Abstract

Un procédé de commande de communication selon la présente invention comprend : une étape lors de laquelle un appareil de station mobile, comportant un module d'identité d'abonné pouvant commuter, par des communications, des profils à utiliser pour communiquer avec des réseaux de communication mobiles, communique avec un premier réseau de communication mobile au moyen d'un premier profil correspondant au premier réseau de communication mobile ; une étape lors de laquelle, lorsque l'appareil de station mobile existe dans une zone de service du premier réseau de communication mobile, des premières informations de position indiquant la position géographique de l'appareil de station mobile sont transmises de l'appareil de station mobile au premier réseau de communication mobile ; et une étape lors de laquelle un appareil serveur gérant les profils fournit à l'appareil de station mobile un second profil, correspondant à un second réseau de communication mobile différent du premier réseau de communication mobile, par le premier réseau de communication mobile, en fonction des premières informations de position acquises par le premier réseau de communication mobile.
