Abstract

Des modes de réalisation de la présente invention appartiennent au domaine des communications sans fil et concernent un procédé d'exécution d'un service d'itinérance mono-carte multi-numéro. En fournissant respectivement un numéro visité et un numéro domestique à un usager itinérant B, les deux numéros peuvent être considérés respectivement comme un numéro d'appelant d'un usager local itinérant A et un numéro d'appelant d'un usager domestique C quand un usager itinérant est dans un état d'itinérance. L'invention résout le problème lié, dans l'état de la technique, au fait que des messages IAM doivent occuper des ressources de canal téléphonique supplémentaires quand l'usager local itinérant A passe un appel, une connexion locale peut être établie d'après le numéro visité de l'utilisateur B et la boucle de la liaison de communication est résolue.
