Abstract

"OPERAçõES DE VOCODER LIVRES DE TANDEM ENTRE SISTEMAS DE COMUNICAçãO NãO COMPATìVEIS". Operações de vocoder livres de tandem (TFO) entre sistemas de comunicação não compatíveis podem ser permitidas através de modificações de hardware em elementos de comunicação dentro de cada sistema. Em um aspecto, cada entidade de infra-estrutura no Sistema 1 compreende um Gerador de Quadro TFO intra-sistema (G1), um Extrator de Quadro-TFO intra-sistema (E1) e um Extrator de Quadro TFO (E2) do Sistema 2, que é não compatível com o Sistema 1. Cada entidade de infra-estrutura no Sistema 2 compreende um Gerador de Quadro TFO intra-sistema (G2), um Extrator de Quadro TFO intra-sistema (E2) e um Extrator de Quadro TFO (EI) do Sistema 1. Em uma modalidade, Geradores de Quadro TFO inter-sistema (G1, G2) também são fornecidos. Em outra modalidade, parâmetros inter-sistema e intra-sistema são utilizados para determinar o Conteúdo de Quadro TFO (820, 830), em resposta à determinação do tipo de fonte do quadro TFO sendo puncionado em um fluxo PCM (812).
