Abstract

L'invention concerne un procédé d'appel, un système et un centre de commutation mobile (MSC) pour le transfert de service de réseau; elle concerne également le domaine des communications mobiles. Le procédé s'applique lorsqu'un terminal appelant appelle un terminal appelé, et ledit terminal appelant est transféré dans un second réseau à partir d'un premier réseau avec son numéro, le procédé consiste: en ce que le MSC du second réseau obtient dudit terminal appelant le numéro d'utilisateur individuel du second réseau du terminal appelant (11); ledit MSC du second réseau recherche le numéro d'utilisateur individuel du premier réseau, qui correspond au numéro d'utilisateur individuel du second réseau dudit terminal appelant, à partir d'une base de données de portabilité de numéros (NPDB) (12), et ledit MSC du second réseau envoie le numéro d'utilisateur individuel du premier réseau au MSC dudit terminal appelé (13); le service de portabilité de numéros est ainsi réalisé. L'invention peut concerne également le service de portabilité de numéros d'un système de téléphone personnel.
