In order to achieve global roaming of UMTS users, the satellite segment is integrated in the UMTS terrestrial radio access network and it replaces a terrestrial Node B. As the satellite capacity to support a big number of users at the same time is high, terrestrial RNC will just support one satellite/Node B instead of several terrestrial Node B, meaning a gain in coverage. Our proposal is to study the capacity of USRAN (UMTS Satellite Radio Access Network) for mixed traffics sent over satellite channel in order to achieve dimensioning that can be usedfor call admission control. The interest of such a study is to give the possibility of USRAN dimensioning, i.e., to determine the capacity neededfor a number offlows given by the operator. In this paper we describe the network architecture for satellite integration with UMTS Terrestrial Radio Access Network. Performance analysis and testing were donefor voice traffics represented by an ONIOFF source model as well asfor data transfer application.

-Quality of Service (QoS) of disadvantaged networks is usually considered from a purely network standpoint in existing works. Adversarial intervention in such networks is not analyzed, nor is it possible to infer if a QoS loss is benign or otherwise. In this work, we analyze the nature of a QoS loss between a remote system and a backend service infrastructure connected over a disadvantaged satellite network. We present a game theoretic framework to infer if a QoS loss is due to benign or malicious factors. An attack on the backend system (DDoS attack) or on the transmitting station (RF Jamming) is considered to be a malicious factor, while a statistical network variation due to random noise is considered to be a benign factor. We then present the implementation of the game theoretic framework to the satellite network, and verify the validity of the idea through simulations in OPNET.
