Abstract
A system and method for selectively routing telephone calls in an Advanced Intelligent Network, wherein an edge switch 102, comprising an AIN-equipped switching system, sends a query message to a service control point 108 and receives a response message containing call discrimination information about a telephone call, whereby the edge switch 102 determines whether to route the telephone call via a toll tandem office 100 for further processing. The system further includes a segmentation directory 140 which contains information determinative of which service control point 108 has the service logic to process the call.
Claims12
A system for routing a telephone call in an Advanced Intelligent Network (AIN), the system comprising:
- a first control point 108 including AIN facilities, said first control point comprising a database containing routing information;
- a first switch 102 configured to receive a telephone call from a calling party, said first switch 102 including AIN facilities;
- a second switch 100;
- a first communication link 112 between the first switch 102 and the first control point 108, said first communication link 112 bypassing said second switch 100;
- a second communication link 105 between the second switch 100 and the control point 108;
- and
- a third communication link 104 between the first switch and the second switch;
- wherein in response to a telephone call received from a calling party, the first switch 102 makes a first query to the first control point 108 via the first communication link 112, said first query being routed to said first control point 108 without being routed via said second link and further wherein the telephone call is routed to the second switch 100 if a response to the first query indicates that the telephone call requires an interaction with the calling party.
In a system for routing a telephone call in an Advanced Intelligent Network (AIN), said system including;
- a control point 108 including AIN facilities, said control point comprising a database containing routing information;
- a first switch 102 including AIN facilities;
- a second switch 100;
- a first communication link 105 between the second switch 100 and the control point 108;
- and
- a second communication link 104 between the first switch and the second switch;
- the improvement comprising:
- a third communication link 112 between the first switch 102 and the first control point 108, said third communication link 112 fully bypassing said second switch, wherein in response to a telephone call received from a calling party, the first switch 102 makes a first query to the first control point 108 via the third communication link 112, said first query being routed to said control point 108 without being routed via said second switch 100;
- and
- wherein the second switch 100 is configured to complete the telephone call after requesting additional information from the calling party and receiving a response thereto, if the telephone call is determined to be of a first kind based on a first response message from the first control point 108;
- and
- the first switch 102 is configured to complete the telephone call without requesting additional information from the calling party, if the telephone call is determined to be of a second kind based on said first response message from the first control point 108.
