Abstract
Patente de Invenção: <B>"SISTEMA DE COMUNICAçõES POR SATéLITE POSSUINDO DESIGNAçãO DE USUáRIO E DESIGNAçãO DE RECURSO DISTRIBUìDAS COM GATEWAYS TERRESTRES"<D>. Um sistema de comunicações por satélite (10) inclui pelo menos um satélite (12); um controlador do sistema (38); uma pluralidade de gateways (18); e pelo menos um terminal de usuário (13) operável para bidirecionalmente comunicar-se com pelo menos um dos gateways através do pelo menos um satélite. Os gateways individuais da pluralidade de gateways estão bidirecionalmente ligados a pelo menos um sistema de comunicações terrestre (4) e atuam para ligar o terminal de usuário com o sistema de comunicação terrestre através do pelo menos um satélite. De acordo com um aspecto desta invenção, os gateways individuais da pluralidade de gateways são operáveis para receber uma requisição de acesso a partir do terminal de usuário, através de pelo menos um satélite e são adicionalmente operáveis para notificar o terminal de usuário requisitante, através do pelo menos um satélite, que o terminal de usuário é um dos aceitos pelo gateway para estabelecer um link de comunicação e dos não-aceitos pelo gateway para estabelecer o link de comunicação. Um gateway que não aceita um terminal de usuário pode indicar para o terminal de usuário, baseado pelo menos em parte em uma localização predeterminada do terminal de usuário, uma identificação de um gateway para o qual o terminal de usuário deve solicitar para propósito de acesso ou de conexão. O sistema adicionalmente inclui uma rede de dados (39) que interconecta o controlador do sistema e a pluralidade de gateways. A rede de dados pode ser transportada e incorporada como uma rede com fios, como uma rede sem fios ou como uma combinação de uma rede com fios e uma rede sem fios.
