Emotional needs create new VALUE !

Experience Economy

Variety of tasty coffees,comfortable music,

pleasant atmosphere, pretty mugs…

• Brewed coffee- ¢10~25 a cup• Brand package- ¢25 ~50 a cup• Coffee shop, Take-Out – $ 1~2 • Starbucks - $ 5 a cup

Dramatic increase Dramatic increase in valuein value


Consumer behaviors in Ubiquitous Emotional Society

Tailored consumption that increases the value of individuals!

- Personalization & individualization - Self-Customization

Customers Want What ?

• 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


New Communication Needs in U-society

Communication of Emotion & Sensibility

Then, Next Communication is?

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 enablesto increase productivityto make a variety of cultural exchange to express oneselfto make self-customized service

Increasing demand forHigh-quality multimediaMobileInteractive peer-to-peerDistribution of self-generating content

New trend of communication

New needs for value communication

Communication demand saturated in Korea

Converged Access

Broadband Access• pay for only that I use !• pay only when guaranteed !

Reasonable pricing scheme

• Protect me !• Let me trust you !• Be simple enough for me !

Preventing from negative effects

• Recognize me !• tailored services for me !• unique service for me !

Unlimited expression of users’ personalities


Three Major Challenges and Goals

• network independent open services• convergence services through single unified platform• seamless service in anytime, anywhere

• Differentiated & personalized premium services• E2E QoS incorporating legacy aggregation devices (IP-DSLAM, …) • Fast handover between different IP networks

Low-cost but high-speed technologies100Mbps to 1Gbps per subscriberOPEX reduction through PON based subscriber network
