Title (EN) DISTRIBUTED CONTROL ARCHITECTURE FOR MOBILE SYSTEMS WITH OVERLAPPING SERVICE COVERAGE REGIONS
(FR) ORGANISATION DE COMMANDE REPARTIE POUR SYSTEMES MOBILES AVEC ZONES DE COUVERTURE UTILE SUPERPOSEES
Abstract:
(EN) In a mobile satellite communication system wherein a satellite (410) generates a plurality of spot beams, and both mobile stations and fixed terrestrial stations within the spot beams receive and transmit information on traffic channels (402) and command channels (401), two terrestrial stations (450A, 450B) are assigned a single set of common control channels (401, 404, 406, 408) for overlapping spot beams.
(FR) Selon l'invention, dans un système de communication mobile par satellite dans lequel un satellite (410) génère une pluralité de faisceaux en pinceau, deux stations mobiles et des stations terrestres fixes à l'intérieur de ces faisceaux reçoivent et émettent des informations sur des voies de trafic (402) et des voies de signalisation (401), on attribue à deux stations terrestres (450A, 450B) un ensemble simple de voies de commande communs (401, 404, 406, 408) destiné à superposer les faisceaux en pinceau.
