Abstract

"SISTEMA DE REDE DE COMUNICAçãO CELULAR, E, PROCESSO PARA ESTABELECER UM LINK DE COMUNICAçãO DE DUAS VIAS ATRAVéS DE UM TRANSCEPTOR DE SATéLITE". Um sistemas de comunicação celular por satélite inclui um transceptor baseado no satélite para transceptar comunicações de duas vias originadas em um terminal de usuário. Como parte do estabelecimento da chamada, o controlador determina se o terminal de usuário deverá transmitir no uplink em um modo de faixa larga de operação ou em um modo de faixa estreita de operação. O controlador especifica, então, ao terminal de usuário, o modo de operação através do transceptor. Se o terminal de usuário transmite no uplink em um modo de faixa larga ou em um modo de faixa estreita depende de fatores incluindo o tipo de dispositivo, uso de canal e eficácia nos canais para o transceptor do satélite e do transceptor do satélite, e a qualidade de sinal dos sinais recebidos pelo transceptor.
