Abstract

"SISTEMA DE COMUNICAçãO POR RáDIO". A razão de desconexão de chamadas de um terminal móvel é reduzida quando o terminal móvel durante comunicação está localizado longe de uma estação base e a perda de propagação de uma linha de rádio aumenta. No terminal móvel, quando um valor de potência de transmissão de uma unidade de controle de potência de transmissão se torna máximo, uma unidade de controle de dados de transmissão alimenta bits de controle de potência "0"e "1" lidos por uma unidade leitora de bit de controle de potência e um contador conta o bit de controle de potência "0". Se um valor contado do contador exceder um limite, a unidade de controle de dados de transmissão interrompe a transmissão de dados através de um canal suplementar acima e comuta transmissão de dados para transmissão de dados somente por um canal fundamental reverso.
