  7. Society of Emotion & Sensibility Facility intensive Mass Production Labor intensive Information intensive Knowledge intensive Small Q’ty Batch Prod’n Emotion intensive Personalized Production QC Information Age, and the next? Words for next society The Dream Society1) The Experience Economy2) emotional management emotional marketing, experience marketing 1) Rolf Jensen – Futurologist, manager in Futurology Research Institute 2) B. Joseph Pine II / James H. Gilmore -Strategic Horizons LLP Founder

  8. $ 6.0 • Brewed coffee- ¢10~25 a cup • Brand package- ¢25 ~50 a cup • Coffee shop, Take-Out – $ 1~2 • Starbucks - $ 5 a cup $ 5.0 $ 4.0 $ 3.0 Variety of tasty coffees, comfortable music, pleasant atmosphere, pretty mugs… $ 2.0 $ 1.0 commodity goods service experience Experience Economy Emotional needs create new VALUE ! Dramatic increase in value

  9. 1 Taste to 10 persons • price competition • brand competition • reasonable consumer • clever consumer 10 Tastes to 1 person • value competition • personality competition • emotional consumer • profit-making prosumer Customers Want What ? Consumer behaviors in Ubiquitous Emotional Society Tailored consumption that increases the value of individuals! - Personalization & individualization - Self-Customization

  10. Increasing demand for • High-quality multimedia • Mobile • Interactive peer-to-peer • Distribution of self-generating content • Monthly communication expenditure; $130/household; • (average expenditure of America, England, German, $65/household) • Portion of total expenditure; 6.5% • (3 times of OECD countries) • 12 million of Internet users • 38 million of mobile phone users • Communication that enables • to increase productivity • to make a variety of cultural exchange • to express oneself • to make self-customized service Then, Next Communication is? New Communication Needs in U-society New trend of communication Communication demand saturated in Korea New needs for value communication Communication of Emotion & Sensibility

  11. New Requirements for BcN

  12. PSTN control Internet control Interworking BcN Mobile network control One-Phone Broadcasting Network (CATV, satellite/terrestrial DMB) control Direction of BcN Evolution BcN Phase 1(2005~2007) :combined & interworking Service fixed: 50~100Mbps, mobile: 50Mbps~ per AP individual management of billing/subscribers/services • Broadband Access • E-PON/WDM-PON • WiBro Access • early Open API

  13. Integrated BMS BcN IGWF IGWF Internet IGWF IGWF Mobile network IGWF Broadcasting network IGWF • IGWF : Integrated GW Function • BMS : Business Management System Direction of BcN Evolution BcN Phase 2(2008~2010) :Integrated service composite service on a single I/F integrated management of billing/subscribers/services • Including inter-operability on a single user I/F integrated call base IP Billing • Integrated Service Management - integrated AAA - integrated service policy - Integrated billing • Integrated Service Control • Integrated Fixed & Mobile Access • Managed IP Transport

  14.

  15. Background of BcN project • Vision of BcN • Overview of BcN Architecture • Concluding Remark

  16. Open API Open service Access authentication, Service authorization Service Mediation • Recognize me ! • tailored services for me ! • unique service for me ! Service & Control SLA based unified billing SLA management Service policy management Real-time mobility control Broadband Access Next-generation Access • pay for only that I use ! • pay only when guaranteed ! Converged Access Ubiquitous Access User/service recognition Individual user/service-level QoS • Protect me ! • Let me trust you ! • Be simple enough for me ! Real-time usage monitoring High performance Unified transport Real-time QoS monitoring Network security Network protection/ Reliability Direction of developing BcN Unlimited expression of users’ personalities Reasonable pricing scheme Preventing from negative effects

  17. Service and Control Convergence New IP Transport Access Network • network independent open services • convergence services through single unified platform • seamless service in anytime, anywhere • Low-cost but high-speed technologies • 100Mbps to 1Gbps per subscriber • OPEX reduction through PON based subscriber network • Differentiated & personalized premium services • E2E QoS incorporating legacy aggregation devices (IP-DSLAM, …) • Fast handover between different IP networks Three Major Challenges and Goals
