Dynamic resizing of a satellite link outroute or forward channel

1. A non-transient computer-readable storage medium having instructions embodied thereon, the instructions being executable by one or more processors to perform a method for resizing an outroute carrier from a gateway to a terminal population, the method comprising:

failing to maintain the outroute carrier in operation for the terminal population with an Uplink Power Control (ULPC) function in conjunction with an adaptive coding and modulation (ACM) function;

determining, at the gateway, that the failing was based on an insufficiency of the ULPC function in conjunction with the ACM function in conjunction with a fade;

downsizing, at the gateway based on the insufficiency, the outroute carrier by decreasing a symbol rate of the outroute carrier from the gateway for the terminal population while maintaining an aggregate carrier output power level to increase an outroute carrier margin by using more power for each symbol transmitted at the decreased symbol rate; and

upsizing, at the gateway, the outroute carrier by increasing a range of a frequency band of the outroute carrier in one or more steps while maintaining a center frequency of the frequency band, when the insufficiency expires or is reduced in scale,

wherein the determining further comprises determining that the insufficiency has expired and

wherein the resizing changes the symbol rate of the outroute carrier.

2. The method of claim 1 , further comprising selecting, at the gateway, a diversity gateway not subject to the fade; and when the diversity gateway is available, switching to the diversity gateway instead of the downsizing, wherein the fade of the outroute carrier is between a satellite and the gateway.

3. The method of claim 1 , wherein the downsizing decreases the range of the frequency band of the outroute carrier in one or more steps while maintaining the center frequency of the frequency band.

4. The method of claim 1 , wherein the downsizing halves the range of the frequency band of the outroute carrier while maintaining the center frequency of the frequency band.

5. The method of claim 1 , wherein a provisioning of the outroute carrier comprises multiple outroute carriers for a beam, and the determining and the downsizing are performed independently for each of the multiple outroute carriers.

6. The method of claim 1 , wherein the determining of the insufficiency is based on the ULPC function reaching a threshold power and the insufficiency expires or is reduced based on the ULPC function dropping below the threshold power.

7. The method of claim 1 , wherein the determining of the insufficiency is based on an average Modulation and Coding (MODCOD) value of at least a minimum of the terminal population reaching a threshold MODCOD value, and the insufficiency expires or is reduced based on the average MODCOD reaching a differential threshold MODCOD value.

8. The method of claim 1 , wherein the determining of the insufficiency is based on anticipating an outage due to predicted weather at a locus of the terminal population.

9. The method of claim 1 , further comprising transmitting a resize steps information, from the gateway to the terminal population, included in a system information or via an anchor outroute exempt from the downsizing.

10. The method of claim 1 , further comprising transmitting a resize steps information, from the gateway to the terminal population, via a neighboring beam adjacent to a beam comprising the outroute carrier, where the neighboring beam is transmitted from a second gateway other than the gateway.

11. The method of claim 1 , further comprising throttling, at the gateway, a streaming and bulk traffic to be conveyed by the outroute carrier to improve conveyance of an interactive traffic to be conveyed by the outroute carrier, and subsequently decreasing the throttling when the insufficiency expires or is reduced.

12. The method of claim 1 , further comprising proportionally adjusting minimum guaranteed bandwidths for each guaranteed bandwidth in megabits per second (Mbps) that has traffic to be conveyed by the outroute carrier, and subsequently restoring the guaranteed bandwidths when the insufficiency expires or is reduced.

13. The method of claim 1 , further comprising enabling a very robust MODCOD value for the outroute carrier prior to the downsizing; and disabling the very robust MODCOD value for the outroute carrier after the downsizing.

14. The method of claim 1 , further comprising enabling a very robust MODCOD value for the outroute carrier, when the downsizing of the outroute carrier has reached a threshold resize step information.

15. A satellite communication system to resize an outroute carrier from a gateway to a terminal population, the satellite communication system comprising:

an Uplink Power Control (ULPC) function in conjunction with an adaptive coding and modulation (ACM) function, at the gateway, to maintain the outroute carrier in operation for the terminal population and to determine a failing of the outroute based on an insufficiency of the ULPC function in conjunction with the ACM function in conjunction with a fade; and

a carrier size function, at the gateway based on the insufficiency, to downsize the outroute carrier for the terminal population by decreasing a symbol rate of the outroute carrier from the gateway while maintaining an aggregate carrier output power level to increase an outroute carrier margin by using more power for each symbol transmitted at the decreased symbol rate,

wherein the resize changes the symbol rate of the outroute carrier, and

the carrier size function upsizes the outroute carrier by increasing a range of a frequency band of the outroute carrier while maintaining a center frequency of the frequency band, when the insufficiency has expired or is reduced.

16. The satellite communication system of claim 15 , wherein the carrier size function halves the range of the frequency band of the outroute carrier while maintaining the center frequency of the frequency band.

17. The satellite communication system of claim 15 , wherein a provisioning of the outroute carrier comprises multiple outroute carriers for a beam, and the carrier size function determines a respective insufficiency for each of the multiple outroute carriers and independently downsizes the multiple outroute carriers based on the respective insufficiency.

18. The satellite communication system of claim 15 , wherein the insufficiency is based on both the ULPC function reaching a threshold power and an average Modulation and Coding (MODCOD) value of at least a minimum of the terminal population reaching a threshold MODCOD value.
