Abstract :
To achieve really integrated systems allowing services and coverage provision from both terrestrial and satellite segments the identification of suitable intersegment handover (ISHO) procedure represents one of the most critical and crucial issues. The paper aims at analyzing some ISHO procedures and to evaluate their performance for different system configurations utilizing a dynamic constellation simulator in the time domain. On the basis of the above procedures, aiming at optimizing resources, a new procedure is proposed and analyzed. For each procedure execution delay and the delay complementary cumulative distribution have been evaluated for different constellation geometry. Finally, a performance comparison among the various procedures is be presented
