“…Let us consider the simplified case where a cell is approximated by the rectangle in Fig.1, an assumption widely used in the literature ( [2], [3], [6]). DDBHP defines a time interval, called time threshold (t T H ), prior to handover occurrence.…”

“…In order to derive a model for the analytical study of the proposed method, the concept of "street of coverage" [14], [2], [6] is adopted. It refers to a region covered by satellites in the same orbital plane and can be extended to represent a succession of cells ( [6]).…”

“…Nevertheless it introduces delay and relatively high forced termination probability if the acceptable queueing delay is low. In [2] E. Del Re et al proposed a handover prioritization scheme for different channel allocation techniques. This scheme proposes the queuing of handover requests (QH) for a maximum time interval in case there is no channel available in the destination cell.…”

Abstract-The problem of dynamic handover management in Low Earth Orbit (LEO) satellite systems is addressed in this paper. Particularly, an analytical study of a newly proposed method for handover management, called Dynamic Doppler-based Handover Prioritization scheme (DDBHP), will be presented. DDBHP utilizes Doppler shift monitoring of each communicating user terminal onboard the satellite and geometric characteristics to accurately predict the handover load. As a result, handover requests are more effectively managed, resulting to an improved performance in terms of blocking and forced termination probabilities. Moreover, by supporting guaranteed handovers, DDBHP can be used to provide QoS to users of future broadband satellite networks. An extensive mathematical model that justifies Doppler shift monitoring will be presented along with a detailed queueing model used not only to evaluate DDBHP performance but also to provide a methodology for associating DDBHP operational parameters with desired performance. Comparison of analytical and simulation results validate the proposed model.

Abstract. Dynamic Channel Allocation (DCA) techniques permit a high resource utilization in cellular networks and are able to adapt themselves in the presence of rapid variations of traffic loads offered to the cells. Therefore, they are particularly suitable for Mobile Satellite Systems (MSSs). This paper compares the performance of several DCA solutions that are based on the evaluation of a cost function in terms of both quality of service parameters (i.e., blocking probabilities) and signaling load to be supported by the system. Both GEostationary Orbit (GEO) and Low Earth Orbit (LEO) MSSs have been considered. A particularly interesting DCA solution is proposed that tries to serve a new call attempt in a cell where no channel is available by means of a channel reconfiguration in an interfering cell. Handover requests that do not attain immediately service can be queued for a maximum time in order to enhance system performance.

Future mobile communication systems will be characterized by the interworking of several networks that will be integrated into a unique system. The satellite component and the terrestrial one will use as far as possible the same protocols. This work is concerned with Medium Access Control (MAC) protocols. In particular, Packet Reservation Multiple Access (PRMA) has been considered as a good candidate for terrestrial cellular systems, since it allows high multiplexing gains, dynamic PRMA carrier allocation to cells, easy management of integrated voice and data traffic and a near-transparent behaviour with respect to user mobility. The main aim of this preliminary work is to investigate the suitability of the PRMA protocol for application to Low Earth Orbit Mobile Satellite Systems (LEO-MSSs). Moreover, we have proposed a novel version of the PRMA protocol, named PRMA with Hindering States (PRMA-HS), that is particularly suitable for application in LEO systems. This new technique has shown very promising results in terms of both packet dropping probability and throughput.
