Patent

CA 2644604

The disclosure is directed to a mobile communication device that may receive wireless broadcast signals from a number of different base stations or transmitters. The device alternates its operation between a low-power mode and a higher-power mode to conserve battery power. The length of time the device remains in the sleep mode is its sleep interval. The sleep interval is a function of two components. One component is set by the wireless broadcast network and the other component is set by the carrier that provisions the mobile communications device. When the device awakens from the sleep mode, it can check the status of any notification messages. If there are any updates, then it will process them. If there are no updates, then it will return to the low-power mode.

L'invention concerne un dispositif de communication mobile pouvant recevoir des signaux de diffusion sans fil provenant d'un certain nombre de stations de base ou d'émetteurs différents. Le dispositif alterne entre un mode à faible puissance et un mode à forte puissance afin de ménager l'énergie des accumulateurs. Le temps pendant lequel le dispositif reste en mode inactif est son intervalle d'inactivité. L'intervalle d'inactivité est fonction de deux éléments: un élément est établi par le réseau de diffusion sans fil, et l'autre élément par la porteuse utilisée par le dispositif de communication mobile. Lorsque le dispositif est activé à partir de son mode inactif, il peut vérifier l'état des messages de notification. Si des mises à jour ont été faites, le dispositif les traite. Si aucune mise à jour n'a été faite, il retourne en mode à faible puissance.
