Abstract

A system and method for restoring the original calling number in a call routed through an out-of-network enhanced service provider to a forwarding destination. The system comprises a service control point, a service switching point in communication with the service control point, and an enhanced service provider service node in communication with the service switching point, wherein the service node is located outside of a network while the remaining components reside within the network, and wherein the service switching point is provisioned with two triggers: an incoming trigger for calls to the service node and an outgoing trigger for calls from the service node. According to the method, the service control point, in response to the incoming trigger, removes and stores the private call information of a call exiting the network and, in response to the outgoing trigger, restores that private call information to the call once the call re-enters the network.

Claims

1. (canceled)

6. The method of claim 1, wherein the private communication information includes a calling number and a privacy indicator of the communication.

2. A method for preventing private communication information from exiting a network, comprising:

determining that a communication originally directed to an in-network called number is to be redirected to an out-of-network entity;

removing and storing the private communication information from the communication after determining that the communication is to be redirected to the out-of-network entity;

redirecting the communication to the out-of-network entity;

retrieving the stored private communication information when the communication re-enters the network from the out-of-network entity; and

restoring the retrieved stored private communication information to the communication.

3. The method of claim 2, wherein retrieving the stored private communication information includes locating the private communication information using an associated transaction identification.

4. The method of claim 2, wherein restoring the retrieved stored private communication information comprises inserting the retrieved stored private communication information into the communication.

5. The method of claim 2, wherein the out-of-network entity provides an enhanced service selected from a group comprising a call forwarding service, a call screen service, and an announcement service.

7. A method for preventing private communication information from exiting a network, comprising:

sending a first query to a control module residing in the network in response to receiving a communication that is to be redirected to an out-of-network entity, wherein the control module determines that the communication is to redirected to the out-of-network entity based on a called number, removes the private communication information from the communication, and stores the removed private communication information in response to the first query;

sending a second query to the control module when the communication re-enters the network from the out-of-network entity, wherein the control module retrieves the stored private communication information and restores the retrieved stored private communicator information to the communication in response to the second query.

8. The method of claim 7, wherein the out-of-network entity provides an enhanced service selected from a group comprising a call forwarding service, a call screen service, and an announcement service.

9. The method of claim 7, wherein the private communication information includes a calling number and a privacy indicator of the communication.
