Abstract

L'invention concerne une station mobile (1), notamment un appareil radio mobile, qui offre une possibilité de contrôle améliorée à son utilisateur. La station mobile (1) sert à échanger des informations avec des stations de base (5, 10, 15, 20, 25) qui couvrent, chacune, une zone géographique limitée (6, 11, 16, 21, 26). Une communication existant entre la station mobile (1) et une première station de base (5) peut être transformée par la station mobile (1) en une liaison entre la station mobile (1) et une autre station de base (10). La station mobile (1) signale la réception d'une information provenant de la première station de base (5) et concernant un transfert de liaison à venir vers une autre station de base (10), lorsque cette dernière (10) est affectée à un exploitant de réseau différent de celui de la première station de base (5).
