Abstract

The present invention comprises methods for efficiently identifying international outbound calls, in the telecommunications network (TN) of the outgoing country, which should be screened as possibly requiring processing according to a Global Virtual Network Service (GVNS), as opposed to conventional international long distance (ILD) call processing. In particular, the present invention is directed to outbound international GVNS calls, known as “on-net,” which are from one GVNS location to another GVNS location of the same customer. International calls that are not Outbound International GVNS On-net calls, referred to as Other ILD calls, include at least three types: standard ILD, non-GVNS data and international GVNS off-net calls. Standard ILD, non-GVNS data calls and international GVNS off-net calls all have a routing number which comprises a country code (CC) followed by a national number (NN). In the present invention, all Outbound International GVNS On-net calls have a routing number which begins with a CC followed by a country code suffix (CC-suffix). Therefore, the presence of a CC-suffix after the CC in a call routing number indicates that the call should be screened as being, possibly, an Outbound International GVNS On-net call.

Claims

1. A method of screening a communication before service processing, comprising:

scanning a routing number of the communication for a first sequence of one or more digits; and

determining if a service identification, associated with the communication, is of a first service value, if the first sequence of one or more digits is of a first sequence value,

wherein prior to scanning the routing number for the first sequence of one or more digits, the routing number is scanned for a second sequence of one or more digits indicative of a country to receive the communication.

2. A method of screening a communication for service processing, comprising:

scanning a routing number of the communication for a first sequence of one or more digits;

processing the communication in accordance with a first service and in accordance with a first additional treatment, if it is determined that both the first sequence of one or more digits is of a first sequence value and a service identification, associated with the communication, is of a first service value; and

processing the communication in accordance with the first service in accordance with a second additional treatment, if it is determined that both the first sequence of one or more digits is of a second sequence value and the service identification is of a first service value.

3. A method according to claim 2, wherein the first sequence value comprises at lease one digit whose value is part of the national trunk prefix of a country to receive the communication.

4. A method according to claim 2, wherein the first sequence value comprises at least one digit whose value is part of the domestic application prefix of a country to receive the communication.

5. A method according to claim 2, wherein the first sequence value comprises a national destination code of a country to receive the communication which national destination code receives minimal communication traffic from a country sending the communication.

6. A method according to claim 2, wherein prior to scanning the routing number for the first sequence of one or more digits, the routing number is scanned for a second sequence of one or more digits indicative of a country to receive the communication.

7. An apparatus for screening a communication before service processing, comprising:

a scanner for analyzing a routing number of the communication for a first sequence of one or more digits;

a tester that determines if a service identification, associated with the communication, is of a first service value;

wherein prior to analyzing the routing number for the first sequence of one or more digits, the scanner analyzes the routing number for a second sequence of one or more digits indicative of a country to receive the communication; and

wherein the tester only determines if the service identification is of a first service value when the scanner detects the first sequence of one or more digits is of a first sequence value.
