Mr. Johan Van Egmond, member of the ITU Telecom Board, and member of the
Advisory Board was the chairman of this opening forum.
One year ago he and the forum committee started to construct the conference programme,
at that time they didn’t know how the telecom business would be today. But they knew
that telecommunication was/is an important factor to improve the economy of the
developed and undeveloped countries; and this is one of the objectives of the ITU, to
promote and to create a better road on telecommunication. To help people and companies
on this objective the forum will be divided in three parts:
- The business,
- The policy and regulation,
- The technology and applications.
1.1Forum welcome address
Mr. Henry Tang, Secretary of Commerce. Hong-Kong, China.
To ensure that industry has the confidence to invest in the future, it is important that
governments make their priority to create and conduct an environment for business; we
should provide a stable environment, so that industry never stops taking risks and making
Hong-Kong has benefited from its early and progressive revolution in
telecommunications and has attracted foreign and local investors in its infrastructure. For
the Hong-Kong government investment in physical infrastructure must be complemented
by investment in software and in education.
Hong-Kong government has an important role to play in growing its talents, and for that
it has programs for the training and for the retraining of people, in order to constantly
upgrade themselves and maintain their competitiveness.
The Cyberport is a project to create a strategic cluster of leading IT companies and
professional talents in Hong Kong. To attract professionals to work in Hong-Kong, the
government is dedicated to make Hong-Kong free, safe and friendly to live and to work
Local telecommunication services in Hong-Kong are delivered over fixed networks using
different technologies such as ADSL, fiber to the building or cable modem. On the
wireless telecommunications, Hong-Kong is proud of itself for the coexistence of eleven
mobile networks. Its 2G and 3G operators are free to invest in new networks and to
upgrade them to the latest available technologies. Its public wireless local area network is
getting very popular in places like cafes, shopping malls and airports.
The Hong-Kong government sees a big business potential in the wireless LAN and 3G
1.2Embark on a prudent and pragmatic road to telecommunications
Mr. Jichuan Wu, Minister, Ministry of Information Industry, China.
The global telecom industry has slipped from a decade of high-speed growth into a
recession; many enterprises have gone bankrupt. In contrast, China’s telecom industry
has maintained a healthy growth of 15%. The decline in the telecom industry has created
an impact that has not only affected the industry itself, but also the manufacturing
industry, the capital markets and the financial industry, contributing to the global
economic slowdown and the ongoing recession.
The Chinese telecom industry has modern communications networks characterized by
advanced technology, and it has currently more than 400 million subscribers of fixed and
mobile telephone services. The mobile phones and Internet have become an important
part of Chinese people’s daily life. The healthy development of China’s telecom industry
is attributed to:
- The promotion of IT development, formulating plans in the context of China’s
- In terms of government regulation, to the restructuring of the characteristics of the
industry in order to serve the best interest to the country.
- The reform of the telecom industry, looking to China’s specific needs rather than
copy foreign reform practices without considering China’s requirements.
- The 3G and other technologies.
- The network infrastructure.
The lessons we have learned from the history of telecom development both
internationally or domestically are that when the objective rules of the industry are
respected, the industry will keep developing; otherwise, the industry will be punished.
Now, lessons should be learned from the development and recession in recent years.
1.3Next generation Asian Networks
Yoshio Utsumi, Secretary General, ITU.
Asia has not been affected so much by the current slowdown because is has already
experienced an earlier recession. When Asia faced its own financial crisis in the 1990s,
the leaders decided the best way out was to invest in next generation networks, and to
continue to innovate.
In mobile communications, Asian economies occupy two out of the top three places
worldwide (Taiwan, Hong-Kong and Singapore). As well as leading the world in
broadband Internet, the region is also leading the world in high-speed mobile. In key
areas, such as broadband and 3G mobile, Asia is setting the pace.
The biggest content provider of all is the education sector. Internet makes available to
students and teachers a potential source of educational resources.
The short-term route out of recession is based on investment, but the log-term route is
based on improved education.
1.4Important points for different countries in the forum
Prince Lavaka Ata Ulukala, Prime minister’s office, Tonga.
Tonga is a small country in the Pacific with 100 000 people; this country’s problems
stand from its isolation from the rest of the world, in education, markets, travel and
information. This country has recently introduced telecommunications competition with a
second communication entity. Both entities offer wireless telecommunications and
wireless Internet. The cable speed at the moment is 2 megabits and is planned to growth
up to 11 megabits.
Competition is a very positive point for this country, Mr. Lavaka Ata Ulukala hopes that
new operators will bring broadband, ADSL, and new technologies to his country.
Dr. Mai Liem Truc, Secretary General, Department General of Posts and
The world is changing very fast; the most important point for the development of a
country is the successful management of the change. Vietnam has changed from a central
economy to a market oriented economy to attract foreign investors. In the
telecommunication sector, Vietnam has jumped from a small analog network to a big
digital one. Today it is changing its policy and regulatory issues. Vietnam is managing
successfully the changes from monopoly to a telecommunication competition
Vietnam came to the forum to learn from the experience of other countries.
Mr. Binali Yildirim, Minister of Transport and Communications, Turkey.
The Turkey government has projects of eGovernment, eHealth and eEducation, all of
these are significant factors to accelerate the social development; new projects and
strategies continue to be developed on the national and local sectors. For Binali Yildirim
a good government should be fast, cheap and efficient.
Mr. Michael Binder, Assistant Deputy Minister, Spectrum, Information and
Michael gave a positive vision of the current industry problem.
The competition gives to the consumer low prices and a best product. The demand
(telecommunication, network, etc.) is there and as long as the demand is there the
industry will supply and fulfil this demand. We have to look at technology not as an
industry but as a tool that can be used to achieve both economic and social objectives.
Canada has a strong technology sector that contributes to the growth of economy, jobs
creation and innovation capacity, in all the sectors of the economy.
Mr. Gordon Astles, President, Asia Pacific operations, Cisco Systems, Hong-Kong
For Gordon Astles, carriers are very much focused on the conventional voice, data, video
and getting well provided basic services, but they have to improve to new concepts and
Mr. Noah A. Samara, Chairman and Chief Executive Officer, WorldSpace Corporation,
When we look in real terms at the number of people that are included in the new
technology world and the number of people that are excluded from this digital revolution,
we can see that more than the double of included people are still excluded from this
revolution. Governments and everybody should be focused on how to include this large
group of people. As long as this people are excluded from the technology we will have
their demand, and as long as the demand is there the technology industry will grow up.
2.The 3G Business Case
2.1Revenues from 3G Services: an Asian picture
Ms. Paola Tonelli, Chairperson, UMTS Forum.
The UMTS Forum provides quantitative and qualitative perspectives on the value of
UMTS. Their studies of 3G provide also a comprehensive view of inter-related
technologies. Their studies conclusions are:
- Simple voice will continue to be a vital service.
- On average, willingness to pay is fairly low for mobile data.
- For consumer, MMS is an important service.
- GPRS services can stimulate demand.
- 2.5G and 3G technologies coexist in Asia.
- China and Japan are in the top five most important markets for UMTS/3G.
- Annual 3G/UMTS revenues in Asia Pacific should be $118 Billion by 2010.
- Current MMS market experience makes Asian countries leaders in 3G MMS.
- Users will expect to be able to roam with 3G mobile data services just as they do
- Mobile data services can achieve mass-market adoption when priced correctly,
with adequate handsets and service availability.
Mr. Myung Sung Lee, CTO and Vice President, R&D Centre, Republic of Korea.
Myung Sung Lee gave the number of mobile users in Korea. They expect that all the
services will be increasing in number of users, especially 3G services, which they are
experimenting on. They want to implement 3G. One of the services that they are working
on is the introduction of movies on mobile phones; they will be movies of 2 minutes
They expect to have millions of 3G subscribers and most important, they have already the
infrastructure for that.
Ms. Agnes K. Nardi, Managing director Hutchison Telecommunications, Hong-Kong.
Ms. Agnes was very positive about 3G technologies, in the 80’s a survey about the use of
mobile phones in Hong-Kong came to the conclusion that people would not use mobile
phones, because that was the answer of almost all the people; now, more than 20 years
later, we see that almost all the people have a mobile phone, and here in Hong-Kong
people use their mobile phone, even if the local calls are free. Currently almost all the
people have a mobile phone and that is one of the reasons to be confident in the 3G
3G is quite different from the pure voice telephony of 2G as it is full of excitement
brought by innovation and dynamic evolution.
Mr. Simon Bureau, Managing director, Vectis International Korea, Republic of Korea.
The e-video market has grown these last years, many millions of people now use this
technology; with the number of millions of e-video subscribers we can not predict how
many 3G subscribers we will have; 3G subscribers have decreased to 25% of the initial
expected number at the beginning of this year.
Comparing Japanese and Korean markets, three years ago Japanese had largest handsets,
now, Japanese leads the world in rolling out “third generation” (3G) networks and
services. As the mobile telephony markets in developed Asia gradually saturate,
operators are trying to find new sources. Korean industry is working on mobile colour
screens, camera on phone and mobile games with the aim of wining current Japanese
3.Delivering content and applications
3.1Early adopter: mobile Internet and multimedia services
Dr.Yoo Young Song, Executive Vice President, KT Freetel, Republic of Korea.
Internet has evolved from text to multimedia; the mobile industry in 2 years has evolved
from 2G to 2.5G, now it offers 3G services and multimedia.
The mobile Internet services were focused on contents and it was a text-based service,
now, it is focused on applications and it is a multimedia service, it allows you to
download applications. Shift from contents to applications gives more revenues and
satisfies the customer needs.
The new mobile multimedia services offer MMS (multimedia messaging) and VOD
For Dr. Young Song, the most important thing for young people is music, in Korea they
use BlueTooth to send music, teenagers love that, and there is a big industry to make
money. Teenagers do not have money to pay for music but parents do.
3.2Current mobile marketing in Japan and the efforts of D2C
Mr.Akihisa Fujita, President, D2 Communication, Japan.
I-mode was introduced in 1999 in Japan; since then, this mobile service has become very
popular and it has attracted over 35 millions subscribers. Over 45% of Japanese access
Internet via a mobile phone, and over 25% use I-mode service.
D2 Communications started as a mobile marketing business company, and has now
established itself as a market leader in both marketing theory and practice. In Japan, the
company is developing three types of mobile advertising at present:
- Picture advertising: set up a space in the popular contents of I-mode as banner.
- Mobile mail advertising. Deliver text format advertising on mail news headers to
targeted users who subscribe to mail magazine on their I-mode.
- Paid-publicity advertising.
Mr. Fujita thinks that email and sms are the most important things for people. Providers
can ask money for contents of quality where the knowledge can be improved, or can put
advertising between the contents. But if the service is good, people will pay for that.
3.3Finding the right balance
Mr. Bosco Eduardo Fernandes, Vice President UMTS Forum, Germany.
In the 19th century the perception of year 2000 was very different from what it was, even
from 2000 to now, the perceptions have changed. New needs have emerged.
We need broadband services because people will generate more original information over
the next three years than created in the previous 300,000 years combined. People have
new needs: they already use messaging services (sms, mms) and mobile music finder, for
example, but they need more. The answer for their needs in the near future is IMS, IP-
Multimedia Subsystem. IMS delivers:
- IP-based real-time multimedia communications.
- Full integration of real-time with non real-time multimedia.
- Access to web services.
Mr. Francis Wong, Managing director, Trident Telecom Ventures Ltd, Hong-Kong.
He asks himself where is the money and from whom the money comes, in Hong-Kong
85% of people use mobiles, there are no more customers there, he thinks that money
doesn’t come from customers anymore but from applications, and sending emails is the
largest application which can make money. If a company says that email from mobile is
free, everybody will use it and it will be successful, but that does not make money,
advertising on emails makes money, paying for emails makes money.
Mobile is one of the most secure ways, the SIM card is unique and the person is always
identified, always on a cell. But contents sometimes are not encrypted; the Trident
Telecom Ventures Company is working on encryption.
4.Value-Added Services that make money now
Mr. Fan Zhang, chief Technology officer, China Unicom, China.
China Unicom is an integrated Telecom service provider; it mainly provides Telecom
service, long distance and local distance telephony, Internet, VoIP, etc. Currently China
Unicom has 24% market share of GSM subscribers.
Its CDMA network capacity will be expanded from currently 15 million to 40 million
subscribers by the end of 2003, thus it will become the world’s largest one.
Mr. Graham Thomas, VP Strategic Marketing and Content, Cash-U Mobile
Technologies Ltd, Israel
Mr. Tomas works with Nokia on the development of mobile games.
Currently the sms market makes money, more than 20 millions of sms are sent every
month. Nokia expects that the sms games will make money in the future.
A new market is making money now, more and more people in Korea and in Japan use
games multiplayer with java, it is quite fast and people like it.
MMS will maybe be the next market to make money, but mobile technology has to
support it, and not all the mobile phones support it now, furthermore, there are still
millions of people using old mobiles phones.
Mr. Sung-Jin Kim, Manager, Access Network Development Team, SK Telecom, Republic
Location-Based Services (LBS) is growing to one of the most important services offered
by wireless carriers. There are several mobile location applications such as locating lost
child, emergency call, street directory applications, find fiends with digital map and
digital compass. During the presentation Mr. Sung-Jin Kim enhanced a network-based
location algorithm on Advanced Forward Link Trilateration (AFLT) in repeater area, to
overcome the in-building service accuracy problem without being affected by repeaters.
The idea is to identify base station and repeater with Round Trip Delay (RTD) by
increasing delay time with transmission line.
Mr. Tony Lam, Marketing director, i100 Limited, Hong-Kong
Even if the voice market is full now, i100 Limited company thinks that there is still a big
data market to explore: the New Generation Mobile Lifestyle (NGML). The NGML
introduces data services such as games, email, it offers an exciting world of
communication, entertainment, fun and information. Entertainment is even more
powerful than predicted. The company started this service one month ago and the answer
from users has been very successful. The charges of the service are based on the amount
downloaded rather than the time connected. Using a database that saves that is using
what, the company knows which kind of games one-person uses and can target this
person with more games/advertising adapted to his preferences. And this philosophy
The target of this service is a young customer, usually young generations have parents
who work and who are able to support this cost.
5.The new intelligent network
Mr. Peter Briscoe, Founder, President and Chief executive officer, Convedia, Canada.
The convergence between Internet and telephony is inevitable. Internet is open, is
focused on users; telephony is closed, controlled and reliable. If we put both together we
have the next generation network, which is open, focused on user, fast paced, has
multiple QoS, managed and reliable.
Looking to the past/current situation, we have an old approach of the network, where
each system has its custom hardware running proprietary software. This old technology is
not upgradeable and it is very costly (training, operating, maintaining, etc.), usually
works on a legacy TDM network.
Looking to the future, the new approach is the new generation technology, where it is
easy to add new services, experiment with services, it is easy to scale it up and also
highly reliable and with a long lifespan.
Mr. Masayoshi Ejiri, Vice President, Transport Systems Group, Fujitsu Ltd., Japan.
Technology convergence, dynamic eBusiness requirements and deregulation are
accelerating competition and breaking down conventional boundaries both inside and
outside the telecommunications industry; a single Service Provider (SP) is no longer able
to offer sufficient services to its customers. Today, most telecommunications services are
provided by a multi-SP environment, but this is not enough, multi-SP also needs
collaboration with other partners such as equipment vendors, software vendors, system
The aim of the presentation was to clarify the importance of common business process
components and to indicate those that should be shared and standardized to support the
development of telecommunications management solutions.
Mr. Chris Wylie, Regional sales director, QUALCOMM Internet Services, Hong-Kong.
The QUALCOMM Internet Services are focused on the next generation of wireless
applications, development and services that will combine data and voice capabilities. The
company is a pioneer of CDMA technology, the recognized global standard for next-
generation, digital wireless products and services.
Mr. Chris Wylie thinks that the consumer has to choose the applications he wants to
have, he has to have the possibility of subscribing himself to the services he wants. It is
the market that decides the application, not the industry as in the past.
5.1J2ME: Content from Multiple providers to multiple channels
Mr. Jaider Radhakrishnayya, Independent consultant, Mobile applications and Web
Access points are proliferating from the periphery of an ever-growing core
telecommunications network. Consequently a number of content providers are emerging
to offer applications and services over these channels. In order to maximize the reach of
this content, the platform of development and delivery has to be standardized. This is the
fundamental aim of the Java 2 Micro edition (J2ME).
J2ME key advantages:
- J2ME is an open and controlled specification.
- It is built on Java framework.
- Uses Java commands.
- The original concept of portable code and portable data springs to life when J2ME
works together with technologies such as XMS and Java Messaging Service.
- J2ME makes it possible for upcoming technology trends such as Web Services to
permeate easily into mobile devices.
Those benefits make J2ME an excellent vehicle for service delivery to fixed or mobile
6.Metro Optical Network: Merging the benefits of Ethernet and
6.1Multi-service transport platform optimises the existing network
Mr. Yan Lida, Vice President, Huawei Technologies Co. Ltd, China.
Services providers have always the same dilemma, the cost and the revenue do not grow
aligned; currently they look to the next-generation products to fix the revenue-cost
Why is Metro so hot?
- Because new services demand in the access layer are growing at an unexpected
rate and will generate new revenue streams,
- Because new technologies emerging, are now available as new solutions.
A unified transport platform is critical not only for multi-service transport but also for an
operable network to streamline management and to ensure security.
The Multi-Service provisioning platform (MSPP) reduces the number of network
management systems needed, and decreases the resources needed to install, provision and
maintain the network. There are two different types: Multi-Service Billing Platform
(MSBP) and Multi-Service Transport Platform (MSTP).
MSTP is to optimise the data network, not to replace the data equipment.
- Reduce costs on network operation and network management.
- Improve revenues:
o Realizing fast service provisioning, leveraging the coverage of existing
o Transmission evolves from infrastructure to service network, capable of
providing service, especially for private lines.
6.2Merging the benefits of Ethernet and SDH
Mr. Toshitaka Tsuda, Member of the Board, Fujitsu Laboratories Ltd, Japan.
Today, Ethernet is widely spread not only in the enterprise use but also for home use. For
the operator, providing the Ethernet interface to the customer seems to be an important
issue. The point of view of Mr. Toshitaka Tsuda is that even if Ethernet will be widely
used, Synchronous Digital Hierarchy (SDH) will coexist in the metropolitan network.
This comes from the following considerations:
- There is an SDH installed base.
- Current telephone service will remain as a major profitable service for a while.
- Ethernet support is an essential service that operators will provide for enterprise
customers, but there are other interfaces.
- SDH can provide strict protection and QoS.
- Use of WDM in metropolitan networks is spreading.
- Due to topological restrictions, Ethernet has limitations in scalability.
7.From here to the future: evolving Legacy Networks to NGN
7.1The application of Softswitch Technologies in Next Generation
Dr. Ming Li, Director Engineer, ZTE, China.
In the Next Generation Networks (NGN) voice, data and video services will converge.
Softswitch technologies build NGN and aggregate advantages of IP, ATM, IN and TDM.
Softswitch technologies are a collection of products and services to enable
telecommunication services to run on the data network.
Main characteristics of Softswitch:
- Their open architecture and interoperability.
- Allow service providers or phone companies to select the best solution for their
- Establish connections for end-to-end communications.
- Provide converged services that combine voice, data, video and new services.
- Softswitch solutions coexist with traditional circuit-based switching.
- Independence of services and networks.
Softswitch main changes and efforts:
- Optimise routing on a large scale. Currently Softswitch deploys only in a small
- Operating Support System (OSS). Research on OSS of the Softswitch system is in
- QoS guarantee.
7.2Emerging Technologies: G-MPLS in a Photonic Service Switching
Mr. Debashis Basak, AcceLight Networks Inc, United States.
In the North American telecommunications industry, several innovations must to be
- Simplification of network architectures to improve provisioning and better use of
- Deployment of new switching technologies for more scalable and flexible
- Adoption of protocols that expand the IP control plane capabilities to other traffic
types for more intelligent and flexible networks.
During the presentation Mr. Basak discussed the effect of Generalized Multi-Protocol
Label Switching (G-MPLS) and about a new advanced optical switching technology,
Photonic Service Switching (PSS).
G-MPLS offers the ability to provide a common control to packet, TDM, wavelength and
fiber services allowing full integration of provisioning for all traffic types.
A PSS is an advanced optical switching network element that uses Photonic burst
switching fabric. A PSS used with G-MPLS offers new network architectural choices and
reduces the cost of building and maintaining a network. It can:
- Transport provisioning and protection.
- Consolidate management of packet.
- Deploy intelligent protection and restoration of networks.
- Deliver switched services to the installed fiber infrastructure.
- Provide route selection.
- Manage networks through programmable interfaces.
G-MPLS can be used to improve the efficiency of transit networks, but it offers better
efficiency in PSS networks.
8.Internet Telephony and VoIP
Mr. Eris Erkel, Vice President, Nortel Networks (Asia) Ltd, Hong-Kong.
Packet switching over VoIP is not new; solutions for large network are there. Large and
small enterprises want to offer voice, data and video over IP networks. VoIP is the first
step, and probably the more difficult to develop for operators, but now, operators have a
much better position to implement VoIP.
8.1The Migration to National and International VoIP
Mr. Diarmid Massey, Managing Director, ITXC Corp., Singapore.
If we look at the statistics, we can see that people have not stopped talking, talking on
phones, and also talking over IP, VoIP is already there, operators such China Netcom,
AT&T or BT are using it. In the Philippines 35% of the traffic is VoIP. This gives a
paradigm from old world and new world.
ITXC’s VoIP offers:
- International Voice and Fax Origination.
- International Voice and Fax Termination; new revenue and traffic from new
- National or regional network outsourcing; lower total cost of ownership.
Carriers should use ITXC because:
- It has lower transport costs.
- Increase network efficiency.
- High speed to market/scalability.
- Maintain or increase market share. Get more of the available market, staying
- Increase product/service portfolio.
- The network is already there, companies do not need to change anything.
Mr. Peter Briscoe, Founder and President, Convedia, Canada
Technology is moving from traditional telephony networks to VoIP. The world is in a
transition. Now, the web is not only web browser and static html pages, it is also video,
voice, animated pictures…and VoIP is a good solution. VoIP is still in the start, there are
still many things to develop but there is a big market there, and it is waiting for us.
8.2Implementation of IP Telephony over CaTV
Mr. Haim Laufer, VP Marketing&Sales, comMATCH, Israel.
Cable Television Laboratories (CableLabs) is a non-profit research and development
consortium of cable television system operators representing North and South America.
Cable operators must meet the following main challenges:
- Provide the subscriber with the same level of telephony services and telephony
Quality of Service (QoS).
- Offer a telephony network that is both durable and expandable.
- Offer a short time to market, with deployment as soon as possible.
The optimal solution for meeting the above requirements is to use the concept of Access
Gateway. The Access Gateway combines the advantages of IP technology with the PSTN
Class 5 switch.
Why is an Access Gateway the best option for implementing IP telephony over CaTV:
- The Access Gateway is the only solution that is available immediately.
- The success of IP telephony deployment over CaTV will be based on customer
- Access Gateway offers a minimal-risk solution.
- Access Gateway follows standard components.
Which are the current problems of VoIP?
- Availability of bandwidth, for the moment it is not enough.
- The development of products that enable voice to travel on network packets.
- The understanding of what kind of networks we need.
Why is the delay for VoIP so big?
The analysts talk about a delay of three years, one problem is the standardization, another
one the financial, but there is still the problem that we are not ready to provide the same
level of quality as the digital switch. We cannot sell something that does not work or
works badly. You need a long period of testing. Switch Class 5 will come, but it will take
probably 3 or 5 years.
Is VoIP more developed in rural regions because it is cheaper?
Yes, VoIP is the only solution for undeveloped regions in China. Currently technology is
too expensive for poor regions and they cannot afford it.
What do people want?
People want that when they make a call, there is no echo, no noise that is good service
and quality, for that we need regulation and standards.
Does cheap mean bad?
Cheap is not equal to bad quality. When we call from Hong-Kong to India or Singapore,
the quality is very bad, but when we call to Europe the quality is better. In India or
Singapore there are illegal operators offering cheap calls but with very bad quality.
Not all the cheap calls are over IP, and not all over IP calls are cheap; not all the illegal
operators use VoIP, and not all VoIP is illegal.
India is a special situation, with many illegal and legal operators working at the same
time, the market will decide which operators will survive and which not.
Legislation in each country must work to prevent this, and operators must be regulated,
because operators in some countries don’t declare calls.
Is it good to have competition in VoIP?
When competition exists, new ideas are growing up and new services come to customers.
To be a competitor you need your own network so, to be a big competitor you need to
provide video and voice.
9.When the Next-Generation is the First Generation Built
Mr. Houlin Zhao, Director, ITU.
Service providers are faced with the choice of installing a common transport network for
the delivery of multimedia services, should they?
The panel members will answer this question and will examine the pros and cons of
moving to a pure IP environment.
9.1Evolution to Next Generation Network
Ms. Qi Yin, Director, China network Communications Groups Corporation, China.
The Telecom Market in China has considerably increased since 2000. In 2000, the
number of users using mobile phones was 95 million, now we have more than 200
Next Generation Network (NGN) pros:
- Separation of access, transport, control and service layers.
- Opening of network architecture and interface, and improved standards.
- Unified network platform based on IP/ATM packet switching technology.
- Integration of voice, data and multimedia services.
- Current level of maturity.
- Structure of NGN Network.
- Quality of Service (QoS).
- Security of IP Traffic.
- Killer services and application.
9.2The emergence of IP in CDMA radio access network architectures
Mr. Louis Farina, Senior product manager, GTSS CDMA, Motorola Inc, United States.
After the 1980’s, the computer world has increased in processing power and decreased in
cost; more and more the ability to distribute functionality across platforms flourished as
computer architectures became increasingly more open. These new architectures fostered
interoperability between platforms. In this environment Internet took root for commercial
traffic and propelled the industry towards an IP-based model. The result was cheaper,
more flexible and a scalable architecture. This analogy can be directly applied to the
migration of CDMA radio access networks to an IP-based architecture.
9.3IP based or legacy based networks
Mr. Ngwero Hannington, Engineer, Telkom Kenya, Kenya.
The idea of IP based networks (IBN) is to integrate voice, data and video on a single
network. IBN characteristics:
- Open distributed architecture.
- Standards based.
- Supports abundance of services and applications.
- High availability to provide carrier class performance.
- Flexible in addressing marketplace demands.
- Modular and scalable.
- Enables the delivery of voice and high-speed data services
- Cost reduction, because of the elimination of duplicate unnecessary infrastructure.
- Bandwidth dimensioning is easier.
- Implementing a voice quality bandwidth ensures Quality of Service.
IBN is perceived as insecure (denial of service attacks, etc.), IBN adopters must decide
on the security measures to adopt depending on the threat analysis and risks of their
10.Deploying 3G Wireless
10.1TD-SCDMA 3G wireless communication system
Mr. Huan Zhou, President, Datang Telecom Technology&Industry Group, China.
It was in 1995 that industry started to talk about SCDMA, but it was only in 2000 that
ITU accepted TD-SCDMA as one of 3G international wireless standards.
The TD-SCDMA industry alliance has as mission the integration and coordination of
industrial resources, the upgrade of R&D and the promotion of TD-SCDMA expansion
and application at home and in the global market. Presently, the Alliance is mainly
consisting of domestic enterprises.
Among the mainstream standards, TD-SCDMA possesses the highest utilization rate of
spectrum. TD-SCDMA in the future:
- Will assist operators to realize low-cost and high-quality operation.
- Will provide subscribers in wide segments, environment-friendly.
- Will use Intellectual Properties Rights (IPR) policy.
- Will contribute to China economy as well as world economy development.
Mr. Toni Stadelman, Chief Executive Officer, TOGEWAnet, Switzerland.
TD-SCDMA is a 3G standard.
Wireless will play an important role in the future, it will give a very fast access to
Internet; many people think that wireless is a competition to 3G, but it is not, wireless is a
complementary service to 3G.
Mobile is going really to Internet; all mobile customers want to have Internet access on
their mobiles. Operators and companies must work together to offer a new mobile world
to customers, a world where wireless is joined with Internet, where Internet is joined with
mobiles, where mobiles are joined with 2G and where 2G will converge to 3G.
Dr. Fatih Ozluturk, Vice President of Innovation, InterDigital Communications
Corporation, United States.
The combination of Wideband Time Division Duplexing (WTDD) technology in Third
Generation (3G) networks will bring technological and financial benefits. These benefits
come from the fact that WTDD:
- Is fully and seamlessly integrated with Frequency Division Duplexing (FDD) in
- Supports voice and data applications.
- Offers cost-efficient network deployment.
- Is harmonized with FDD at the chip rate level.
- Optimises high revenue data and voice application.
- Increases throughput and raises overall network capacity.
- Creates significant advantages for network operators, equipment manufacturers
and application developers.
Mr. Toshiro Suzuki, Chief Engineer, Hitachi Ltd, Japan.
One third of the total number of worldwide mobile communication subscribers is in the
Asia/Pacific region. In Japan 60% of the population enjoy mobile communications. And
60% of the Japanese subscribers are using mobile to access Internet. Mobile use is
changing; at the beginning mobiles were used to call, but more and more people use
message communications more than voice.
To broaden the mobile and wireless access bandwidth, there are two approaches. One is
wireless LAN, and the other one is cellular-based, high-rate access including 3G mobile.
Wireless LAN seems to be a very cheap and simple solution to realize wireless access.
For high-rate packet access methods such as CDMA2000 may be more feasible. From the
viewpoints of security and reliable billing, cellular-based networks may have more
11.The Human Interface: Terminals for 3G – Regional Issues with
11.1From Keyboard to the Star Trek Vision
Mr. Bjorn Krylander, Chief executive Officer, UbiNetics, United Kingdom.
The past 10 years have offered limited paradigm shifts. Current paradigms (PDA, Mobile
Phones, Lap Top Computers, etc.) will enable the Mobile Internet, but new paradigms
(phone on glasses, caps or hats with mp3 player inside etc.) for input and output can
extend the mobile Internet to new environments.
At some point in the future completely different concepts for interaction will be used.
Some of those have been around for years but never really made it into the main stream
of usage such as voice recognition, and text to voice conversion, but others will
completely revolutionize the industry.

11.3The Human Interface: 3G Terminals
Dr. Aloknath De, Director Engineering, Hughes Software Systems, India.
The success of the mobile terminal heavily depends on the easy interaction between the
user and the technology. The growing complexity of telecommunication services and
equipment makes this aspect more and more important; this has become essential when
the user has to interact with a terminal. Standards have emerged to solve this interaction.
The 3G companies can use the Human Machine Interface (HMI) technology to customize
background images, fonts, and icons.
