‰ NGN related QoS, including voice and Multimedia
¾ It is one of the major topic on which TC STQ will work in the next
months (the first deliverables expected soon – September 2008)
¾ A work program has been elaborated (taking also into account the
results of the workshop on multimedia QoS)

Major activities/deliverables (since 2005) –TC STQ
‰ (Wideband) Speech terminals (in particular for VoIP)
¾ A strong effort has been done to produce all the deliverables in due
time. The results have been disseminated inside and outside ETSI. A
release 2 is ongoing Æ WI125
¾ EG 202 425 definition and implementation of a VoIP reference Point.
¾ A set of 4 ES for VoIP Terminals ( ES 202 737 to 740): for wideband
and narrow band speech; for handset, headset and hands-free
terminals. These documents have in particular been used as a basis
for the collaboration with TC DECT.
¾ MI117: inputs for the updates of EN 300 175-8 & EN 300176-2 (DECT
speech terminals). Very efficient and fruitful collaboration with TC
DECT.
‰ No Work items dedicated to bandwidth extension (above 8kHz),
by WI 97 covers speech and audio (without bandwidth limitation)

Major activities/deliverables (since 2005) –TC STQ
‰ Published Results of STFs
¾ EG 202 396 part1 (result of STF 273) and parts 2&3 (results of STF 294)
• A Methodology to record and playback environmental noise
• A speech data base in noisy environments
• A quality model for wideband speech (the adaptation for narrowband has been
developed outside the STF); ÆWI124
‰ Quality criteria and test methods
¾ Under WI 104 : QoS and network performance metrics and measurement
methods.
• Part 1 provides general concepts,
• Part 2, planned for September, defines the Transmission Quality indicator combining
Voice Quality metrics.
• Part 3 defines network performance metrics and measurement methods in IP
networks (taking into account, in particular, results from IETF and ITU-T).
¾ Specification and measurement of speech transmission quality. Under WI 105,
the EG 201 377 is updated in order to take into account the new available
quality models (developed mainly inn ITU-T SG12 –no duplication of work)
