Executive Summary

Dear Sir/ Madam,

Türk Telekom Akademi has recently
held
its first workshop as the Centre of Excellence of the
International
Telecommunication Union (ITU
).
A great number of telecommunications sector
experts in these regions
Participated in

the NGN (Next Ge
neration Network) Workshop

held
in 21
-
23 October, 2010.

We hereby would like to give you information about Türk Telekom Ak
ademi which carries out
training and development activities on behalf of Türk Telekom Group.

As you may know, in the light of its deep information and experience that it has in the area of
developing information and communication technology Türk Telekom Ak
ademi has recently
signed a cooperation agreement with ITU to become an ITU Academy Centre of Excellence
(CoE). Under the scope of this co
-
operation agreement will serve as an ITU centre of
excellence and will be the central base of training and developmen
t for the area of human
capacity building regarding information communication technologies for the European, CIS,
Middle East and African regions.

Thus, Türk Telekom Akademi, with its title as the first regional “ITU Centre of Excellence” in
Turkey, will h
ave the mission to be a communication and cooperation channel of ITU in the
region and will carry out the required studies to establish a strong communication network
with other
centers

of excellence and to meet regional training and development
requirements
in co
-
operation with ITU.

20 telecommunication specialists coming from 12 different countries (Bosnia, Croatia,
Djibouti, Egypt, Jordan, Lebanon, Oman, Slovakia, Syria, Tajikistan, Tunisia, Turkey)
participated in our Workshop which was held u
nder the scope of the CoE agreement.

We received participation requests more than expected but nevertheless our quota was
restricted. Therefore we needed to make a selection among a number of applications
received, strict selection criteria were applied
and finally we needed to extend our quota. At
last, there were 23 participants who were eligible for our Workshop. However please kindly
note and closely follow that Türk Telekom Akademi as an ITU Centre of Excellence will be
holding at least two workshops

annually and we shall be glad to see the other applicants in
these future events who could not participate in the workshop because of our quota.

When it comes to profile of the participants, there were telecommunication specialists among
the participants
of the workshop employed in public and private telecommunication
corporations.


We made a very detailed search for this NGN training to find the most appropriate trainer on
this subject. And as a result of this search process we gladly decided on Mr Thoma
s
Magedanz to be the trainer of the workshop and invited him. We hereby especially wish to
thank him for accepting our invitation. Let us give you some brief info about him:

Thomas Magedanz(PhD) who is full professor in the Electrical Engineering and Com
puter
Sciences Faculty at the Technische Universität Berlin, Germany, leading the chair for Next
Generation Networks(NGN). In addition, he is director of the Next Generation Networking
infrastructure division of the FraunhoferInstitute FOKUS.

Thanks to our

fully competent instructor and high
-
level participants, we managed to hold a
very effective and efficient training in the subject of NGN. With the courage that their efforts
and goodwill gave us we will be able to organize even better workshops.

B.

Wor
kshop Overview


Information Technology has shown great improvement in the last 20 years with the
development of the internet and

wireless

communications

technologies

that find

a wide

range
of applications. With the development of internet,
accessing to information all around the
world by
using

high
-
speed
data

transmission

infrastructure

has become easier. Mutual
exchange of information

on the Internet

has affected

many aspects of

our lives;
for example,
international phone calls are no longe
r a luxury. On the other hand, with the spread of
wireless communications technologies, high
-
speed internet access has been provided to
mobile users.
These

applications are becoming more common with the
evolution of
end
-
user

devices such as ultra
-
portable
computers
,
advanced

mobile

phones

(mobile

phone
,
camera
,
radio
,
music

player
,
portable

memory
,
TV
,
Pocket PC
, etc.). End
-
users want to communicate
via

a single device which hosts all the functions of a computer, a television, a telephone.
Audio,

video and

data

transmission being performed via a single device increases the
attractiveness of

the next

generation

networks
.


In recent years
,
telecommunications

operators have realized that it is not economical to use
different networks for voice
,
data

and

video

communications. The need of using a single
network for voice, data and video communications because of the low OPEX and CAPEX
costs has triggered the transition to IP
-
based next
-
generation communication systems. In the
past years, many telecommunications o
perator
s

which operate in Europe and in the world
have been configured as a separate company by separating PSTN and GSM networks. As a
result of advances in the NGN technology and the understanding of advantages that NGN
will bring many telecommunication o
perators to decide to merge the PSTN and GSM
networks that
they previously set aside.

S
ome of them
have already
realized it. Examples on
this issue were mentioned in the workshop.


Standards of NGN technology which is thought to be used by all
telecommunications
operators in the future haven’t been fully and clearly defined. Organizations that determine
the standards lagged behind technological developments. In spite of this,

many

telecommunication

operators

began using

this

technology
.

Standard
s

will be determined

over
time
. In m
any

new

systems

it has
happened this

way.

Some systems and devices used during NGN transformation are only used to integrate the
current system to this technology (e.g. Trunk

Gateway
,
Signaling

Gateway

and

User

Access

Ga
teway)
. Some telecommunications operators are analyzing if it will be more economical
that throwing their existing confused access systems and using I
AD

(
Integrated
Access

Device
)
systems instead of i
t. That is why they are waiting and

watching operators
who is
engaged in the transformation of NGN.


It is defined that in many countries, policies that Competition and Regulation institutions
pursue is effective on the transformation decisions of NGN operators and it would be more
appropriate that the
information about this subject is given by experts because these issues
are political.


Türk Telekom is one of the leading telecommunications operators in the world which started
NGN transformation on time and which has been implementing it successfully. T
ürk Telekom
has been preparing for this transformation for a long time and has directed its investments
accordingly.

Workshop Content


NGN technology which is considered to be utilized by all Telecommunication operators in the
future and which has no exact and clear standards yet is defined as follows:


ITU
-
T defined NGN: A Next Generation Network (NGN) is a packet
-
based network able to
provide services including Telecommunication Services and able to make use of multiple
broadband, QoS
-
enabled transport technologies and in which service
-
related functions are
independent from underlying transport
-
related technologies. It offers unrestrict
ed access by
users to different service providers. It supports generalized mobility which will allow
consistent and ubiquitous provision of services to users.“


Why NGN? The NGN concept takes into consideration new realities in the
telecommunication indust
ry characterized by factors such as: the need to converge and
optimize the operating networks and the extraordinary expansion of digital traffic (i.e.
increasing demand for new multimedia services, increasing demand for mobility, etc.).


The IP
-
Multimedia
Subsystem (IMS) defines the functional architecture for a managed IP
-
based network. It aims to provide a means for carriers to create an open, standards
-
based
network that delivers integrated multimedia services to increase revenue, while also reducing
net
work CapEx and OpEx.


IMS was originally designed for third
-
generation mobile phones, but it has already been
extended to h
andle access from WiFi networks

and is continuing to be extended into an
access
-
independen
t platform for service delivery

including b
roadband fixed
-
line access. It
promises to provide seamless roaming between mobile, public WiFi and private networks for
a wide range of services and devices.

As indicated above, workshop has been focused on twelve main areas:

Türk Telekom NGN Rural Transformation and Round Table Discussion



Türk Telekom NGN Metropolitan Revolution

Türk Telekom performed Rural Transformation project as a preparation to NGN
transformation. With this project all rural switches which do not support ss7 signaling in the
field were replaced with MSAN’s those could be connected to the NGN systems with IP.


In this project different (6 types) of Rural Switches and millions of lines are replaced with
MSAN. These MSAN’s are connected to local Exchanges via V5.2.Transmission of MSAN
node in rural area accomplished by SDH via dark fiber (FTTC) MSAN support b
oth TDM
(v5.2) and IP (SIP,H248) interfaces free migration from V5.2 to H.248

As a result of the realization of this project, all PSTN subscribers in Turkey were brought to a
level to be able to utilize same features. MSAN (Multi Services Access Node) is
used for the
connection of the subscribers to the network. It is able to provide both voice and broadband
services from one access point in the network. It can be used for remote access unit in TDM
based PSTN networks. In NGN architecture it is used by dir
ectly connecting to the
Softswitches.


In Türk Telekom reasons for NGN Migration because of Old Equipments most of them
needed HW and SW upgrade for costumer demands for stronger communication, demands
for lower prices. In the existing infrastructure there

are high OPEX and CAPEX cost of
utilizing more than one Networks for voice and data transmission Clumsy & Cumbersome
Management System, Support Problem of the Vendors Low, Service Capability , Long
duration of New Service Launching. As well as these there

were technologic developments
mature NGN structure, t
rend toward All

IP infrastructure (IMS)
c
ompetitive
environment,
i

e
merging VoIP products in the market


Türk Telekom in TTNGN project Toll/Tandem layer exchanges are repl
aced with Soft
Switches and whole Turkey are controlled with these equipments. In migration period Local
Exchanges connect to SS via MGW. We can give next generation services via application
servers to entire network from one point. With the start of migra
tion V5 MSAN are directly
connect to SS via H.248 protocols. And after the migration whole local exchanges are
replaced with MSAN.



As a result, Türk Telekom decided to perform NGN transformation project by taking into
consideration the current and future

demands and requirements of customers and the
technological developments in the sector and started testing NGN systems.

Workshop Conclusions

In the workshop lasting for two days information was given on the point NGN reached today
and the future of NGN
. The difficulty of meeting operators’ customer requests and new
services with the present systems in telecommunication sector was explained. It was stated
that it isn’t economical to use distinct networks for voice, data and image transfer. It was also
i
ndicated that operation, maintenance and management of different Networks used for voice
and data communication constituted a high level of OPEX cost. It was revealed that same
operations could be done using NGN system with lower OPEX and CAPEX costs.

It
was stated that Next Generation Networks have package switching structure and supports
a wide range of service and application area, has broadband capacity with high quality of
service, can work with existing Networks with their open interfaces, supporting

Access of
users through various service providers and in addition to this preserving mobility and
convergence in both fixed and mobile Networks, supporting various Access Technologies,
and an integrated infrastructure available to serve voice, data and v
ideo services.

Why NGN;



It can use NGN systems because of low OPEX and CAPEX costs.



The NGN concept takes into consideration new realities in the telecommunication
industry characterized by factors such as: the need to converge and optimize the

operating

networks and the extraordinary expansion of digital traffic (i.e., increasing
demand for new multimedia services, increasing demand for mobility, etc.).



Next Generation Network (NGN) is a powerful platform to provide different services
like Voice, Video a
nd Data,



NGN provides a single multi
-
service network which encompasses all the elements of
existing telecommunication networks including public switched telephone network
(PSTN), wireless networks and data
n
etworks



NGN enhances the service delivery capabil
ities of networks.



NGN permits separation of transport, control and service & application layers,
providing greater flexibility to launch value added services.



The NGN provides the ways & means to provide bundled service offerings in the
areas of


Standard Voice Telephony;


Fax service;


E
-
mail & Internet;


E
-
Governance & E
-
Commerce Services;


Wideband / Broadband Access & Services;


IP TV, Video on demand; etc.



The migration to IP
-
based NGNs breaks the strong historical linkage between the
service

and the network, enabling the emergence of converged service providers.



Implications for regulation in support of competitive entry:


NGN introduces new forms of competition.


Does not necessarily eliminate traditional market power.


May enable the emerge
nce of new competitive bottlenecks



Many operators, especially incumbents, look to migrate to NGNs.


Enhance economies of scope and scale.


Accelerate time
-
to
-
market for new IP
-
based services.



NGN represents a marriage of PSTN and Internet.

As a result, bec
ause of the aforementioned reasons it was stated that all
t
elecommunication
operations will perform NGN transformation in the future and the future will IMS (
IP
Multimedia Subsystem), only one network will be used for voice, data and image.

Türk Telekom decided to perform NGN transformations project by taking into consideration
the technological developments in its area and current and future requests and requirements
of its customers and started testing NGN systems.

In this context, Türk Telekom Academi, under the patronage of ITU Centers of Excellence
Program has decided to take the initiative and organize a workshop on « Next Generation
Networks Workshop». Türk Telekom Academi has kindly volunteered to host the even
t in
Istanbul, during the period 21st October
-

22nd October 2010. Türk Telekom Academi has
collaborated closely in organizing and promoting the event.


In the ITU CoE NGN Workshop in Istanbul, current status and future of global NGN systems
was discussed

and the participants were informed about TTNGN project carried out by Türk
Telekom.
