Accounting rate reform
ITU-T
o
Transition from accounting rates to cost orientation
•
to develop general principles and guidelines for the
establishment of accounting rates;
•
to determine cost components to be included in the telephone
accounting rates;
•
to expedite work on developing appropriate costing
methodologies;
•
to establish a transition period to avoid drastic changes,
particularly for the developing countries.
o
Termination charge procedure, allows governments or operators to
establish a single charge for terminating traffic in their country,
provided the charge meets certain multilaterally agreed criteria.
Settlement rate procedure, allows governments or operators to
negotiate cost-orientated and asymmetric settlement rates, better
suited to the new market situation.
Commercial arrangement, between countries that have introduced
liberalization. Recognized operating agencies will agree bilaterally
on the remuneration procedure that is most appropriate to their
needs.

TMN related project includes standardization work covering
TMN architecture, methodology, common requirements,
communication protocols, TMN resource information modeling
for generic, switching, V5/VB5 access, transport network view
and service management.
TMN standards have to cope with changes in the industry
while also satisfying current needs.
TMN Recommendations will result from cooperation with
regional and national bodies and industry forums
The specification of information to be exchanged is the
essence of TMN.
Requirements need to be understandable to management
experts and not necessarily to the modeling experts.
SG 4 work plan addresses IP and to create a TMN framework
for the unified management of integrated hybrid circuitswitched (PSTN) and packet-based networks.
The study of TMN requires various expertise and TMN-related
Recommendations are being developed in various Study
Groups within ITU-T.

QoS viewpoints
ITU-T
There are four viewpoints of QoS that make the
definitions and frameworks meaningful and practical for
everyone – users, vendors, network operators, service
providers etc.
CUSTOMER
Customer’s
QoS
Requirements
QoS
Perceived
By Customer

27
QoS
ITU-T
o The relationship between service and
network reliability will be addressed
due to the critical need with the
rapid deployment of IP-based
network and services.
o SGs 2, 4, 11, 12, 13 & 16 must make
this work converge
12-13 December 2002
ITU-T Seminar – Madrid, December 2002
28
QoS overview
ITU-T
o QoS framework/definitions exist (E.800, G.1000),
application requirements are well known (G.1010),
assessment/monitoring methods well underway
o Different approaches to QoS taken by different ITU-T
study groups tend to be as follows: SG12 provides the
user application requirements; SG13 provides UNIUNI IP network QoS classes capable of supporting
most use applications; SG 16 provides a third-party
“agent” control and signaling of QoS using future
vertical protocols
o NI-NI QoS classes capable of supporting most user
applications exist for ATM (I.356) and IP (Y.1541),
although new signaling is needed for the IP case
o SG 16 has a futuristic QoS Architecture direction to
deliver QoS dynamically, over multiple networks

ITU-T
Global Information
Infrastructure
o Global Information Infrastructure – a set of 38
Projects to ensure:
• Global standards, which are needed because of the
globalization of business
• Enable users to manage the creation, storage,
delivery & use of information
• Technological convergence & interconnection of
telecommunications equipment with computers
• Satisfaction of the new demands on the
communications infrastructure by information
providers and users

Next Generation Networks
ITU-T
o The concept of Global Information Infrastructure (GII)
enables people to securely use a set of communication
services supporting an open multitude of applications
and embracing all modes of information, any time,
anywhere, and at an acceptable cost and quality
o The term Next Generation Network represent certain
technologies, on which the GII concept can be based
o The general principles for NGN can be found in various
Y-Series Recommendations. NGN’s are considered to be
part of the GII’s “federation of networks”
