Title
(EN) POWER CONSUMPTION CONTROL METHOD AND APPARATUS FOR A COMMUNICATION SYSTEM SUBSCRIBER UNIT
(FR) PROCEDE ET APPAREIL POUR DIMINUER LA CONSOMMATION DE COURANT DANS UNE UNITE D'ABONNE D'UN SYSTEME DE TELECOMMUNICATION
Abstract
(EN)
A subscriber unit (10) of a time division multiple access (TDMA) radiotelephone system is reconfigured in each time slot to a power consumption tessellation in which circuit components (12, 13, 21, 29, 56, 57, 58) not needed for communication signal processing in that time slot are powered down. In order to minimize the extent of circuitry that must be provided to distribute power consumption control signals, techniques such as clock frequency control (26, 30, 70) or power down commands (31, 67, 68) are utilized to modify controlled circuit component power consumption without actually controlling power supply circuits. Programmable ring frequency logic (20) controls the frequency of a ringing signal generator (58), and a high frequency ring control signal (70) is switched on and off in the cadence of ringing operation. An expansion header is provided to enable serving plural subscriber loop circuits with the same radio equipment for reducing per line power consumption.
(FR)
Une unité d'abonné (10) d'un système radiotéléphonique à accès multiple à répartition dans le temps (TDMA) est reconfigurée dans chaque intervalle de temps en une mosaïque de consommation de courant dans laquelle on diminue l'alimentation en courant des composants du circuit (12, 13, 21, 29, 56, 57, 58) qui ne sont pas nécessaires au traitement du signal de communication dans cet intervalle de temps. Pour minimiser l'ampleur des circuits nécessaires à la répartition des signaux de commande de la consommation de courant, on peut utiliser des techniques telles que la commande par la fréquence d'horloge (26, 30, 70) ou les commandes par interruption (31, 67, 68), pour modifier la consommation en courant des composants du circuit commandé, sans en fait commander les circuits d'alimentation en courant. Une logique à fréquence d'appel programmable commande la fréquence d'un générateur (58) de signal d'appel et un signal (70) de commande d'appel haute fréquence est produit et interrompu à la cadence de l'opération d'appel. On prévoit également une canalisation d'expansion principale pour pouvoir desservir les circuits en boucle d'abonnés avec le même équipement radio, et diminuer la consommation de courant par ligne.
