IMPLEMENTING AN INTELLIGENT NETWORK SERVICE FOR A PACKET-SWITCHED SERVICE USING A NODE INTERFACING A MOBILE COMMUNICATIONS NETWORK TO A PACKET DATA NETWORK

摘要

A module (310) interfaces a mobile communications network (4) to a packet data network (6A) and is capable of implementing an Intelligent Network Service for a packet-switched service for subscribers of the mobile communications network. A network interface module operative as such may obviate a need to configure a packet-switching module so that the packet-switching module can implement one or more Intelligent Network Services. An entry for a subscriber in a Subscriber Information Registry of a home mobile communications network is defined such that when a subscriber roams into a visited mobile communications network, the network interface module of the home mobile communications network is used to implement a session between the mobile terminal of the subscriber and a node of a packet data network.
