Establishment of connections between terminals for mobile subscribers of an interconnected network
First Claim
1. A method of establishing a connection between two terminals (SUT1, SIFt2) for mobile subscribers of an interconnected plurality of virtual private integrated services networks (VPN1, VPN2) and public networks (PTT1, PTT2), the virtual private networks (VPN1, VPN2) containing exchanges (NISDN1, NISDN2) with associated service control points (INSCP1, INSCP2) of an intelligent network, comprising the following steps:
- entering dialing information into a first terminal, said dialing information containing a network discriminating digit identifying the virtual private network of a desired subscriber;
setting up a data path to a service control point (INSCP1) of the virtual private network (VPN1) for transmitting the dialing information if the first terminal is connected to the virtual private network (VPN1), orsetting up a data path via an internetwork signaling transfer point to the service control point (INSCP1) of the virtual private network for transmitting the dialing information if the first terminal is not connected to the virtual private network (VPN1);
determining the current location of the desired subscriber by means of the service control point (INSCP1) using a visiting location register or a home location register;
determining a path to the desired subscriber with associated dialing information;
transmitting the determined dialing information over the data path to the first terminal (SUT1), andselecting the received dialing information by means of the first terminal.

Abstract
The establishment of a connection between two terminals for mobile subscribers of a private or a virtual private network, where the terminals may be connected anywhere in an interconnected network of a number of private or virtual private networks and public networks. According to the invention, intelligent network functions are assigned to private or virtually private networks, to control these complex tasks. By inserting dialing information that contains a network discriminating identification, a connection is established with a service control point in the private or virtually private network so that the functions of the intelligent network can be used to ascertain the dialing information.
