Abstract
Monitoring voice quality passively using line echo cancellation data across a telecommunications network and reporting monitoring data to a central network management system. Network is monitored for potential voice quality issues for pro-active isolation of problems prior to customer complaints about the problems. Line echo cancellation related and non-related data for IP and other networks is gathered and correlated together to provide voice quality assessments of network performance.
Claims10
A method for intelligent network monitoring in a telecommunications network, comprising:
- generating line echo cancellation (LEC) data from a line echo canceller on said network;
- analyzing said line echo cancellation data using line echo cancellation rules for said network;
- correlating said line echo cancellation data with voice quality data from a plurality of network elements;
- and
- providing a voice quality assessment of said network.
A method of monitoring a voice over packet network, comprising:
- determining, with a fuzzy inference system, line echo cancellation performance of a plurality of network elements;
- generating fuzzy line echo cancellation (LEC) data assessments of said network elements;
- analyzing said fuzzy assessments using a set of LEC rules for said network;
- and
- analyzing said fuzzy assessments to determine an aspect of said LEC performance of said network.
