METHOD AND APPARATUS FOR AUTOMATICALLY ENSURING CONSISTENCY AMONG MULTIPLE SPECTRUM DATABASES
First Claim
1. A method for verifying accuracy of geo-location databases, comprising:
- determining at least one geographical location to access;
accessing at least one geo-location database with said geographical location, to obtain database results;
comparing the obtained database results to a reference result; and
establishing an error condition for any comparisons that exceed an allowed pre-determined difference.

Abstract
An apparatus and method of providing accurate and consistent open spectrum results for secondary devices from different geo-location databases is presented. The results, which may be independently derived by each database, are independent of the database queried. The comparison permits some amount of latitude in spatial and temporal consistency between the databases as errors are only indicated if the temporal or spatial discrepancies are pervasive. In addition, large percentages of different locations showing discrepancies when compared also lead to corrective action being taken. Corrective actions that may be taken include forcing problematic databases to update, shunting requests by secondary devices in the problematic locations to acceptable databases or shutting down the problematic databases entirely.

15. A geo-location database system, comprising:
-
a geo-location database consistency checking mechanism; a plurality of geo-location databases, each providing database results based on a queried location; the geo-location database consistency checking mechanism transmitting location information to the plurality of geo-location databases, the geo-location database consistency checking mechanism determining spatial and temporal discrepancies between the geo-location database results; and the geo-location database consistency checking mechanism determining whether the spatial and temporal discrepancies exceed allowable error levels, and noting an error condition if said allowable levels are exceeded. - View Dependent Claims (16, 17, 18, 19, 20)
