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
4
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)
5
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
6
How will telecoms looks tomorrow?
Battle for the customers

The times they are a changin
The order is rapidly fadin'.And the first one
now will later be last For the times they are
a-changin'. lt Bob Dylan 1965 gt

• 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 2008gt
• 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

11
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, OM 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)

14
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.

15
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
  

16
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

17
Convergence of the Network

• Removal of distinctions between fixed and
  wireless networks

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

20
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

Migration to NGN is COMPLEX

  services)
• Provides the overall architecture for NGN
• Defines the various subsystems and how they
  interwork

• Resource and Admission Control Subsystem (RACS)

27
Challenge - Maintaining Traditional services over
NGN
IP Users
PSTN Users

• PSTN/ISDN Emulation
• "Provide PSTN/ISDN-like service capabilities
  using session control over IP interfaces and
  infrastructure"
• Emulate a PSTN/ISDN network from the point of
  view of legacy terminals
• PSTN/ISDN Simulation
• "Provides PSTN/ISDN service capabilities and
  interfaces using adaptation to an IP
  infrastructure"
