Abstract: A distributed and scaleable Intelligent Service Network (ISN) architecture provides a global card mobility platform for enabling global card services. An ISN point of presence (POP) or node that comprises a scaleable matrix switching platform and voice call processing systems, is deployed to each country. These are referred to as Local Nodes. Extensive and generally expensive data and support systems are deployed in Regional Hubs, with multiple Local Nodes being connected to a single Regional Hub. This allows an inexpensive and minimized ISN node to be deployed in each country or shared by several countries. The other expensive components of a full-scale ISN are deployed and maintained by a large central company, and are shared by the multiple ISN Local Nodes in the region.
