Introduction The present document forms one of a ser
17、ies of technical specifications and technical reports produced by TIPHON Working Group 5 addressing Quality of Service (QoS) in TIPHON Systems. ETSI ETSI TR 102 024-6 V4.1.1 (2003-09) 5 1 Scope The present document applies to IP networks that provide voice telephony in accordance with any of the TIP
18、HON Scenarios. The objective with the present document is to collect all results of various VoIP speech transmission quality tests and related information. The measurement descriptions are provided in order to explain the motivation for the measurement and to detail the test setup to the necessary e
19、xtent. In order to avoid duplication of work, the present document points to the appropriate documents where the measurement results have been published, originally. 2 References For the purposes of this Technical Report (TR) the following references apply: 1 ETSI TR 101 329-6 (V2.1.1): “Telecommuni
20、cations and Internet Protocol Harmonization Over Networks (TIPHON) Release 3; End-to-end Quality of Service in TIPHON systems; Part 6: Actual measurements of network and terminal characteristics and performance parameters in TIPHON networks and their influence on voice quality“. 2 ETSI TR 102 251: “
21、Speech Processing, Transmission and Quality Aspects (STQ); Anonymous Test Report from 2nd Speech Quality Test Event 2002“. 3 List of Measurement Results The first version of the present document, published as TR 101 329-6 1 in TIPHON Release 3 has covered measurement gained during the period 1999 to
22、 2001; the conclusions from which have contributed to the other documents of the TS/TR 101 329 series of ETSI deliverables. In addition the measurement results from the 2ndETSI speech quality test in 2002 are available in TR 102 251. The following list summarizes the measurement results available in
