SATIN MULTICAST/BROADCAST ORIENTED ARCHITECTURE AND S/T-UMTS TERMINAL AND NETWORK LEVEL INTEGRATION

This paper discusses three different levels of integration, service, network and terminal level, between T & S-UMTS and how they are related to the customer service requirements, satellite market, and business issues as well as to the terminal cost. It is also explained how the geographical and service complement concepts affected the SATIN architecture definition. Different service coexistence scenarios are described and the corresponding terminal architecture scenarios are proposed. Possible network integration issues are highlighted as well.
