Simple QoS provisioning framework for MBMS in all-IP UMTS networks

The rapid development of high bit-rate mobile and wireless networking architectures offers a wide range of novel multimedia-based applications and services. The efficient delivery of these services requires mechanisms of broadcasting and multicasting, while the increasing user expectations require quality of service (QoS) support. When IP datacasting has been seriously considered in mobile and wireless networks, soon has appeared the idea of multimedia broadcast-multicast service (MBMS) for universal mobile telecommunications system (UMTS) environments. In order to extend the QoS capabilities of MBMS in all-IP 3G networks and beyond, we introduce a simple QoS provisioning framework feasible for any policy-based architecture. In this paper we also evaluate our proposal using a lightweight UMTS/MBMS simulation model implemented in OMNeT++.
