Abstract

This paper proposes a Time‐based Channel Reservation Algorithm (TCRA) suitable for managing handover and call
admission control procedures in future mobile satellite systems. These systems are characterized by a high rate of handover attempts
which can degrade significantly their performance. Therefore, we propose TCRA, a scheme which guarantees a null handover failure
probability by managing the channel through a reservation strategy in the cells to be crossed by the user. Based on the feature that
the satellite motion is predictable and deterministic, the scheme tries to maximize the channel utilization and enables the system to
handle the most important number of users. The performance of the TCRA scheme has been examined by simulations and compared to the
Guaranteed Handover (GH) scheme. The results show the behaviour of the algorithm and its performance. Copyright © 2003

Low earth orbit (LEO) satellite communication systems perform frequent intersatellite handovers for both fixed and mobile users. This paper proposes a satellite selection scheme for new/handover call requests when two or more satellites can be seen simultaneously. Each satellite in this scheme has a
