Abstract

La présente invention concerne un procédé et un système de réduction de la consommation d'énergie, et un modem. Le procédé de réduction de la consommation d'énergie consiste : à recevoir, par un modem, un paquet de données; à analyser, par le modem, le paquet de données, et acquérir un numéro de port de destination contenu dans le paquet de données; à rechercher le numéro de port de destination dans une liste de numéros de port, la liste de numéros de port étant une liste qui est obtenue conformément à des informations de changement de numéro de port envoyées par un processeur d'application (AP) et contient un numéro de port actuellement utilisé par l'AP; et si le numéro de port de destination ne se trouve pas dans la liste de numéros de port, à mettre au rebut le paquet de données. La présente invention peut efficacement éviter une consommation d'énergie en pure perte due au fait qu'un AP traite un paquet de données indésirable, et peut en particulier éviter de réveiller un AP dans un état de veille pour traiter le paquet de données indésirable, ce qui permet d'atteindre le but de réduction de la consommation d'énergie.
