Titel
On call admission control and handover management in multimedia LEO satellite systems
Abstract
Low earth orbit (LEO) satellite systems gained considerable interest in the past decade and were expected to be instrumental in future telecommunications systems. Nevertheless, the first two LEO satellite networks that are currently in operation have not come to fruition on account of the limited spectrum of services that they provide. In this context, future LEO satellite networks will be geared towards the provision of multimedia services. In this paper a novel call admission control and inter-satellite handover management scheme tailored for multimedia LEO satellite systems is proposed and evaluated. In addition, the proposed scheme is examined in satellite diversity based systems and two different satellite selection criteria, which can be applied to both new and handover requests, are assessed.
