Solution Overview

Problem

Provisioning a network spectrum in large and complex networks is inefficient and time-consuming, particularly when recharacterizing RF channels in response to technological improvements or changing circumstances.

Innovation Solution

A remote provisioner computes an updated network profile to increase capacity, using intermediate bonding groups to reassigned devices without interrupting network service, allowing parallel reconfiguration of service groups with unique profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the network size is large and complex, then the network capacity can be increased, but the spectrum provisioning process becomes inefficient and time-consuming

Engineering Contradiction:
Improvenetwork capacityVSAvoidspectrum provisioning efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent segments the network into multiple service groups, each with its own unique network profile and RF channel configuration. This allows independent management and parallel processing of spectrum provisioning for different service groups, thereby improving overall efficiency while maintaining the ability to handle large network capacities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system computes updated network profiles in advance and determines optimal RF channel configurations before actual spectrum provisioning is needed. This preliminary computation enables faster execution of spectrum provisioning actions when required, resolving the contradiction between handling large networks and maintaining efficiency.

Inventive Principle:
Principle #10Preliminary action

2Quantity of substance

If the RF channel configuration is modified to improve network characteristics, then the network capacity increases, but the reconfiguration process is time-consuming

Engineering Contradiction:
Improvenetwork capacityVSAvoidreconfiguration time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The system computes updated network profiles and determines optimal RF channel configurations in advance, before actual reconfiguration is needed. This preliminary computation reduces the time required for actual reconfiguration operations while still achieving the desired network capacity improvements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables dynamic reconfiguration of RF channel configurations for service groups without requiring complete network shutdowns. By allowing incremental and parallel reconfiguration across different service groups, the system reduces overall reconfiguration time while maintaining network capacity improvements.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If the network profile is reconfigured to increase capacity, then the network characteristics improve, but service interruption occurs

Engineering Contradiction:
Improvenetwork capacityVSAvoidnetwork service continuity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The network is divided into multiple service groups that can be reconfigured independently. This segmentation allows the reconfiguration process to proceed in stages across different groups rather than requiring a complete network shutdown, thereby maintaining service continuity while still achieving capacity increases.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system maintains network service continuity during reconfiguration by keeping other service groups operational while one group undergoes reconfiguration. This continuous operation ensures that network capacity improvements are achieved without complete service interruption, maintaining reliability.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

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.
