“…From [6], voice, web-browsing and data services are usually assumed to be on/off sources. Comparatively, video is usually modeled as a two-dimensional discrete-state, continuous-time Markov chain [7]. The main contribution of this paper is to analyze the outage probabilities for multi-connection multidass services within all mobile users in the uplink of a wideband CDMA cellular mobile network.…”

Abstract. In this paper, we address the data link layer quality of service (QoS) issue by investigating the outage probabilities for multi-connection multidass services in the uplink of a wideband CDMA cellular mobile network. Four Universal Mobile Telecommunications System (UMTS) QoS classes are served within each mobile user simultaneously. Each class has different QoS constraints. Assuming perfect power control, a power allocation scheme is designed to fulfill the desired received powers for all traffic classes. The outage probability is formulated for each mobile user with its traffic classes in terms of bit error rate (BER) and signal-to-interference-plus-noise ratio (SINR). In addition, an admission region, satisfying the outage probability requirements of all mobile users, is computed. lntroductionIn UMTS network, wideband CDMA technology enables multimedia services with different QoS specifications. In [1], four different QoS traffic classes, including conversational, streaming, interactive and background classes, are defined for 3G systems. The network is responsible for providing different QoS guarantees to all traffic classes. QoS attribute at the data link layer, such as outage probability, attracts a Iot of research interest. In [2], Gilhousen et al. studied the outage probability issue for a single class on/off source in a CDMA network. Recently, Wong et al. extended the analysis of outage probability from a single class sources to on/off multidass sources, variable bit rate (VBR) multidass sources and video multidass sources in [3], [4] and [5], respectively. However, each mobile user can only have a single connection in these papers. This paper differs from the existing published work [3][4][5] by dealing with QoS provisioning for each mobile user having multiple traffic classes. In this analytical work, each user can have multiple connections to serve more than one traffic class. According to [1,6], voice, video, web-browsing and data services are chosen as typical examples of conversational, streaming, interactive and background classes in the UMTS QoS architecture, respectively. From [6], voice, web-browsing N.

“…l(b) According to Sen's model [7], each video source can be decomposed into one high-bit-rate (HBR) and M low-bit-rate (LBR) mini-sources, which are identified by HBR and LBR spreading codes, respectively. Thus, the activity factors of LBR and HBR mini-source are given by…”

A n interactive video-on-demand (IVoD) system consists of a video server and a client connected together through a high speed network. Use of interactive video-on-demand in an educational environment is very interactive because students frequently pause, fastforward, skip and view frame-by-frame. Designing a network able to support interactivity and make e cient use of bandwidth is challenging. In this paper we evaluate the suitability of a number of congestion control schemes (based on the service categories of ATM) for carrying interactive video on demand. We have developed analytical models to evaluate and compare the various schemes. Data on interactive behaviour of students obtained from IVoD trails carried out in our laboratory have been used in the models. We show that the renegotiated constant bit rate service category has considerable potential for carrying IVoD over a high speed network, such as the asynchronous transfer mode (ATM). We also show the use of an application layer, (such as Winsock 2), by the server to limit congestion within the network.
