Abstract
"MéTODO E APARELHO PARA CONTROLAR A TRANSFERêNCIA ENTRE DIFERENTES SISTEMAS SEM FIO". Uma rede de comunicações sem fio (10) inclui um primeiro sistema de estação base (40) que realiza as comunicações sem fio de acordo com um primeiro protocolo (por exemplo, protocolo 1xEV-DO) e um segundo sistema de estação base (14) que realiza as comunicações sem fio de acordo com um segundo protocolo diferente (por exemplo, IS-2000). Uma conexão é fornecida entre os primeiro e segundo sistemas de estação base (40, 14) para permitir um procedimento de transferência iniciado por rede. Se um sistema de estação base fonte detectar que uma transferência de uma estação móvel para um sistema de estação base alvo é exigida, o sistema de estação base fonte permuta o envio de mensagens através da conexão com o sistema alvo da estação base para realizar a transferência. Em um exemplo, a transferência é uma comutação de célula rígida.
