A method of controlling setting-up a connection in a mobile communication system, comprising: storing, in at least one subscriber database, subscriber-oriented data for a subscriber registered in a home mobile radio network; entering the subscriber-oriented data in another subscriber database when the subscriber moves; and setting-up a connection for the subscriber with a mobile station using a mobile switching center in a visited mobile radio network, the mobile switching center being coupled to another subscriber database; wherein: a subscriber number profile, which contains valid call numbers for all registered subscribers, is stored in another subscriber database and, when the subscriber moves into the visited mobile radio network, the subscriber number profile is also stored in the subscriber database; and the mobile switching center compares the call numbers from the subscriber number profile with a called party address for a call which is initiated by the subscriber and, when a call number matches the called party address, a connection is set up to a service control point which translates the called party address into a new called party address and sends the new called party address to the mobile switching center to set-up a connection.
