Abstract

"PROCEDIMENTO PARA ASSEGURAR CHAMADAS DE EMERGêNCIA EM UM AMBIENTE DE LAçO LOCAL SEM FIO". A invenção é relativa a um procedimento para assegurar chamadas de emergência em um ambiente de laço local sem fio, que é baseado em tecnologia empregada em um sistema de telefonia móvel, e que compreende uma central telefónica (a), um nó de acesso (2) conectado à central telefónica, um dispositivo terminal (3), e uma estação base (4) conecatada à central telefónica através do nó de acesso, e que serve para transmitir sinais de chamada entre o nó de acesso e o dispositivo terminal, no qual, a rede doméstica (5) do dispositivo terminal é definida por meio da estação base e do nó de acesso associado, no qual estações base (7) de outras redes são colocadas no ambiente de laço local, de modo que o dispositivo terminal receba sinais de informação a partir das estações base circundantes, e com base em ditos sinais de informação, determina a estação com a qual está se comunicando, e a chamada de emergência é estabelecida através de qualquer estação base compatível com o dispositivo terminal. Para assegurar o estabelecimento, com sucesso, de uma chamada de emergência quando a conexão entre o dispositivo terminal (3) e a central telefónica (1) de sua rede doméstica (5) é perdida, é gerada uma tonalidade de discagem por meio do dispositivo terminal, um número de emergência é discado através do dispositivo terminal identificado, e a função chamada de emergência do sistema de telefonia móvel é utilizada para o estabelecimento da chamada de emergência.
