Abstract
To install a virtual private network (VN) within a given mobile-radio network (MRN), a facility is proposed which is connected to the base stations (BS) and controls the establishment and release of calls between mobile subscribers (MS . . . MSX) assigned to the coverage area of the base stations, and a data base (HLR) connected to the facility, which contains a subscriber data set (DS) for each of said mobile subscribers with a first logic data set (LDS) for registering them as subscribers of the mobile-radio network. Each of some of these mobile subscribers (MS , MS , MS ) has a second logic data set (LDS-VN) for registering them as subscribers of a virtual private network. In this way, in addition to the data set (LDS) allowing access to the mobile-radio network (MRN) as such, the invention adds to the subscriber data set in the existing data base (HLR) a further data set (LDS-VN), which enables a mobile subscriber to access a virtual private network (VPN). Essentially this only requires taking steps in the mobile-radio software area, whereby the installation of one or several virtual private networks can be very easily accomplished. The implementation of an intelligent network which is superimposed on the mobile-radio network can be omitted.
