Title (EN) METHOD AND APPARATUS FOR POWER CONTROL IN A TELEPHONE SYSTEM
(FR) PROCEDE ET APPAREIL DE REGULATION DE PUISSANCE DANS UN SYSTEME TELEPHONIQUE
Abstract:
(EN) In apparatus and a method of transmitting messages in predetermined time slots within fixed length time frames, during a call a target power level of transmission is set by a second unit, the second unit is operative to measure the power level of a received message and to send a power level control signal to a first unit to adjust the power level of transmission during the call, the control signal being dependent upon the measured power level, and in which the power level of messages sent by the first unit at the start of a call is set dependent upon the power levels of messages sent by the first unit in previous successful calls to the second unit.
(FR) Dans un appareil et un procédé de transmission de messages sous forme de créneaux temporels prédéterminés dans des tranches de temps de longueur fixe, au cours d'un appel, le niveau de puissance de transmission est réglé par une seconde unité qui sert à mesurer le niveau de puissance d'un message reçu et à envoyer un signal de régulation du niveau de puissance à une première unité afin d'ajuster le niveau de puissance de la transmission au cours de l'appel, ce signal de régulation étant fonction du niveau de puissance mesuré. Le niveau de puissance des messages envoyés par la première unité au début d'un appel est réglé en fonction des niveaux de puissance des messages envoyés par la première unité au cours des appels aboutis précédents.
