INTRODUCTION – REGULATION OF
INTERCONNECTION

CANTO 2006 - 18-21 June 2006 – Punta Cana
Introduction – Regulation of Interconnection
• Interconnection is a necessary and mandatory
requirement in a liberalized
telecommunications environment
• Regulation aims to create a leveled playing
field
• Interconnection agreement negotiation:
complex task with high stakes
– Even more difficult with current migration to IP
networks

CANTO 2006 - 18-21 June 2006 – Punta Cana
Introduction – Regulation of Interconnection
• The need for regulation of interconnection
– Competition is generally recognized as key to
growth and innovation in telecommunications
– Two basic principles for an efficient and
competitive telecommunications sector
• The possibility for users to call anywhere, i.e. across
networks
• Protection against abuse of market power
– Obligation for all operators to provide fair and
equitable interconnection, for all services
• Efficient use of rare and expensive resources
• Allows all users to communicate with one another

ARRIVAL OF NEXT GENERATION
NETWORKS (NGNs)

Arrival of Next Generation Networks (NGNs)
• Internet realities

Internet traffic roughly doubling every year
Voice traffic growing at 5% per annum
VoIP growing 40-80% per annum
However, Internet does not dominate global communications
in market size, number of users, traffic
Internet a small fraction of global network infrastructure:
telephone, satellite, radio, TV, private networks
Internet revenues growing at 17% per annum, phone at 6%:
will take 15 years to surpass phone revenues
ISP revenues < 5% of total communication revenues
Internet users worldwide 800 million+

Arrival of Next Generation Networks (NGNs)
• Key drivers transforming telecom business to IP
networks and services:
– Telecommunications business is becoming informationbased
– Data communications exceeding voice worldwide
– Circuit-switching optimal for voice communications
– Packet-switching optimal for most data communications
– Internet becoming the ‘all’ communications network
– IP packet-switching protocol is basis for Internet
– Major operators are merging their communication networks
into one ubiquitous IP packet-switched network carrying all
forms of communications

Arrival of Next Generation Networks (NGNs)
• Next Generation Network – ITU definition
– A packet-based network able to provide telecommunication
services and able to make use of multiple broadband, QoSenabled transport technologies and in which service-related
functions are independent from underlying transport-related
technologies
– Enables unfettered access for users to networks and to
competing service providers and/or services of their choice
– Supports generalized mobility which will allow consistent
and ubiquitous provision of services to users

Arrival of Next Generation Networks (NGNs)
• Operators are investing in NGNs to compete with
Internet
• NGNs are being deployed
• Convergence is happening
• NGN interconnection settlement model cannot follow
traditional PSTN or Internet models

NEW INTERCONNECTION ISSUES
Interconnection Issues Related to NGNs
CANTO 2006 - 18-21 June 2006 – Punta Cana
New Interconnection Issues
• General issues
– The interconnection between legacy circuit-switched
networks and new IP packet switching networks - every
conversion between the Time Division Multiplexing (TDM)
and IP domains introduces delay and distortion, which result
in poorer voice quality
– Additional levels of interconnection required between the
basic backbone IP packet network and many more new
competitive players
– The push to open interconnection standards at all points and
levels of technical interconnection
– The increasing regulatory liberalization for interconnection

– Tele-management
• Continue to bill on the basis of duration or volume?
– Inter-operator billing systems
• How to handle the increasing number of partners and
complexity of business transactions?
– Reconciliation and reporting

• How to handle arrangements between more than two
providers involved in a given transaction?
– Clearing houses (iNOW, OSP)

CANTO 2006 - 18-21 June 2006 – Punta Cana
New Interconnection Issues
• International settlements
– Market evolution:
• New services and technologies (i.e. NGNs) will probably
be built assuming “invoicing model” will apply
• New market entrants do not want to invest in billing
systems that cope with a complex model (ITU) and its
financial implications
• Increased market volatility and risk argues for faster
payment

THE FUTURE
Interconnection Issues Related to NGNs
CANTO 2006 - 18-21 June 2006 – Punta Cana
The Future
• A separation of service provision and connectivity
• NGNs that support new services and third party
services over network boundaries
• Easy provision of new and third party services - the
deployment of NGNs provides an excellent
opportunity to agree on improved interfaces to
enable service providers to interconnect and
cooperate in the delivery of services
Interconnection Issues Related to NGNs
CANTO 2006 - 18-21 June 2006 – Punta Cana
The Future
• A variety of charging schemes: transport- or usagebased, content-based, hybrid, etc
• The adoption of hybrid and different settlement
methods: peering (sender keeps all) between
providers of the same service, invoicing to third party
service providers, etc
• Class-based rather than service-based measures to
improve quality
• New regulatory policies that recognize the freedoms
inherent in NGN architectures

The Future
• Interconnection between operators that allows the
provision not only of today’s and tomorrow's voice,
data and multimedia services, but also of an
unlimited range of new applications and services
limited only by human imagination
