The present invention proposes a solution for providing IMS services and in particular mid-call services to users having circuit-switched controlled terminals and being not adapted to provide IMS services to the users. In particular, it is proposed to introduce a new node type called Mobile Access Gateway Control Function (MAGCF). This new node combines the logical functionality of a cellular switching center and the logical functionality of packet-based logic. The invention discusses a concept of the MAGCF handling mid-calls, which comprises identification of the received mid-call request, generating in accordance to the identified mid-call a corresponding message, tracking the status of the performed mid-calls.
La présente invention concerne une solution pour la fourniture de services de sous-système multimédia IP et en particulier des services en cours d'appel à des utilisateurs possédant des terminaux à commande par commutation de circuit et non adaptés à fournir des services de sous-système multmédia IP aux utilisateurs. En particulier, l'invention concerne l'introduction d'un nouveau type de noeud désigné fonction de commande de passerelle d'accès mobil (MAGCF). Ce nouveau noeud combine la fonctionnalité logique d'un centre de commutation cellulaire et la fonctionnalité logique de logique à base de commutation par paquets. L'invention décrit un concept de la gestion d'appels en cours par la fonction MACGF, comprenant l'identification de la requête d'appel en cours, la génération selon le message d'appel en cours d'un message correspondant, le repérage du statut des appels en cours effectués.
