Abstract

L'invention porte sur un système de communication radio comprenant une unité (1) radio mobile et un nombre de stations de base (6, 8, 10 et 12). L'unité (1) mobile comprend, entre autre, un processeur (2) de commande, un processeur (3) de signaux numériques et un processeur (4) radio. L'unité (1) mobile reçoit un signal utile de sa station de desserte ou station de base (6) utile. Toutefois, lorsqu'un signal brouilleur provient d'une station de base (8) brouilleuse, l'unité mobile peut tenter d'effectuer un transfert vers l'une des deux stations (10, 12) de base voisines qui offrent des signaux (9, 11) apparentés, alternatifs, disponibles et appropriés. L'unité (1) mobile contrôle l'intensité du signal et du signal de porteuse utile par rapport au niveaux d'interférences du signal (5) utile provenant de la station (6) de base de desserte, ainsi que les intensités de signaux et la porteuse par rapport aux niveaux d'interférences des signaux (9, 11) des stations (10, 12) de base voisines. L'unité (1) mobile prend une décision quant à la réalisation d'un transfert et vers quelle station de base doit s'effectuer le transfert, sur la base de la porteuse par rapport aux niveaux d'interférences et aux intensités des signaux provenant des stations de base de desserte et voisines.
