Basic Components of Communication Networks
• Following 8 major components can be identified– Geographical Location & Terminal – Access Networks– Local Exchange– Domestic Transport Network– International Exchange– International Transport Network– Other Country International Exchange– Other Country Domestic Network (With the similar
components as above)
Communication Network Paradigm Shift
• Present– Transport Network
• OF– Access Network
• Shift from Copper to Radio (3G, EvDO) & Fiber• Immediate Future
– Shift from Radio/OF to Power Line Communication System (PLC) depends upon which revolution comes first in future i.e. Transport or Energy (If energy comes first, access will not be PLC, but radio & OF)
– Hence most promising access network for next 10y will be either Radio or OF or PLC. Cu network will gradually phase out.
– Most promising transport network will be OF especially undersea OF cable systems

Matching the Demand with Available Facilities
• Inter-continental traffic appears to be comparatively lower than the already installed designed capacity
• Certain segments are saturated with designed capacity.– E.g. Traffic via Middle-East from Asia to
Europe– This indicates the market trend in Asia and
Middle East is much faster than Africa
Most Promising Future Transport Media and where it applies
• Transport: Optical Fiber (Especially for International transport Undersea cable)
• Huge development in Asia and Asia towards Europe
• The technology used in the Optical Fiber will be changed from TDM (Time Division Multiplexing) to IP

Global Evolution of Technology• Presently Services such as Telephone, Internet, TV is having separate
networks and sometimes separate access networks to the Home. This paradigm will be shifted to a unified equipment to provide all the services through one access network to be delivered to home.
• Hence Integration of all services through access network will be a global experience in time to come.
• Technological development of Access Networks– Copper wireless (3G, CDMA, Wi-Fi, Wi-MAX)– Copper FTTH IPTV – for provisioning of high bandwidth
• Technological development of Transport Networks– PDH SDH, – Reliability – Self healing Rings, ASON (Automatically Switched Optical
networks), OTN (Optical Transport Network)• Technological developments in inter-oceanic networks
– Coaxial Fiber– Repeaters Optically Repeated Systems Repeater-less Systems– Single Channel Multi-Channel (DWDM)– 2.5Gbps 10Gbps 40Gbps

Observations on present voice applications
• Voice traffic is increasing, out of which mobile traffic carries around 60%
• Revenue ratio Voice to Non-voice is 80:20• Even in Sri Lanka we observed the similar
pattern• The trend of technology for voice traffic will shift
from TDM to VoIP• The trend for the pricing will be independent of
the volume, but dependent on Bandwidth

• What is NGN ?• Future Communications Network• NGN Architecture Design Principles• Why IMS in NGN ?• Evolution of core network towards NGN
Chapter 5Next Generation Networks
What is NGN ?• NGN = Next Generation Networks• One network carrying all information and
Services such as voice, data, video, all sorts of media etc.
• This network is built on top of the Internet Protocol (IP).
• Service-related functions are independent from underline transport-related technologies.
• Supports generalized mobility which will allow consistent and ubiquitous provision of services
22
Definition of Next Generation Network (NGN)
A packet-based network able to provide 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 enables unfettered access for users to networks andto competing service providers and/or services oftheir choice. It supports generalized mobility whichwill allow consistent and ubiquitous provision ofservices to users.
Main Principles of NGN• Structured and separation in to functional planes:
– Access Layer– Transport & Switching Layer– Control & Intelligence Layer– Service/Application Layer
• Control & Intelligent and Transport & Switching Layers are shared by:– Different access types (RAN, Fixed…)– Service layers
• Layers are independent, hence they can be modified or upgraded regardless of other functional layers

NGN Architecture Design Principles
• NGN adopted an sub-system oriented approach which enables– The addition of new sub-systems in the future in order to
facilitate new demands and services– The absorption of sub-systems from other standardization
bodies– High level of flexibility
• IP connectivity is provided through two sub-systems– Network Attachment Sub-system (NASS)– Resource and Admission Control Sub-system (RACS)
• Service oriented sub-systems are also included– IMS is suitably adopted to facilitate xDSL based access network
requirements supporting multimedia services and PSTN/ISDN simulation
– A PSTN/ISDN Emulation subsystem specifically tailored to allow TDM equipment replacement, while keeping legacy terminals unchanged.

Why IMS in NGN ?• IMS generally fulfills the NGN requirements for
conversational services–Managed, carrier operated telecom network–IMS Release 6 becomes applicable to a range of access network types (3G RAN, WLAN)
–IMS is access technology independence
• Telecom industry benefit–Will enable simple and effective inter-working between Cellular and Wire line
–Growing IMS market, encouraging greater usage–Wider choice of IMS suppliers–Market stimulation, decreasing costs (thanks to shared development/deployment costs)
Transition to NGN (1)• NGN advantages:
– Transport network simplification (common CS/PS backbone),
– No transit layer,– Common signaling (signaling over IP, SIGTRAN),
26
Transition to NGN (2)
• NGN advantages:– Transport network simplification: R5 common– CN/RAN backbone
Role of Future Networks – NGN & IMS
• Session control independent from access• Unified session control, user profile• Unified service platforms; QoS• Low OPEX, faster services introduction• Convergent and richer services

• A number of innovative Broadband Wireless Access (BWA) systems are emerging (e.g., WiMAX, WiBro, WiBree).
• They also use variants of OFDM on the air interfaces.• There is growing industrial interest for Mobile and
Broadband Wireless Access offerings to co-exist within the same core infrastructure.
• These broadband wireless technologies are also converging.
WiBro = Korean flavour of WiMax 802.16eWiBree = Nokia enhancement to Bluetooth OFDM = Orthogonal frequency-division multiplexing

• Migration between generations• Comparison of 3G and 4G Parameters
Chapter 7Migration of RAN to 4G
Migration between generations• 1G environment = little capacity, telephony for everyone as objective.
– Easy introduction as voice is a service natural for everybody (killer application?)
2G 3G• 2G environment = large capacity: almost everybody has access to the
technology, wideband multimedia for everyone as objective. WLANs are almost everywhere at cheap costs.
– Difficult introduction as data services on mobile is not natural (no killer application so far).
3G 4G• 2G + 3G + WLANs + … environment = huge capacity, many radio
standards (GERAN, UTRAN, WiFi, WiMAX, WPANs, …): most people has access to multimedia services, broadband wireless access for everyone as objective. WLANs, cellular systems are almost everywhere at cheap costs and with high bit rates.
– Very difficult introduction as users are accustomed to access data services at almost no cost (niche applications?).
35
4G - What is it?• 4G = 4th Generation mobile communications• 4G = B3G = Beyond 3rd Generation (UMTS, IMT-2000) mobile
communications• Foreseen to become available after 2010.• ITU Recommendation ITU-R M.1645:
= mix of many interacting systems is foreseen - not one standard.• Targeted data rates (with wide area coverage and significant
mobility) are in the area of 50 to 100 Mbits/s.
Systems beyond IMT-2000 will be realized by functional fusion ofexisting, enhanced, and newly developed elements of IMT-2000,
nomadic wireless access systems and other wireless systems, withhigh commonality and seamless interworking.
4G Requirements• High data rate transmission:
– Down Linl: 100Mbps– Up Link: 20Mbps.
• Larger system capacity: e.g.,– 3G:1.2Mbps/1MHz and 6-sector-BTS– 4G: 5-10 Times to 3G.
• Lower cost/bit,• Wireless QoS control:
– Non Real Time Service– Real Time Service– Multi-Cast Service.

Present Legacy Applications• Different IT Systems for different applications
such as Billing Support System (BSS), Operation Support Systems (OSS), Mediation Management Systems, Finance Systems, Inventory System, E-Tendering System, Access Control of Call Centers,
• No overall information (360° view) with regard to a customer
• Multiple Platforms• More operational costs
Operators’ Future Expectations• Simplified architecture (Enhanced Telecom
Operation Map – eTOM)• eTOM recommends 4 Major Systems to be
integrated in to one environment i.e– OSS (Operation Support Systems )– BSS (Billing Support System )– CRM (Customer Relation Management)– ERP (Enterprise Resource Planning)
• Above systems are integrated through Enterprise Application Integration (EAI)
• Concept of Service Oriented Architecture (SOA)

Conclusive Remarks
Conclusive Remarks• Mainly depending on the voice revenue• Revenue stream transition from voice to data• Most of the countries are emerging free voice calls,
hence the traditional revenue is under threat• The trend to convert voice to data is under way and can’t
be stop, hence better to plan now for the conversion• 21st Century Communication Networks will converge
most of the services to be enjoyed by the Customer with a single bill.This is New Wave deriving from the Communication Explosion Revolution that we are experiencing now!
46
Conclusive Remarks…• Customers expectations and requirements are
increasing: more services, but single bill
• Telecoms networks are getting faster, bandwidth is no longer an issue
• Main issue is not about networks or technology, but content and services ?
• Convergence is inevitable
• IMS is at the heart of the converged networks, NGN
• Robust and open global standards are essential to the long term success of the NGN
