Feasibility of Frequency Sharing in Satellite/Terrestrial Integrated Mobile Communication Systems

Abstract

Satellite and terrestrial integrated mobile communication systems have been recently drawing a great deal of attentions, where a terrestrial network and a satellite network supplement each other to enable ubiquitous communications economically. In such an integrated mobile communication system, a small hand-held mobile terminal can be used in both satellite and terrestrial networks in a seamless manner. One of the key challenges of the satellite and terrestrial integrated mobile communication system is to share frequency spectrum by satellite networks and terrestrial networks, aiming at efficient frequency utilization and easy implementation of small size satellite/terrestrial dual mode mobile terminal. This paper proposes a simple system model to study the feasibility of frequency sharing between satellite and the terrestrial networks. The evaluation results show that the frequency sharing between satellite and terrestrial networks is feasible with careful network design and traffic control.
