Ensure upstream channel quality measurement stability in an upstream channel bonding system using T4 timeout multiplier
First Claim
1. A method, comprising:
- configuring a cable modem, that communicates using bonded channels, to periodically exchange ranging messages on the bonded channels, wherein a bonded channel ranging interval determines a period for the exchange;
monitoring a signal quality metric for a monitored channel of the bonded channels by periodically retrieving a quality measurement for the monitored channel, a period between each retrieval determined by a channel quality monitoring interval;
sending an invite ranging message to the cable modem before retrieval of the quality measurement for the monitored channel; and
retrieving the quality measurement for the monitored channel, wherein the signal quality metric for the monitored channel is based on the quality measurement;
wherein the configuring of the cable modem further comprises;
receiving a range request message; and
sending a range response message that includes a timeout multiplier for the bonded channels,wherein the bonded channel ranging interval is a product of a channel ranging interval for the cable modem and the timeout multiplier;
wherein the signal quality metric for the monitored channel is an average of the quality measurement retrieved from the cable modem and at least one other cable modem that each communicate using the monitored channel.

Abstract
A method and computing device for maintaining the stability of the upstream channel quality measurements in an upstream channel bonded system. The method configures a cable modem, that communicates using bonded channels, to periodically exchange ranging messages on the bonded channels, where a bonded channel ranging interval determines a period for the exchange. The method also monitors a signal quality metric for a monitored channel of the bonded channels by periodically retrieving a quality measurement for the monitored channel, a period between each retrieval determined by a channel quality monitoring interval. The method sends an invite ranging message to the cable modem before retrieval of the quality measurement for the monitored channel, and retrieves the quality measurement for the monitored channel. The method bases the signal quality metric for the monitored channel on the quality measurement.
