Abstract

This invention provides a telecommunications routing system and method that allows a switch (e.g., an intelligent peripheral) to control the routing to a special applications device, which results in savings of time, cost and capacity throughout the entire network. Control of the routing lies within the Service Switching Point (SSP) which reduces the need to requery a Service Control Point (SCP) in error situations. This invention incorporates into the SSP a remote IP routing table containing routing instructions for IPs. The SSP will know if an alternate route is possible, based on the error from the IP. The SSP will have a rudimentary intelligence about routing which allows it to reroute when necessary, without requerying back to the SCP. The remote IP routing table will also allow the SSP to route to a successive IP if the local IP, although operative, cannot process the request.
