Method for operating a geolocation database and a geolocation database system

A method for the operation of a geolocation database comprising a spatio-temporal spectrum map comprising of white space spectrum occupancy and/or white space spectrum underutilization data, wherein

• a) at least one white space spectrum sensor takes measurement data remote from the geolocation database,
• b) the measurement data are transmitted to the geolocation database,
• c) the spatio-temporal spectrum map and/or its parameters and/or decisions based on this spectrum map are modified in dependence of the measurement data received by the geolocation database,
• d) and for replies transmitted to at least one white space device of the geolocation database in response to the request of the at least one white space device to register as a secondary spectrum user for a given geographical position, geographical area and given method of spectrum usage, complementary to the method applied by the geolocation database in order to estimate the potential interference caused by the white space device to incumbent spectrum users, further comprising the steps of:
• e) detecting signal parameters of incumbent spectrum users by means of the at least one white space spectrum sensor,
• f) transmitting spectrum measurements to at least one context unit for evaluation, classification and augmentation of detected signals originating from at least one white space spectrum sensor,
• g) transmitting evaluated spectrum measurements from the at least one context unit to at least one knowledge unit for creating data about spatio-temporal spectrum utilization by recording, estimating, learning, or predicting spectrum measurements from a multitude of geographically distributed white space spectrum sensors, and
• h) incorporating evaluated spectrum measurement data about spatio-temporal spectrum utilization into the geolocation database by means of refining and/or recommending refinements of decision thresholds and/or model parameters used to create and/or modify a model based spatio-temporal spectrum map and/or its parameters, which are used by the geolocation database to estimate potential interference.
