Method of modifying the home location register (HLR) system database for digital wireless communication whenever the database contents of main memory are altered

摘要

The present invention provides a method for modifying the Home Location Register (HLR) system database for digital wireless mobile communication. The method modifies or revises the database of the HLR system that is used to manage mobile subscribers by maintaining all the wireless communication system subscribers' information such as electronic serial number, directory number, international mobile station identification, user profile and current location, etc. The method includes extracting subscriber information from the database which resides in a main memory device and is being used at the present time; migrating the extracted information to a new database; and saving the migrated information onto a disk. In addition, the present method automatically generates the structure and contents of the database to be modified, regardless of each database version and structure, and without requiring the modification and testing of the source code by an operator.
