The future third generation mobile communications system, named IMT-2000, is expected to provide mobile users with voice, high-rate data and their combined multi-media services with the same QoS as in the fixed networks. As a radio access standard for the IMT-2000, W-CDMA and cdma2000 have been selected in Europe and North America, respectively. In this paper, we present an analytic model of the cdma2000 data mobile servicing a connected data service. In order to do this, we first model the traffic generated at mobile by a discrete-time Batch Markovian Arrival Process (D-BMAP). Next, we model the Radio Link Protocol (RLP) Queue in the cdma2000 MAC protocol by a D-BMAP/D/1 queueing system with batch service and setup times. Finally, we analyze this queueing system and get the performance measures such as the mean delay and the loss probability. Analytic results are compared with simulation ones for accuracy.
