How telecoms looked in the beginning
First telephone demonstrated in around 1875
First personal computers emerged in the early
1960s (Apple / IBM?)
Limited functionality, no network connection
First mobile phone appeared in 1973, was the
size of a house brick and could only do
analogue voice

World Class Standards
How telecoms looked yesterday
Home phones were made out of “bakelite” and
were used for voice only
Computers increased in processing power /
functionality and connected to the network via
a simple 64kb/s modem
Mobile phones shrank drastically, and could do
voice and limited data, (9.6kbps and SMS)

World Class Standards
How telecoms looks today
Home phones are frequently cordless (DECT),
with advance network functions (caller ID, call
waiting …)
Computers have greatly increased processing
power / multimedia functional and connect to
the Internet via xSDL/cable (up to 10Gbps)
Mobile phones have increased functions,
(MP3/Photo/PDA), and the networks
(UMTS/GPRS) support faster data rates

Ericsson buys Marconi: Ericsson is paying £1.2bn for the name and
most of the assets of Marconi (Oct 05)
eBay buys Skype: for $4.1 Billion (June 05)
Lucent and Alcatel: to merge and form a new communication solutions
provider (April 06)
Juniper and NEC: announce plans for joint FMC solutions (Nov 06)
Nokia Siemens Networks: a 50-50 joint venture that will cover both fixed
line and mobile networks (June 06)
Google acquire YouTube: for $1.65 Billion (Oct 06)
3Com bid for Huawei: assets in H3C (Nov 06)
Others in the pipe ??? Media buzz around Nortel, Cisco, Motorola,
Ericsson ???

Operators feel the squeeze
Market competition is increasing
Incumbents squeeze incumbents (internationally)
Mobile operators squeeze fixed operators (UMA)
Fixed operators fight back with Wi-Fi solutions
Mobile operators are squeezed by Wi-Fi / Wi-Max
New players (MVNOs, CLECs, Google, Skype), squeeze everyone
Core revenue (voice) is saturated and profit declining
Whilst voice revenue stagnates, Data revenue increases
Network costs are too high, and old equipment need replacing
Networks are complex, hard to scale and interoperate
Operators are tied to vendors for dedicated technologies
Roll-out time for new services is too long
Also customers are pushing for more innovative services

Operators must evolve or become extinct
Option 1: Stick head in sand and ignore the storm
Continue down the same path, upgrade existing kit
Option 2: Evolve
simplify the network (reduce complexity and cost)
become access independent (mobile / fixed)
offer new services quickly and on demand
concentrate on content and services
Most operators seem to have chosen Option 2:
Orange UK and Wanadoo: Test IMS solutions
BT announce : National network migration 2008>
France Telecom: FMC user trials underway
KPN (Netherlands): FMC user trials underway
T.I.M (Italy): IP based Video sharing launched 2005
Telefonica (Spain): IMS deployment begins 2006
… and many more

Operators fight back with NGN
NGN will:
Provide a migration path from traditional network to an
IP based network, whilst maintaining existing services
Reduce COSTS (CAPEX and OPEX), and increase ROI,
(RETURN ON INVESTMENT)
Provide a common foundation for both fixed, mobile
and enterprise services
Allow the quick creation and deployment of innovative
new blended services on demand
Provide flexible dimensioning, that is easily to scale
Allow advanced centralized network control, for
charging, O&M and more
Attract the third party service providers without loosing
control of the network
Open interfaces allow vendor independence, the best
equipment can be chosen for each layer

What is Convergence?
 What is FMC?
 FMC = Fixed Mobile Convergence
 An industry “buzzword” that is used to sell magazine articles
and telecoms conferences
 A technology that is revolutionizing the telecoms world
 Contains:
• Convergence of the “Market”
• Convergence of the “Service”
• Convergence of the “Device / Terminal”
• Convergence of the “Network” (the NGN is at this level)
13
World Class Standards
Convergence of the Market
 Commercial Convergence
 Bundling of fixed, mobile and data subscriptions
 Subscriber can access fixed, mobile, and internet services
from a single operator
 Ideally this would allow for one provider and one bill for
multiple service (unified billing)
 Example: France Telecom turns Orange (01 June 2006)
 France Telecoms’ mobile, fixed broadband, IPTV, and
business services in France and the U.K. will take the Orange
SA brand.
That means the end for the Wanadoo (broadband), Equant
(business services), and MaLigne (French IPTV) brands.
14
World Class Standards
Convergence of the Service
 Service Convergence
 Subscribers access same services regardless of
whether they are using a fixed or mobile connection
 Examples: of hybrid services
 MMS (multimedia messaging) on a fixed or mobile
phone
 Presence services (chat) on a computer or mobile
device
 Email access on a computer, mobile or fixed phone
15
World Class Standards
Convergence of the Device
 Device Convergence (2 types)
 One device may integrate various access types
 This may include Mobile (GPRS or 3G) enabled with wireless
technologies (Bluetooth and/or WLAN 802.11 b/g)
 Also may refer to ‘one device does all’ with enhanced
functions such as music/photo/data

What is NGN?
 What is NGN?
 NGN = Next Generation Network(s)
 An industry “buzzword” that is used to sell magazine articles
and telecoms conferences
 A collection of technologies that is revolutionizing the
telecoms world
 General idea behind NGN
 One network transports all information and services (voice,
data, and all sorts of media such as video)
 That one network is build on top of the Internet protocol (IP)
 “Marketing message” The work on standardizing the NGN is
being lead in ETSI
19
World Class Standards
NGN main principles
 NGNs are structured, and are separated into
functional planes, that include:
•
•
•
•
Access
Transport & switching
Control & intelligence
and service (application)
 Layers are independent - they can be
modified or upgraded regardless of
other functional layers.

Migration to NGN
 Migrating from a traditional network to an all IP NGN is an
attractive option, but it is also a logistical and technical nightmare
 Example: BT 21CN:
• 21CN not limited to UK only, it impacts over 150 countries
• Need to migrate over 25 million customers (in UK alone)
• Transition must be ‘seamless’ with no interruption to service
(especially emergency services) during cut-over
• Rip out and replacing over 150 000 network components
• Already installed 2300km of new fibre in the network
• Reducing 16 independent networks (PSTN/ATM.. ) into ONE
• Complex regulatory issues
• 350 000 customers already migrated to 21CN in South Wales
