<p>The present invention provides a passive monitoring method of redirecting roaming traffic associated with a subscriber. The method includes retrieving a first transaction ID at a TR probe, by passively monitoring a registration message intended for a home location information database. The method further includes retrieving a second transaction ID at the TR probe, by passively monitoring an update message originating from the home location information database. Further, the method includes sending an abort message by a TR unit, to the home location information database with the second transaction ID as a Destination Transaction ID (DTID) to restrict any further transactions with the home location information database using the second transaction ID. Finally, the method includes sending a registration response message by the TR unit, to a visited location information database with the first transaction ID as the DTID to restrict the subscriber from registering with the visited location information database, based on the subscriber's profile information stored in a database associated with the TR probe.</p> |
