  1. 1. UNIVERSITE LIBRE DE BRUXELLES FACULTE DES SCIENCES SERVICE TELEMATIQUE ET COMMUNICATION ITU Telecom Asia 2002 Hong-Kong, 2-7 December 2002 Ines Martinez Moreno Faculté des Sciences ULB - Rapport STC Service Télématique et Communication 03-10 CP 230 - Blvd du Triomphe mai 2003 B-1050 Bruxelles
  2. 2. ITU Telecom Asia 2002 Hong-Kong, 2-7 December 2002 Inés Martínez Moreno, ULB/STC 1.Opening forum 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 investment decisions. 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 in. 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 services.
  3. 3. 1.2Embark on a prudent and pragmatic road to telecommunications development 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 specific needs. - 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.
  4. 4. 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 Telecommunications, Vietnam. 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 environment. 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 Telecommunications, Canada. 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 new technologies.
  5. 5. Mr. Noah A. Samara, Chairman and Chief Executive Officer, WorldSpace Corporation, United States. 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 with voice. - 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 long. They expect to have millions of 3G subscribers and most important, they have already the infrastructure for that.
  6. 6. 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 technologies. 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 markets. 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 (Video Streaming). 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.
  7. 7. 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. - VoIP. - 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.
  8. 8. 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 of Korea. 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 makes money. The target of this service is a young customer, usually young generations have parents who work and who are able to support this cost.
  9. 9. 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 integrators, etc. 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.
  10. 10. 5.1J2ME: Content from Multiple providers to multiple channels Mr. Jaider Radhakrishnayya, Independent consultant, Mobile applications and Web services, Singapore. 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 communication devices. 6.Metro Optical Network: Merging the benefits of Ethernet and SDH 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 mismatch. 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.
  11. 11. MSTP benefits: - Reduce costs on network operation and network management. - Improve revenues: o Realizing fast service provisioning, leveraging the coverage of existing networks. 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 Networks 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 specific needs. - 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.
  12. 12. Softswitch main changes and efforts: - Optimise routing on a large scale. Currently Softswitch deploys only in a small scale. - Operating Support System (OSS). Research on OSS of the Softswitch system is in progress. - QoS guarantee. 7.2Emerging Technologies: G-MPLS in a Photonic Service Switching Architecture Mr. Debashis Basak, AcceLight Networks Inc, United States. In the North American telecommunications industry, several innovations must to be implemented: - Simplification of network architectures to improve provisioning and better use of resources. - Deployment of new switching technologies for more scalable and flexible networks. - 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.
  13. 13. 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 sources. - 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 competitive. - 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.
  14. 14. 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 satisfaction. - Access Gateway offers a minimal-risk solution. - Access Gateway follows standard components. 8.3Questions 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.
  15. 15. 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 million. 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. NGN cons: - Current level of maturity. - Structure of NGN Network. - Quality of Service (QoS). - Security of IP Traffic. - Killer services and application.
  16. 16. 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 networks.
  17. 17. 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. 10.2WTDD technology 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 standards. - 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.
  18. 18. 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 advantage. 11.The Human Interface: Terminals for 3G – Regional Issues with Next-Generation 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. 11.2The iMagic T688: Technology with a Human Face Mr. Justin Tsang, Executive Director, iMagic Systems Ltd, Hong-Kong. The current economic situation has compelled many enterprises to review the way in which they acquire, serve and retain customers. Enterprises must find cost-effective ways to implement sales and marketing strategies without sacrificing standards of quality of service. iMagic is a developer and provider enterprise of advanced multimedia public access solutions. The company created the PowerPhone, the first world commercially deployed “web payphone” solution. PowerPhone combines Internet, telephone, video conferencing, payment and network management technologies into a single point of access.
  19. 19. iMagic T688 is a 15” touch screen that has: - External speakers. - Video camera. - Telephone handset. - Integrated ticket printer. - Media drive. - Card reader. 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.
