Abstract: In order to derive important parameters concerning
mobile subscriber MS with ongoing calls in Low Earth Orbit Mobile
Satellite Systems LEO MSSs, a positioning system had to be
integrated into MSS in order to localize mobile subscribers MSs and
track them during the connection. Such integration is regarded as a
complex implementation.
We propose in this paper a novel method based on advantages of
mobility model of Low Earth Orbit Mobile Satellite System LEO
MSS called Evaluation Parameters Method EPM which allows for
such systems the evaluation of different information concerning a
MS with a call in progress even if its location is unknown.

based on advantages of mobility model of Low Earth Orbit Mobile
Satellite System LEO MSS which allows the evaluation of instant of
subsequent handover of a MS even if its location is unknown. This
method is utilized to propose a Dynamic Channel Reservation DCRlike
scheme based on the DCR scheme previously proposed in
literature. Results presented show that DCR-like technique gives
different QoS performance than DCR. Indeed, an improve in
handover blocking probability and an increase in new call blocking
probability are observed for the DCR-like technique.
