Abstract

"MONITORAMENTO DE TEMPO DE RETRANSMISSõES DE PACOTES DURANTE TRANSFERêNCIA PROVISóRIA". A presente invenção refere-se a um método para a programação de retransmissões de dados, um método para uso em um esquema de retransmissão de dados, e a método para a atualização de um armazenador provisório de uma estação de base em sistema de comunicação móvel durante uma transferência provisória. A presente invenção se refere a uma estação de base que executa o método de controle e atualização, um terminal de comunicação para executar o método de programação e a um sistema de comunicação móvel compreendendo pelo menos um dentre uma estação de base e um terminal de comunicação. A fim de impedir a combinação errónea de pacotes de dados em um esquema de retransmissão de pacotes no receptor, a presente invenção provê um método que pode descarregar a região de armazenamento provisório associada a um pacote de dados recebido após a sua correta recepção. Além disso, é provido um método que monitora o tempo gasto desde o último armazenamento de um pacote de dados em uma região de armazenamento temporário de uma estação de base de modo a poder ativar o descarregamento da região de armazenamento temporário após a expiração de um período de tempo limite.
