Performance analysis and modelling of an OSA gateway

In English It is foreseen that you in the future should be able to use the same services independent of where you are positioned or which terminal that is used. The open service architectures provide these opportunities. Open Service Access (OSA) is an example of such an architecture and it is part of the specification delivered by 3GPP. This paper explains the OSA architecture and presents a model of an OSA gateway. Further, it discusses and proposes some feasible overload control mechanisms for the gateway. The behaviour of the mechanisms is investigated through simulation.
