Performance Evaluation of Channel Switching Scheme for Packet Data Transmission in Radio Network Controller

Abstract

Abstract. 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 thirdgeneration 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.

Bandwidth Management of WiMAX Systems and Performance Modeling

“…Earlier performance models for 2G wireless networks are based on the Global System for Mobile (GSM) telecommunications for the transmission of voice calls (e.g., [5]) and its extension based on the General Packet Radio Service (GPRS), which allows data communication with higher bit rates than those provided by a single GSM channel (e.g., [4] [6] [7][8]). Moreover, the performance models of the wireless third generation (3G) multiservice Universal Mobile Telecommunication Systems (UMTS) for multimedia traffic flows, such as voice calls, streaming media and data packets, have been of major interests for mobile network providers and have received widespread attention in the literature (e.g., [9] [10] [11]). Recent performance evaluation studies in the field are very often based on simulation modeling and the numerical solution of Markov models [5] [11].…”

“…More specifically, it can be observed in Figs. [9,10] that the analytically established mean number of streaming media and data packets deteriorate rapidly with increasing external interarrival-time SCVs (or, equivalently, average batch sizes) beyond a specific critical value of the buffer size which corresponds to the same mean number of data packets for two different SCV values. It is interesting to note, however, that for smaller buffer sizes in relation to the critical buffer size and increasing mean batch sizes, the mean number of data packets steadily improves with increasing values of the corresponding SCVs.…”

“…Furthermore, the introduction of the wireless third generation (3G) multi-service Universal Mobile Telecommunication Systems (UMTS) for multimedia traffic flows, such as voice calls, streaming media and data packets, has been of major interest for mobile network providers and has received widespread attention in the literature (e.g., [6][7][8][9]). More recently, fourth generation mobile systems have been proposed, broadly as a collection of different radio networks, which have access to IP based services and where roaming is envisaged to be seamless.…”
