Abstract

La présente invention concerne un procédé réalisé par un dispositif (100) de communications servant à communiquer dans un système de communications comportant un réseau (110) de communications de rattachement et une multiplicité de réseaux (120, 130) de communications visités, le dispositif étant abonné au réseau de communications de rattachement avec un identifiant d'abonné de rattachement. Un profil d'abonnement est conservé sur le dispositif, le profil d'abonnement comportant l'identifiant d'abonné de rattachement, des justificatifs d'accès et des données de trafic du réseau de communications de rattachement. Le procédé comporte les étapes consistant à recevoir (302), en provenance d'un nœud (140) de réseau, une multiplicité d'identifiants d'abonnés locaux, des identifiants individuels parmi la multiplicité d'identifiants d'abonnés locaux étant prévus pour une communication dans des réseaux individuels parmi la multiplicité de réseaux de communications visités et à déterminer (304) qu'il y a lieu de s'inscrire auprès d'un premier réseau (120) de communications visité parmi la multiplicité de réseaux de communications visités. Le procédé comporte en outre les étapes consistant à sélectionner (308) un premier identifiant d'abonné local parmi la multiplicité d'identifiants d'abonnés locaux stockés, ledit premier identifiant d'abonné local étant prévu pour une communication dans le premier réseau de communications visité, et à envoyer (310) une demande d'inscription comportant le premier identifiant d'abonné local sélectionné au premier réseau (120) de communications visité. Le procédé comporte en outre les étapes consistant à recevoir (312) une réponse d'inscription, et à envoyer (314) une demande de signalisation au premier réseau de communications visité déterminé, la demande de signalisation comportant le premier identifiant d'abonné local et des données de trafic du réseau (110) de communications de rattachement.
