Abstract:
A privacy management system in an advanced intelligent network having a first service switching point in direct communication with a subscriber telephone having a subscriber number, a second service switching point in direct communication with a service node and a service control point in communication with the first and second service switching points, comprising:(a) a termination attempt trigger provisioned on the subscriber line at the first service switching point triggering a first query to the service control point whenever a call from a calling party number to the subscriber telephone reaches the first service switching point; and (b) a service package application on the service control point responding to the query by determining whether the calling party number is a public number, a private number or an unknown number, wherein, when the call is from a private number, the service package application routes the call to the service node with the subscriber number in a re-directing party field, the calling party number in a calling party field and a calling party presentation indicator redefining the calling party number as public, and then the service node obtains the calling party's permission to override the calling party's privacy, and dials a first string comprising a customized dialing plan code, the subscriber number and the calling party number, such that the customized dialing plan code triggers a second query from the second service switching point to the service control point, the service control point returns a response to the service node with the subscriber number in a called party field, the calling party number in the calling party field and the service node number in the charge party field, and the service node routes the call to the subscriber line.
