Abstract

"MULTIPLEXAçãO DE DADOS DE TAXA VARIáVEL COM SERVIçOS DE DADOS". Técnicas para multiplexação de dados de taxa variável com serviços de dados em um canal compartilhado são descritas. Em um aspecto, os dados dos serviços de dados (320) são priorizados. Os dados de alta prioridade esperando pela transmissão podem resultar em um comando de diminuição sendo emitido para reduzir a taxa de dados de taxa variável (310), criando, assim, espaço para os dados de serviços de dados. Os dados de prioridade mais baixa dos serviços de dados podem esperar pelo próximo espaço disponível, sem reduzir a taxa de dados de taxa variável. Em outro aspecto, os dados de serviços de dados são categorizados em três ou mais níveis de prioridade. Os dados de alta prioridade podem tomar lugar dos dados de taxa variável. Dados de média prioridade podem resultar em um comando de diminuição reduzindo os dados de taxa variável. Os dados de baixa prioridade podem esperar pelo próximo espaço disponível, sem reduzir a taxa de dados de taxa variável. Vários outros aspectos são apresentados também. Esses aspectos têm o benefício de permitirem que dados de taxa variável e de serviços de dados sejam multiplexados em um canal compartilhado, enquanto equilibra a qualidade do sinal de dados de taxa variável e mantêm os serviços de dados quando os dados de taxa variável estão em uma taxa alta.
