1. A method of restoring a home location register after a home location register crash in a first home location register unit in a mobile radio system, said method comprising:

  • loading said first home location register with a previously saved backup copy; and

    updating, after loading said backup copy, records in said first home location register that are no longer valid with information from a second home location register unit that contains an up-to-date version of said first home location register, in which up-to-date version records that have changed after said backup copy was saved have been updated and tagged for later identification, thereby minimizing the update time of said first home location register by reducing the number of records that have to be updated in said first home location register to records that are no longer valid after loading said backup copy and correspond to said tagged records in said second home location register unit.
