Npa split management in intelligent network environment

Abstract

An NPA split management system and associated methods for receiving from a user descriptive instructions regarding an upcoming NPA split, and responsively updating components of the Intelligent Network to reflect corresponding changes in the NPA codes assigned to lines, subscribers, services, etc. A user interface operating in conjunction with a Service Management System allows the user to declare an NPA split and define its characteristics, including the old NPA code, the new NPA code, the central office codes to be “transferred” to the new NPA, and the dates of beginning and end of the permissive dialing period (PDP). The SMS contains indicia corresponding to SMS-managed databases, or tables, records, or fields thereof, which definitively specify whether the data contained therein is affected by an NPA split. The SMS determines which items require updating to the new NPA code, and on which components the affected databases or services reside. The SMS transmits to each affected Intelligent Network component instructions to update the affected databases (or other items) by replacing the old NPA code with the new NPA code. The Intelligent Network component executes the update instruction and installs a translation table entry. When transactions arrive during the PDP, the Intelligent Network component translates mentions of the old NPA to the new NPA before providing the requested service, as the updated database no longer has references to the old NPA.
