CMTS Dynamic Upstream Channel Suspension for Cable Modem Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable networks face challenges in enhancing upstream transmission performance beyond current DOCSIS specifications, which are limited in efficiently managing and optimizing upstream channel resources, leading to suboptimal resource utilization and user experience.
Innovation Solution
An electronic device and method for a Cable Modem Termination System (CMTS) and Cable Modem (CM) that dynamically monitors upstream channel performance, instructs the CM to suspend or resume service flow transmission based on predefined thresholds, allowing for re-authorization of channels and switching between binding groups to optimize resource allocation and improve transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the upstream channel resources are managed using current DOCSIS specifications, then the basic transmission function is maintained, but the resource utilization efficiency is suboptimal and transmission performance cannot be sufficiently enhanced
Solution Approach 1:
The patent implements dynamic channel resource management by enabling the CMTS to monitor upstream channel performance in real-time and dynamically adjust channel allocations. The system can suspend or resume service flows based on predefined thresholds, allowing flexible adaptation to changing transmission conditions and optimizing resource utilization efficiency.
Solution Approach 2:
The patent changes operational parameters by introducing dynamic threshold-based control mechanisms. The CMTS monitors performance parameters (such as signal quality, error rates) and adjusts channel allocation parameters accordingly, suspending services when thresholds are violated and resuming when conditions improve, thereby enhancing transmission performance adaptability.
2Productivity
If upstream channel resources are allocated statically, then the system is simple to manage, but resource utilization efficiency is low and cannot adapt to performance degradation or improvement
Solution Approach 1:
The patent implements feedback mechanisms where the CMTS continuously monitors upstream channel performance and uses this information to adjust channel allocations. The system compares actual performance against predefined thresholds and automatically suspends or resumes service flows, creating a closed-loop control system that optimizes resource utilization without requiring complex manual intervention.
3Reliability
If service flow transmission continues on degraded upstream channels, then continuous service is maintained, but transmission quality deteriorates and resource waste occurs
Solution Approach 1:
The patent extracts or separates service flows from degraded upstream channels by implementing suspension mechanisms. When performance thresholds are violated, the system identifies and isolates the affected service flows, suspending them from the degraded channels while maintaining service continuity through alternative channels or waiting for condition improvement, thereby preventing resource waste on poor-quality transmission.

AI summary
The present disclosure relates to an electronic device, a method, and a storage medium for enhancing upstream transmission performance. In an embodiment, a cable modem termination system (CMTS) can be configured to acquire first transmission performance of an upstream channel of a cable modem (CM) based on receiving service flow transmission from the CM; and, in response to the first transmission performance of at least one upstream channel of the CM being lower than a first threshold, instruct the CM to stop or suspend the service flow transmission through the at least one upstream channel. In an embodiment, the CM can be configured to receive a first instruction from the CMTS during the transmission of the service flow through the upstream channel; and, in response to receiving the first instruction, stop or suspend the service flow transmission through the at least one upstream channel.
