SELF-HEALING INTER-CARRIER NETWORK SWITCH

摘要

A vendor evaluator system enables real-time or near real-time efficiencies of an inter-carrier switch. At a nominal periodic rate (e.g., every fifteen minutes or less), the vendor evaluator system updates a performance map of vendor exchanges to which calls may be routed from the switch. Specifically, in real-time or in near real-time, an updated performance score is generated for each vendor exchange and/or for each NPA-NXX code that is connected to the switch based on a weighted average of post dial delay, average call hold time, and attempt-seizure ratio. The score is compared against performance thresholds to determine whether or not the respective exchange and/or code should be included in a pool of acceptably-performing, candidate vendor exchanges from which a particular exchange is selected to service a call. Such techniques prevent poorly performing vendors from servicing calls routed by the inter-carrier network switch in real time or near real-time.

主权项

1. A method for delivering calls based on vendor performance, the method comprising:
determining, for each vendor exchange of a plurality of vendor exchanges connected to a private packet network backbone exchange (PPNBE), a respective performance score based on post-dial delay, attempt-seizure ratio, and average call hold time of a set of calls routed by the PPNBE to the each vendor exchange during a time period occurring immediately prior to an initiation of an execution of the method; comparing each respective performance score to one or more thresholds, and determining whether or not the each respective performance score is acceptable based on the comparison; when the each respective performance score is determined to be acceptable, including the corresponding vendor exchange in a pool of candidate vendor exchanges from which a terminating or forwarding exchange to service a call is obtained; when the each respective performance score is determined to be unacceptable, excluding the corresponding vendor exchange from the pool of candidate vendor exchanges; and providing the pool of candidate vendor exchanges to the PPNBE for use in routing calls.
