First Claim
Patent Images
1. A communication system comprising:
- a radio to transmit and receive communication signals to and from a selected ground station; and
a management unit coupled to the radio and operable to dynamically set a threshold value for selecting another ground station based on a signal strength corresponding to the selected ground station;
wherein the management unit is operable to select another ground station when a signal strength corresponding to the other ground station exceeds the signal strength corresponding to the selected ground station by more than the threshold value set by the management unit.

Abstract
A communication system comprises a radio to transmit and receive communication signals to and from a selected ground station; and a management unit coupled to the radio and operable to dynamically set a threshold value for selecting another ground station based on a signal strength corresponding to the selected ground station. The management unit is operable to select another ground station when a signal strength corresponding to the other ground station exceeds the signal strength corresponding to the selected ground station by more than the threshold value set by the management unit.

8. A method of switching ground stations, the method comprising:
-
monitoring a signal strength corresponding to a currently selected ground station and a signal strength corresponding to one or more other ground stations; setting a threshold value based on the monitored signal strength corresponding to the currently selected ground station; calculating a difference between the monitored signal strength corresponding to the currently selected ground station and the monitored signal strength corresponding to each of the one or more other ground stations; and if the calculated difference corresponding to one of the one or more other ground stations exceeds the set threshold value, selecting that other ground station to replace the currently selected ground station. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A program product comprising a processor-readable medium on which program instructions are embodied, wherein the program instructions are operable, when executed by at least one programmable processor included in a management unit that selects a ground station with which to communicate, to cause the programmable processor to:
-
dynamically set a threshold based on a monitored signal strength corresponding to a currently selected ground station; calculate a difference between the monitored signal strength and a signal strength corresponding to each of one or more other ground stations; compare each of the calculated differences to the dynamically set threshold; and initiate procedures to switch communication from the currently selected ground station to the other ground station corresponding to the difference that exceeded the dynamically set threshold. - View Dependent Claims (16, 17, 18, 19, 20)
