Abstract

L'invention concerne un transfert interfréquence d'une connexion d'un équipement utilisateur, dans lequel la fréquence d'une connexion d'une liaison montante de l'équipement utilisateur vers une station de base reste la même et la fréquence d'une liaison descendante de la station de base vers l'équipement utilisateur varie d'une première fréquence de liaison descendante à une seconde fréquence de liaison descendante. Une demande pour le transfert est transmise de la station de base. L'invention concerne également les informations contenant la demande indiquant la seconde fréquence de liaison descendante et les informations indiquant que la fréquence de liaison montante reste la même. En réponse à la demande, la couche physique de la connexion d'une liaison montante est maintenue tout en changeant la fréquence de liaison descendante de la première fréquence de liaison descendante à la seconde fréquence de liaison descendante.
