Abstract

"PROCESSO DE CONTROLE DE TRANSFERêNCIA DE UM CANAL EM UMA REDE DE RADIOCOMUNICAçãO CELULAR". A infra-estrutura comporta um núcleo de rede, controladores de rede de rádio ligados ao núcleo de rede e estações de base providas de interfaces de rádio e ligadas, cada uma, a um dos controladores. A informação codificada é transmitida sobre um primeiro atalho de comunicação em modo circuito entre o núcleo de rede e o terminal, passando por um primeiro controlador mestre, depois sobre um segundo atalho de comunicação em modo circuito entre o núcleo de rede e o terminal, passando por um segundo controlador mestre. O segundo atalho é estabelecido em um procedimento de transferência que compreende a transmissão de dados de regulagem do primeiro ao segundo controlador mestre e a supressão do primeiro atalho. Esses dados são representativos de um valor corrente de um número de seq³ência utilizado para cifrar a informação e incrementado em intervalos regulares, e de uma defasagem entre esse número de seq³ência e uma referência de tempo disponível no segundo controlador.
