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 &ldquo;on-net,&rdquo; 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.

Methods for identifying service processing of telephone calls

A set of multidimensional capabilities allows service-related data to be exchanged among and operate with different hardware platforms and software programs. A trigger based on the call request is received at a switching platform. The trigger activates a service-specific object driver. The object driver is built by interacting with service objects. Once the object driver is built, the service objects are executed with call processing information based on the newly built object driver. During the entire process, network management functions are executed in a fault-tolerant fashion to ensure reliability.

Method and system for implementing intelligent telecommunication

In the case of an outbound international call originating from the U.S., an international communication system at a first switch receives, over a segment of the communication channel, the calling party's automatic number identification (ANI) and the dialed number (DN). The switch then sends a query to a processor having a previously stored customer processing records (CPRs). The database at the processor correlates the call information with the appropriate CPR; a service identity value is then inserted into a field which is unused for domestic calls. Call information including the service identity value is then transmitted to a second switch. When the service identity value indicates a service has been triggered, the transmitted call information is correlated with the appropriate index in a trigger table. The service-related values associated with the matched pseudo-country code are then inserted into the service-specific parameters. Finally, the service-specific values are delivered to the called party in the destination country using the service-specific parameters. A similar process is performed for an inbound international call originating from a foreign country and an international transit call.
