QoS-enabled broadband mobile access to wireline networks

Abstract

Third-generation wireless systems, known as IMT-2000 within the ITU, offer opportunities to support a wide range of multimedia services. Packet data services will play a major role in these new multimedia services. A key component of packetized data services is to ensure end-to-end QoS requirements through efficient management of the network's resources. In this article we present an overview of radio resource scheduling schemes including architecture, radio interface protocol, and interactions in a wide-band CDMA environment. We then present an example of QoS architecture followed by a discussion on end-to-end provisioning and inter-working from wireless to fixed networks.
