Abstract

são fornecidos um método, um equipamento e um produto de programa de computador para comunicação sem fio. o equipamento recebe um fluxo de pacotes de dados rtp através de um canal sem fio e aplica a descompressão de rohc para decodificar os pacotes. após uma falha da descompressão rohc, o equipamento identifica o número de sequência rtp (sn), o selo de data e hora de rtp (ts) e o tempo de recepção de pdcp (rt) de um pacote decodificado com sucesso anterior e o sn pdcp e rt pdcp dos pacotes com falha. utilizando a informação identificada, o equipamento estima o sn rtp e ts rtp de cada um dos pacotes com falha. o equipamento decodifica os pacotes usando as informações estimadas.
