Abstract

''PROCESSO DE CONTROLAR A VARREDURA DE CANAIS DE RáDIO EM UM SISTEMA DE RADIOCOMUNICAçãO, E, ESTAçãO MóVEL'' Um processo e sistema habilitando uma estação móvel (MS1) operando no modo de espera e monitorando um canal de controle (CC1) em uma primeira CC4-CC6 sem perder mensagens, por exemplo mensagens de radiochamada, sobre o canal de controle (CC1) destinado para a estação móvel (MS1). Cada mensagem compreende pelo menos um bloco repetido de bits de informação. Mediante a recepção de uma mensagem no canal de controle monitorado (CC1), a estação móvel (MS1) determina dinamicamente um período de tempo durante o qual os blocos de informações portadores da mensagem não contém quaisquer novas informações destinadas para a estação móvel (MS1). Pelo menos parte do período de tempo é então usado para a varredura de outros canais de rádio (CC4-CC6).
