  1. E-Commerce, V-Commerce and the Network Convergence Armando Barbieri

  2. 1/3 2/3 1999: Joint Venture between Promon and CPqD

  3. Not for profit private lab. Spin off from Telebrás • ~970 employees • The most important Latin American research and development center in telecommunications. • Branch office in San Jose, CA

  4. Brazilian Group founded on 1960 • Employees have 100% of stocks • 1.200 employees • Activities in Brazil and abroad: • telecommunications • electric power • infrastructure for oil and gas, petrochemicals, mining, metallurgical areas • steel and manufacturing industries • public works

  5. Trópico S.A. • Brazilian switching manufacturer • 8.5 million digital lines installed all over Brazil ( 25% market share). • Staff around 500 employees, 40% of them fully dedicated to product development and support. • Investing heavily in new VoIP technologies: • Carrier Class SoftSwitch • IP-based Remote Access Units • New VoIP service platforms

  6. Trópico S.A. • First Digital Switch in commercial operation in Brazil • First SoftSwitch in live network demonstration in Brazil • Biggest contract for a VoIP network: • CTP in São Paulo (500000 subscribers)

  7. Points to be discussed • How multimedia can help e-commerce? • How telephony and e-commerce will be integrated? • How the Network Convergence will help services that drive e-commerce? • What’s V-Commerce? • What’s a Voice Portal? • How can it be related with Internet?

  8. How multimedia can help e-commerce?

  9. “Click to Talk” Service • Someone browsing an e-commerce site clicks a hiperlink to talk with an operator. • A voice over IP session is established between the PC and the operator. • The operator can be in a call center(a “Web Call Center”) • The operator talks with the customer and remotely assists him navigating through the site.

  10. Click to Talk and e-Commerce • It helps to give confidence to the customer, clarifying doubts. • Can be fundamental in the sale process. • It is totally adherent to the “Next Generation” Converged Voice over IP Network

  11. ...and what is V-Commerce? • V-Commerce stands for Voice Commerce • It is based in a totally automated dialog between the customer and the system. • It allows the user to access the system through a voice terminal or though a multimedia terminal. • It is totally adherent to the “Next Generation” Converged Voice over IP Network

  12. Convergence of what??? Today there is a convergence trend: • Media Convergence: Multimedia • Terminal Convergence: Computer, TV, Video-game, Celular Phone, PDA... • Providers Convergence: Mobile and Internet, CATV and Internet, Telephony and Internet, Internet Access and Content Provider, Content and Application Service Provider • Services Convergence : Several Integrated Services (ex: Unified Messaging, Multimedia Conference) • Network convergence:Telephony and Data

  13. Network Convergence • Trend to converge Telephony and Data to a single network. • Target Network: A network based on IP with controlled and Differentiated Quality of Services. • Why IP?-Internetworking

  14. Internet Protocol • The only protocol present in the access and in the core of the network • Allows transport of any media • Allows a cheap corporate and residential Multimedia Terminal: the PC

  15. Why to converge?Forecasted Growth: Data and Voice Data Traffic Voice Traffic 120000 100000 80000 Terabytes / Month 60000 40000 20000 0 1998 1999 2000 2001 2002 2003 2004 2005 Fonte: Analysys, 1999

  16. Convergence of Telephony and IP Networks: • Transport using Voice over IP (VoIP) • Use of Interworking Gateways(to interwork with the legacy) • Use of VoIP terminals (CPE) CPE: Customer Premisses Equipment

  17. V V A simplified model of the network IP Network Router RGW RGW IP Phone TGW TGW PSTN TGW: Trunking Gateway RGW: Residential Gateway

  18. Trunking Gateway and Residential Gateway requirements: • Voice encoding with bandwidth compression. • Voice packaging • Transparency for voice, tones, fax and modem(Universal Port concept)

  19. Needs a SoftSwitch Network Requirements: • Call Control: • Simple, Efficient, Centralized • Easy addition of service platforms • Billing function secure and reliable • Interworking with legacy: • Inteligent Network (IN) • Common Channel Signaling (SS7) • Interoperability among several types of Media Gateways (H.323, MGCP, SIP)

  23. What this Converged Network has to do with V-Commerce????

  24. Voice Portals

  25. Voice Portals • Interactive access to Internet content through a voice interface using advanced speech processing. • Also known as: • Voice Browsers • Voice Web • V-Services

  26. Example of Services • Companies like Tellme, BeVocal, Quack, Audiopoint, Telsurf are providing services: • Directory Assistance (auxílio à lista) • Traffic Information • Stock Quotes (cotação de ações) • Sports (placar de esportes) • Flight Information • Horoscope • Weather • Driving Directions • Movies • Restaurants

  27. Business Size • Kelsey Group: “Voice Portals will generateUS$ 12 Bi up to 2005 through advertising, e-commerce, HW+SW sales and telephony service (from this amount, US$ 4.6 Bi in advertising and transactions)”. There will be more than 128 million voice portal users by the end of 2005. • Data Corp.: “In 2004, 600 Million users will connect to Internet through PCs, but 1.4 Billion will connect through mobile phones, and other 1.4 Billion through black phones”.

  28. Justificatives for voice-based access • Easier access to a telephone than to a computer connected to the Internet. • Overwhelming growth of the mobile phones • Telephones can be used anywhere • The voice interaction improves navigation, since minimizes the physical limitations of the keypad and display. • Allows access to disabled people

  29. WAP Integration • Users can choose between answering via keypad, touch screen or via a voice command • Users can access the Internet using voice sinthesis, pre-recorded audio and speech recognition, being possible to complement the interface through the keypad and the small display. • The voice interaction can help the WAP browser.

  30. Example: • VP: Welcome to Voice Portal. Can I help you? • What are my options? • VP: You can have traffic information, restaurants, flight information , horosc...... • I’d like restaurant information. • VP: Where you are? • I’m in Porto Seguro, 118 Jandaias street • VP: We have “Tô atoa”, “Pirão”, ... • Where is “Pirão”? • VP: It is in 54 Yareê Street..... • Send the address to my celular and connect me to “Pirão restaurant”.

  31. Internet PSTN Network Model (V-xML server) (V-xML server) Voice Browser A Web Site with appropriate voicecontent and dialog logic (V-xML Client )

  32. Internet PSTN How it is done: Voice Browser VoIPGateway Speech recognition V-xML Client Voice Sinthesys (V-xML servers) Site with V-Services content

  33. Internet PSTN How it is done: Voice Browser VoIPGateway Speech recognition V-xML Client Voice Sinthesys (V-xML servers) Site with V-Services content

  34. IP / ATM Trunk Trunk PSTN Compatibility with OPT architecture SS7 SIP Voice Browser SoftSwitch MGCP MGCP SS7 SS7 VoIP VoIP Gateway VoIP Gateway Site V-xML

  35. Conclusions: • There is a trend to converge to IP due to cost reduction and possibility of new services • The Open Packet Telephony (OPT) allows introduction of services independently of the call control layer and transport layer • Voice Portals use voice browsers based on voice synthesis and speech recognition for navigation • Voice browsers are a kind of Media Server in the OPT architecture
