0. Introduction – VoIP Regulation in Korea

▣ Korean Government has deregulated Internet phone service (so

called “VoIP service”) in the fixed-line telecommunications market

several years ago.

◈The VoIP service is categorized “facilities-based

telecommunication service” in Korea

▣ Regulation for the VoIP service, which is adopted firstly under fixed

line environment, has entered a new phase because there are much

needs for introducing VoIP under mobile environment

▣ Hence

◈There would be new regulatory issues arising when the mobile

VoIP carriers enter the mobile service market

◈It is necessary to prepare the best scenario to continue or

improve market performance under new market environment

� VoIP has already been introduced in Wi-Fi, and cellular & Wi-Fi convergence has

reached the level of seamless handoff support

� The portable Internet (WiBro) was introduced in Korea for the first time in the world,

while the adoption of the mobile WiMAX will be prevalent worldwide in near future

New WiMAX version will support the mobile network.

- In-Stat(2005) forecast that the WiMAX service will secure 8.5 million subscribers by 2009

and more than half of the subscribers to WiMAX will subscribe to the VoIP bundled with

WiMAX

3. Players in Korea(1)

▣ SK Telecom: Korea’s first mobile operator

◈SK Telecom is considering the strategy of combining new functions like the WLAN

with the cellular in order to cope with KT’s ‘Onephone service‘,

◈However, no specific alternatives were taken against it after when KT’s

‘OnePhone service’ had not been welcomed by the market

◈Additionally, SK Telecom cannot carry out proactive marketing for its mobile VoIP

since it is deemed to encroach on the current mobile market.

▣ KT group: equipped with both fixed and mobile service capability

◈The mobile VoIP service at the KT Group level is considered from two viewpoints –

it may encroach on the revenues of current mobile phone or secure mobile

competitiveness.

▣ LG Telecom: the third mobile operator in Korea

◈Focusing on increasing the number of current service subscribers

◈Planning the mobile VoIP service as low price strategy

▣ VoIP, once a complementary goods market of the fixed line phone

◈When VoIP service was first introduced into the fixed line phone

market in Korea, it could not compete with the regular fixed line

phone in terms of quality and phone number assignment, and

VoIP service created a complementary goods market.

▣ Now a replacement for the fixed line phone

◈Quality improvement and number assignment will provide VoIP

service with a viable replacement for the fixed line phone, and

therefore the size of the entire market becomes smaller

◈Consequently, the same level regulation applied to the fixed line

phone will be applies to the VoIP service

▣ Mobile VoIP was also a complementary service market of the mobile phone

◈WLAN version of VoIP service cannot compete with the regular mobile

phone market in terms of quality and phone number assignment, and

creates a kind of complementary service market, just like in the fixed line

phone market

▣ However mobile VoIP could be a replacement for the mobile phone

◈It is natural that mobile VoIP replace the current mobile phone only if its

quality enhances with the number assigned.

◈Consequently, new regulatory issues are arising for the mobile VoIP

◈However the mobile phone environment is different from the fixed line

phone because the incumbent mobile operator paid somewhat expensive

spectrum allocation fee

the case of VoWLAN

▣But in case of mobile VoIP, this service will compete with the

mobile service in relation with the area of coverage extending

and the quality improving

◈In that case, 010 number is possibly assigned for

preventing customers from being confused

◈In addition, spectrum assignment charge could be

recalculated in the viewpoint of the principle of equity

▣It is natural to launch mobile VoIP service in

telecommunication business area

◈For customers, to provide voice services with

reasonable cost

◈For fixed–mobile convergence service providers,

with new business opportunity

▣However, the success depends on the competitiveness

of service providers and adoptability from users

▣Mobile VoIP (Voice over WLAN/WiBro) can be

regarded as: 1) technology evolution, or 2) a

telecommunication service

5. Summary & Suggestion

▣For better market performance and safe landing of

MVOIP

◈MVoIP should be defined as a technology

evolution of WLAN or WiBro

- Incentives to invest his network & can do his own

differentiated business

◈In addition, it is necessary to assign ‘010’number

to mobile VoIP service in order to increase service

quality and decrease customers’ confusion caused by

complicated number system
