Abstract

Suporte a chamadas de emergência em uma rede local sem fio. Um dispositivo para identificar uma chamada de emergência em uma rede local sem fio, inclui um indicador para identificar uma chamada como uma chamada de emergência. Este indicador pode ser um flag de bit ou um elemento de informação. O elemento de informação pode incluir as informações de localização relativas à localização da estação que coloca a chamada de emergência. Esta informação pode ser utilizada para localizar quem realiza a chamada. A informação de localização pode ser transmitida desde a estação até um ponto de acesso de forma separada da ligação de emergência.
