Abstract

"COMUNICAçãO SEM FIO DO PROTOCOLO DE INTERNET SEMPRE LIGADO". Segundo a presente invenção, a rede provedora de acessos (APN), que inclui um nó servidor de pacote de dados sempre ligado (PDSN), pode ser usada para comunicação através de um link de comunicação sem fio com uma estação móvel; a PDSN pode incluir um timer de inatividade, e pode ser usada para definir o timer de inatividade até um valor inicial do timer de inatividade e enviar uma estimativa do valor inicial para a estação móvel através do link de comunicação sem fio, onde a estimativa do valor inicial é uma função do valor inicial do timer de inatividade; a estação móvel pode incluir uma estimativa do timer de inatividade e pode ser usada para receber a estimativa do valor inicial e definir a estimativa do timer de inatividade para a estimativa do valor inicial; a estação móvel também pode ser usada para reiniciar a estimativa do timer de inatividade para a estimativa do valor inicial quando a estação móvel se comunica com a APN; um método de manutenção do link sempre ligado de comunicações sem fio entre uma estação móvel e uma rede provedora de acessos (APN) pode incluir os seguintes passos; estabelecimento de um link de comunicação sem fio entre a estação móvel e a APN; definição de um timer de inatividade na APN para um valor inicial; envio de uma estimativa do valor inicial a partir da APN para a estação móvel, que é uma função do valor inicial do timer de inatividade; definição de uma estimativa do timer de inatividade na estação móvel para a estimativa do valor inicial; monitoramento do link de comunicação sem fio entre a estação móvel e a APN para o tráfego de dados entre a estação móvel e a APN; se for detectado tráfego de dados, há o reinício da estimativa do timer de inatividade na estação móvel até a estimativa do valor inicial e o reinício do timer de inatividade na APN até o valor inicial do timer de inatividade.
