Regulatory of VoIP in Korea

VoIP operators need a permission or a registration to operate

Current Comm. Status in Korea

unbundling of the local loopNew entrants do not have to provide their own access network

However, they pay for the use of other operator’s access network

QoS requirement to grant using 070 numberR >= 70, end-to-end delay <= 150 ms, call success ratio >= 95%

MSO was authorized in last November to operateIt may accelerate the bundling

9ITU-T (Future of Voice)

Consideration of Voice

Voice is still the “Killer Application”

The needs for live communication are far deeper than other forms

Voice is still money-making commodity

Re-consideration of Voice

Value of Voice

If people can get the same service cheaper than elsewhere, they will.

Price fell, voice usage skyrocketed

Customer’s behavior

Q) Why is Voice ARPU dropping ?

Increased competition

Fundamental shift in how “value” is realized

If you can’t cheaper, you must be better.

Evolution of Voice

As VoIP offers enhanced features and becomes more widespread,

Re-consideration of Voice

The past : operator-centric The future : user-centric voice in telephone

same services & phone for everyone

price-driven

separation of

communication, information, entertainment

voice in everything

customized services & GUIs

application-driven

convergence of

communication, information, entertainment

Customers’ usage pattern of VoIP will vary significantly

customers will be segmented

11ITU-T (Future of Voice)

The incumbent’s challenges

retaining of subscribers

maintaining profitability and retaining customer loyalty

Re-consideration of Voice

Voice applications

VoIP enabled IT applications

Integrated service of voice and the internet (web)

making rich services for ARPU increase

Segmentation, Branding, & service bundles

Personalized Context-aware services An enhanced interaction is established (user-to-user, user-to-machine, user-to-content)

Context : any information that can be used to characterize the situation of an entity (person, place, object, …) [by Dey, A.K., 2001]
