(new Question)
Motivation
The emerging of NGN applications (IMS, IPTV services, broadband TV, fixed
mobile convergence) in the fields of telecommunications impacts the domain of
tests and instrumentations. Requirements for reactivity, interoperability and
scalability in terms of performance measurement are of another order of
magnitude than at the time being. ITU-T standardized test and instrumentations
techniques for a lot of transport techniques. Therefore the pressure impacts
more the reactivity, the interoperability and the scalability of the interfacing
of tests and measures with higher NGN constituent parts:
- NGN transport relies on heterogeneous transport techniques. The test and
measure technique and instrumentation for NGN requires a common framework to
harmonize functions and methods and to avoid duplication of works already
available in other SDOs.
- The maintenance of frame-based multi-operators transport requires tests
and measurement of the performance of the whole transport and of the
performance of each network crossed. Tests, measurement and results
collection must be adapted to multi-operator transport context.
- NGN functionalities such as terminals mobility, fixed-mobile convergence
are already deployed. Tests, measurement and results collection must be
adapted to terminal mobility.
- IPTV services connect millions of terminals. Tests, measurement and
results collection must be adapted to collect and organize massive
simultaneous measures.
- Measurement and results collection require a ground truth operational
interoperability to gain reactivity and scalability.
Question
Study items to be considered include, but are not limited to:
- What test, measurement and collection techniques for use on NGN
frame-based telecommunications systems and their constituent parts, and what
should be the specifications?
- What measurement and collection techniques to assess the performance of
NGN transmission involving terminal mobility need to be specified by ITU-T,
and what should be the specifications?
- What measurement and collection techniques to assess individual network
impact on the performance of a multi-operator transport need to be specified
by ITU-T, and what should be the specifications?
- What measurement and collection techniques to assess the performance of
massive simultaneous transport contexts need to be specified by ITU-T, and
what should be the specifications?
Tasks
Tasks include, but are not limited to:
- Specify a framework for NGN test and measure technique and
instrumentation for use on NGN telecommunications systems and their
constituent parts which is consistent with terminal mobility, massive
simultaneous measures and multi-operators transport;
- Specify the functions that allow results collection of measurement
involving terminal mobility situation, massive simultaneous measures
situation and multi-operators transport situation;
- Specify the transport control functions and management functions that
allow a test instrument to interact with NGN service control and to gain
access to a transport layer network;
