Abstract
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 in the efficient delivery of some UMTS services to which it is better suited. These services include broadcasting and multicasting applications such as audio/video, e-newspaper and live stock exchange data. The level of IP penetration into 3G networks is a decisive factor for the design of an efficient system, optimized for the delivery of these services. The paper identifies the respective requirements arising for the S-UMTS air interface, in the frame of the architecture scenarios envisaged within the EU IST project SATIN.
