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. It is desirable to minimize the number of Other ILD calls which are subject to extra screening for being, possibly, an Outbound International GVNS On-net call. Selecting a CC-suffix which comprises the national trunk prefix (NTP) or domestic application prefix digit (DAPD) of the call receiving country insures that only a small percentage of Other ILD calls, such as are represented by mis-dialed standard ILD calls or mis-dialed non-GVNS data calls, contain the CC-suffix. If the NTP or DAPD cannot be used, then a national destination code (NDC) of the receiving country which receives minimal Other ILD call traffic is selected as the CC-suffix.
