Abstract
(EN)
Methods and apparatus for optimizing power consumption in a wireless device by determining optimal signal release timing are disclosed. An accumulated data volume of one or more data calls received and transmitted in a device is measured during a first time period in which the device is in a connected state. After this period, the accumulated data volume is compared to a data volume threshold. Based on this comparison, a second time period may be set to either short or long time values, where the second time period is a time of the connected state of the device. After the second time period expires, SCRI signaling is sent to release the connected state of the device. By selectively setting the timing of the connected state of a device based on accumulated data volume during a first period, the timing for signaling of release from a connected state is optimized.

La présente invention concerne des procédés et un appareil d'optimisation de la consommation d'énergie dans un dispositif sans fil par détermination d'une temporisation de libération de signal optimal. Selon l'invention, un volume de données accumulées d'un ou de plusieurs appels de données reçus et transmis dans un dispositif est mesuré pendant une première période de temps durant laquelle le dispositif est dans un état connecté. Après cette période, le volume de données accumulées est comparé avec un seuil de volume de données. Sur la base de cette comparaison, une seconde période de temps peut être fixée à des valeurs de temps soit plus courtes soit plus longues, la seconde période de temps correspondant à une durée de l'état connecté du dispositif. À l'expiration de la seconde période de temps, une signalisation SCRI est envoyée pour libérer l'état connecté du dispositif. En fixant sélectivement la temporisation de l'état connecté d'un dispositif sur la base d'un volume de données accumulées pendant une première période, on optimise la temporisation de signalisation de libération d'un état connecté.
