Method and system for efficient access to spectrum database

A.Y. Majid (Inventor)

Research output: Patent


Method for querying available communication channel information from a white space database (WSDB) for a mobile device in a wireless communication system. The mobile system e.g. comprises a processor and connected components capable to determine a predicted path (P) of the mobile device and perform a first White Space Database (WSDB) query (q), the query (q) being a multi-location query based on the predicted path (P). Furthermore a direction change from the predicted path (P) is determined based on one or more previous positions and a current position of the mobile device. If the determined direction change is larger than a direction change threshold value, an updated predicted path (P) is determined and a new white space database query (q) is sent based on the updated predicted path (P).
