session.
