Abstract: A system and method for selectively routing telephone calls in an Advanced Intelligent Network, wherein an edge switch 102, comprising an AIN-equipped switching system, sends a query message to a service control point 108 and receives a response message containing call discrimination information about a telephone call, whereby the edge switch 102 determines whether to route the telephone call via a toll tandem office 100 for further processing. The system further includes a segmentation directory 140 which contains information determinative of which service control point 108 has the service logic to process the call.

Abstract: In processing a global title translation request, a segmentation directory performs a directory function based on information found in a services-related portion of a global title translation request, resulting in call parameters that allow the segmentation directory to determine the point code/subsystem number of a service processor needed to complete a call. Without altering a services-related portion of the global title translation request, a modified version of the global title translation request is sent to the service processor. Additionally, the segmentation directory can respond directly to exception and error conditions.

Abstract: An interexchange carrier (IXC) switch and an associated database route qualified calls dialed to local service provider (LSP) subscribers onto interconnecting facilitiies with local access settlement rates, thereby allowing a local rather than toll cost structure. The IXC switch and associated database operate with existing toll features including those features which translate a private dialed number into a public number. The IXC switch and associated database classify the call into a jurisdictional classification from a customer billing and feature application perspective, and from a routing perspective independent of the customer billing and feature application classification. The jurisdictional classification can include, example, local, toll, interLATA toll or intraLATA toll.
