Abstract
Patente de Invenção: MéTODO E EQUIPAMENTO PARA EFETUAR REPASSE DURO MóVEL ASSISTIDO ENTRE SISTEMA DE COMUNICAçãO. é descrito um método e um equipamento para efetuar o repasse duro entre diferentes sistemas de comunicação (S1, S2), ou o repasse duro entre diferentes freq³ências dentro de um mesmo sistema de comunicação CDMA. O propósito da presente invenção é o de reduzir a probabilidade de quedas de ligação durante o repasse duro entre sistemas. Caso uma tentativa de repasse duro não seja bem sucedida, a estação móvel (18) irá retornar ao sistema original (S1) com a informação que o sistema de comunicação da presente invenção utiliza para dar assistência ao desempenho de futuras tentativas de repasse duro. Alternativamente, sem que tenha sido feita uma tentativa de repasse duro, a estação móvel (18) monitora o sistema de destino (S2), a seguir retornando ao sistema original (S1) com informações usadas para dar assistência em subsequentes tentativas de repasse. As informações que retornam do monitoramento de um sismte a CDMA consistem de resultados de uma busca por um ou mais pilotos dados em deslocamento (offsets) em uma listagem específica provida à estação móvel (18) pela estação base (B1) a B5) ou um conjunto de deslocamentos (offsets) baseado em um algoritmo de busca predeterminado.
