Abstract

Patente de Invenção: <B>"SISTEMA DE RADIOCHAMADA MóVEL UNIVERSAL"<D>. Um sistema de comunicações (10) inclui pelo menos um satélite (105), pelo menos um portal terrestre (103) suscetível de ser bidirecionalmente acoplado com o pelo menos um satélite, pelo menos um sistema de radiochamada terrestre (109), e pelo menos uma unidade de usuário (106) suscetível de ser acoplada sem fio com o portal terrestre, através do pelo menos um satélite, ou com o sistema de radiochamada terrestre. O portal inclui um sistema de radiochamada (300) para receber uma mensagem de radiochamada para a unidade de usuário, para armazenar a mensagem de radiochamada recebida, e para seletivamente efetuar a entrega da mensagem de radiochamada recebida à unidade de usuário através do sistema por satélite ou através do sistema de radiochamada terrestre. O portal é bidirecionalmente acoplado com o sistema de radiochamada terrestre através do pelo menos um satélite, uma portal virtual (107), e uma unidade de interface de radiochamada (108). A unidade de interface de radiochamada inclui uma mensagem de radiochamada e sistema de recuperação (108a) para armazenar uma mensagem de radiochamada até ser determinado que a mensagem de radiochamada pode ser uma proveitosamente entregue ou não proveitosamente entregue à unidade de usuário via o sistema de radiochamada terrestre. As mensagens de radiochamada armazenadas podem ser posteriormente re-chamadas e entregues ao usuário.
