Abstract: A method and a system for the operation of a geolocation database comprising a spatiotemporal 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 measurements received by the geolocation database.

Abstract: The invention relates to a method for network discovery in a wireless communication network comprising communication devices sending announcement signals regularly with a period being equal to or exceeding a predefined minimum announcement interval, wherein a first communication device a) communicates with a second communication device during a data exchange phase on a first channel; b) freezes the communication with the second device by signalling a freezing message terminating the data exchange phase; c) scans for the announcement signal of third communication devices on a second channel in a scan phase, wherein the scan phase duration is shorter than the minimum announcement interval; d) unfreezes the communication with the second communication device by signalling an unfreezing message; and e) repeats steps a) through d).
