Measurement Method and Evaluation Model of Voice Quality on Electric IMS Network

doi:10.3969/j.issn.1006-2475.2017.03.009

Abstract

Abstract:

An electric IMS voice quality measuring method based on passive probe message analysis is proposed, which obtains the basic performance indicators such as time delay

of voice session through parsing RTP, RTCP, SIP packets. A voice quality evaluation model is put forward to help the network operation and maintenance department to monitor and

evaluate the quality of a large number of concurrent voice conversations on the backbone network. The developed prototype system verifies the feasibility of the scheme.

Key words: passive mode, IP Multimedia Subsystem, QoS of voice, deep packet parse, assessment
