Abstract

A spectrum management server generates and an electronic device uses a channel map solution for a predetermined travel route of the electronic device. The channel map solution includes at least one available channel for each of the plural geographic areas through which the planned travel route passes. At least two adjacent ones of the geographic areas have different channel availability.

Claims

1. A spectrum management server, comprising:

a communications interface over which communications with an electronic device are made, the electronic device having a need for spectrum access to carry out wireless communications; and

a processor that executes logical instructions to configure the spectrum management server to;

determine a planned travel route of the electronic device;

analyze the planned travel route against incumbent use of spectrum and identify available channels for use by the electronic device for an entire area of each of plural geographic areas through which the planned travel route passes, at least two adjacent ones of the geographic areas having different channel availability, and wherein each geographic area is a pixel from a grid of pixels, each pixel having a same area and shape and wherein each available channel is unoccupied by an incumbent user; and

communicate a channel map solution to the electronic device, the channel map solution including at least one available channel for each of the plural geographic areas; and

wherein a size of each pixel is based on a location-determining accuracy of the electronic device and selected to conform an area of each pixel to a valid channel map generation area for the electronic device on a per pixel basis, said conformance increasing an average number of available channels per pixel for the pixels through which the planned travel route passes relative to pixels larger than the selected size.

2. The spectrum management server of claim 1, wherein if a pixel overlaps two regions with different channel availability, the available channels for the pixel is a set intersection of the available channels from the two regions.

6. The spectrum management server of claim 1, wherein the server further selects one channel per geographic area to communicate to the electronic device.

7. The spectrum management server of claim 1, wherein, as part of the channel map solution communicated to the electronic device, the server includes plural available channels per geographic area.

8. The spectrum management server of claim 1, wherein the channel map solution comprises an expiration.

3. A spectrum management server, comprising:

a communications interface over which communications with an electronic device are made, the electronic device having a need for spectrum access to carry out wireless communications; and

a processor that executes logical instructions to configure the spectrum management server to;

determine a planned travel route of the electronic device;

analyze the planned travel route against incumbent use of spectrum and identify available channels for use by the electronic device for an entire area of each of plural geographic areas through which the planned travel route passes, at least two adjacent ones of the geographic areas having different channel availability, wherein each available channel is unoccupied by an incumbent user; and

communicate a channel map solution to the electronic device, the channel map solution including at least one available channel for each of the plural geographic areas; and

wherein each geographic area is a line segment along the planned travel route, each line segment having a width, the width selected to conform validity of the channel map solution to a location-determining accuracy of the electronic device.

4. The spectrum management server of claim 3, wherein one of the line segments ends and one of the line segments starts at each vertex of the planned travel route.

5. The spectrum management server of claim 3, wherein one of the line segments ends and one of the line segments starts at each intersection of the planned travel route and a border between two regions of different channel availability.

9. The spectrum management server of claim 3, wherein the planned travel route is approximated by and expressed as a series of line segments.

10. The spectrum management server of claim 3, wherein the server further selects one channel per geographic area to communicate to the electronic device.

11. The spectrum management server of claim 3, wherein, as part of the channel map solution communicated to the electronic device, the server includes plural available channels per geographic area.

12. The spectrum management server of claim 3, wherein the channel map solution comprises an expiration.
