Abstract

Patente de Invenção: <B>"SISTEMA DE COMUNICAçãO POR SATéLITE QUE PROVê DIVERSIDADE DE PORTA MúLTIPLA E UM CARREGAMENTO MELHORADO DE SATéLITE" <D>. Um método inclui as etapas de (a) estabelecimento de uma conexão de chamada entre uma rede de telecomunicações terrestres e um terminal de usuário via uma primeira porta e pelo menos um satélite, (b) enquanto a conexão de chamada estiver estabelecida, seleção de pelo menos um outro satélite, e (c) manutenção da conexão de chamada com a rede de telecomunicações terrestre via uma segunda porta, o pelo menos um outro satélite e a primeira porta. O pelo menos um outro satélite é selecionado, pelo menos em parte, com base na informação transmitida da segunda porta para a primeira porta através de uma ligação de comunicações entre portas, e pode ser com base nas indicações de qualidade de sinal determinadas no terminal de usuário, nas indicações de qualidade de sinal determinadas na(s) porta(s), ou em ganhos de trajetória calculados na(s) portas(s).
