Abstract

Systems, apparatuses, and methods are described for remotely reconfiguring the spectrum of a network based on a network profile associated with a service group. The service group may contain a group of modems that transmit and receive information over the spectrum of the network. The reconfigured spectrum may increase the network capacity of the network. The modems may continue to transmit and receive information while the reconfiguring is being implemented using intermediate bonding groups.

First claim

1 . A method of managing a network comprising:
identifying a spectrum associated with the network; determining a plurality of devices on the spectrum; computing a new channel configuration of the spectrum that increases network capacity on the spectrum; determining a portion of the spectrum that is unaffected by the new channel configuration; reassigning the plurality of devices to the portion of the spectrum that is unaffected by the new channel configuration using a plurality of intermediate bonding groups; determining that the plurality of devices have been moved to the portion of the spectrum that is unaffected by the new channel configuration using the intermediate bonding groups; implementing the new channel configuration on the spectrum; and moving the plurality of devices to a new portion of the spectrum based on the new channel configuration.

2 . The method of claim 1 , further comprising:
identifying a profile associated with the network, wherein the profile comprises information identifying the plurality of devices; and information identifying a current channel configuration of the spectrum, wherein the current channel configuration comprises a plurality of channels that are used by the plurality of devices to transmit and receiving information over the network.

3 . The method of claim 1 , further comprising:
determining an updated profile, wherein the updated profile comprises the new channel configuration configured to increase the network capacity of on the spectrum compared with the current channel configuration.

4 . The method of claim 2 , wherein the current channel configuration further comprises:
a plurality of single carrier quadrature amplitude modulation (SC-QAM) channels and an orthogonal frequency division multiplexing (OFDM) channel.

5 . The method of claim 2 , wherein the profile further comprises:
characteristics associated with the network, the plurality of devices, and the plurality of channels.

6 . The method of claim 2 , wherein the determining the portion of the spectrum that is
unaffected by the new channel configuration is based on differences between the current channel configuration and the new channel configuration.

7 . The method of claim 2 , wherein the plurality of devices may continue to transmit and receive information over the network using the intermediate bonding groups during the implementing.

8 . The method of claim 2 , wherein the plurality of intermediate bonding groups are further determined based on the unaffected channels and characteristics associated with the plurality of devices.

9 . The method of claim 5 , wherein the characteristics further comprise the current channel configuration, utilization data, policy constraints, and real-world constraints.

10 . The method of claim 8 , wherein the devices are moved to the plurality of intermediate bonding groups using dynamic bonding change messages.

11 . A method of remotely managing a network comprising:
identifying:
a plurality of devices associated with the network;
a plurality of channels associated with the network; and
a profile associated with the network, wherein the profile comprises information indicating a spectrum that the plurality of devices use to transmit and receive data on the spectrum;
generating, using a provisioner, an updated profile, wherein the updated profile comprises a new channel configuration of the spectrum that improves network capacity of the network;
determining a portion of the spectrum that is unaffected by the new channel configuration; temporarily reassigning the devices to the portion of the spectrum that is unaffected by the new channel configuration; reconfiguring the network, using a coordinator, based on the new channel configuration of the spectrum; and moving the devices to a new portion of the spectrum based on the new channel configuration.

12 . The method of claim 11 , wherein the profile comprises a current channel
configuration that is different from the new channel configuration.

13 . The method of claim 12 , wherein the reconfiguring further comprises:
determining a plurality of intermediate bonding groups based on differences between the current channel configuration and the new channel configuration.

14 . The method of claim 13 , wherein the devices may continue to transmit and receive data over the network using the intermediate bonding groups.

15 . The method of claim 14 , further comprising moving the devices from the intermediate bonding groups to best-fit bonding groups after the reconfiguring using dynamic bonding change messages.

16 . A method of remotely managing a spectrum associated with a network comprising:
computing a new spectrum configuration that increases capacity of the network using a mixed-integer linear programmer; routing a plurality of devices on the network to a portion of the spectrum that is unaffected by the new spectrum configuration; determining that the plurality devices have been reassigned to the portion of the spectrum that is unaffected by the new spectrum configuration; applying the new spectrum configuration while the plurality of devices continue to transmit and receive data using the portion of the spectrum that is unaffected by the new spectrum configuration; and rerouting the plurality of devices to a new portion of the spectrum based on the new spectrum configuration.

17 . The method of claim 16 , further comprising a profile that comprises:
the plurality of devices associated with the network; a plurality of channels associated with the network that are used by the plurality of network devices to transmit and receive data over the network; and a current spectrum configuration associated with the plurality of channels.

18 . The method of claim 17 , further comprising an updated profile that comprises the new spectrum configuration.

19 . The method of claim 18 , further comprising:
determining intermediate bonding groups based on characteristics associated with the plurality of devices and differences between the current spectrum configuration and the new spectrum configuration.

20 . The method of claim 19 , wherein the rerouting further comprises:
generating dynamic bonding change messages that direct the devices to move to the portion of the spectrum that is unaffected by the new spectrum configuration.
