Abstract
Abstract A method of and system for routing switched termination telephone calls in accordance with international routing requirements and with consideration of available network capacity. A call is received at a switch of an international carrier. The switch sends a query identifying the first country as the country of origin for the call and the second country as the country of termination for the call to a service control point of the international carrier. The service control point determines from the query that the call is an international call and sends a request for a routing translation to a regulatory routing platform of the international carrier. The regulatory routing platform determines an optimal route for the call in accordance with international regulatory routing requirements.

Independent Claim
212 words
A method of routing telephone calls that originate in a first country and terminate in a second country in accordance with international regulatory routing requirements set forth in international agreements, which comprises the steps of: receiving a call at a first switch of a private network of an international carrier; sending a query from said first switch to a service control point of said international carrier, said query identifying at least said first country as the country of origin for said call and said second country as the country of termination for said call; determining in said service control point from said query that said call is an international call; sending a request for a routing translation from said service control point to a regulatory routing platform of said international carrier; determining in said regulatory routing platform an optimal route for the international call in accordance with said international regulatory routing requirements by determining the longest route on which the call can be transported on said international carrier's private network; returning from said regulatory routing platform to said service control point a routing translation for said optimal route; returning from said service control point to said first switch said routing translation; and, routing said international call in accordance with said optimal route.
Claim 10
Independent Claim
212 words
A method of routing telephone calls that originate in a first country and terminate in a second country in accordance with international regulatory routing requirements set forth in international agreements, which comprises the steps of: receiving a call at a first switch of a private network of an international carrier; sending a query from said first switch to a service control point of said international carrier, said query identifying at least said first country as the country of origin for said call and said second country as the country of termination for said call; determining in said service control point from said query that said call is an international call; sending a request for a routing translation from said service control point to a regulatory routing platform of said international carrier; determining in said regulatory routing platform an optimal route for the international call in accordance with said international regulatory routing requirements by determining the longest route on which the call can be transported on said international carrier's private network; returning from said regulatory routing platform to said service control point a routing translation for said optimal route; returning from said service control point to said first switch said routing translation; and, routing said international call in accordance with said optimal route.
