Abstract

Patente de Invenção: <B>"SISTEMA DE COMUNICAçãO DE PORTA DISTRIBUìDA DE óRBITA BAIXA NA TERRA"<D>. Método para operação de um sistema de comunicação de um tipo que inclui um segmento de sistema de comunicação por satélite compreendido por pelo menos um satélite (10) que projeta uma pluralidade de feixes (1010) na superfície da terra, pelo menos uma porta de satélite terrestre (76) que é acoplada de forma bidirecional ao pelo menos um satélite e também ao sistema de comunicações terrestre, um segmento de comunicação terrestre compreendido por pelo menos uma estação de base de Laço Local Sem Fio (WLL) (1105), capaz de comunicações bidirecionais com uma pluralidade de terminais de usuário de WLL (1106) na região de serviço de WLL (1101). No sistema, um ou mais feixes de um ou mais satélites na superfície da Terra definem uma área de serviço regional na qual pelo menos uma região de serviço de WLL está localizada. O segmento terrestre ainda inclui uma porta virtual (1108) que é acoplada de forma bidirecional à estação de base de WLL e a pelo menos um satélite. A porta virtual pode transmitir pelo menos uma das mensagens de pager e de difusão para terminais de usuário de WLL.
