Abstract

"MéTODO E EQUIPAMENTO PARA RECUPERAçãO DE CHAMADAS EM UM SISTEMA DE COMUNICAçãO SEM FIO". Um método e equipamento para recuperação de chamadas em um sistema de comunicação sem fio (10). Quando o link de comunicação entre uma estação móvel (38) e uma estação base (32) está com problemas, a estação móvel e a infra-estrutura pre-organiza potenciais estações base de auxílio (34). A estação base da célula fonte entra em contato com todas as vizinhas aptas para a recuperação como auxiliadoras potenciais. Cada estação base de auxílio é instruída a utilizar um canal padrão para transmissões de auxílio. A transmissão de auxílio é considerada uma operação de recuperação de chamada. A estação móvel estabelece um soft handoff com a estação base de auxílio, em que o link direto utiliza o canal padrão e um canal alternativo. Uma vez completado o handoff, a estação base de auxílio interrompe a utilização do canal padrão. Em uma modalidade, a estação base da célula fonte fornece à estação móvel, a lista das vizinhas aptas para a recuperação na forma de overhead, durante as transmissões e antes do desenvolvimento dos problemas no link de comunicação.
