Claim:
A computer-implemented method comprising operational steps of: independent of call processing, determining whether or not systematically evaluating accuracy of data in a home location register will interfere with call processing or resources to be used for the call processing at the home location register; in response to determining that the systematically evaluating accuracy of data in the home location register will not interfere with the calling processing or resources used for the call processing: (a) identifying, from among a plurality of subscribers, a subscriber serviced by a visited location register; (b) identifying the visited location register servicing the identified subscriber; (c) forwarding a message to the identified visited location register to determine if there is a corresponding record for the identified subscriber; (d) determining, based on a reply to the forwarded message or lack thereof, the accuracy of a home location register's record for the identified subscriber; and (e) recording information about the accuracy of the home location register's record for the identified subscriber.
