Abstract

A method and system for identifying telemarketer communications directed to a subscriber of a call screening service is provided. A link monitoring system monitors all inbound and outbound calls of a carrier network collecting data such as calling and called telephone directory numbers, and a termination status for at least each inbound call to a calling number. The data is analyzed at a telemarketer detection module to determine calling patterns of calling numbers. If a calling pattern of a calling telephone number matches a profile of telemarketer communications, the calling number is stored in a database of telephone directory numbers associated with telemarketer communications. A call is received from a calling party directed to a subscriber of the call screening service. Then a determination is made as to whether a telephone directory number of the calling party is known. If the telephone number of the calling party is known, a determination is made as to whether the telephone number of the calling party matches a telephone number stored in the database of telephone numbers associated with telemarketer communications. If a match exists, the call is intercepted from reaching the subscriber of the call screening service.

Claims

1. A method for identifying telemarketer communications directed to a subscriber of a call screening service comprising:

receiving a call from a calling party directed to a subscriber of the call screening service;

determining whether a telephone directory number of the calling party is known, the determining performed by a service package application accessing a database;

if the telephone directory number of the calling party is known, determining whether the telephone directory number of the calling party matches one or more telephone directory numbers stored in a database of telephone directory numbers associated with telemarketer communications; and

if the telephone directory number of the calling party matches one or more of the telephone directory numbers stored in the database of telephone directory numbers associated with telemarketer communications, intercepting the call from reaching the subscriber of the call screening service;

wherein when the telephone directory number of the calling party is unknown, intercepting the call from reaching the subscriber of the call screening service and requesting that the calling party record a purpose for the call prior to routing the call to the subscriber.

2. The method of claim 1, wherein when the telephone directory number of the calling party does not match at least one of the telephone directory numbers stored in the database of telephone directory numbers associated with telemarketer communications, determining whether the telephone directory number of the calling party is private.

3. The method of claim 2, wherein when the telephone directory number of the calling party is not private, authorizing the call and routing the call to the subscriber.

4. The method of claim 3, wherein routing the call to the subscriber comprises:

notifying the subscriber of the calling party'"'"'s name; and

providing at least one option to the subscriber to handle the call, the at least one option comprising at least one of answering the call, ignoring the call, sending a message of unavailability, and sending a no call message.

5. The method of claim 2, wherein when the telephone directory number of the calling party is private, requesting the calling party to unblock a private status of the call.

6. The method of claim 1, prior to determining whether the telephone directory number of the calling party matches at least one of the telephone directory numbers stored in the database of telephone directory numbers associated with telemarketer communications further comprising:

monitoring inbound calls and outbound calls associated with a carrier network;

collecting a calling telephone directory number, a called telephone directory number, and a termination status for each of the inbound calls and the outbound calls monitored wherein the termination status comprises an indicator as to whether a call is answered;

analyzing the termination status of at least each inbound call to the calling telephone directory numbers to determine a calling pattern for each of the calling telephone directory numbers;

determining whether the calling pattern for any of the calling telephone directory numbers match a profile of telemarketer communications; and

when the calling pattern for any of the calling telephone directory numbers match the profile of telemarketer communications, storing those calling telephone directory numbers having a calling pattern that matches the profile in the database of telephone directory numbers associated with telemarketer communications.
