TL;DR: The performance of the proposed DCA technique has been derived by computer simulations in terms of call blocking and handover failure probabilities and comparisons with the classical fixed channel allocation (FCA) technique and other dynamic allocation algorithms recently proposed in the literature have been carried out to validate the proposed technique.

TL;DR: A performance comparison with a classical fixed channel allocation has been carried out, and it has been shown that a higher traffic density, with respect to GEO systems, is manageable by means of LEO satellites.

TL;DR: A description and a performance evaluation of a medium access protocol which may be used in the UTRA system to provide constant-bit-rate (voice), variable bit- rate (video), and low priority data services is presented.

TL;DR: A user mobility model has been proposed and its statistical parameters have been derived and a new technique called last useful instant (LUI) which is based on the knowledge of the maximum time within which the handover procedure must be accomplished.

TL;DR: This paper proposes a strategy which eliminates forced call terminations due to handover failures, thus allowing the GH service, and an analytical model has been derived to calculate QoS parameters for a mixed population of GH and regular users.
