Title (EN) WIRELESS TELEPHONE DEVICE AND METHOD FOR ITS CONTROL
(FR) TELEPHONE SANS FILS ET SON PROCEDE DE COMMANDE
Abstract:
(EN) A wireless telephone device and method for its control by which a base station which is most advantageous in view of position registration or line connection can be selected in consideration of the propagation loss by a terminal. A transmission output information signal representing the transmission output level of the base station is added to the control signal which is transmitted from the base station to a mobile device which corrects the RSSI level of the received wave in accordance with the transmission output information signal and selects a base station which is most advantageous in view of the position registration or the line connection. Thus, the propagation loss is taken into account in this selection.
(FR) L'invention porte sur un téléphone sans fil et sur son procédé de commande selon lequel une station de base se trouvant dans la meilleure situation relativement à la concordance des positions et au raccordement des lignes est sélectionnée par un terminal en fonction des pertes de propagation. Un signal informatif représentatif de la puissance d'émission de la station de base est ajouté au signal de commande émis par la station de base à destination d'un dispositif mobile qui corrige le RSSI (niveau de qualité du signal) de l'onde reçue en fonction du signal informant sur la puissance d'émission, et sélectionne la station de base se trouvant dans la meilleure situation relativement à la concordance des positions et au raccordement des lignes. On prend ainsi en considération les pertes de propagation pour la sélection.
