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.
10ITU-T (Future of Voice)
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]
