Abstract

"GERAçãO DE CONFERêNCIA E DE ANúNCIO PARACHAMADAS VOIP E VOATM SEM FIO". Um sistema detelecomunicação encaminha quadros digitais específicos sem fiode um primeiro dispositivo de comunicação sem fio através de umarede orientada para dados, sem codificação de voz, paradistribuição de informação para um segundo dispositivo decomunicação enquanto implementa conferência de múltiplas partese funcionalidade geradora de tom/anúncio. Serviços de geraçãode tom e anúncio são providos enquanto o caminho de chamadaretém o formato de quadros digitais específicos sem fio entre oprimeiro dispositivo de comunicação sem fio e a porta determinação. Quando tons são gerados pelo primeiro dispositivo decomunicação sem fio, mensagens de sinalização são enviadasdiretamente para o codificador de voz da porta de terminação parainiciar a geração de tons DTMF de taxa normal na rede determinação. Quando tons e anúncios são enviados para o primeirodispositivo de comunicação sem fio, um servidor de fonte,trabalhando em conjunto com um servidor de recursos, gera umaversão codificada sem fio do tom ou anúncio. Essa versãocodificada sem fio é então enviada ao primeiro dispositivo decomunicação sem fio, onde uma versão audível do tom ouanúncio é produzida. Quando conferência de múltiplas partes éiniciada, a primeira chamada é estabelecida através decomunicação de quadros digitais específicos sem fio. A primeirachamada é colocada em espera enquanto a segunda chamada écompletada utilizando um formato de linha de fio digital (porexemplo, PCM) . Através de codificação de voz, a conexão daprimeira chamada é renegociada para combinar com o formato delinha de fio digital da segunda chamada. Para completar achamada de conferência, as duas chamadas são combinadas nocircuito de conferência como uma seq³ência de tráfego de linhade fio digital composta.
