Abstract

Common packet channel (CPCH) access is an efficient approach to support packet data transmissions in a wideband code division multiple access (W-CDMA) system. This paper investigates a modified CPCH access method which provides prioritized services for various traffic classes. Each traffic type has a distinct transmit permission probability that is estimated at the new call initiation stage based on the status of CPCH channel occupancy. The differentiated service qualities are evaluated in terms of packet blocking rates. The overall system performance is also evaluated in terms of throughput.
