Abstract

A method and computing device for transitioning into and out of partial service mode to make bandwidth available for other resources. A trigger value is set for a channel, where a first and second cable modem have registered to use the channel, and where the first cable modem is a bonded channel modem that utilizes a bonding group that includes the channel and at least one other channel. A modulation mode for the channel is monitored. The channel is transitioned from full service mode to partial service mode when the channel is in full service mode and monitoring detects that the modulation mode is less than or equal to the trigger value. The channel is transitioned from partial service mode to full service mode when the channel is in partial service mode and the modulation mode for the channel is greater than the trigger value.

Claims

1. A method, comprising:

setting a trigger value for a channel, wherein a first cable modem and a second cable modem have registered to use the channel, and wherein the first cable modem is a bonded channel modem that utilizes a bonding group that includes the channel and at least one other channel;

monitoring a modulation mode for the channel;

transitioning the channel from full service mode to partial service mode when the channel is in full service mode and the monitoring detects that the modulation mode is less than or equal to the trigger value; and

transitioning the channel from partial service mode to full service mode when the channel is in partial service mode and the modulation mode for the channel is greater than the trigger value.

2. The method of claim 1, wherein the setting of the trigger value further comprises:

receiving the trigger value for the channel; and

storing the trigger value for the channel.

3. The method of claim 1, wherein the trigger value is at least one of a modulation mode for the channel, a modulation mode for a spectrum group, and a priority for a modulation profile hopping rule.

4. The method of claim 1, wherein the transitioning of the channel from full service mode to partial service mode further comprises:

notifying the first cable modem that the channel is in partial service mode, thereby marking the channel as unusable by the first cable modem.

5. The method of claim 1, wherein the transitioning of the channel from partial service mode to full service mode further comprises:

notifying the first cable modem that the channel is in full service mode, thereby marking the channel as usable by the first cable modem.

6. The method of claim 1, wherein the first cable modem is a DOCSIS 3.0 modem, and wherein the second cable modem is at least one of a DOCSIS 1.X modem, and a DOCSIS 2.X modem.

7. A computing device, comprising:

a memory device resident in the computing device; and

a processor disposed in communication with the memory device, the processor configured to;

set a trigger value for a channel, wherein a first cable modem and a second cable modem have registered to use the channel, and wherein the first cable modem is a bonded channel modem that utilizes a bonding group that includes the channel and at least one other channel;

monitor a modulation mode for the channel;

transition the channel from full service mode to partial service mode when the channel is in full service mode and the monitoring detects that the modulation mode is less than or equal to the trigger value; and

transition the channel from partial service mode to full service mode when the channel is in partial service mode and the modulation mode for the channel is greater than the trigger value.

8. The computing device of claim 7, wherein to set the trigger value, the processor is further configured to:

receive the trigger value for the channel; and

store the trigger value for the channel.

9. The computing device of claim 7, wherein the trigger value is at least one of a modulation mode for the channel, a modulation mode for a spectrum group, and a priority for a modulation profile hopping rule.

10. The computing device of claim 7, wherein to transition the channel from full service mode to partial service mode, the processor is further configured to:

notify the first cable modem that the channel is in partial service mode, thereby marking the channel as unusable by the first cable modem.

11. The computing device of claim 7, wherein to transition the channel from partial service mode to full service mode, the processor is further configured to:

notify the first cable modem that the channel is in full service mode, thereby marking the channel as usable by the first cable modem.

12. The computing device of claim 7, wherein the first cable modem is a DOCSIS 3.0 modem, and wherein the second cable modem is at least one of a DOCSIS 1.X modem, and a DOCSIS 2.X modem.

13. A system, comprising:

a cable modem termination system (CMTS) that stores a trigger value for a channel, and that monitors a modulation mode for the channel;

a first cable modem registered to use the channel, wherein the first cable modem is a bonded channel modem that utilizes a bonding group that includes the channel and at least one other channel;

a second cable modem registered to use the channel,

wherein when the channel is in full service mode and the modulation mode for the channel is less than or equal to the trigger value, the CMTS transitions the channel from full service mode to partial service mode, and

wherein when the channel is in partial service mode and the modulation mode for the channel is greater than the trigger value, the CMTS transitions the channel from full service mode to partial service mode.

14. The system of claim 13, wherein the trigger value is at least one of a modulation mode for the channel, a modulation mode for a spectrum group, and a priority for a modulation profile hopping rule.

15. The system of claim 13, wherein to transition the channel from full service mode to partial service mode, the CMTS notifies the first cable modem that the channel is in partial service mode, thereby marking the channel as unusable by the first cable modem.

16. The system of claim 13, wherein to transition the channel from partial service mode to full service mode, the CMTS notifies the first cable modem that the channel is in full service mode, thereby marking the channel as usable by the first cable modem.

17. The system of claim 13, wherein the first cable modem is a DOCSIS 3.0 modem, and wherein the second cable modem is at least one of a DOCSIS 1.X modem, and a DOCSIS 2.X modem.

18. A non-transitory computer-readable medium, comprising computer-executable instructions that, when executed on a computing device, perform steps of:

setting a trigger value for a channel, wherein a first cable modem and a second cable modem have registered to use the channel, and wherein the first cable modem is a bonded channel modem that utilizes a bonding group that includes the channel and at least one other channel;

monitoring a modulation mode for the channel;

transitioning the channel from full service mode to partial service mode when the channel is in full service mode and the monitoring detects that the modulation mode is less than or equal to the trigger value; and

transitioning the channel from partial service mode to full service mode when the channel is in partial service mode and the modulation mode for the channel is greater than the trigger value.
