Abstract

A method and system directed for use in an Advanced Intelligent Network (AIN) for detecting and processing calls from a calling party to a subscribing called party wherein the display of calling party ID information has been inhibited. The Advanced Intelligent Network includes at least one Service Switching Point (SSP) in electrical communication with a Service Control Point (SCP) or Adjunct Processor (AP) via an appropriate signaling link and having corresponding service logic. The system and method are operative to detect an AIN termination attempt trigger at the SSP, suspend normal call processing, and generate an AIN termination attempt message at the SSP for receipt by the SCP/AP requesting further call processing instructions. If it is determined that calling party ID information has been inhibited, a response message is generated at the SCP/AP for receipt by the SSP instructing the SSP to intercept the call, play a selected terminating announcement or request the calling party to display its ID information so as to perform further call processing.

Claims

1. For use in an Advanced Intelligent Network (AIN) having at least one Service Switching Point (SSP) in electrical communication with a Service Control Point (SCP) or Adjunct Processor (AP) via an appropriate signalling link, said SCP/AP having corresponding service logic, a method for detecting and processing calls from a calling party to a subscribing called party wherein the display of calling party ID information is unavailable or has been inhibited, comprising:

detecting an AIN Termination Attempt trigger at said SSP when attempting to terminate a call from said calling party to said subscribing called party;

suspending normal call processing at said SSP upon detection of said AIN Termination Attempt trigger;

generating an AIN Termination Attempt message at said SSP for receipt by said SCP/AP, said AIN Termination Attempt message requesting further call processing instructions;

determining at said SCP/AP whether said calling party ID information has been inhibited; and

if said calling party ID information has been inhibited, generating a predetermined response message at said SCP/AP for receipt by said SSP instructing said SSP to intercept said call, play a selected terminating announcement or request said calling party to display its ID information and perform further call processing.

2. The method of claim 1, wherein said AIN Termination Attempt message includes a Generic Name parameter having a presentation field operable to indicate whether calling party ID information will be displayed or inhibited.

3. The method of claim 2, wherein the step of determining whether said calling party ID information has been inhibited is accomplished by said SCP/AP service logic via reference to said presentation field of said Generic Name parameter of said AIN Termination Attempt message.

4. The method of claim 1, wherein the step of requesting said calling party to display its ID information and perform further call processing, comprises:

generating a Send To Resource message at said SCP/AP for receipt by said SSP, said Send To Resource message indicating the resource type as "Play Announcement and Collect Digits";

detecting said caller'"'"'s ID information at said SSP; and

generating an Authorize Termination message at said SCP/AP for receipt by said SSP and presenting said call to said subscriber.

5. The method of claim 1, wherein the step of playing a selected terminating announcement is accomplished by activating an AIN Intelligent Peripheral.

6. For use in an Advanced Intelligent Network (AIN) having at least one Service Node (SN) having corresponding service logic, a method for detecting and processing calls from a calling party to a subscribing called party wherein the display of calling party ID information has been inhibited, comprising:

detecting an AIN Termination Attempt trigger at said SN when attempting to terminate a call to said subscribing called party;

suspending normal call processing at said SN upon detection of said AIN Termination Attempt trigger;

determining at said SN whether said calling party ID information has been inhibited; and

if said calling party ID information has been inhibited, intercepting said call, playing a selected terminating announcement or requesting said calling party to display its ID information and perform further call processing at said SN.

7. For use in an Advanced Intelligent Network (AIN), a system for detecting and processing calls from a calling party to a subscribing called party wherein the display of calling party ID information has been inhibited, comprising:

a Service Switching Point (SSP) in electrical communication with said subscribing called party and said calling party for suspending normal call processing and generating a corresponding AIN Termination Attempt message upon detection of an AIN Termination Attempt trigger;

a Service Control Point (SCP) or Adjunct Processor (AP) in electrical communication with said SSP for receiving said AIN Termination Attempt message, determining whether said calling party ID information has been inhibited and generating a response message at said SCP/AP for receipt by said SSP instructing said SSP to intercept said call, play a selected terminating announcement or request said calling party to display its ID information and perform further call processing.
