Abstract

"método e aparelho para facilitar a transferência em rede de área local sem fio". é revelado um método e aparelho para facilitar a transferência de um ponto de acesso da rede (nap) que está disposto e construído para fornecer serviço a uma unidade de comunicação (cu) em um sistema de comunicação de salto de freqüência. as operações que são efetuadas são: fornecer serviço entre a cu e o nap em uma conexão, utilizando um primeiro padrão de salto de freqüência (fhp) ; determinar que a conexão é adequada para descontinuação com base no rssi ou na carga; enviar uma primeira mensagem que inclui uma id para o nap e u m cronograma para a cu aos naps vizinhos, a mensagem solicitando auxílio com o serviço no primeiro fhp; e receber uma segunda mensagem de um nap vizinho, disposta e construída para fornecer conexões às cus utilizando um segundo fhp, a segunda mensagem indicando que o auxílio pode ser fornecido pelo nap vizinho.
