Q3M: QoS architecture for multi-user mobile multimedia sessions in 4G systems

Abstract

Fourth generation systems (4G) will provide multimedia group communication sessions to multiple mobile users with distinct requirements. This way, it is expected the control of the quality level, connectivity and ubiquitous access for multi-user multimedia sessions across heterogeneous and mobile networks with seamless capability. This paper analyses the requirements of a control architecture to provide Quality of Service (QoS), connectivity and seamless handover management for multi-user sessions in 4G systems, and introduces the QoS Architecture for Multi-user Mobile Multimedia (Q3M) proposal. In addition, simulation results present the efficiency of this approach concerning the session setup time and packet losses during handover.
