We investigate the packet-scheduling function within the access scheme of a unidirectional satellite system providing point-to-multipoint services to mobile users. The satellite system may be regarded as an overlay multicast/broadcast layer complementing the point-to-point third generation (3G) mobile terrestrial networks. The satellite access scheme(More)
This paper proposes a complete satellite access network solution for multimedia broadcast multicast service (MBMS) delivery based on the T-UMTS standards. Firstly, the benefits of MBMS delivery via satellite (SAT-MBMS) for both S/T-UMTS network operators are shown via market and business analysis. A new integrated S/T-UMTS architecture for MBMS delivery is(More)
This paper proposes a Radio Resource Management strategy for unidirectional satellite systems delivering multicast and broadcast services to mobile users. Both the radio interface and the targeted services impose particular requirements on the RRM task. We present the individual RRM entities, describe their exact role and suggest algorithms for their(More)
The advantages of satellites in multicast and broadcast service provision has attracted a lot of interest within the satellite community and motivated a re-examination of the role of mobile satellite systems with regard to terrestrial networks. This paper reports on the approach taken by the IST project SATIN towards the definition of a suitable(More)
Efficient support of Internet-based applications to mobile/nomadic users is a key feature of the thirdgeneration (3G) networks. In light of the shortage and the high cost of the T-UMTS spectrum, the operators are looking into the provision of integrated broadcast/multicast services through hybrid broadcast-UMTS systems. S-UMTS could play an important role(More)
