Communication satellite system with dynamic downlink resource allocation
First Claim
1. In a communication satellite system having a satellite in earth orbit with at least one uplink from a first region and plural downlinks to recipient stations in plural regions other than the first region, the downlinks to the plural regions utilizing plural downlink signal resources on the satellite, a dynamic downlink resource allocation method for allocating downlink resources between the regions, comprising:
- detecting a degraded downlink signal that is directed to at least one of the regions other than the first region; and
allocating additional downlink signal resources on the satellite to the degraded downlink signal and from selected other downlink signals.

Abstract
A communication satellite system dynamically allocates additional downlink resources on the satellite to selected downlink signals to compensate for signal degradation. A typical cause of such degradation is rain where the downlink station is located. Another cause of such degradation is increased communication traffic or bandwidth demand within a particular region.
