Abstract: The invention provides exemplary systems and methods for provisioning network elements when providing local number portability services. In one exemplary method, local number portability subscription information which includes both ported global title translation data and location routing number data is entered into a single network element management system. Selective network elements which are in communication with the network element management system are then provisioned with the ported global translation data and the local routing number data based on logical network definitions stored in the network element management system.

Abstract: An expert system methodology for operating a computer system is disclosed to facilitate tuning, that is, resource balancing of the various resources comprising a large-scale software system. The computer system is adapted to store a knowledge base derived from experts who manually tune the large-scale system. The system also stores site-specific information and specifications on components configuring the large-scale system. Performance measurements collected from the large-scale system on a time consistent basis are merged, utilizing the knowledge base, with reference data derived from the site-specific information and the specifications. As a result of the merger, the status of the large-scale system is classified as to its operability. If the status is in a predefined class requiring tuning, the computer system is arranged to generate programming code which will effectuate the required changes in the resources to thereby reconfigure the large-scale system.
