Use of geolocation and centralized spectrum management database to enable seamless channel-based handover and geofencing

摘要

A system for channel handover includes a mobile radio device and a server storing polygon operating area information for a plurality of overlapping polygon operating areas for wireless communication. The mobile radio device receives the polygon operating area information, and determines the device location. Based on the polygon operating area information, the mobile radio device selects a first channel of operation corresponding to a channel that is available for use within a first polygon operating area. The travel of the mobile radio device is tracked to determine when the mobile radio device has exited the first polygon operating area and entered a second polygon operating area. When this occurs, the device selects a second channel of operation corresponding to a channel that is available for use within the second polygon operating area. Alternatively, the channel selection may be determined by the server and transmitted to the mobile radio device.
