Abstract

<B>MéTODO E APARELHO PARA O CONTORLE DA CAPACIDADE DE UM SISTEMA DE COMUNICAçãO<D> A capacidade de comunicação de enlace para frente de um sistema de comunicação, o qual está provendo, de uma estação de base para várias estações móveis, várias enlaces de comunicação para frente (123) correspondentes à pluralidade de estações móveis, é controlada pelo recebimento de uma regulagem de ganho (102), associada a pelo menos uma dos enlaces de comunicação para frente, comparando-se a regulagem de ganho com um limite de ganho (123), e ajustando-se uma primeira taxa de codificação de pelo menos uma dos enlaces de comunicação para frente para uma segunda taxa de codificação, com base na comparação. Um desvio de ganho (310) harmoniza o limite de ganho (123), para atualizar o limite de ganho (123), de acordo com uma última condição do sistema de comunicação. O desvio de ganho (310), ainda, é usado para determinar o bloqueio de uma chamada entrando no sistema de comunicação.
