  • Patent number: 8898201
    Abstract: Data migration between Home Location Registers (HLR) may be performed because another HLR platform better suits business needs due to its performance, or because the provider chooses to move to another make, model, or manufacturer, or may be the result of a combination of rationales. Data migration is ideally executed with minimal interruption of service to the customers of the telecommunications provider. The systems and methods disclosed herein provide an automated, repeatable manner of migrating data between HLR platforms using a flat source file created for each table from the original HLR platform being transferred. A series of scripts is created and run and if a step in the process or function of the system is not correctly executed, that source file and/or the series of scripts is edited or otherwise reviewed instead of re-downloading new data from the original HLR platform.
