This paper discusses progress made in cellular systems, satellite systems, and the networking between them. The functionality of the cellular system and the satellite system is explained, followed by a description of a simulation study involving the hand-off aspect between the cellular and satellite systems. Within the description of the simulation study, the system roles and relationships are described. The main performance issue at hand is the delay to setup a call handoff. The study serves also for developing a model in which a hybrid network intersystem operation can be studied.
Final results show the types of analysis that the model can be used to determine.
