A system and method is provided for controlling the signalling between the subscriber of a mobile station and an external service node such as a message center. The control of the signalling is carried out by using unstructured supplementary service data (USSD) which is analyzed by a USSD handler of a home location register which invokes a transparent transfer to external service node (TTEN) application when the USSD does not correspond to a service defined within the home location register. The TTEN application establishes a dialog with the subscriber of the mobile station and the desired external service node by using USSD. This allows the subscriber of the mobile station to access all message services by sending one service code. Also, the operator is not busy while accessing the services and any incoming calls may be answered while accessing the services.
Système et procédé de gestion du trafic entre un abonné d'une station mobile et un noeud de service extérieur tel qu'un centre de messagerie. Ladite gestion est assurée par des "données non structurées de services supplémentaires" (USSD) qui sont analysées par un programme de traitement d'USSD d'une mémoire de position des utilisateurs permanents qui sollicite un "transfert transparent vers une application d'un noeud de service extérieur" (TTEN) lorsque les USSD ne correspondent pas à un service défini dans la mémoire de position des utilisateurs permanents. L'application TTEN établit un dialogue entre l'abonné de la station mobile et le noeud de service extérieur à l'aide de l'USSD, ce qui permet à l'abonné d'accéder à tous les services de messagerie par l'émission d'un code de service. Ainsi, l'opérateur n'est pas occupé pendant l'accès aux services et on peut répondre à toute communication entrante à ce moment.
