What is the issue?
What work should be done in ITU-T?
 How should this work be organized?
 What are the objectives for restructuring the
Study Groups (SGs)?
 How will SG structure stay relevant?

What work should be done in
ITU-T?


TSAG examined the work of all the SGs and work
for the future
Identified about 40 “Blocks” of work that should
be treated as indivisible units. For example:
 Block 3A: tariff & accounting principles
 Block 5A: EMI
 Block 13B: architecture, interworking and
multi-protocol networks except Ethernet

How should this work be
organized?

Related Blocks are being associated into
about 15-20 Functional Groupings. For
example:
 Performance FG = Block 12A (all of
SG12) + Block 13A (WP4/13)
 EMI = Block 5A (all of SG5)

What are the objectives for
restructuring the SGs
Efficiency, relevance, clear mandates
 Visibility to outside world
 Many different views and objectives have
been introduced by the membership
 See recent report on restructuring work in
TSAG TD/340 Rev.1

A ITU-T should have a strong presence
T
in certain areas
U  Critical areas for future work must include:
 Next Generation Network (NGN)
 Security
I
 Mobility
T
 “E-Everything”
 Network infrastructure: Optical Transport, IPU

based Networks, Network Management,
Signalling, Performance, EMC, Architecture,
Interoperability, etc.

What seems to be nearly agreed?

Continue the SG as is
 SG3 – Tariff and accounting principles
 SG5 – Electromagnetic compatibility
 SG6 – Outside plant

What seems to be nearly agreed?

Core work of a SG to continue, with
possible additions
 SG4 – Network management
 SG12 – End-to-end performance
 SG15 – Transmission systems
 SG16 – Multimedia

Trends in Functional Groupings
Consolidate Network Operations: combine
WP2/2 and Network Management (SG4)
 Consolidate Performance: combine WP4/13
and SG12
 Build an NGN SG: discussion continues on
what and how much to include
 Build a Security SG

BUT – to make it interesting
Two approaches: Change for change sake
vs. If it ain’t broke, don’t fix it
 Balance between: massive consolidation
into a few large Study Groups vs. Study
Groups based on specific topics and
expertise

Some issues to be resolved
Numbering, Naming, Addressing, Routing:
Block 2A (mostly the current WP1/2) –
where to place?
 Keep Cable Broadcast together (SG9),
make small modifications or split it up
completely?
 Signalling – a SG or part of another SG?
 Keep a Mobility SG (SSG) or merge with
other work?

Some issues to be resolved
What goes into the NGN Study Group?
 What goes into the Security Study Group?
 Numerous details of work allocation among
150+ study questions

Considerations


Some consolidation of work will help
 Avoid divergent solutions
 Share time of experts among study items
 Reduce need for liaisons
Too much consolidation of work will hurt
 Less time per study item during meeting
 Parallel meetings cannot be covered by experts
 External liaison relationships become less clear

Consequences...or
Why do we care?
Make ITU-T THE most attractive place to
do international standards
 Make best use of experts’ time and
resources
 Avoid duplication and overlap of work
 Lower costs to membership and to ITU
 A bad structure will slow down or stop
work; a good structure can speed up work

Maintaining Future Relevance
TSAG is responsible to review progress of
the work programme, the allocation of work
among ITU-T SGs and between ITU-T and
ITU-R
 WTSA Resolution 22 gives TSAG authority
to change study group structure between
WTSAs and to create groups with short lifetimes
