Title
(EN) BATTERY POWER MANAGEMENT FOR A CELLULAR DEVICE
(FR) GESTION D'ÉNERGIE DE BATTERIE POUR UN DISPOSITIF CELLULAIRE
Abstract
(EN)
Techniques for operating cellular internet of things (IoT) devices under a public cellular carrier are disclosed. During an active connection, the cellular IoT device's radio-controlling application can collect radio metrics by tapping into the diagnostics interface of IoT device's cellular modem to collect data regarding accumulative signal strength, block/bit error rate, and/or round-trip latency for the session, etc. During the active connection, battery and environmental information as well as application-based information can be collected and sent to a remote computing device. In an example, the cellular IoT device can be given revised or refined values for use in timers, which may be used by the device to more efficiently use idle and/or power-save modes to reduce battery power consumption. Moreover, the use of the timers may be extended to devices distinct from the cellular modem, thereby increasing the utility of the timers and the functionality of the IoT device.

L'invention concerne des techniques d'exploitation de dispositifs cellulaires de l'Internet des objets (IdO) dans le cadre d'une porteuse cellulaire publique. Pendant une connexion active, l'application de commande radio du dispositif cellulaire de l'IdO peut collecter des mesures radio par tapotement dans l'interface de diagnostic du modem cellulaire du dispositif de l'IdO pour collecter des données concernant une intensité de signal cumulative, un taux d'erreur sur les blocs/bits, et/ou un temps d'attente aller-retour pour la session, etc. Pendant la connexion active, les informations de batterie et d'environnement ainsi que les informations basées sur une application peuvent être collectées et envoyées à un dispositif informatique à distance. Dans un exemple, le dispositif cellulaire de l'IdO peut se voir attribuer des valeurs révisées ou raffinées destinées à être utilisées dans des minuteries, qui peuvent être utilisées par le dispositif afin de profiter plus efficacement des modes de veille et/ou d'économie d'énergie pour réduire la consommation d'énergie de la batterie. De plus, l'utilisation des minuteries peut être étendue à des dispositifs distincts du modem cellulaire, ce qui permet d'augmenter l'utilité des minuteries et la fonctionnalité du dispositif de l'IdO.
