A Functional End-to-End QoS Architecture Enabling Radio and IP Transport Coordination

Abstract — This paper presents a novel end-to-end Quality of Service (QoS) architecture for wireless networks. The focus is placed in the coordination of QoS management between Common Radio Resource Management (CRRM), for heterogeneous radio access technologies, and the QoS enabled IP-based network segments. A functional reference QoS framework is introduced and the envisaged QoS management functions are described. The innovations proposed in the presented QoS framework arise mainly from the study of cross effects between the radio and fixed transport resources management. The proposed QoS framework has been designed considering the current 3GPP R6 networks as well as their long-term evolution (LTE) scenario. Some illustrative results for a coordinated admission control algorithm are given as a proof of concept, to show the advantages of CRRM and IP QoS management coordination.
