Abstract

The present invention provides a method and system for implementing feature interactions between an AIN-based service and a switch-based call-forwarding service. In the present invention, the switch-based call-forwarding generates an Off-Hook Delay (OHD) trigger. In response, the SSP suspends call processing and sends the forward-to number to the SCP. Based upon the SCP'"'"'s determination of whether the forward-to number is for voicemail and other criteria such as time of day, day of the week, etc, the SCP determines whether the switch-based call-forward should be permitted or inhibited.

Claims

1. ) A method for routing calls in an Advanced Intelligent Network including the steps of:

a) Attempting a switch-based call-forward from a subscriber line in a Service Switching Point (SSP);

b) Detecting a trigger in the SSP based upon said step a);

c) Suspending call processing based upon said step b);

d) During said step c), determining whether the call forward should be permitted; and

e) Inhibiting or permitting the call-forward based upon the determination in said step d).

2. ) The method of claim 1 further including the step of sending a message to an SCP during said step c) based upon said step b).

3. ) The method of claim 2 wherein the message includes a forward-to number to which the call-forward attempt is made.

4. ) The method of claim 3 further including the steps of:

f) determining whether the forward-to number is a voicemail number; and

g) determining whether to forward the call in said step d) based upon said determination in said step f).

5. ) The method of claim 4 further including the step of preventing the call-forward in said step e) based upon the determination in said step f) that the forward-to number is a voicemail number.

6. ) The method of claim 5 further including the step of forwarding the call to more than one subscriber line prior to said step a).

7. ) The method of claim 1 further including the step of permitting the switch-based call forward in said step e).

8. ) The method of claim 1 further including the step of forwarding the call to voicemail in said step e).

9. ) The method of claim 1 wherein said trigger is an Off-Hook Delay trigger caused by the switch'"'"'s attempt to forward the call.

10. ) The method of claim 1 further including the step of forwarding the call to a second subscriber line.

11. ) An Advanced Intelligent Network Service Switching Point (SSP) including:

a plurality of specific digit strings including a first specific digit string;

a plurality of subscriber lines each assigned one of said plurality of specific digit strings;

a trigger associated with said first specific digit string and activated by a call to the first specific digit string at the SSP;

said SSP generating a request for a forwarding instruction based upon said trigger; and

said SSP receiving said forwarding instruction and forwarding the call based upon the forwarding instruction.
