Support of interactive QoS based services in hybrid broadcast and mobile IPv6 environment

Abstract

Mobile terminal receivers with unidirectional network interfaces are not considered as a special case in the standardization of Mobile IPv6. For the interaction of unidirectional access technologies (DVB-H, DVB-T) and mobile networks (UMTS, WLAN, WIMAX) in heterogeneous IPv6 environment, there is a challenge for unified mobility and QoS management technologies supporting new interactive broadcast services, such as IP Datacast. This paper discusses protocol enhancements of Mobile IPv6 in order to support interactive QoS based multimedia services in hybrid broadcast and mobile IPv6 environment. Interaction of the Link Layer Tunnelling Mechanisms (RFC 3077) with the Mobile IPv6 and Fast Handovers based on "reverse tunnelling info" is used to provide uniform handover support for broadcast and mobile IP services. QoS management for broadcast access Internet network environment is proposed based on resource reservations for the two directions - downstream connection of the un idirectional broadcast network and return tunnel using wireless access network. QoS information base describing the capabilities of the unidirectional access networks and the IP return tunnel network ("feed") is used for enhanced QoS support of interactive services

Integration of the digital broadcast mobile television network and the 3G network

“…Evolved Packet System -EPS). U (Miloucheva, et al, 2007) je predloženo unapređenje verzije 6 mobilnog IP protokola (engl. Internet Protocol version 6-IPv6) da bi se podržale interaktivne multimedijalne usluge sa zahtevanim kvalitetom u hibridnom radio-difuznom i mobilnom IPv6 okruženju.…”

Reliable Multicast Transport for Heterogeneous Mobile IP environment using Cross-Layer Information

“…In DAIDALOS architecture, a particular focus are scenarios for reliable on-demand content delivery (video, audio, data) in heterogeneous mobile IPv6 environment including broadcast (DVB-H) and mobile networks (UMTS, WIMAX, WLAN) [32].…”

“…The proposed reliable multicast framework (fig. 1) involves a flexibly configurable tree based reliable multicast protocol for fixed core and mobile access network infrastructures using localized retransmission schemes [32]. Based on the mobility requirements, the retransmission schemes are classified in:…”

“…When satellites or unidirectional broadcast media (DVB-H, DVB-T) are used, then the NACKs from the receivers to the sender in the unidirectional network environment can be sent. It is done using an IP tunnel established by means of additional bidirectional access network using the link layer tunnelling mechanisms [35].…”

“…The trends in mobile TV are to provide new enhanced experience in delivering movies and television programs to fixed and mobile users combining video streaming with VCR (Video Cassette Recorder) functions [35]. Interactive mobile TV scenarios are based on:…”
