The IST ARROWS (Advanced Radio Resource Management for Wireless Services) project aims at providing Radio Resource Management (RRM) and Quality of Service (QoS) management solutions for the support of integrated services in the Universal Terrestrial Radio Access (UTRA). The project addresses packet access, asymmetrical traffic and multimedia services, all based on IP. Among others, a multimedia testbed was developed to validate the proposed concepts. Although ARROWS concentrates on the QoS aspects of UTRA, a global QoS framework was found necessary for two reasons. First, from the applications point a view, QoS is an end-to-end issue and, second, a mapping between UMTS and end-to-end QoS parameters is required.
