A method of modem power conservation used in a data communications system having an infrastructure (101), and a modem (103), the modem registered with the infrastructure and adapted to provide data communications between a host terminal (105) and the infrastructure (101), the method including the steps of receiving, at the modem (103), a message, determining that the message is not deliverable to the host terminal (105), and responsive thereto entering, at the modem (103) a power conservation mode. An alternative method directed to the same purposes includes the steps of entering, at the modem (103), a power conservation mode after a first predetermined time has lapsed without message activity, then exiting the power conservation mode after a second predetermined time has lapsed, and finally registering with the infrastructure (101).

L'invention concerne une méthode pour économiser l'énergie consommée par un modem, dans un système de communication de données ayant une infrastructure (101) et un modem, le modem étant enregistré auprès de l'infrastructure et agencé pour assurer la communication des données entre un terminal serveur (105) et l'infrastructure (100). La méthode consiste à recevoir, au niveau du modem (103), un message, à déterminer si ce message ne peut être fourni au terminal serveur (105) et, conséquemment à mettre le modem (103) en mode "économie d'énergie". Une autre méthode ayant le même but consiste à mettre le modem (103) en mode "économie d'energie" après une première durée de temps prédéterminée sans transmission de message, puis à sortir du mode "économie d'énergie" après une seconde durée prédéterminée de temps et finalement à s'enregistrer auprès de l'infrastructure (101).
