Abstract: PROBLEM TO BE SOLVED: To provide a new power management system that determines when and how long to switch a network interface of a wireless device into a low-power state without causing excessive delay in network traffic. SOLUTION: The power management system for use in the wireless device reduces the power consumption of the network interface module 201 of the wireless device by selectively putting the network interface module into a low-power state for an idle time. The length of the idle time is calculated such that the amount of delayed traffic data accumulated is expected to be less than or equal to a preselected threshold when the network interface module is put in the low-power state for the calculated idle time. The amount of delayed traffic data as a function of the idle time is modeled using average inter-arrival and service rates that are derived from traffic statistics data. COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: Un método para gestionar el consumo de potencia de un dispositivo informático inalámbrico (100) que tiene un módulo interface de red (201) para transmitir y recibir datos de comunicaciones por red inalámbrica, caracterizado porque el método incluye: analizar datos estadísticos de tráfico (204) para derivar parámetros de un modelo para predecir una cantidad de datos de tráfico retardados que se acumularán en función del tiempo cuando el módulo interface de red (201) se ponga en un estado de potencia baja en el que el módulo interface de red (201) deja de transmitir datos de comunicación por red; y calcular (401) un tiempo de inactividad deseado para el módulo interface de red (201) en base al modelo con los parámetros derivados, donde el modelo predice la puesta del módulo interface de red (201) en el estado de potencia baja durante el tiempo de inactividad deseado de manera que dé lugar a una cantidad de datos de tráfico retardados que es inferior o igual a un umbral preseleccionado.
