Abstract

"MéTODO DE CONTROLAR ACESSO ALEATóRIO EM UM SISTEMA DE COMUNICAçãO MóVEL E SISTEMA DE COMUNICAçãO MóVEL". Um método para controlar acesso aleatório é divulgado para um sistema de comunicação móvel para impedir que comunicações contínuas tais como comunicações de voz sejam interrompidas. Comunicações de acesso aleatório para uma estação móvel para reservar um canal de comunicações livre em uma estação base e comunicações contínuas tais como comunicações de voz entre as estações móvel e base são efetuadas em bandas de freq³ência ou aberturas de tempo diferentes respectivamente. A estação móvel reduz a taxa de alargamento e uma taxa de símbolo para comunicações de acesso aleatório.
