W-CDMA (Wideband-CDMA) is expected for the radio access technology of the third-generation mobile telecommunication systems. In the second-generation systems, voice traffic from each user has mainly been transmitted via the dedicated transport (radio) channel. In addition, the third-generation systems will efficiently accommodate data traffic based on the packet transmission in the shared common transport channel. Therefore, data traffic can be transmitted via one of two types of channels: i.e., dedicated channel and common channel. However, the channel selecting/switching scheme in RNC (Radio Network Controller) has not been standardized. Thus, in the present paper, we will propose some channel switching schemes and evaluate their performance in terms of the packet loss probability and the utilization of dedicated channels by means of simulations.
