What is NGN ?
Core Networks
The Core network of the public switched telephone network
(PSTN) is now being replaced by packet (mainly IP) based
data network providing multiple services.
Access Networks
Access loops will be upgraded from copper to advanced loops
such as fiber optics (FTTH/P) and/or innovated wireless
technologies to realize the full potential of NGN core networks.

Newly raised Concerns related to NGN
Core Networks
Access Networks
(1) Threat of unilateral technological
arrangement of interfaces by incumbents
(2) Installation of new nodes may result in
changes for locations where competitors
interconnect their networks.
(3) New Nodes with ‘soft switch’ enable
incumbents to offer their new services without
added construction.
(4) New regulatory regime for interconnection
including VoIP services will be required.
(5) Threat of bundling and discounted services
in fixed and mobile converged core network by
incumbents.
(6) Adverse effects posed by changes in
operation supporting system, function of
intelligences and so on.
All copyrights reserved (MIC)
(1) Replacement of copper local loops
will foreclose customers of competitors
who rely on existing copper loops to
provide their DSL products.
(2) Incumbents are insisting on a
‘regulatory moratorium’ to upgrade
loops as an incentive for new
investment.
(3) Incumbents’ advantage as they can
more easily transfer existing telephone
customers to their new loops.
(4) Competitors insist on equal
treatment in deploying their own FTTH
by removing ‘historical advantage’ of
incumbents related to right of way.
New policies are required

Two Types of Revenue Models of Telecommunications
Two types of telecommunications revenue models
1. Facility-based business
Installing a telecommunications circuit network and recovering network investment over the long term (15-20years)
2. Service-based business
Providing services as a result of the installation of network equipment (e.g. router, server) and lease of telecommunications
circuit networks from other carriers and recovering investment over the short term (2-3years)

Growing Pains of Network Paradigm Shift
Demand is a function of “price”. Demand and Supply has two balanced points in the network industry.
Each point of balance represents an entirely different market situation. Our policy target is to avoid
remaining at “A” and to shorten the transition period from “A” to “B”.
Price

Encouragement of NGN transition from PSTN
Facilitation of VoIP diffusion by allocating
telephone numbers
Increase of interconnection charge
by traffic reduction has resulted in
facilitating full unbundling products
and competitors’ FTTH deployment
Japan’s leading model – VoIP Specific numbers
starting from “050” since Sep 2002
In some OECD countries, regulators are trying to ensure that VoIP service
providers have special telephone numbers which differ from those of the PSTN.
In Japan, for example, the popularity of VoIP services and interconnection
requirements of the PSTN and VoIP services led the government to take a
unique regulatory approach to the numbering plan for IP terminal devices.
While traditional circuit-switched telephone numbers start from 0XX in Japan,
IP telephone numbers are principally distinguished from them by starting from
050.

[Ref] Framework of Universal Service
Background and objectives
◆ Following the privatization of the old NTT Corporation and introduction of competition in the telecommunications marketplace in 1985, the newly
privatized NTT East and NTT West and associated holding companies were obliged under the NTT Law to provide universal service in the form of
telephone services on a nationwide basis.
◆ Competition flourished in regional communications markets, particularly the profitable major city regions. In 2001, it was recognized that universal
service should be achieved not only via complementary internal arrangements between NTT East and West, but also by seeking contributions from
other operators. The Telecommunications Business Law was amended to this end, although the basic obligations under the NTT Law remained.
◆ The amendments set out an obligation to provide universal service in the form of telecommunications services throughout the nation for the benefit of
all citizens
◆ The cost to NTT East and West of the complementary internal arrangements designed to provide universal service was calculated on the basis of
objective standards, and other telecommunications operators benefiting from the use of facilities and connection services associated with universal
service provision were asked to make contributions commensurate with their benefits (user-pays principle)
Changes to the system
Scope
◆ Scope of universal service
Subscriber lines, public telephones, emergency communications
◆ Mobile telephone and broadband services are still in a growth phase
and are excluded from the scope of universal service at this point in
time (Telecommunications Council, October 2005
Mobile telephone services
- Network infrastructure development through competition among
operators
- Unlikely to replace fixed telephone services since charges are
roughly double
- Considerable investment required to provide coverage in
remaining unserviced areas
Broadband services
- Network infrastructure development through competition among
operators
- Service availability rising steadily, but take-up still in a growth
phase (penetration = 37%)
Revenue-cost formula (offset model)

Policy and Regulation to promote competition of DSL in Japan
• Japan’s success in broadband is brought about by LLU-based competition, where operators can pursue differentiation
through speedup of their DSL access services (“competition at deeper levels of infrastructure”) .
• In the case of competition based on resale/bitstream access, speed competition cannot be expected because competitors
rely mostly or entirely on the network of incumbents.
• Japan’s MIC (Ministry of Internal Affairs and Communications) has been implementing following measures.
I. Regulations on Prices of Line Sharing
• The MIC has been regulating the prices of line sharing at a level of around 1€/month (¥120 in the case of NTT East).
• The calculation of these prices is based on the idea that subscriber-line costs are already recouped through telephone basic charges and
that costs incurred by shared access are only those brought by its additional function.
II. Development of Co-location Rules
• Although there were disputes among operators related to co-location at the early stage of DSL rollout, rules for realization of timely and
appropriate co-location have been developed through dispute resolution by the Telecommunications Business Dispute Settlement
Commission, among others.
III. Unbundling of Dark Fiber for Interoffice Transport
• In Japan, dark fiber for interoffice transmission is required to be unbundled and its prices are subject to approval by the MIC.
• DSL access providers thus can adopt the latest technology by using dark fiber, instead of leased lines, at reasonable prices.
IV. Line of Business Restriction on Incumbent Operators
• NTT East & West, incumbent regional operators, are prohibited from engaging in the ISP business directly by themselves.
• This line of business restriction leads to razor-sharp competition at the retail (or ISP) level, which eventually brings about competition at the
wholesale (or DSL access) level where NTT East & West hold only a 37% market share.

[Access charges]
NTT East: \1.917 (monthly fee per meter)
NTT West: \1.920 (monthly fee per meter)
(NB)NTT East/West have independent access charges from FY02.
Therefore the cost price and income from the access fees should balance out.

Competitive pressure has led more investment to FTTH in Japan’s case
DSL market competition
Importance to deepen competition in
DSL market for higher speed access
(1) Users familiar with broadband
discover new ways of usage and tend
to seek higher speed access. To say,
they are ready to use FTTH.
(2) NTT East and West which have lost
majority share in DSL market will
want to recapture lost customers and
transfer their existing telephone
users by the provision of FTTH
services.
(3) Increasing DSL user number encourages
operators to provide triple play
services.
(4) Content and application providers try
to offer more and more audiovisual
rich services to attract end users.
All copyrights reserved (MIC)
FTTH market competition
Investment to FTTH under competition
(1) Increasing number of potential
FTTH users enable operators to
reduce price per customer and
make intentional deployment plan.
(2) Competitors such as electric
affiliates and cable operators
aim at the first mover to deploy
FTTH who will grab a lion’s share
of customers.
(3) Operators including NTT East and
West increase their investment to
FTTH under the recognition very
difficult for rivals to recapture
customers from the first mover.
(4) NTT East and West hope to
accelerate FTTH deployment to
shorten inefficient co-existing
period of both PSTN and NGN.

Transition of subscribers in broadband access services in Japan
•Broadband subscribers have rapidly increased recent years. (The total has exceeded 20.6M)
•The world’s first optical access service for ordinary families was introduced in Japan in March, 2001.
•DSL is still more subscribed than FTTH in total; however, FTTH shows faster increase in net subscription increase.

FTTH : Demand Stimulation by Forward-looking Cost Method
• This method uses average charges calculated with the predicted cost and demand for the next
several years.
• The cost price and the access charge should balance out during the said period.
• This method is especially desirable for NGN because it allows NTT East/West to collect full
investment in fibre.
• At the same time, we can suppress the level of charges though the cost per line is very high
because of the small demand at the beginning.
Fiber local loop access charge

[Ref] 'The alternative, and more nuanced, policy
which we have identified is to have a time
varying schedule of access prices – more
precisely for access prices to rise over time
relative to incremental costs. This régime
gives entrants benefits at the start of their operation,
when they have replicated only a few of the
incumbent’s assets, and an incentive progressively
to extend their own infrastructure.'

NTT East/West’s deployment of Fiber Local Loops
１）The amount of NTT E/W’s investment in optical fiber has been increasing steadily even after FY
2001 when fiber local loops were unbundled.
２） In FY 2003 especially, the actual ratio of investment in fiber local loops was much higher than that based
on the plan.
３）Actual costs higher than forecast in FY2001 - FY2004. On the other hand, NTT released medium-term strategy
including plan to provide optic fiber services to 30 million households by the end of FY2010.

Open access regulation and sustainable investment to FTTx
1 Issues do not exist in unbundling itself, but its price level.
•
•
Every operator might be required to make faithful negotiation on
interconnection with others.
Without unbundling products, Incumbents can not only transfer their existing
market power on copper lines onto new FTTx, but also can get back
competitors’ DSL customers depending on copper lines.
2 Price setting is more important to give network investment incentives.
•
•
Incumbents to be allowed to include risk premium in the price.
Pricing to shorten transition period considering future demand increase.
3 “Parasites” to Incumbents should not be allowed.
•
•
Service-based competition is different from “parasitism”.
Pricing is important again from the viewpoint of avoiding continuous parasites.

The importance of “Equal treatment” in deploying local loops
1
The essence resides in the difficulty to replicate local loops
(economic bottleneck) .
2
The difficulty is not always derived from the ‘high cost’ of
deployment.
a.
b.
c.
3
Construction cost is expensive. But maintenance of copper lines is more
expensive compared with FTTx.
Optical fiber in itself is much cheaper than copper.
Someday existing copper lines shall be replaced into an upgraded network
after depreciation in the case of Incumbents.
Competitors should be encouraged by removing invisible barriers
and inequalities and ensuring equivalence in construction.
a.
b.
c.
From the viewpoint of facility-based competition, it is more critical to enable
competitors to deploy their own FTTx on an equivalent basis in road digging,
access to conduits, ducts, poles, etc.
Incumbents may be reluctant to open their property for competitors’ FTTx
for many excuses and receive favorable treatment by electric companies,
road administrators etc, through long-time relations.
Competition will also lead to the increase of incumbents’ investment.

Outline of KDDI's IP Migration of PSTN Network
(released September 15, 2004)
１ Past Efforts (Introduction of New Services)
○ KDDI launched “KDDI Hikari Plus” which provides triple play service,
including Video, high-speed Internet and high-quality IP phone, by
optical fiber in October of 2003.
○ KDDI also launched “KDDI Metal Plus” which connect subscriber phone
line (Dry copper) directly to KDDI’s IP network (without using NTT’s
Switch) in February of 2005
２ Schedule for IP Migration of PSTN Network
○ KDDI intends to finish fixed IP migration ahead of others in the world
and to provide inexpensive services using IP technology even to
customers who do not subscribe to broadband.
○ Initiating fixed IP migration in FY2005 and finishing substitution of softswitches by the end of FY2007
○ Establishment of an environment where introduction of new IP-based
services is possible with ease through IP migration

“Demand Stimulation” looking at upper layers such as
platform and Content/Application (ex. IP-TV)
1.
“Broadband” inevitably to be interested in upper layers
seeking new demand
2. IP-TV: a typical example likely to hold appeal to
prospective customers
3. Resolution of anxieties from new interested parties such
as broadcasters and rights holders
(1) Rebuilding of broadcasters’ business model
(2) Threat of piracy
(3) Revenue Distribution Mechanism to content holders
(4) New business model for platform/aggregation layer

Competition in communication markets
■ Competition in the domestic long-distance communications market originally revolved around NTT, KDDI and Japan Telecom.
With the advent of broadband services, the main players are now NTT, KDDI, SoftBank, the power companies and CATV.
Increasing competition is also expected in the mobile telephone market as new entrants emerge.

NGN Standardization Trend at the global level
○ ITU started standardizing NGN which began replacing existing PSTN in 2003.
⇒The architecture (1 st version) will be determined in early 2006.
○ In Japan, the Information and Communications Council is considering this matter in cooperation
with the Telecommunication Technology Committee.
[Main characteristics of NGN]
Independency of service-related functions from underlying transport-related technologies
• transport-related technologies designed basically based on IP protocol
•service-related functions do not rely on network infrastructure and provide service-related functions including the basic
and added functions of telephony, video phone and distribution of contents
⇒enable development and deployment of equipment with high flexibility, approach to the latest element
technologies and diverse e of business

Current Status of Efforts Related to the Improper Use of Telecommunications Services
Points for Discussion
[1. Spam mails]
Advertisement emails are sent to mobile phones or computers
one-sidedly and in large volumes
<Related laws: Law on Specified Electronic Mail, etc.>
Efforts of the MIC
 Amendment of the Law on Specified Electronic Mail (enforced in November 2005)
 Establishment of new rules for criminal punishment for faking information on the sender, etc.
 “Spam Blocking Support Project” under collaboration of the government and the private sector
(February 2005 - )
 Promote the suspension of lines, etc. by telecommunications carriers
 Legal organization of the exchange of spam sender information (black lists)
 Amendment of the guidelines for the protection of personal information (October 2005)
 Promotion of international cooperation (Agreed on memorandum of understanding with Asian
countries in April 2005)
[2. Phishing]
Damage from "phishing" - the fraudulent acquisition of personal
information over the Internet through emails disguised as coming from
banks or other companies - has been seen also in Japan
<Related laws: Criminal law (fraud charges), Unauthorized Computer
Access Law, etc.>
 Regular meetings of a "Liaison Group for the Promotion of Phishing Countermeasures“
(January 2005)
 Aim to share information among industry associations, etc., and study into effective
countermeasures such as the introduction of sender domain authentication technology
(Published interim report in August 2005)
[3. Billing fraud]
Prepaid-type mobile phones, etc., which have a high degree of anonymity,
are used for crimes such as "Ore ore sagi" ("It's me, it's me!"-fraud; fraudulent
crank calls where the caller pretends to be a member of the family needing
help), or billing fraud
<Related laws: Law to Prevent the Illegal Use of Mobile Phones, etc.>
[4. Illegal and harmful content on the Internet]
Illegal or harmful information is posted on electronic bulletin
boards, etc. on the Internet
<Related laws: Provider Liability Limitation Law, etc.>
 Establishment of the "Law to Prevent the Illegal Use of Mobile Phones“ (Partial enforcement in
May 2005, full enforcement planned for April 2006) -> obligation to confirm identity, etc. when
signing a contract for or transferring ownership a mobile phone
 Confirmation and registration of all contract owners for prepaid-type mobile phones
 Suspension of use of confirmation is impossible (measure in the terms of contract, until March
2006)
 Enforcement of the "Provider Liability Limitation Law" and related guidelines (May 2002 - )
 Regulations for standards on exemptions from liability for the deletion of information by providers,
etc.
 Promoting "R&D for mobile filtering technology" (fiscal 2004 - 2005)
 Support for the establishment of industry guidelines related to the response to suicide
announcements（October 2005）
 Organization of a "Study Group on the Response to Illegal and Harmful Information on the Internet"
(August 2005 - , published interim report in January 2006)
[5. Protection of personal information]
Personal information is frequently leaking out
<Related laws: Law Concerning the Protection of Personal
Information, etc.>
All copyrights reserved (MIC)
Wide-ranging amendment of the guidelines for the protection of personal information on the
basis of the discussions in the "Study Group Concerning Information Privacy in the
Telecommunications Business Field" (chaired by Prof. HORIBE Masao, Chuo University)
(August 2004)
 Implementation of strict guidance, etc. for businesses leaking personal information on the
basis of the Law Concerning the Protection of Personal Information and the amended
guidelines

New Challenges with NGN
1.
Cross-Layered and Comprehensive Approaches
- Everything on IP network and layer-based activities (1) Modulization from Network layer to Application layer
(2) Trend of Convergence: Vertical and horizontal integration or alliance for FMC,
Communications and Broadcasting Convergence, and triple play
(3) To encourage users’ convenience through convergence
(4) Necessity to watch all layers and comprehensive policy over layers
2.
Emerging concerns about competition policy
(1) Monitoring the abuse of market power over layers/vertical integration
① To ensure fair competition among wire and wireless operators
② Securing of impartial access to bottleneck facilities for rival competitors
③ Provision of opportunities for equal access to Content/Application for end
users
(2) To avoid anti-competitive effects of NGN deployment by Incumbents
① Concerns to transfer Incumbents’ existing market power to NGN
② Necessity of open cooperation in construction of NGN between
Incumbents and Competitors
