Patent

CA 2236349

The invention relates to a direct data access (DDA) from a digital mobile network to a data network in a centralized manner in a first mobile switching centre (MSC2). Another switching centre (MSC1) is arranged to route a mobile data call, addressed to the centralized DDA, to MSC2 as a digital call according to a bearer service (UDI) supported by the mobile network. The interworking functions of the routed data call are divided between the MSCs. MSC2 comprises a first interworking function (IWF2) that provides the adaptation functions required by the centralized DDA and the digital bearer service. MSC1 comprises a second interworking function (IWF1) providing the adaptation functions required by the radio connection and the digital bearer service.

Accès direct aux données (DDA), depuis un réseau mobile numérique, dans un réseau informatique, centralisé dans un premier centre de commutation mobile (MSC2). Un autre centre de commutation (MSC1) permet d'acheminer un appel informatique mobile, adressé au DDA centralisé, à MSC2 sous forme d'appel numérique, au moyen d'un service support (UDI) appuyé par le réseau mobile. Les fonctions d'interfonctionnement de l'appel informatique acheminé sont divisées entre les MSC. Le MSC2 comprend une première fonction d'interfonctionnement (IFW2) assurant les fonctions d'adaptation requises par le DDA centralisé et le service support numérique. Le MSC1 comprend une deuxième fonction d'interfonctionnement (IWF1) assurant les fonctions d'adaptation requises par la liaison radio et le service support numérique.
