Seamless handover and QoS provision of applications in converged DVB-H and Mobile IPv6 networks are discussed. The goal is to support efficiently interactive mobile broadcast/multicast services using unidirectional broadcast media (DVB-H) combined with bidirectional mobile access technologies (UMTS, WLAN, WIMAX) in heterogeneous Mobile IPv6 environments. In particular, the focus is: - Handover strategies based on usage of Link Layer Tunneling Mechanisms (IETF RFC 3077) for emulation of bidirectional connectivity of DVB-H access networks in heterogeneous Mobile IP environment; - Network discovery and handover optimization for DVB-H access networks considering IEEE 802.21; - QoS mechanisms of interactive multicast streaming and download services using DVB-H access networks.
