Abstract：The 3G based GEO satellite mobile communication system has become a major satellite mobile communications development trends along with technologies’ maturity and customers’ growing traffic needs. As we can see, the traffic model of the system is the basis for system construction and implementation. This paper proposes a kind of 3G based GEO satellite mobile communication systems architecture model, studies system end-to-end application layer service, models different types of traffic using structure method, and conducts performance simulation in according to designed parameters. The simulation results show that the characters of 3G based GEO satellite mobile communication systems traffic
