20140089504 | CORRELATION OF MEDIA PLANE AND SIGNALING PLANE OF MEDIA SERVICES IN A PACKET-SWITCHED NETWORK - This invention relates to methods for correlating media streams and signaling sessions of services, for example, in a passive monitoring system of a packet-switched network. Furthermore, the invention also relates to an implementation of these methods in hardware and software, and provides a signaling plane probe, a media plane probe and a correlation unit. Moreover, a passive monitoring system comprising one or more of these hardware devices is provided. To correlate media streams and signaling sessions of services, the invention proposes to independently generate correlation keys in a media plane probe for monitored media streams and correlation keys for signaling sessions that are monitored by a signaling plane probe in a fashion that matching correlation keys are generated for a respective service. By identifying reports on the media streams and reports on the signaling session that contain matching correlation keys respectively, the media streams and the signaling streams are correlated in a correlation unit. | 03-27-2014 |
20130329595 | VOIP QUALITY MEASUREMENT ENHANCEMENTS USING THE INTERNET CONTROL MESSAGE PROTOCOL - This invention relates to a method for enhancing the quality information of a VoIP session by deducting information from received ICMP messages, in addition to quality information already collected from media streams and/or signaling streams of the same VoIP session. ICMP messages passing on the network link are monitored and correlated with an existing and ongoing VoIP session, i.e. media stream, already monitored by a media plane monitoring unit. A data record for the media stream(s) is expanded with information from the ICMP messages, thus giving a better and more complete quality feedback of the media stream reception at the two communication endpoints. | 12-12-2013 |
20130163446 | Correlation of Media Plane and Signaling Plane of Media Services in a Packet-Switched Network - This invention relates to methods for correlating at least one media path and a signaling session of a packet-switched network and to an implementation of these methods in hardware and software. To overcoming one or more of the limitations and challenges on the correlation of signaling plane and media plane of services, the invention defines a key, which can be used for correlation of media streams and signaling sessions. The invention is based on a signaling probe identifying new services and associated media paths of the media plane by detecting their corresponding signaling sessions and determining for each service a signaling session identifier. The signaling probe registers the signaling sessions and their media paths at a correlation unit using the signaling session identifiers as a key, which allows a media probe to query the correlation unit for respective signaling session identifiers that correspond to media paths detected in the media plane traffic. | 06-27-2013 |
