System and method for preserving caller privacy |
摘要 |
A method and system are disclosed for preserving caller privacy in an advanced intelligent network comprising a service switching point and a second service switching point. The service switching point is adapted to suspend calls directed to a predefined number and forward signaling information associated with the call to the service control point. The service control point is adapted to alter the signaling information if a privacy restriction indicator in the signaling information is activated and to forward the altered signaling information to the service switching point. The method comprises the following steps: forwarding information identifying a calling party and any privacy restrictions on the calling party information from the service switching point to the service control point; and if the privacy restrictions indicate that the calling party information should not be delivered to the called party, altering the calling party information and forwarding the altered information to the service switching point.
