4. 4 What is VoIP? (1) Voice communication realized on
IP network
5. 5 What is VoIP? (2) Difference from PSTN
Quality of Service (QoS)
IP technology is packet-based & best-effort (not always good for real-time communication)
Constant band width, latency and packet loss within certain range, packets arriving at the same interval, etc.
Methods to measure and evaluate quality:
R value based on E-model (ITU-T Rec.G.107)
End-to-end quality (simple network & intelligent terminal)
6. 6 What is VoIP? (3) Call routing
PSTN: telephone number on signaling network (SS7)
VoIP: IP address on IP network (SIP, H.323)
Terminal location and emergency call
PSTN: bound to the subscribers line
VoIP: could exist anywhere on the network (nomadic)
> could impede realization of emergency call
7. 7 What is VoIP? (4) Interoperability
Not always guaranteed (standardization)
Interconnection
Telephone number is essential to receive call from PSTN
Others
Power supply
Congestion control
Security and lawful intercept
Various services (toll-free, directory service, etc.)
8. 8
9. 9 Overview of the Japanese market (1) Competition was introduced in 1985 (privatization of NTT)
Competition policy
Market size has increased
Price has lowered largely
Current major trends:
Fixed to mobile
Telephony to IP
10. 10 Overview of the Japanese market (2) Telephony to IP
The number of ISPs: 9,111
The number of Internet user: 79 million (62% of population)
Broadband
ADSL has become common in many areas (high-speed at low price)
Recently FTTH is growing in urban area
11. 11 Overview of the Japanese market (3) Transition of the legacy networks
KDDI
Replace all the networks to IP by the end of 2007
NTT
Replace 30 million metal subscribers lines (half of all the subscribers lines) by FTTH by 2010
>> Total cost would decrease by providing both data and voice on the same IP network
12. 12 Overview of the Japanese market (4) Reform of the Telecommunications Business Law
From ex-ante to ex-post
Relaxation of market entry/withdrawal (from approval to registration/notification)
Abolishment of the classification of telecommunications carriers by facilities
Strengthening of rules for user protection
13. 13
14. 14 VoIP regulation in Japan (1) Rapidly increasing VoIP
Telephone number used for VoIP :
10.6 million (December 2005)
VoIP number (050): 97.5 million
Fixed phone number: 8.5 million
Light-touch regulation
Mainly regulated by numbering
15. 15 VoIP regulation in Japan (2) Classification of VoIP service
1. Telecommunications service
Fixed telephone number
VoIP number (050)
Without telephone number
2. Nontelecommunications service
P-to-P application on the Internet
16. 16 VoIP regulation in Japan (3) VoIP number (050-XXXX-XXXX)
Since September 2002
Receiving call from PSTN was realized
Minimum QoS
R value>50, latency <400ms, controlled network
Minimum facilities installation
Installation of facility and network being controlled by service provider
Interconnection with PSTN dominant carriers (NTT regional)
No constraint on terminal location
No duty to provide emergency call
17. 17 VoIP regulation in Japan (4) 050 VoIP market
Provided as adjunct service of ADSL
Mainly used as secondary telephone service (not as a substitute for PSTN)
29 carriers (March 2006)
Some providers offer free call service among users
However, impact on PSTN is limited
Incomplete interconnectivity
Lack of emergency call
18. 18 VoIP regulation in Japan (5) 050 VoIP market
Light touch regulation > smaller investment to start business
Increased competition in ADSL market
World fastest and cheapest ADSL service for users
Less profit for carriers (some carriers move to FTTH market for profit)
New innovative service using nomadic nature is expected
19. 19 VoIP regulation in Japan (6) VoIP with fixed phone number
Since September 2004
Service equivalent to PSTN
PSTN equivalent QoS (R value>80, latency<150ms)
Installation of facility and network being controlled by service provider
Interconnection with PSTN dominant carriers (NTT regional)
Location-fixed
Emergency call
Facsimile sending and receiving, etc.
20. 20 VoIP regulation in Japan (7) Fixed phone number VoIP market
Provided as adjunct service of FTTH
Used as primary telephone (as a substitute for PSTN)
13 carriers (March 2006)
Becoming popular lately as FTTH expands
So-called triple play service
Primary telephone service
High-speed Internet connection
Video streaming (television program)
21. 21 VoIP regulation in Japan (8) Major difference from 050 VoIP
PSTN equivalent telephone service (including emergency call, facsimile sending and receiving)
Number portability (allows users to change service provider while retaining number)
>> Enable users to switch from PSTN plus ADSL to FTTH
22. 22 VoIP regulation in Japan (9) Users
PSTN equivalent telephone service (without changing number)
Higher speed Internet connection (than ADSL)
Reasonable cost by canceling existing PSTN (price of FTTH is decreasing gradually through competition)
Operators
Seek profit in FTTH market by integrating plural services (ADSL market becomes competitive)
23. 23 VoIP regulation in Japan (10) VoIP service without number
1. Telecommunications Business
PC-to-phone or PC-to-PC service without number
>> Common duties of telecommunication service are applied
2. Non-telecommunications Business
P-to-P application on the Internet (Skype)
>> Announcement (to caller) in case of forwarding call from public network to P-to-P

25. 25 Perspective (1) VoIP
VoIP could provide voice communication at a much lower cost than PSTN
VoIP could largely enhance socio-economic development
VoIP has a potential to give a large impact on the current telecom market and to change the market structure drastically
However, transition of the existing network to IP is a global trend and would be required in future eventually
26. 26 Perspective (2) Light-touch regulation
It took many years to develop PSTN with various different features
Technical nature (location-fixed)
Social requirement (universal service provision, congestion control, intercept, etc.)
VoIP is not mature technology compared to PSTN (under development)
>> Light touch regulation seems reasonable to enhance the development of VoIP technology and market
27. 27 Perspective (3) Importance of regulation
On the other hand, certain level of regulation is essential for orderly development of market and customer protection
Especially regulation for primary telephone service would require careful consideration
In case of Japan, regulation of VoIP with fixed number is based on technological neutrality as substitute for PSTN
28. 28 Perspective (4) From legacy network to IP
Transition is challenge for many countries
VoIP might take on important position
Infrastructure deployment and maintenance of legacy network during transition is required
Various financing options including public private partnership
Financial capacity of PSTN carriers or assistance from Universal Service Fund
29. 29 Perspective (5) ICT market trend
Competition is useful to increase productivity
However, considerable amount of investment is required for network transition
ICT is a network industry with the characteristics of network externality and economy of scale
Consolidation of telecom carriers is taking place in the world
30. 30 Perspective (6) ICT: socio-economic infrastructure
Reliable, affordable and universal ICT access is important for balanced socio-economic development
Adequate balance between market economy and government policy would be necessary
Effective national dialogues
Cooperation among stakeholders (government, private sector, civil society, etc.)
