Abstract

"MéTODO DE EFETUAR UMA OPERAçãO DE ECONOMIA DE ENERGIA EM UMA REDE DE áREA LOCAL SEM FIO (WLAN) E MéTODO DE RECUPERAR DADOS DE UM PONTO DE ACESSO POR UMA ESTAçãO MóVEL EM UMA REDE DE áREA LOCAL SEM FIO (WLAN)". Uma estação móvel estabelece uma programação pela qual dados são intercambiados com um ponto de acesso. A programação permite à estação móvel utilizar um modo de baixa energia (608) em ocasiões fora dos períodos de serviço programado. No entanto, a estação móvel poderá ocasionalmente precisar recuperar dados adicionais do ponto de acesso, ou transmitir dados adicionais para o ponto de acesso, e assim inicia um período de serviço não programado para fazê-lo (614).
