    Patent number: 6594659
    Abstract: A sorting method for use with a database having randomly hashed records stored therein. The records are sorted in accord with a predetermined parameter and the database exists on a storage medium. At least one stage of the method includes sorting the records in accord with a subgroup of the predetermined parameter and into record groups stored in the storage medium. Records are further sorted in later stages and may be read onto a second medium for sorting. The sorting method allows the amount of processor memory used for sorting to be limited, such that adverse effects on normal call processing are limited or nonexistent.
