A method of controlling allocation of available television white space (TVWS) channels comprises: requesting data of available television white space channels in a geographical tracking area by a television band device 10, 12, 13, 15 (e.g. Mode 1 or Mode 2 personal, portable devices); identifying available television white space channels and base stations 11,14 of at least one cell within the area, including use of television band device location positioning; and defining and allocating at least one available television white space channel for the device in response to the request. The coexistence of cellular secondary systems in the geological tracking area may be checked. Available overlapping white space channels may be determined based on geo-location (positional) accuracy and a cell neighbour list. The request for available white space channels can be evaluated by filtering using the cell neighbor list. Base station 11, 14 network resources may be configured using base station location, cell neighbour list and other, interfering network base stations in an overlapping TV white space channel. Channels may be selected using lowest signal power. Position may be determined based on GPS, evolved observed time difference of arrival, or by cell identity and timing advance. |
